Could displays correct your vision? "New technology under development at the University of California-Berkeley and MIT automatically corrects people's vision defects without glasses. Plug a glasses prescription into the new software, and the system calculates how to display the image so it won't look blurry. Basically, by adjusting the light from each pixel on a device and then passing it through a tiny mesh attached to a monitor or phone screen, the system personalizes the image so it's crystal clear." via Fast Company

How will liquid crystal displays help reach exaFLOP speeds? "The Optalysys Optical Solver Supercomputer will initially offer 9 petaflops of compute power, increasing to 17.1 exaflops by 2020. 40 gigaFlops demonstration uses 500x500 pixels working 20 times per second. Each pixel does the work of about 8000 floating point operations in each of the cycles. Speeding up 427 million times to 17.1 exaFLOPS can be done with 500,000 X 500,000 pixels and 8550 cycles per second. They can use multiple LCD displays. ...There was no need to drive the refresh rate up for human displays but there will be a need for optical computing. 4K monitors usually have 8.3 million pixels (3180X2160). Thirty six thousand 4K monitors would get to 500K X 500 K." via Next Big Future

Is quantum dot the next step in LCD TV evolution? "Some brands have adopted quantum dots in their products, such as Amazon’s Kindle Fire HDX tablet PC and Sony’s Triluminos TV in 2013. However, quantum dots must surmount some hurdles to achieve wide usage. The first is the issue of Cadimium, which most quantum dots contain, and which is a regulated substance due to enviromental concerns. The second is the high price of quantum dot materials. Quantum dot makers are working on solving these issues. For example, Nanoco has produced Cadmium-free quantum dot materials, and other makers have secured a temporary exemption for Cadmium in products with quantum dot-based displays imported into Europe. Regarding price, many materials and films makers are entering the market, especially from Korea such as Samsung, LG, Sangbo, LMS, Hanwha and SKC-Haas. Increased competition will likely help to lower prices in the near future." via ECN Mag

Will superconducting quantum dots make LCD displays more vibrant? "Eric Nelson, who is also behind the development of the technology, says that it is called quantum dot enhancement film (QDEF), which enhances the colors of LCD screens. Nelson explains that current technology consumes a lot of energy to display bright colors on the LCD screen. However, QD efficiently provides high-color display and consumes far less energy when compared to other technologies. ..."They sandwiched the QDs between two polymer films, with the QDs embedded in an epoxy glue. Coatings on the film provide further protection and enhance the viewing experience," per ACS." via Tech Times

Who made the world's first touch-sensitive LCD basketball court? "Nike has created this huge touch-sensitive LCD basketball court for a training session with Kobe Bryant. The court has built-in motion sensors that track every player's movements individually. It can also display training exercises for them to follow and show statistics on performance.

Display database for engineers Search thousands of display panels by multiple characteristics and compare results side-by-side using the display database multisearch.

Could this new type of heads-up display redefine the augmented reality experience? "Andrew Maimone’s device is called a Pinlight Display and he has been working on this device in collaboration with three researchers from the University of North Carolina and two from Nvidia Research. The Pinlight Display does not rely on standard optical components. Instead, it utilizes an array of “pinlights”, which are essentially bright dots. Maimone explains that “A transparent display panel is placed between the pinlights and the eye to modulate the light and form the perceived image.” He added that "Since the light rays that hit each display pixel come from the same direction, they appear in focus without the use of lenses." (Video)" via Mobile Commerce Press

Will Quantum Dots Dominate Displays? "The QD Vision approach adds quantum dots to strips of blue LED edge lights around an LCD panel. Some of this light is converted to red and green, which is mixed by a light guide to create a high-quality white backlight for the LCD panel’s color subpixels. The Nanosys/3M approach places the QDEF film over the back of the panel, and then a blue LED backlight is applied (typically through edge lighting and a light guide). Some of the blue light is converted in the film layer to red and green light before reaching a subpixel. A new, third, approach is being developed by a number of researchers. This involves putting the quantum dots directly on the blue LED chip. This can simplify the optical and light-management requirements, but it subjects the quantum-dot material to higher operating temperatures that can decrease performance." via IEEE Spectrum

LEDs Made From ‘Wonder Material’ Perovskite "A hybrid form of perovskite – the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon – has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible color displays. This particular class of semiconducting perovskites have generated excitement in the solar cell field over the past several years, after Professor Henry Snaith’s group at Oxford University found them to be remarkably efficient at converting light to electricity. In just two short years, perovskite-based solar cells have reached efficiencies of nearly 20%, a level which took conventional silicon-based solar cells 20 years to reach." via redOrbit

TouchPico projector creates touchscreens anywhere. "The secret to the touch interaction is in the TouchPico stylus. The built-in infrared camera determines the touchscreen coordinates and relays that information to the projector at up to 40 frames per second. That’s fast enough to play some Fruit Ninja and score. This definitely takes interaction above and beyond the combination of laptop, projector and some gyroscopic mouse. The TouchPico can definitely up your professional game, too" via TechnologyTell

Can new automotive heads-up display be alternative to smartphone while driving? "Navdy wants to change the way we interact with our connected devices while driving altogether. It’s a device that can be mounted on any car’s dashboard and it provides a high-resolution heads-up display that helps you see the road behind it. Simpson says the technology is the same used by pilots when they land an airplane. By seeing what’s behind the display and still receiving information from it, the driver doesn’t take his or her eyes off the road, which should decrease the chances of an accident according to the NHTSA, which released guidelines last year to minimize in-driving distractions such as manual text entry on navigation systems." via TechCrunch

Spheree lets you watch animated images in full 3D "Spheree is the work of a team of researchers working together from the University of São Paulo, Brazil, and the University of British Columbia, Canada, and it's mesmerising to behold. Like its name suggests, it's in the shape of a translucent sphere; inside, the viewer can see animations and images that appear to float in the centre; as the viewer moves around, they can see other sides of the object as their perspective changes. And it's all based on optical illusion. Packed inside the Spheree are multiple mini-projectors, which shine the images onto the interior surface of the sphere. Special software designed by the team blends the projector images together for a single, seamless image." via CNET

5 Things CIOs Should Know About Digital Signage "4. Networks will be put to the test. An increasing percentage of digital signage content will be in ultra-high-definition (UHD), which could swamp an organization’s network bandwidth, particularly if the content is pulled from the cloud instead of being stored and played locally, says IHS analyst Sanju Khatri. Digital signage using UHD displays first appeared at McCarran International Airport in Las Vegas in 2013, and IHS predicts huge growth in UHD displays in the next few years." via CIO

Creating Next-Generation Holograms "Researchers from the University of Cambridge have developed a new method for making multi-colored holograms from a thin film of silver nanoparticles, which could greatly increase the storage capabilities of typical optical storage devices. ...Using a single thin layer of silver, Montelongo and his colleagues patterned colorful holograms containing 16 million nanoparticles per square millimeter. Each nanoparticle, approximately 1,000 times smaller than the width of a human hair, scatters light into different colors depending on its particular size and shape. The scattered light from each of the nanoparticles interacts and combines with all of the others to produce an image. The device can display different images when illuminated with a different color light, a property not seen before in a device of this type. Furthermore, when multiple light sources are shone simultaneously, a multi-color image is projected." via Controlled Environments

What does automotive HMI technology have in store for the near future? "There is much potential for in-car HMI, but we have yet to see a similar revolution in the UX and UI of the automotive industry. ...However, in the haste to get on-trend, car manufacturers have simply used screens to replicate what has been before, rather than taking an empathetic, intelligent approach. Skeuomorphism abounds, where physical buttons are replaced with look-alikes on a screen — familiarity is retained, but at the expense of tactile feedback. Current touchscreen HMIs are often simply ill-considered re-appropriated solutions developed for completely different contexts (which we will discuss later in the series)." via ITProPortal

Is 4K the next flat panel display revolution, or another gimmick? "While 3D may not have stuck around, now every film is projected in 4K. However, there are circumstances when the benefit of 4K can’t be fully utilized, and it has to do with viewing distance. To perceive the full benefit of a 4K resolution, the human eye needs to be at a certain distance from the screen, depending on the size of the screen. This is also true for 1080p over 720p. "In general, from an integrators perspective, we try to look at what the viewing distance or the vieiwing angle of the folks involved might be," says Mike Hancock, Vice President at MechDyne Corporation. "Flat panels, except for some of the really extreme large-sized ones, really only work good for rooms that are less than 20 feet."" via CorporateTechDecisions

Foldable, Bendable And Bright: The Future Of Displays "Micro transfer printing (µTP) is a method of, essentially, using a type of rubber stamp to pick up very thin strips of semiconductor material (as the “ink”) and place it somewhere else by “stamping” it. The advantage of this technique is that it allows you to put high performance semiconductor elements (such as gallium nitride (GaN)) onto substrates where they wouldn’t normally be compatible (like plastic). And you can place the stamp over and over thereby creating large areas of arbitrary shapes out of otherwise small, high performance components—in ways that are impossible or infeasible with traditional semiconductor manufacturing processes. Prof. John Rogers describes in the Science paper making displays out of micro-LEDs using transfer printing. The micro-LED displays had great battery life, were very bright and, due to the nature of µTP, could be made at low cost. The trifecta of low cost, good battery life and a scalable manufacturing platform while maintaining excellent performance comprises the display industry equivalent of winning eight gold medals in the same Olympic games. It’s a big deal, and Rogers may have delivered it." via Forbes

New automotive head-up display could help drivers avoid collisions in fog "The head-up display (HUD) is the work of Professor Vassilis Charissis and his team, based in the Virtual Reality and Simulation Laboratory (VRS Lab) within the School of Engineering and Built Environment. The display has been developed and evaluated in a 3D driving simulator, which allows drivers to navigate a perfectly recreated stretch of the M8, M74 and M80 in a choice of conditions. One of the options lets the driver tackle the motorways in dense fog, before giving them the chance to drive the same stretch again using the head-up display. When initiated, the windscreen of the car highlights where other vehicles are on the motorway within a 400-metre range and even lets the driver know when it’s safe to change lanes." via FleetNews

A Vision of Future Displays "According to Brown Elliott, Samsung has not used even half the IP they have developed and will need some time to roll out what is already possible for the next few years. But Samsung’s loss could be someone’s gain. As I said in the beginning, Brown Elliott has a vision of the display industry in 10-15 years. The way she sees it, light field displays and light field imaging devices will merge in this time period. That means a clear sheet of glass (or plastic) will be both camera and display. With a light field display, a lens is placed above a number of pixels that can provide “views” from many directions. Current light field displays and imagers are always pixel limited so the resulting images are typically 50-200x lower resolution than the underlying display resolution." via Display Central

Could New Vision-Correcting Display Free Users From Their Glasses? "The technology uses algorithms to alter an image based on a person’s glasses prescription together with a light filter set in front of the display. The algorithm alters the light from each individual pixel so that, when fed through a tiny hole in the plastic filter, rays of light reach the retina in a way that re-creates a sharp image. Researchers say the idea is to anticipate how your eyes will naturally distort whatever’s onscreen — something glasses or contacts typically correct — and adjust it beforehand so that what you see appears clear. Brian A. Barsky, a University of California, Berkeley, computer science professor and affiliate professor of optometry and vision science who coauthored the paper, says it’s like undoing what the optics in your eyes are about to do. The technology is being developed in collaboration with researchers at MIT and Microsoft." via Mashable

Will AMOLED display panels be cheaper than LCD within 2 years? "According to the NPD DisplaySearch OLED Technology Report, manufacturing costs for AMOLED panels are currently 10 to 20 percent higher than for TFT-LCD displays; however, considering the rapid improvement in AMOLED panel production yields, the manufacturing costs for AMOLED mobile phone panels are expected fall below costs for LCD mobile phone panels within the next two years. ...Early on, AMOLED panels were expected to cost less than LCD panels, because they do not require backlighting. Instead, production challenges kept AMOLED yields low, and thus costs remained higher than for equivalent LCDs. AMOLED became a high-end product, due to its high color gamut, good contrast, and slimness. Recent production yield improvements are expected to help AMOLED penetrate more broadly into smartphone panels." via LEDs Magazine

How Strong Is Your Industrial LCD/LED User-Interface IQ? "Both LEDs and LCDs provide significant benefits to industrial control applications. In addition to well-documented benefits – such as a 70 to 80 percent reduction in energy requirements, enhanced durability/shock/vibration resistance and extended lifetime – recent technological advances have generated additional, particularly beneficial features. New extended temperature ranges for both LCD and LED displays, nonbulky heaters and cost-effective custom solutions have revolutionized user-interface displays for industrial control applications. Identifying a supplier with expertise in both LED and LCD technologies, as well as in integrated solutions, is key. Combining this with value-added services allows design engineers to develop user interfaces that provide cost savings, reliability and enhanced visual performance in even the most challenging of industrial environments." via Industrial Photonics

Watch LG’s large bendable and transparent displays in action "The video above shows LG Display’s 18-inch polyamide-based rollable display with a curvature radius of 30R. In practice, that means you can bend the panel back and forth without damaging it, but we’re still a few years away from panels you can roll up like a sheet of paper and carry in a tube. Also, the current model is just 1200 x 810, a resolution that is in no way suitable for commercialization. But LG Display is confident it can iron out the technical kinks and bring a 60-inch panel of 4K resolution that can be rolled up in a 3 centimeters tube by 2017. (Video)" via Android Authority

Japan Display Begins to Mass Produce IPS-NEO Displays "Liquid crystal panel manufacturing requires an orientation process that aligns liquid crystal molecules in a uniform direction. Generally, the rubbing method, as portrayed in the diagram below, is employed. In this process, an orientation membrane is rubbed in a fixed direction with a rubbing roller with cloth wound on it. With this method, unevenness of the circuit pattern formed on the glass substrate could impede proper orientation and the involvement of foreign particles in the rubbing process may affect the production yield. Adopting JDI’s photo alignment method, IPS-NEO is free from these issues and achieves a higher contrast, superior viewing angle characteristics and an improved production yield." via Xbit Laboratories

MediaTek Unveils First Mobile 120Hz Display Technology "Key to this breakthrough is MediaTek's Response Time Enhancement Technology, which significantly decreases the display's response time and reduces motion blur experienced on 60Hz display by up to 50%, bringing everything on the screen to life with crisp and smooth motion. In addition to the Response Time Enhancement Technology, MediaTek ClearMotion(TM) featured in the SoCs ensures full utilization of the 120Hz display with automatic frame rate conversion for content that is standard 24fps and 30fps videos and displays them in 120fps, putting the best and smoothest viewing experience in the hands of consumers around the world. These advancements are a demonstration of MediaTek's commitment to developing high-quality solutions that foster limitless creativity and innovation." via IndiaTimes

What kind of display does wearable tech need? "There are also challenges with smartwatch displays. "On one hand you have Pebble. On the other side you have awesome looking high-resolution color displays that are completely not readable in daylight and that use more power. This is your choice today. There is no magic pill. You have to pick one. For the next two years, wearables will suffer from this problem," Joire said. Joire said Pebble chose a monochrome E-paper screen so that it would be visible in daylight and preserve battery life. "Most of the time for a smartwatch at least, you're not using it when you're indoors because you have your phone. You generally use it when you're walking somewhere outdoors. So we picked that side of the fence. But nothing stops us from making two watches," Joire said." via TechRepublic

InkCase Plus Adds A Second, Standalone E-ink Screen To Your Android Phone "Meet InkCase Plus: a second companion screen for your Android smartphone that’s designed to slot into a case so you can stack one pane atop the other, sandwich style. Currently it’s just a Kickstarter prototype, with its makers looking for $100,000 in crowdfunding to get the device to market. ...Now it’s worth saying we’ve seen this idea before. In fact Russian startup YotaPhone makes a dual-screen smartphone that incorporates an e-ink screen onto the rear of the phone — which is especially neat (not least because it’s not so chunky). However G-Jay Yong, CEO of Oaxis, the company behind the InkCase Plus, reckons the standalone Yota-concept-clone has advantages over a single combined device — since you can view your two mobile screens side by side if you like. In other words, it doesn’t have to be one or the other." via TechCrunch

Are flexible organic TFTs closer with new breakthrough? "In Japan, the International Center for Materials Nanoarchitectonics (or MANA for short) has announced another step forward for display technology, in the form on a new Nano Ink that can be used in the printing of flexible organic thin film transistors (OTFT) at room temperature. TFTs are an essential technology used in display backplanes, and are responsible for controlling the light parts, be that LCD or OLED, of the visible display. Although printed circuitry has been in development in various forms for a little while, MANA claims to have developed a new technique which overcomes the high temperature annealing processes typically associated with printed electronics. This means that its technique can be used to print more complex components onto plastic substrates, which is perfect for flexible electronics and display products." via Android Authority

Does Google Glass have potential as a medical display? "Karandeep Singh believes Glass can successfully improve clinical efficiency and physician-patient interaction if introduced in the right way. “In a medical setting, it will be perceived differently than in a public setting,” he said. “When you’re with a patient, that’s a different social contract. And if you’re viewing private patient information, what better way to display it to you than in a way that only you can see it?” One of the functionalities Singh has engineered is for Glass to connect to patients’ electronic health records. Though designed to improve efficiency, clicking and scrolling on a computer leads a physician to spend a significant amount of time turned away from a patient. And some physicians find it hard to synthesize disparate pieces of data as they click through. “The big mistake many people make is that they assume that the Glass is replacing static desktop displays,” said Paul Lukowicz, a professor in computer science at the Technical University of Kaiserslautern in Germany who consults for the companyWearable Technologies. He sees great value in “precise cross referencing” that goes beyond the normal desktop interface." via Nextgov

Samsung’s Head-Up display Will Switch Between Virtual And Real Reality "Samsung‘s VR efforts are one leaky ship lately, with a report today echoing earlier rumors that the company would be partnering with Oculus VR for its own headset. Now, a leaked pre-release version of the Samsung VR software has made its way into the hands of SamMobile, apparently revealing some of the early functionality the head-mounted display will have, and detailing some of its workings. Based on the leaked app screens, the Samsung Gear VR device will indeed mount a Galaxy smartphone in front of your face, likely similar to the way that Google Cardboard works with Android devices. But Samsung’s device will predictably be limited to its own smartphones, at lest according to rumors. It’ll also plug into VR via USB 3.0, which is only supported on current Galaxy devices including the S5 and Note 3, likely because of the increased bandwidth for data made available through use of that connector." via TechCrunch

Advances in capacitive touch and passive capacitive pens "Whatever the technical issues may be, we've now reached a point where customers pretty much expect capacitive multi-touch even for industrial and vertical market tablets. The tap / pan / pinch / zoom functionality of consumer tablets has just become too pervasive to ignore. So we've been seeing more and more rugged and semi-rugged tablets (as well as handhelds) using capacitive touch. That's no problem with Android-based tablets since Android was designed for capacitive touch but, unlike in the consumer market where iOS and Android dominate, but enterprise customers continue to demand Windows on their tablets. Which means a precise pen or stylus is pretty much mandatory. Now what about capacitive pens? They have been around since the early days of the iPad, using a broad rubber tip on a stylus to provide operation a bit more precise than is possible with a finger. How much more precise? That depends. Even slender index finger tips measure more than 10 mm whereas those capacitive styli have tips in the 7-8 mm range. That seems improvement enough for several manufacturers of rugged tablets to include capacitive styli with their products. The tips of those styli are narrower than those of earlier versions, but still in the 5 mm range, and they still have soft, yielding tips. They work a bit better than older ones, but in no way as well as a mouse or an active pen. Not much that can be done, or can it?" via RuggedPCReview

What Advantage Do Curved LCD TVs Have? "One of the main weaknesses of many LED-lit LCD TVs is a relatively limited optimal viewing angle, as compared to plasma and OLED. TVs that use VA (vertically aligned) LCD panels often have deep blacks when viewed head-on, but they quickly lose contrast when viewed from an angle. Even when you sit centered facing a flat screen, you view the edges of that screen at an angle. Depending on how close you sit, that can lead to a loss of picture quality toward the edges of the screen. Now, consider UHD/4K resolution: It requires the viewer to get close to the screen to see all the detail. When viewing a curved screen close up and centered, the viewing angle at a screen's edges stays closer to perpendicular than it does with a flat screen. For one solitary viewer who sits in the right position, a curved LCD screen provides the very tangible benefit of keeping the entire panel aimed at the viewer, which can result in higher contrast and greater uniformity across the entire screen." via AVS Forum

What are Touchscreens of the Future? "Carnegie Mellon's Chris Harrison demonstrates TouchTools and TapSense, tablet apps he built to explore new ways of that people might interact with screens in the future. (Video)" via IEEE Spectrum

How does a transparent display reimagine the ruler? "Glassified is a modified ruler with a transparent display to supplement physical strokes made on paper with virtual graphics. Because the display is transparent, both the physical strokes and the virtual graphics are visible in the same plane. A digitizer captures the pen strokes in order to update the graphical overlay, fusing the traditional function of a ruler with the added advantages of a digital, display-based system. We describe use-cases of Glassified in the areas of math and physics and discuss its advantages over traditional systems. (Video)" via Vimeo

Why are OLED TVs being shunned by the world, but LG is embracing them? "Currently, Samsung and LG use different approaches to OLED panel engineering. As Soneira explains, "Samsung uses an expensive Low Temperature Poly Silicon LTPS backplane for their R,G,B OLED TVs, while LG uses an IGZO backplane with all white OLEDs with R,G,B,W color filters, so their costs are lower." All that tech-speak means is that there is more than one way to skin an OLED cat, and Samsung’s is more involved and costly. Having spoken to Samsung extensively about its OLED methods, we know that the company very much prefers its approach, and is not willing to sacrifice what it feels is superior quality for the sake of cranking out a product that not a lot of people are in a position to purchase anyway." via Digital Trends

LG Unveils Flexible Display That Can Be Rolled Up Like A Piece Of Paper "LG’s display division yesterday announced two new types of panels, a rollable 18-inch OLED panel and an 18-inch transparent OLED panel. ...Instead of using plastic to achieve this level of flexibility, LG said the panel is made out of a "high molecular substance-based polyime film". The transparent panel, as LG explained, has 30% transmittance, which is significantly higher than the 10% transmittance in existing transparent LCD panels. LG says that it achieved this by adopting the company’s transparent pixel design technology and incorporating it into the new display." via Forbes

How Epson Keeps Innovating With R&D "Projector technology too has developed step by step. The 3LCD technology that powers projectors used for offices, education and homes had its origins in 1977 when Epson started to develop the active-matrix LCD chips. In 1982 it introduced the TV watch and later shifted to polysilicon TFT systems, that ironed out picture quality and size issues. In 1984, the company commercialised the world’s first pocket-sized colour TV, the ET-10. In 1989 Epson used 3 LCD technology for its first brand projector and since then High Temperature Polysilicon (HTPS) has been the key component of 3LCD projectors. Ask employees at Epson and they will tell you that R&D is the heart of their organisation. Consumers, for instance have been experiencing Epson products with diverse uses." via The Hindu Business Line

Where Does LG Display Manufacture Its Innovative Technology? "I am at the largest screen factory in the world - LG Display's Paju Complex, in South Korea, on an extensive tour. ...In a bright white space-age showroom, Epic Kim shows us possibilities that OLED opens up. Some of these products have already made it to the market - just. LG sells a inwardly curving OLED TV, which is much more impressive than it sounds, and even a semi-flexible smartphone, named the G Flex. Other innovations have not found a product yet - take the insanely high-resolution smartphone screen that is twice as sharp as an iPhone, the 3D TV that does not require glasses, or the fully transparent touchscreen, which I found the most exciting. Why hide the innards of your new smartphone? Why buy a TV when your whole window can show a movie? Why buy curtains when your window can become a black screen?" via The Age

‘Sensor Salon’ brings LCD screens, 3D-printed objects and sensors to fingernails "That’s the vision of students from the Art Center College of Design in Pasadena, Calif., who presented their “Sensor Salon” project at Microsoft today — explaining how they created a prototype salon that brought together experts in design and development to create made-to-order technology for a client’s nails. Technologies embedded in the nails included small programmable LCD screens, and 3D printed objects and charms. ...Other possibilities would include haptic feedback — sensors that would trigger small vibrations that could help people with bad habits such as smoking." via GeekWire

What Happened At SID Display Week? IDTechEx Summarizes the Show "The impact of the emergence of Chinese manufacturing was not overlooked this year during SID last month, with the opening keynote talk delivered by Wang Dongsheng, president and co-founder of BOE, the largest Chinese display manufacturer. With over 20,000 usable patents and 4,200 patent applications, BOE is in growth mode on a massive scale, with 35% of its products globally launched in 2013. The company is obviously looking to make significant profits from the juggernaut that is the display industry, with an accumulated investment of $260 billion since 1990. Wang Dongsheng though used the term during his keynote "The display industry is suffering from success", referring to its low profitability." via Printed Electronics World

How flexible, micro-thin displays could revolutionize liquid crystal technology "A new research study published in this week's journal of Nature has shown the proof of concept for using what are known as 'phase change materials' – materials that can rapidly switch between amorphous and crystalline states when heat or electrical charge is applied – as building blocks for a whole new generation of ultra-high resolution displays. ..."The main advantage of these displays is not only that they have ultra-high resolution, but also are solid state that can be put on highly flexible films," said team leader Harish Bhaskaran, a materials scientists at Oxford University in an interview with Yahoo Canada News. "Also, power consumption is low and in many respects it can retain the image until you go and change it, so no power is required when the image is static, unlike conventional screens that require refreshing," added Bhaskaran." via Yahoo! News

Why is Samsung the only one buying AMOLED displays? " ZDNet Korea did an interview with Samsung Display CEO Park Dong-Geun specifically on this topic, and he had a little more to say on it, specifically what Samsung Display is going to do about it. Park talked about Samsung’s current expansion into China and other markets where its devices are at saturation point, and would like to see expansion of its display division into these territories as well. Right now LCD is the most popular form of display on devices, particularly mobile ones, and Samsung wants to try to convince device manufacturers that AMOLED is the way to go, as they say it provides a richer user experience by giving the user better visuals. Right now they have to fight the fact that they are the largest consumer electronics company in the world, and as such many are likely choosing to support the underdog rather than the big dog." via AndroidHeadlines

How is Jaguar Land Rover enhancing the automotive display experience? "The car maker unveiled its 'Jaguar Virtual Windscreen' concept that uses the windscreen as a display to project information like racing line and braking guidance, ghost car racing and virtual cones. Jaguar Land Rover Research and Technology director Dr Wolfgang Epple said, "By presenting the highest quality imagery possible, a driver need only look at a display once. "Showing virtual images that allow the driver to accurately judge speed and distance will enable better decision-making and offer real benefits for every-day driving on the road, or the track." (Video)" via Automotive Business Review

How does new transparent touchscreen display work on both sides? "Their TransWall is not only transparent, but it can also receive input and display content on either side of its screen, plus it's capable of haptic feedback. The system is housed within a T-shaped frame that also incorporates two overhead-mounted projectors, which project visuals onto either side of the screen. That screen is made up of two sheets of plexiglass, with a clear holographic film sandwiched between them. Bordering those sheets are two rectangular infra-red touch sensor frames, one on either side. A surface transducer is also mounted in the plexiglass above the frames, plus microphones are integrated into each of them." via Gizmag

Waterproof, glare-free phone screens invented "The team at The Institute for Photonic Sciences in Barcelona, in conjunction with Corning Incorporated (the makers of the tough Gorilla Glass adorning many of today's premium smartphones) developed a novel technique of "roughing" the glass surface without sacrificing transparency. ...This discovery has strong implications for the mobile industry, where similar effects can only be produced by polarising filters placed over the screen. But these filters can interfere with the capacitive touch interface of many smart screens, a problem Pruneri's team believes may not be the case with their "roughening" method." via Wired

takee Holographic Handset Disrupts Traditional Technology "After 10 years of research and development, takee holographic handsets are taking the lead in handset screen display technology, making a disruptive breakthrough in the field. ...Something of note is that the takee holographic handset is fundamentally different from Fire Phone handset recently released by Amazon. Fire Phone's display technology is not a naked-eye 3D display technology, but rather employs Dynamic Perspective 3D technology, in actuality a form of 2D display technology. In other words, what one is observing is a dynamic expression of a traditional 2D handset instead of a visual display of holographic technology. In this regard, the takee holographic handset outdoes competitors by jumping ahead one generation." via Consumer Electronics Net

