Transparent Solar-Cell Screen Charges Phone "Startup Ubiquitous Energy, a spin off from the Massachusetts Institute of Technology, is developing a technology that makes the solar cells themselves transparent by using materials that only absorb infrared and ultraviolet light and let visible light pass through. Researchers at the University of California Los Angeles (UCLA) are taking a similar approach, while researchers at the University of Cambridge are weaving solar cells into organic light emitting diode (OLED) displays, where they can capture light leaked from the edges of the OLED elements as well as from outside the phone." via Discovery News

Society For Information Display Applauds Winners at Display Week 2013 "Display of the Year: Granted to a display with novel and outstanding features such as new physical or chemical effects, or a new addressing method. Gold Award: Sharp and Semiconductor Energy Laboratory (SEL) for Sharp's IGZO LCD (as used in the AQUOS Phone Zeta SH-02E). Silver Award: Shenzhen China Star's 110-inch 4K x 2K 3D TFT-LCD TV" via PRNewswire

Worldwide Microdisplays Market "Microdisplays are small displays that require magnifying optics to use them. These displays are made of a CMOS chip that includes a two dimensional array of transistors. In combination with the liquid crystal material, a cover glass yields a reflective LCD. Microdisplays are generally used in head mounted displays, projectors, view finders, or in other lens view display systems. Continuous and rapid development in display technology has made the way for different types of displays in the commercial market in the past few years." via SBWire

Amazon Acquires Display Maker Liquavista "Liquavista uses a technology called electrowetting to develop color displays for e-readers and portable media players. The first commercially available electrowetting display panels are expected to arrive this year, according to the Digital Reader. ...Electrowetting produces displays with advantages in a couple of key areas—viewability in various lighting conditions and low-power video playback. Amazon, a leading maker of both ereaders and tablets, may be interested in Liquavista's technology for both device categories." via PCMag

New Quantum Dots Make Colors in LCD Even Brighter "In work that appears to tip the scales further for quantum dot-enabled LCDs, researchers at the University of Illinois at Chicago (UIC) have developed a method for doping quantum dots that will give LCDs a color vibrancy not seen before. In research published in the ACS journal Nano Letters ("Cluster-Seeded Synthesis of Doped CdSe:Cu4 Quantum Dots"), the UIC team reveal a method for introducing precisely four copper ions into each and every quantum dot. This doping with copper ions opens up the potential for fine-tuning the optical properties of the quantum dots and producing extraordinarily bright colors." via IEEE Spectrum

Japan Display expands manufacturing "Japan Display President Shuichi Otsuka announced yesterday that the company is boosting capacity of high-definition LCD manufacturing at its plant in Chiba as it has set its target sales this year at 800 billion yen (7.8 billion US dollars), almost double the 450 billion yen it earned last fiscal year. “Our business is now on track,” said Otsuka, who previously was CEO at Elpida Memory Inc. “Our technology is unique, so it won’t be easy for other companies to do the same.” By competitors, Otsuka means companies like Sharp Corp. also from Japan, South Korea’s LG Electronics and Samsung Electronics Co. and Taiwan’s Innolux Corp., also big names in the display-making industry and sharing the market with Japan Display. Japan Display’s share of the global market for small- and mid-sized LCDs was 16.6 percent in 2012, Sharp Corp. held 14.8 percent, followed by LG Display Co.’s 13.5 percent and Innolux’s 10.2 percent." via Japan Daily Press

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

Displays market loves LED lighting "In conclusion, the benefits of using LED lighting in an automotive environment has several positive implications. First, they never need to be replaced, since their solid state longetivity is in excess of 100K hours – equivalent to 11.5 service years, thereby surpassing the life of the vehicle. This allows automobile manufactures to permanently embed them into “in cabin” backlighting without requiring accessibility for replacement. Styling can also be dramatically altered as LED lighting systems do not require the depth or area as do CCFL bulbs." via Electronics Weekly

Glasses-free 3D display for theaters "It is not surprising that almost every movie is now produced in 3D. An additional incidental benefit is a reduction in illegal in-theater recording of movies. However, there are several reasons why some people are against 3D movies, in particular the discomfort of wearing special glasses. Yet, even though glasses-free 3D display technology has been commercialized for personal devices, such as the Nintendo 3DS, significant limitations must still be overcome for theater-scale projection. For glasses-free display, special optical parts must be installed in front of the screen, which interrupts original images from a projector and is incompatible with conventional theaters. ...To meet this demand, we have developed a glasses-free, front-projection 3D theater display system.2" via SPIE

