Google and Levi's Team Up For Touch-Screen Enabled Clothing "Google and Levi Strauss have teamed up for a new project called Project Jacquard, named after a Frenchman who has invented a type of loom. This new initiative will be designed and spearheaded by a small Google team called Advanced Technology and Projects (ATAP) and is taking touch screen to another level by developing touch screen enabled clothes. The touch controls will weave "interactive" textiles right into your clothes, giving any garment the ability to communicate with other gadgets and operate just like a touch screen device. “We are enabling interactive textiles,” the ATAP's own Emre Karagozler stated as part of their announcement. “We do it by weaving conductive threads into fabric.” “It is stretchable; it is washable,” he added. “It is just like normal fabric.”" via Shalom Life

How recycling LCD screens could solve rare metal shortage "The team from the School of Environment of Tsinghua University in Beijing tested 18 methods for removing indium from discarded LCD screens and displays. The methods involved crushing and grinding the LCD glass into particles less than 75 micrometres in size. The researchers then soaked the particles in a sulphuric acid solution at a temperature of 50 ºC. ...With the electronics industry selling millions of gadgets equipped with LCD screens, displays and panels of various sizes every year, there could easily be supply problems within the next 20 years if a sustainable way of indium recycling is not developed, some estimates suggest." via E&T Magazine

LG Display shows off press-on 'wallpaper' TV under 1mm thick "The 55-inch OLED (organic light-emitting diode) display weighs 1.9 kilograms and is less than a millimeter thick. Thanks to a magnetic mat that sits behind it on the wall, the TV can be stuck to a wall. To remove the display from the wall, you peel the screen off the mat. The unveiling was part of a broader announcement by LG Display to showcase its plans for the future. The company said its display strategy will center on OLED technology." via CNET

"Always-on" Color Memory LCD is Ideal Graphic Display for Wearable Products "Sharp Microelectronics of the Americas (SMA) has unveiled its 1.33-inch (diagonal) Color Memory LCD graphics display. The 8-color LCD module has ultra-low power consumption, enabling longer time between recharges for small-display products with a battery. It also enables designers to meet the growing demand for "always-on" devices – e.g., products such as smartwatches that show a full array of data at a glance without need to "fire-up" the device. The high-resolution display (LS013B7DH06) delivers smooth graphics and simple video capability, thus showcasing richer content than many cholesteric, electrophoretic, and other bi-stable, "e-ink" type display solutions – all with lower energy requirements. Transmissivity allows addition of a backlight for visibility in low ambient light." via PR Newswire

Sharp to Explore Options for LCD Panel Business "Sharp Corp. said it would seek external help to prop up its LCD panel-making business and plans to quit selling televisions in the U.S. and much of the rest of North and South America, as the electronics company steps up its turnaround plan aimed at ending steep losses. ...In withdrawing from the TV business in the Americas, Sharp will sell much of its North and South America TV operations, with the exception of Brazil, to Hisense Co., a Chinese manufacturer. Sharp had a 4.6% share in the North America TV market, far behind market leader Samsung’s 35.1%, according to research company IHS." via WSJ

Samsung creates "transparent" truck display "When driving behind big semi-trailers, people regularly take risks overtaking them because they often have to first move out from behind the truck to see if the road ahead is clear before passing. This is particularly dangerous on single-lane highways because such a maneuver can mean driving into the path of oncoming traffic. Now Samsung Electronics has come up with a way to help reduce this problem by mounting cameras on the front of a truck and large screens on the rear to display to following drivers a clear view of the road ahead. Like the See-Through System we wrote about in 2013, the prototype video system on "Safety Truck" comprises a front-mounted camera to capture view of the road ahead of the truck. Rather than wirelessly send a live feed to a transparent LCD screen installed in a trailing driver's car, Samsung's solution transmits a continuous view of the road in front of the truck to exterior monitors mounted on the rear.

