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

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

Display industry prepares for SID 2014 "The 51st SID International Symposium, Seminar and Exhibition, or Display Week 2014, will take place June 1-6, 2014 at the San Diego Convention Center in San Diego, Calif. Display Week is the premier international gathering of scientists, engineers, manufacturers and users in the field of electronic information displays.

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. In collaboration with Cisco, this cockpit concept securely connects all aspects of the vehicle to the user profile and cloud services. It uses a secure data pipe that actively switches methods (modem, phone tethering, WiFi®), while maintaining a seamless connection to the cloud. This makes the cockpit adaptable through personalization, off board computing and intelligent vehicle module updates - giving the user and auto manufacturers intelligence about user interactions and preferences to improve the HMI experience.

HMI trends in industrial touch screens "Glass touch displays are also setting a new design trend which optically excels with its smooth and seamless glass surfaces. At the same time though this is where the challenge begins: Where robust designs are concerned, the glass panel cannot just be stuck on the back with an assembly kit, like, for example, is the case with ceramic cooking areas, in order to create a shock- and vibration-proof hold. Especially not when the opening of the housing on the machine or equipment has to offer comprehensive protection against dust and spray water." via Electronics News

Apple patent filing points directly to 'iWatch' concept with flexible touchscreen display "In another embodiment, the invention calls for a more robust design in which the flexible display is mounted directly to the bracelet and "framed" by a thicker, more comfortable fabric covering. Switches and critical electronics should also be resistant to fatigue, the patent notes, as the bracelet switches from a convex shape to a concave configuration depending on whether it is being worn by the user. When in its "curled state," or otherwise attached to a user's arm, the bracelet can take on the form of an uninterrupted screen. On-board sensors, like gyroscopes and accelerometers, would aid in orienting the screen's information toward the user." via Apple Insider

Polytron Unveils Transparent Smartphone Display Prototype "Taiwan-based Polytron Technologies are apparently already experimenting with a glass like smartphone with a multi-touch display.The prtotype device called Switchable glass is a conductive OLED display (organic light-emitting diode) makes use of liquid crystal molecules, that emit light in response to electric current. When the device is switched off the molecules take the form of a white cloudy like substance, which transforms the device to appear like glass." via Gizbot

Apple CEO blasts OLEDs as inferior tech – independent research shows he has a point "At a Goldman Sachs investor conference today, the Apple CEO dismissed the idea that the display technology is something Apple should adopt, noting “If you ever buy anything online and really want to know what he color is, as many people do, you should really think twice before you depend on the color from a OLED display.” Cook, asked if Apple would consider creating devices with larger displays, said that size and specifications are things companies focus on when they can’t “create an amazing experience.” That’s obviously a shot across Samsung’s bow, but it’s an arguably true evaluation of both the PC business and smartphone manufacturing." via ExtremeTech

Touch panel market projected for 34% growth in 2013 "The financial crisis that started in 2008 left much of the IT industry hobbling worldwide. But only the touch panel market is enjoying a boom. Many new players are pouring into the industry, and those on the sidelines are waiting for the opportune moment to enter. As more players enter the competitive landscape, touch panel prices are falling rapidly. In addition, to gain competitiveness and to differentiate itself in the market has led players to develop and improve structure, technique and process, and seek out new materials." via Solid State Technology

LG Display betting on OLED to the tune of $657 million "Today we learned that LG Display has invested a whopping $657 million in the production of large OLED TV screens, a figure that will enable it to produce 26,000 mother glass sheets a month which are big enough to make six 55-inch screens per sheet. In other words: the company will be capable of churning out 156,000 panels per page turn on your calender. Since LG display is the largest flat-panel producer in the world, and since LG Electronics owns a 38 percent stake in it – it stands to reason that LG proper will be buying plenty of the new panels. This is news that should resonate industry-wide." via Digital Trends

