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

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. (Video)" via MIT News

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." (Video)" via Fast Company

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

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

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

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

Comparison of Display Polarizer Technologies "The Moxtek® wire grid polarizer technology provides a consistent, highly durable solution to high quality LCoS display technology with a perfect polarization match to the LC imager. Latest improvements in the polarizing beam splitter (PBS) technology enable a 10% improvement in efficiency. This technical article offers a comparison between imaging needs and how Moxtek is improving its products. 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.

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

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

How the industry shift from miniturization to display quality blindsided Motorola "The spectacular success of RAZR in 2005 was a cruel red herring. It convinced Motorola that focusing on making slimmer phones instead of improving display technology and user interface software was the way forward. The RAZR models featured a 30% thinner chassis than rival phones — and a nightmarishly messy, menu-based software system. The demand spike for RAZR models was the indian summer of the miniaturization obsession that dominated the phone industry in 1992-2002. It misled many leading phone vendors to ignore their profound software user experience problems just before Apple entered the phone market and devastated the old guard." via BGR

New 3-D Display Could Let Phones and Tablets Produce Holograms "The HP display uses nanopatterned grooves, which HP researcher David Fattal, who led the work, calls “directional pixels,” to send light off in different directions. This requires no new moving parts, and the patterns are built into an existing display component, the backlight. A conventional LCD uses a sheet of plastic or glass that’s covered in bumps that scatter white light and direct it through the display’s color filters, polarizers, and shutters to the viewer. The new 3-D display builds on optics research demonstrating how the path, color, and other properties of light can be manipulated by passing it through materials patterned at the nanoscale." via MIT Technology Review

Growth slowing for TFT LCD glass substrate capacity ""With TFT LCD business maturing and growth slowing, leading manufacturers have begun to mitigate their business risk by converting production from TFT LCD glass to aluminosilicate glass," according to Tadashi Uno, director of materials and components market research at DisplaySearch. "With Corning Gorilla glass now dominant in the aluminosilicate glass market, it is critical for other TFT glass makers to find ways to jump on the cover glass trend to gain additional market share."" via DigiTimes

Fraunhofer HHI Conducts 3D Surgical Study "Test using the glasses-free display were not top ranked. Surgeons said it was comparable to working with the 2D screen. Dr. Ulrich Leiner, head of the Interactive Media – Human Factors department at HHI, noted that this display is a two-view glasses-free type with eye tracking used to present the stereo images to the surgeon based on their head/eye position. “While the glasses-free technology still requires some fine-tuning, we believe improvements will increase the popularity of 3D systems in operating rooms,” said Leiner. “The study demonstrated that 3D has become an option for surgeons as well. This will revive the discussion among skeptics. And now there is a need for tests in other medical disciplines,” concluded Leiner." via Display Central

Warm 3D images using thermal displays "Stereoscopic or 3D displays—such as stereoscopic LED displays with polarized glasses or multi-layer 3D displays—allow a viewer to perceive the depth of an image to provide a richer viewing experience. Much research has been dedicated to determining how to offer blind people, or individuals without stereoscopic vision, the opportunity to experience this 3D effect. A possible solution is to use the sense of heat: employ three-dimensionally localized heat spots that provide a thermal sensation when an individual walks through the 3D image. Our research aimed to realize thermal and visual aerial signage, a technique that forms a 3D pattern composed of heat and light in the air, without any physical hardware at the position of the sign. These warm 3D images can be used, for example, to display advertisements alongside a footpath or side walk. In addition to seeing these signs, users can feel them when their faces touch the thermal images." via SPIE

LED LCD backlights explained "The so-called "blooming" that plagued early local-dimming LED LCDs has been greatly reduced. With the better TVs, there are few artifacts like these images. Instead, the processing errs on the side of safety, not allowing adjacent LEDs to get too different in brightness, so as not to have issues like you see here. The flip side of that is less "punch" in the image, as bright objects on an otherwise dark background don't appear as bright. " via CNET

LCDs and the lost art of photography "The immediacy of the LCD has changed the craft of photography. It’s made it so much easier to learn quickly, to grow and to take much greater chances and push the envelope much further. ...A little bit of the “magic” of photography -— has left us. There’s nothing quite like seeing a print come to life in the developer tray in the darkroom. Also, a certain type of discipline is instilled in you when you are faced with a 36-exposure roll and the cost associated with it, not to mention the cost of getting it processed and printed. These days I more often that not read 999 on the still camera’s LCD when a large CF Card is in place. Where’s the challenge in that? ...As the world continues to move faster and faster, as processors, resolutions, dynamic ranges, and terabytes keep increasing at an exponential rate, sometimes I think we could all do with a roll of 36 exposures." via Gizmodo

Nintendo Found Guilty of Patent Infringement with Stereo-3D Tech on 3DS "The auto-stereoscopic 3D display used by Nintendo with its 3DS portable video game console relies on pretty simple and well-known method. The S3D display uses a parallax barrier system to display 3D images. This parallax barrier, which has a series of vertical slits, is incorporated into an ordinary LCD to control the path of light reaching the right and left eyes, thus creating a sense of depth. Another name of this technology is called lenticular lenses tech. Since initial parallax barrier-based S3D LCDs had issues with the right reproduction of colors, many companies, including Nintendo, LG, Sharp and others implemented various additional technologies to eliminate the drawback." via Xbit Laboratories

Tech start-up of the week: LCD recycler ALR Innovations "ALR Innovations has pioneered a LCD screen recycling technology that consists of a fully automated machine that processes waste LCDs to remove the potentially hazardous materials they contain. Materials such as the mercury-containing fluorescent tubes and the liquid crystal panel. The machine processes 80 LCDs per hour, which offers the recyclers a fast and efficient process that is compliant with mandatory EU legislation, O’Donoghue said." via siliconrepublic

What If Google Glass Flops? "Thus, it doesn't matter whether Google sells 10 pairs of Glass or 10 million. What matters is that Google's involvement is already popularizing this kind of technology. This can be seen in the plethora of patent filings that have recently been filed by the likes of Apple (AAPL), Microsoft (MSFT), Samsung (SSNLF.PK), Sony (SNE) and others. In short, if Google doesn't get it right, someone else will. In fact, smartphone glasses may not even be the first hit. For example, Microsoft also has its sights set on gaming goggles. This demonstrates that computerized eyewear is ready to cross the chasm." via Seeking Alpha