Application scenarios for interactive OLED data-eyeglasses "The interdisciplinary project FAIR is funded by the Federal Ministry of Education and Research (BMBF). It is dedicated specifically to the support of physical functions by using “hand-free applications in augmented reality“ (FAIR). Within this joint-project demonstrators for innovative human-machine-interactions will be developed. A display – similar to eyeglasses – represents the visionary interface. The control and interaction with the display will be achieved via eye movements. Thus the displayed elements can be seen but provide at the same time the possibility for interaction. This enables the user to start different computer-controlled actions via eye movements. The first steps within FAIR will focus on three special application scenarios: assistance and interaction systems for persons with disabilities, innovative human-machine-interfaces in the field of entertainment as well as information- and augmented-reality-interfaces in industrial maintenance scenarios." via nanowerk

Researchers turn regular LCDs into touchscreen "Doctoral students Ke-yu Chen and Sidhant Gupta work in the Ubiquitous Computing Lab on campus. They came up with the idea for their project, uTouch, while working on a similar project called LightWave that tested how the energy given off by any electronic devices in someone’s house and even by the human body can be manipulated to control an electronic device. The energy, called electromagnetic interference (EMI), is what caused a light bulb to dim and brighten as they moved their hands closer and farther away from the bulb. “We thought that the monitor could have a similar effect,” Chen said. It did. Chen said an LCD monitor radiates EMI, also called noise, to the power line when it is turned on. The EMI increases as the human hand approaches the screen, and uTouch captures the EMI variations and uses them as signals to detect a touch gesture." via The UW Daily

Is touch really the future of the PC? "Right now the best touch pads have an accuracy of 1mm the best touch screens have an accuracy of 7mm. Right off the bat we can see that a touch screen is 7-times less accurate than a touch pad. But there is more to it. When you use a touch pad your eyes are on the object you want to manipulate on the screen while your finger is on the pad. When you use a touch screen your finger is on the screen often blocking the item you want to manipulate. Now consider that the average finger is about 10mm across. You are now blocking the area you want to work on with your finger, which is larger than the sensor in tour touch screen." via Decrypted Tech

Scientists Discovered a New Less Expensive Technique of Creating 3D Images "Scientists at University of Glasgow's School of Physics and Astronomy discovered a new less expensive technique of creating 3D images. They created a system which makes use of the detectors that have single pixel for sensing the light instead of various pixels used in imaging sensors found in digital cameras. The detectors have the capability of judging the frequencies beyond visible light, which in turn would help in various new applications for 3D imaging in geography and medicine. The scientists explained that the single pixel detectors will cost just a few pounds in comparison to present systems which amount to thousands of pounds. " via Jagran Josh

Say Goodbye to the Sharp that We Knew "If we look at the difference between consolidated LCD sales and gross LCD sales before eliminating internal transfers, we see that only 50% to 60% of sales were external transactions in 2008–2012. The portion of external sales increased in FY2013 but the LCD assets in Sakai were removed from consolidation as part of Sharp’s effort to lighten its balance sheet in September of 2012. That means sales from Sakai’s Gen-10 lines no longer contribute to operating results. The problem with that is Sharp’s own capacity becomes only 3% of the industry and that share is declining. Sharp is already smaller than China Star (CSOT) on a consolidated business basis. Thus, Sharp has few alternatives to becoming more of a merchant supplier to other brands, like Samsung." via Display Central

Europe honours LCD screen pioneer Martin Schadt "In 1970 the Swiss physicist achieved a breakthrough that would pave the way for LCD read-outs at first on calculators, watches and alarm clocks, and then flat-panel TVs, laptops and smartphones. But one year later his employer, Roche, thought the feat was a mismatch with its other pharmaceutical-focused efforts and canned the project. Thankfully, the decision proved short-lived and Dr Schadt helped the firm become a major supplier to the screen-making industry, as well as making further contributions to the technology's evolution. His admirers know him as the "father of the pixel", and this week the European Patent Office gave him its lifetime achievement award, noting that sales of devices featuring LCD panels totalled $120bn (£80bn) in 2012." via BBC News

Use of quantum dots with LCD screens in consumer devices edging closer to reality "Quantum dots are very small bits of semiconducting nano-crystals—they're useful because they can be confined in three spatial dimensions allowing for very tight control of emitted light at precise wavelengths. Shining a light through them produces exceptionally pure colors—applying trillions of them to a thin film allows for the display of color richness never before seen with LCD devices. Researchers have been raving about the benefits of the technology for several years while manufactures have been promising that devices with the technology would soon become available to consumers. It appears that such promises are finally about to come to fruition." via Phys.org

