How Samsung Became the World's No. 1 Smartphone Maker "Lee Keon Hyok predicts that smartphones will indeed become commoditized, just as PCs did in the 1990s. “But you have to remember, we make a lot of parts,” he says. “The shape may change, but phones are still going to require AMOLED displays, memory, and processors. We are well prepared to meet those changes.” AMOLED refers to active-matrix organic light-emitting diodes. It’s the state of the art and possibly the only display technology that has its own K-pop song: Amoled, a catchy 2009 number by Son Dam-bi and After School. When the mobile business ceases to be profitable, Samsung will have to force its way into some other industry that requires a lot of upfront capital and expertise in mass-manufacturing. The company announced in late 2011 that it would spend $20 billion by 2020 to develop proficiencies in medical devices, solar panels, LED lighting, biotech, and batteries for electric cars. And if Samsung batteries or MRI machines don’t take over the market, maybe the chairman will set a huge pile of them on fire. “The chairman is saying all the time, ‘This is perpetual crisis,’ ” says mobile marketing chief DJ Lee. “We are in danger. We are in jeopardy.”" via Bloomberg Businessweek

Next-Gen iPad To Be Lighter, Thinner Thanks To New Display "“It’s likely that part of the thinner/lighter design will be reducing the size of the LED backlight, partly by making the display more efficient and partly by using more efficient LEDs,” NPD DisplaySearch analyst Paul Semenza told CNET in a recent note. ”The other significant change that we feel is likely is a shift to a film-based touch sensor.” ...Apple may unveil its next-generation iPad during a special press conference later this month, though a recent rumor suggested that the new tablet won’t launch until fall 2013." via BGR

Nvidia shows off stunning graphics with Kepler Mobile chip "Nvidia chief executive Jen-Hsun Huang showed off the company’s next-generation mobile chip, dubbed Kepler Mobile. Speaking today at the company’s investor day, Huang said that Nvidia made a huge investment in transforming its high-end Kepler family of PC desktop graphics chips so they can run on mobile devices. ...The new chip will be able to play high-end PC games such as Battlefield 3, pictured in the video below. That means that Kepler Mobile could enable mobile devices — smartphones and tablets — to run DirectX 11 graphics, with high-end features such as advanced shadows and lighting. To date, this hasn’t been possible — by a long shot — on mobile devices." via VentureBeat

What’s New in Multi Touch Technology? "By offering a more complete picture of how modern multi-touch technology is impacting business, the more we can better understand the environmental, ergonomic, economic and workflow enhancements that are resulting from innovations of this technology. This paper focuses specifically on new and existing users of equipment in the fields of building automation and HVAC, medical & healthcare, interactive and self-service kiosks. Moreover, it evaluates the most current technologies, features and benefits of multi-touch technology." via AIS

Pixelligent Technologies launches PixClear Zirconia nanocrystals for increased light output in touchscreens "When incorporated into existing products, the nanoadditives can dramatically increase light output and readability of modern touch screens and displays. PixClear, Pixelligent officials say, also increases the light output of products for lighting applications such as HB-LEDs and OLEDs. Prior to Pixelligent, nanocrystal dispersions suffered from aggregation and were cloudy, difficult to process, and unstable, which prevented their commercial adoption. But Pixelligent officials claim their PixClear dispersions are something new: they're perfectly clear. These clear dispersions allow Pixelligent to deliver precise control over the target applications’ optical, chemical and mechanical properties." via Solid State Technology

Planar Releases 3D BIM Models of LCD Displays and Video Walls through Autodesk Seek "Digital display company Planar Systems Inc. has announced that 3D Building Information Modeling (BIM) models of select Planar large format LCD displays and video walls are now available free through the Autodesk Seek web service. Autodesk Seek allows architects, engineers and designers to easily find, preview and download 3D models of Planar displays. They can then incorporate these models into their building plans without having to create the models themselves." via Digital Signage Connection

