A Colloidal Display: membrane screen that combines transparency, BRDF and 3D volume. Nanotechnologists change color of water using magnetic fields. University of California, Riverside nanotechnologists have succeeded in controlling the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution. The discovery has potential to greatly improve the quality and size of electronic display screens and to enable the manufacture of products such as erasable and rewritable electronic paper and ink that can change color electromagnetically.
When the strength of the magnetic field is changed, it alters the arrangement of the spherical iron oxide particles in solution, thereby modifying how light falling on the particles passes through or is deflected by the solution.In their experiments, the researchers found that by changing the strength of the magnetic field they were able to change the color of the iron oxide solution - similar to adjusting the color of a television screen image.

P-Ink color change by electric field. Semiconductor structure bends light 'wrong' way. A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats. The new substance is in a relatively new class of materials called "metamaterials," which are made out of traditional substances, such as metals or semiconductors, arranged in very small alternating patterns that modify their collective properties.
This approach enables metamaterials to manipulate light in ways that cannot be accomplished by normal materials. In the case of the straw in a glass, normal water would make the underwater portion of the straw appear to bend toward the surface. 觸控面板貼合. Learn About LCD TV and TFT LCD Displays. TFT LCD - Fabricating TFT LCD Fabricating Color TFT LCD Displays The pressure to reduce the manufacturing cost of TFT LCD displays is as constant and intense as it is in the semiconductor industry.
To increase productivity, IC makers continuously reduce the sizes of c-Si chips and transistors in order to increase the number of chips per wafer. IC makers increase productivity by continuously reducing chip size and increasing wafer size to increase the number of chips per wafer. But this strategy doesn't work for LCDs because the panel sizes users demand most get steadily larger, not smaller.
The IC makers' size-reduction strategy doesn't work for direct-view LCDs, but LCD manufacturers can still reduce the cost of TFT-array processes by increasing the number of panels produced on a single substrate. This process requires that the size of the glass substrate be steadily increased so that the number of LCD panels fabricated upon it can increase. Fabricating the TFT array TFT Fabrication.
DisplaySearch Blog | The Official Blog of DisplaySearch, an NPD Group Company. Electronic paper. Electronic paper, e-paper and electronic ink are display technologies which are designed to mimic the appearance of ordinary ink on paper.[1] Unlike conventional backlit flat panel displays which emit light, electronic paper displays reflect light like ordinary paper, theoretically making it more comfortable to read, and giving the surface a wider viewing angle compared to conventional displays. The contrast ratio in available displays as of 2008 might be described as similar to that of newspaper, though newly developed displays are slightly better.[2] An ideal e-paper display can be read in direct sunlight without the image appearing to fade.
Many electronic paper technologies can hold static text and images indefinitely without using electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. There is ongoing competition among manufacturers to provide full-color ability. Technologies[edit] Gyricon[edit] Electrophoretic[edit] Display Technologies Knowledge Platform. Comparison of display technology. This is a comparison of various properties of different display technologies. General characteristics[edit] Temporal characteristics[edit] Different display technologies have vastly different temporal characteristics, leading to claimed perceptual differences for motion, flicker, etc. The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale. Notice that some have a fixed intensity, while the illuminated period is variable. Single-chip DLPs use a kind of "chromatic multiplexing" in which each color is presented serially.

Mercedes-Benz Introduces New SPLITVIEW COMAND Display For The S-Class | eMercedesBenz - The Unofficial Mercedes-Benz Weblog. Mercedes has announced today that starting in the summer of 2009, S-Class models will feature a new technology they're calling SPLITVIEW. Developed in collaboration with Bosch, SPLITVIEW will allow both the driver and passenger to view two separate programs via the same COMAND display.
For example, let's say the vehicle's operator is in the process of viewing navigation directions, the front passenger can simultaneously watch a film on the exact same 8-inch display. You may be wondering what magic lies behind the SPLITVIEW system, and the answer lies in pixel placement. The COMAND screen shows two different images simultaneously by placing pixels adjacent to one another, after which a filter masking the display divides this mixed image so that depending on seating position, either one image or the other can be seen. As already noted, the SPLITVIEW system will make its debut next summer, found on the S-Class sedan lineup. Enjoy ladies and gentlemen. Copyright © 2008, Daimler AG.