How is the digital signage industry being threatened? ""The industry faces tough competition from ordinary consumer television products that are being used by commercial establishments instead of specially outfitted digital signage displays, and the result is a loss for the signage industry as sales go instead to consumer-type replacements." Digital signage panel manufacturers and set makers can capitalise on existing advantages offered by the technology. These include high-brightness displays of 1,000 to 1,500 nits without compromising display lifetimes; ultra-narrow bezel displays for data visualisation; ultra-high-definition displays in high-end applications such as architecture firms and medical operating theatres; and touch, gesture or embedded vision for segments like education, for use in interactive whiteboards." via InAVate

Is the iPhone 6 Sapphire Crystal Display Really Unbreakable? Watch the Test "In an effort to test just how durable the suppose 4.7-inch iPhone 6 panel is, Marques puts it through a serious of gruesome tests, first by stabbing it with a knife, and then with a set of keys. He goes at it pretty hard, too—harder than your average phone would see on a daily basis—and the panel is essentially left unscathed. Even the sharp knife is no match for the sapphire crystal, inflicting zero damage. It’s incredibly impressive. Say good-bye to screen protectors once and for all. (Video)" via TechnoBuffalo

Does display form factor matter? "The way I see it, Google Glass is an early shot at making the computer disappear, at making it hide in the furniture. The true ideal form factor is one that isn’t there at all. It’s just a pure human interface. No friction. ...But even screen size can be handled as a relative matter. Apparent screen size is a function of distance between the viewer’s eyes and the screen and its actual dimensions. A 13cm (5.1”) screen held 60cm (~2’) away takes up the same field of vision as a 130cm (51.2”) screen at 600cm (~20’). You can watch a movie on a phone at two feet or on a big TV at 20 feet." via Forbes

Is the world finally ready for Virtual and Augmented Reality? "The year is 1979 and Richard Bolt, a student at MIT, demonstrates a program that enables the control of a graphic interface by combining both speech and gesture recognition. ...To this day, Richard’s research speaks to the core of what natural gesture technology aims to achieve, that “natural user modality”. While advances in HMI have continued to iterate and improve over time, the medium for our visual interaction has remained relatively intact: the screen. Navigation of our modern UI has been forced to work within the limits of the 2D screen. With the emergence of AR and VR, our traditional forms of HMI do not provide the same accessible input as the mouse and touch interfaces of the past. Our HMI must evolve to allow users the ability to interact to the scene and not the screen." via Games Alfresco

What's the Secret to Tackling Three Touchscreen Design Challenges? "The secret to achieving the low energy, high performance capacitive sensing is a hardware-based capacitive-to-digital converter (CDC). The CDC consists of two current digital-to-analog converters or DACs. The first is a variable DAC that delivers the current to the external sensor capacitor, and the second is a constant current source for an internal reference capacitor. Capacitance is measured using successive approximation registers (SAR) which is an efficient process immune to DC offset and requires no external components. The CDC improves accuracy and noise immunity by performing a two-stage discharge of the external capacitor to remove ambient noise energy captured during the discharge process. The CDC offers a wide dynamic range by adjusting gain and reducing source current to change the charge timing and more directly reflect the voltage at the capacitive sensor when the source current and series impedance are both high (i.e., such as when using a touch panel or ESD protected capacitive pads)." via Silicon Labs

How healthy is the medical imaging display market? "The worldwide market demand for medical imaging displays used in clinical review, medical diagnostics and surgical procedures, is showing strong growth, according to the new NPD DisplaySearch Specialty Displays Report. Between 2013 and 2017, global revenues for the displays used in surgical procedures and clinical review are each expected to grow at a compound average rate of 9%. Growth in diagnostic displays is forecast to increase 5% per year. ...The number of radiology investigations continues to increase annually, spurring growth in the diagnostic display market. The 21.3in display, now comprising 67% of the market, will continue to dominate this category. However, due to specialised panel and backlight requirements, few manufacturers participate in this niche market. Those that do participate have limited capabilities and some run on older, less-efficient production lines. Therefore, the costs to produce these panels are higher than the more commoditised displays, which results in relatively stable ASPs." via Installation

Pilot's Eye View of the F-35 Head-Up Display "The Rockwell Collins ESA Vision Systems F-35 Gen III helmet mounted display provides unprecedented situational awareness for pilots. AINtv spoke with F-35 Lightning II Chief Test Pilot Alan Norman about what makes this head-up display special. (Video)" via AINtv

Display Industry Trends – Survey Results "The two questions on laser phosphor projectors seemed consistent with what was discussed at Display Summit a couple of weeks ago. But nearly 1/3 don’t see the technology becoming a mainstream product, a bit higher than I would have expected. This probably means that lamp-based projectors will become value products - and there will continue to be a market for them. On the question of lumen output in 5 years, some are very bullish (17%) seeing the technology enabling projectors with over 35K lumens of light output. Many were unsure about this question." via Display Central

A Brief Rant on the Future of Interaction Design "In 1968 — three years before the invention of the microprocessor — Alan Kay stumbled across Don Bitzer's early flat-panel display. Its resolution was 16 pixels by 16 pixels — an impressive improvement over their earlier 4 pixel by 4 pixel display. Alan saw those 256 glowing orange squares, and he went home, and he picked up a pen, and he drew a picture of a goddamn iPad. And then he chased that carrot through decades of groundbreaking research, much of which is responsible for the hardware and software that you're currently reading this with. That's the kind of ambitious, long-range vision I'm talking about. Pictures Under Glass is old news. Let's start using our hands." via Worry Dream

Researchers make full-colour InGaN LEDs using LCD-type process "InGaN-based LEDs are now widely accepted as highly efficient light sources that can replace incandescent bulbs. But so far they been limited to small devices. Now a team from the University of Tokyo has shown that InGaN LEDs could form large area displays on amorphous substrates using a manufacturing technique frequently used for making liquid-crystal displays (LCD). ...By demonstrating that full-color LEDs can be fabricated on amorphous substrates, the researchers think that since sputtering is frequently used in the LCD industry, it could be adapted to fabricate large-area inorganic LED displays on glass substrates including flexible glass foils." via Compound Semiconductor

Chemists develop magnetically responsive liquid crystals "Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research opens the door to display applications relying on the instantaneous and contactless nature of magnetic manipulation—such as signage, posters, writing tablets, and billboards. Commercially available liquid crystals, used in modern electronic displays, are composed of rod-like or plate-like molecules. When an electric field is applied, the molecules rotate and align themselves along the field direction, resulting in a rapid tuning of transmitted light." via Nanowerk

Does Sharp's LCD plant revelation cast doubt on Apple's use of IGZO displays? "Osaka, Japan-based Sharp dedicates the entire production output of its Kameyama No. 1 LCD plant to Apple, Sharp senior executive Norikazu Hoshi told the Nikkei Asian Review last weekend. ...Apple has been rumored to be using IGZO technology — which broadly speaking allows LCD displays to let more light pass through, reducing power usage — for years, and was at one point said to have financed Sharp's retooling of Kameyama No. 2 with component prepayments. Instead, it is likely that the money went into retooling the No. 1 facility to produce LTPS panels, which are nearly as efficient as IGZO displays but easier to manufacture." via Apple Insider

Are 3D Displays Still Marching Forward? "Here in the United States many have become jaded about the future of 3D, but around the world it is booming. Last January, NechNavio, a technology research and advisory company, released a report predicting “the Global 3D Flat Panel TV market to grow at a compound annual growth rate of 15.4 percent over the period 2013– 2018. One of the key factors contributing to this market growth is the increase in 3D content broadcasts.” ...However, many potential 3D fans are still holding their breath until we can dump the glasses. Autostereoscopic (glasses-free) 3D flat panel displays, or AS3DTV sets, have been around for a considerable time and until now many, like me, have been skeptical about them. But during the 2008 3D BizExpo held at the Universal Sheraton in Hollywood, Philips Electronics took a major leap forward by introducing their WOWvx 3D system on a 56-inch Quad Full HD set." via TVTechnology

What Is Assertive Display Technology? Why Samsung Is Licensing It for Next-Gen Exynos Processors "Apical has been a leader in what they call ‘Assertive Display Technology,’ and Samsung has just licensed this technology to use with their next generation Exynos Processor, although we must point out the Qualcomm’s Snapdragon is also licensed for Assertive Display, so hopefully Samsung will use that technology on all of their smartphones. Assertive Display is an advanced display management core that will give the viewer a high-quality display even in bright sunlight and at the same time will lower the power consumption. This technology actually adjusts each individual pixel in real-time by using models of how the human eye responds to different viewing environments. " via Android Headlines

What Is the Best Tablet Display? Not the iPad "Based on our extensive Lab tests and measurements, the Galaxy Tab S is the best performing tablet display that we have ever tested, not surprisingly with performance that is almost identical to the OLED Galaxy S5 Smartphone that we recently tested and found to be the Best Performing Smartphone Display. The Galaxy Tab S establishes new records for best Tablet display performance in: Highest Color Accuracy, Infinite Contrast Ratio, Lowest Screen Reflectance, and smallest Brightness Variation with Viewing Angle. Both Galaxy Tab S models offer Quad HD 2560x1600 pixel displays (with 287 to 361 pixels per inch), currently the highest for tablets, with 4.1 megapixels, double the number on your HDTV. Where the Galaxy Tab S does very well but does not break performance records is in maximum display Brightness—the current record holder for tablets is the Nokia Lumia 2520 with 684 nits, while the Tab S has 546 nits with Automatic Brightness On and 415 nits under manual Brightness (10 percent lower for mixed content with 50 percent Average Picture Level APL and 25 percent lower for an all white screen). " via Gizmodo

How Are Augmented Reality Displays Getting Physical With Haptics? "From the lab to startup companies, the race is on adding physically perceptible volumes and textures to whatever is displayed on screen, ranging from a simple keyboard with a "click" feel to the complex rendering of 3D shapes and textures, either in volume or on a seemingly flat surface. The EuroHaptics 2014 conference, which took place in Versailles from June 24 to 26, was buzzing with actuators and haptic devices of all sorts. Well over a hundred papers, posters, and dozens of demos were presented, covering experimental research setups about human touch perception on one end, and various tangible haptic interfaces on the other end of the spectrum, with plenty of force and feedback encoding schemes in between." via EE Times

Why Will the Touchscreen Generation Forever Alter Tech Design? "Generation Moth will be fluent and fearless in a digitally mediated existence, where most of their analog needs are met with the help of digital services. They will use their bodies and all their senses as instruments for interaction, in a way that’s infinitely more varied and sophisticated than the touch screen paradigm we’re living in right now. As Generation Moth becomes influential across commerce and society, we will need to completely reimagine and reinvent the relationships that brands have with people. People-centered design will be a baseline, and the design of services that consider personalization, fluidity, predictiveness, and expressiveness will be key to success. This screen-addicted generation is going to massively change the way people live and attitudes towards the world, for generations to come." via Wired

How Are Touchscreens Adapting Game Designs? "The advent of touchscreen gaming left developers with a conundrum. Good platforming games depend on precise mechanical controls, like buttons, directional pads, and joysticks. Working around that limitation was a big challenge. ...Platform games evolved over 30 years from simple 2D affairs that took place on a single screen into full-blown 3D adventures in which you traverse graphically rich worlds. In the era of touchscreen devices like the iPhone and iPad, game designers have had to start from scratch, rethinking every convention of the genre. Leo’s Fortune sets a new bar for touchscreen platforming games, and like Badland before it, draws a blueprint for what may become the conventions of this new sub-genre. I’ll be interested to see if other game developers follow in Leo’s rolling footsteps or come up with entirely different approaches to working within the constraints of relatively small touchscreens." via TidBITS

Can a Safe Automotive Touchscreen Be Developed? "Google design manager Henry Newton-Dunn says the problem now is that cars are “fundamentally disconnected vehicles.” This leads many drivers to juggle their phones while driving—a bad idea, since the screens are too small and the interface and menus too complicated to navigate. “We had to take an experience that was designed for a smartphone and break it down to its bare essentials,” Brady says in the video, which shows drivers tapping on the screen to use Google maps and using voice controls to set reminders on their phones. Interest in smartphone design is hot, and as an extension, designing a smart screen for the car is getting hotter, too. Already, 28 carmakers in the Open Automotive Alliance are working with Android Auto. The problem is that while adding smartphone functionality to a car lets you do more while driving, safe driving generally requires you to do less. In other words, this problematic, dangerous behavior may not be something that can be designed around via a bigger, better device. Rather, the problem is that humans are not particularly good at multitasking. (Video)" via Bloomberg Businessweek

Are Virtual Reality displays a ‘game changer’ for the real estate industry? "Real estate technology expert, James Dearsley, of the Digital Marketing Bureau, tells OPP Connect, ..."Obviously putting people ‘inside’ apartments that don’t even exist yet is an amazing concept; giving them the ability to understand scale and depth whilst letting them navigate around an apartment is incredibly exciting. However, Virtual Reality is much more than that." ...Oculus has a huge outlet for its devices in Facebook and many other companies are lining up. Sony has Project Morpheus already in development as does Samsung with its VR HMD, says Mr Dearsley. “Then there are other, far smaller companies working on. A particular favourite of mine is Altergaze which recently went to Kickstarter for its first round of funding for its 3D Printed HMDs – these allow you to place your mobile phone into the device. Suddenly, the panoramas that you are producing through your phone can be displayed very differently." via OPP Connect

Pyramid-Like Arrangement Makes LEDs Brighter "According to the scientists at the University of Michigan, triangular phosphorescent organic light-emitting diodes (PHOLEDs) arranged into a pyramid-like structure shine three times brighter than a flat configuration of LEDs at the same current. “Achieving extra brightness from the conventional, flat design is inefficient and shortens the device lifetime,” said Jaesang Lee, a doctoral student in electrical engineering and computer science and first author of the study (see footnote). “However if we integrate our PHOLEDs into a pyramidal shape, we are able to achieve the equivalent, concentrated brightness at a much lower electrical current.”" via The Daily Fusion

Redefining Intelligent Display Implementation "Increasingly industrial control systems, domestic appliances, vending machines, point-of-sales units, security alarms and thermostats will start to rely on touch interaction. ...An example of a conventional intelligent display system is shown here. It has a high performance microcontroller – which is used to create and manipulate the graphic images pixel-by-pixel, a high capacity NAND Flash memory – for storing the graphics library, a large frame buffer – for driving the display, along with separate touch controller and an audio DAC. Wide parallel bus lines must be included to connect all of these devices together. This set up can prove to be totally impractical in many cases – presenting a sizeable bill of materials cost and a hefty power budget, as well as taking up a considerable amount of valuable board real estate. In addition, the system’s high complexity means that a considerable amount of technical know-how is called for. In response, FTDI has pioneered an innovative new solution that enables incorporation of intelligent displays into electronic systems in a far more streamlined manner, through employment of its highly-integrated proprietary semiconductor technology. The company’s award-winning FT800 Embedded Video Engine (EVE) is optimised for implementing high quality user interfaces on to QVGA and WQVGA displays." via FTDI Chip

Interactive Displays: Natural Human-Interface Technologies (Wiley Series in Display Technology) "The book will cover the technologies, applications and trends in the field of interactive displays, namely interfaces based on touch, gesture and voice and those using a combination of these technologies. The book will be split into 4 main parts with each being dedicated to a specific user interface. Part 1 'Touch Interfaces' will provide a review of the currently deployed touch-screen technologies and applications. It will also cover the recent developments towards achieving thinner, lightweight and cost-reduced touch screen panels in the future via integration of touch functionalities. Part 2 'Gesture Interfaces' will examine techniques and applications in stereoscopic 3D computer vision, structured-light 3D computer vision and time-of-flight 3D computer vision in gesture interfaces. Part 3 'Voice Interfaces' will review developments in voice input, processing and recognition techniques enabling voice based interfaces and interactions. Part 4 'Multi-Modal Interactions' will detail the emergence of natural human-computer interactions schemes which intuitively combine touch, gesture and voice for life-like interactions." via Amazon

What does the death of the CRT display technology mean for classic arcade machines? ""It’s just not gonna feel as nostalgic," Ware tells GamesBeat when we asked him about the problems with the modern display technology. "The pixels will be sharper on an LCD, but they may not be 100 percent accurate. Colors won’t be quite as vibrant.” Additionally, Ware explained that the refresh rate on an LCD may not play well with an old game’s code that is expecting a much more responsive CRT monitor. It could cause unsightly screen tearing that looks like one half of the screen is occasionally redrawing before the other. When the last major manufacturer stopped making CRTs, they sold the manufacturing equipment to a Chinese company that couldn’t properly reproduce the winding procedure. “Turns out that’s a semi-manual process,” says Ware. “You have to wind the CRT bulbs by hand, so they stopped making them. I have an engineer on staff that couldn’t do it. I couldn’t do it. It’s almost an art form."" via VentureBeat

Shenzhen Immigration – Another good reason to talk to us about your LED display screen FAT inspection "Ever arrived in Shenzhen late in the week to inspect your order only to be wined and dined, and then to learn you have to extend your stay for an unplanned weekend ‘holiday’ in Shenzhen because your product will not be ready on time? It happens and unfortunately more often that you might expect, but the high cost and inconvenience of international travel arrangements and manufacturing delays are not the only reasons to speak with us about your LED display screen FAT inspection. With 17 years experience in the manufacture of LED display screens, and over 10,000m2 of product shipped we have inspected literally hundreds of screens. We know what to look for and can often help to analyze and suggest solutions when issues are found." via Bateman Consulting

How to Design Capacitive Touch Sensors using MBR in 5 Easy Steps "Traditional user interfaces are designed with mechanical buttons which can be unreliable, bulky, and unattractive. Capacitive buttons have begun to replace mechanical buttons, which blend into the product design and never wear out. Capacitive touch sensing solutions are the trend in user interfaces design. However user interface design with capacitive buttons is not easy. It's often a laborious task for system engineers to implement a robust solution. This paper will focus on how to easily design capacitive touch sensors with MBR devices." via EE Times

Why capacitive touchscreen panel suppliers are boosting production capacity "By year-end, the capacitive segment’s share of total touch panel deliveries from China is projected to surge to 73 percent from 54 percent in 2013, according to IHS Displaybank. Of this, smartphones will account for as much as 84 percent. In terms of output, the country’s aggregate volume reached 780 million panels last year based on TPTech’s statistics, and 540 million units went to the handset sector. Local makers are also eyeing spreading adopt ion of touch technology in notebook computers. Enabled units stood for 11 percent of total worldwide shipments in 2013 and may have a ratio surpassing 40 percent by 2017, presenting more opportunities for the line." via Global Sources

Empirical Development of Heuristics for Touch Interfaces "While touch interfaces were previously in common use only for entertainment and social networking apps, many large software firms are now designing touch interfaces for mobile apps that provide extensions to enterprise software, giving customers access to functionality that had previously required them to be on a Web site or application. Because the functionality of these apps tends to be complex, having a practical, reliable usability evaluation method for touch mobile interfaces is vital. ...In this article, we have described our empirical approach to verifying existing design heuristics and developing new heuristics for touchscreen devices. The marked differences between our findings and those of previous studies of desktop design heuristics suggests that we need to re-evaluate traditional heuristics when approaching the evaluation of touch interfaces." via UX Matters

Insane Tablet and Phone Touchscreen Repair Tips You Should Avoid "The author correctly notes that using Turtle Wax will remove the oleophobic coating on modern touchscreen devices. Oleophobic coating is an oil-repellent coating that repels the oils on your fingers and helps reduce unsightly smudges. Removing the coating means your phone will pick up more oil and smudges. So, how do Turtle Wax and other “scratch repair kits” designed for cars work? Most of these scratch repair kits are intended for metal and paint problems, not even the glass windshields or windows on a car! Turtle Wax does offer an “intensive cream glass polish” product that “uses ultra-fine particles to remove ingrained dirt, light scratches, and wiper haze from windscreens.” In other words, Turtle Wax and similar products work by removing the top layer of your phone’s touchscreen display. This is basically just like using sandpaper." via MakeUseOf

How will Sharp's free-form display affect design? "The electronics maker has announced a prototype Free-form Display that can be made in whatever two-dimensional shape is required. Potential applications include dashboard displays incorporating multiple circular contours, wearable computers with elliptical screens, tablets and smartphones without frames, and complex digital signage. Instead of incorporating the gate driver on the perimeter of the display, the Sharp prototype disperses its function throughout the screen’s pixels. The bezel, or area that surrounds the screen, can thus be shrunk. While it’s not the first non-rectangular LCD screen, Sharp’s prototype is the first thin-bezel LCD that allows for various screen shapes, the company said." via PC World

Samsung's $1 billion LCD plant in Vietnam "In 2009 Samsung inaugurated its mobile phone production plant Samsung Electronics VN in the northern province of Bac Ninh. The plant had an initial investment of $670 million, which eventually increased to $2.5 billion. Four years later, the $2 billion Samsung Electronics VN Thai Nguyen complex broke ground in Thai Nguyen, another northern province. Around 43,000 employees are working at the Bac Ninh facility, and the Thai Nguyen complex is expected to attract up to 50,000 workers. It is estimated that Samsung’s two plants in Vietnam will produce $35 billion worth of mobile phones this year." via Tuoi Tre News

Are Samsung’s New AMOLED Tablets Better Than Their LCD Tablets? "Samsung will certainly be preaching about the advantages of its AMOLED display – take a look through some of the photos in the gallery and you will see that when it comes to Color Reproduction, using the Adobe RGB Gamut that the AMOLED display captures 94-percent and the LCD only 74-percent. When it comes to Contrast Ratio, you can get 100,000:1 versus 1,000:1 on the LCD display. This higher Contrast Ratio offers more vivid – jump out at you – colors and deeper blacks than the LCD technology can provide. Many users have complained that the AMOLED display does not faithfully reproduce the colors of the original image, while AMOLED supporters say they enjoy getting a more attractive display experience." via AndroidHeadlines

What is AU Optronics' place in the display industry? "It wasn’t until the mid- to late- 2000s that LCD displays swamped the consumer electronics market. Suffice it to say, they’ve had an incredible impact in a short time. As such, AU Optronics has similarly high impact in the industry...although few seem to know it. The company makes both LCD and AMOLED displays with its thin-film transistor (TFT) technology. Each display works differently, and with consumer demand for both, AU Optronics is satisfying that demand. Its Hyper-LCD displays offer even greater viewership through “Advanced Hyper-Viewing Angle” (AHVA) technology, which gives flawless picture quality, even at various angles. But its AMOLED technology is really raising the bar." via Trefis

How does Amazon's Fire Phone create a 3D multi-perspective display? "Amazon's finally unveiled its first smartphone: the Fire Phone. And, as expected, there are 3D-like features on board, with something the company's calling Dynamic Perspective. ...Bezos said during the presentation that getting Dynamic Perspective ready for everyday users wasn't easy. "The key is knowing where the user's head is at all times," he stated, citing the need to have multiple cameras (remember those?) on the Fire Phone to make the feature work properly. In total, the device has six cameras -- four of which have a 120-degree field of view and are used specifically for Dynamic Perspective, plus your usual front and rear shooters." via engadget

How is Corning's anti-reflective display coating revolutionary? "The anti-reflective coating needs to be applied to both sides of the display and will drop the reflectivity of the screen from standard 8% to mind-boggling 1%. The coating which is applied using Zero Air Gap technology reduces reflection as you can see from the video below. ...The coating improves contrast and outdoor readability from 40% to a staggering 123%. There is a 90% reduction in reflectance, while the display will deliver 3X more colour in outdoor situations. (Video)" via Techtree

Could virtual reality displays be made consumer-ready with eye tracking? "Kreylos explains that the distance between your pupils is not always constant, and human eyes will occasionally swivel inward to make the light from a perceived object precisely hit the high-resolution fovea on the eye's retina, depending on how virtually “far away” an object is. Kreylos explains that your eyes can “swivel in” if the screens are displaying something particularly close to you in the virtual space (like when you would bring a finger to your nose to go cross-eyed as a kid), and that can cause nausea without eye-tracking because the image projected by the Oculus will appear distorted as well." via Ars Technica

Bosch introduces “combiner” head-up displays for BMW "The combiner system merges the images that are generated by the car’s instrument panel with the scenery outside and makes the combined picture look as if it is two meters in front of the vehicle. The information isn’t projected on the windshield but is displayed on a small plastic screen placed just before it. The technology can be fitted to various types of car models without any major technical modifications. Bosch said the new type of head-up display provides easier visual access to the information because a driver doesn’t have to refocus as much as with conventional systems." via automotiveIT

LG Loses Exclusive Supplier Contract for Apple's In-Cell Displays "To save face, LG is now saying that they had been experiencing numerous limitations bound by an agreement for exclusive supply right with Apple, which holds a number of patents. LG Display can now broaden the scope of its movements as the exclusive supply agreement has expired recently and it has secured "Advanced In-cell Touch (AIT)" technology to avoid limitations imposed by Apple's patents. The report further noted that LG Display developed AIT to circumvent Apple's patents. The biggest difference between AIT with In-cell touch display for Apple is that it is applied with self-capacitance technology, which evolved from the conventional touch type to an individual recognition of the fingers touching the display. Apple has adopted mutual-capacitance technology to concurrently recognize a multiple number of fingers." via Patently Apple

When a brand name outlives its founding technology: PureView and CBD "One of the most frustrating things about marketing and branding, from my engineer's standpoint, is that technologies get brand names assigned to them (which is fine) and then the brand name gets used elsewhere, for something totally different. ...Now, Nokia owns the 'brand' here. If it (or, in this case, now Microsoft, I guess) wants to use 'ClearBlack Display' to refer to a simple lamination then that's absolutely its perogative. Heck, Nokia could use CBD branding on a toaster if it liked - it can do what it likes with its own marketing brand. But it's the changing definition that leaves technologically-minded users confused. Even more so because the new 'definition', an ambiguous 'aim', has been applied in a device with definitively worse outdoors performance. The PureView change was at least a totally different direction that was intended to be folded into the original tech in the future. This 'ClearBlack Display' definition change just muddies the waters, in my opinion." via All About Symbian

Is OLED Dead? "UltraHD sets were once again everywhere at CES 2014, while OLED had a lower-profile presence. Most of the OLED TVs were curvy this year. Some could even transform from flat to curved. They all looked good, but the novelty of seeing UltraHD sets and OLED sets had largely worn off. It was the third straight year they were on display at CES. Instead, the most interesting developments at the show involved dramatic improvements in LCD picture quality. Advancements in LCD panels are closing the picture-quality gap between OLED and LCD—and the latter are much more affordable and cheaper to produce." via Wired

Why is AUO no longer merging with Innolux? "Taiwan's Ministry of Economic Affairs has given up plans to have domestic flat panel makers AU Optronics (AUO) and Innolux merge due to a disagreement on the leadership after the merger, our sister paper Commercial Times reported on June 17. ...Officials said that the ministry's research predicted potential for 15% growth for the country's flat panel sector after the merger. Yet now that the two companies have worked out debt repayment plans with banks, the merger plan became less important for both, as they have received more orders over the past few months." via WantChinaTimes

Will Taiwan's flat panel display industry be overtaken by rivals? "Taiwan's flat panel display exports to China have lagged behind South Korea for the fifth consecutive year. The island fears it will lose more market share to its rivals, especially after Seoul and Beijing complete their free trade deal at the end of the year. Taiwan was once the world's biggest flat panel display supplier to the greater China market. Between 2003 and 2008, Taiwan held more than 35 per cent of the Hong Kong-China market. But while Taiwan sat on its laurels, China and South Korea started cranking out flat panels." via Channel NewsAsia

What new high-quality polymer could be used for LCD glass? "Asahi Kasei Chemicals has developed new transparent polymer for high performance optical applications, which is now ready for commercial production. The material called AZP offers zero birefringence by using novel molecular design.