Shape-shifting display projects objects out of TV screens using ultrasound levitation "The shape-changing display breakthrough is part of the Generic, Highly-Organic Shape-Changing Interfaces (GHOST) project and is the product of three years of research by the University of Copenhagen, the University of Bristol, Lancaster University and Eindhoven University of Technology. As glass cannot be bent as it will break, the researchers instead made a flatscreen display out of Lycra, which can be deformed at will. When a finger presses in on the display, a camera captures 3D depth data of the position and pressure of the finger on the screen. The researchers have developed computer algorithms that are able to detect and understand the depth information from the screens when a hand pulls at the display, as opposed to a glass screen display like an iPad, which has technology that only detects the limited area of a fingertip pressing on the glass in 2D." via International Business Times

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

Researchers develop the first skin-like flexible display "A research team from the University of Central Florida, led by Professor Debashis Chanda, has developed the first-ever skin-like colour display, which is thin and flexible enough to be used alongside fabrics. The research team’s technique could open the door to thin, flexible, full-color displays that could be built into plastics and synthetic fabrics. The technology is only a few micrometres (um) thick. That is considerably smaller than a human hair, which is typically around 0.1mm thick." via Android Authority

Samsung Display Introduces First Mirror and Transparent OLED Display Panels "The new Samsung Display OLED panel technology provides a digital viewing platform for making the consumer purchasing experience more visually engaging. When Samsung’s OLED display technology is integrated with Intel® Real Sense™ technology, a visually compelling, interactive closet or “self-modeling” wardrobe is created that can enable consumers to virtually “see” clothes or other retail items from an extremely realistic, customized perspective. Together, the two technologies create a “virtual fitting room” that will be used to help consumers vividly see themselves wearing clothing apparel, shoes or jewelry that they might wish to buy. Once retailers like Chow Sang Sang adopt the combined Samsung-Intel “personalization” virtual imaging solution, consumers will be able to go to leading stores around the world to see retail items in ways that will greatly enhance point-of-purchase shopping as we know it today." via BusinessWire

How the world’s first white laser could revolutionize lighting and display tech "Incandescent bulbs have given way to CFL and LEDs, but these lighting technologies may be destined for extinction as well. A team of scientists at Arizona State University have developed a laser that can produce pure white light that is brighter and more efficient than even the best LEDs. Technically, the laser itself isn’t white from the start, but the clever use of nanomaterials allows three colored beams to become one white beam. Lasers have always had appeal for lighting technology as they’re very bright, work over long distances, and have high efficiency. The problem has always been that lasers can’t be white. This work builds on a laser created in 2011 at Sandia National Laboratories. However, that was merely a proof of concept, not a functional device. The ASU team’s white laser produces enough light that it’s visible to the human eye. That’s a step in the right direction." via ExtremeTech

E-paper display gives payment cards a changing security code "Using payment cards with an embedded chip makes payments more secure in physical stores, but it's still relatively easy for criminals to copy card details and use them online. Oberthur's Motion Code technology replaces the printed 3-digit CVV (Card Verification Value) code, usually found on the back of the card, with a small screen, where the code changes periodically. Today, any criminal who has seen a card or overheard the owner dictating the CVV code can make an unauthorized purchase online or by phone. With Motion Code, because the CVV changes from time to time, the time a fraudster has to act is reduced." via Computerworld

LG scales up In-Cell technology for thinner touchscreen laptop displays "With the launch of Windows 8 and its awful Start screen interface, we also got an influx of touch-enabled laptops and convertibles. It was a nice feature you could happily ignore if you so wished, but it does add a little extra bulk to the display because a touchscreen requires a touch layer in the panel. However, LG is about to fix that by scaling up the touchscreen tech used in its smartphones. The technology in question is called Advanced In-Cell Touch (AIT). What it does is remove the need for a separate touch layer by integrating the touch sensor directly into the LCD panel. You no longer need to add the touch panel on top of the LCD, it instead comes as standard and reduces the thickness (by 1mm) and weight (by 200 grams) of the finished display." via Geek

Apple Watch Sapphire vs Glass Display "The world’s best [and most expensive] watches all have a sapphire crystal because sapphire is incredibly hard, making them extremely scratch resistant and almost scratch proof under normal use. But sapphire is fairly expensive, so most watches instead have a glass crystal, which isn’t as hard or scratch resistant as sapphire, but still holds up pretty well. But is there a visual difference between a watch that uses sapphire versus glass? If you were to hold up two identical watches side-by-side, the one with a glass crystal would be about 20 percent brighter than the one with sapphire (due to fundamental principles of optics that reduce its light transmission), so it appears somewhat darker and duller, particularly because the light has to pass through the crystal twice. There are some new upcoming advanced technologies that can make significant improvements on this issue that we’ll mention below. The above discussion is for traditional watches, which work by reflecting ambient light off the watch face that lies below the crystal. On the other hand, the visual consequences from using sapphire and glass are considerably greater when they are used on displays, including smartphones and smart watches, because minimizing screen reflections is especially important for displays, and sapphire has almost double (191%) the Reflectance of glass, which we consider next…" via DisplayMate