Taiwan to hold touch panel display exhibition in August "The International Touch Panel and Optical Film Exhibition 2013 (Touch Taiwan 2013), one of the most important exhibitions for the display and touch panel industry in Asia, is scheduled to be held Aug. 28-30 in Taipei, the event organizers said Tuesday. Touch Taiwan 2013, to be held concurrently with the International Display Manufacturing Conference 2013 (IDMC 2013), will mainly showcase touch screens, panels, optical film, related equipment and materials." via Focus Taiwan

Do quantom dot displays pose challenges for OLED? "Quantum dots (QD) or semiconductor nanocrystals are a form of light emitting technology and consist of nano-scale crystals that can provide an alternative for applications such as display technology. This display technology differs from CRTs and LCDs, but it is similar to OLED displays, in that light is supplied on demand, which enables new, more efficient displays and allows for mobile devices with longer battery lives, according to recent reports from New Scientist. QD displays also consume lower power and have richer color than conventional OLED, claim some analysts. The analysts also state that the white light produced by quantum dots has high brightness and excellent color reproduction, raising its potential to replace the backlight unit (BLU) using the LED to form the "QLED." But has the technology proved itself in actuality?" via DigiTimes

Display as a Service receives Cebit Innovation Award "The software "Display as a Service" manages to display a movie on an unlimited number of screens so that it seems to be played on a big screen. "For this the monitors do not have to be connected by cables, nor do they need to have equal display diagonal, resolution and other technical parameters as is the case with common video walls," explains Alexander Löffler. He developed the method together with computer scientists from the German Research Center for Artificial Intelligence (DFKI). The reverse case of programming screens would be possible as well. "Picture-input from various sources, like several laptops in a conference room, can be presented simultaneously on a virtual screen wall given by the software," says Löffler. ...Moreover, the researchers from Saarbrücken are already working together with screen manufacturers. Modern devices meet the technical requirements for Löffler's solution. "In the future it could be possible that neighboring football fans would build their own public viewing big screen for the football World Cup with their private monitors," says Löffler, whose doctoral thesis is also supported by the Intel Visual Computing Institute in Saarbrücken." via Phys.org

How to use imaging colorimeters to improve OLED Display Production Testing "Imaging colorimetry-based testing systems have demonstrated success in improving quality and reducing production costs for LCD displays and LED display screens. Radiant Zemax has extended these proven techniques to OLED display production testing. This new white paper from Radiant Zemax describes OLED manufacturing challenges and solutions that can improve quality and yields for OLED displays from smartphones to TVs." via Vision Systems Design

Top 5 Notable Digital Display Trends at DSE 2013 "It seems that touchscreens are becoming the norm, to be expected everywhere in all walks of life. Which leads us back to smaller signage. We talked to Iles Guran, founder and CEO of Armodilo, one of many providers of iPad- and other tablet-based kiosks that displayed their products at the show. Guran pointed out that consumers are already comfortable with iPads and other tablets. And at a lot of retail locations, customers prefer using a device that offers a little more privacy than a large videowall. ...However, he was also quick to point out that his company's solutions are not intended to replace giant videowalls, nor is there a "one size fits all" approach for every retailer. In other words, smaller signage seems to have carved out a niche in the industry based on its own merits, but it's a niche that's already shown signs of increasing growth." via Digital Signage Connection

What is PHOLED? "The true benefit from PHOLEDs comes from the fact that they can be up to four times as efficient as fluorescent variants, which would mean substantially longer battery life for smartphones which used PHOLED based displays. Convention fluorescent LEDs only emit about 25% of the excitonic energy as light, with the remaining 75% wasted as heat. But the clever engineers behind the PHOLED display developed a phosphorescent material which could convert up to 100% of the electron’s energy into light. As a result of this very efficient energy conversion process, PHOLED based displays will also output substantially less heat than other screens. ...Not only do lower temperature displays help improve the lifespan of the LEDs, but it will also lower the entire temperature of your device, prolonging the lifespan of all the components inside." via Android Authority

New Technology May Allow for High Resolution Endoscopes as Thin as Human Hair "A new kind of endoscope technology with a factor of four image improvement over any previous design has recently been demonstrated by researchers from Stanford University. It may lead to flexible endoscopes producing about 80,000 pixels at a resolution of three-tenths of a micron, as compared to 10,000 pixels at three micron resolution for current state of the art. To achieve this the researchers developed a technique that uses a multi-mode fiber (MMF) to image the field under controlled illumination delivered through a spatial light modulator (SLM). An SLM is basically a liquid crystal display which can be used to modulate different features like the intensity, phase, or polarization of the light that is passing through each of its pixels." via MedGadget

The Touch-Screen Generation "“The war is over. The natives won.” So says Marc Prensky, the education and technology writer, who has the most extreme parenting philosophy of anyone I encountered in my reporting. Prensky’s 7-year-old son has access to books, TV, Legos, Wii—and Prensky treats them all the same. He does not limit access to any of them. Sometimes his son plays with a new app for hours, but then, Prensky told me, he gets tired of it. He lets his son watch TV even when he personally thinks it’s a “stupid waste.” SpongeBob SquarePants, for example, seems like an annoying, pointless show, but Prensky says he used the relationship between SpongeBob and Patrick, his starfish sidekick, to teach his son a lesson about friendship. “We live in a screen age, and to say to a kid, ‘I’d love for you to look at a book but I hate it when you look at the screen’ is just bizarre. It reflects our own prejudices and comfort zone. It’s nothing but fear of change, of being left out.”" via The Atlantic

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

Mitsubishi Electric Free-form Screen Car Display System Developed "Mitsubishi Electric has come up with something interesting – a free-form screen car display system which is capable of projecting images on different kinds of screen, be they curve, oval or triangle in shape, in order to match the interior layouts of future vehicles. Basically, this prototype car display system will be powered by an optical engine which is capable of projecting images on curved, oval or triangular screens, in order to suit a wide range of car interiors." via ubergizmo

Will Samsung and LG Display Work Together on AMOLED? "Samsung and LG Display are both leaders in many aspects of AMOLED technology, but Japanese and Taiwanese competitors are catching up. In fact, Sony and Panasonic demonstrated OLED technologies (super top emission and ink-jet-printing respectively) which has led some to believe that Japan has taken one step leap forward." via DisplaySearch Blog