Panasonic Says Plasma is still the best TV technology "Unlike LCD TVs which use an array of LEDs to illuminate their pixels, plasma TVs use glass panels containing over two million tiny cells filled with a mixture of inert gases. An electric current passed through these cells excites the gases, causing them to illuminate the pixels across the screen. This method of lighting is traditionally a lot better for motion reproduction, contrast levels and reducing 3D crosstalk than LCD tech. But they do suffer from a lack of brightness and come with bulkier chassis than their LED cousins." via TechRadar

ISSCC 2013: Imagers, MEMS, Medical and Displays "Significant R&D effort is being spent on active 3D imaging time-of-flight (TOF) applications to support requirements from autonomous driving, gaming, and industrial applications, addressing open challenges like background light immunity, higher spatial resolution, and longer distance range. Deep-submicron CMOS single-photon avalanche diodes (SPADs) have been developed by several groups using different technology nodes. They are now capable of meeting the requirements for high resolution, high timing accuracy by employing highly parallel time-to-digital-converters (TDCs) and small pixel pitch with better fill factor. ...This and other related topics will be discussed at length at ISSCC 2013, the foremost global forum for new developments in the integrated-circuit industry. ISSCC, the International Solid-State Circuits Conference, will be held on February 17-21, 2013, at the San Francisco Marriott Marquis Hotel." via Solid State Technology

Three-dimensional dancing bear shows the way to practical holographic display "Three-dimensional holographic displays can provide truly realistic images because they provide all the depth cues required by the human visual system and eliminate visual discomfort. However, the development of a practical holographic display system is limited by the availability of a spatial light modulator (SLM) with a large pixel count and closely spaced pixel element (small pixel pitch). Such a SLM is critical to achieve a large displayed image and a wide viewing angle.1 Over the past five years, we have developed three holographic display systems to combat this problem, each with an increasing degree of sophistication, resolution, and color reproduction quality." via SPIE

Improved Moisture Barriers for Organic Displays and Electronics are Coming "Materials used in OLED or OPV devices degrade rapidly when they contact oxygen or moisture, so they must be sealed tightly. In contrast, inorganic devices such as conventional TFT LCD or TFT-EPD survive the presence of humid air about a thousand times longer. In fact, EPD, such as electrophoretic E Ink displays, need some moisture so its encapsulation is meant to keep water in, rather than out." via Display Central

Key patent analysis on quantum dot displays released "The quantum dot recently emerged as a next-generation display material. Quantum dots, whose diameter is just a few nanometers, are semiconductor crystals. The smaller its particle is, the more short-wavelength light are emitted; the larger its particle is, the more long-wavelength lights get emitted. Considering that there are more advantages with the quantum dots over conventional light sources, it is not surprising that the quantum dot display gains a lot of attention." via Solid State Technology

Sharp develops technology to recycle glass from LCD TVs "Sharp Corp has developed technology for reprocessing the glass from used LCD panels, a discovery seen helping to lower recycling costs for consumers. ...Working with Osaka Prefecture University, Sharp found a method for turning the crushed glass from panels into zeolite via reactions in an alkaline solution. The firm foresees stable demand for the material, which is used as an absorbent to purify water and as a soil treatment, among other purposes. A 40-inch panel would yield roughly 200 yen (US$2.35) worth of zeolite." via Waste Management World

As touch screen market grows, Asia gains advantage on industry ""Demand is growing for thinner, light weight, and lower cost touch panels and devices. In addition, we see strong touch screen growth over the next several years in larger display applications such as convertible/hybrid notebook PCs and all-in-one PCs,” saidJennifer Colegrove, Vice President of Emerging Display Technologies at NPD DisplaySearch. “Over the next few years, in-cell, on-cell, and sensor-on-cover touch technologies will surpass the add-on type projected capacitive touch.” To meet consumer demand, technology companies are adapting to the market simply by adding touch screen abilities. Google, for instance, was rumored to be installing a touch screen in its next Chromebook. Although the conjecture came from a “leaked” video last week, it is inevitable that more laptops will feature touch screen technology." via Digital Journal