Touchscreen Gestures Reimagined as Sculptures "In an era when kids become intimately familiar with tablet and smartphone devices at a young age, designer Gabriele Meldaikyte captured today's touchscreen gestures in analog form. As shown in the video above, Meldaikyte's mixed-media exhibit reimagines the language of smartphone communication as sculptures; there's pinching, tapping, scrolling, flicking and swiping. ...Although touchscreen gestures are common today, there could be a shift towards more intuitive ways of control such as voice command (e.g. Google's Project Glass)." via Mashable

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

Convergent screens, content and data creating 'One Screen' to rule them all "Today the consumer disposition changes based on two things: where they are and what they are doing. For instance, a personal screen (tablet, mobile) or the screen on the wall becomes a point of wait whenever the consumer has "Dwell Time." They could be in line getting coffee or at a doctor's office. When the consumer is driving down the road, or at a train station or airport, the consumer is "On the Go," and their screen or the screen in the venue or on the roadside becomes a point-of-transit screen, where the messages are brief and about the brand. And when the consumer is either in a retail environment or just sees something they want to buy, the screen then becomes a point of sale, where the consumer is now a "Shopper."" via Digital Signage Today

China panel makers continue to improve their panel technology "China-based panel makers BOE, Tianma Micro-electronics and China Star Optoelectronics Technology (CSOT) are showing increasing signs of improved technology and are likely to start producing more high-end panel products in 2013. The panel makers currently use a-Si TFT technology to produce Ultra HD (3840 by 2160) TV panels but are looking into using IGZO technology in 2013 instead. The makers are also aiming to release 400ppi smartphone panels during the year." via DigiTimes

Computing Pioneer Alan Kay Talks About The Past, Present, and Future of User Interfaces "Part of the motivation for the PARC GUI came from our desire to have a universal display screen which could display anything — this led to the bitmap screen. One drawback of these screens and the screens today is that the visual angle of the display (about 40°) is much narrower than the human visual field (which is about 135° vertically and 160° horizontally for each eye). This is critical because most of the acuity of an eye is in the fovea (~1-2°) but the rest of the retina has some acuity and is very responsive to changes (which cause the eye to swing to bring the fovea on the change). Head mounted displays can have extremely wide fields of view, and when these appear (they will resemble lightweight glasses), they will allow a rather different notion of UI — note that huge fields of view through glasses will help both 2-1/2 D and 3D graphics, and the UIs that go along with them. This suggests many new design ideas for future GUIs, and they will slowly happen." via Time

Novel Plastic Film Displays Glasses-Free 3-D Images For Mobile "The film is basically a lenticular lens, which is a series of tiny lens elements that direct light to each eye. The nanoimprinting technology developed at IMRE makes it possible to create this type of lens on a plastic film. “The filter is essentially a piece of plastic film with about half a million perfectly shaped lenses engineered onto its surface using IMRE’s proprietary nanoimprinting technology,” said Jaslyn Law, the IMRE scientist who worked with TP on the nanoimprinting R&D since 2010, in a press release." via IEEE Spectrum

Quantum Dots in LCD Before OLED "As you read this, retailers are putting Sony model W009A BRAVIA TV sets on shelves around the USA. We’ll be seeing quantum dots in LCD before OLED for sure. It didn’t look that way a few years back, so I thought it would be interesting to bring us all up-to-date on the industrial and commercial development of quantum dot (QD) technology for display applications. ...Given the extent of industrial development, I expect to see more results soon. OLED TV has not progressed as fast as hoped and LCD makers need extra features to justify UHD prices. This looks like the right time for LCD color gamut to become a key product feature and reason for consumer upgrades." via Display Central