The Chromebook Pixel: leaked Google product, or clever hoax? ""The more pixels we add, the more wonderful the world," says the video's narrator. Even more tantalizing are hints that this high-res display is in fact a touchscreen. Still, it's not entirely clear whether we're seeing something that's the direct work of Google or an extremely impressive fan-made concept, but there's at least some evidence pointing to the former." via The Verge

Re-Thinking LCD Architecture for the Digital Signage Market "Since digital signage has become a recognized market, the differences in product requirements between that and a consumer TV have become more recognized. Although most differences between the two are complimentary: e.g. thinner bezels are beneficial to both consumer TV and digital signage but count for a lot more in the signage market. In some cases, however, the differences between the two are not complimentary and signage needs a solution that would be contrary to product design for a TV. One example is viewing angle." via Flat Panel Display Blog

MSC offers embedded graphical LCD design day "MSC Gleichmann will be running a one-day workshop covering hardware and software design of graphical LCD user interfaces in embedded applications. It will focus on the Renesas 32-bit RX-series microcontroller development environment and will take place at the National Motorcycle Museum in Solihull, West Midlands on Thursday 14 March. The morning session will explain the fundamentals of driving a graphics LCD, first showing how this can be achieved using the RX62N Starter Kit to directly drive a WQVGA TFT display with touchscreen interface and then looking at how the software can be adapted for other similar standard displays." via ElectronicsWeekly

Apple Reviewing New Kind of Optical Film that Outshines OLED "Due to the film's low cost, it could replace other, more expensive films that have been used to create LCDs. Toyobo Co., a synthetic fiber manufacturer, will begin producing the film in April, at a scale of 10,000 tons per year." via Patently Apple

Trends in Capacitive Touch Panels "Cypress Semiconductor has been supplying capacitive touchscreen controller IC solutions since 2008 and has maintained a database with the sensor parameters and layer structures for each customer project that has entered mass production since then. Based on actual design project data from this database, we have derived some trends on the prevailing parameters of 'on-stack' sensors over the 2009-2012 timeframe. 'On-stack' refers here to structures where the touch sensor layers are supplied by standalone (ITO) sensor vendors and are combined with the display module after completing manufacturing of the display." via Electronic Design

Invisible Smartphone on the Horizon? "Using technologies developed for displays, a Taiwanese company is showing off prototypes of a phone made of glass. ...Polytron has a long history with display technology, and markets a product as “privacy glass.” The liquid crystal molecules in the glass are arranged randomly when the current is off, but when it is on they line up and allow light to pass through. So this phone would be invisible until it is turned on. " via Discovery News

Can your 3D projector do that? "Watching in the dark will always be better than having a light on, but projectors today put out much more light than those in the past. For example, one of the 750HD’s selling points is the high level of brightness it provides 3,000 lumens of white brightness. And because the 3D view is “active” (liquid-crystal glasses used, not polarized), the full resolution of the image is maintained. The result is a more realistic and true-to-life 3D image as well." via 3DTV.com

How CNET tests TVs "Uniformity: With LCDs and rear-projection sets, we use this section to address backlight uniformity across the screen, making subjective observations with full-raster test patterns, letterbox bars and flat-color scenes, such as shots of skies, from program material. We also talk about off-angle viewing in this section, using similar material and subjective comparisons. Plasma TVs usually have effectively perfect uniformity and off-angle viewing, so we don't typically don't include this section in plasma reviews--but we will if the plasma's uniformity is atypical to our eye." via CNET

‘Peacock’ color for screen displays "In a peacock’s mother-of-pearl tail, precisely arranged hairline grooves reflect light of certain wavelengths. That’s why the resulting colors appear different depending on the movement of the animal or the observer. Imitating this system—minus the rainbow effect—has been a leading approach to developing next-generation reflective displays." via Futurity

CES 2013 "It was impossible to walk through the CES without being bombarded with screens. Large screens, 3D screens, OLED screens, UHD/4K screens, 'smart' screens and all combinations of the above. With regard to large screens, the 110" 4K LCD screens on display from a number of China-based brands, including TCL and Hisense as well as Taiwan-based Westinghouse (in a hotel suite), were clearly hard to miss given not only their size, but the prominent position of the stands in locations that would have had major Japanese brands in those places in years gone by. That alone is part of a trend: Chinese brands will no longer be relegated to second place brands or OEM suppliers to others." via hiddenwires

Touchscreen suppliers snub notebooks in favor of smartphones, tablets "The unproven demand for touch screens on notebooks and the high-end specifications for touch on Windows 8 notebooks have contributed to touch-screen suppliers' reluctance to shift production from high-volume smartphones and tablets, noted Richard Shim, senior analyst with NPD DisplaySearch. ...In addition, there is a shortage of ultra-slim panels for ultra-slim notebooks due to the technical challenges and expense of making the panels. "The challenge from a production standpoint is that manufacturing ultra-slim glass--0.4mm and thinner--is not only difficult, but handling and transporting such fragile glass requires special equipment. Only two panel suppliers, AUO and Innolux, are taking on the extra expense of using ultra-slim glass to offer panels in any significant volumes," Shim said." via FierceMobileIT

Apple surprises with new solar / touchscreen patent "What’s interesting about this patent is that the solar panel would also operate as the touchscreen itself, rather than as two separate units, observed Forbes. Most touchscreens today use either a resistive (pressure-sensor) or a capacitive (conductive-sensor) screen to respond to touch input. The iPhone and iPad use capacitive touchscreens, for instance. However, the new patent takes a fundamentally different approach. “The integrated touch sensor array and solar cell stack-ups may include electrodes that are used both for collecting solar energy and for sensing on a touch sensor array,” according to Apple’s abstract. “By integrating both the touch sensors and the solar cell layers into the same stack-up, surface area on the portable device may be conserved. In addition to being used for capacitive sensing, the integrated touch sensor and solar panel configurations may also be used for optical sensing.”" via CleanEnergyAuthority