Researchers' 'Fairy Lights' Promise Floating, Touchable Laser Displays "As the researchers explain in their paper, an earlier incarnation of the technology relied on a nanosecond laser to create bursts of plasma that, when fired in rapid succession, can effectively act as a floating display. The problem, as IEEE Spectrum notes, is that while those plasma bursts can deliver tactile feedback, they can also burn you. The latest version developed by the researchers, on the other hand, uses a femtosecond laser to create a similar type of floating plasma display that's safe to touch. And while it won't burn you, the plasma will apparently still generate "shock waves" that will let you feel an "impulse on the finger as if the light has physical substance."" via Tech Times

Could this could be the big OLED breakthrough we've been waiting for? "But a joint venture by Fujifilm and nano-electronics research institute, imec, might well have turned up a more cost-effective method of producing high-resolution, big-screen OLED displays. This pairing produced photoresist technology for organic semiconductors back in 2013 and they have recently demoed full-colour OLEDs using that photoresist tech. It's a different method of producing OLED displays compared with Samsung's Full Metal Masking (FMM) tech and LG's white OLED (WOLED) with colour filters. The research is most encouraging though because it uses an OLED patterning setup that uses standard lithography tools in its manufacture." via TechRadar

Facebook’s Oculus to Pay About $60 Million for Gesture-Control Firm Pebbles "Pebbles has recently integrated its technology into the virtual-reality headset developed by Facebook’s Oculus VR, enabling users to interact with the device via hand and finger gestures. Unlike competing gesture-identification technologies, Pebbles’ enables users to see images of their own arms and hands in their virtual-reality display. In some other technologies, users can’t “see” their bodies, or only see generic digitally-generated versions. Pebbles’ technology can show unique features like clothing, scars or items held in one’s hand." via WSJ

Apple might be bringing fighter-jet technology to car windshields "The world’s most valuable company is “very likely” working on a 27- to 50-inch head-up display, a technology most famously used by jet pilots, that could project vivid icons and information for drivers while on the road, a tech analyst with Global Equities Research said Thursday morning. The curved-glass screen could also be wired with sensors and “may be completely gesture-controlled,” a stealth project that analyst Trip Chowdhry said could be Apple’s “next generation” device, after gadgets such as the iPhone, iPad and Apple Watch." via Washington Post

Switchable holographic pixel elements for 3D displays "Many so-called 3D display technologies rely on optical tricks, such as stereoscopy and reflective prisms, to give the illusion of depth. However, holograms can record, and display, all the information of the original light field using optical interference so that there is no visible difference between the optical information in the displayed image and the real-world scene. Hence the display is a true 3D view into the world (see Figure 1).1 Such an ideal 3D holographic display requires an array of multifunctional, highly dense pixels working in unison to encode phase, amplitude, wavelength, and polarization information yet with dimensions similar to visible wavelengths." via SPIE

Are quantum dots ‘ready for prime time’? Analyst says yes "Until OLEDs are ready, says Yole, “QD-LCD technology will have a unique window of opportunity to try to close enough of the performance gap such that the majority of consumers will not be able to perceive the difference between the two technologies so price would become the driving factor in the purchasing decision.” Under this scenario, the analyst believes that QD-LCD could establish itself as the dominant technology while struggling OLEDs “would be cornered into the high end of the market.” Yole acknowledges that OLED-based displays potentially offer more opportunities for differentiation but the analyst notes, “OLED proponents need to invest massively and still have to resolve manufacturing yield issues. For tier-2 LCD panel makers who cannot invest in OLED, Quantum Dots offer an opportunity to boost LCD performance without imposing additional CAPEX on their fabs.” At this year’s Consumer Electronics show, as optics.org reported, no fewer than seven leading TV OEMs including Samsung and LG demonstrated QD-LCD TVs." via Optics.org

The impact of consumer demand for cutting-edge display technology on the gases market "Currently about 20% of smartphones – the ones with lower resolution displays – use a-Si display process. Higher resolution devices and new effects such as curved displays require higher performance transistors and improvements in electron mobility. This can be achieved by switching from amorphous silicon (a-Si) transistors to low temperature polysilicon (LTPS) or metal oxide (MO), also known as transparent amorphous oxide semiconductor (TAOS). LTPS is used in about 44% of high-end LCD smart- phone displays as it has the highest performance. Due to its higher costs and scalability limitations, LTPS is less suited for large screen displays. Small displays with very high pixel resolution are produced with LTPS. High-definition large displays can be made using MO. Metal oxide semiconductors can remain in an active state longer than traditional LCD and can cut power consumption by up to 90%, which is a huge benefit." via Solid State Technology