Interactive Holographic Video Display "Holoxica announces an Interactive Holographic 3D Display, which is a second generation prototype. The design is inspired by Head-Up Displays (HUDs), based on free-space optics with images floating in mid-air that can change in real-time. ...The interactive holographic display system comprises a Holographic Optical Element (HOE) lens, a digital controller, a motion sensor and a projection subsystem (a laser projector) imaging a diffusion screen. The HOE is about the size of a page (20x30cm) and the images are formed in real space (in mid-air) about 20cm from the hologram plane. The image are about the size of a hand (up to 7x7cm). The images can be refreshed at video rates and arbitrary images can be displayed. However, the images are formed in three distinct planes, corresponding to the colours of the lasers in the laser projector i.e. red, green and blue. ...Immediate applications of this technology include HUD-style displays and novel user-interfaces with the added dimensions of real-space interactivity. " via Holoaxica

An introduction to CPI's OLED prototype line facility "The Centre for Process Innovation (CPI) is a UK based R&D institute that helps companies develop and scale manufacturing processes. The CPI sent us the following video and update on its OLED/OPV prototype line (built by MBraun) that was designed to enable materials companies, device designers and end users to develop their technology within a fully automated, controlled environment. CPI's system supports both small evaporized and soluble OLED materials." via OLED-Info

LCD VS Plasma TVs "For those of you who care to understand the science behind [Plasma TVs], here’s how the magic happens: An electrode applies an electrical current to a small cell filled with a noble gas mixture (usually neon and xenon). This excites the gas, ionizing it and transforming it into a plasma. This plasma emits ultraviolet light – which we can’t see – but when the UV light hits a phosphor coating that lines each cell, it causes the phosphor to glow and put out light that we can see. Depending on which particular phosphor the cell is coated with, it will create a red, green, or blue glow. Just like with LCD displays, each cluster of red green and blue subpixels makes up one pixel on the screen (see header image)." via Digital Trends

QD Vision secures $20m to ramp production of components for LCD applications "According to the company, Color IQ significantly improves LCD color performance. Until now, most mainstream LCD TV designs have had to sacrifice color quality, typically only delivering 60-70 percent of the NTSC color standard. Color IQ increases typical LCD color performance by up to 50 percent and is capable of delivering 100 percent of the NTSC standard, QD Vision said." via Boston.com

George Gray, the man who made flat screens possible "Gray didn't invent liquid crystals. In fact, they are quite common; every cell in our body is surrounded by a liquid crystalline membrane. Nor did he demonstrate that liquid crystals have the flippable characteristic that makes them suitable for displays. Gray's breakthrough was to develop molecules that are flippable at room temperatures. But just like so many great innovations the road to development was far from easy largely because there was little appetite for funding research on molecules that, at the time, had no clear applications. Turning liquid crystals from curiosities into the ubiquitous technologies that they are today required both a burning need for new displays and the foresight of one of the more colourful government ministers." via The Guardian

Apple job listing confirms Apple is investigating using flexible displays in future products "Flexible display rumors have picked up steam even more since rumors of an iWatch from Apple, and just today we came across two new Apple patent applications detailing flexible devices that could change states as a user bends or twists the device. We all know Apple patent applications have never been a good indication of future product releases, but now Apple has came right out and stated in a job listing that it is indeed considering flexible displays. "Apple Inc. is looking for a Display Specialist to lead the investigation on emerging display technologies such as high optical efficiency LCD, AMOLED and flexible display to improve overall display optical performance."" via 9to5Mac

OLEDs and the beginning of the end for LCDs "In 2012 Samsung Electronics moved their LCD business units into a separate entity. One report suggests that the Taiwanese have invested $60 Billion in the LCD industry and seen a return of just $40 Billion. Some Japanese makers, despite having superb technology, have seen recent losses in some cases equal cumulative profits of the preceeding 5 to 10 years. Restructuring is therefore afoot. In the last few weeks Samsung purchased a 3% stake in Sharp. Japan Display Inc (JDI), puts together small and mid sized LCD panel manufacture units from Sony, Hitachi and Toshiba, focusing on automotive, cellphone and digital camera displays (not TV). Meanwhile, the Chinese are quickly moving into LCD panel production. For many years the top five in the LCD business, in order, were Samsung, LG Display, Innolux, AUO and Sharp. Now, as evidence of China's progress, in late 2012 Chinese BOE is number 5 for notebooks and monitors and China Star (CSOT) number five for TVs." via Printed Electronics World