ZBD's epaper customer displays "Berkshire-based ZBD started life in 2000 as a technology spin-out of UK research lab Qinetiq, launched to exploit zenithal bistable displays, hence the company name. ...Unlike E Ink displays, ZBDs can be made on a standard high-volume LCD manufacturing line with little modification. The image quality is high-contrast and easily read, like an LCD digital watch, but does not achieve the ink-in-paper look of E Ink in an eReader. ZBD has re-invented itself as an electronic shelf-edge labelling firm by combining its displays with a low-power radio receiver in units ('epops') that offer five years of maintenance-free operation from an internal battery." via ElectronicsWeekly

Add OLED screens to your fingernails with NailDisplay "It's only a prototype right now, but a group of engineers at the National Taiwan University in Taipei think that using fingernail-mounted OLED screens could solve a number of UI problems plaguing today's gadgets. For instance, if a person is typing on a touchscreen smartphone, the NailDisplay could show what virtual key your thumb is on (and obscuring), essentially making your typing experience a "transparent" one." via DVICE

Jaguar Land Rover engineer discusses HMI display technology "The key differentiator that is holding back displays in the automobile is that of the environment. The harshness and variety of environmental extremes means that standard consumer display's can't be used, therefore specific development projects need to take place. I expect that the increased resolution trend will eventually migrate across to cars, but this must not be done at the expense of performance and in particular brightness - which in a fixed position system is critical to ensure performance in all ambient lighting conditions, this is something that consumer devices are not particularly good at." via Display Alliance

Penetration rate of touch screen technology used in LCD monitors expected to increase in 2013 "The global penetration rate of touch screen technology used in LCD monitors is expected to increase to 8-10% in 2013 largely due to the release of Windows 8, according to sources at ViewSonic. The penetration rate is expected to reach the percentage by the end of the year after climbing from 3-5% in the first quarter 2013 largely due to LCD vendors' plans to continue releasing products that are Windows 8 compatible, said the sources." via DigiTimes

Flex-o-Fab: a new 3-year EU project that aims to help commercialize flexible OLEDs within six years "The Flex-o-Fab project will draw on technologies and expertise already used to produce glass-based OLEDs and flexible displays. It will look to migrate existing sheet-to-sheet processes to roll-to-roll (R2R) production to further reduce costs and enable high-volume production." via OLED-Info

Sharp IGZO to Transform Displays "The cascading effect of these two advantages over A-Si are stunning, and Sharp is taking full advantage, as evidenced in the CES booth. The big advantage in mobile displays comes in power savings, as the larger aperture ratio allows for far fewer LED backlights to achieve the same brightness levels. But beyond the obvious power savings from fewer backlights, the high electron mobility from Sharp IGZO also allows the display panel to modulate the on/off state (at about 100 Hz) and still maintain the image on the screen, according to Chris Frank of the Sharp Camas Labs in Washington State." via Display Central

Today's thinner LCDs can show uneven lighting, even in bright scenes "LCD screens have often shown some backlight non-uniformity (called mura), because an LCD panel can let the backlight leak through more in certain spots than in others. Normally, this appears as an uneven cloudiness that usually can be seen only when the screen image is dark or completely black. But as TVs get ever thinner, we've seen a new problem that can cause even more noticeable type of non-uniformity, which, at its worst, can be distracting even in bright scenes." via ConsumerReports.org

Car Makers Seize New Display Technology "Daimler AG's Mercedes-Benz is torn on whether to implement the head-up display technology in its models. Its revamped E-Class sedan, which debuted at the Detroit auto show this week, is chock-full of new safety technologies such as a pedestrian-detection system, but doesn't include a heads-up display function. "There is still an internal debate [within Daimler] about it at the moment," said Joachim Schmidt, Daimler's global sales chief." via The Wall Street Journal

High res displays revolutionize user interfaces "In the past, UI designers had to think about what would look good on a display. Now these designers just need to figure out what looks good. This small shift in design mentality has unlocked the creativity of many on what a modern interface should look like, and we have only seen the start of it." via The Retriever Weekly

Kent Displays Listed As Manufacturer “Of Note” 2013 "A pioneer in the liquid crystal display industry, Kent Displays has transformed itself from a research-based organization into a business-to-consumer company. Its plastic LCDs, manufactured under the trade name Reflex, are used in a variety of applications in growing markets such as writing tablets, electronics skins and credit card displays. Among Kent Display’s products is a line of e-writers — the Boogie Board tablets — which were introduced in 2010 by Improv Electronics, Kent Displays’ consumer product subsidiary. In its first year in production, Boogie Board tablet sales exceeded forecast by 10 times because of their successful entry to the Chinese marketplace. By 2011, Boogie Boards were being sold in India. Today, the company is exploring other global markets for expansion. Learn more at www.kentdisplays.com." via Smart Business

E Ink accused of asset-stripping Hydis "The chief bone of contention for Hydis workers is the suspicion that E Ink is asset-stripping the company by selling its core technology — more specifically, the license for Hydis' LCD technology which is considered to be just a few notches below top display makers such LG Display — to rival companies. The act itself may be legitimate, but in that case, Bae insists that the government must initiate legislation to prevent such transfers of technology in the future. ...This would not be the first time that Hydis suffered at the hands of a foreign owner. Prior to E Ink's acquisition in 2008, the display maker — formerly a unit under Hyundai Electronics, the precursor to Hynix Semiconductor that was acquired by SK Group — had been exploited by China-based BOE Display." via The China Post

“Moth’s Eye” Approach Will Reduce Screen Reflections and Glares "Moth Eye technology will be far more advanced than Apple’s Retina display, which develops screens based on the highest threshold of human sight that can distinguish between the pixels on a screen. While Steve Jobs touted Retina display technology as the maximum threshold of human sight, a recent rumor has it that Samsung Electronics will use diamond-shaped pixels in its soon-to-be Galaxy S4 instead of the usual Pentile-Matrix pixel display (while also producing a pixel density of 440ppi, or pixels per inch)." via The Droid Guy

Samsung hits OLED screen milestone "While it took Samsung four and a half years to reach the initial 100 million production mark for OLED panels, the next 100 million units were produced in just eleven months, and the last 100 million units were produced in only seven months. Samsung held a ceremony to commemorate the 300 million production milestone at Samsung Display City located in Asan city, Chungcheongnam-do, in South Korea, which was attended by its president and more than 300 other employees." via itbusiness.ca