Apple going back to Samsung as LCD panel supplier "The industry believes that one of the reasons Apple has decided to come back to Samsung Display is because of its ability to get its hands on thin glass. Thin glass is a major component used in LCD displays that can be found in mobile devices—Apple uses them in its iPhones and iPads." via iDownloadBlog

Europe's largest liquid crystal display factory opened in Ventspils, Latvia "In its new plant in Ventspils Ltd. "EUROLCDS” will produce different types of passive liquid crystal display technology based products. The goal of the company is the global market (Europe and the USA), but primarily the European cluster of LCD products. Liquid crystal display materials will be supplied mainly from China and Japan. One of the largest business segments of the factory will be production of glass that automatically darkens when exposed to bright light for welding masks. Road signs and information display products that use EASL Polydisplay technology will also be produced. At present, the company employs 20 employees, but with the business growing, the number of employees is expected to increase up to 50; in the future there might be 50 more employees employed in distribution and administrative proceedings." via Ventspils.lv

Transparent graphene-based display could enable contact lens computers "The researchers were able to build miniature inorganic LEDs by connecting the graphene sheets together with silver nanowires into a hybrid structure. The flexible silver nanowires enabled the hybrid strucuture to maintain its high conductivity even when bent. The most important factor for using the hybrid graphene in a contact lens-based computer is its high transparency. Other transparent materials like indium tine oxide (ITO) become much less conductive when bent. When the hybrid LEDs were embedded into a regular soft contact and tested in a rabbit no ill effects were observed." via ExtremeTech

Government aid helped make Sharp's IGZO crystals a reality "To develop IGZO, Hosono received research funding from the Japan Science and Technology Agency (JST), an independent administrative agency affiliated with the science ministry. The agency provided 1.8 billion yen ($18 million) of funding for a five-year period beginning in 1999. Of that, around 100 million yen was used for basic research on IGZO. IGZO is dozens of times more conductive than silicon. It can make smaller TFTs and give high-definition quality to liquid crystals." via The Asahi Shimbun

The Future of 3D TV and Why ESPN Dropped Its Pioneering 3D Channel ""3D does cause people to switch off in its present form,” admitted Andy Quested, BBC’s head of 3D and HD. “About 20 percent of people find sports matches in 3D simply too long. Twenty-five percent of people are apathetic toward 3D viewing no matter the content. Another 10 percent can’t see 3D because of visual impairments, but arguably up to half the audience for 3D content is put off by having to wear glasses." Dolby is among the stakeholders arguing that glasses simply won’t work in the home." via The Hollywood Reporter

Innolux sales drop after ceasing touch display operations "In a statement issued on Friday, Innolux reported consolidated sales of NT$37.47 billion (US$1.25 billion) last month, down 8.4 percent from a month earlier and also down 5.2 percent from a year earlier. At an investor conference on May 9, Innolux said the termination of its touch display enhancement technology operations would cut its sales by about NT$5 billion during April and last month, but its gross margin would improve accordingly." via Taipei Times

Hon Hai Annoints Display Research Center In Japan "Hon Hai Precision Industry announced that it has established a research and development center in Japan to focus on display screens and touch panels. As a part of its diversification strategy, Hon Hai is reportedly expanding its businesses outside the OEM sector. The company has continued to invest in the display screen sector; in 2012, Hon Hai acquired a 38% stake in Sharp's Sakai TV panel factory." via China Tech News

New tactile display sends information through skin instead of eyes "Your sense of touch could be the next frontier in relaying valuable contextual information if new research currently being conducted at MIT proves successful. Researchers believe it may be possible to design wearable arrays of GPS-enabled vibration motors that provide simple navigational cues or detailed data through a kind of tactile Morse code. This could lead to non-visual haptic display technology — why not check your email without even opening your eyes?" via ExtremeTech

New Technology Creates Unbreakable Smartphone Display "The plastic substrate created by Professor Yoon and his research team have greatly enhanced needed properties of heat resistance, transparency, flexibility, inner chemical capability, and tensile strength. Although the material retains flexibility as a native advantage of plastic film, its tensile strength is three times greater than that of normal glass, which is a degree similar to tempered glass. In addition, Professor Yoon’s substrate is as colorless and transparent as glass and resists heat up to 450℃, while its thermal expansivity is only 10% to 20% of existing plastics." via PCB 007