Epson Concedes It Showed Reflective-LCD Projector Too Soon "The reflective LCD technology differed from conventional high-temperature polysilicon (HTPS) in that the polarized light rays don't pass through the panel but rather are reflected back at a different angle than they came in on. But the reflective technology also required a more complex polarized beam splitter to combine red, green and blue images and took semiconductor controllers out of the optical path and put them behind individual pixels." via Consumer Electronics Daily

Multi-focal AR contact lenses work for both near and far "The idea behind the iOptik, is that the contact focuses foreground light, like that from a nearby monitor, onto the center of the pupil. The background light is focused on the surrounding (annular) regions of the pupil. This resembles currently prescribed multi-focal contact lenses, which seem to work quite well — only these guys are just a little more extreme in the separation of the two fields. As shown in the video above, the image is projected directly onto display components that are integral to a pair of special glasses. Superimposing full-field 3D virtual images, which would be particularly enticing for the gaming world, would be seamless with such a device. Interaction with avatars would take place in the whole user space rather than just on a limited screen." via ExtremeTech

Japan Display has begun to see profits "Japan Display is a joint venture of Japan-based firms such as Sony, Toshiba and Hitachi with 70% of shares owned by government-affiliated institutes. Sony, Toshiba, and Hitachi each owns 10% of shares. Japan Display was established on April 1, 2012 with capital of JPY230 billion (US$2.3 billion) and currently employs around 6,200 staff. Otsuka noted that Japan Display focuses on LTPS-CMOS technology and expects panel capacity to increase to six million units in 2014 due to minimizing non-silicon based technology capacity and focus on expanding LTPS capacity." via DigiTimes

Displays defy distraction at New York Auto Show "At BMW, where analog instrument clusters are part of the classic BMW look, many of the high-tech electronic displays in 2014 models mimic analog dials. Even the BMW Concept Active Tourer premium compact car displayed at the show has a rounded albeit digital electronic instrument cluster. Here again the large display in the futuristic infotainment console isn’t a touchscreen. The only touchscreens are the two removable iPad-like displays facing the rear passenger seats, which also have access to handy fold-down trays." via TechHive

Smell-o-vision screens let you really smell the coffee "The "smelling screen", invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee, for example. It works by continuously feeding odours from vaporising gel pellets into four air streams, one in each corner of the screen. These air streams are blown out parallel to the screen's surface by fans, and varying the strength and direction of them manoeuvres the scent to any given spot on the screen." via NewScientist

Bendable screens still need a breakthrough ""There are barrier films in all sorts of products, for example food packaging, but the challenge is that OLED is one of the most sensitive materials we follow, and so creates huge challenges," says Lux Research's Melnick. Singapore-based Tera-Barrier Films, for example, has developed a way to plug leaks in the layers using nanoparticles. Director Senthil Ramadas says that after years of delays the company last month started production in Japan and aims for mass production by end-2014. "You have several challenges in the value chain," he said. "All these things need to be established, and only now is it coming out." And there's another problem: all the materials in a bendable display need to be bendable, too — including the transparent conductors that drive current through the display. Several technologies are vying to replace the brittle and expensive Indium Tin Oxide (ITO) used in most fixed displays, including nanowires, carbon nanotubes, graphene and conductive mesh." via NBCNews

Is Samsung safe from the threat of Korean war? "Samsung's primary hedge against the threat of war remains its massive geographic diversification of manufacturing assets, experts note. While Crystal Valley, a two million sq ft complex built on a former vineyard that employs about 20,000 workers, is an important cog in the Samsung machine, particularly in LCD display manufacturing, it's just a small part of the company's global capabilities. The company boasts five other plants worldwide that could pick of the display manufacturing slack in the event of a global shutdown."via Channelweb