SID Applauds Winners of Display Industry Awards "The Society for Information Display (SID) celebrated the winners of the Display Industry Awards, Display Week Best in Show and I-Zone during its annual Awards Luncheon yesterday. This year’s winners include: 2014 DISPLAY INDUSTRY AWARDS Display of the Year: Granted to a display with novel and outstanding features such as new physical or chemical effects, or a new addressing method." via Display Central

Could Touchscreens Be Reinvented By This Tiny Startup? "Qeexo is hoping to emulate Steve Jobs. Backed by $2.3 million, the San Jose, California-based startup has developed a new touchscreen technology that can detect the difference between a fingertip, a knuckle, a fingernail, and a stylus. By assigning different parts of the finger to different actions, this technology–known as FingerSense–could reduce tasks that currently require multiple steps to just one. “You can imagine it’d be like having different buttons in your hand,” explain’s Sang Won Lee, the company’s co-founder and CEO. The iPhone, and indeed the entire smartphone industry, have evolved dramatically since that day in 2007. And yet, for all the features that have been tweaked and perfected over the years, the language Jobs taught us has remained unchanged. We still use a single input–a fingertip–to operate the device. And that limits the way we use our phones. " via Wired

Will Touchscreens Soon Be Shatterproof? "That heartbreak may be a thing of the past due to research out of the University of Akron: a new transparent electrode material that makes the screen virtually shatterproof. There has been a huge push in nanomaterial research with the aim of finding a replacement for indium tin oxide (ITO), which is the material from which transparent conductors that control screen pixels are made. One of the problems with ITO is that it’s a relatively scarce resource, and with the market for tablets and smart phones exploding, that scarcity has become more acute. This market shortage, combined with the brittleness of ITO-based screens, explains why a variety of nanomaterials have been given a “market pull” opportunity rather than merely a “technology push” prayer." via IEEE Spectrum

TFT displays can be cut to size "TFT displays of a custom size, and optically bonded displays for example, are becoming available with initial non-recurring engineering (NRE) charges a fraction of those associated with a full custom display and the minimum economic order is low. For example, designers everywhere are keen to eliminate drab LCD character modules from their systems and replace them with colour graphic displays, often including touch control. However, TFT displays are made in standard formats and until now, the cost of manufacturing a custom size has been uneconomic for most industrial applications. Manufacturers now have flexible processes which make it is possible to cut standard small format TFT displays to a specified height, opening up new application areas." via Electronics Weekly

How to implement haptics in touch-based user interfaces "Transitioning from mechanical buttons, knobs, and dials to a capacitive touch interface, however, poses a challenge to designers because there is no tactile feedback present with capacitive touch sensors as exists with mechanical buttons and switches. For example, consider the experience of typing on a keyboard. When a key is pressed and released, it bounces back due to spring action. A person can feel the force of the key bouncing back with his or her finger and thereby confirm the key press. With a capacitive touch interface, there is no inherent mechanical feedback, and users do not have the same experience as that of mechanical keys. The absence of tactile feedback poses a challenge to designers in that their primary goal is to improve user experience. Through haptics technology, developers can provide tactile feedback, improve the user experience, and add value to products." via EDN

Is thermal touch a new interface option? "We’ve been conditioned as technology users to look for touch -- it’s really the default user interface for most technology now. Wearable device makers have proposed multiple interface solutions: voice navigation, depth tracking for finger detection, companion devices, and even things as novel as shoulder-mounted projectors. Though these options are a great start, we’ve found many of them lacking, or even, frustrating for the average user. But what if we could turn any surface into a touchscreen? This was the idea we tasked ourselves with after discovering the potential gain in marrying thermal imaging with traditional computer vision algorithms. Our mobile prototype runs on a Lenovo ThinkPad tablet PC, to which we attached a combined thermal and visible light camera module. The fixture is simply a joist hanger I purchased at a local hardware store. (Video)" via EE Times

7 Futuristic Display Interfaces from MIT's Media Lab "Any design nerd, futurist, or techie worth his weight in salt has heard of the MIT Media Lab. Few, however, have heard of the Fluid Interfaces Group. No, it’s not a smooth jazz outfit—it’s a division of the famous Media Lab, and home to some of the niftiest display prototypes and interface designs this side of the Mississippi. ...Fluid has been around for at least seven years, but recent advances in mobile, sensor, and display technology seem to have inspired a wealth of breathtaking new projects. Here are seven recent ideas that offer a glimpse at the future of interface technology." via Reviewed.com

Where are cockpit displays headed? Q&A with cockpit manufacturer Continental "By just looking at a 10 year old cockpit, we would immediately see what is expected nowadays for a mid-range segment: it has to look high tech with a full colour TFT [thin film transistor] display in the cluster as well as in the centre stack. For the secondary display, touch functionality is becoming the norm. It has to be connected to your smart phone - USB, BT, mirror link - and include a lot of sensors mainly related to safety such as rearview camera, rain detection and park assist. With the increasing number of functions in the car, ease of use is becoming more and more important. So, a well structured HMI [human machine interface] concept is required." via just auto

Google Glass Enters the Operating Room As Medical Display "The Glass projector is slightly above the user’s right eye, allowing doctors to see medical information without turning away from patients. But the display can also be used to see email and surf the web, potentially allowing doctors to take multitasking to dangerous new levels, said Dr. Peter J. Papadakos at the University of Rochester Medical Center, who has published articles on electronic distractions in medicine. “Being able to see your laparoscopic images when you’re operating face to face instead of looking across the room at a projection screen is just mind-bogglingly fantastic,” he said. “But the downside is you don’t want that same surgeon interacting with social media while he’s operating.”" via The New York Times

Will next-gen smartphones have sensors built into display glass? "Corning International, which makes the material commonly used in mobile device screens, has teamed up with researchers at Polytechnique Montreal to create a new type of glass that incorporates transparent sensors. Soon, the glass in your smartphone screen could be used to take your temperature, among many other possibilities. The team used lasers to carve photonic waveguides into regular Gorilla Glass, at varying levels within the thickness of the glass. Each one of these acts as a tunnel, which photons can travel through in the same way that electrical currents flow through copper wires." via gizmag

Are 3D holographic displays on their way? "Carlsbad, Calif.-based Ostendo Technologies is readying a potentially game-changing technology that may make its way into upcoming generations of connected gadgets. In such a scenario, visuals can be rendered three-dimensionally, as holograms. This means that tedious tasks, such as shopping for a couch on your smartwatch, would be made easier with the option of beaming up life-sized replications. ...An industry veteran and the former chief executive of mobile chipmaker CommQuest, Hussein S. El-Ghoroury has spent the last eight years homing in on a way to shrink the entire process down to a circuit the size of a piece of chewing gum. He made his first breakthrough using a technique that allowed silicon to effectively bond with light-emitting diodes, which he compares to mixing oil with water." via The Washington Post

Miyamoto Interested in Virtual Reality, But Sees a Conflict With Wii U ""We've been doing our own experiments with virtual reality dating back to the Virtual Boy," he said, referencing Nintendo's failed VR system released in 1995. "And even to some degree, the 3DS was designed with a little bit of this in mind with its stereoscopic 3D. So we're always looking at hardware and assessing what's possible." He pointed out that, while the price of VR has begun to drop, "It's still not at a cost basis that makes it easy for everyone to purchase as a mass-market product." "As game designers, we at Nintendo are interested in VR technology and what it can do, but at the same time what we're trying to do with Wii U is to create games for everyone in the living room," he continued. "We want the Wii U to be a game system that brings video gamers into the living room."" via Gamespot

Manufacturing: The forgotten industrial digital signage application "Imagine an industrial plant where management wants to communicate vital information to hundreds of workers. Perhaps it's production quotas vs. actual performance; perhaps it's mean time between accidental employee injuries; perhaps it's delivery information regarding vital components that are en route. In all of these instances — and others too numerous to recount here — digital signage has the ability to convey to a workforce important information that is vital to employees maintaining a safe, efficient environment. Digital signage for manufacturing is an excellent reminder that ROI can occur in so many ways; let’s not forget it when we figure ROI for any industry." via Digital Signage Today

Sony Delivers Immersive Keynote at SID Display Week 2014 "At SID Display Week 2014 in San Diego, CA, USA on June 3, Sony executive Dr. Kazumasa Nomoto delivered an opening keynote address that laid out the firm’s view of the future for their display products. Dr. Nomoto chose to frame his presentation around the immersive nature of the display viewing experience using the term “Immersiveness.” The presenter identified the factors influencing display immersiveness as Resolution (4K/8K), Size, Wide Color Gamut (WCG), High Dynamic Range (HDR), and High Frame Rate (HFR). For example, he cited the effect of high display resolution on Immersiveness contrasting a 2K (1920×1080) HD display viewed at a distance of 3 screen heights resulting in a 30 degree display field of view with the more immersive viewing experience resulting from viewing a 4K (3840×2160) 4K (UHD) display viewed at a distance of 1.5 screen heights yielding a 60 degree field of view. Both distances correspond the the minimum distance to not see pixels." via Display Central

How Did Oculus Rift Make Virtual Reality Real? The Inside Story "But even these couldn’t give Luckey the immersion he craved. When he put them on, he felt like he was looking at a play space, not living inside of it. “It wasn’t garbage,” Luckey says, “but it wasn’t virtual reality.” The image quality was poor, because the transmissive LCDs weren’t high-contrast. The head-tracking latency was off the charts, causing a nauseating lag every time he turned his head. But most of all, the field of vision was too narrow. He could always see the edge of the screen, which meant his brain could never be truly tricked into thinking it was inside the game. Luckey figured that he had as good a chance as anyone to solve those problems. So he tinkered, and tinkered some more, and one night in November 2010 he announced to the world—or at least to the message-board denizens of a 3-D-gaming news site called Meant to Be Seen—the existence of PR1 (for Proto­type 1), his first stab at a virtual-reality device. It was a cumbersome beast, built on the shell of a headset from his collection. It displayed only in 2-D and was so heavy that it needed a 2-pound counterweight in the back. But thanks to a massive chassis that could fit a nearly 6-inch display, it boasted a 90-degree field of vision, an angle nearly twice as large as anything else on the market." via Wired

How Can New Transistors Bring Flexible Screens Closer to Reality? "The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. Last year, Samsung even unveiled a smartphone with a curved screen, but it was solid, not flexible; the technology just hasn’t caught up yet. But scientists got one step closer last month when researchers at the U.S. Department of Energy’s Argonne National Laboratory reported the creation of the world’s thinnest flexible, see-through 2D thin film transistors. These transistors are just 10 atomic layers thick--that’s about how much your fingernails grow per second." via PCB Design 007

Tribute for liquid crystal display pioneer "Mathematician Frank Leslie, who died in 2000 aged 65, developed a theory of liquid crystals while working at the University of Strathclyde. ..."Engineers use the Ericksen-Leslie equations to optimise their flat-screen displays, making them thinner, faster and higher resolution. "Chemists use the Leslie viscosities to help make new improved liquid crystal materials, which can be used for both displays and for other applications, such as in biology. Professor Leslie's research is so influential that if you look around, you will probably spot at least one screen - maybe the computer screen you have on your desk or the mobile phone in your pocket - that has been developed with the aid of his equations."" via BBC News

Industry's first non-ITO film-based 42" display "The module was built by Amdolla Group, a leader in advanced touch module manufacturing, using Cima NanoTech's highly conductive, silver nanoparticle-based, SANTE® FS200 touch films. ...With a scan rate of 150hz for 10-point multi-touch, rivaling the response time of smartphones and tablets, this jointly developed product dramatically increases the speed of large format touch displays. Unlike optical and infrared touch solutions, this module does not have a raised bezel for a smooth cover glass. In addition, the random conductive mesh pattern formed by SANTE® nanoparticle technology eliminates moiré, a challenge for traditional metal mesh technologies, thus enabling touch screens with better display quality." via Printed Electronics World

Medical Imaging Display Market Shows Robust Growth "In the surgical display market, larger screens with higher resolutions are becoming more common and affordable and many are already being installed in surgical rooms, as collaboration among medical professionals, both on-site and virtual, becomes more popular. ...In addition, several key trends in the flat panel display market, including the shift to LED backlights, large, high-resolution 4 MP and 6 MP displays that can be split, color displays that can accurately show both color and grayscale images, and the wide availability of 4K displays, is expected to have different impacts on the various segments of the medical imaging market." via eWeek

How does oleophobic/hydrophobic coating enhance display glass durability? "Abrisa Technologies introduces CleanVue PRO™, a severe abrasion resistant oleo/hydrophobic coating that repels dirt, dust, water, grease and oil, enhancing display glass performance and longevity. This protective coating is well-suited for high performance anti-reflective (AR) coated cover glass for displays used in high contrast, heavy use and/or harsh environments. The resulting coated surface is easy-to-clean and maintain, does not stain, allows repeated removal of fingerprints, all while maintaining its anti-reflective properties. CleanVue PRO™ is ideal for protective vehicular instrument control panels and devices, field use touch and display panels, projected capacitive (PCAP) and capacitive touch screens, portable handheld devices, teleprompters, virtual reality applications, in-flight and vehicular entertainment screens and a host of other display devices." via ThomasNet

Will the Demand For Higher Generation Glass Substrates Drive Corning’s Display Volumes? "Glass substrates are manufactured in different sizes which are indicated by the “Generation”. Higher Generations have a larger area. Display panel manufacturers prefer higher Generation glass,specifically Generation 8, since it is much more economical. In the third quarter of 2010, 41% of LCD TV panels were produced using Generation 8 LCD glass. By third quarter of 2013, the number increased to 87%. Additionally, with improvements in glass manufacturing process, higher Generation glasses are becoming thinner and lighter and can be used to produce display panels for a variety of other devices, such as smartphones and tablets. In the third quarter of 2010, the use of Generation 8 glass substrates was limited to LCD TVs and monitors. However, by the third quarter of 2013, Generation 8 glass substrates received acceptance in display panels for notebooks, tablets and smartphones, albeit accounting for a small proportion. The over demand for Generation 8 glass substrates is expected to increase 3% by the third quarter of 2014." via Trefis

Will Sony and Panasonic form OLED Display Panel Collaboration With Japan Display? "Cracking the cost formula for big OLED TVs is still a challenge for the industry as a whole, but Japanese manufacturers hope they may still have chance to compete against South Korean rivals in smaller-size panels through a three-way tie-up, one of the people said. Japan Display, owned around 35% by a government-backed fund, is the world's biggest maker of smartphone and tablet displays and has a pilot line at its plant to develop OLED screens. Having listed its shares in March, the company itself was formed two years ago through a merger of the LCD units of Sony, Hitachi Ltd. and Toshiba Corp." via The Wall Street Journal

Why Did Samsung Blow Large Screen Smartphones? "A recent Canalys report noted a trend showing demand for larger displays shifting to premium smartphones. But, despite the company's dominance in the large-screen smartphone category, Samsung may be missing the boat. In Samsung's most recent quarter, the company reported slowing demand for its premium smartphones. And despite increases in total smartphone shipments, profits for the company's mobile business actually declined. What Samsung failed to realize: When larger displays are reserved for premium devices, the high value of the feature can be used to support a company's premium pricing tier and help buyers quickly identify a company's flagship products." via The Motley Fool

Can augmented reality be made more comfortable? ""Minimizing visual discomfort involved in wearing AR displays remains an unresolved challenge," says first author Hong Hua of the University of Arizona. "This work is making a significant step forward in addressing this important issue." A lightweight, compact and high-performance Google Glass-like device-called an optical see-through head-mounted display (OST-HMD)-could potentially be "a transformative technology to redefine the way we perceive and interact with digital information," Hua says. For example, it could one day allow a doctor to see computed tomography (CT) images overlaid on a patient's abdomen during surgery or provide a new way to train soldiers by incorporating 3-D virtual objects into real-life environments." via Space Daily

'Thermal Touch' Tech Turns Any Surface Into a Touch Screen "Sure, wearable headsets are practical and fun, but are they reaching their full potential? Not according to augmented reality firm Metaio, which this week unveiled a thermal imaging system for use in AR headsets. The company's initial Thermal Touch prototype attaches infrared and standard cameras to a tablet, which then tracks the heat signature left behind when you touch a surface. Still about five or 10 years away from hitting the market, the technology will eventually focus on heads-up displays (HUDs) or interactive spectacles. (Video)" via PC Magazine

Taking touchscreens into the third dimension "While some end users will continue to prefer designs with buttons and knobs, touchscreens have become sufficiently robust and low cost to make them a viable alternative. ...Microchip has taken it to a new dimension. Literally. Using its GestIC technology, user interfaces can be taken into the third dimension, allowing gesture recognition at distances of up to 15cm from the sensor. The chip containing the GestIC technology is the MGC3130, which features a low noise analogue front end, integrated digital signal processing unit, frequency hopping against noise and recognition of XYZ positional data – most specifically hand gestures. "There is also preprocessed gesture recognition [on the chip]," said Duvenhage. "You could do normal waves in specific direction, or you can do more complicated gestures, like a circle or the equivalent of what we call an 'air wheel' where you can adjust something by rotating your hands clockwise or counterclockwise."" via New Electronics

How can military augmented reality displays be commercialized? "ARC4 isn’t a pair of sci-fi glasses; in fact, it’s not a hardware system at all. Rather, it’s is a software system that accepts inputs from a sensor module made of cameras, satellite information, and head tracking technology, and fuses it all into a display that can be overlaid onto someone’s field of vision. Functionally, the end product makes walking around look a lot like playing a first-person shooter game like Halo. In the military, it provides real-time information to soldiers about their environments, even if their vision is obstructed. ...In a military setting, ARA has used hardware like BAE System’s Q-Warrior display—a large, expensive device that fits in on the battlefield but never takes off in a store. But the ARC4 systems don’t have to be installed on huge devices, says Allan York, ARA’s senior vice president. “Essentially, in a package the size of a sugar cube, you can have the sensing components necessary.”" via The Daily Beast

Is hologram-guided heart surgery a heartbeat away? "This proprietary digital technology from RealView Imaging in Yokneam projects hyper-realistic, dynamic 3D holographic images of body structures “floating in the air” without the need for special glasses or a conventional screen. The physician can literally touch and interact precisely with the projected three-dimensional volumes, providing an unprecedented tool for planning, performing and evaluating minimally invasive surgical procedures. Cofounder Shaul Gelman explains that the breakthrough technology can be summarized as very rapid printing of light in free space. The system is fed with data from standard medical imaging sources, such as ultrasound." via Israel21c

WORM display lets you write with light "Scientists at Universiti Malaysia Pahang (UMP) have developed displays that can be written on and erased with light. The WORM (Write Once Read Many) display is an optical storage device whose molecular geometry can be altered by shining light on it, allowing information in the form of words or pictures to be impressed on it in as little as 20 seconds. The environmentally-friendly display is also easy to dispose of, the researchers report, as users only have to scratch its surface to remove its protective coating and dip it in water to dissolve it. The displays are created using highly photosensitive compounds and can be written on using ultraviolet (UV) light. To fabricate the display, the researchers mix the compounds with liquid crystals and create two substrates. Transferring information involves placing a photo mask containing the data on top of the second substrate and exposing it to UV light with a wavelength of 365 nm." via Gizmag

A Crazy Levitating Display, Made With Particles and Projectors "Pixie Dust, as the team is calling it, builds on their previous system, which used a four-speaker array to summon objects into the air and move them around in three-dimensional space. ...Projection-mapped particulate ghosts are likely still a ways off. Still, the demos here are a fine holdover–and a reminder that our the possibilities of next-gen displays extend to far more than pixels trapped in a frame. (Video)" via Wired

Tactile touch technology "A conventional tactile touch system (e.g., smartphones) presents the same sensation over the entire surface so that all fingers coming into contact with the surface experience the same sensation. In contrast, the new NLT tactile touch technology provides regional stimulation, which is provided by electrostatic force. The electrostatic force is generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents tactile sensation to the users. The tactile touch technology applied to the panel provides multi-finger interaction." via SPIE

Display panel makers steaming ahead at full capacity "Industry research institute WitsView recently stated that a momentous boom is poised to carry the panel-making sector through the third quarter, straining production at near capacity. According to the institute, the display panel industry is in the early stages of a transition toward newer product specifications, resulting in strained production output as companies work toward improving manufacturing yield rates and materials consumption efficiency. In addition, the rise of new panel specification is expected to divert limited production capacity from more conventional display panel formats and constrain supply." via The China Post

Could Apple use solar-charging touchscreens on future iPhones, iPads, or iWatches? "The new patent describes a “solar cell stack-up configurations” that includes one or more touch sensor layers and one or more solar cell layers. ...“Using solar cells on portable devices, particularly handheld portable devices with small form factors, however, poses certain technical and/or design problems. For example, the small size of the portable device means there is a small surface area which can be used for placing solar cells. This surface area is typically further reduced by other components that appear on the surfaces of the devices such as input devices and display devices. Since the maximum solar energy that can be produced from a solar panel is roughly proportional to the surface area of the solar cells, this reduces the amount of solar energy that may be gained from the solar panel,” the patent read." via Digital Trends

Will ITO disappear as a display manufacturing material? "Similarly, we all know about indium tin oxide, the transparent conductor commonly known as ITO, and the crucial role it plays in LCD manufacturing and in touchscreens. Some estimates say that more than 80% of indium use is in these applications, and the stuff is used in other areas such as solar PV arrays, too. I’ve heard a few voices that say the price will just continue to rise and rise, and companies will be lucky to get enough to make their screens. They may want to pause to draw breath. Companies like Kodak and Cambrios have been working on the printing of very fine silver wires. By fine, think much thinner than one micron. Because of the conductivity of silver, this still works in carrying sufficient current to an LCD pixel or identifying location on the surface of a touchscreen. ...This doesn’t mean that ITO use will be eliminated. Indium is a by-product of zinc production, by and large, and so the price could likely drop a long way before hitting negative gross margins. That means the cost of ITO can also drop a long way. It seems likely that silver wires and ITO could share the display and touchscreen markets, maybe with silver wires dominating in areas where power consumption is critical. But the idea that indium price and demand will just continue to rise indefinitely is likely wrong." via InvestorIntel

How the US Navy Is Pushing the Touchscreen Envelope "The Navy will soon field its first 3-D Weapons Launch Console Tram Trainer at the Submarine Training Facility in Pearl Harbor, Hawaii. ...The screens — some up to 55 inches — are not just touch-sensitive but pressure-sensitive. There’s no mouse-clicking to make things happen; sailors are expected to reach out and “grab” the objects they want to manipulate. ...In fact, this simulator is pushing the state-of-the-art in haptics, or tactile feedback, and is helping to move the simulation industry itself to a new level." via DefenseNews

Automotive Displays: Visteon OASIS Cockpit Concept "Optimized. Adaptable. Secure. Intelligent. Seamless.

Why mobile and touchscreen HMI are the future "Concurrent with the trend to consumerize HMI, we're seeing an increase in mobilized HMI. Not surprisingly, given all these new devices connecting to the plant, security is becoming an issue. Other HMI trends include TVized large flat screens, increased use of thin clients, a broader view of data on the screen, and everything HMI coming at a cheaper price. ...Another aspect of HMI attractive to young engineers is TV-like screens. "We have graphics on 19-inch monitors that can be used on the machine. It's not a touch panel, but most shop guys don't like touchscreens," Randy Pearson, international business development manager at Siemens, said. "Touch is still new to all of us. Newer and younger engineers will bring touch in, and then it will be prevalent."" via Design News

How Polaroid used LCD technology to avoid becoming irrelevant "Polarized technology, which was invented by Polaroid Founder Edwin H. Land was first used in goggles supplied to World War II pilots and has since been used in nearly every aspect of visualization, including the polarized sunglasses we wear today. ...With these three traits in mind: visualization, sharing and affordability, Polaroid went out on a venture to find new product categories that would embody the essence of the brand. ..."Every LCD flat-screen television has a polarizer on it. It’s a core component of the technology that allows you to view the picture on a flat-screen TV," says Hardy. Fulfilling the visualization component of the Polaroid brand as well as the concept of sharing and affordability (by making the televisions at a price point that would appeal to the masses), flat-screen televisions hit on all of the brand attributes Polaroid identified, making this product category a natural fit." via Fast Company

How do 3D displays work? Passive, active, glasses and glasses-free 3D "Active 3D works on plasma and LCD TVs and requires a set of powered glasses to make the 3D image. ...These active glasses work by having lenses that have a liquid crystal layer applied to them. When voltage is applied to the lens, it turns almost completely opaque; without, they are almost completely clear. There is some light loss when you're looking through the lens even without a current applied, and it's this that can make the TV image seem a bit darker when you're watching with them on. ...To produce a 3D picture, the TV displays the image for the left eye, then the image for the right eye. While it does this, the glasses shut out the light to the opposite eye. This happens 24, 25 or 30 times per second for each eye, so it is nearly impossible for you to tell it's happening, although some people do complain of flickering, and this might be why there are reports headaches with active 3D for a minority of users." via Expert Reviews

How MIT Is Building an Affordable Hologram-at-Home System "Over the past three years, researchers in the Camera Culture group at the MIT Media Lab have steadily refined a design for a glasses-free, multiperspective, 3-D video screen, which they hope could provide a cheaper, more practical alternative to holographic video in the short term. Now they’ve designed a projector that exploits the same technology, which they’ll unveil at this year’s Siggraph, the major conference in computer graphics. The projector can also improve the resolution and contrast of conventional video, which could make it an attractive transitional technology as content producers gradually learn to harness the potential of multiperspective 3-D.