How supersensitive screens get touch-y "Have you seen a diagram of a mobile phone display? It's a lot more than the cover glass you're worried about shattering when you drop your phone. There are layers that stack up to form the whole package, from the coated cover glass on top through filters, substrate glass, and screen material, like the LCD or OLED sheaves that actually turn pixels on and off to create the picture you see on the screen." via CNET

A Pleasure To Touch: Advanced Human Machine Interface Touchscreens For Vending "Engineers need to consider three key factors when looking to embed touch control into vending machines. 1. The specified touchscreen solution must be durable, as these pieces of equipment are designed for 24/7 public use. Furthermore, some venders may be deployed in a variety of environments, including outdoors, where they will be subjected to wind, moisture and extreme temperatures. As the machines may be located in lightly supervised areas, the chosen touchscreen should be resistant to deliberate harm from vandalism, in addition to accidental scratches from users' watches and jewelry." via Vending Times

Wearable Computing Pioneer Says Google Glass Offers “Killer Existence” " [Another] thing is that we’re going to see these interfaces that augment the user’s eyes, ears, and mind in such a way that it actually helps with their daily life instead of distracts them. Suppose you’re playing a video game or watching TV. Having something that actually shows you the TV guide or a second screen while you’re doing other things is really powerful." via MIT Technology Review

Developing 3D gesture-based car dashboards "One common aspect of the systems now emerging is that the touch screen head unit represents the nexus of an ever-growing diversity of input signals such as television and DVD, live video and graphics from advanced driver assistance systems, status information from various vehicle sensors, Bluetooth communications, GPS and mapping, and Internet content such as traffic updates, news feeds and social media notifications. User interface design is critical if drivers are to gain the maximum benefit from interacting with the system without suffering distractions or information overload. Considerations for designers extend beyond the layout and menu structure to encompass multiple ways of interacting with the system; touch, gesture and voice control will all be necessary, in addition to control using buttons on the console and steering wheel." via ElectronicsWeekly

An elastic touchscreen into which you can literally sink your fingers "The stretchable touchscreen, dubbed Obake, was created by Dhairya Dand and Rob Hemsley, both of MIT’s Media Lab. The touchscreen basically amounts to an interactive display on top of an elastic surface. When you poke or pull at the display, depth cameras measure your movements and tell linear actuators to manipulate the elastic surface accordingly. So, if you make a pinch-and-pull motion, the depth cameras will measure it, then the linear actuators will make elastic stretch and protrude in such a way as if you’re pulling it. The surface doesn’t just create little mountains of stretched elastic; it can also create resistance if you, for example, push inward rather than pull outward." via ExtremeTech

The American Display Company That Samsung Relies On For Success "When the S4 launches this month it will have a new generation of clarity in the display, one that iPhone lovers might envy. It will be thinner. And the battery life will be extended by about 20%, even with the high definition screen. It’s about to become a better phone. The reason for this is US technology. At least that is one important reason. Technology that gives the Galaxy S4 a better screen but also longer battery life and the thinner form factor. Samsung’s Galaxy S4 relies on materials and patents from New Jersey-based Universal Display Corporation. Without Universal there would be no efficient, thin, beautiful OLED display for the S4. But Universal’s relationship with Samsung goes back through the whole Galaxy line. And it stretches far into the future." via Forbes

High-tech specs: Electronic eyeglasses offer wearers more control ""It totally removes the corridor of traditional progressive lenses," he said. "So it makes your reading seem like you're reading through single vision lenses. [It's the] same with the computer use, so instead of relying on a little corridor and adjusting your head, you can use the whole lens to see distance, intermediate and up close, so it really enhances the comfort." ...He compared the technology of the touch sensor to that of a smart phone. The eyeglasses have "a microchip, composite lenses with a thin transparent LCD-like layer, miniature rechargeable batteries and a micro-machine accelerometer to detect tilt," according to a press release. "The microchip, micro-accelerometer and miniature batteries are hidden inside the [eyeglass frame]. The transparent liquid crystal layer in each lens is able to electronically activate the reading portion when the wearer needs it."" via The Altoona Mirror

World's first smartphone for the blind "The smartphone uses Shape Memory Alloy technology, based on the concept that metals remember their original shapes, i.e. expand and contract to its original shape after use. The phone's 'screen' has a grid of pins, which move up and down as per requirement. The grid has a Braille display, where pins come up to represent a character or letter. This screen will be capable of elevating and depressing the contents to form patterns in Braille." via The Times of India