Design Touchscreen-Based Handheld Systems For Low Power Consumption "Designers can stretch the operating battery life of handheld devices through judicious management of the operational states. Touchscreens, which are now nearly ubiquitous, make a good example. The operating conditions for a portable device, with the variety of applications it can support, generally can vary from intensely busy to nearly idle in a moment’s time. By utilizing knowledge of how a device is being used, the power consumed by the touchscreen can be more efficiently managed." via Electronic Design

Toray’s touchscreen film self-repairs scratches, cuts down on fingerprints "What Toray has done is manage to apply the anti-fingerprint solution to their self repairing film. So now you can have a fingerprint free touchscreen that also recovers from any minor scratches. Toray also updated the anti-fingerprint technology to make it easier to remove any dirt that does build up, however, in doing so the film doesn’t work quite as well as last year’s wrinkled nanometer surface method." via geek.com

Has Apple finally abandoned its sad claim to the 'Multi-Touch' trademark? "Apple's used "Multi-Touch" since literally the first minute Steve Jobs uttered the word, with a conspicuous pause between syllables and a handy slide behind him displaying the hyphenated form. The goal, as with any trademark, was to convince the public that "Multi-Touch" on Apple devices is a proprietary technology somehow distinct from all the other multitouch displays in the world. If you squint right and imagine you're a hotshot young attorney with a bad BMW habit, it sort of makes sense, in the same way that "E Ink" makes sense as a trademark. But it was always unfortunate: here's Apple, the leader in minimal design, allowing its lawyers to brutalize the perfectly functional word "multitouch" with two capital letters, a hyphen, and a superscript. Gross." via The Verge

Displair gives you a touchscreen out of thin air "Air flows out of the device, interacting with water drops to form a screen where you can beam images from a computer or tablet. But this is no mere projection screen, it's a fully interactive display, as I found it when I was able to play a game of Fruit Ninja just by waving my hand across the Displair's virtual screen." via PC World

CES 2013 OLED summary "But the most interesting OLED TVs didn't come from LG and Samsung this time - but from Sony and Panasonic. Both companies unveiled 56" 4K OLED TV prototypes. The two companies are collaboration on OLED technologies, and Sony made the TFT on Panasonic's set - which probably explains why both unveiled TVs in the same unique 56" size." via OLED-Info

It's official: 3D is dead "There are no more 60-foot posters with people exploding out of flatscreen televisions. The super glitzy marketing videos now relate to the far more tangible benefits of higher resolutions, curved displays, and the beauty of OLED. The show floor space dedicated to three-dimensional imagery has been decimated, relegating a dubious technology to its proper position as a sideshow rather than a leading cause to upgrade your TV." via The Verge

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

Show envisions curved displays, controls "Given enough imagination, engineers could figure out how touch controls or displays could be helpful on the curved handle of a cup of coffee, said Mariel van Tatenhove, marketing director for touch materials for San Jose's Atmel Corp., a developer of microcontrollers, capacitive touch controllers and touch sensors. "We used to think the world was flat, but it's not," said van Tatenhove, who was showing off the company's paper-thin and bendable touch sensor called XSense. "Why shouldn't devices be either?"" via SFGate

Harman Wants to Put an Augmented Reality Display in Your Car’s Windshield "Harman has developed an augmented reality display technology that give you real-time information in your windshield while you drive. It's like Google Glasses for your ar except that the product is actually about to launch it (or so they say...). And Harman promises you won't crash while using it." via Gizmodo

Two Advanced LCD Technologies Appear in Soon-to-Ship Consumer TV Sets "Sharp didn’t really try in its big press conference, simply saying that in addition to its coming 4Kx2K TVs, the company was introducing an FHD Quattron TV that produced images with close to 4Kx2K sharpness. ...Very briefly, because a Quattron pixel contains four subpixels (red, green, blue, and yellow) instead of three, any given color can be created with more than one combination of primaries. This redundancy can be used to create two luminance peaks per pixel instead of the traditional one luminance peak per pixel. Thus, the panel can produce a true 4Kx2K image even though it contains only 2Kx1K (four-primary) pixels." via Display Central

Tactus tactile LCD "It’s a flexible panel sandwiched atop a touchscreen that uses liquid to inflate and deflate buttons that provide actual tactile response on devices like smartphones, tablets, and kiosk computers. Fast forward to this week and Tactus is on hand at CES 2013 where it’s showing off a 7-inch reference tablet that features the slick morphing keyboard. Like an e-Ink display, the Tactus buttons only require power during state changes." via Geek.com

How to deploy digital signage in transit "Solar Clearing of the LCD screen also is a concern. With direct sunlight and a backlight at full brightness, the LCD crystals receive a large amount of heat and could go through a phase change causing black blotches on the screen. This solar clearing will cause degradation in the display, thereby reducing the operating life." via Digital Signage Today

Flat panel makers safe from rising NTD "Chang said the near term foreign exchange rate fluctuations are unlikely to hurt Taiwanese screen makers badly, but he is more concerned about long term movements if the local currency continues to climb. Chang said another silver lining is that the weakening Japanese yen has served as a factor to reduce the impact from a rising New Taiwan dollar as local flat panel makers are able to take advantage of a cheaper yen by importing components from Japan." via The China Post

DNP creates bezel-narrowing LCD cover "InvisiBezel can be mounted on top of standard “narrow-bezel” LCD panels. The edges consist of prisms that optically stretch the pixels at the edge of the LCD panel to conceal the bezel. It also protects the panels from scratches." via InAVate

Samsung Again Teases Flexible Displays, But Will Anything Come of Them? ""Samsung and a few other vendors have been teasing the market for some time on flexible displays but so far as I can see, their yapping hasn't done much to create buzz around the idea, let alone actual demand," said Charles King, principal analyst at Pund-IT. "The more attention they receive, the more flexible displays look like a classic 'solution in search of a problem.' Unless Samsung and other involved parties can define some compelling need or use case, flexible displays are likely to become one of those long-discussed yet quickly forgotten misadventures."" via Sci-Tech Today

This Vomiting Robot Is Really A Next-Generation Display Technology "Petman, the eerily lifelike walking droid manufactured by Boston Dynamics, may look like a Terminator prototype, but it’s actually designed to test chemical protection clothing for humans. ECCErobot began as a testbed to study how our brains control our floppy, fragile bodies. And Larry, god bless him, is basically a display technology for studying the contagious properties of aerosolized norovirus (a nasty bug that spreads from projectile vomiting).

