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

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

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

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

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

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

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

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

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

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

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

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

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