This Bobbing Display Lets You Read While Running On A Treadmill "Instead of simply enlarging the text to make it easier to read or relying on oversized monitors, ReadingMate allows a treadmill user to read normal-size text on a small monitor mounted in front of the machine. The system relies on infrared lights embedded in special goggles that are tracked by an infrared camera positioned in front of the runner. As the user’s head moves vertically, the system moves the text accordingly. ...In addition to letting treadmill users catch up on some reading while burning some calories, the researchers say ReadingMate could also find aviation, construction and transportation applications. Not to allow drivers and pilots to enjoy a good book while on the job, but to stabilize information displayed on screen while experiencing heavy shaking or turbulence." via Gizmag

A Simple Way to Turn Any LCD into a Touch Screen "A group of researchers from the University of Washington’s Ubiquitous Computing Lab developed a method called uTouch that uses a simple sensor and software to turn an ordinary LCD into a touch screen display. The system takes advantage of the low levels of electromagnetic interference produced by many consumer electronics, harnessing it to do things like control video playback with pokes and motions on an otherwise noninteractive screen. “All these devices around you have all these signals coming out of them, and we ignore them because we think they’re noise,” says Sidhant Gupta, a PhD candidate at the University of Washington’s Ubiquitous Computing Lab and one of the co-authors of the paper." via MIT Technology Review

Are touchscreens right for all equipment? "“With touch, you lose tactile feedback. With traditional controls a person using the instrument can continue to use the equipment without having to stare at it,” says Siegel. This is true of much research equipment, which requires simultaneous fine-tuning of several pieces of equipment at once. Sometimes functions available in one section of an application on a touchscreen are difficult to access from another section. This could be one reason TI has not seen a widespread adoption of touchscreen technology in the scientific research space. Siegel speculates that the consumer market usually sets the trend, and popular capacitive touchscreens are general overkill for research instruments." via R&D Magazine

U.S. Seeks Voluntary Limits On Car Touchscreens "The new guidelines limit simple tasks to two seconds. They also restrict the time allowed for complex tasks to 12 seconds, but do not limit the number of times a driver can touch a screen. The decision on whether a screen would freeze or shut down after 12 seconds would be left to automakers based on their own research, NHTSA said. The auto industry’s current guidelines, which are a decade old, allow drivers to read text and perform other more complex tasks while cars are moving at less than 5 mph, Strickland said. Systems now are designed so multiple-step tasks take 10 or fewer screen touches for a total of 20 seconds with a driver’s eyes off the road. But the devices won’t turn off or stop a driver from doing something that takes longer than 20 seconds." via CBS DFW

Prototype could revive glasses-free 3D displays "Dolby says they have now developed a system that encodes a 3D image stream and can decode it in real time to produce 3D without the need for glasses on "any 3D TV, tablet, laptop or smartphone" with sufficient resolution. The design requires adding a sheet of plastic with undulations that deflect light at 26 different angles simultaneously, offering effective 3D views from a wide range of angles. Because resolution is lost as an image is split and sent in different directions, the underlying display must be four times the resolution of HD television. Such displays are expensive, but they are becoming available, so 3D may yet have a future." via New Scientist

Why Don't We Have Holodecks? "Researchers at the University of Illinois at Chicago recently created Cave2, the highest-resolution immersive panel display in existence. The cave is made up of 72 3D LCD panels arranged in a 320-degree shape. A special pair of glasses with tracking dots on them helps the computer know in which direction you're looking so it can adjust the images to fit your perspective. You can also use a wand, covered with sensors, to interact with the 3D objects around you. For now, the system is used for high-resolution medical-image viewing. It's cool but probably won't be in your living room anytime soon. What about recreational holodecks? Nathan Burba, director of Project Holodeck (which is exactly what it sounds like), told PM that cost has been a big issue until recently. "I would say that the technology has obviously been limited," he says. "The display technology has been locked away in military research, and there's a lack of innovation there because of the stringent requirements put on researchers."via Popular Mechanics

Google Glass is finally here: Tech specs released, first units shipped "According to the spec sheet, Google Glass will offer one full day of battery life for normal usage, but features like Hangouts and video recording will expend the battery faster. Google recommends recharging the kit with with the Micro USB cable and charger it supplies with Glass. The display resolution is the "equivalent of a 25-inch high definition screen from eight feet away", but Google is being no more specific than that. " via ZDNet

LG Rolling Out Curved OLED TVs in South Korean Market "Why curved? The idea is to offer to an IMAX-like experience in the home. A curved display also eliminates the problem of screen-edge visual distortion and loss of detail since the entire surface is equidistant from the viewer's eyes, LG says. The curved TV itself is just 4.3 millimeters (0.17 inches) thin and weighs 37.48 pounds. It uses proprietary WRGB technology and a four-color pixel system that features a white-sub pixel in addition to red, blue, and green." via HotHardware