OLED TV Arrives "The companies are tackling the OLED in different ways. Samsung is using three OLEDs—one red, one green, one blue—for each pixel; LG is using white OLEDs throughout, creating subpixels with colored and white filters. O’Donovan says he thinks, at least in the short term, that LG’s white OLED approach “will be better for yields and will create a more uniform color for the whole panel.”" via ieee spectrum

Panasonic Halts Plasma R&D "Panasonic is reportedly due to halt R&D activities for its plasma TVs to concentrate on developing OLED technology. ...In fact, plasmas could be phased out for good in 2014 to make way for upcoming OLED technology, which boasts all the benefits of plasma and LCD (infinite contrast, wide viewing angles, good response times, etc.) without the drawbacks." via Digital Versus

Small, medium-size AMOLED displays doubling by 2015 "Mass adoption of AMOLED technology, though, faces hurdles due to the higher cost and technical difficulty of manufacturing -- successful entry takes five years on average, according to the firm. "Prior to the start of mass production of AMOLED displays for mobile phones, only passive-matrix OLED (PMOLED) displays were available, mostly used in applications such as mobile phone sub-displays, automobile displays, and some industrial and niche applications," Chung stated." via Solid State Technology

The Difference Between Makers and Manufacturers "In Producing Prosperity: Why America Needs a Manufacturing Renaissance, Gary P. Pisano and Willy C. Shih, professors at Harvard Business School, list critical technologies in which the United States has lost or is at risk of losing its manufacturing prowess. Among them are rechargeable batteries, liquid crystal displays, and semiconductors (70 percent of the world’s foundry capacity is in Taiwan). It is no longer feasible to make e-ink readers in this country, though the technology was invented here. Shih rejects the notion that innovative products can reliably emerge when designs are shipped off for others to produce." via MIT Technology Review

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

Apple May Use IGZO Display Technology on 2013 iPhone and iPad Releases "A rumor suggests that Apple, Inc. and Sharp Corp. are negotiating plans for the former company to use the latter’s IGZO (Indium Gallium Zinc Oxide) technology in its next-generation iPhones and iPad tablet computers. While this agreement could be a potential game-changer for Apple, low yield rates on Sharp’s end has forced Apple to consider other display manufacturers in Asia to ensure healthy supplies of display panels." via Eastern Morning Herald

A Closer Look – MIT Lab’s 8D display "The 8D display is just of several inventions to overcome the prohibitive bandwidth requirements of holographic displays, all without the need for eyeglasses, using optimized optical hardware and co-designed "compressive" image-encoding algorithms. To date, MIT have explored the use of such "compressive displays" that are primarily composed of multiple layers of high-speed liquid crystal displays (LCDs)." via 3D Focus

Electrowetting combines the best of LCD and E Ink "The problem is that the polarization limits both the viewing angle and the light coming from the backlight. Together, those optical layers—the polarizers, the color filters, and so on—waste more than 90 percent of the backlight’s output. Electrowetting limits this loss by dispensing with the polarizers." via ieee spectrum

Liquid Crystal Finding Could Lead to New Computer Screens "University of Massachusetts Amherst mathematician Robert Kusner teamed up with researchers at the University of Colorado to conduct three-dimensional liquid crystal experiments. According to a press release, “The work is expected to lead to creation of new materials that can be actively controlled.” ...“These findings lay the groundwork for new applications in experimental studies of low-dimensional topology, with important potential ramifications for many branches of science and technology,” Smalyukh stated, noting that the finding could lead to upgraded liquid crystal display (LCD) screens in televisions and laptops that let them interact with light in new ways." via The Epoch Times

Uni-Pixel: Possibly The Best Investment For 2013 "In order to fully understand Unipixel's opportunity, one must first understand the market - touch screens. ...Current 'conductive layers' are made from ITO (Indium Tin Oxide) which is horribly flawed. Firstly, Indium is expensive, increasing from $300/kg to $800/kg in the past 3 years. ...Due to the brittleness of ITO, this cost gets exponentially more expensive for larger screens (such as tablets or laptops, or larger smart phones). This is where Unipixel steps in with the UniBoss product." via Seeking Alpha

LG Flexible e-Paper Fails to Change the e-Reader World "Why didn’t this screen technology ever catch on in the e-reader world? Amazon, Barnes and Noble, Kobo, Bookeen, and Bebook all use e-Paper made by e-Ink Holdings. This company has had a stranglehold on the entire e-reader segment. With the industry gravitating towards illuminated screens and e-Ink Triton 2, there aren’t any takers for LG." via Good Ereader

New E-Notepad by Sharp brings paper notebooks closer to their doom "The strongest point of the WG-N10 is the accuracy of its response when used with a stylus. It has a self correction system that adjusts the output lines accordingly as the stylus "writes", and can accurately display written notes even in the centimeter range. The reflective display even adds more intuitiveness to the unit, since it can be used just about anywhere that you can use an ordinary notebook, only you don't use up paper and ink!" via VR-Zone

Patent Issued for on Demand Calibration of Imaging Displays ""The steps further include receiving luminance and color values from a plurality of photosensors associated with the display screen, where the photosensors detect distinct luminance and color levels at the different regions of the display screen. The steps also include determining, from the detected luminance and color levels, a plurality of luminance and color correction factors by comparing the detected luminance and color values to reference luminance and color data. The steps additionally include applying the determined luminance and color correction factors to the different regions of the display screen so as to adjust luminance and color of the display screen at the different regions, where each of the different regions is spanned by a corresponding measurement field."" via Equities.com

Firewall: A Depth Sensitive Interactive Wall "Firewall is an interactive installation, a seemingly normal wall that is actually a stretched spandex surface which acts as a membrane interface sensitive to depth. People can push, touch, move and create fire-like visuals dynamically depending on the speed, pressure, depth and movement of the interaction with the spandex surface." via Digital Buzz Blog

Penn team making waves with liquid crystals "Despite their name, such defects are highly desirable. If the location of the defects can be controlled, the change in pattern or orientation can be put to use. In the case of a liquid crystal display, for example, the crystals’ orientation in different regions determines which parts of the screen are illuminated." via Penn Current