Three-dimensional displays, past and present "The ultimate goal of display technology is to show a dynamic three-dimensional image that appears to float without a frame, much as Princess Leia did when projected from R2-D2 in the 1977 movie Star Wars. The history of 3D displays begins in a much earlier time—long before the advent of movies, holography, or electronics. It goes back to 1838 when Charles Wheatstone at King’s College London proposed the concept of the stereoscope, which works based on binocular disparity: Because our two eyes, physically separated by about six and a half centimeters, observe different perspectives of an object, the illusion of depth can be created from two 2D images whose features are slightly offset from each other. The brain merges those two images into a single 3D perspective." via Physics Today

Laser Fusion’s Brightest Hope "Here at the Lawrence Livermore National Laboratory, a U.S. national security laboratory tucked amid vineyards and undulating grassy hills about an hour east of San Francisco, the lasers of the National Ignition Facility (NIF) have already created the intense pressures and temperatures needed to get atoms of hydrogen to fuse. But NIF is trying to achieve a far more challenging goal, one that countless researchers have sought for decades. NIF’s aim is not just fusion but fusion’s equivalent of a chain reaction, a self-sustaining “burn” capable of producing more energy than is needed to get the process started in the first place. ...The laboratory has also built a small industry around damage mitigation. After a laser shot, engineers can use a telescope in the target chamber to look back through every line of optics for damage; each defect gets a number. They then use blue LEDs to program liquid-crystal-based screens through which beams pass before amplification. These screens can be made to have any arbitrary pattern of transparent and opaque areas, creating dark spots in a beam in order to circumvent damaged areas down the line. When too many defects accumulate, the engineers remove the damaged component and send it to another building, where the surface is re-treated and carbon dioxide lasers are used to etch out damage, leaving behind optically neutral conical pits. Nowadays, up to 40 pieces of optics, mostly the target-chamber focus lenses and debris shields—protective screens between the target chamber and the rest of the optical line—are pulled and sent away to be refurbished each week." via IEEE Spectrum

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

3-D computing prototype puts your hands inside the screen "Attendees of the latest TED conference got a look at a futuristic device called SpaceTop where the user views a 3-D workspace through a transparent display, manipulating the on-screen elements with just their hands. It won't be on shelves any time soon, but it does pique the imagination. ...The transparent display is equipped with a camera that tracks the user's head and adjusts the perspective on the 3-D desktop "under" it. Meanwhile, a second camera watches the user's hands and determines their position in three dimensions." via NBC News

Sharp Samsung Alliance – An Alliance of Mutual Benefits "Given that Sharp is a leader in oxide TFT technology, especially at Gen 8, it’s possible that Samsung can utilize the oxide TFT backplanes from Sharp for its AMOLED TV." via DisplaySearch Blog

Samsung's investment in Sharp could prick Apple "Apple is believed to buy about a third of its LCD panels from Sharp, and it closely relies on the company for some of its most advanced products, according to analysts. When Sharp has problems, it can slow down the release of Apple devices. So if Sharp starts to favor Apple's chief rival, Samsung, that could have big implications for Apple." via CNET

LG Display Overtakes Samsung in Global LCD Market ""LG Display has found new customers such as Sony and Panasonic and increased production accordingly," analyst So Hyun-chul of Shinhan Investment Corp. said. "It has gained a foothold for growth by supplying most LCD products for Apple's iPads in the explosively growing tablet PC market." In contrast, Samsung failed to increase sales dramatically because it is highly dependent on a single customer, affiliate Samsung Electronics." via The Chosunilbo