Japan Display turns to smaller smartphone makers "Japan Display, the world's No.1 maker of small to mid-size panels, may increase sales to as much as 800 billion yen ($8.10 billion) for the fiscal year ending March 2014 from slightly below 500 billion yen a year earlier, said Shuichi Otsuka, CEO of the unlisted firm. The company, formed out of a merger of the small panel divisions of Sony Corp, Hitachi Ltd and Toshiba Corp last April, does not publicly identify its clients but is widely known as a key Apple supplier. Apple undershot Wall Street's sales forecast for the third straight quarter in the three months ended December after iPhone sales missed expectations." via Yahoo! News

Future of Computer Human Interaction on display at Paris conference "The future of computing comes to Paris this week with the annual Computer Human Interaction (CHI) conference, which showcases new approaches to the way users connect with electronics. ...One of the big draws at the conference is the “interactivity” section, which is like a mini trade show of futuristic prototypes that attendees can try out for themselves. Gone are the days of just keyboards and mice. “We’re seeing things that go much further into the future,” Baudisch said." via PCWorld

How today’s touchscreen tech put the world at our fingertips "Because it's so different from mouse-and-keyboard-driven and stylus-driven software, touch-driven software has also transformed the hardware it runs on. Most smartphones include just a few physical buttons: power, volume, a mute switch, and the home button. Using a touchscreen as the primary input obviated the need for things like a hardware number pad or keyboard, since the screen could dynamically become whatever it needed to be. Software keyboards have become even more context-sensitive over time, adding things like a ".com" button when typing in a URL field." via Ars Technica

Aggressively combat noise in capacitive touch applications "Today, thin is in. The push to make aggressively thin form factors for touchscreen devices, especially mobile phones, creates a two-fold problem: more noise coupled into the sensor from the display and a higher parasitic capacitance of the sensor. Displays generate noise that is much lower amplitude when compared with charger noise, but they can have a huge impact on touch performance due to their close proximity to the touch sensor. While AMOLED displays are very quiet (but more expensive than LCDs), the majority of the market today is still the noisier ACVCOM and DCVCOM-type LCD displays. It is the VCOM layer, the common electrode, of these displays that is the source of their noise." via EDN

Fujitsu Laboratories New Touch-based Interface Marries Analog & Digital "Transform boring, poorly stapled business plans, press releases, marketing materials and other old fashioned paper artifacts to life using Fujitsu Laboratories’ touchscreen interface that can animate and bring a whole new dimension to real world objects. ...This amazing touchscreen interface is also non-biased and can adjust color and brightness, and skin color accordingly so that it isn’t influenced by external or environment circumstances. In addition, if you don’t want to operate the device by touch alone, you can also manipulate the sensors with gesture controls — you can explore three dimensional objects with the simple movement of your fist to get a full 360-degree view." via Gadizmo

Samsung Demos a Tablet Controlled by Your Brain "The concept of a dry EEG is not new, and it can carry the drawback of lower signal quality, but Jafari says his group is improving the system’s processing of brain signals. Ultimately, if reliable EEG contacts were convenient to use and slimmed down, a brain-controlled device could look like “a cap that people wear all day long,” says Jafari." via MIT Technology Review

Advances in capacitive touchscreen for mobiles "First, it is critical for designers to understand the underlying construction of a touchscreen system to be able to understand how technology changes are remaking this segment. The key components in a touch system include the coverlens, sensor, LCD, and PCB. The coverlens is the outward facing component of the product. This is where the consumer interacts with the screen. In some products, this coverlens could simply be a protective cover to prevent scratching and damage, or it can actually be part of the touch sensing system itself." via EET Asia

'Interactive Fish Tank' turns water into a capacitive touchscreen "Once it makes contact with the surface, Donoso explains, a finger "acts in the same way as touching a button on an iPhone or any other touch screen." Indeed, in substituting glass for water, Donoso and Moore present a different, and perhaps more accessible way to understand how capacitive touch works on traditional displays. The underlying principle is the same: a user's touch elicits some change in the surface at the point of contact, and the software reacts accordingly. Whereas smartphone displays gauge this change in terms of electric charge, "Fish Tank" measures it in ripples." via The Verge