Touchscreen offers new opportunity for PC brands: An interview with Acer president "Acer's internal research points out that a consumer, after controlling a touchscreen product for more than 20 minutes, would want to use his or her fingers to touch any display he or she sees. This indicates that touchscreen control is an irreversible trend. Acer believes touchscreen control will be a strong selling point, but it still needs more time to take off." via DigiTimes

Prismaflex launches self-powered outdoor displays "Prismaflex, the international outdoor media specialist, has created the first out of home advertising display that is entirely energy self-sufficient, with the launch of its solar-powered Autonomous Scroller displays. The breakthrough has been enabled using a transparent photovoltaic film that taps the sun's energy to power both the scrolling mechanism and the LED lighting used by the Autonomous Scroller display." via PrintWeek

Steve Wozniak's IT predictions for 2013 flexible displays ""Eventually, maybe not within 2013, flexible displays will become less expensive, installed everywhere and anywhere, and change the way we interact with mobile devices and share experiences," Wozniak forecasts. "I honestly believe mobile devices will increasingly become our remote controls to the world. We’ll carry our software on our mobile devices, but display it on these communal screens – including those installed in conference rooms. Device manufacturers will continue to develop mobile devices with various screen sizes, but software will also be designed to display on any size."" via Macworld

Will This Samsung Innovation Leave Apple Out in the Cold? "As Hiner noted, “it’s when we get to the next big leap forward that the divergence between Apple and Samsung could really matter.” Samsung produces 90 percent of devices equipped with OLED, or organic light-emitting diodes, a technology thinner and lighter than LCD, and it is also the company closest to bringing flexible OLEDs to market." via Wall St. Cheat Sheet

The Anti Pinch To Zoom "In a preliminary hearing last week, a US court invalidated an Apple patent related to the famous ‘pinch to zoom’ maneuver. Pinch-to-zoom is one of the most easily recognizable of touch-screen commands, and in the days of the first smartphones, immediately demonstrated how useful a multi-touch screen could be. ...A team from the Human-Computer Interaction Design labs at the University of Washinton is working on a slightly different approach that requires even less digit work." via MIT Technology Review

2013 in view: Looking ahead at the digital signage year to come "Richard Ventura, director of sales - vertical solutions for digital signage solutions provider NEC Display Solutions of America: In 2013 we are going to see further integration of mobility and NFC with digital signage systems.

Is Heads Up Display just what the doctor ordered? "For starters, the HUD is not cybernetically attached to the eye. Instead, the HUD is a headset, currently in the prototype phase, that the ER physicians would wear during their shifts. Made by the semiconductor company Kopin, the HUD, called Golden-i, delivers information via a single tiny projection screen that rests just below the eye. That’s an important detail: the HUD’s screen is not a true display. Rather, it’s a mini-projector that beams the image onto the user’s retina." via Dot Med News

Efficient OLED gets rid of heavy metals "The lack of heavy atoms in the molecule means it might be cheaper to produce than phosphorescent OLEDs containing iridium or platinum, says Z. Valy Vardeny, at the University of Utah. ...But building a molecule doesn’t necessarily mean it will find its way into device production, writes Brian D’Andrade of Exponent, Inc., in an accompanying commentary. To be useful in production, these molecules need to be optimized to emit colors of light needed in displays, they need to be able to be manufactured into devices, and the lifetime of those devices needs to be comparable—or better than—the state-of the art, he writes." via Ars Technica

Aspen Avionics Multifunction Displays "A new Special Airworthiness Information Bulletin advises owners and operators of Aspen Avionics EFD1000 and EFD500 Multifunction Displays (MFD) of an unintentional reset occurring in certain display modes when there are a large number of Temporary Flight Restrictions (TFRs). At this time, this airworthiness concern has not been determined to be an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) Part 39." via Helicoptor Association International

Raytheon increases pilot situational awareness with Aviation Warrior wearable computer, monocle display "The Raytheon Center Display Unit, which allows militaries to replace the analog instruments in their F-16s and helicopters with a new, flat-screen digital display.

The Aviation Warrior wearable computer comes with a wrist-mounted screen, allowing pilots to see radar images, surveillance video, and maps even when on the ground." via Avionics Intelligence

Taking a Second Look at LCD "OLED is beautiful. Stunning image. But I was an early skeptic, and said then, as I say now: the LCD panel has never been stronger in the market. It will continue to dominate the TV market. Any move to OLED or other platforms is years away– well beyond any need for a reevaluation of the market. And digital signage– there is no serious rival for traditional, low-cost display. But since then, there has been more OLED fever. You've all read it. But finally, even the mass media is realizing the hype was over-done." via AVNetwork

Digital Advertising Carriers: LCD Television or LCD Monitor? "The young digital signage market has not settled on universal standards, and potential users of small-scale digital advertising networks have difficult and uninformed decisions to make. This article attempts to convince you why the choice should be made exclusively in favour of commercial LCD monitors, especially in situation when the required application is indoor or semi-indoor (for examples, on public transport stops) advertising network." via Screens Magazine

New Touchscreen Capable of Working in Bright Light "The key innovation behind hybrid tracking is that instead of blocking the infrared light emitted by external sources, it embraces it. This is implemented by tracking shadows of the external infrared light and combining that information with reflections that the built-in infrared sensors 'see' through the LCD." via Digital Signage Connection

Continuously Falling Notebook PC Panel Prices "Tablet PCs continue to capture consumers’ favor, as those who care more about content consumption than creation value portability and convenience, and thus tablet PCs are taking share from traditional clamshell notebook PCs. At the same time, economic concerns have hampered enterprise IT spending, which hits notebook PCs in particular." via DisplaySearch Blog

Samsung to reveal some exciting new tech at CES 2013? "They may unveil the new display used in this phone - perhaps the rumored 5" Full-HD AMOLED panel. Some say that Samsung will unveil a flexible panel, but I think it's quite unlikely." via OLED-Info

How electronic parts distribution and the LCD industry are changing "The electronic parts industry boomed in the 1990s and early 2000s, but major industry changes are forcing companies to adapt. In those days, middlemen such as parts brokers thrived on wide profit margins for parts and direct access to manufacturers in Asia. It was a simple formula: find buyers and sellers of parts and turn part numbers into profits. But profit margins on electronic parts have eroded with improved manufacturing and lower costs." via Display Alliance

