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

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

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

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

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

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

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

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

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

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

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

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

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

Head up or head down: Debate avionics displays with Avionics Intelligence and Avionics Europe "The staff of Avionics Europe 2013 announces a new and exciting addition to the conference program. The 2013 event, to be held Feb. 20 and 21, 2013 in Munich, will feature an interactive panel discussion on a hotly debated topic: head up vs. head down displays." via Military & Aerospace Electronics

Anorexic display devices "Thinness is a distinct advantage when it means reduction of layers and consolidation, especially in the display. The new in-cell touch screens in the iPhone take out a layer. Every layer in a display adds two surfaces and each surface can usually be counted on to contribute 4% in surface reflections that reduce sunlight viewability and image contrast in general. Much of the visual improvement from the iPhone 4 to the iPhone 5 can be attributed to this feature." via Display Alliance

Hot off the Kindle Paperwhite, E Ink looks to the future "No matter how good the technology gets, e-paper will never replace LCDs in high-end, media-rich tablets, but E Ink doesn't worry too much about that: through mergers and acquisitions, the company has come to own Hydis, a Korean firm with a rich patent portfolio in LCD technology that's notably been licensed by Apple display suppliers AU Optronics and Sharp." via The Verge

Panasonic Exiting TV? "Although Plasma had been written off as a declining technology some years ago, the re-emergence of 3D sparked something of a revival. Due to the fact that 3D trades temporal resolution (response time) in order to get 3D, with its much faster response time, Plasma was a better fit for modification to 3D. Panasonic jumped on this and launched a line of studio production equipment to enable wider adoption of 3D. " via Flat Panel Display Blog

iPhone 5 Display: Now 16:9 with full sRGB Coverage "Touch sensing has to be time multiplexed with display driving otherwise the touch signal might be entirely lost in noise. At the same time, touch sensing is often around double the frequency (120–175 Hz) of display drawing (60 Hz), so this has to be done carefully during quiet periods, and thus that required communication and integration. The iPhone 5 uses a combination of TI and Broadcom controllers to do display controller and touch sensing, where previous generations of iPhone simply just used a single chip TI solution." via AnandTech

AUO to benefit the most from FFS technology agreement with Hydis Technologies "The observers also said AUO's overall product mix will be improved and that AUO will even have an advantage over E Ink when it comes to securing orders in the long run. Securing orders for small- to medium-size panel products will be particularly important for panel makers as the products are growing in demand and thus creating more competiiton in the market, added the observers." via DigiTimes

Sharp bets recovery on IGZO LCD panel biz "Sharp already makes IGZO displays for Apple's iPad tablet at its Kameyama plant since April, the report added. Sharp said IGZO displays, which consumes only 10 percent to 20 percent of the power required by conventional panels and are also thinner, are better suited for ultrabooks, Reuters noted." via ZDNet

The top 5 questions to ask when choosing a video controller "5. Are there any additional thermal or other environmental requirements? Though made of similar components serving similar purposes, video controllers are not created equally. They can be made to withstand high temperatures and humidity, severe vibrations and shock, and even strong magnetic fields such as those found in MRI (Magnetic Resonance Imaging) rooms." via Display Alliance

4K is now called Ultra HD "4K TVs are coming but you will call them Ultra HD TVs – says the Consumer Electronics Association (CEA). ...CEA also requires TVs to have at least 3,840 horizontal pixels and 2,160 vertical pixels to use the Ultra HD label. No words on what 8K will be called by the CEA but 8K is still many years away so we are not too concerned about this." via Flat Panels HD

The Information Display News Roundup For 10.1.2012

Image via Slash Gear

Kindle Paperwhite technology explained by Amazon in video "The light you’ve got here around the rim of the display is captured and reflected across the face of the area you’re looking at. This area is called the Light Guide – it’s nanoimprinted and acts like a fiber-optic cable, blasting light through itself and down towards the capacitive touch screen instead of up at your eye. " via Slash Gear

Falling Brightness of New TV Models "Displays can be characterized not only by size, but by their typical brightness. TVs have typically required brightness higher than 400 nits, because TV is generally in the living room and watched from a distance. In contrast, brightnesses of less than 300 nits are typically sufficient for IT devices (e.g. notebook PC, monitor, etc.), because these are usually viewed from shorter distances." via DisplaySearch Blog

Sony-Olympus Alliance Aims for High-Tech Surgery "Sony's new alliance with scandal-tarnished Olympus will focus on producing endoscopes and other surgical tools packed with the Japanese electronic maker's three-dimensional imaging and super-clear "4K" display technologies. ...Technology such as 3D and the futuristic displays known as 4K have not yet produced big results in consumer electronics products such as TVs." via Product Design & Development

Sharp's new screens aim to make HD-LCD pixels mobile "The new LCD panel integrates a new pixel design and revamped manufacturing process to achieve the rate of pixels normally reserved for large LCD television screens. According to Sharp, modern CG-Silicon technology allow the screens to display crisper text, super-clear maps and more realistic HD images. ...Sharp produces the 5-inch screen for Apple's recently released iPhone 5." via ZDNet

New glasses free 3D tech could be a game-changer "The company’s CTO, Richard A. Muller, is a professor of physics at the University of California, Berkeley and he created the ‘Soliddd equation” after years of research. ...“We soon discovered the other lenses in the world had been highly inaccurate. Nobody realised just how good autostereo displays can be and so people were not trying to manufacture as accurately as they should be doing.” he told us." via 3D Focus

Fraunhofer HHI Opens 3D Innovation Center "Under the general management of the Fraunhofer Heinrich Hertz Institute, a platform has been created on the salt river in Berlin’s Tiergarten district that brings together some 50 partners from industry and science to drive forward development of 3D technologies and applications. In addition to the fields of entertainment and media, industrial production and medicine will be of key importance for the future." via Display Central

Foxconn ascends, while Sharp struggles "Foxconn is having no trouble drawing new recruits to Zhengzhou, however, and Sharp appears to see little alternative to negotiating with its deep-pocketed Taiwanese rival. ...In its favor, Sharp's in-house technology is highly advanced compared to Foxconn, with the ability to produce items like super-thin touch panels for phones and tablets, highly efficient solar panels, and giant-screen LCD TVs. Still, the future of the Japanese manufacturer may be found in its past." via PC World