Discomfort and fatigue from stereo 3D displays "In stereoscopic displays, images have varying binocular disparity thereby stimulating changes in vergence as happens in natural viewing. But the accommodative distance remains fixed at the display distance, so the natural correlation between vergence and accommodative distance is disrupted, leading to the so-called vergence–accommodation conflict. The conflict causes several problems. First, differing disparity and focus information cause perceptual distortions. Second, viewers experience difficulties in simultaneously fusing and focusing a stimulus. Finally, attempting to adjust vergence and accommodation separately causes visual discomfort and fatigue in viewers." via SPIE

Shapeshifters: phones of the future could morph on demand "The six working prototypes, known as "Morphees," are thin, electronic displays capable of automatically changing shape to perform certain functions. Researchers say that if brought to market, the devices could usher in a new era in mobile computing, breaking down the physical barriers that have traditionally defined smartphones, tablets, and gaming consoles." via The Verge

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

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

Growth slowing for TFT LCD glass substrate capacity ""With TFT LCD business maturing and growth slowing, leading manufacturers have begun to mitigate their business risk by converting production from TFT LCD glass to aluminosilicate glass," according to Tadashi Uno, director of materials and components market research at DisplaySearch.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Amazon, Barnes and Noble, Kobo, Bookeen, and Bebook all use e-Paper made by e-Ink Holdings. This company has had a stranglehold on the entire e-reader segment. With the industry gravitating towards illuminated screens and e-Ink Triton 2, there aren’t any takers for LG." via Good Ereader

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

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

Firewall: A Depth Sensitive Interactive Wall "Firewall is an interactive installation, a seemingly normal wall that is actually a stretched spandex surface which acts as a membrane interface sensitive to depth.

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

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

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

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

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

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

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

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

New E-Reader Display Aims at Video and Color "Of course, the liquid crystal displays on tablets already show color, but they do so by shining colored lights out of the screen. E-readers, on the other hand, create colors by reflecting incoming light. They use much less power, are easier to read in sunlight and are thinner than LCDs." via Live Science

LCDs, Aperture Ratios, and Hummingbirds "The area ratio of the opaque transistor and the transparent electrode is a key metric called the aperture ratio. So let’s make the transistors smaller. Obvious, right? Easier said than done." via Applied Materials

LTPS AMOLED is Coming on Gen 8 "In the production tool, the laser beam is optically broadened to a line that can be as large as 1300mm, and is swept along the substrate in the long direction (see figure). The 55-inch displays are produced 6-up in a 3×2 matrix. The line beam makes one pass from the top and one from the bottom, so the sweep edge does not cross any display and stitching in not needed." via Display Central

Applied Materials unveils new PVD, PECVD tools for display manufacturing "The Applied AKT-PiVot PVD for metal oxide-based thin-film transistors (TFTs) enables a transition from aluminum to copper interconnect bus lines leading to faster pixel response and lower power consumption in LCD TV panels. It overcomes the problem of "mura effect" that reduce display quality, which the company says has hindered metal-oxide technology's inroads into mainstream LCDs. The "breakthrough" stability of the IGZO films deposited by the tool offers the promise of metal oxide backplanes for OLEDs which would significantly lower their cost as well, the company adds." via Solid State Technology

Why bigger is better for FPD recovery and growth "“The average diagonal sizes of key FPD applications have increased over the past three years, and every inch of growth in flat panel display applications results in growth in area demand and thus capacity utilization,” points out David Hsieh, VP of Greater China Market Research for NPD DisplaySearch. Consumers won't want to go back to smaller displays and lower resolutions, so average (diagonal) sizes will accelerate in 2013, spurring long-term growth for the entire flat-panel display industry." via Solid State Technology

Research to expedite LCD monitor recycling "Recycling LCDs currently entails a high labour cost because mercury in the back of LCDs requires proper disposal. Without recycling, LCDs are incinerated using expensive emission control equipment or are discarded in landfills where their potentially hazardous materials may contaminate the soil and water. The units also contain gold and indium tin oxide, which are valuable and scarce resources but are difficult to extract. The project is funded by a US$ 15 000 grant from the US Environmental Protection Agency’s P3 project." via Recycling International

Patent Issued for LCD Panel Having Improved Response ""The present disclosure relates to reducing response time, decreasing driving voltage and/or increasing transmittance of an LCD. In accordance with the present disclosure, the LCD may include a liquid crystal layer having liquid crystal molecules. A chiral dopant may be dispersed within the liquid crystal layer and configured to bias the liquid crystal molecules toward a twisted state that facilitates light passage through the LCD. Such a configuration may reduce response time and/or decrease driving voltage. ..." via Equities.com

iTomb design offers mourners touchscreen tributes from the grave "The iPad – inlaid into a stone slab – is powered using solar energy and comes with a protective cover to ward off the elements and theft." via Macworld