Huge 8K panels shipping from China this year "The new screens are rocking Advanced Super Dimension Shift (ADSDS) panel technology, which sounds like some serious quantum physics kinda extra-dimensional voodoo, but is actually another liquid crystal tech allowing the wee molecules to be rotated in a more efficient way. The advantages of this technology is it's capable of dealing with incredibly high resolutions (lucky as we're talking about 7680x4320 here…) with low levels of power consumption. Another bonus of ADSDS - and why it's part of these big screens - is that it has a seriously wide viewing angle of 178º. OLED on the other hand is still sat at a slightly more limited 160º viewing angle." via TechRadar

Laser-projected mouse melds trackpad, touchscreen "ODiN is the world's first laser projection mouse, claims its creator, Taiwanese company Serafim Technologies. The device was shown off on Monday, a day before the Computex trade show in Taipei. Users who buy the product will receive a small projector that can sit on top of a table, and connects to a PC via its USB port. It works by displaying a virtual trackpad on a hard surface like a table. For users, this means they'll essentially see a small box, made out of red light, with the right and left click buttons projected at the top of the trackpad. To read the gestures, the projector has built-in sensors that can track a user's finger movements over the trackpad. The company created the product as a way to meld mouse and touchscreen functions, said Serafim's CEO GZ Chen." via Computerworld

Austrian Company Invents a Touch Screen for the Visually Impaired "Here's the gist of it: the tablet is just like an e-reader but instead of a traditional LCD display, it has one that's made out of a smart liquid that forms bubbles on the surface. When the software recognizes text from either a USB drive or webpage, it converts them into Braille letters. "We call the materials 'tixels' from 'tactile pixels' because we do not use any mechanical elements to trigger the dots," Kristina Tsvetanova, Blitab's founder, says. (Video)" via Fast Company

Everything you can do with the Force Touch Display on Apple Watch "Force Touch adds a new dimension to the watch’s user interface, a necessary one given the device’s small screen. The Retina display’s electrodes can sense when you’re tapping the screen to select an option and when you’re forcefully pressing down to bring up a secondary menu. Apple calls Force Touch the “most significant new sensing capability since Multi-Touch,” the touchscreen tech that transformed the way we interact with phones (and everything else). Apple Watch and the trackpads on the new 12-inch MacBook and revamped 13-inch Retina MacBook Pro have the new Force Touch gesture baked in, and Apple is reportedly planning to add it to the next generation of iPhones." via Macworld

Google's new finger control technology is straight out of a science fiction movie "Google showcased an early prototype of the Soli technology on stage with impressive results. Google showed how precise, fine motor skills, such as pinching the thumb and index finger, or rubbing them together at different speeds, could be used to control all sorts of things without actually touching them. In one demo, the founder of Google's Project Soli, Ivan Poupyrev, kicked a virtual soccer ball by flicking at the screen. In another, he changed the hours on a clock by turning an imaginary dial with his fingers, and then changed the minutes by raising his hands further away from the screen and doing it again." via Business Insider

Most Colorful Color Display Yet Eliminates Need For Backlight "The new display is the latest version of Mirasol, an established commercial product from Qualcomm. Instead of emitting their own light, the Mirasol displays basically use a sophisticated mirror to selectively reflect light from the environment. Researchers report in a paper published in the journal Optica that they have solved many of the biggest problems that the technology has encountered so far, decreasing the display's power demands and making it easy on the eyes in bright environments. "No more squinting at a hard-to-read display outdoors where we spend much of our time," lead author John Hong, a researcher with Qualcomm MEMS Technologies Inc., said in a statement. "We ultimately hope to create a paper-like viewing experience, which is probably the best display experience that one can expect, with only the light behind you shining on the page."" via Tech Times

Nanostructure design enables pixels to produce two different colors "The main challenge to overcome was the mixing of colors between polarizations, a phenomenon known as cross-talk. Goh and Yang trialed two aluminum nanostructures as pixel arrays: ellipses and two squares separated by a very small space (known as coupled nanosquare dimers). Each pixel arrangement had its own pros and cons. While the ellipses offered a broader color range and were easier to pattern than the nanosquare dimers, they also exhibited a slightly higher cross-talk. In contrast, the coupled nanosquare dimers had a lower cross-talk but suffered from a very narrow color range. Because of their lower cross-talk, the coupled nanosquare dimers were deemed better candidates for encoding two overlaid images on the same area that could be viewed by using different incident polarizations." via Phys.org