How to create your own privacy display "The necessary materials are an old LCD monitor, superglue, paint thinner (or another solvent), paper towels, a screwdriver or drill, a pair of old glasses, and an x-acto knife or box cutter. If you follow the steps below, posted on Instructables by Dimovi, an electrical engineer based out of Austin, you can easily create your own privacy monitor. You’ll be free to have covert TV-watching and web surfing experiences in no time." via psfk

Sony sidelines OLED TVs for 4K sets "South Korean rivals LG Electronics and Samsung Electronics have moved ahead of the Japanese company in this field. Sony does not see real demand for OLED TVs taking off anytime soon, whereas its 4K LCD TVs are generating revenue now and could help its TV business return to the black for the first time in 11 years in the year to March 2015. 4K TVs are priced around 100,000 yen ($970) higher than regular flat-panel TVs." via Nikkei Asian Review

Will bigger displays bump Apple past Samsung? "In fact, smartphones with a five inch and larger screen increased 369 percent, a growth rate that is much higher than the market in general. Devices in this category made up 34 percent of shipments, including a high of 43 percent in Asia Pacific. ...This appears to be bad news for Apple Inc., right? Yes and no. For now, since its screens are on the small size, this is definitely holding the company back. Moving forward, when Cupertino decides to “go big,” it will be in position to make up a lot of ground in a relatively short period of time. In other words, you can guarantee that Samsung is not looking forward to the day that Apple rolls out a larger screen." via The Bibey Post

Are mobile resolutions really that important these days? "The QHD display from LG isn’t something to sneeze at, but I do think it’s a waste for mobile technology. Even on a 5.5-inch screen, a 2560x1440 resolution seems like it’s total overkill. On a bigger screen, like for a computer or especially a TV, then yeah, that kind of resolution would be really nice; but a smartphone? Even on my HTC One, which has a 1080p display, is damn near impossible to tell where one pixel ends and where another begins. The clarity of phones is fine. What we need now is better battery life, stronger phones, and really just about anything else on a phone. But the naked human eye, even with perfect vision, will only ever be able to see so far. I’m pretty sure we have already reached that point when it comes to mobile displays. I’m pretty sure we’ve already passed it, even before this point." via PhoneDog

How digital signage is revolutionizing automotive showrooms "The dealership's [Audi City in Mayfair, central London] star attractions are the four so-called powerwalls -- nearly floor-to-ceiling screens that display a customer's chosen car. The powerwalls, created from 36 backlit LED display screens almost seamlessly joined together, are linked to high-definition touch screens mounted on tables where cars can be configured. Consumers choose the model, color, engine and other specifications on the table, then swipe the screen to send the completed car to the wall. There they can spin it around, peer inside, open the doors and trunk and even watch it drive off, complete with authentic engine noises. As with the latest iPad interaction, commands are instantly and smoothly relayed. The effect is mesmerizing. ...According to Audi, digital technology has had a powerful effect. Sales at Audi City London are up 60 percent from the traditional Audi showroom that previously occupied the site, Hanschur says, without giving exact figures." via Automotive News

What is OLED? The next wave in display technology "When color television debuted in the 1960s, picture tubes made color by electronically combined light from red, green and blue pixels. Today's dominant big-screen TVs use liquid crystals to switch a source of light on or off behind pixels. In OLED displays, "blue is the weak link, from a life and energy-efficiency perspective," said Mahon. "It's a high priority to develop deep, long-lived blue OLEDs to complete our suite of colors." Red and green OLEDs are rated to last more than 20 years, but blue lasts only about four years. Blue OLEDs used in smartphones and other devices are fluorescent OLEDs, a different type that aren't as efficient, Mahon said, and are made by a half-dozen companies, such as Dupont and Idemitsu Kosan of Japan." via CED Magazine

How can avionic displays be safer? Engineers find way to lower risk of mid-air collisions for small aircraft "At issue are cockpit displays of traffic information (CDTIs). These are GPS displays used by private pilots to track other aircraft in their vicinity. However, pilots often focus on the closest aircraft on the display—a habit that can pose a significant hazard. ...Researchers modified the CDTI so that the plane that would cross a pilot’s path first either began blinking or was colored yellow. The researchers tested the modified CDTI in a flight simulator with a panel of licensed recreational pilots. The research team compared the pilots’ response times and decision-making accuracy when using the modified and unmodified displays." via R&D Magazine

How will new military displays help soldiers on the battlefield? "The Q-Warrior, the latest version of BAE Systems’ helmet-mounted display technology, looks like a fighter pilot’s head-up display but has been specially designed for the soldier who needs unique capabilities, such as identifying hostile and non-hostile forces, as well as coordinating small unit actions. Paul Wright, Soldier Systems’ business development lead, and Mark Wilkins, project technical lead for Q-Warrior, explain: “Q-Warrior increases the user’s situational awareness by providing the potential to display ‘eyes-out’ information to the user, including textual information, warnings and threats."" via IHS

How will the Apple touchscreen develop? New Patent Shows Hints "Just over a year ago, the first detail of a patent describing a potential wraparound display for an Apple device cropped up. In the diagrams, the device had a screen that went clear around the sides and looped over the back as well, covering most of the phone except for the top and bottom. Though that patent came out well before the iPhone 5S, it may have been too soon for Apple to put the design into practice, as flexible screens and tech has a ways to go yet — as can be seen by Samsung (SSNLF.PK) and LG’s “flexible” smartphones that bend just a few degrees. The design, though novel, also seemed a bit impractical, as very few people can reasonably need a phone with a screen they can only see half of at any given time. This latest patent blends a bit of the novelty of the earlier design with more practicality. Rather than suggesting a screen that wraps all the way around the device, it stops short, only going partway around one side or both [sidewall]." via Wall St. Cheat Sheet

How is digital signage taking creativity to new levels? Interactive street display brings TV show to life "Live Vinyl is a display technology developed by Future Colossal, and it is employed in this case to create a living, breathing version of an intersection in Victorian London with carriages darting by, fog rolling in and birds flying about. The technology was inspired by the artwork of Jim Campbell, who is known for working with LED light installations, and incorporates techniques used in projection mapping. “We align the images of an ultra high-resolution print with an image rear-illuminated by low-resolution LED walls,” Lee-High explains. “The LED walls bring life to the printed image by changing dynamic lighting, creating effects and showing AI [artificially intelligent] characters.” “When viewing the display, one looks both at and through the image,” according to Lee-High. “It is an effect the people have not seen before, and it is fun to watch them try and figure out the magic that is making it visible."

Intel creates floating display "Intel Corporation has come out with a 3D interface that allows users to make interact with devices by touching illusions created in the air. The technology creates an interactive 3D illusion with the help of a 3D camera and a special type of glass, says a report from BBC. ...In the near future, such technology could be located in public places like cash dispensers or photo booths; providing a more secure and hygienic experience, according to its developers." via ValueWalk

Innolux becomes world leader in displays for automotive market "Innolux at the end of last year managed to best its closest competitors, Japanese firm Japan Display Inc. and Sharp Co., and maintained its advantage over South Korea's LG Display, ranked fourth in the world in the sector. In fifth place in automobile screen sales at the end of last year was Taiwan's AU Optronics Corp., with 11 percent of the world market share, which - combined with Innolux's 23 percent - gives Taiwan more than 34 percent of global sales. ...The rapid expansion of the market for automobile accessories in China, in particular, has contributed to Innolux's increase in automobile screens." via MENAFN

Display bridge solution powers pico projector in mobile device ""One challenge of embedding pico projectors into smartphones is the lack of processor support for both a display and a pico projector," said Paul Karazuba, Quicklogic's senior product marketing and media manager. The QuickLogic ArcticLink III BX6 allows the single display interface signal from the device's applications processor to be duplicated and bridged so that it can drive both embedded display and the integrated pico projector." via NewElectronics

How can marine displays be improved? "Innovations in computer display technology would seem to have recently hit a plateau. With the advent of LCD panels, improvements in computer displays have recently been limited to larger screens, higher pixel resolution, greater energy efficiency, and lighter, more efficient use of base resources. Yet there remains two areas where computer display manufacturers can continue to offer improvements: the human-machine interface, and local display intelligence. To offer the most effective solutions, improvements should maximize their utility with improvements in performance for specific environmental conditions. There are several features a computing display can bring to embedded computing stations aboard ships, or ocean platforms; in particular, the two most glaring problems for users when out at sea are low-light environments, and the technical ignorance of the average user when faced with crashes or machine malfunctions. Advances in the display interface can lessen the effects of these problems and much improve the user experience. " via MarineLink

Pepsi Rivals Coke's Freestyle With Touchscreen 'Spire' Debut "Pepsi Spire lets users be their own mixologists to create up to 1,000 customized beverages. ...Pepsi Spire 1.1 is a countertop self-service unit that allows consumers to create up to 40 beverage combinations using a 10" touchscreen. The 2.0 model increases variety to 500 beverage combinations and features a 15" touchscreen, and is also available as a countertop crew-service unit for restaurant staff. Launching soon is Pepsi Spire 5.0, which will allow consumers to create more than 1,000 beverage combinations using a 32" touchscreen." via Vending Times

What are the limits of touchscreens and how can they be fixed? "Accurate typing isn’t the only problem with touch screens and their fleeting electronic pages. Many studies suggest that people’s memory and comprehension are often better when they read long passages on paper than on screen, said Mariette DiChristina, editor in chief of Scientific American, which in August held a conference on learning in the digital age. ...Another problem with touch screens’ transitory images is that they don’t help students create a mental map of what they’ve read and what’s to come — an overview that is known to be useful in memory. “You might remember that something you read yesterday in the paper was in the middle of the page, or in the right corner,” Dr. Wästlund said. “Even though you haven’t tried to memorize position, you have built this internal model” — like the page layout of a newspaper. That kind of cognitive map or physical landscape into which readers fit new knowledge is much harder to build with fleeting e-pages." via The New York Times

Is coding games for touchscreens difficult? "Often games designed around touch will have gestures. Slice through this, slide across this path, drag through the middle of that. Games designed around a mouse will have clicks and drags, where the endpoints are the critical factor. In most respects, it is just like dealing with a pattern of points. A mouse is more about the position at the moment of click, or the moment of release: "down" and "up" positions are important, but the middle is not. With touch devices, the location of "down" and "up" are less important, usually more important are the points in between. Since it often involves slightly more processing, matching the gesture and deciding if a gesture was close enough to a range rather than just testing the coordinates at a down/up/click event, it is consequently slightly more complex." via GameDev.net

Automotive Q&A about head-up displays "Q: How do you see the US market for HUDs shaping up in terms of OEM adoption? And do you see the HUD becoming more important as a route to prevent distracting the driver too much? A: Both the US and global HUD market are in the midst of tremendous growth. Over the past several years, there haven over 20 new adoptions of HUD, as well as several car manufacturers launching their first model equipped with HUD and all market indicators suggest that growth trend will continue going forward. HUD systems enhance the overall driving experience by allowing drivers to keep their eyes on the road while still viewing critical vehicle data, minimising driver distraction. With the increased adoption of active safety features such as blind spot detection and lane departure warnings along with navigation and smart phone integration, car manufacturers seek to find a way to deliver all of this information to the driver without "overloading" them with information and causing a distraction. HUD systems are emerging as an optimal method to help combat driver distraction." via just-auto

New research examines avionic display design and regulation "Synthetic vision, and its ability to enhance situational awareness will also be a focus for NASA, according to Ellis. "One of the primary things that we're focused on particularly (is) looking at the safety enhancements. One of them is looking at synthetic vision displays and developing minimum requirements specifically in regard to how they better improve situational awareness and their potential for preventing spatial disorientation and Loss of Energy State Awareness [LESA], so that would be something that provided directly to OEMs in terms of how they make their avionics and what's required by the FAA when they're doing so," said Stephens." via Aviation Today

Ingram Micro: 'It's time to take digital signage technology seriously' "Q: Is this an untapped opportunity for resellers? What are the benefits of embracing pro AV/digital signage sales? A: Without a doubt. If you look at the traditional IT resale market, we’re seeing constantly that the print and PC markets are in decline, and now everybody is moving into managed print services (MPS). The AV market is the total opposite. If you look at the professional audio/visual market and you look at the data Futuresource and others provide, it’s all growing. Retail digital signage is growing and corporate digital signage is growing. Our message to our partners is it’s time to take that technology seriously, because it is going to be the future of how everybody communicates, regardless of the size of their business. " via PCR

Has LCD Innovation Reached the End of the Line? "LCD owns the future by default. Still, cultural evolution gives rise to a desire for new means of interpersonal communication and information consumption. And some new products will require display characteristics that have not existed in the past, at least not at reasonable cost. An example: my new Samsung Galaxy S5 has a display that is truly sunlight readable. That is a characteristic most users would want in a cell phone, but it has taken years for the industry to supply it at a consumer-friendly cost. The GS5′s display is, of course, an AMOLED. Can LCD do what the GS5′s AMOLED is already doing?" via Display Central

What are the design considerations for large-area touchscreens? "As screen sizes increase, the main challenge for capacitive touch is maintaining the same performance users have come to expect from a mobile phone but over a larger screen. This means scanning more intersections, over more surface area, in the same amount of time. ...It is challenging for large screens to maintain fast refresh rates because the touch controller needs to sweep greater surface area, gather data from all intersections, and process that data." via Electronics Weekly

Why Are Mobile Display Revenues Overtaking TV Displays? "With larger display area and comparatively higher unit prices, LCD TV panels have generated a majority of FPD revenues since 2006, but over the past three years, the market for mobile devices has expanded. The recent trend toward higher resolutions, slimmer and more lightweight specifications, wider viewing angle, lower power consumption, and the emergence of LTPS and OLED displays are causing mobile display revenues to soar." via PCB007

Why Did Apple Just Buy A Tiny Display Company And What Could It Mean? "Apple used to push display technology with its products, most notably when it brought the Retina Display to the iPhone. But that hasn’t been the case lately, which makes its recent acquisition of tiny LuxVue Technology all the more interesting. But LuxVue’s technology has fascinating implications around low power and high brightness and could eventually mean Apple will manufacture its own displays for the first time. It could also allow the company to gain technological leadership again, as it has with its own in-house chipmaking, which was also made possible by an acquisition that didn’t seem especially all that important at the time. In a scoop over at TechCrunch, Apple responded with its typical non-comment about what it intends to do with LuxVue and to say the company is little known would be a case in understatement." via Forbes

How Can Quantum Dots (QDs) Increase Display Color and Brightness with Less Power? "The optical and electrical properties of the manufactured crystals can vary markedly according to their size and shape: The bigger the dot, the larger its bandgap and the longer the wavelength it emits. The smaller the dot, the smaller its bandgap – which means a shorter wavelength due to the quantum confinement of electrons and holes in these nanomaterials. Quantum dots offer marked advantages over fixed-spectrum conventional phosphor technologies because QDs are tunable, so they can be induced to emit at a very narrow wavelength. Improvements to the technology in recent years are also making them more attractive." via Photonics

Why is smartphone component production causing LCD display shortages and hurting the display industry? "In recent months, there has been growing demand for a number of high-value components for smartphones and tablets, including fingerprint sensors, CPUs, cameras and touch controllers, along with 4K television timing controllers. According to NPD DisplaySearch large-area displays analyst Peter Su, semiconductor manufacturers in Taiwan have increasingly been prioritising the manufacturing of these higher-value components over timing controllers [T-cons] for LCD displays. In a statement, Su warns the prioritising of higher margin components is leading to a shortage of T-cons." via Smart Company

Sharp improves TN LCD panels with clever light scattering optical film "Adding a film to a TN panel isn’t a new concept, but Sharp’s film promises to do a much better job of improving angled viewing. Typically, existing films only improve viewing horizontally, not vertically. Sharp’s new optical film improves both by scattering light and being able to control which direction that light is scattered in." via Geek

How have avionic displays entered the future? "Analog gauges, often referred to as “steam gauges,” ruled the instrument panels of all aircraft for nearly 80 years. But with the advent of powerful and inexpensive semiconductors, and the clarity of liquid crystal diode displays, it became easier to combine many instruments onto space-efficient, yet easy to read, glass screens called multi-function displays (MFDs). Along with advancements of glass display screen came synthetic vision systems (SVS). Loosely defined as real-time, 3D color imagery, SVS makes paper navigation products nearly obsolete. Instead, it uses a preloaded, internal database to create a pilot’s-eye view of the terrain the aircraft is passing over at that time." via Aviation Today

What are the challenges of designing automotive heads-up displays? "HUDs work by projecting an image, usually from a liquid crystal display (LCD), onto the windshield or a piece of glass above the instrument cluster. ...Designing a good HUD presents many challenges. It needs to have a very wide contrast ratio. It must display an image bright enough to be clearly seen on a sunny day, but also dim the image so that it does not obscure the driver’s vision at night." via EDN

How did Apple and Samsung get into a smartphone war? "The first products known to have been the focus of one of Samsung’s major price-fixing conspiracies were cathode-ray tubes (C.R.T.’s), which were once the technological standard for televisions and computer monitors. According to investigators in the U.S. and Europe, the scheme was quite structured: competitors secretly got together in what they called “Glass Meetings” at hotels and resorts around the world—in South Korea, Taiwan, Singapore, Japan, and at least eight other countries. Some of the meetings involved the most senior executives, while others were for lower-level operational managers. The executives sometimes held what they called “Green Meetings,” characterized by rounds of golf, during which the co-conspirators agreed to raise prices and cut production to receive higher profits than would have been possible had they actually competed with one another. The scheme was eventually exposed, and over the course of 2011 and 2012, Samsung was fined $32 million in the U.S., $21.5 million in South Korea, and $197 million by the European Commission." via Vanity Fair

How to Install a Heads-Up Display in a Fifth Gen Camaro "There’s just something about checking your speed, gas gauge, and tachometer without having to look down that makes driving a new Camaro quite enjoyable and, once you’ve experienced that luxury, it’s quite difficult to go back. Unfortunately, not every fifth-gen Camaro shipped from the factory with a HUD and if you’re in the market for a used 2010, or you’re an original owner who didn’t have the option available at the time of purchase, you might think you are out of luck. But fear not fans of the futuristic windshield gauge concept, Heads Up can be yours and it can even be installed in your own driveway with a couple of factory parts and a weekend worth of work, if you’re willing to put in the effort. That said, we should mention up front that this can be quite a daunting task if you’re easily intimidated by making a mess in your new Camaro and it certainly isn’t a modification for the faint of heart. You’re going to have to dig in deep and, at some point, wonder if you’ve made a major mistake." via GM High-Tech Performance

Will virtual reality (VR) make flat panel displays obsolete? ""A traditional display, especially larger ones, they're very expensive to manufacture and ship... it's literally just a lot of plastic and a lot of glass in a big box that has to be shipped across the world," Oculus VR founder Palmer Luckey continued. "Sometimes it breaks, then it has to sit on a giant store shelf until someone buys it. Once VR is commoditized, let's say 10 years from now, the tech from two years prior, you'll be able to buy a really good VR headset for $99, because there's not much material, once it's all commoditized..."" via Ars Technica

UK Developers Create Reach-Through Displays For Tabletops "Researchers from the University of Bristol have reportedly developed a new reach-through tabletop display with personal screens comprised of a curtain of mist, according to research scheduled to be presented later this month at an international conference on human-computer interaction. ...The device is known as MisTable and it is described as a tabletop system that combines a traditional interactive table with personal monitors built using fog between the user and the table’s surface." via redOrbit

New display brings the Internet to your wall "That's where Electric Objects, Jack Levine's new venture, comes in. He wants to take some of the more serene parts of the Internet out of that stress-inducing device sitting on your desk, and put them on your wall through a different kind of device. ...The product is still in the prototype phase. But the current unpriced model hacked together by Levine is bigger than an iPad and, at 23 inches, smaller than most TVs. A final, more polished version will include a screen designed to be on at all times, with sensors that detect if anyone is nearby, activating the screen. It will also have a tilt sensor to reorient itself in either landscape or portrait modes, and an ambient light sensor to keep the brightness low and subtle." via Fast Company

Why Some Doctors Like Google Glass So Much "At a recent event hosted by Google’s Cambridge branch, doctors from across the country came to show off how they’d thought of harnessing Glass for medicine. One presenter, Rafael Grossman, a surgeon based in Bangor, Maine, was the first person to use Glass during live surgery. He thinks the technique could help doctors teach new surgeons. But for the pilot at Beth Israel, video is off the table, at least for now. “We wanted to stay away from anything that could potentially be misconstrued as leaking patient information, so until we had a case study and a good foundation, we purposely stayed away from enabling the video feed,” says Horng." via MIT Technology Review

How tiny company Amorphyx is seeking to reshape the huge, mature business of manufacturing displays "Cowell and Amorphyx co-founder and chief executive John Brewer Jr. are preparing for a whirlwind, four-day trip to Taipei, Japan and South Korea, where they will meet with executives of major display manufacturing companies including Samsung and Sony. They hope to make progress toward an agreement to cooperate in testing and refining a process that would replace silicon-based transistors with amorphous metals-based resistors. Amorphyx has been doing this on a small scale in the lab, where it sprays two layers of metal compounds and an insulator onto wafers, then tests them for conductivity. Now it hopes to kick the process to a higher production volume. For the layperson, what this means is that displays built with Amorphyx's non-silicon process would consist of fewer layers than prevailing liquid-crystal manufacturing technologies, cost less and could be used on flexible surfaces." via Oregon Live

Shape-Shifting Touchscreen Buttons Head to Market "That technology was developed by startup Tactus Technology, which uses tiny fluid-filled channels and elastic blisters to make buttons rise up from a device’s screen and then disappear without trace when they’re no longer needed (see "Demo: A Shape-Shifting Smartphone Touch Screen"). Electronics manufacturing giant Wistron has now modified equipment at one of its factories in China to produce touch-screen panels with the shape-shifting technology inside. Wistron is one of the world’s largest electronics manufacturers; it’s made devices for brands including BlackBerry, Apple, and Acer. The company also recently became an investor in Tactus." via MIT Technology Review

A Joystick-Inspired Interface Could Solve Smartwatch Displays' Biggest Problem "Think of the way we used to use those small nubs located in the middle of an older laptop’s keyboard to move the cursor, and you’ll understand how this concept — created by Robert Xiao, Gierad Laput and Chris Harrison — works. Except that instead of a cursor, it’s navigating a mobile device’s UI that usually relies on taps and gestures. The problem is that your fingers are usually far too large to use all the same gestures you rely on with your smartphone on a watch’s tiny touchscreen. And you usually end up blocking the display in the process, making it even more difficult. So this concept reproduces most of that functionality with a watch display that can be subtly tilted side to side, up and down, rotated, and even pressed like a button." via Gizmodo

Should touchscreens be more intuitive? "Chris Harrison from CMU's Future Interfaces Group thinks modern, "flat" software doesn't profit from our dexterity with real-world tools like cameras, markers or erasers. To prove it, he created TouchTools, which lets you manipulate tools on the screen just as you would in real life. By touching the display with a grabbing motion, for example, a realistic-looking tape measure appears, and if you grab the "tape," you can unsheathe it like the real McCoy. " via engadget

Japan’s New Floating Touchscreen "The process is very fast paced, actually...allowing for highly responsive image manipulation. Hundreds of pictures are taken per second by stereo cameras. This allows the technology to precisely track a user’s hand and finger gestures as they relate to the floating images on the screen. These gestures are then translated into commands by computer software. Professor Ishikawa explains the advantage of gesture technology: “In hospitals and such during surgery, when one’s hands are dirty, it’s still possible to use this, or to use it in a variety of situations at a construction site.”" via Trefis

Atmel Announces Next-Gen Touchscreen Controllers "Atmel is well-known in the context of MCUs and FPGAs -- but it is also a major player with regard to touchscreen technology, especially in the large format screen space. ...The mXT1066T2 and mXT1068T2 controllers support both mutual-capacitance and self-capacitance sensing. By intelligently switching back and forth between the two and using a hybrid approach, designers can achieve optimal power consumption and noise immunity, even in high humidity and moisture environments, while supporting bare finger and gloved operation. Additionally, mXT1068T2 controllers supports hover operation in which the user's finger can be up to 20mm above the touch surface." via EE Times

Touchscreen Interface Based on Little Mobile Robots "Thumbles features tiny little omnidirectional robots that live on top of a projected screen. By grabbing them and dragging them around as they try to drive around, you can experience a completely new type of physical interactivity. What makes Thumbles unique is that the robots can move by themselves. They can provide force feedback, or dynamically form different kinds of physical controls, or act as virtual representations of things like molecules or mechanical structures. (Video)" via IEEE Spectrum

Could 'Star Wars' holographic displays become a reality? "HP Labs spinout Leia believes it is. Using a clever system of diffraction gratings, its small displays produce 64 different versions of each image, allowing a viewer to move around an object or person shown on the display as if it was right in the room with them. CEO David Fattal spoke to an eager crowd of imaging researchers at Stanford University about his company’s progress since it separated from HP. While the concepts behind Leia are the same as when the team’s work at HP was first published in Nature last year, the new company now has full color prototypes with improved resolution as it prepares for a product launch. Key to Leia’s technology is the use of fairly simple diffraction gratings at each pixel to redirect the backlight in different directions. " via ExtremeTech

Will digital signage replace plane windows? "Spike Aerospace, a Boston engineering firm that’s developing a small supersonic jet, recently caused a stir when it announced its plane wouldn’t have any windows in the passenger cabin. Instead, thin screens installed on the walls of the aircraft would display live views captured by cameras mounted outside. ...The cockpit, of course, will still have a real-life view, but Kachoria predicted windowless cabins would be the norm within 20 years on small planes like the one his company is working on." via NBC News

How will flexible electronics revolutionize user interface displays and everything else? "With RFID, you have to embed electronics into your travel card or keyfob or whatever – with Touchcode, from T+Ink, you just use conductive ink, which is cheaper, thinner and more flexible, to transmit information to the reader. The best thing about this system is that the reader can be found in any modern mobile device: the screen. Capacitive touchscreens usually work because of the conductivity in your finger; here, they just read the conductive pattern of the ink on the smart card, smart packaging or what have you. In this example, holding the promotional “Cars 2″ card over the suitable app brings up an image of the relevant car. It’s a darn sight easier to use – and more pleasing to the eye – than a QR code that needs to be held in front of the phone’s camera." via Gigaom

Are OLED displays dimmer than LCD? "According to DisplayMate, Samsung’s Super AMOLED Galaxy S5 is the brightest display they’ve ever tested, defeating the traditional notion that OLED screens are dimmer than their LCD counterparts. ...Samsung kept using the diamond-shaped subpixel that leads to higher efficiency without the graininess that came from PenTile arrays. The larger blue and red subpixels are diamond-shaped, while the green subpixels are oval, making it easier to squeeze in between the others while maintaining the highest quality possible…" via IntoMobile

Calgary-developed tactile touchscreens: Stevie Wonder tested, CNIB approved "Doug Hagedorn is the founder and CEO of Tactalis (formerly known as Invici), a Calgary startup he launched in 2012 and now includes a half-dozen people on the team. Their technology uses an array of magnets embedded beneath an LCD screen that can be activated and deactivated, corresponding with images on the display. Using a metal stylus or a ring on the tip of the finger, users can then “feel” the images in a dynamic way." via Metro News

Is Facebook's purchase of heads-up display company Oculus a good or bad thing? "No one seems to have seen the acquisition coming, least of all Oculus itself, which apparently thrashed it out in a matter of days after Zuckerberg decided to take it on. ...But the Rift needed this kind of cash injection to get to the point where its technology would be commercially viable. ...One of the biggest problems is latency between the movement of the headset, and the updated image. 50ms is the maximum, beyond which motion sickness can set in – and advocates suggest that sub-20ms is optimal. Another problem is motion tracking. Unless motion is tracked perfectly, the user's experience of where they are can differ slightly from the image displayed, leading to nausea." via E&T Magazine

Why is Samsung’s breakthrough in graphene research so promising for display technology? "Samsung calls the new method “wafer-scale growth of single-crystal monolayer graphene on reusable hydrogen-terminated germanium.” Traditionally, graphene has proven difficult, and therefore expensive, to produce. This has been due almost exclusively to the fact that producing graphene, especially in larger contiguous sheets, required a destructive process to transfer the material from its production environment over to the components it is being used to help build. ...Previous methods required a liquid based transfer of the graphene, but now, the germanium substrate layer that graphene is produced on top of can be re-used for continual growth of graphene, instead of being destroyed in the transfer process." via Android Authority

Why is Apple in talks to buy Japan display chip-maker Renesas "Renesas SP Driver, the largest maker of chips used to control mobile device screens, supplies all three of the companies that make displays for the iPhone, industry sources say: Sharp, Japan Display Inc and South Korea's LG Display Co Ltd. "There's no doubt that, for Apple, the question of who buys Renesas SP is a matter of grave significance," said one Japanese display industry source, who asked not to be identified due to the sensitivity of the matter. Control over the supply chain has become increasingly crucial among smartphone makers. While up to now Apple has relied on outside suppliers for many key parts, Samsung makes vital parts for its Galaxy smartphones, from screens to chips to capacitors, in-house. That gives it greater control over costs, production schedules and specifications, as well as product information." via Reuters

How to stretch a display and maintain pixel resolution "We dream of a single device with a size-variable screen display that can function as a phone, a pad, and a tablet as required. We want a small screen device for voice communications but a large screen when reading text or watching movies on the same device. Several engineering prototypes of so-called rollable or foldable, sometimes multi-axis foldable, screen displays have been demonstrated. The size of the viewing area—thus the device planar area as well—is small when the displays are stored in a rolled or folded form, but can be enlarged when unrolled or unfolded. However, such devices are generally bulky due to the form factor of the rolled or folded screen displays. We considered how to change the size of the screen display and its form factor." via SPIE