Apple's iPhone 5 Integrated Touch Display Technology Comes to Light and it loudly Screams it's Coming to all Macs Eventually "Specifically, rather than employ a separate, overlaid touch sensor panel over an LCD panel, embodiments of the present disclosure may incorporate integrated touch sensor components in-cell within display pixel cells of the LCD or on-cell above the display pixel cells. Among other things, these touch sensor components may include a conductive portion of in-cell black matrix, which also may shield light from one pixel from bleeding into another pixel." via Patently Apple

What do TV screens, bullet-proof vests and soap all have common? "Nematics were discovered in Germany in the late 19th century by virtue of their appearance under polarised light (as shown in the image), but no one realised they were more than a rather beautiful intellectual curiosity for another 50+ years. They are useful in displays because their alignment can be switched on and off by an electric field, so allowing individual pixels in a display to be separately addressed. Getting large areas of such displays to work perfectly with low energy consumption and high contrast are all technological issues; the basic physics (and requisite chemistry of the molecules) has now been known for many years. ...So, in the century and more since liquid crystals were first identified, they have transformed from an esoteric if attractive curiosity to a key class of materials in our everyday world. Things would look very different without them, as a quick appreciation of the screen on which you read this will make you realise." via The Guardian

Haptography and the science of touchscreen texture (interview) "The modeling approach relies on data recorded from dragging a specially sensorized tool across real textured surfaces. The tool measures the induced vibrations as well as the speed and force the person used. From this data I am able to make mathematical models to represent the feel of the surface for reproduction on the tablet. We've coined this method of data recording and modeling as haptography (haptic photography) because it allows a person to record the feel of an interesting interaction in much the same way that traditional photography allows a person to visually record an interesting scene or object." via Display Alliance

Sony's HMZ-T2 Personal 3D Viewer "On the plus side, the dual 720p OLED displays were bright and contrasty, which really works for gaming. ...it’s an impressive piece of technology, and after a few more iterations (and some significant price drops), could possibly become a realistic alternative to a conventional 3D display." via The Verge

Single-Axis Flat Panel Design Offers New Angle On CPV Technology "This is where concentrating photovoltaic — or CPV — technology comes in. Typically, CPV technology collects a large amount of sunlight, “bundles” it through lenses or curved mirrors and directs it onto a small area of solar cells to generate electricity. ...The Industrial Technology Research Institute (ITRI) in Chutung, Taiwan, however, has developed an entirely new type of CPV design that functions much like a LCD display, only in reverse." via Solar Novus Today

World's biggest touchscreen "Made up of 24 55-inch MultiTaction Cell displays the idea is that you'll have an entire bank of the screens measuring some 10m x 3m allowing you to touch and stroke our way through your workload. ...Unlike similar devices, MultiTaction Cells, claim the company, can track multiple concurrent interaction methods including hands, optical markers and real life objects." via Pocket-lint

Tactile Touchscreens: Tech’s Next Big Thing? "“In the technology industry, a lot of products are created because the elements are available, not necessarily because there is a need,” says Paul Krumrich, the president of Spyeglass, a Minneapolis-based integrated design company that produces digital displays and signs. “I think for [tactile] touchscreens to be successful they need to make the process of getting to an end result easier, increase efficiency or enhance an experience. [Designers] need to avoid over-saturating a person with technology if they’re just looking to find something quickly. People will become frustrated if they need to wait for a screen on their phone or a kiosk if to feel like a special material.”" via Business 2 Community

Panel Manufacturers Vow to Reduce Production for Profit "Senior executives of Samsung, LG, AU Optronics Corp. (AUO, NYSE: AUO) all stated during the FPD International China 2012/Beijing Summit that profitability would become their primary management objectives in the future." via MENAFN.com

The evolution of video walls "Video walls in the early 1980s were built by mounting cathode ray tube (CRT) televisions (TVs) in a grid formation. These were typically 711-mm (28-in.) screens, with large gaps between sections. With each display hard-wired to a single content source, display options were limited." via Kenilworth