The Days of Squinting at Laptops in the Sun Are Almost Over "It’s a relatively new phenomenon. Back in the day—before 2006, according to this fine historical document—laptops had those squishy LCD screens that would leave psychedelic trails when you’d run your finger over them. Beyond that trippy side effect, the screens had one big benefit: Matte that were seemingly resistant to glare. Those days are gone. Pick up any laptop and odds are it’s got a glossy screen. Apple dropped the matte screen option from the MacBook Pro in 2013, and people were none too pleased. But according to Dr. Raymond Soneira, founder and president of display-testing and -calibration company DisplayMate Technologies, matte screens have their own problems." via Wired

Fiber-like light-emitting diodes for wearable displays "Professor Kyung-Cheol Choi and his research team from the School of Electrical Engineering at KAIST have developed fiber-like light-emitting diodes (LEDs), which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials. Traditional wearable displays were manufactured on a hard substrate, which was later attached to the surface of clothes. This technique had limited applications for wearable displays because they were inflexible and ignored the characteristics of fabric. To solve this problem, the research team discarded the notion of creating light-emitting diode displays on a plane. Instead, they focused on fibers, a component of fabrics, and developed a fiber-like LED that shared the characteristics of both fabrics and displays." via Printed Electronics World

Forever 21's 'Thread Screen' displays Instagram pics using fabric "Most companies seek out the latest displays for high-tech billboards, but Forever 21 has decided to take a different route for this particular Instagram project. For the past year-and-a-half, the folks at connected hardware maker Breakfast New York have been building a "Thread Screen" for the company. It's called that, because well, it's literally a screen made of 6,400 mechanical spools of multicolored threaded fabric. Those spools have five-and-a-half feet of fabric each, divided into 36 colors that transition every inch-and-a-half. They move like a conveyor belt, stopping at the right hue based on what picture they're displaying -- an infrared even scans the finished product to make sure each spool is displaying the correct color." via Engadget

Microsoft unveils computer with ‘holographic’ display "Unlike competitors, Facebook-owned Occulus VR and Samsung, Microsoft aims not to immerse the user in an entirely virtual environment but instead to bring the virtual environment into the real world in the form of what it calls “interactive holograms”. HoloLens itself, an unassuming, futuristic-looking headset, will run the latest iteration of Microsoft’s Windows operating system, Windows 10. It is one of the first computers to operate solely using voice and gesture based commands. ...The transparent lenses in front of each eye are made up of three layers of glass, each corrugated with tiny grooves to form diffraction gratings.Visible light is projected onto the lens by a so-dubbed “light engine”, and is diffracted and reflected between the layers of glass, using constructive and destructive interference of the light waves to create a virtual object in the user’s field of view." via Electronics Weekly

Apple Inc. Teams Up With Japan Display For LCD Production "Apple is reportedly in talks with Japan Display to help finance an LCD display factory in Ishikawa something next year. Japanese publication, Nikkan Kogyo, has reported that the deal is still in the works, and Apple is expected to invest around 200 billion yen ($1.7 billion) into this strategic partnership. The factory would be responsible for manufacturing low-temperature polycrystalline silicon displays utilized in the iPhone 6 and 6 Plus. Moreover, the Japanese publication states the factory will also be used to make OLED panels like the ones being used in the upcoming Apple Watch, slated for release in April." via Bidness Etc

Quantum dots: How nanocrystals can make LCD TVs better "Quantum dots are microscopic nanocrystals that glow a specific wavelength (i.e. color) when given energy. The exact color produced by the QD depends on its size: larger for longer wavelengths (redder colors), smaller for shorter wavelengths (bluer). That's a bit of an oversimplification, but that's the basic idea. Specific wavelengths of color is what we need to great an image on a television. Using the three primary colors of red, green, and blue, we can mix a full rainbow of teals, oranges, yellows, and more. Plasma and CRT televisions used phosphors to create red, green, and blue. All LCDs use color filters to do the same. There are multiple ways to use QDs in a display." via CNET

FlexEnable and Merck Take Major Step Forward in Plastic LCD Technology "A plastic LCD has been developed which is completely free of glass, instead using organic transistors on a plastic sheet, offering multiple benefits. Plastic LCDs have the potential of making products ten times thinner, more than ten times lighter and cheaper than conventional glass-based displays - all while delivering differentiating product benefits of being shatterproof and even conformal. The demonstrator was developed in a very short timeframe, and combines the key benefits of organic transistor technology (OTFT), including superior quality and yield. Ultimately, it shows a route to low-cost solutions for volume manufacturing with LCDs, the dominant display technology in the market today. FlexEnable has now demonstrated the world's first plastic LCD with active-matrix in-plane switching (IPS). It uses FlexEnable's OTFT array as well as liquid crystal (LC) and organic semiconductor materials from Merck. While the first demonstrator employs an IPS mode, this concept will be equally attractive for many other LC modes and applications such as e-readers, dynamic public signage and advertising. " via PR Newswire