Disney Research Pixelbots Tell the Story of the Universe "Three years ago at ICRA in Shanghai, Disney Research presented a prototype for an artistic robot swarm. The swarm was made up of lots of little wheeled robots with LEDs, each of which acted as an individual mobile pixel in a dynamic image made entirely of robots. Disney and ETH Zurich have been refining this idea, developing both software and hardware and adding more robots to the mix. At the ACM/IEEE International Conference on Human-Robot Interaction earlier this month, the latest version of this Display Swarm, now called Pixelbots, reenacted the story of the Universe (video)." via IEEE Spectrum

How Can Stereoscopic Displays Address the Accommodation-Convergence Problem? "The technology discussed by Dr. Bos was a means to use active liquid crystal based eyeglass lenses to address the well-known accommodation-convergence problem found in many stereoscopic display systems. The proposed means to fix the focus problem is, in principle, quite simple: use a camera to determine the “toe-in” of the user’s pupils. Based on this information, determine the distance from the viewer to the virtual object. Add to this the measured distance between the viewer and the display screen and it is possible to determine the power of a lens that can focus the user’s eyes at the proper object distance." via Display Central

New Apple tech could revolutionize touchscreens "FTIR [frustrated total internal reflection] uses infrared lights to bounce light off the back of a touchscreen. If there is no interference, or frustration, then the infrared light will completely reflect off the surface of the touchscreen, similar to how the surface of a pool can act as a mirror when viewed at high enough angles. If there is interference from a finger on the touchscreen, then sensors will pick it up in order to determine where the touch input hit the display." via BGR

Atmel, Corning Work On Super Thin Capacitive Touchscreens "This particular collaboration would merge Atmel XSense flexible touch sensors with 0.4mm damage-resistant Corning Gorilla Glass, where the two of them work hand-in-hand to deliver outstanding capacitive touch performance despite having a thinner flat or curved cover glass. It is because of the unique circuit design of XSense that paves the way for design engineers to draw up ever narrower device borders, so that the user would be able to enjoy a more optimal viewing area. " via Ubergizmo

How touchscreens could recognize user 'signatures' "Cybersecurity researchers from the Georgia Institute of Technology have gone a step further. They’ve developed a new security system that continuously monitors how a user taps and swipes a mobile device. If the movements don’t match the owner’s tendencies, the system recognizes the differences and can be programmed to lock the device. The new system is called LatentGesture and was used during a Georgia Tech lab study using Android devices. The system was nearly 98 percent accurate on a smartphone and 97 percent correct on tablets." via Laboratory Equipment

How can open source touchscreens be useful to engineers? "I bought an Arduino Mega and started putting together the custom electronics in the form of a daughter board (Arduino calls them "shields"). However, it needed to be a standalone unit, so what could I do for user interfacing to the Mega that was flexible? Touch screens. Adafruit, a hobbyist site like Sparkfun, offered a 2.8" TFT Touch Shield for Arduino for $59—a second-generation version is now available for $39.95. The libraries are quite easy to use and it gave me the flexibility I needed to make an early prototype of the full system and then refine the safeties once we had some actual test experience with the final hardware." via EDN

What Are Augmented Reality Displays: Their Past and Potential "Computer graphics pioneer Ivan Sutherland established the basic concepts of AR as known today in his seminal 1968 paper “A Head-Mounted Three Dimensional Display”. Sutherland wrote, “The fundamental idea is to present the user with a perspective image which changes as he moves. The displayed material can be made either to hang disembodied in space or to coincide with maps, desktops, walls, or the keys of a typewriter.” Sutherland’s visionary impact is clear when you realize that his work occurred at a time when computer graphics was in its infancy and displays could only render very low-resolution lines. ...On Thursday, May 29, 2014, in Santa Clara, California, the Embedded Vision Alliance will hold its fourth Embedded Vision Summit. Embedded Vision Summits are technical educational forums for engineers interested in incorporating visual intelligence into electronic systems and software." via Electronic Engineering Journal

What is haptic capability for tablets? "The news comes from the recent Mobile World Congress 2014 in Barcelona where Fujitsu Laboratories Ltd. (Kanagawa, Japan) demonstrated a prototype tablet with haptic capabilities. ...The introduction of an ultrasonic vibration on the tablet surface creates a high pressure layer of air between the tablet’s surface and the user’s fingertip. This has the effect of reducing friction and creating a floating effect. Utilization of this phenomenon makes it possible to create a slippery sensation on the tablet surface. Up till now, this particular sensation has been difficult to achieve using other techniques." via Display Central

How does a touchscreen display provide blood testing? "But soon, thanks to startup Qloudlab, based in the microengineering lab in Switzerland's EPFL tech university, these patients may be able to use the touch screens on their phones or other devices to test their blood coagulation, all in the comfort of their own homes -- or wherever. ...Using the sensors that can determine where it is being touched (i.e. where the screen's electric field is being disrupted), the screen can detect with incredible precision when and where the blood is moving through those tiny channels across the small surface area where the sticker touches the screen." via CNET

How will digital signage change the dining experience: Pizza Hut introduces digital signage touchscreen menu table "As shown off in its promotional video, the Pizza Hut touch-screen-enabled table concept would allow anyone with an iPhone to sit down and have their identity recognized. That would potentially mean that payment methods, favorite items from the menu and other details could be instantly relayed to the restaurant, as well as any allergies that would mean certain foods wouldn’t be suitable. ...Without a doubt this concept bears a resemblance to Microsoft’s own Surface table, something which never really took off properly, until Microsoft shrunk it down a few feet and turned it into a tablet. (video)" via Redmond Pie

What is digital signage and how can you implement it? "Digital signage is the use of screens in stores to deliver marketing messages and improved shopping experiences to customers. ...Most businesses have small or limited budgets, so it’s advisable to test out options before you invest. A phased approach is a good way to begin experimenting with digital signage. Digital signage and augmented reality can be defined in simple terms as the enhancement of reality. This is often through the digital presentation of information and it can be used on kiosks. It effectively defines the link between 3D and real images and it uses advanced digital imaging techniques." via Internet Marketing Advice

What is Kinoma Create? "Kinoma Create is the JavaScript-powered construction kit for makers, professional product designers, and web developers with no prior hardware experience. With Kinoma Create, you can create personal projects, consumer electronics, and Internet of Things prototypes more quickly and easily than ever before. ...Inside Kinoma Create is a power efficient ARM CPU, Wi‑Fi and Bluetooth connectivity, a capacitive color touch screen, and tons of I/O for sensors — all nicely integrated, all ready to go right out of the box." via indiegogo

Why doesn't Apple does make a touchscreen MacBook? "The appointment of Craig Federighi as the leader of all of Apple’s software efforts could have been seen as a sign of that merger, but Federighi himself is adamant that the Mac will always be true to itself. “The reason OS X has a different interface than iOS isn’t because one came after the other or because this one’s old and this one’s new,” Federighi said. Instead, it’s because using a mouse and keyboard just isn’t the same as tapping with your finger. “This device,” Federighi said, pointing at a MacBook Air screen, “has been honed over 30 years to be optimal” for keyboards and mice. Schiller and Federighi both made clear that Apple believes that competitors who try to attach a touchscreen to a PC or a clamshell keyboard onto a tablet are barking up the wrong tree. “It’s obvious and easy enough to slap a touchscreen on a piece of hardware, but is that a good experience?” Federighi said. “We believe, no.”" via Macworld

Will Your Next TV Be An LCD? Not If This Startup Has Its Way "Kateeva, which has 68 employees on board after acquiring OLED Plus in Korea today, has some intriguing technology that could change the game — and level the playing field at the same time. ...To date, all the OLEDs you’ve seen — whether on your Samsung phone, or one of the high-priced TVs — have been made using an expensive, wasteful, sloppy process. The OLED material is vaporized and then winds up on the screen once it re-forms into a solid. Merck, which supplies the chemicals that form the OLED material, believes this method has a dim future: “OLED production based on chemical vapor deposition can hardly be cost competitive to LCD,” it said in a recent presentation on the topic." via Forbes

Why Are Automotive LCD Instrument Panels On the Rise? "With drivers becoming increasingly inundated by technology in the dashboard, the focus for automotive designers and engineers has primarily been on the "center stack" of the interior, where primary screens and controls typically reside. But as LCDs are added to—and even take over—the instrument panel (IP) and displace analog gauges, some of the coolest innovations are happening right under drivers' noses — and appearing in lower-priced cars. ...The reason for this IP innovation is that drivers are being asked to process more information while behind the wheel, and automakers and their suppliers are tasked with presenting it in a way that doesn't divert attention away from the road." via PC Mag

Will New OTFTs Revolutionize Flexible Display Technology? "Adding to the growing list of companies or research firms that are exploring the technology, the UK-based Centre for Process Innovation (CPI) recently showed off its new backplane fabrication process that will allow organic thin film transistors (OTFT) arrays to be bent up to a radius of 1mm without showing any significant reduction in performance. As the technology advances, the OTFT arrays could potentially be integrated into foldable, ultra-flexible AMOLED backplanes. This in turn could open the door to all sorts of new types of flexible and foldable devices." via Android Authority

Display database for engineers Search thousands of display panels by multiple characteristics and compare results side-by-side using the display database multisearch.

Are AMOLED displays at risk of burn-in? "The problem is the “O” in the AMOLED acronym, which stands for “organic”. The organic compounds used in AMOLED displays are polymers or copolymers, such as polyfluorene (PFO) and polyphenylene vinylene (PPV), both of which degrade with use. This is partly due to the fact that the chemistry involved in creating the electroluminescence is irreversible, so the luminous pixels degrade as they’re used up, like a battery. These organic materials tend to crystallise, too – an effect that is exacerbated at higher temperatures. That’s something to bear in mind the next time your phone becomes warm while you’re playing a game or watching a video." via PC Pro

Will Chinese display panel manaufacturers pose a threat to Taiwan manufacturers? "Taiwanese flat-panel makers could see their position in China threatened by local rivals by 2016, when Chinese firms are expected to begin mass producing next-generation products, a local market researcher predicted on Wednesday. Mass production of panels started at two advanced Chinese plants in the third quarter of 2011, and four others are expected to catch up by 2016, moving China forward in the panel industry, according to Delux Chen, a flat-panel industry analyst at the Photonics Industry and Technology Development Association (PIDA)." via Want China Times

Taiwan's TAITRA looking for next big thing in display panel sector "Most notably, TAITRA Chairman Wang Chih-kang [in January] urged Taiwan's display panel makers to ramp up efforts toward innovating new products and developing new technologies amid heightened competition from mainland China. China last year imported about US$4.5 billion worth of display panels from Taiwan, said Wang. With production capacity growing rapidly across the strait, and increased efforts from South Korean competitors in the China market, the industry may not be able to expect procurement to continue at volumes seen in previous years, Wang said. “While Taiwan still retains a lead in display technologies, innovation remains the only path for the sector's survival,” said Wang, while also urging structural reform across industries and further deregulation of Taiwan's market." via The China Post

F-35 Test Pilots Will Begin Flying “Gen” Helmet Display "Getting the HMDS right is a serious issue because the F-35, the DOD’s costliest weapons program, was designed without a pilot’s heads-up display, a feature that is common to fourth-generation fighters. In September 2011, F-35 prime contractor Lockheed Martin (Stand CS02) awarded a contract to BAE Systems (Stand U67) to develop an alternate HMDS with detachable night-vision goggles (NVGs) as a fallback system in the event VSI failed to resolve issues with the chosen helmet-mounted display." via AIN Online

Can New HMI alternatives improve operations and cut costs? "The fewer moving parts of multitouch tablets make them a better choice for workers who visit dusty, wet, and corrosive environments. Industrial tablets have the durability required for these areas, and many can be operated while wearing gloves. Furthermore, they can improve worker safety through the creation of commands that cannot be performed unless both hands are on the screen. Although it is unlikely that businesses are going to swap their functioning screens for new multitouch ones, it is highly probable they will replace worn-out screens with multitouch capability as the price for these devices drops. Multitouch functionality is also expected to become more ubiquitous due to the integrated support for the technology in new Windows operating systems. Eventually, all screens will likely have multitouch capability, so it is smart to select an HMI package that supports it." via InTech

Will OLET Slowly Encroach OLED Market? "The South Korean display industry has come out on top in LCD and OLED, becoming the envy of the world. Yet, Professor Lee Sin-doo is already making preparations for the future, refusing to sit on his laurels. What he is currently keen on is an organic light-emitting transistor (OLET). In contract to OLED that has two electrodes (the cathode and anode), OLET, a new light-emission concept, comes with three electrodes, giving it a competitive edge over OLED. OLET uses network electrodes, so it can emit light in the same structure without being affected by the type of substrates. The centerpiece of OLET lies with addressing OLED’s shortcomings. The supply of light though vertical-type organic transistors can solve OLED’s problems, so OLET will soon take over from OLED." via Korea IT Times

Will Wearable Tech Change the Smartphone as You Know It? "CA Technologies CTO John Michelsen thinks that if wearable technology does replace the smartphone, next-generation display technology will need to play a key role. "It depends on the visual technology. It's the display," Michelsen says. "What am I going to do when someone emails me an Excel file and I need to do a quick review and respond? The smartphone is barely viable as it is. If we can get display tech that lets me hit a button for a display, I think the cell phone goes away."" via CIO

How the Avegant Glyph's virtual retinal display mesmerizes "Unlike most headset displays that are built around a small digital screen, the Glyph creates an image by reflecting a low-powered color LED onto an array of two million tiny mirrors. The micromirrors shape the light into a two-dimensional image, which is then beamed straight onto the wearer's retina – hence why they're referring to it as a "virtual retinal display." Since you aren't looking directly at the light source, the image comes off as more true-to-life and, according to the designers, reduces eye fatigue." via Gizmag

How display technology based on EYEBALLS makes devices more readable "Phones typically have a light sensor which ramps the backlight up and down based on the ambient light conditions. This is a limited solution, however, as daylight can be fifty times brighter than indoor lighting. The human eye copes with this well; transmissive technologies like LCD and OLED can't. Apical's technology counters this by modifying the image, pixel by pixel, based on the ambient light, the direction of the light and the estimated viewing angle. By increasing the contrast with this "assertive" display they can keep the image on your device readable as you move from indoors to outdoors." via The Register

Japan Display announces mass production of Memory-In-Pixel reflective-type LCD module "Since the MIP structure can keep screen images in the static random access memory transistor fabricated in each sub-pixel, in the case of still images, once data is written it is kept, and ultra-low power consumption is achieved. The new scattering layer optimizes the panel’s optical design, and enables a near paper-like display. Since the display consumes very little electricity it is suitable for ultra-low power applications, like wearable devices, which are not recharged for long periods of time. " via Fareastgizmos

How a new transparent display system could provide heads-up data "Many current “heads-up” display systems use a mirror or beam-splitter to project an image directly into the user’s eyes, making it appear that the display is hovering in space somewhere in front of him. But such systems are extremely limited in their angle of view: The eyes must be in exactly the right position in order to see the image at all. ...The secret to the new system [from MIT researchers]: Nanoparticles are embedded in the transparent material. These tiny particles can be tuned to scatter only certain wavelengths, or colors, or light, while letting all the rest pass right through. That means the glass remains transparent enough to see colors and shapes clearly through it, while a single-color display is clearly visible on the glass." via MIT

How to make your gloves touchscreen capable "Our favorite method, however, is also the easiest, as it involves using a product made specifically for this job, Any Glove. A liquid material that you squeeze out onto your glove and let dry, Any Glove works on most materials, including fleece, knits, and synthetic suede. A separate solution is available for leather. And it doesn’t wash off when you wash your gloves. Any Glove has also earned approval for use on combat gloves by the U.S. Armed Services, so, you know, it’s got that going for it." via TechHive

How an HMI Can Make a Good Machine Better "The company wanted to upgrade its product line of smart roasters with a new human machine interface (HMI) that would take operator productivity, connectivity and efficiency to the next level of operational excellence. “The touch panel interface is the key point of contact for the roaster operator,” said Ludwig, and improving the interaction and control of roasters by adding advanced functionality and remote monitoring capabilities would help customers meet key performance indicator (KPI) metrics and goals." via AutomationWorld

How this 3D holographic display makes Star Wars a reality "The technology behind the Voxiebox is much simpler than it would seem. The device contains a projector that beams an image up onto a screen, which in turn vibrates up and down at a rapid speed. The rapid vibration allows the image to appear as though it’s a 3D asset. If that’s tough to picture, think of it as similar to those light trail pictures that frequently pop up on social networks. You can circle around the Voxiebox and the image quality never wavers or fades out of view. The only way the image will disappear is if you look at the display’s base head-on; you’re supposed to look at it from an overhead angle similar to the camera orientation in games like Diablo." via ExtremeTech

What are the technical merits of the pixel density race? "If there is any single number that people point to for resolution, it is the 1 arcminute value that Apple uses to indicate a “Retina Display”. This number corresponds to around 300 PPI for a display that is at 10-12 inches from the eye. In other words, this is about 60 pixels per degree (PPD). Pixels per degree is a way accounting for both distance from the display and the resolution of the display, which means that all the information here is not limited to smartphone displays, and applies universally to any type of display. While this is a generally reasonable value to work with, the complexity of the human eye and the brain in regards to image perception makes such a number rather nebulous." via AnandTech

Can Malware Log Touchscreen Swipes To Record Your PIN? "Recording touch screen coordinates “has a certain value in itself,” Hindocha says. “If you’re monitoring all touch events and the phone hasn’t been touched for at least one hour, then you get a minimum of four touch events, you can assume that is a PIN code being entered.” “The more interesting thing is, if you get a screenshot and then overlay the touch events, you’re looking at a screenshot of what the user is seeing, combined with dots, sequentially, where the user is touching the screen.”" via Forbes

How Did Touchscreens Get Invented? "Oddly enough, the underlying technology for touchscreens wasn’t even thought up until the 1940s. Sadly, this concept was then left... well, untouched... until 1965, when one E.A. Johnson of the United Kingdom had another stab at it. Johnson came up with a finger-driven touchscreen that historians generally agree was the very first finger-driven touchscreen. ...To outline the jumps and bumps in the touchscreen’s history, Atmel has developed the following infographic (link), which -- in addition to noting some of the more historic milestones -- also includes some of the weirder tidbits of trivia and nuggets of knowledge." via EE Times

Quantum dot technology progresses, ships in LED-backlit LCD TVs "3M, for example, is now using QDs [Quantum Dots] supplied by Nanosys, Inc. to offer a quantum-dot enhancement film (QDEF) a thin, optically-clear sheet with red and green dots that replaces the existing diffuser film in the reflective cavity of an LCD backlight. This packaging, explains 3M marketing development manager Art Lathrop, "not only simplifies integration and protects the dots against flux but boosts efficiency by recycling light emitted in the wrong direction."" via LEDs Magazine

Meet 'Willi', An LCD-Covered Bus "The concept (video) designed by Tad Orlowiski is supposed to make use of transparent LCD screens, which would allow the display of images while simultaneously not interfering with the passengers views. This sounds pretty damn sci-fi, but apparently transparent LCD is a real, expensive technology." via Digital Trends

How Did 3M Create A Display With A Clear View from Any Angle "Multilayer Optical Film is made with such precision that it is viewable from a variety of angles without loss in resolution or clarity. This precision also contributes to its optical efficiency, which reduces power usage. It has become very important for the success of smartphones, says Ouderkirk, because it is one of the key pieces of technology whose primary role is augmented by a secondary function, which is to reduce battery pore consumption. Without it, most smartphones would have much higher battery consumption. But designing this new film was not easy, and required a major advance in the physical understanding of nanoscale materials’ optical behavior. Polymers were already used in high-performance reflectors, fabricated using a physical vapor deposition process that placed thin layers of organic materials. But such films were entirely unsuitable for interference optics." via R&D Mag

How Much Does Sharp's New LED Device Expand LCD Color Gamut Without Lowering Brightness? "Sharp combined a blue LED chip with red and green phosphors made using totally new materials and realized the 90% color gamut on NTSC (CIE1931) standards and a high brightness. With the 0.4mm-thick model for small- and middle-size LCD panels, it is possible to ensure a screen brightness that is only 3% lower than the screen brightness of the LCD panel using yellow phosphors, the company said. And the wider color gamut enables to display video that looks stereoscopic." via Tech-On

How do carbon nanotube-doped liquid crystals result in faster LCDs? "Liquid crystals (LCs) exhibit a phase of matter that has properties between those of a conventional liquid and those of a solid crystal. This means that LCs can flow like a liquid, and at the same time the anisotropic LC-molecules maintain a long range crystalline order. Their unique combinations of liquid and solid-like properties allow liquid crystals to be used pervasively in the electro-optical display technology – known as liquid crystal display (LCD). In new work, researchers have observed that a dilute suspension of a small amount of multi-walled carbon nanotubes (MWCNTs) in a nematic LC (in the nematic LC phase the molecules are oriented in parallel but not arranged in well-defined planes) results in a significantly faster nematic switching effect on application of an electric field." via Nanowerk

How Korean LCD Industry Will Be Impacted By Core Technology for Digital Exposure Equipment "A Korean research team consisting of members from both industry and academia have successfully developed key elements of 8th generation digital exposure equipment, or lithographic devices for flat panel displays, which can be used in manufacturing not only LCD but organic light-emitting diode (OLED) screens. Exposure equipment for flat panel displays was the only device that was not localized among the five key devices to produce displays, which forced local manufacturers to rely solely on imports from other countries such as Japan. As this development will open doors for the local production of exposure equipment, it is expected to bring about an economic ripple effect of over 1 trillion won ($US950 million), including import replacements worth 600 billion won (US$570 million), or 20 to 30 billion won per unit." via BusinessKorea

LCD Jargon: What Are Flat Panel Displays And How Do They Work? "Electro Luminescence (EL) is a device (or display) that utilises a material that generates fluorescence (self-luminous) when a voltage is applied. It has features such as high contrast, wide viewing angles, rapid response, low power consumption, etc. Those who don’t contain carbon molecules are called inorganic EL, and those who do are called organic EL." via Av Max

How To Recycle LCD Displays: UK Company Gets Approval "Electrical Waste Recycling Group Ltd has achieved full UK approval from the Environment Agency to be the world’s first recycling plant to mechanically process LCD Flat Panel Displays (flat screen televisions and monitors). These displays contain mercury and become hazardous waste when they enter the waste stream. Flat panel display recycling, when carried out manually, takes 15 minutes per display, however, the new process operates at a rate of one every six seconds making it faster and safer than any other process in the world. The UK sees one million used flat panel displays entering the recycling market per month." via Recycling Portal

Why E Ink Devices Will Be Getting Lighter: New Display Technology "Fina is a glass based TFT technology that uses a very thin glass substrate to deliver products that are much lighter and thinner than what is possible with standard LCD displays. Fina displays weigh less than 50% of the weight of an equivalent glass based TFT and are less than 50% of the thickness as well. This is particularly important for mobile products requiring larger display areas. A 13.3" Fina display module, installed in the PocketBook CAD Reader, weighs approximately 60 grams." via E Ink

What Is Digital Signage Going To Look Like In 2014? "Video walls can even compete with very large single digital screens. There are still 150-inch plasma displays and LCDs now approaching 100 inches. As awesome as big displays are in their own right, they are limited with respect to their resolutions. With video walls, installers can utilize very high resolutions on each screen — reaching almost 6K by 5K. That's a higher resolution than one can achieve on a single screen. Video walls lend themselves to creativity and diversity, and that's why they will be more experiential in 2014." via Digital Signage Today

Why The Nexus 5 Display Is Synaptics' Calling Card to the Mobile Industry "The ClearPad 3350 technology used in the Nexus 5 features Synaptics' patent-pending In-Cell technology. This new technology allows touchscreen functionality to be present inside of the LCD display, which negates the need for an additional layer of sensors. The benefit is that it allows the mobile device to be thinner, lighter, and more responsive." via Daily Finance

Japan Display to acquire Taiwan LCM maker and establish new subsidiary in China "Japan Display (JDI) has decided to make Star World Technology Corporation (STC), a Taiwa-based manufacturer of LCD modules (LCMs), into a subsidiary of Taiwan Display (TDI), JDI's wholly owned subsidiary, by acquiring approximately 80% of STC's outstanding common shares through TDI. ...The principal objective of TDI is to expand business in the market for small and medium-sized displays, its main business domain, particularly in the China market, which is growing rapidly." via DigiTimes

Are Car Touchscreens Losing Their Appeal? "Jack Nerad, Executive Editorial Director at Kelly Brook Blue, commented to USA Today that it is better to stick to what consumers know best, saying that Ford’s decision to get rid of buttons entirely “may have been a bit overkill”. Consumer Reports has furthermore labelled the interface “distracting”, the fundamental design as “flawed” and the flush, touch-sensitive buttons as “maddeningly fussy and…hard to distinguish.” Frost & Sullivan has taken a more diplomatic line, stating that “OEMs are finding it hard to balance out an offering which provides the latest and greatest features but also assures safety… clearly proving that full touch experience is not yet automotive ready.”" via Automotive World

Boston College Study: How Touchscreen Technology Impacts Shopping Choices ""The Carroll School researchers had separate groups of people surf online for a sweater and a city walking-tour service using a touchscreen, touchpad, and normal computer mouse in one study, and sweatshirts and tents on iPads and laptops in a second study. After choosing a product, participants were asked how much money it would take for them to sell their product if someone else wanted to buy it. Those using the touchscreen wanted almost 50 percent more money for their chosen product than those using the mouse or touchpad laptop. Explaining the reason for such elevated perceptions of ownership, Brasel says, “This is the first evidence that we know of exploring this endowment effect via touchscreen interface. When we reach out to grab a product in the real world, we’ll hold the product in one hand and touch the product with the other hand. So the act of doing that on a tablet mimics our real-world experience much better than when we’re operating a mouse that in turn moves a pointer that is on some unconnected screen we’re not even holding."" via The Boston College Chronicle

How a robot is testing whether humans will find a new touchscreen responsive. "It’s a far cry from the menial work that Oculus’s robot arm was designed for: moving silicon wafers around in a chip fab. But it’s not just a party trick. Intel built Oculus to try to empirically test the responsiveness and “feel” of a touch screen to determine if humans will like it. Oculus does that by analyzing how objects on a device’s screen respond to its touch. It “watches” the devices that it holds via a Hollywood production camera made by Red that captures video at 300 frames per second in higher than HD resolution. Software uses the footage to measure how a device reacts to Oculus—for example, how quickly and accurately the line in a drawing program follows the robot’s finger, how an onscreen keyboard responds to typing, or how well the screen scrolls and bounces when Oculus navigates a long list." via MIT Technology Review

Aviation Displays: Honeywell Touchscreen Research Guides FAA Regulation ""We have a heavy focus on human factors, including the appropriate intended function and functional allocation for touch technology on the flight deck," said Merdich. "Our research, has shown that there are key attributes — technology, location, button size, spacing, menu navigation, etc. — to the implementation of touch that are instrumental toward insuring a satisfying user experience with touch in this unique environment." Focusing on human factors should help to relieve fears expressed by operators and pilots in reaction to previous reports on touchscreen technology regarding inadvertent touchscreen swipes. To address inadvertent touchscreen interactions, Honeywell's researchers and engineers are evaluating the usability of differing touch technologies, such as digital resistive technology, which requires more pressure to change the function of the interface than would a typical swipe on a touchscreen smartphone or tablet." via Aviation Display

How To Reduce electrical noise in projected capacitive touch panel designs "The most common culprit is, of course, the TFT. It’s directly behind the PCAP touch panel and is radiating straight into it. A TFT contains a variety of digital signals which may have frequency components in the hundreds of kilohertz, which is the exact frequency range that can cause problems for a PCAP. The backlight is typically the worst offender on the TFT. When choosing a TFT for a PCAP based project, try to avoid TFTs with CCFL backlights. The inverter used to drive a CCFL is very noisy and may cause localized (i.e. the noise is present directly above the location of the inverter) noise issues on the PCAP. An LED backlight is generally the best option when available." via EDN