Air Force takes first step in replacing obsolete CRT displays in F-15E jet fighter-bomber "The project calls for eliminating obsolescent or otherwise-troublesome technology in the MPD such as CRT avionics display technology and high-voltage components. The replacement display must not affect the present MPD interaction with the Boeing advanced display core processor (ADCP) or change the operational flight program, Air Force officials say. ...The sources-sought notice is a market survey to identify suppliers with the necessary expertise, capabilities, and experience to develop a replacement MPD for the F-15E." via Military & Aerospace Electronics

5 Tech Stocks That Could Leap On Touchscreen Trends "Sollensys manufactures multi-touch sensor modules for use in the government, education, medical and consumer technology sectors. The company’s goal is to be the leading global provider of small to medium sized capacity touch sensors to the high quality and advanced technology spectrum of the touchscreen market. Through consultation with customers, Sollensys designs, develops and delivers the best possible touch sensor technology for its products. Much like Apple, Sollensys provides a high quality product through excellence in design, advanced process and production techniques, and quality control. Sollensys aims to be a leader in the capacitive touch industry, which is the company’s core technology." via Investment Underground

Flexible, transparent imaging device developed "The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet. With no electronics or internal components, the imager's elegant design makes it ideal for a new breed of imaging technologies, including user interface devices that can respond not to a touch, but merely to a simple gesture, the journal Optics Express reports. ...The main application the researchers envision for this new technology is in touch-free, transparent user interfaces that could seamlessly overlay a TV or other display technology, according to a [Johannes Kepler University Linz] statement. " via Zeenews

Wearable display meets blindfold test for sensing danger "Researchers at the University of Illinois in Chicago have developed a special set of body modules that provide wearers with extra-sensory perception as to who or what is nearby. The design could help the blind navigate safely or even support cyclists or drivers as additional safety support in traffic. Called SpiderSense, this is a wearable display that can pick up ultrasonic reflections from objects. SpiderSense can also allow the wearer, even if eyes are closed, to navigate." via Phys.org

Beyond a Human Framework of International Relations "Diplomats could soon be wearing AR contact lenses or glasses that will translate in real-time a native’s foreign language, presenting the information like movie subtitles on the lens or glass in that diplomat’s own native tongue. They will be able to translate a newspaper in another language with a glance, access data on treaties and current news events while undergoing diplomatic negotiations, or even assess the disposition of a foreign contact by using lie detection sensors and emotional cues—all displayed immediately through the AR lens interface. The technology has already been used by U.S. Marine mechanics to help them with more efficient repairs. Detailed specifications, for instance, can instantaneously be displayed through goggles when looking over an engine. Other branches of armed forces continue to use and develop new adaptations." via Diplomatic Courier

Swedish university invests in virtual medical display technology "The Sectra Visualization Table is a large, multi-touch medical display with software that facilitates interaction with 3D images of the human body created by modern computer tomography or magnetic resonance cameras. Students are able to intuitively zoom in, rotate or cut into the visualized body without using a scalpel or destroying the subject. This means that the same image can be used repeatedly, and the students are able to study the impact of various illnesses on the anatomy in a manner that was not possible in teaching in the past." via European Hospital

Why E Ink is still the leader in e-paper "Overall, E Ink electrophoretic displays win on production cost. Unlike Liquavista and Mirasol, E Ink displays are compatible with roll-to-roll manufacturing using printing technologies. This has allowed the company to rapidly scale up and produce the electrophoretic material at high volume and high yield, thus offering the product at the right price point for the e-reader market. As of today, Liquavista is still not commercialized despite the fact the technology has been in development for roughly the same amount of time as E Ink's. Mirasol e-readers were sold in East Asia but did not attract enough traction, most likely because the devices were too expensive. " via Printed Electronics World

Thoughts on AMOLED and LCD displays in 2013: Is there a clear winner? "In smartphone displays, LCD displays offer a few key advantages over AMOLED displays. Due to the "direct sunlight argument" where the Sun distorts colors and the image projected on AMOLED screens, LCD displays hold a clear advantage. At full brightness, LCD displays get much brighter than their AMOLED counterparts and also use less power in the process. They are miles ahead of AMOLED displays outside, and I'd say this is nearly an undenaible truth, and not an opinion. It's important to mention that LCD displays are only more efficient at full brightness as compared to AMOLED. AMOLED screens are more efficient all around, just not when the brightness is cranked up." via phonedog