Tech Time Machine: Screen and Display Technology History "'80s and '90s - Touchscreen Invades. IBM, Microsoft, Apple, HP and Atari are among just a few of the tech companies bringing touchscreen into the mainstream in this era. In 1992, IBM's Simon is the first phone with a touchscreen. FingerWorks, a gesture recognition company that is later acquired by Apple, produces a line of multi-touch products in 1998." via Mashable

Why are display makers looking to next-generation cars to drive growth? ""Previously, display makers saw little merit in auto displays because of their small volumes and slim margins ...but they are now revising their strategy as the market is growing," said Lee Byeong-hoon, a principal engineer at the South Korean unit of German auto parts giant Continental, the biggest buyer of automotive displays. Luxury cars already carry two or three displays and could have as many as nine in the near future, as safety and convenience features proliferate. Kia Motors' K9 sedan, for example, has five displays - an instrument panel, a centre information screen, two backseat displays and a "head-up" display projecting information onto the windshield. Future cars could add transparent side-window displays and replace rearview mirrors and side mirrors with screens, according to LG Display, the biggest liquid crystal display (LCD) maker." via The Star

How does rewritable paper print with light rather than ink "A new type of paper can be used and reused up to 20 times. What’s more, it doesn’t require any ink. Its designers think that this new technology could cut down on tons of waste — and save people tons of money. A special dye embedded in the paper makes it printable and rewritable. The dye goes from dark to clear and back when chemical reactions move electrons around. (Electrons are the subatomic particles that orbit in the outer regions of an atom.) The paper’s color-change chemical undergoes what are known as redox reactions. Redox is short for reduction and oxidation." via Student Science

Xerox licenses Thinfilm printed storage tech for smart labels "The Norwegian printed electronics firm Thinfilm has formed a strategic partnership with Xerox around printed storage. Xerox will license Thinfilm’s proprietary technology and make Thinfilm Memory labels, which have some very interesting characteristics. Each label, costing a few pennies, is a plastic tag that’s based on ferroelectric capacitors and allows for power-free archival storage in the 10-15-year range. This isn’t some data center technology though; we’re only talking 10-36 bits. They are however very rewriteable – the data can be rewritten 100,000 times. This means the labels are perfect for continually storing and refreshing the output of sensors." via Gigaom

Pixel QI is Officially out of Business "Pixel Qi first first established in 2008 by Mary Lou Jepson and her husband John Ryan took over the reigns as CEO in November 2012. Mary left the company in March of 2013 to become Head of Display Division at Google X. John followed her in September to become the Director Program Management at Google X. With a non-existent executive team and no display prospects for the future, for all sense and purposes, Pixel Qi is out of business. The company designs liquid crystal displays (LCDs) that can be largely manufactured using the existing manufacturing infrastructure for conventional LCDs. The advantage of Pixel Qi displays over conventional LCDs is mainly that they can be set to operate under transflective mode and reflective mode, improving eye-comfort, power usage, and visibility under bright ambient light." via Good e-Reader

How Quantum Dots Are Taking a Quantum Leap "Outside his career as a noted nanochemist, Lawrence Berkeley National Laboratory director Paul Alivisatos is an avid photographer. To show off his photos, his preferred device is a Kindle Fire HDX tablet because “the color display is a whole lot better than other tablets,” he says. What he may neglect to mention to the viewer is that not only did he take the photograph, he also helped invent the nanotechnology allowing the viewer to see those brilliant greens, rich reds, and bold blues, all while using significantly less energy. In fact, the Kindle display utilizes a technology manufactured by Nanosys, a startup Alivisatos cofounded in 2001 to commercialize quantum dots. ...Since then, Berkeley Lab’s quantum dots have not only found their way into tablets, computer screens, and TVs, they are also used in biological and medical imaging tools, and now Alivisatos’ lab is exploring them for solar cell as well as brain imaging applications." via Controlled Environments

Japan Display unveils low-power screen for smartwatches "Japan Display’s new screen could reduce power consumption dramatically since it’s designed to show color text and graphics without a backlight. Not only does that mean the screens use less power than traditional LCD displays, but they’re also easier to view in direct sunlight. Japan Display says its screens also feature memory built into the pixels of the display, allowing a watch to display a static image without using much electricity." via Liliputing