IGZO display tech finally makes it to mass market "Low-temperature polycrystalline silicon (LTPS) is another alternative to a-Si that has higher electron mobility and thus excellent image quality, but LTPS is difficult and expensive to manufacture. One of the best examples of LTPS is the new Kindle Fire HDX, which is probably the only device on the market that has a better display than the iPad Air. According to Raymond Soneira at DisplayMate, the iPad Air’s use of IGZO reduces the display’s power consumption by 57% over last year’s iPad 4 — a huge reduction for a single generation." via ExtremeTech

How to build a "stealth" computer display "Brusspup specializes in optical illusion. He noticed that if you completely remove polarizer P1, an LCD display shows essentially uniform illumination with a varying pattern of polarization over the screen. However, as the human eye is not very sensitive to the polarization of light with which it sees the world, an LCD display from which the final polarizing film has been removed appears to be bright and featureless." via Gizmag

Are PC Displays Still Needed? "From the success of crowdfunding for cheap displays, there is clearly a need on the market for low-cost digital screens. The fact that prices for this equipment continue to drop will provide a stimulus to new and innovative uses for displays by businesses, especially by small and midsize companies where budgets are tight. Displays may eventually become a cost-saving commerce solution for advertising and marketing departments." via Midsize Insider

How MIT Invented A Screen That Lets You Reach Through And Touch Things "They call it inFORM. Unveiled this week, the device employs 900 plastic pegs on a square grid that can be raised or lowered to form shapes. A depth camera tracks the shape and movement of the input (your hand, your dog... whatever) and displays it with the pegs." via International Science Times

Why Smartphone Makers Are Racing to Build Flexible Screens "Just as liquid-crystal displays supplanted cathode ray tubes years ago in televisions, Korean display makers are now concentrating their efforts in organic light-emitting diode screens, which offer more vivid colors and can be made even thinner than liquid-crystal displays, since they don't require a backlight. Display makers in Japan and Taiwan have also been experimenting with different types of flexible screens though they haven't been able to reach mass production." via The Wall Street Journal

What is the future of displays? Qualcomm's Toq Smartwatch Displays "The Toq uses MEMS to produce the IMOD effect. Interferometric Modulation creates colors in a different way than LCDS or OLEDS. Essentially, the MEMS that comprise the display have two elements: coated glass on top and reflective membranes on bottom. An air pocket between the two layers is what creates colors depending on what type of electrical charge is applied to the pixel." via ReadWrite

New liquid crystal structure reported by Kent State researchers "A research group at Kent State University has described and documented the structure of a new type of liquid crystal that had been predicted theoretically, but never seen. The new "twist-bend nematic" liquid crystal, one with a spiral twist, was observed by a Kent State research group led by Oleg D. Lavrentovich, Ph.D., D.Sc., trustees research professor of chemical physics and former director of the Liquid Crystal Institute at Kent State. The new type of liquid crystal, akin to a new species in biology, might enable new technologies, ranging from faster-switching display devices to biological sensors, Lavrentovich said." via Record-Courier

Is Ink-Jet Printing the Key to Next-Generation OLED Displays? "Kateeva’s setup—available as of today to display makers—features a movable platform that precisely positions glass panels or plastic sheets large enough for six 55-inch displays beneath custom print heads. Each head contains hundreds of nozzles tuned to deposit picoliter-scale droplets in exact locations to build up the pixels of a display. The company says the tool can be incorporated fairly easily into existing display production lines. Kateeva cofounder and president Conor Madigan says the system, based on the same technology in consumer ink-jet printers, eliminates the need for a step in the conventional manufacturing scheme that increases the risk of defects in the displays." via MIT Technology Review

New chip can detect gestures in front of tiny wearable displays "A fledgling company, Chirp Microsystems is developing a gesture-based operating system to work with a new chip that uses sound, rather than vision, to track the user’s movements. ...Inspired by medical technology, the system uses ultrasound, rather than light, to detect hand gestures within a range of about a meter. The system can sense gestures that don’t occur directly in front of its display, and it uses far less battery power than existing gesture camera-based interfaces: It runs up to 30 hours continuously on a tiny battery." via Singularity Hub

Touchscreen display coating market to see major shift in technology "Indium Tin Oxide (ITO) now has a 95 percent market share for touch-screen transparent conductive coatings. At the same time, shipments of non-ITO films are forecast by IHS to increase 320 percent this year. By the end of 2017, shipments of alternative technologies--such as silver nanowire, copper mesh, silver mesh, silver halide and silver nano particle--will account for 34 percent of the market, reducing ITO's share to 66 percent." via FierceMobileIT

Could Biological Semiconductors Transform Tech Industry? "The semiconductors are known as quantum dots and are made from naturally occurring organic compounds called peptides, short chains of amino acids, the building blocks of proteins. ...In a demonstration, Mr. Rosenman shone a blue light (the backlight in an LCD TV is blue) onto tubes containing different solutions of quantum dots. The tubes lit up in red, green and blue—the constituents of any display. “There is a cost saving of about 10 times compared to other displays,” said Mr. Myersdorf. “The manufacturing process is the same as for making OLEDs.” An OLED is an organic light-emitting diode, commonly found in some smartphones and TVs." via The Wall Street Journal

New Twists On Autofocus, Multitouch, And Energy Harvesting "Qeexo has not built a new MEMS device; rather, it’s using information from the accelerometers already built into smartphones and tablets in a new way. ...Qeexo’s software analyzes the vibration generated when you touch the screen and determines whether you’re using your fingertip, knuckle, fingernail, or a stylus. Apps can then use that information to allow different types of touches to perform different function—a knuckle swipe, for example, could highlight text instead of scroll down the page; a fingernail could bring up a menu. It seems simple, but it’s not so easy to implement: Schwarz said she’s met with manufacturers who aren’t interested at first, then come back and tell her that they tried and failed to replicate the technology and are now ready to talk." via IEEE Spectrum

How To Add a Touch Interface to your Hardware with Touch Board "Want to create an interactive design with touch interface? Well, the Touch Board may be just what you are looking for. Arduino compatible, the Touch Board comes with 12 capacitive touch channels and will respond to anything conductive that is connected to one of the channels. You can turn on a light, ring a doorbell, or even play midi music, all from your very own Touch Board." via Engineering.com

F-35 Program Stops Alternate Helmet Display Development "In a review of the F-35’s flight-test progress in 2011, the Department of Defense identified the HMDS as one of several program risks. It found that the helmet system was deficient in the areas of night-vision acuity, display jitter during aircraft buffeting and image latency from the F-35’s electro-optical distributed aperture system, which combined detracted from mission tasks and the use of the display as a primary flight reference. The Gen 3 helmet “will include an improved night vision camera, new liquid crystal displays, automated alignment and software improvements,” according to the JPO" via AIN Online

Samsung Display begins LCD production in China "Samsung Display, a unit of Samsung Electronics Co, and domestic competitor LG Display are both building multi-billion dollar flat-screen plants in China, to help them compete more effectively against little-known Chinese rivals. Chinese companies such as BOE Technology Group and TCL Corp's LCD unit CSOT are undercutting the world's two biggest LCD makers and winning market share with robust sales to local TV manufacturers." via Reuters

Apple's War on Pixels "Commodification is an inherently boring process, particularly when it comes to technology: over time, products that were once unique and expensive become less so. That process has pushed HDTVs, wireless routers, and Bluetooth speakers into living rooms en masse as the technologies behind them have become more and more generic. One technology most visibly marked by commodification is displays—in particular, high-resolution displays so packed with pixels that human eyeballs cannot perceive the individual dots that make up the image" via The New Yorker

The new manufacturing tech that will bring high-resolution displays to every device "Applied Materials’ three new manufacturing machines should help cut costs by improving quality control and flexibility at multiple points in the production process. The new AKT 55KS PECVD is a Plasma Enhanced Physical Vapor Deposition system that’s designed to better control the amount of hydrogen gas inside the manufacturing chamber, allow for a more uniform distribution of deposited material, and eliminate defects. The other two machines — the AKT PiVot 25K DT and PiVot 55K DT are essentially the same system, but built at two different sizes." via ExtremeTech

Augmented reality system makes cars see-through "Michel Ferreira and his colleagues at the University of Porto in Portugal developed the See-Through System, which uses a lightweight heads-up display to look "through" a truck up ahead. The system works by looking through a camera that records the trailing driver's perspective. Software recognises the back of the lead vehicle, and replaces it with a video feed from a webcam mounted on that lead vehicle." via New Scientist

Display database for engineers Search thousands of display panels by multiple characteristics and compare results side-by-side using the display database multisearch.

Mitsubishi Shuts Down Consumer Video Division "Mitsubishi was always a big player in the RPTV category...,and near the end of its run it created some truly gargantuan rear-projection displays. But the market moved on, wanting flat panels instead of floor standers, and unfortunately Mitsubishi couldn’t refocus fast enough to keep its head above water. So if you liked Mitsubishi’s gear, I’d watch big resellers and liquidators for some serious discounts between now and the holiday buying season." via Technology Tell

Technology to Humanize the Brand "In today’s virtual mannequins, high-resolution optics project a video onto a screen, usually made of cut glass or acrylic shaped in the silhouette of the mannequin speaker and coated with a semi-transparent film. Viewed from the side, the mannequin is only about one cm thick; viewed from the front, the cut-out resembles a person. Improvements on current technology are bringing these mannequins to life. Light efficient projection technology is increasing brightness from today’s average 3000 to 4500 lumens to well beyond 6000 lumens so that the image is crisp and distinctive, even in a brightly lit room." via Wired

Disney tech lets users feel 3D objects on flat screens "Ordinarily, when we feel a bump as we're sliding our finger across a smooth surface, we do so because the increase in friction created by the bump causes the skin in our fingertip to stretch ever so slightly. In order to simulate that friction, the Disney team uses a conductive display in which the electrostatic forces between the finger and the glass can be modulated by applying more or less voltage to the screen." via Gizmag

Semiconductor Will Help Develop Hi-Def Flat Panels "Researchers at the National Institute for Materials Science have developed a pixel switching semiconductor, which will be the key to driving next-generation displays by using an oxide film with a new elemental composition. ...The research results are expected to be effective not only for reducing the power consumption of displays which consume about half of the power in rapidly diffusing smartphones, but also for achieving higher frequencies to realize higher-definition TVs." via Controlled Environments

Does test equipment really need knobs and displays? "Put your tablet wherever you wish. Or remote the display to your laptop that is supporting some humungous monitor. Why settle for the fixed sizes of displays offered by vendors when you can buy high resolution displays at your local electronic retailer larger than your entire lab bench if you wished?Will engineers accept the remote display concept?" via EDN

A True Revolution in Display and Touch-screen Manufacturing Begins "Cambrios (Sunnyvale, California) announced the formation of TPK Film Solutions, Ltd. (TPKF), a joint venture with TPK, the world’s largest touch solution provider, and NISSHA, a leader in film-based touch sensors. TPKF’s mission is to “produce ClearOhm silver nanowire-based film in a roll-to-roll process allowing original equipment manufacturers (OEMs) to bring to market cutting-edge touchscreens for new products and applications worldwide,” Cambrios announced in its press release. ...All of this may not sound too exciting until you understand not only that transparent conductors are essential components of most displays and touch screens, but also that ITO has significant limitations." via HDTV Magazine

Nvidia Ends Screen Tearing With G-Sync Display Technology "Conventional LCD monitors have fixed refresh rates, typically 60hz, which the GPU must work with, but with G-Sync, a module goes inside the monitor that transfers control of the refresh rate to the GPU. Because the display adapter controls the timing, the two are always synchronized, eliminating screen tearing without sacrificing performance." via The Escapist

Honeywell Nearing Launch Of Touchscreen-Enabled Avionics "Along with qualitative assessments of the pilots’ workload, researchers used electromyogram measurements of muscle activity to gauge the pros and cons of mounting locations and touch technologies. The researchers confirmed that the best fit for touchscreen displays on large flight decks for high-end business jets or air transport aircraft is on the center console, or pedestal. “From a pilot workload perspective, if you put touch there, that’s the best place for it. In a smaller flight deck, pilots are used to looking at bezel buttons and knobs on the forward displays, so touch makes more sense there.”" via Aviation Week

Robotic testing finds touchscreen inaccuracies at edge of iPhone display "Using a robotic finger and a specialized suite of test software, Finnish automated testing company OptoFidelity found that Apple's latest handsets accurately detect touch inputs only across a small swath of their displays, roughly equating to the location of the on-screen keyboard. The iPhone 5s and 5c, according to the company, suffer from "extremely bad" touch performance near the edges of the display." via Apple Insider

New multi-touch sensor is customizable with scissors "Together with researchers from the MIT Media Lab, they developed a printable multi-touch sensor whose shape and size everybody can alter. A new circuit layout makes it robust against cuts, damage, and removed areas. The researchers have presented their work at the conference “User Interface and Technology” (UIST) in St. Andrews, Scotland. The sensor remains functional even when cut to a different shape." via R&D Mag

Tourist site desperate to stop graffiti adds vandal-friendly touchscreens "Officials in Wuhan's Yellow Crane Tower Park are determined to stop name-etching vandals once and for all, and have rolled out a series of graffiti-welcoming touchscreen displays. Now well-behaved and asshole tourists alike can enjoy the thrill of leaving their marks on priceless antiquities." via Shanghaiist

Existing Inside the Screens "In his TED Talk, Reach into the computer and grab a pixel, Dr. Lee shows some current projects and discusses future possibilities. The talk begins with discussing the boundaries between the user and the screen, and throughout the talk the boundary gets smaller until it no longer exists." via Engineering.com

Wheel-Shaped Molecules Better For Displays "Whereas the usual rod-shaped LEDs can trap up to 80 percent of light generated because light flows from them in only one direction -- known as polarization -- Lupton and his team made a molecule that is "perfectly symmetrical, and that makes the light it generates perfectly random,” he said in a university news release, noting the new organic molecule is known as OLED." via International Business Times

Worlds Largest e-Paper Sign Displayed at UN Headquarters "e-Ink has set a worlds record for the latest e-Paper sign that is installed at the UN Headquarters in New York. The eWall is an intricate combination of architectural, display and network engineering. It stands about 6 meters wide with 231 tiled 7.4″ displays arranged in a grid of 33 displays across by 7 displays high. With an overall resolution of 26,400 x 3,360 pixels, it is perfect to read at long and short distances." via Good Reader

Aerial Imaging Plate turns holograms into touchscreens "Much like a low-quality monitor with a very narrow viewing angle, the AIP’s holographic effect can only be viewed from a very specific location in relation to the projected image. To onlookers, it appears as a regular flat surface, but to a person standing in the sweet spot, the image looks as though it’s floating in the air. In what may seem like a classic case of “it’s a feature not a bug,” Asukanet feels the specific viewing angle requirement is appealing, perhaps as a privacy feature, even though onlookers can see what’s happening on the flat display." via ExtremeTech

Visually stunning art performance using cutting edge display technology "'Box' explores the synthesis of real and digital space through projection-mapping on moving surfaces. The short film documents a live performance, captured entirely in camera. Bot & Dolly produced this work to serve as both an artistic statement and technical demonstration. It is the culmination of multiple technologies, including large scale robotics, projection mapping, and software engineering. We believe this methodology has tremendous potential to radically transform theatrical presentations, and define new genres of expression." via Bot & Dolly

South Africans Develop ‘Digital Laser’ ""Our digital laser uses the LCD as one of its mirrors that is fitted at one end of the laser cavity. Just as with LCD televisions, the LCD inside the laser can be sent pictures to display. When the pictures change on the LCD inside, the properties of the laser beams that exit the device change accordingly," said professor Andrew Forbes, leader of CSIR's mathematical optics research group, where the work was done. Forbes, who in March became the first South African inducted as an SPIE Fellow, led the team, supported by postdoctoral fellow Dr. Igor Litvin and doctoral students Sandile Ngcobo and Liesl Burger. " via Photonics.com

Tetrapod quantum dot LEDs could lead to cheaper, better HDTVs "Manufacturers are seeking to "print" tetrapod quantum dots onto backplane films in liquid crystal displays (LCD) for brighter images, larger screens and a wider gamut of colors to deliver a new visual experience in image technology. Thinner, lighter, brighter and less expensive QD-LED displays, including portable and flexible devices, will offer almost infinite contrast levels, deep black levels and high light output with no motion blur or field-of-view issues." via Engadge

LCDs enter the fast lane "The molecules in a nematic liquid crystal do not line up perfectly with one another, resulting in a finite distribution of orientations around that of the director. The magnitude of this variation affects the phase of light passing through the liquid crystal and as a result its intensity. Since an applied electric field changes that magnitude, it also changes the amount of light passing through. Physicists have known for decades that such an effect ought to exist. What Lavrentovich and co-workers have done is to prove experimentally that it does exist and that it takes place over much shorter timescales than the relaxation of molecular reorientation in conventional LCDs." via Physics World

It explains how competing technologies in LCoS projectors compare in terms of brightness, performance, durability and reliability." via Azom

UCLA creates flexible OLED display that can be stretched to double its normal size, folded in half "The material functions in this way thanks to a novel layered construction. The light comes from a single layer of electroluminescent polymer, which is held between two transparent elastic composite electrode layers. The electrodes themselves are a notable advancement. A lack of stretchable electrodes has been one of the problems holding this kind of display back." via ExtremeTech

The PenTile RG-BW LCD display on the new Note 10.1 consumes 30% less power "The problem is a lot of the backlight is absorbed and turned to heat, and thus wasted. To allow more light through, Samsung added a “white” subpixel to the arrangement, though a better term would be “clear”. This subpixel doesn’t absorb light like the other three types and serves to increase brightness, especially when it comes to displaying the white backgrounds that are prevalent on the Web." via Android Authority

LG, Samsung Display feel heat from little-known Chinese LCD makers "While the Korean giants were busy developing next-generation organic light emitting diode (OLED) TVs, little-known Chinese companies have started selling a type of display that are sharper than the standard LCD and cheaper than OLED. Say hello to ultra high-definition (UHD) displays. ...As Korean display makers work on their response to this growing menace, Chinese UHD makers are enjoying the fattest margins in the industry." via Reuters

Filthy touchscreens carry more germs than toilet seats "Firms like Apple actively discourage users from using detergents on their touchscreens because they can damage them. The presence of the germs simply shows that touchscreen users fail to wash their hands properly, while few people bother to clean the devices and keyboards." via Business Report

Touchscreen displays cost how much?!?! "If your boss or client is still clinging to the idea that a cheaper option would suffice, perhaps we should move onto the issues of design and usability. Touch overlays, although seemingly a lesser investment, actually introduce more costs and opportunity loss due to several factors. ...The best integrated touch displays are designed to be beautiful and compact. Each monitor should have its own metal design to ensure the best fit, form and function." via Digital Signage Today

Movable Display is Made of Paper "Human organs shimmer in red on a sheet of paper displaying a longitudinal view of the human abdomen. The spinal column and pelvic bones form contrasting yellow islands. As the sheet of paper is bent downwards at the ends, the bones appear to come into the foreground while the soft tissue recedes. What appears to be science fiction at first glance, is the result of the “Flexpad” research project developed under the leadership of Jürgen Steimle in the Media Lab at the Massachusetts Institute of Technology in the U.S. and the Max Planck Institute for Informatics in Saarbrücken, in cooperation with Kiel University. " via Laboratory Equipment

Wonder Material Ignites Scientific Gold Rush "One factor holding graphene back is cost. Some U.S. vendors are selling a layer of graphene on copper foil for about $60 a square inch. "It needs to be around one dollar per square inch for high-end electronic applications such as fast transistors, and for less than 10 cents per square inch for touch-screen displays," estimates Kenneth Teo, a director at the Cambridge unit of Germany's Aixtron that makes machines to produce graphene." via The Wall Street Journal

Qualcomm Toq: The Anti-Galaxy Gear Smartwatch "Qualcomm has been working on its Mirasol technology for years. To date, it hasn't been very successful in winning adoption of the low-power screen tech. The Toq could change that. The Toq is probably the highest profile proof-of-concept Qualcomm could have created to show off its mobile screen cred. Thanks to the screen technology, Qualcomm says the Toq can go several days between charges." via InformationWeek

Research of highly rugged and lightweight liquid crystal displays "Together with national and international industry partners, scientists at the University of Stuttgart have started the development of very robust and extremely lightweight displays within the research project LiCRA. Instead of common glass substrates these displays are based on plastic foils what makes them flexible. The overall market for rugged displays is estimated to a total of seven billion (milliard) US$ until 2015." via Printed Electronics World

A Faster Liquid Crystal "The brightness of a pixel in a typical flat screen display is regulated by an electric field that controls the orientations of molecules of a liquid crystal. In Physical Review Letters, researchers report a much faster way of using the field to change the state of the molecules and alter the light transmission. Although the measured effect is small, it is thousands of times faster than the conventional technique and might be increased enough to allow new design options for displays." via APS Physics

LG Display Develops World’s First Intel® WiDi Enabled LCD Panel for Monitors "LG Display succeeded in developing a panel that provides Intel® WiDi solution by building in a key chipset directly into the LCD module. With this cutting-edge LCD panel embedded with Intel® WiDi solution, LG Display enables users to enjoy quality images with an easy and convenient access to Intel® WiDi technology without the use of additional devices, as well as facilitate OEMs and monitor makers nimbly and cost-effectively adopt this advanced technology." via LG Display Newsroom

Taiwanese take early lead in UHD LCD-TV panel market ""Most television brands are counting on UHD sets-with their astounding 3,840 by 2,160 resolution-to rejuvenate sales," said Sweta Dash, senior director, display research and strategy for IHS. "That's why the Taiwanese suppliers are focusing heavily on meeting early demand for UHD LCD panels. Meanwhile, South Korean suppliers LGD and Samsung have turned their attention to a different technology: the active matrix organic light emitting diode (AMOLED) panel, which they believe represents the next generation of television."" via CIOL

Apple bucks the PC OEM trend and increases demand for LCD panels "In real terms, panel shipments in July totaled 14.9 million units, down from 19.3 million during the same month in 2012, claims a new report by IHS. ...Of the top panel buyers only one company increased demand, and that was Apple. According to IHS, the Cupertino company increased panel demand in order to be able to keep up with demand for the MacBook Air." via ZDNet

Gesture-based UI boosts proximity sensor market ""The Galaxy S4 from Samsung Electronics represented the first major push towards gesture interface capability in a handset when the smartphone was released this year," said Marwan Boustany, senior analyst, MEMS & Sensors, for IHS. "This is a step that others in the industry are likely to follow, thanks to the rising availability of gesture solutions from suppliers like U.S.-based Maxim Integrated Products and soon from both Japan's Sharp and Taiwan-based Capella Microsystems."" via EET India

Challenges involved in modernising an aircraft's avionics suite "For example, two H-model C-130 Hercules aircraft, originally built in the 1970s, and two stretch variants built in the 1990s, recently underwent extensive avionics modifications in Cambridge. At the heart of the programme was the installation of a Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) compliant Flight Management System (FMS) and display and surveillance systems. The display system consists of six flat panel displays which incorporate the functionality of the many original electromechanical displays and the surveillance systems, including Enhanced Traffic Alert and Collision Avoidance System (ETCAS - which is mandatory for aircraft entering controlled airspace) and an Enhanced Ground Proximity Warning System. However, the aircrafts' original analogue autopilot systems had to remain, which meant employing signal converters so that old could interface with new." via New Electronics

Implications of passive stylus on large capacitive touchscreens "Passive stylus detection is a complex problem for touch engineers, with the root of the problem being the stylus paradox. The stylus paradox is that the signal profile for a passive stylus is several times smaller than that of a normal touch inut, but the fine point of the stylus makes the user believe that it will be more accurate. Accuracy and linearity are proportionally related to the signal to noise ratio of the system." via EDN

Two new features for electrophoretic displays? "The new Amazon Kindle Paperwhite will be the first product to incorporate Carta displays. Compared to Pearl, Carta promises higher reflectance and better contrast. What attracted my attention however was something that went completely unnoticed: on the specification sheet, E Ink now says an image update can be done in only 120 milliseconds." via Printed Electronics World

Researchers explore haptic technology beyond touchscreens "One of the critical challenges in developing touch systems is that the sensation is not one thing. It can involve the feeling of physical contact, force or pressure, hot and cold, texture and deformation, moisture or dryness, and pain or itching. "It makes it very difficult to fully record and reproduce the sense of touch," said Wang. As noted in the article, there has been significant progress on the development of flexible and sensitive pressure sensors, as well as tactile feedback displays for specific applications such as for remote palpation that could be used during laparoscopic surgery." Phys.org

When do interactive touchscreen displays make sense in the newsroom? "What most newsroom touch installations lack, is a clear vision of how this technology can be important for their audience. In many cases, engineers seem to have simply transitioned traditional on-air graphics onto a touch screen. Instead of some off-camera person triggering graphics on cue, the host triggers the graphics by touching points on the display. This can be pointless or profound depending on how it is implemented." via CGW

World-first smart fabric screen-printed electroluminescent watch display "The watch display is printed directly on to fabric to achieve the world’s first printed smart-fabric watch. The watch is printed layer by layer using screen-printable pastes with electronic functionality such as conduction, insulation and electroluminescence. The electroluminescent displays were printed by Marc using the thick-film printing facilities in the Southampton Nanofabrication Centre cleanroom." via University of Southampton

The LG G Pad will use GF2 display technology "One of the first manufacturers to use a film-based touch panel was Apple, on the iPad mini. According to the WSJ, the same tech will allow the Cupertino company to make the iPad 5 lighter and thinner than previous generations. If this report from Korea Herald is accurate, LG will benefit from the same advantages by using a GF2 film-based panel on the G Pad." via Android Authority

EU Adjusts Tariff On Flat Panel Displays "At present, a duty rate is applied on imports of flat panel displays not used exclusively for automatic data-processing (ADP). The reform will mean that displays using signals from ADP machines will be able to receive duty free treatment on an autonomous basis." via Tax-News

Optical touchscreens benefit from compact, high-power infrared LEDs "Optical solutions are now on the march, particularly for large displays. Their benefit lies in the excellent image quality because they do not need any special coatings that absorb a certain percentage of the backlighting. They can detect any type of pointer or stylus and even fingers in gloves because they are not reliant on the conductivity of these objects. Optical designs are also not at all sensitive to scratches and, depending on the power of the emitters, can be used for any size of screen." via LEDs Magazine

'Fake skin' computer touchscreen may aid cancer diagnoses "Ms Jess Tsimeris, of Bruce, is working with electromagnetic forces, using magnets to raise and lower soft latex surfaces. She has created soft touch surface with lumps that can be moved around and made firmer, or less firm. ...Supervisor Tom Gedeon said research in the field could also lead to more secure key pads at ATMS, using a squishy surface where a user was identified by how hard they pushed." via Canberra Times

Elon Musk demonstrates Iron Man style fabrication interface "Armed with a Leap Motion controller and few of today's mainstay 3D display technologies, Musk really has created something that roughly resemble's the interactive displays in Iron Man — though it admittedly looks like a Mark 1 model. In the video below, Musk takes you through the evolution of his interface." via DVICE

Apple researching display tech that can independently adjust appearance of UI elements "To efficiently recognize and change each element, the system looks at color saturation, or more specifically, saturated pixels versus non-saturated pixels. In one embodiment, the non-saturated pixels are associated with areas that don't hold active content, and therefore show the most change when display adjustments are made." via Apple Insider

NFC technology can be used to wirelessly power an E-ink display "NFC uses inductive coupling to provide power to passive tags and the E-ink display uses this to its advantage with the help of a wireless power harvester microchip and a 1mAh battery. Don’t expect massive power without wires just yet but it’s enough to power the 2.7-inch display with enough stored energy to cycle through images when not paired with the phone." via TechSpot