In pixel wars, LCD has staying power, refuses to die ""OLED still has a long way to go to become a mainstream display, as it has to become bigger and improve picture quality," said Chung Won-seok, an analyst at HI Investment & Securities. "The use of OLEDs will continue to be confined to small displays at least for the next 2-3 years. Its usage as a mainstream TV panel is only likely in 2014, but even then there's a possibility of intense competition with LCD TVs as that technology keeps improving."" via Hindustan Times

OLED TV Prices May Be Lowered By New Polymer Development "For years, indium has always been viewed as the most ideal material for anodes, due to its conductive and transparent properties. But times have changed, and with the material become increasingly more expensive and difficult to obtain, researchers have been forced to try and come up with an alternative. ...Scientists working together at Iowa State University’s Microelectronics Research Center and the US Department of Energy’s Ames Laboratory believe they have finally hit on to something: a 15-year old polymer poly (3,4-ethylene dioxythiophene):poly (styrene sulfonate), known more simply as PEDOT:PSS." via HDTVtest

Touch screens go optical "The capacitive touch screen, which works by changing the local capacitance of metallic layers in the screen, reacts to very light touches and is durable but expensive to manufacture. Resistive touch screens, where conducting layers are separated by a flexible material that is compressed locally on touch, are cheaper but delicate to fabricate, especially for larger sizes. ...We devised a touch screen where light is confined in a waveguide that reacts to touch." via SPIE

Why would someone repair an LCD rather than buy a new panel? "On the other hand repairing the LCD panels is very useful for the manufacturers, because they usually get a shorter warranty period for the LCD panel than they provide to the end customer. Thus, they carry the expenses resulting from this discrepancy. The price of the repair of an LCD panel in Elsin is about 20-50% of the price of a new panel. Therefore, the total saving at mass production level is significant." via Display Alliance

USPTO may invalidate another of Apple's key multitouch patents "US Patent #7,479,949, claiming a "[t]ouch screen device, method, and graphical user interface for determining commands by applying heuristics," essentially covers iOS's ability to respond when a user is trying to scroll vertically in a document, or trying to move around within the document in multiple directions. It also covers iOS's ability to discern the difference between swiping among images in a gallery, or panning or zooming within the image. The patent is sometimes referred to as the "Steve Jobs patent," as Jobs' name is listed first among the many Apple engineers cited as inventors of the patented claims." via Ars Technica

One step closer to telepathy with BCI technology "...brain-computer interface technology (BCI) has brought us one step closer to making direct brain-to-brain communication a reality. ...What Professor James has done is record the activation pattern in the visual cortex of one individual, use a computer to convert this activation pattern into flashing LED lights of different frequencies and transmit these light patterns to the brain of another person. The result is that the second individual “sees” what the first was imagining." via Neuro Gadget

Digital Display Technology: An Introduction to Digital Signage "What kind of display will best meet the deployment needs: plasma or LCD? What are the pros and cons of each? How will digital technology change in the next five, 10 or 20 years? What about terminology — what is the language of digital technology?" via Self Service World

How RCA Lost the LCD "Today, liquid crystals are one of the most widespread technologies of the information age and the foundation of a multibillion-­dollar industry. Nevertheless, RCA’s abrupt exit from the field has largely obscured the pioneering contributions of its chemists, physicists, and electrical engineers. The events and decisions that drove the company to abandon its efforts are worth revisiting for what they reveal about the unpredictable nature of innovation—and about the tendency of large corporations to fail to capitalize on it." via ieee spectrum

Sony unveils a new monochrome 20.5" OLED monitor for the medical industry "Sony unveiled a new 20.5" monochrome OLED monitor for the medical industry. This monitor offers 2048x2560 resolution, high luminance, wide viewing angle, high contrast and deep, rich black reproduction (the black level is less than 0.001cd/M2 and 500 cd/M2 luminance)." via OLED-Info

Growing pains for new touch-sensor technology in latest iPhone, iPad "DisplaySearch said that there were production issues with the DITO film and lamination. In addition, aligning the sensors on film is more difficult than with glass, the report says. The iPad mini is the first tablet to use the DITO film touch sensor." via ZDNet

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

Head-mounted displays for reality augmentation: a survey "One question worth keeping in mind when evaluating the new crop of head-mounted devices is whether they will end up broadening the augmentational capacity of the human eye or narrowing it." via Rough Type

Knuckles and nails get invite to the touchscreen party "A modified Samsung Galaxy S3 smartphone, fitted with a small vibration sensor and running Harrison's FingerSense software, listens for the acoustic and vibrational differences between the three different types of touch. A fingertip could select an object while a knuckle tap could work like the right-click on a computer mouse and open up a submenu, for example." via NewScientist

A New Chip to Bring 3-D Gesture Control to Smartphones "The controller works by transmitting an electrical signal and then calculating the three-coordinate position of a hand based on the disturbances to the field the hand creates. Whereas many camera systems have “blind spots” for close-up hand gestures and can fail in low light, the Microchip controller works well under these conditions and doesn’t require an external sensor (its sensing electrodes can sit behind a device’s housing). " via MIT Technology Review

Sharp wins customers for new display technology "It is important for Sharp - and its deepening partnership with Apple - to keep innovating in LCD, since so many mobile display advances are centering on the alternative AMOLED technology, which is dominated by Samsung. Sharp's future success depends heavily on reducing the market power of Samsung and LG in screens, while fending off the rise of low cost Chinese suppliers." via Rethink Wireless

Chinese panel makers lobbying for higher import tariffs "Panel import tariffs are currently 5 percent, but tariffs on panels 32 inches or larger may increase to between 8-12 percent." via Morning Whistle

Flexible AMOLED display development still possible in Taiwan "ITRI said that between its upstream and downstream resources, Taiwan could have a sufficient supply chain for developing flexible AMOLED displays and could compete with Korea-based panel makers. However, that largely depends on whether upstream suppliers can boost production facilities and material amounts to create the technology, added ITRI." via DigiTimes

Taiwan touch panel suppliers pursue single-glass solutions "iDTI’s in-cell panels incorporating photo sensors in the TFT array substrate between the color filter and the polarizer can be applied to LCDs up to 100in and with 1920x1000-pixel resolution. The company is among the few that can manufacture such products using the hydrogenated amorphous silicon process. The last is compatible with current display production techniques, enabling fabrication on a mass scale." via Global Sources
