Winner of the Prize for Best exhibitor at the I-Zone startups and New Tech Demos area at the SID Display Week 2017, Hella together with students from the Institute for Large Area Microelectronics at the University of Stuttgart demonstrate their project to Develop an Active Matrix LCD for Use in High Resolution Adaptive Headlights also presented in detail in this paper.
Conventional adaptive driving beam headlamps are limited in achieving still higher quantities of switchable pixels by the number of LEDs and movable elements needed. In this paper, it is shown that by integrating an active matrix liquid crystal display module, it is possible to realize fully adaptive high-resolution headlights without mechanical elements and a finite number of LED with 30 k switchable pixels.
As adaptive driving beam headlamps (ADBs) are now established and already available in mass-production vehicles, the market is requesting headlight systems with increasing resolution.
State of the art are LED matrix modules such as the HD84 from Hella KGaA Hueck & Co. that realize low beam, ADB, and additional functionalities by using 84 switchable LEDs. But the number of pixels that can be realized using this approach is limited by the number of LEDs that can be integrated in the tight installation space of a headlamp.
Higher resolution is needed to be able to implement new lighting functions to further improve traffic safety when driving at night or dusk. To realize a significant increase in traffic safety, the ADB must be able to simultaneously fade out several drivers of traffic oncoming of the vehicle to avoid glaring and to highlight important areas like road markings and traffic signs. To accomplish this, the headlamp must be able to divide the illuminated area in front of the vehicle into a grid of small areas with individually controlled light intensity. The higher the resolution of the grid, the better are the realizable lighting functions.

Super Image projection technologies glowfilm is a technology that enables any piece of glass to be a transparent digital display. The technology uses a transparent emissive film that can be applied to any piece of glass. For example, car Windows be turned into displays using this technology. It can also turn home windows into displays for decoration. The technology can even be used to manufacture televisions by using projectors and glass.

Dr. Frederic J. Kahn is an early pioneer in Liquid Crystal Displays, He developed some of the original LCD technology for Hewlett Packard calculators. Currently President of Kahn International, he recognized early on the unique physical properties of liquid crystals and their applicability to a broad range of direct-view (flat-panel) and projection displays, as well as to related printing and electronic component manufacturing systems. He has consistently and successfully followed up and built upon that vision with major contributions to the development of commercial enterprises based on information-display technologies.
At the NEC Central Research Laboratory in Kawasaki, Japan, from 1968 to 1969, he proposed and initiated NEC's liquid-crystal-display R&D, including invention of a field-effect color-change LCD. Starting in 1970, at Bell Telephone Laboratories in Murray Hill, New Jersey, he initiated Bell Labs' LCD R&D; advanced the understanding and control of LC molecular alignment on solid substrates; invented and was the first to publicly disclose (June 30, 1971) a vertically aligned nematic (VAN) LCD that reorients in a preferred direction at low voltage and which, after three decades of additional development and invention by subsequent workers, is now used in most flat-panel LCD TVs and high-performance LCD projectors; and invented and developed high-resolution LCD projection imaging devices and systems based on laser-addressed smectic-A LCDs.
While Kahn was a project manager for liquid-crystal displays at Hewlett-Packard Laboratories in Palo Alto, California, he led the development of multiplexed TN-LCD technology, which led to HP's first LCD calculator products, including the best-selling HP 12c business calculator, introduced in 1981 and still sold today (2010). He also developed 40-character multiplexed dot-matrix alpha-numeric LCDs for portable computers and a computer-interactive high-resolution C-sized engineering drawing display. As department manager for optical materials and polymers and later for storage physics, he also led optical-fiber, IC-lithography, and erasable-optical-memory programs.
Kahn founded Greyhawk Systems in Milpitas, California, in 1984 and served as VP Technology, with operational responsibility for LC light-valve development and manufacturing, as well as for new systems and applications development based on IR laser-addressed smectic-A and real-time photo-addressed (CRT and active-matrix) a-Si LCD projection technology. Greyhawk's products included 7.5-Mpixel 40-in. D and 37.5-Mpixel 144-in. D full-color displays (Softplot and LAD, respectively), an 8.4-Mpixel professional short-run color printer (Ilford Digital Photo Imager), and a 31.5-Mpixel printed-circuit-board exposure and development system (DuPont Seriflash).
According to Dr. S. T. Wu at the College of Optics and Photonics at the University of Central Florida, "Dr. Kahn has made significant scientific and technological contributions in liquid-crystal alignment, especially single-domain vertical alignment, which laid down the foundation for today's liquid-crystal–on–silicon projectors (commercialized by Sony and JVC), thermally addressed electrically erased high-resolution smectic liquid-crystal light valves, and pitch dilation of cholesteric liquid crystals, just to name a few."
Dr. Kahn has 18 issued U.S. patents and is the author or editor of over 40 technical publications. He has been a Fellow of SID since 1981. In 2011 he received the Karl Ferdinand Braun Prize, the highest honor of the Society for Information Display (SID) for his "contributions to the research, development and commercialization of liquid crystal displays."
He has been General Chairman or Program Chairman of six international display conferences sponsored by SID, SPIE, and/or IEEE. He has also served as an SID International Officer (Secretary) and is currently a member of the SID Display Industry Awards Committee and the SID Display Week Program Committee. His current work includes intellectual property and high leverage consulting activities.

Acer presents their new 4K DLP projectors at 2499€ and 2999€ (MSRP, price may vary by location). Bringing 4K projectors closer to being affordable by a larger market. Here we try to look at the 4K quality. Acer V7850 (2999€ MSRP) has 2200 lumen suitable for Home Cinema use with a RGBRGB color wheel for HDR and Rec709 and Rec2020 color accuracy while the H7850 (2499€ MSRP) is brighter at 3000 lumens using a normal RGBYCMW color wheel achieves HDR Rec2020 compatibility. Both have AccuMotion Frame interpolation for smooth sequences when there is fast movement. Both have 1 million to 1 contrast ratio. This is a nice first step by Acer to bring 4K Projectors into the mass market, I hope that by next year there might be some even more compact sub-$1000 4K DLP projectors on the market. It is awesome to be able to see the 4K quality with HDR on a huge 100-150 diagonal inch display on the wall at home.

The COI Site Tokyo University of the Arts created uses this high quality reproduction of the Vincent Van Gogh self-portrait and they program features to superimpose using an Epson LCD projector to make it look like the painting comes alive. The effect is very impressive. Perhaps for Tokyo 2020 they should exhibit a whole range of famous Art reproductions and statues and have them all come alive, also using sensors, cameras, artificial intelligence smart conversationals systems, to have all the art pieces talk themselves about who painted the originals, stories about why it was painted like that, funny interactions where the painting can talk to you and react to you walking by. The applications seem endless as when the projector projects white it just functions as lighting on the reproduction, but then when those animations subtly superimprose it can really give the effect of movement in the painting.