The PC monitor is dead. Meet the new smart monitor. "Bob Wudeck, associate vice president of strategy and business development at BenQ, says that the company has been forced to rethink the concept of a monitor, whether it be gaming monitors optimized for StarCraft or adding intelligence to the traditional display. 'The traditional model is a display that a desktop or notebook can plug into,' Wudeck says. 'We don’t think that’s going to be the case. We think that in the future, you’ll have more media content on your phone, and you’ll share more of that from your phone, than from a desktop computer,' Wudeck adds. 'And that’s something that we can develop a product around.'" via PCWorld

LG makes world’s thinnest, highest pixel density smartphone LCD ever "Displays continue to improve, though, as LG has proven with the production of a 5.5-inch 2560×1440 LCD with 538 pixels-per-inch. The LCD is the first mobile display to reach that resolution, and is also the thinnest, measuring in at a mere 1.21mm." via ExtremeTech

Breaking Google Glass Into Pieces: The Costs of Production and Likely Retail Price "'The Himax FSC LCOS [Field Sequential Color, Liquid Crystal on Silicon] requires both a display device and normally a 1-chip ASIC controller.... Figure the controller costs about $2 to $3, but this would go to near zero if the functionality was integrated into other chips in the system,' Karl Guttag tells Minyanville. 'The LEDs for illumination are about $2, and then the films for homogenizing/spreading the LED light and polarizing with packaging are another $2 to $3. I would guess the optics, including the beam splitter in front of the eye, are on the order of $5. When you total up the display plus controller, illumination LEDs and films, and the optics, the total cost is probably about $25, plus or minus $5.'" via Nasdaq

Next-Generation Displays: The Reality of Manufacturing Sets In "Amorphous silicon, with an electron mobility of about 1 cm2/Vs, served LCDs well for years but isn’t suitable for the new displays. Laser annealing of amorphous silicon to turn it into a polycrystalline form, typically in the range of 50 to 150 cm2/Vs, has been the mainstay for high-resolution mobile display manufacture. This process adds costs, however, and does not scale up well." via IEEE Spectrum

Shell 3-D Visualization Lab Offers Detailed Views on Energy-Related Research "For academics, students, engineers, oil and gas drillers, geologists and other scientists, the new Shell 3-D Visualization Lab in the University of Wyoming’s Energy Innovation Center (EIC) has the ability to image detailed 3-D models of land surfaces, the subsurface, molecules and more -- a view that allows these entities to share the same frame of reference. ...The visualization center also includes an IQ-Station, which is essentially a portable, immersive environment that contains a desk with a computer and three moveable display panels. Researchers can sit at the station and don 3-D glasses to review models on a smaller scale. The visualization center also contains a six-panel, two-dimensional video wall that can be used to view any images at high resolution, including 3-D images generated in the CAVE. Both can be used for many interdisciplinary projects, Shader says." via University of Wyoming

A Printing Process to Make Wall-Sized Displays "Adapting conventional printing technology, researchers have developed a way to rapidly and inexpensively make uniform arrays of high-performing transistors out of carbon nanotubes on flexible plastic sheets. The process could eventually lead to a tool for manufacturing large-area, low-power sensor arrays and displays." via MIT Technology Review

The Quest to Touch Virtual Objects "Brownlow says, 'Proximity interfaces are being developed where, as you bring your fingers towards the screen, the screen has a predictive ability of what you are about to do and you can then interface with the screen without actually touching it.' As 3D evolves there will come a point where the user will want to interact haptically with these images. " via Gizmodo

Gulfstream’s Enhanced Vision System (EVS) II and Head-Up Display (HUD) II for the G280 certified by FAA "EVS II captures actual, real-time images of an aircraft’s surroundings using an infrared camera mounted in the nose. The HUD II uses a LCD to project images onto a transparent combiner in the pilot’s forward field of view, and integrates the images with flight guidance information." via Aviation Today

Kickstarter campaign for LED display "Two years in the making, LEDgoes is much like the kind of scrolling screens seen at convenience stores displaying the worth of this week's Lotto, or those seen in front of stock exchanges displaying real-time quotes. However, LEDgoes’ modular design allows the user to make the display practically any length from just one, 5x7 LED matrix panel wide, all the way up to sixty-four panels in total. An even longer length could be attained through software control. ...The Kickstarter officially ends on Sep. 9th at 11:40 PM CDT." via PRWeb

Shifting Apple product specifications to heap pressure on manufacturers "Reports indicate that Apple is set to adopt Japan-made In-Cell, and indium tin oxide (ITO) coated display panels for the company's upcoming products to be released this fall. With Apple's current products nearing the end of their life cycles, including market mainstays such as the iPhone 4, iPhone 4s, and the 9.7-inch early generation iPads, Taiwan-based panel suppliers are poised to be affected by the switch." via The China Post

The future of touchscreens revealed: bigger, cheaper, bendier "But there is a cheaper and less environmentally harmful alternative [than ITO], developed by MIT biochemist Dr Angela Belcher and inspired by the multi-layered formation of abalone shells. It uses silver nanowires scattered over a sheet of plastic. Take two layers of plastic coated with very long, very thin silver strands (or even one sheet coated on both sides) and you have a capacitive touch sensor that's thinner, lighter, more flexible and much easier to manufacture than the ITO sensors." via TechRadar

Electronic Skin Lights Up When Touched "A team of researchers at the University of California, Berkeley, has developed the first user-interactive “electronic skin” that responds to pressure by instantly emitting light. ...Javey, who has been working on developing the e-skin for the past five years, has high hopes for his new material. He’d like to create user-interactive wallpaper or a dashboard that responds to cues such as the driver’s eye or body movements." via IEEE Spectrum

Can touchscreens save you from carpal tunnel? They might actually be worse "Cynthia Burt, Injury Prevention Division Manager at the UCLA Office of Environment, Health and Safety, believes that the inherent nature of laptops make them less than ergonomically sound due to the relatively fixed screen and keyboard positions. This is amplified with a touchscreen laptop because, as she explains, there is a difference between optimal visual difference and optimal reach distance. 'We recommend that people have an 18- to 20-inch envelope in front of them for optimal reaching,' Burt told us." via Digital Trends

What Makes a Good Gesture Control "Phones rely on prompts that are supposed to teach you gestures step by step. But the issue is that human beings have only a limited capacity, depending on their needs, for this sort of tutoring. If we don’t learn the gesture quickly, we’ll quickly shut off the annoying prompts and fail to learn the gesture, says Yaro Brock, co-founder of Cookie Jar UX and a longtime user-experience researcher." via Bloomberg Businessweek

How An Amputee Built The World’s First Functional Prosthetic Finger for Touchscreens "One of MacDuff’s most critical design considerations hardly existed 10 years ago and is now somewhat of a holy grail in prosthetics: making the finger touch-screen-friendly. This had become, after all, one of the most important everyday functions of our fingers. RCM has such a next-generation upgrade to the BPF in development. Bengtsson tells Co.Design they’ve "already identified and tested the material" that can successfully mimic human skin and heat conductance. " via Fast Company

The economics of LCD demand "Reading the news, I get the sense LCDs are knocking on everyone’s door, as panel makers seek to enter every conceivable market. The IHS report notes how price competition in conventional audio systems for checking who’s outside your door leads to interest in new value propositions, such as video and audio surveillance, but that implies highly elastic demand relative to price. A rising demand for door-mounted LCDs requires falling prices." via Display Central

Touch Screen IDs Users via Fingerprints "Entering usernames, passwords, and pins is generally seen as sufficient security for desktops and mobile devices, but things become much more complicated when computers are used by multiple users, especially simultaneously. “Keeping track of who is doing what is a key element for collaborative interactive systems,” says Holz. “We have now created a touch screen that accomplishes this unobtrusively for every touch users make. Incorporating the ability to do this securely and seamlessly opens up a wide range of new applications.”" via MIT Technology Review

Amazon is working on displays that Apple and Samsung can’t match "And with his acquisition of the Washington Post, Bezos has a new incentive to breach new heights in displays—something as light as paper but infinitely more versatile. Bezos has said before that he thinks print is going away but journalism is forever, so it’s hard to imagine that he acquired a print newspaper with the idea that it would continue to be delivered in that medium. Other companies are also trying to turn electrowetting display technology into a viable business, so it seems that, like the development of the LCD display, which began in the US but was not perfected until the technology was acquired by Korean companies like Samsung and LG, this is the sort of technology that could take a long time to develop and will eventually give rise to an ecosystem of competing manufacturers." via Quartz

Mitsubishi expands Industrial TFT sales efforts "This announcement follows the acquisition by Kyocera Corporation of Optrex Corporation, one of Mitsubishi Electric’s sales channels for industrial TFT displays. Effective immediately, Mitsubishi Electric Corporation will replace Optrex’ sales structure in Europe with its own Mitsubishi Electric Europe sales and customer support network." via Evertiq

Low Power with High Contrast LCD Displays "If your next portable battery project involves the need for a high contrast low-power (microwatt range) LCD display and you need it now, read on. Occasionally an existing technology is improved to push components into new usage areas. Sharp has done that with the monochrome LCD display, pushing it into microwatt power consumption territory while approaching e-ink display contrast levels. Coupled with pixel memory, they are call memory LCDs." via ENGINEERING.com

A telescope for the eye: New contacts may improve sight "The new lens system developed by Ford's team uses tightly fitting mirror surfaces to make a telescope that has been integrated into a contact lens just over a millimeter thick. The lens has a dual modality: the center of the lens provides unmagnified vision, while the ring-shaped telescope located at the periphery of the regular contact lens magnifies the view 2.8 times. To switch back and forth between the magnified view and normal vision, users would wear a pair of liquid crystal glasses originally made for viewing 3-D televisions. These glasses selectively block either the magnifying portion of the contact lens or its unmagnified center. The liquid crystals in the glasses electrically change the orientation of polarized light, allowing light with one orientation or the other to pass through the glasses to the contact lens." via EurekAlert

Samsung to Buy Germany's Novaled "Despite continued difficulties in producing OLED screens, Samsung has been heavily investing in the technology. It aims to develop expertise in the area to get an edge against rivals elsewhere in Asia, who won't catch up on the technology as fast as they did with liquid-crystal displays. "We're continuously widening the technological gap between (Samsung) and rivaling companies," Robert Yi, head of investor relations at Samsung Electronics said in July. He said the company aims for another technology "leap" with diversified OLED applications, including flexible displays." via The Wall Street Journal

Display Glass Slimming Technology Report 2013 "Reducing the thickness of a glass substrate to cut its weight has proven to be the most effective way to make a flat panel display thinner and lighter. However, if a glass substrate used in the TFT or cell manufacturing process starts off as a thin sheet, it runs into many difficulties because of the variables arising from the LCD module, or OLED manufacturing process. Thus, it is essential to slim the glass substrate through chemical and physical methods at the time when the cell production process is completed. This process is called glass slimming." via Displaybank

AquaTop turns water into a touchscreen display "A projection system called AquaTop uses water as an interactive display, allowing users' limbs to freely move through, under, and over the projection surface for a more immersive experience. The prototype setup, created by a team of engineers from Tokyo's University of Electro-Communications, projects games, movies, and photos (or, presumably, e-mail and spreadsheets, but they're not as much fun) onto a liquid surface made cloudy with an opaque powder." via CNET

Oxide semiconductors: where do they fit in the changing display industry? "Oxide semiconductor TFT technology is an emerging option which ticks many of the right boxes. They have high mobility, which makes them suitable for OLED, 3D and on-board processing. They have wide-bandgaps therefore they can also be transparent. Their high mobility enables lower aspect ratio and smaller pixels, and therefore lower consumption and higher resolution." via Evertiq

Q&A with Harman: Automotive head-up displays "As the HUD projects images on to the car's windscreen, there can be severe limitations on the amount of windscreen space available for projecting directional images. Depending on the car's design, this can hamper the functionality of the HUD. As the technology develops, we expect to be able to overcome such an issue in the near future. In scenarios where a HUD may not be appropriate, a second screen in the driver's line-of-sight can be used to display a real-time image of the road interlaced with information, graphics and navigation instructions provided by the Augmented Navigation system." via just-auto

Harvard researching how to improve displays and digital imaging "A second study involving Zickler investigates a new type of screen hardware that displays different images when lit or viewed from different directions. By creating tiny grooves of varying depths across the screen’s surface, Zickler’s team created optical interference effects that cause the thin surface to look different when illuminated or viewed from different angles. The paper essentially asks, “If I know what appearances I want the screen to have, how do I optimize the geometric structure to get that?” Zickler explains.via Harvard

The North American Display Business Environment "For the most part, the manufacture of display panels takes place outside North America, with the lion’s share of fabs in Asia. But there is display manufacturing of a different kind in North America – display integration. Says Semenza, “These are opportunities where some kind of customization is required – in the medical, military, and automotive markets, for example.” Such customization includes optical bonding, rugged packaging, light-enhancement films, enhanced backlights, and so forth for a wide variety of applications. Examples of these are adding displays to autos and building units and integrating displays for the medical, military, and industrial markets, with the latter including digital signage, public-access kiosks, ATMs, checkout systems, machine control, and oil and gas exploration as well as mining applications." via The Society for Information Display

Maintaining good touchscreen user experience "Capacitive touchscreens operate by driving a transmit voltage into the sensor panel on the device that creates a signal charge. ...The main problem with larger screens is that the transmit voltage has more surface area to cover and the resistance and capacitance of the sensor increases. ...The transmit operating frequency affects signal settling, refresh rate and power consumption. The goal is to determine the highest transmit operating frequency conditions for a consistent touch response across the panels while minimising scan time and power." via EET Asia

Multi-Touch Industrial HMIs "The ultimate promise of multi-touch technology is that it will make workers more productive. American Industrial Systems has a whitepaper that might be interesting if you want to learn more about the evolution of this technology and the specific advantages it offers for industrial control. A Beckhoff video might also be interesting as an introduction to the technology. It provides a visual demonstration of how multi-touch technology is being implemented for industrial control." via DesignNews

Indium tin oxide, what makes touchscreens touch-sensitive, is almost gone "Some manufacturers are already planning on incorporating ITO alternatives into their devices. Foxconn might begin using carbon nanotubes in the non-Apple devices it makes by the end of 2013, and Samsung is working on prototypes that use graphene, according to Martinez. “There’s lots of R&D to be done though,” Martinez said." via GigaOM

Crowdsourcing with digital signage ""Our studies suggested that people walk up to public displays not knowing exactly what they want to do and usually to kill time. So we tried to find a way to tap into that," he says. ...Vassilis says such displays could be used to tap local knowledge, such as the best place to walk a dog, the meaning of some confusing signage, or what bands are playing in town." via NewScientist

Lack of critical avionic displays played role in 2009 Air France Flight 447 crash "As forward thrust was lost, downward momentum was gathering. Instead of the wings slicing neatly through the air, their increasing angle of attack meant they were in effect damming it. In the next 40 seconds AF447 fell 3,000 feet, losing more and more speed as the angle of attack increased to 40 degrees. The wings were now like bulldozer blades against the sky. Bonin failed to grasp this fact, and though angle of attack readings are sent to onboard computers, there are no displays in modern jets to convey this critical information to the crews. One of the provisional recommendations of the BEA inquiry has been to challenge this absence." via The Telegraph

BOE Technology Group places significant orders for Applied Materials display production equipment "The Applied PiVot PVD and PECVD systems selected by BOE provide a high-performance, cost-effective path to manufacturing stunning high resolution amorphous silicon, metal oxide and LTPS displays. These systems can significantly increase production and achieve the same economies of scale that enabled the cost of LCD TVs to fall by more than 95 percent over the past decade and brought large-area LCD televisions within the reach of billions of consumers around the globe." via Solid State Technology

The Human Body as Touchscreen Replacement "Sean Gustafson, Bernhard Rabe, and Patrick Baudisch from the Hasso Plattner Institute in Germany designed a so-called imaginary interface situated within the palm of the user's hand. This UI is "imaginary" in the sense that there's nothing actually there beyond the naked hand. The photo below shows how an imaginary "mobile phone" could be fitted onto the user's left hand. As each point is touched, a specific mobile function would be activated and announced by a computerized voice." via Nielsen Norman Group

Direct-Dry-Film Optical Bonding: Finding New Applications "OPTICAL BONDING in display products was first used for CRTs and then for flat-panel LCDs around 1980. The technology was confined mostly to low-volume high-performance avionics and military displays for a long time afterward. During the last 6 years, optical bonding has exploded in many commercial and industrial applications, such as iPhones, touch screens, tablets, digital signage, and medical imaging. Optical bonding has grown to a multi-billion (~ $2 billion) industry and is still growing at a fast pace. Liquid bonding has been the most popular optical-bonding technology for many years, but dry-film optical bonding is also gaining in popularity." via The Society for Information Display

Transparent Solar-Cell Screen Charges Phone "Startup Ubiquitous Energy, a spin off from the Massachusetts Institute of Technology, is developing a technology that makes the solar cells themselves transparent by using materials that only absorb infrared and ultraviolet light and let visible light pass through. Researchers at the University of California Los Angeles (UCLA) are taking a similar approach, while researchers at the University of Cambridge are weaving solar cells into organic light emitting diode (OLED) displays, where they can capture light leaked from the edges of the OLED elements as well as from outside the phone." via Discovery News

Society For Information Display Applauds Winners at Display Week 2013 "Display of the Year: Granted to a display with novel and outstanding features such as new physical or chemical effects, or a new addressing method. Gold Award: Sharp and Semiconductor Energy Laboratory (SEL) for Sharp's IGZO LCD (as used in the AQUOS Phone Zeta SH-02E). Silver Award: Shenzhen China Star's 110-inch 4K x 2K 3D TFT-LCD TV" via PRNewswire

Worldwide Microdisplays Market "Microdisplays are small displays that require magnifying optics to use them. These displays are made of a CMOS chip that includes a two dimensional array of transistors. In combination with the liquid crystal material, a cover glass yields a reflective LCD. Microdisplays are generally used in head mounted displays, projectors, view finders, or in other lens view display systems. Continuous and rapid development in display technology has made the way for different types of displays in the commercial market in the past few years." via SBWire

Amazon Acquires Display Maker Liquavista "Liquavista uses a technology called electrowetting to develop color displays for e-readers and portable media players. The first commercially available electrowetting display panels are expected to arrive this year, according to the Digital Reader. ...Electrowetting produces displays with advantages in a couple of key areas—viewability in various lighting conditions and low-power video playback. Amazon, a leading maker of both ereaders and tablets, may be interested in Liquavista's technology for both device categories." via PCMag

New Quantum Dots Make Colors in LCD Even Brighter "In work that appears to tip the scales further for quantum dot-enabled LCDs, researchers at the University of Illinois at Chicago (UIC) have developed a method for doping quantum dots that will give LCDs a color vibrancy not seen before. In research published in the ACS journal Nano Letters ("Cluster-Seeded Synthesis of Doped CdSe:Cu4 Quantum Dots"), the UIC team reveal a method for introducing precisely four copper ions into each and every quantum dot. This doping with copper ions opens up the potential for fine-tuning the optical properties of the quantum dots and producing extraordinarily bright colors." via IEEE Spectrum

Japan Display expands manufacturing "Japan Display President Shuichi Otsuka announced yesterday that the company is boosting capacity of high-definition LCD manufacturing at its plant in Chiba as it has set its target sales this year at 800 billion yen (7.8 billion US dollars), almost double the 450 billion yen it earned last fiscal year. “Our business is now on track,” said Otsuka, who previously was CEO at Elpida Memory Inc. “Our technology is unique, so it won’t be easy for other companies to do the same.” By competitors, Otsuka means companies like Sharp Corp. also from Japan, South Korea’s LG Electronics and Samsung Electronics Co. and Taiwan’s Innolux Corp., also big names in the display-making industry and sharing the market with Japan Display. Japan Display’s share of the global market for small- and mid-sized LCDs was 16.6 percent in 2012, Sharp Corp. held 14.8 percent, followed by LG Display Co.’s 13.5 percent and Innolux’s 10.2 percent." via Japan Daily Press

Displays market loves LED lighting "In conclusion, the benefits of using LED lighting in an automotive environment has several positive implications. First, they never need to be replaced, since their solid state longetivity is in excess of 100K hours – equivalent to 11.5 service years, thereby surpassing the life of the vehicle. This allows automobile manufactures to permanently embed them into “in cabin” backlighting without requiring accessibility for replacement. Styling can also be dramatically altered as LED lighting systems do not require the depth or area as do CCFL bulbs." via Electronics Weekly

Glasses-free 3D display for theaters "It is not surprising that almost every movie is now produced in 3D. An additional incidental benefit is a reduction in illegal in-theater recording of movies. However, there are several reasons why some people are against 3D movies, in particular the discomfort of wearing special glasses. Yet, even though glasses-free 3D display technology has been commercialized for personal devices, such as the Nintendo 3DS, significant limitations must still be overcome for theater-scale projection. For glasses-free display, special optical parts must be installed in front of the screen, which interrupts original images from a projector and is incompatible with conventional theaters. ...To meet this demand, we have developed a glasses-free, front-projection 3D theater display system.2" via SPIE

Application scenarios for interactive OLED data-eyeglasses "The interdisciplinary project FAIR is funded by the Federal Ministry of Education and Research (BMBF). It is dedicated specifically to the support of physical functions by using “hand-free applications in augmented reality“ (FAIR). Within this joint-project demonstrators for innovative human-machine-interactions will be developed. A display – similar to eyeglasses – represents the visionary interface. The control and interaction with the display will be achieved via eye movements. Thus the displayed elements can be seen but provide at the same time the possibility for interaction. This enables the user to start different computer-controlled actions via eye movements. The first steps within FAIR will focus on three special application scenarios: assistance and interaction systems for persons with disabilities, innovative human-machine-interfaces in the field of entertainment as well as information- and augmented-reality-interfaces in industrial maintenance scenarios." via nanowerk

Researchers turn regular LCDs into touchscreen "Doctoral students Ke-yu Chen and Sidhant Gupta work in the Ubiquitous Computing Lab on campus. They came up with the idea for their project, uTouch, while working on a similar project called LightWave that tested how the energy given off by any electronic devices in someone’s house and even by the human body can be manipulated to control an electronic device. The energy, called electromagnetic interference (EMI), is what caused a light bulb to dim and brighten as they moved their hands closer and farther away from the bulb. “We thought that the monitor could have a similar effect,” Chen said. It did. Chen said an LCD monitor radiates EMI, also called noise, to the power line when it is turned on. The EMI increases as the human hand approaches the screen, and uTouch captures the EMI variations and uses them as signals to detect a touch gesture." via The UW Daily

Is touch really the future of the PC? "Right now the best touch pads have an accuracy of 1mm the best touch screens have an accuracy of 7mm. Right off the bat we can see that a touch screen is 7-times less accurate than a touch pad. But there is more to it. When you use a touch pad your eyes are on the object you want to manipulate on the screen while your finger is on the pad. When you use a touch screen your finger is on the screen often blocking the item you want to manipulate. Now consider that the average finger is about 10mm across. You are now blocking the area you want to work on with your finger, which is larger than the sensor in tour touch screen." via Decrypted Tech

Scientists Discovered a New Less Expensive Technique of Creating 3D Images "Scientists at University of Glasgow's School of Physics and Astronomy discovered a new less expensive technique of creating 3D images. They created a system which makes use of the detectors that have single pixel for sensing the light instead of various pixels used in imaging sensors found in digital cameras. The detectors have the capability of judging the frequencies beyond visible light, which in turn would help in various new applications for 3D imaging in geography and medicine. The scientists explained that the single pixel detectors will cost just a few pounds in comparison to present systems which amount to thousands of pounds. " via Jagran Josh

Say Goodbye to the Sharp that We Knew "If we look at the difference between consolidated LCD sales and gross LCD sales before eliminating internal transfers, we see that only 50% to 60% of sales were external transactions in 2008–2012. The portion of external sales increased in FY2013 but the LCD assets in Sakai were removed from consolidation as part of Sharp’s effort to lighten its balance sheet in September of 2012. That means sales from Sakai’s Gen-10 lines no longer contribute to operating results. The problem with that is Sharp’s own capacity becomes only 3% of the industry and that share is declining. Sharp is already smaller than China Star (CSOT) on a consolidated business basis. Thus, Sharp has few alternatives to becoming more of a merchant supplier to other brands, like Samsung." via Display Central

Europe honours LCD screen pioneer Martin Schadt "In 1970 the Swiss physicist achieved a breakthrough that would pave the way for LCD read-outs at first on calculators, watches and alarm clocks, and then flat-panel TVs, laptops and smartphones. But one year later his employer, Roche, thought the feat was a mismatch with its other pharmaceutical-focused efforts and canned the project. Thankfully, the decision proved short-lived and Dr Schadt helped the firm become a major supplier to the screen-making industry, as well as making further contributions to the technology's evolution. His admirers know him as the "father of the pixel", and this week the European Patent Office gave him its lifetime achievement award, noting that sales of devices featuring LCD panels totalled $120bn (£80bn) in 2012." via BBC News

Use of quantum dots with LCD screens in consumer devices edging closer to reality "Quantum dots are very small bits of semiconducting nano-crystals—they're useful because they can be confined in three spatial dimensions allowing for very tight control of emitted light at precise wavelengths. Shining a light through them produces exceptionally pure colors—applying trillions of them to a thin film allows for the display of color richness never before seen with LCD devices. Researchers have been raving about the benefits of the technology for several years while manufactures have been promising that devices with the technology would soon become available to consumers. It appears that such promises are finally about to come to fruition." via Phys.org

Apple going back to Samsung as LCD panel supplier "The industry believes that one of the reasons Apple has decided to come back to Samsung Display is because of its ability to get its hands on thin glass. Thin glass is a major component used in LCD displays that can be found in mobile devices—Apple uses them in its iPhones and iPads." via iDownloadBlog

Europe's largest liquid crystal display factory opened in Ventspils, Latvia "In its new plant in Ventspils Ltd. "EUROLCDS” will produce different types of passive liquid crystal display technology based products. The goal of the company is the global market (Europe and the USA), but primarily the European cluster of LCD products. Liquid crystal display materials will be supplied mainly from China and Japan. One of the largest business segments of the factory will be production of glass that automatically darkens when exposed to bright light for welding masks. Road signs and information display products that use EASL Polydisplay technology will also be produced. At present, the company employs 20 employees, but with the business growing, the number of employees is expected to increase up to 50; in the future there might be 50 more employees employed in distribution and administrative proceedings." via Ventspils.lv

Transparent graphene-based display could enable contact lens computers "The researchers were able to build miniature inorganic LEDs by connecting the graphene sheets together with silver nanowires into a hybrid structure. The flexible silver nanowires enabled the hybrid strucuture to maintain its high conductivity even when bent. The most important factor for using the hybrid graphene in a contact lens-based computer is its high transparency. Other transparent materials like indium tine oxide (ITO) become much less conductive when bent. When the hybrid LEDs were embedded into a regular soft contact and tested in a rabbit no ill effects were observed." via ExtremeTech

Government aid helped make Sharp's IGZO crystals a reality "To develop IGZO, Hosono received research funding from the Japan Science and Technology Agency (JST), an independent administrative agency affiliated with the science ministry. The agency provided 1.8 billion yen ($18 million) of funding for a five-year period beginning in 1999. Of that, around 100 million yen was used for basic research on IGZO. IGZO is dozens of times more conductive than silicon. It can make smaller TFTs and give high-definition quality to liquid crystals." via The Asahi Shimbun