LED-backlit display penetration rate to break 90% "LEDinside noted that there are price differences between the side-lighting mode and the bottom-lighting mode of the LED-backlit display technology. The cost of side-lighting mode is 1.5 times that of the bottom-lighting mode as the manufacturing process of the former is more complicated and calls for more expensive parts and components, it said. More than 70 percent of the TV products of South Korea's Samsung Electronics Co. and LG Corp. use the cheaper bottom-lighting mode, while Taiwan's AU Optronics and" via Focus Taiwan

A Different Concept on the Future of Helicopter Avionics "“We’ve decided that touchscreens are not the way to go, for reasons of durability and practicality,” said Grady Dees, director of technical sales for Universal Avionics Systems. MD Helicopters vice president of engineering Chris Nehls heartily agreed. “The on-cyclic cursor control keeps the pilot focused on flying, we think,” said Nehls. The engineers decided, as well, to retain certain key knobs that pilots rely on, including the heading bug knob on the panel under the PFD. “It is what pilots are used to, and we want to make the system easy to transition to,” he continued. There is also a separate EFIS control display unit located on the center console that houses all of the buttons and knobs that are conspicuously missing from the bezel of the 12-inch PFD/MFD displays." via AINonline

A Comparison of AU Optronics, LG Display and Sollensys "To sum up, AU Optronics and LG Display have demonstrated poor profitability in the last few years. However, in a fast-growing market as the touch screen panels, a quick turnaround is possible, which may reward their shareholders. It is well known that turnarounds of companies are the most rewarding situations in the stock market. According to analysts' estimates, a turnaround for LG Display is likely in 2013. Sollensys is a nascent company with high expertise and valuable patents. It is promising fast growth, but one should carefully evaluate the audited financial statements of the company when they become available, just as one should do with any investment." via Smallcap Network

Sapphire is unscratchable, unbreakable, and the next big thing in touchscreens "GT Advanced demonstrations were compelling, and the science seems to back it up. Sapphire is a naturally growing crystal and is the second hardest substance on earth. It’s so hard, only diamond-tipped saws can cut it. GT Advanced grows sapphire and then melts and hardens them into ‘boules,’ which are 115 kilogram, or 254 lb. clear cylinders. Those cylinders are then cut into cubes, which are then chopped up into slices and shapes as thin and wild as you can imagine." via Digital Trends

Mobile displays that change shape "GHOSTs are display surfaces made of malleable materials that can change into and retain arbitrary shapes so as to display output from the system or allow new actions. At the same time, GHOSTs enable users to deform, touch, or otherwise manipulate the shape of their display surface to provide input to the system. The collaborative European research project includes Sriram Subramanian, Professor of Human-Computer Interaction in the Department of Computer Science at the University of Bristol, and will bring together a range of partners from across Europe to design, develop and evaluate prototypes to define the current and future challenges of making organic user experiences." via EET India

Digital signage leading the way to a future 'Day Made of Glass' "More vivid, powerful glass substrates extend the scalability, usability and immersiveness of displays and blurs the physical and the virtual, he said. And new glass advances will create form-factor freedom that can drive application diversity and new user interfaces, making them even more intuitive and collaborative — "but we've still got far to go," he said. "Modern displays are still bricks and boxes," he said, referring to the form factors of smartphones/tablets and display screens. And because of this, the relationship between people and devices is backward, with people's environments and users' lifestyles dictated by the limitations of the device form factor, he said. People set up their living rooms to fit their TVs, and not the other way around, he said." via Digital Signage Today

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.