Glasses-free 3D could revolutionise advertising and cinema "In 2013, the young start-up company TriLite Technologies had the idea to develop this new kind of display, which sends beams of light directly to the viewers' eyes, andhas been working with the Vienna University of Technology to create the first prototype. Currently it only has a modest resolution of five pixels by three, but it clearly shows that the system works. 'We are creating a second prototype, which will display colour pictures with a higher resolution. But the crucial point is that the individual laser pixels work. Scaling it up to a display with many pixels is not a problem', says Jörg Reitterer (TriLite Technologies and PhD-student in the team of Professor Ulrich Schmid at the Vienna University of Technology)." via Daily Mail

Startup developing full-color holographic display for mobile devices images and video. "Fattal’s company, appropriately named Leia, will demonstrate a prototype of its new 3-D display next week at Mobile World Congress in Barcelona. Later this year it plans to release a small display module capable of producing full-color 3-D images and videos that are visible—with no special glasses—from 64 different viewpoints.Key to Leia’s technology is an invention by Fattal that takes advantage of advances in the ability to control the paths light takes at the nanoscale. He first revealed the concept, which Leia calls a “multiview backlight,” in a Nature paper published two years ago. At the time, Fattal was a researcher at HP Labs and his work applied to optical interconnects, which allow computers to exchange information encoded in light. But he realized that the idea could also be used to display holographic images, and he left Hewlett-Packard to pursue that idea." via MIT Technology Review

New Technology Will Make Fonts Look Great on Small Screens "Monotype debuted Spark, a technology that consumers can’t even buy. In fact, a measure of Spark’s success down the line might be how few, not how many, people notice it. That’s because Spark is a new software program from Monotype meant to make fonts on tiny screens, like on smartwatches and digital dashboards in cars, as intuitive and legible as the ones on your computer. The problem with fonts on small screens has to do with bitmap fonts, which get pre-coded into devices because they require less computational power. Unfortunately, those bitmap fonts are pixelated, so they won’t allow for the beauty and flexibility of rendered fonts—like Times New Roman or Helvetica—which scale more easily and can be found on bigger computer screens with plenty of power. That poses a problem for manufacturers peddling luxury goods, because a crappy screen display could easily cheapen even the most beautiful of devices.

Tackling the "achilles' heel" of OLED displays "Kateeva aims to “fix the last ‘Achilles’ heel’ of the OLED-display industry — which is manufacturing,” says Kateeva co-founder and scientific advisor Vladimir Bulovic, the Fariborz Maseeh Professor of Emerging Technology, who co-invented the technology. Called YIELDjet, Kateeva’s technology platform is a massive version of an inkjet printer. Large glass or plastic substrate sheets are placed on a long, wide platform. A component with custom nozzles moves rapidly, back and forth, across the substrate, coating it with OLED and other materials — much as a printer drops ink onto paper. An OLED production line consists of many processes, but Kateeva has developed tools for two specific areas — each using the YIELDjet platform. The first tool, called YIELDjet FLEX, was engineered to enable thin-film encapsulation (TFE). TFE is the process that gives thinness and flexibility to OLED devices; Kateeva hopes flexible displays produced by YIELDjet FLEX will hit the shelves by the end of the year." via R&D Magazine

Magic Leap CEO says Stereoscopic 3D may cause permanent brain damage "Recently the CEO of a Google backed start up Magic Leap has claimed Microsoft's HoloLens could cause permanent brain damage and to no one's surprise Magic Leap has a 'better' and 'safer' competing product. Without giving any details Rony Abovitz, the CEO of Magic Leap, says consumers should avoid HoloLens when it comes out and stick to products made with superior technology. "There are a class of devices (see-through and non-see-through) called stereoscopic 3D. We at Magic Leap believe these inputs into the eye-brain system are incorrect -- and can cause a spectrum of temporary and/or permanent neurologic deficits." - Abovitz" via WinBeta

Intel snaps up Swiss eyewear startup "Just as Google has stepped back from making networked eyewear, Intel is stepping into the gap with the purchase of Swiss startup Composyt Light Labs for an undisclosed amount. ...Most of the near-eye display technologies behind smart glasses involve some sort of trade-off. They either, like Google Glass, only show information in a small area over the eye, or are often too bulky to be practical. Composyt's smart glasses feature a patented see-through display architecture that shows images over a field of vision of 40 degrees on normal eyewear. The startup says the fact that its product works with standard and prescription glasses, has a large image size, and very high transparency will appeal to enterprises, where practicality is more important than designer style." via ZDNet