The Future of 3D TV and Why ESPN Dropped Its Pioneering 3D Channel ""3D does cause people to switch off in its present form,” admitted Andy Quested, BBC’s head of 3D and HD. “About 20 percent of people find sports matches in 3D simply too long. Twenty-five percent of people are apathetic toward 3D viewing no matter the content. Another 10 percent can’t see 3D because of visual impairments, but arguably up to half the audience for 3D content is put off by having to wear glasses." Dolby is among the stakeholders arguing that glasses simply won’t work in the home." via The Hollywood Reporter

Innolux sales drop after ceasing touch display operations "In a statement issued on Friday, Innolux reported consolidated sales of NT$37.47 billion (US$1.25 billion) last month, down 8.4 percent from a month earlier and also down 5.2 percent from a year earlier. At an investor conference on May 9, Innolux said the termination of its touch display enhancement technology operations would cut its sales by about NT$5 billion during April and last month, but its gross margin would improve accordingly." via Taipei Times

Hon Hai Annoints Display Research Center In Japan "Hon Hai Precision Industry announced that it has established a research and development center in Japan to focus on display screens and touch panels. As a part of its diversification strategy, Hon Hai is reportedly expanding its businesses outside the OEM sector. The company has continued to invest in the display screen sector; in 2012, Hon Hai acquired a 38% stake in Sharp's Sakai TV panel factory." via China Tech News

New tactile display sends information through skin instead of eyes "Your sense of touch could be the next frontier in relaying valuable contextual information if new research currently being conducted at MIT proves successful. Researchers believe it may be possible to design wearable arrays of GPS-enabled vibration motors that provide simple navigational cues or detailed data through a kind of tactile Morse code. This could lead to non-visual haptic display technology — why not check your email without even opening your eyes?" via ExtremeTech

New Technology Creates Unbreakable Smartphone Display "The plastic substrate created by Professor Yoon and his research team have greatly enhanced needed properties of heat resistance, transparency, flexibility, inner chemical capability, and tensile strength. Although the material retains flexibility as a native advantage of plastic film, its tensile strength is three times greater than that of normal glass, which is a degree similar to tempered glass. In addition, Professor Yoon’s substrate is as colorless and transparent as glass and resists heat up to 450℃, while its thermal expansivity is only 10% to 20% of existing plastics." via PCB 007

How supersensitive screens get touch-y "Have you seen a diagram of a mobile phone display? It's a lot more than the cover glass you're worried about shattering when you drop your phone. There are layers that stack up to form the whole package, from the coated cover glass on top through filters, substrate glass, and screen material, like the LCD or OLED sheaves that actually turn pixels on and off to create the picture you see on the screen." via CNET

A Pleasure To Touch: Advanced Human Machine Interface Touchscreens For Vending "Engineers need to consider three key factors when looking to embed touch control into vending machines. 1. The specified touchscreen solution must be durable, as these pieces of equipment are designed for 24/7 public use. Furthermore, some venders may be deployed in a variety of environments, including outdoors, where they will be subjected to wind, moisture and extreme temperatures. As the machines may be located in lightly supervised areas, the chosen touchscreen should be resistant to deliberate harm from vandalism, in addition to accidental scratches from users' watches and jewelry." via Vending Times

Wearable Computing Pioneer Says Google Glass Offers “Killer Existence” " [Another] thing is that we’re going to see these interfaces that augment the user’s eyes, ears, and mind in such a way that it actually helps with their daily life instead of distracts them. Suppose you’re playing a video game or watching TV. Having something that actually shows you the TV guide or a second screen while you’re doing other things is really powerful." via MIT Technology Review

Developing 3D gesture-based car dashboards "One common aspect of the systems now emerging is that the touch screen head unit represents the nexus of an ever-growing diversity of input signals such as television and DVD, live video and graphics from advanced driver assistance systems, status information from various vehicle sensors, Bluetooth communications, GPS and mapping, and Internet content such as traffic updates, news feeds and social media notifications. User interface design is critical if drivers are to gain the maximum benefit from interacting with the system without suffering distractions or information overload. Considerations for designers extend beyond the layout and menu structure to encompass multiple ways of interacting with the system; touch, gesture and voice control will all be necessary, in addition to control using buttons on the console and steering wheel." via ElectronicsWeekly

Here's the Real Reason Why Virtual Reality Doesn't Work Yet "So, vision and self-motion will spark a little bit of place cell activity, but balance and other sensory cues are what's fully required to properly encode a rat’s — and likely a human's — position. Moreover, the researchers speculate that other cues — like smell, sound, and textures — are what's needed to help the rats properly self-locate themselves. But looking at the scans, the researchers realized that the only spatial encoding that was being done in VR was distance. It’s clear from the study, therefore, that a variety of sensory clues must interact and compete in the brain for us to construct a robust cognitive map." via i09

A liquid crystal force to reckon with "A need for fast, solution-based processing of organic electronic devices has sparked increased interest in ‘discotic’ or disc-shaped liquid crystals. These molecules, which contain a flat aromatic core surrounded by hydrocarbon side chains, can spontaneously pile into column-like structures that could be ideal for one-way charge transport. Research led by Takashi Kajitani and Takanori Fukushima from the RIKEN Advanced Science Institute has now revealed a way to turn individual discotic columns into liquid crystal films with unprecedented hierarchical order in two dimensions ("Amphiphilic Design of a Discotic Liquid-Crystalline Molecule for Dipole Manipulation: Hierarchical Columnar Assemblies with a 2D Superlattice Structure").via Nanowerk

'Next' iPhone display production set to begin "A Japan-based report indicates that production of at least one key component for the next iPhone will begin next month. Sharp will begin volume production in June of the display "panel" for the "next" iPhone model at its Kameyama plant in Mie prefecture, according to a report in Nikkan Kogyo Shimbun, a major Japanese industrial newspaper." via CNET

LG OLED Display: 'Unbreakable' Screen in Works for Apple and Google Phones "LG is shifting away from an unprofitable LCD business into OLEDs (organix light-emitting diodes), according to the Korea Times. "LG Display will produce an 'unbreakable OLED display' -- the first phase of flexible displays -- at our AP2 line of the 4.5th-generation plant in Paju, Gyeonggi Province. The move was aimed at taking a lead over rivals in the race for next-generation displays," Frank Lee, a spokesperson for LG said." via Latinos Post

Amazon's rumoured smartphone with 3D display is an awful idea "The first problem for Operation Hologram is there's no way it won't look completely cheesy. If they couldn't make Tupac look good at Coachella, there's no way in hell they'll make him look good on your phone. Doubt our word? Take a look at the glasses-free 3D screen on the Nintendo 3DS. It's the worst reading environment ever after reading in total darkness. If you're into headaches, fuzzy images, and being let down by technology, you're going to love a smartphone that pushes 3D to your already display-weary eyes." via Wired

Bluescape, the Touchscreen That Covers a Wall "According to The Wall Street Journal, Amazon is working on a retina-tracking phone that produces 3D images. Those images would float above the display, allowing you to relive your Star Wars fantasy of saving Princess Leia. ...The global design director for office-furniture maker Haworth, in partnership with interactive display company Obscura Digital, has created a touchscreen that covers a conference-room wall. Like a supersize version of CNN’s (TWX) Magic Wall, Bluescape displays a unified image across 15 linked 55-inch flat-screen monitors, each equipped with 32 specialized sensors to read users’ hand movements. ..The big hurdle for Haworth will be getting the wall screen’s costs down. A decade of efforts by other companies to market an “iWall” have failed because of high prices, says Roger Kay, president of market researcher Endpoint Technologies Associates, who has not seen Haworth’s product. He cited Hewlett-Packard’s (HPQ) video collaboration and networking system Halo, sold to Polycom (PLCM) in 2011, as a similar tool hamstrung by cost. But “I love the technology,” Kay says of wall-screen designs, adding that they’re the only devices since the iPhone “that made me feel like there was a quantum leap forward.”" via Bloomberg Businessweek

Korea launches touch screen industry forum to help domestic manufacturers grow worldwide "The Korean government has established a forum for touch screen manufacturers in the country, aimed at encouraging cooperation and boosting their global businesses. The move is part of the country’s wider goal to become the world’s second larger touch screen supplier by 2020. The organization was launched by the Ministry of Trade, Industry and Energy today, as the Yonhap News Agency reports. Initial members include large firms like Samsung Display — a business owned by Samsung — and LG Display, in addition to some 120 small and medium touch screen manufacturers." via The Next Web

Inside the factory where Vertu assembles smartphones by hand "Vertu is one of the pioneers of using sapphire to cover its displays, a material which can only be cut with diamond tipped tools. While the screens are prepared offsite, Vertu bonds the sapphire glass to the display at its factory following 48 hours of polishing, a process unique in the industry. They’re bonded in a class 7 clean room, where the staff are clothed in hooded protective gear and the air is extracted through a system built into the windows. If you’re wondering just how clean the room is, class 7 is one step down from being suitable for surgery." via Digital Trends

Revolutionary display technology can lift the ban on digital billboards "Miortech introduces color displays that reflect sunlight, just like paper, with environmental benefits such as low power consumption and reduced light pollution overcoming the disadvantages of LED billboards. Miortech established Etulipa as a subsidiary to bring its electrowetting display technology (EWD) into the digital signage space. CEO Hans Feil states: "We can now demonstrate full color reflective displays with the same approach as in digital printing: the so-called CMY-technology. The positive feedback on our demos, which performed under different light conditions including bright sunlight, pointed us into the direction of the digital billboard applications. We found that advertisers and billboard owners are extremely keen to enable more digital boards. This technology allows for instantaneous creative updates and the ability to respond in real-time to current events and market conditions". The next step is to build a demo-digital billboard to prove our claims to advertisers and billboard owners." via EMSNow

Diamond Pixels: Galaxy S4’s unique subpixel arrangement gets a close up "This is still a PenTile arrangement – there are twice as many green subpixels as blue and red ones. However, at this resolution and pixel density, the drawbacks of PenTile arrangements are very hard to notice. For a primer on the difference between PenTile and the “regular” RGB displays, check out our Galaxy S3 vs Galaxy Note 2 comparison. According to Soneira, Samsung dubbed this novel subpixel arrangement Diamond Pixel, which is a bit misleading, considering that the subpixels (the “dots” of color that make up one pixel) are the ones that are actually diamond-shaped. Samsung probably wanted to distance this new layout from PenTile, which has often been the target of critics due to the “fuzziness” it shows around text and other fine graphics." via Android Authority

MIT tech turns any surface into a user interface "The interface-everywhere zeitgeist highlights the increasingly schizophrenic relationship between display and viewer: do we want greater usability and convenience, or do we want greater resolution and picture fidelity? As relatively low-fi displays like e-ink gain traction in everyday life, the role of the monitor will look increasingly like that of the television. Why consume Facebook the same way as Game of Thrones — does a wall post require such detail? And if a low-res display clamped against your temple can put a friend’s latest tweet next to their face as you speak to them, we might begin to wonder why we ever believed that a huge desktop screen was a good way to handle our increasingly endless digital chores in the first place." via ExtremeTech

Garmin's Glass Cockpit "Information is displayed on the center touchscreen, as well as between the speedometer and tach. If one display goes down, the other will still function, reflecting Garmin's aviation-oriented redundancy mentality. A future head-up display is being designed into K2, as well. Interestingly, the touchscreen doesn't incorporate haptic feedback. Garmin argues it's not particularly effective and said the screens suffer unacceptable response lags. There will also be some analog technology set below the display. "In K2, we didn't put everything into the touch panel," product manager Kip Dondlinger says. "I'm still a strong believer in volume and temperature knobs and some preset buttons."" via Autoweek

Why Corning Isn't Scared of Sapphire As Disruptive Threat To Gorilla Glass "It turns out that Corning isn't scared of sapphire. The glass specialist has conducted a number of in-house tests to see how sapphire stacks up with its latest Gorilla Glass 3, with its own product coming out on top. The study involves placing two devices -- one covered in sapphire and another sporting Gorilla Glass -- into a spinning container full of everyday objects. After a 45-minute twirl, both materials are subjected to a ring-on-ring strength test that applies pressure. Corning says that Gorilla Glass withstands more than 2.5 times as much force." via The Motley Fool

Finger-free phones, full body gesturing, and our “touchscreen” future "Understatement of the century: touchscreen technology evolved at a rapid pace in the past decade. In the days of Y2K, Palm Pilots were a big deal. Five years ago? The iPhone debuted and the corresponding touchscreen explosion hasn't slowed up since. Today we're at a point where we think we understand how all the innovations in touch technology can fit into our future. But based on these last few years, good luck. Did anyone see the tablet-craze coming? The locomotive of technological innovation has yet to be derailed, but it’s come to a point where we must find particular uses and integrations for all of these advancements. Looking at how companies like Microsoft and Samsung are approaching the future of touchscreen technology may be the surest clues we can get. " via Ars Technica

Flexible smartphone curls up when it gets a call "The MorePhone is a very acrobatic smartphone. It's made with a flexible display and shape memory alloy wires. When a call comes in, it activates the wires and causes the whole phone to curl up. It's an unmistakeable visual cue that you've got someone on the line. The curling smartphone was developed by researchers at Queen's University Human Media Lab in Canada. The thin electrophoretic display that makes the movement possible was manufactured by Plastic Logic, a company specializing in plastic electronics. The alloy wires can trigger the phone to curl up at all corners, or to curl back individual corners to indicate different events, like an incoming text message or e-mail." via CNET

Frog Predicts: Flexible Displays Will Soon Change The World "As screens are reshaped, so will our experience of information. Rolston likens our tiny screens to “discrete pods of data,” whereas curved displays will break many of the natural barriers imposed by bezels. Imagine a recipe that doesn’t just appear on your wall or countertop, but can actually follow you around your kitchen, snaking its way into the nooks around faucets and refrigerator handles and presenting the pertinent information right where you need it (how many cups of water was that again? What should I be grabbing from the fridge?)." via Fast Co.DESIGN

Why Samsung and Intel bet big on a startup that searches every word you say "But why are three very different kinds of companies — an electronics manufacturer, chip maker, and telecom giant — all so interested in this little startup? For Samsung, the maker of the Siri clone S Voice and a company with a reputation for stuffing as many disparate software features into its gadgets as it possibly can, the answer is obvious. "Samsung imagines a world not too long from now where there is a flat-screen in every room. You might have a phone or tablet they built on you, but Samsung will also have a screen in your wall or on your refrigerator," says Tuttle. "They are interested in technology that can use voice commands as an input, that can listen to a conversation and provide answers without needing to be asked."" via The Verge

The Wacky World of OLEDs "If we ever get large OLEDs right — that is, if we learn how to print the front plane; use IGZO or graphene or carbon nanotubes for the backplane; develop flexible and reliable moisture and oxygen barriers; and fabricate reliable displays via roll-to-roll processing with high manufacturing yield — there will no longer be much reason to bother with either LCDs or plasma display panels. That goal continues to inspire investment, but it continues to be very, very elusive." via Display Central

The future of 'green' screens in digital signage "With LED backlighting, for example, the backlight stays true longer and degrades in performance more slowly than a CCFL backlight, Karnani said. "So it's not that it's just an environmental initiative, there's also an improvement to the actual display from the customer's standpoint, so I would say that ends up being really a win-win," she said. "Reduced total cost of ownership absolutely goes right to the ROI for the investment; it is not only environmentally friendly, it's a better product and you're going to save money."" via Digital Signage Today

3D Computer Vision Short Course at Display Week "The course explores key elements of vision including visual perception and the human visual system (seeing vs. perceiving). Bhowmik then delves into Image formation and capture including both 2D and 3D techniques that look at four cases including single and stereo view plus 3D imaging with structured light and time of flight. He next turns to the algorithms dealing with inference and recognition (the math) and leading-edge techniques that include the importance of edge detection and why. Bhowmik shows the calculus that helps identify the edge by displaying the image as an “image intensity function” and characterizing (finding) the edge as the place of rapid change along the horizontal scan line (first derivative) citing the work of John Carry at the MIT A.I. Lab, calling it “…the most widely used edge detector in computer vision today.”" via Display Central

An elastic touchscreen into which you can literally sink your fingers "The stretchable touchscreen, dubbed Obake, was created by Dhairya Dand and Rob Hemsley, both of MIT’s Media Lab. The touchscreen basically amounts to an interactive display on top of an elastic surface. When you poke or pull at the display, depth cameras measure your movements and tell linear actuators to manipulate the elastic surface accordingly. So, if you make a pinch-and-pull motion, the depth cameras will measure it, then the linear actuators will make elastic stretch and protrude in such a way as if you’re pulling it. The surface doesn’t just create little mountains of stretched elastic; it can also create resistance if you, for example, push inward rather than pull outward." via ExtremeTech

The American Display Company That Samsung Relies On For Success "When the S4 launches this month it will have a new generation of clarity in the display, one that iPhone lovers might envy. It will be thinner. And the battery life will be extended by about 20%, even with the high definition screen. It’s about to become a better phone. The reason for this is US technology. At least that is one important reason. Technology that gives the Galaxy S4 a better screen but also longer battery life and the thinner form factor. Samsung’s Galaxy S4 relies on materials and patents from New Jersey-based Universal Display Corporation. Without Universal there would be no efficient, thin, beautiful OLED display for the S4. But Universal’s relationship with Samsung goes back through the whole Galaxy line. And it stretches far into the future." via Forbes

High-tech specs: Electronic eyeglasses offer wearers more control ""It totally removes the corridor of traditional progressive lenses," he said. "So it makes your reading seem like you're reading through single vision lenses. [It's the] same with the computer use, so instead of relying on a little corridor and adjusting your head, you can use the whole lens to see distance, intermediate and up close, so it really enhances the comfort." ...He compared the technology of the touch sensor to that of a smart phone. The eyeglasses have "a microchip, composite lenses with a thin transparent LCD-like layer, miniature rechargeable batteries and a micro-machine accelerometer to detect tilt," according to a press release. "The microchip, micro-accelerometer and miniature batteries are hidden inside the [eyeglass frame]. The transparent liquid crystal layer in each lens is able to electronically activate the reading portion when the wearer needs it."" via The Altoona Mirror

World's first smartphone for the blind "The smartphone uses Shape Memory Alloy technology, based on the concept that metals remember their original shapes, i.e. expand and contract to its original shape after use. The phone's 'screen' has a grid of pins, which move up and down as per requirement. The grid has a Braille display, where pins come up to represent a character or letter. This screen will be capable of elevating and depressing the contents to form patterns in Braille." via The Times of India

This Bobbing Display Lets You Read While Running On A Treadmill "Instead of simply enlarging the text to make it easier to read or relying on oversized monitors, ReadingMate allows a treadmill user to read normal-size text on a small monitor mounted in front of the machine. The system relies on infrared lights embedded in special goggles that are tracked by an infrared camera positioned in front of the runner. As the user’s head moves vertically, the system moves the text accordingly. ...In addition to letting treadmill users catch up on some reading while burning some calories, the researchers say ReadingMate could also find aviation, construction and transportation applications. Not to allow drivers and pilots to enjoy a good book while on the job, but to stabilize information displayed on screen while experiencing heavy shaking or turbulence." via Gizmag

A Simple Way to Turn Any LCD into a Touch Screen "A group of researchers from the University of Washington’s Ubiquitous Computing Lab developed a method called uTouch that uses a simple sensor and software to turn an ordinary LCD into a touch screen display. The system takes advantage of the low levels of electromagnetic interference produced by many consumer electronics, harnessing it to do things like control video playback with pokes and motions on an otherwise noninteractive screen. “All these devices around you have all these signals coming out of them, and we ignore them because we think they’re noise,” says Sidhant Gupta, a PhD candidate at the University of Washington’s Ubiquitous Computing Lab and one of the co-authors of the paper." via MIT Technology Review

Are touchscreens right for all equipment? "“With touch, you lose tactile feedback. With traditional controls a person using the instrument can continue to use the equipment without having to stare at it,” says Siegel. This is true of much research equipment, which requires simultaneous fine-tuning of several pieces of equipment at once. Sometimes functions available in one section of an application on a touchscreen are difficult to access from another section. This could be one reason TI has not seen a widespread adoption of touchscreen technology in the scientific research space. Siegel speculates that the consumer market usually sets the trend, and popular capacitive touchscreens are general overkill for research instruments." via R&D Magazine

U.S. Seeks Voluntary Limits On Car Touchscreens "The new guidelines limit simple tasks to two seconds. They also restrict the time allowed for complex tasks to 12 seconds, but do not limit the number of times a driver can touch a screen. The decision on whether a screen would freeze or shut down after 12 seconds would be left to automakers based on their own research, NHTSA said. The auto industry’s current guidelines, which are a decade old, allow drivers to read text and perform other more complex tasks while cars are moving at less than 5 mph, Strickland said. Systems now are designed so multiple-step tasks take 10 or fewer screen touches for a total of 20 seconds with a driver’s eyes off the road. But the devices won’t turn off or stop a driver from doing something that takes longer than 20 seconds." via CBS DFW

Prototype could revive glasses-free 3D displays "Dolby says they have now developed a system that encodes a 3D image stream and can decode it in real time to produce 3D without the need for glasses on "any 3D TV, tablet, laptop or smartphone" with sufficient resolution. The design requires adding a sheet of plastic with undulations that deflect light at 26 different angles simultaneously, offering effective 3D views from a wide range of angles. Because resolution is lost as an image is split and sent in different directions, the underlying display must be four times the resolution of HD television. Such displays are expensive, but they are becoming available, so 3D may yet have a future." via New Scientist

Why Don't We Have Holodecks? "Researchers at the University of Illinois at Chicago recently created Cave2, the highest-resolution immersive panel display in existence. The cave is made up of 72 3D LCD panels arranged in a 320-degree shape. A special pair of glasses with tracking dots on them helps the computer know in which direction you're looking so it can adjust the images to fit your perspective. You can also use a wand, covered with sensors, to interact with the 3D objects around you. For now, the system is used for high-resolution medical-image viewing. It's cool but probably won't be in your living room anytime soon. What about recreational holodecks? Nathan Burba, director of Project Holodeck (which is exactly what it sounds like), told PM that cost has been a big issue until recently. "I would say that the technology has obviously been limited," he says. "The display technology has been locked away in military research, and there's a lack of innovation there because of the stringent requirements put on researchers."via Popular Mechanics

Google Glass is finally here: Tech specs released, first units shipped "According to the spec sheet, Google Glass will offer one full day of battery life for normal usage, but features like Hangouts and video recording will expend the battery faster. Google recommends recharging the kit with with the Micro USB cable and charger it supplies with Glass. The display resolution is the "equivalent of a 25-inch high definition screen from eight feet away", but Google is being no more specific than that. " via ZDNet

LG Rolling Out Curved OLED TVs in South Korean Market "Why curved? The idea is to offer to an IMAX-like experience in the home. A curved display also eliminates the problem of screen-edge visual distortion and loss of detail since the entire surface is equidistant from the viewer's eyes, LG says. The curved TV itself is just 4.3 millimeters (0.17 inches) thin and weighs 37.48 pounds. It uses proprietary WRGB technology and a four-color pixel system that features a white-sub pixel in addition to red, blue, and green." via HotHardware

Japan Display turns to smaller smartphone makers "Japan Display, the world's No.1 maker of small to mid-size panels, may increase sales to as much as 800 billion yen ($8.10 billion) for the fiscal year ending March 2014 from slightly below 500 billion yen a year earlier, said Shuichi Otsuka, CEO of the unlisted firm. The company, formed out of a merger of the small panel divisions of Sony Corp, Hitachi Ltd and Toshiba Corp last April, does not publicly identify its clients but is widely known as a key Apple supplier. Apple undershot Wall Street's sales forecast for the third straight quarter in the three months ended December after iPhone sales missed expectations." via Yahoo! News

Future of Computer Human Interaction on display at Paris conference "The future of computing comes to Paris this week with the annual Computer Human Interaction (CHI) conference, which showcases new approaches to the way users connect with electronics. ...One of the big draws at the conference is the “interactivity” section, which is like a mini trade show of futuristic prototypes that attendees can try out for themselves. Gone are the days of just keyboards and mice. “We’re seeing things that go much further into the future,” Baudisch said." via PCWorld

How today’s touchscreen tech put the world at our fingertips "Because it's so different from mouse-and-keyboard-driven and stylus-driven software, touch-driven software has also transformed the hardware it runs on. Most smartphones include just a few physical buttons: power, volume, a mute switch, and the home button. Using a touchscreen as the primary input obviated the need for things like a hardware number pad or keyboard, since the screen could dynamically become whatever it needed to be. Software keyboards have become even more context-sensitive over time, adding things like a ".com" button when typing in a URL field." via Ars Technica

Aggressively combat noise in capacitive touch applications "Today, thin is in. The push to make aggressively thin form factors for touchscreen devices, especially mobile phones, creates a two-fold problem: more noise coupled into the sensor from the display and a higher parasitic capacitance of the sensor. Displays generate noise that is much lower amplitude when compared with charger noise, but they can have a huge impact on touch performance due to their close proximity to the touch sensor. While AMOLED displays are very quiet (but more expensive than LCDs), the majority of the market today is still the noisier ACVCOM and DCVCOM-type LCD displays. It is the VCOM layer, the common electrode, of these displays that is the source of their noise." via EDN

Fujitsu Laboratories New Touch-based Interface Marries Analog & Digital "Transform boring, poorly stapled business plans, press releases, marketing materials and other old fashioned paper artifacts to life using Fujitsu Laboratories’ touchscreen interface that can animate and bring a whole new dimension to real world objects. ...This amazing touchscreen interface is also non-biased and can adjust color and brightness, and skin color accordingly so that it isn’t influenced by external or environment circumstances. In addition, if you don’t want to operate the device by touch alone, you can also manipulate the sensors with gesture controls — you can explore three dimensional objects with the simple movement of your fist to get a full 360-degree view." via Gadizmo

Samsung Demos a Tablet Controlled by Your Brain "The concept of a dry EEG is not new, and it can carry the drawback of lower signal quality, but Jafari says his group is improving the system’s processing of brain signals. Ultimately, if reliable EEG contacts were convenient to use and slimmed down, a brain-controlled device could look like “a cap that people wear all day long,” says Jafari." via MIT Technology Review

Advances in capacitive touchscreen for mobiles "First, it is critical for designers to understand the underlying construction of a touchscreen system to be able to understand how technology changes are remaking this segment. The key components in a touch system include the coverlens, sensor, LCD, and PCB. The coverlens is the outward facing component of the product. This is where the consumer interacts with the screen. In some products, this coverlens could simply be a protective cover to prevent scratching and damage, or it can actually be part of the touch sensing system itself." via EET Asia

'Interactive Fish Tank' turns water into a capacitive touchscreen "Once it makes contact with the surface, Donoso explains, a finger "acts in the same way as touching a button on an iPhone or any other touch screen." Indeed, in substituting glass for water, Donoso and Moore present a different, and perhaps more accessible way to understand how capacitive touch works on traditional displays. The underlying principle is the same: a user's touch elicits some change in the surface at the point of contact, and the software reacts accordingly. Whereas smartphone displays gauge this change in terms of electric charge, "Fish Tank" measures it in ripples." via The Verge

Discomfort and fatigue from stereo 3D displays "In stereoscopic displays, images have varying binocular disparity thereby stimulating changes in vergence as happens in natural viewing. But the accommodative distance remains fixed at the display distance, so the natural correlation between vergence and accommodative distance is disrupted, leading to the so-called vergence–accommodation conflict. The conflict causes several problems. First, differing disparity and focus information cause perceptual distortions. Second, viewers experience difficulties in simultaneously fusing and focusing a stimulus. Finally, attempting to adjust vergence and accommodation separately causes visual discomfort and fatigue in viewers." via SPIE

Shapeshifters: phones of the future could morph on demand "The six working prototypes, known as "Morphees," are thin, electronic displays capable of automatically changing shape to perform certain functions. Researchers say that if brought to market, the devices could usher in a new era in mobile computing, breaking down the physical barriers that have traditionally defined smartphones, tablets, and gaming consoles." via The Verge