Sharp is on the verge of collapse, IGZO technology remains only hope for survival "It was not, however, the smartphone venture that caused so much trouble; it was the company’s overzealous turn to produce LCD panels for large TV screens. As part of the company’s restructuring plan, it will turn its focus on the booming smartphone and tablet market and product small- to medium-sized LCD panels keeping IGZO (named after indium gallium zinc oxide semiconductor) technology aboard. IGZO is believed to be a power-saver but what if other companies, like LG and Japan Display, could develop a display technology better than what Sharp offers?" via The Droid Guy

Electrofluidic imaging e-paper has no pixel borders "In current electrowetting displays (devices that use electricity to move pigmented fluids around), colors maintain their image-forming distinctiveness via pixel borders that ensure that the pixel's color does not bleed over into the next pixel or color. This matters because pixel borders are dead areas that dull any display of information, whether a display of text or image. Leading electronics companies have been seeking ways to reduce or eliminate pixel borders to increase display brightness." via Laser Focus World

New Ideas in Digital Signage "The visceral adoption of tap, swipe, and zoom interactivity has set the stage for how people will interact with digital signs. Beyond simple touch interaction, scan, RFID, and NFC will deliver personalized information to displays and even grant or deny entry access to users interacting with electronic room signs." via AV Network

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

Hand-waving can decode invisible images on screen "The system, developed by Hirotsugu Yamamoto and colleagues from University of Tokushima in Japan, uses a newly developed LED panel that can display 480 images per second. In this video, a pair of images of the New Scientist logo (one black, one white) is embedded into the background. When displayed alternately at a high speed, they are invisible to the naked eye. "A hidden image is presented 10 times faster than the frame rate used at the cinema," says Yamamoto." via New Scientist

Continuing to deliver improved performance challenges traditional display manufacturing techniques " The type of transistors and the processes used for their manufacturing determine the performance of the display, the costs, and, to a large extent, the environmental footprint of the device. Today, two transistor types are common in mass production; amorphous silicon (a-Si) transistors are dominant (>95%), while low temperature polysilicon transistors (LTPS) have a niche position." via Solid State Technology

Digging for rare earths: The mines where iPhones are born "Inside the rocks from this mine are rare-earth minerals, crucial ingredients for iPhones, as well as wind turbines, hybrid cars, and night-vision goggles. Minerals such as neodymium are used in magnets that make speakers vibrate to create sound. Europium is a phosphor that creates a bright red on an iPhone screen. Cerium gets put into a solvent that workers use to polish devices as they move along the assembly line." via CNET

AUO to adopt printing process for producing AMOLED panels "Taiwan-based TFT-LCD panel maker AU Optronics (AUO) hopes to increase its AMOLED material usage to 70-80% by using printing processing, which is expected to be the mainstream for producing large-size AMOLED panels in the future, according to industry sources." via DigiTimes

The iPhone 5 Display: Thoroughly Analyzed "While many were hoping for a move to OLED or some other screen innovation, this really is a huge step up that is very easy to quantify. To put this in perspective, in the past few years I've reviewed probably 30-40 different displays, from PC monitors to TVs to projectors. Not a single one, out of the box, can put up the Gretag Macbeth dE numbers that the iPhone can, and perhaps one projector (which listed for $20,000) can approach the grayscale and color accuracy out of the box." via AnandTech

Why the iPhone 5 doesn't have an AMOLED screen "As well as the iPhone 5 being too big a product launch for AMOLED to grace, there's also the small matter of the supply being dominated by Samsung Display, which makes over 90% of AMOLED screens. "Now Apple and Samsung are engaged in intense legal battles," says Werner, "it is unlikely that Apple would want its arch-rival to also be its single source for OLED displays."" via Tech Radar

Cephalopods may be the key to better e-paper screens "When the creature needs to be a little lighter in color, muscle fibers pull the cell membrane outward, reducing the density of the pigment. These fibers relax when a darker color is needed. E-paper screens like the one used on the Kindle use a similar technique with light and dark pigment capsules embedded in each pixel." via Geek.com

HDTV Expert - No OLED-TV Panel Production from LGD until 2013 " The best bet for LGD’s delay is still the oxide backplane. Oxide remains the most promising next-generation semiconductor material for thin-film transistors (TFTs), and Sharp has apparently gotten it to work for LCDs in volume production. But oxide researchers overwhelmingly say there are a few remaining stability issues, at least when oxide TFTs are used with OLEDs, that will take another year or so to resolve." via HDTV Magazine