Displio Is A Tiny E-Ink Display That Runs Programmable Widgets "The Displio is the latest in a line of Internet-connected ‘displays’ designed to sit on a desk, or perhaps on a shop counter, and exhibit various online information, such as Facebook ‘Likes’, weather, number of unread email, and so on. However, although similar to the LaMetric, a fully-programmable but simple, ticker-style Internet-connected display, the Displio is considerably smaller, housing a 2.7 inch e-ink screen. Not only does this change the aesthetics considerably, and allows for a greater amount of information to be displayed, but e-ink’s lower power consumption — requiring power upon refresh only — means the Displio claims to be able to run on a single charge for up to a month." via TechCrunch

'Phorm' Case Adds Morphing Tactile Keyboard to iPad Mini "For the last several years, Tactus Technology has been working on displays that take advantage of microfluidic technology, with buttons that raise up and disappear on demand for a superior touchscreen typing experience. ...Here's how it works: there are a series of small channels filled with fluid behind an elastomeric panel (aka the screen protector portion of the case) and when activated by the slider, pressure is introduced, causing the fluid to come up through the channels and into holes, where it presses against the elastomer, physically changing and morphing the display portion of the case to create buttons. In the opposite slider position, the pressure is released and the buttons disappear as the liquid is dispersed back into the channels. (Video)" via MacRumors

Glyph head-mounted display shoots DLP images directly into your eyeballs "Rather than use an OLED display to provide an image, the Glyph uses a pair of small DLP arrays to bounce light directly onto the wearer’s retinas. This results in a very clear, very bright pixel-free image with an extremely high effective refresh rate. According to founder and chief strategy officer Edward Tang, Avegant started out with the intention of marketing its MEMS-based DLP display technology to the military, before the sudden explosion in the consumer market (driven, as Tang says, in no small part by Oculus) led him to retarget the technology at consumers. This has taken the form of a pair of chunky, oversized headphones, with the DLP components hidden in the connecting band. The idea is that you could wear the final production version of the Glyph (mostly) unobtrusively, and then perhaps flip the band down over your eyes when you’re on the train or something similar and want to watch a movie." via Ars Technica

See how different touchscreens were back in 1982 "While modern touchscreen displays use either a resistive or capacitive display to sense what your finger is touching, touchscreens in 1982 actually used a grid of intersecting infared light beams. When your finger touched the glass of the display, it would interrupt the horizontal and vertical infared light beams, sending a coordinate of where your finger was to the TV.

DARPA developing neural display interface connected to your spine "The US military’s advanced research division – DARPA – has revealed details of its ‘cortial modem’ which wants to turn the inside of the human eye into an advanced display powered by the spine. Revealing details of its plans at an event called Biology is Technology (BiT) in the US, the organisation and its director Dr Arati Prabhakar said that their eventual goal is to an internal display system that would look as if you were wearing a Google Glass-style headset, but without any external technology. According to H+, DARPA’s short term goals are to begin by creating a small device that would cost no more than US$10 of showing a basic digital display, similar to a digital clockface, through a direct interface with the visual cortex." via Silicon Republic

Top 5 problems with HMIs (Human Machine Interfaces) "Backlit villains - When choosing a HMI, parameters such as display life, picture quality, and display brightness all need to be factored into the process in correspondence to the application. There's no need to get a super bright and or high quality interface if it's only used rarely or for menial tasks. Brightness often means heat. What you have to remember is that heat seriously affects the life of a backlight and, although some HMI manufacturers try to make bulbs easy to replace, it is more common for the entire unit to be replaced instead. This is obviously more costly and so efforts to reduce overheating and overuse should be made." via Process and Control Today

Sapphire Glass: Engineering vs. Physics "This long intro is a preface to discussion of Apple's recent decision to spend $2 Billion to convert the GTAT facility into a data center. Clearly Apple is giving up on sapphire, otherwise GTAT or some restructured version of it might be useful going forward. This would tend to show that Apple ran into a Physics Problem in converting from glass to sapphire, not: cost or yield issues, design issues, tooling or such. Sapphire actually had to physics issues fundamental to the nature of the material. As described in "Big Surprise," although sapphire was harder and more scratch resistant than glass, with that hardness came brittleness. Secondly, and more importantly, sapphire has a higher index of refraction meaning that screens made with a sapphire overlay would have much higher surface reflections than glass." via Norm Hairston's Flat Panel Display Blog