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

Inventing DualView: Displaying two images at the same time "The technology’s origins lay in 3D – specifically glasses-free 3D, most recently seen in Nintendo’s 3DS and 3DS XL handheld games console. Much like the 3DS, DualView combines a normal LCD with parallax barrier technology, displaying two pictures simultaneously by separating the direction of light from each pixel into two directions. But unlike glasses-free 3D, which tricks the eyes into seeing a single three-dimensional image by layering two 2D images, DualView uses the tech to display two 2D images simultaneously." via Humans invent

£25M Graphene R&D Centre With Backing from Nokia, Plastic Logic & Others "Material scientists and nanotechnologists get very excited about the potential of graphene — a one-atom-thick sheet of bonded carbon atoms which is exceptionally strong, lightweight and flexible and is a better conductor than silicon – but they are not the only ones to see huge potential in it. Nokia, Plastic Logic, Philips, Dyson, and BaE systems are among more than 20 industry partners who have pledged £13 million worth of support for a new graphene R&D centre to be established at Cambridge University. ...The new Cambridge Graphene Centre aims to develop graphene from a material with a lot of raw potential — researchers have already been looking at how graphene could improve battery capacity, and exploring its water-repelling properties — to a point where it can “revolutionise flexible, wearable and transparent electronics”." via Tech Crunch

Will Samsung use diamond or hexagonal sub pixels in their new AMOLEDs? "Reportedly, Samsung are developing hexagon and diamond shaped pixels. This means that Samsung will increase the resolution but the picture will suffer due to jagged pixel artifacts and blurring. It's probably that at such high pixel density this won't actually be noticed, but still." via OLED-Info

A Dual-Screen Smartphone "But it seems to me like the most clever, the most innovative, the most useful way to employ double screens is also the most obvious one: to turn your smartphone into a tablet. What I want–what everyone wants, I think–is the screen real estate of a tablet, with the convenience of a device that fits in your pocket. The trend right now is to try to find a middle ground with tablet-phone hybrids called “phablets” (see “Review: Galaxy Note”).

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.

Intel: It Will Be Hard to Sell Notebooks without Touchscreens. "There are a number of things that prevent touchscreen-based notebook devices from becoming widespread: one is manufacturing cost, another is heat produced by components of electronic devices (which makes touch-screens uncomfortable to use). The pricing of touchscreens is something Intel intends to take care of this year, but touch-sensing panels will still be pretty hard to implement while maintaining very thin screens that are used on today’s mobile PCs." via Xbit Laboratories

Apple lacks display aspect ratio consistency "Apple went from an aspect ratio of 3:2 to 16:9 and from a pixel format of 960×640 to 1136×640. 960×640 was itself unusual, surrounded by a world of smartphones with 800×480, 960×540, 1280×720. Those are unusual too, except for 1280×720. But 1136×640? That’s ridiculous; it’s good for nothing." via Display Blog

Materials for touch screens in short supply "High demand for the touch screen material has now resulted in about a 30% shortage, which is also putting China-based touch panel makers at a loss. Recently, Truly Optoelectronics general manager Jian-hua Li arrived in Taiwan looking for additional suppliers of thin-film type touch screen materials." via DigiTimes

Transparent memory for head-up displays a step closer to reality "Researchers at Rice University are designing transparent, two-terminal, 3D computer memories on flexible sheets that show promise for head-up displays and electronics. The technique is based on the switching properties of silicon oxide (SiOx) and the use of indium tin oxide (ITO) or graphene as the electrodes." via Laser Focus World

Microfluidic Technology Enables New User Interface "The Tactus Tactile Layer™ panel was developed to provide a next-generation user interface with real physical buttons, guidelines, or shapes that rise from the surface of a touch screen on demand and can be employed without visual confirmation from the user. The Tactile Layer component is a completely flat, transparent, dynamic layer that sits on top of the touch sensor and display. The thin layer deforms and buttons or shapes of a specific height, size, and firmness emerge from the surface when triggered by software API, a proximity sensor, or an other event." via The Society for Information Display