New. IT'S being hailed by its developers as the next revolution in visual technology - a laser television that will make plasma screens obsolete. Soon-to-be-listed Australian company Arasor International and its US partner Novalux unveiled what they claimed to be the world's first laser television in Sydney today, with a pitch that it would be half the price, twice as good, and use a quarter of the electricity of conventional plasma and LCD TVs.
Manufacturing company Arasor produces the unique optoelectronic chip central to the laser projection device being developed by Silicon Valley-based Novalux, which is being used by a number of television manufacturers. And displayed beside a conventional 50 inch plasma TV this afternoon, the Mitsubishi-built prototype does appear brighter and clearer than its “older” rival.
“If you look at any screen today, the colour content is roughly about 30-35 per cent of what the eye can see,” he said. “All of a sudden what you see is a lifelike image on display.” 3D. Panoptic C-Thru 3D Video Surveillance System. August 31, 2006 Panoptic’s proposed C-Thru 3D Video Surveillance System could be loosely described as a formalised, scalable implementation of Superman’s X-ray vision. The system enables one or more surveillance agents, using a single high resolution, auto-stereoscopic display, to remotely monitor the security situation of an arbitrarily large number of locations at-a-glance. Agents can see, hear and transport their focused viewpoint through walls, floors and ceilings, zooming into a specific location to monitor it at a level so acute that it seems beyond the levels of even science fiction. Designed to enable both wholistic site-wide and granular-level security, the system is ideal for monitoring airports, shipping ports, transit sites and other ports-of-entry, hotels, casinos, shopping malls, campuses, military bases, large buildings and building complexes, offering total situational awareness at a glance.

Gemotion screen shows video in living 3D. 22 Jan 2007 Here's a groovy display for people looking to add that extra dimension to their viewing material... Gemotion is a soft, 'living' display that bulges and collapses in sync with the graphics on the screen, creating visuals that literally pop out at the viewer. Yoichiro Kawaguchi, a well-known computer graphics artist and University of Tokyo professor, created Gemotion by arranging 72 air cylinders behind a flexible, 100 x 60 cm (39 x 24 inch) screen. As video is projected onto the screen, image data is relayed to the cylinders, which then push and pull on the screen accordingly.
"If used with games, TV or cinema, the screen could give images an element of power never seen before. It could lead to completely new forms of media," says Kawaguchi. The Gemotion screen will be on display from January 21 to February 4 as part of a media art exhibit (called Nihon no hyogen-ryoku) at National Art Center, Tokyo, which recently opened in Roppongi.

LG is unveiling a display that is illuminated by sunlight while outdoors, which means it helps decrease power consumption of notebooks by 75% while outside. The company's new 14.1" LCD display is the first display of its kind to utilize this technology: Leveraging LG Display's "Backlight Data Signal Switching Technology", the use of selective reflection plates in existing backlight panels enables the switch from reflective mode in a high luminance setting (sunlight) to transmissive mode in a low luminance setting (indoors and at night).
This is the first LCD panel to allow users to easily switch from backlight use (transmissive mode) to outdoor reflective mode with the touch of a button. That means the amount of battery power needed to run the notebook while outside falls to just 25% of previous levels. We'll catch more details as we can at CES in January 2009 - this might end up being a very cool product. Samsung demos transparent LCD using ambient backlight.
LCD and Solar cell in one. Patent Monkey: LCD + Solar Cell = Smart. Cell phone battery life has been one of the top problems since its inception. Motorola was there at the beginning, and is at least exploring smart solutions. Motorola recently received a patent for combining an LCD screen and a solar cell on a wireless device. While the cost of such a concept makes the iPhone seem like a bargain, the concept of having a display that also can have a dual purpose of receiving light for recharging the battery makes a lot of sense. Moto’s patent notes that this technology is better with black-only LCDs achieving up to a 75% light let-through rate. In the market, thin film solar cell development has come a ways since this technology was filed.
In thin-film processing of solar cells, Wikipedia notes: Many new solar cells use transparent thin films that are also conductors of electrical charge. The concept has been of interest for a number of years by a few different players including Seiko, Minolta and Sharp. LCD adjustable. Researchers in Taiwan have developed a computer screen that provides sharper images by adjusting itself automatically to the viewer's line of vision.
The technology prevents the users from seeing a blurred or distorted image when viewing a liquid crystal display (LCD) from an angle instead of straight on, say its developers. Normally, altering the angle of the liquid crystals held between two polarising elements controls the brightness of each pixel in an LCD. The crystals act like tiny valves, varying the amount of light that can pass through. As such, when a viewer looks at an LCD from one side, they effectively alter the viewing angle of these crystals, which reduces the brightness and contrast of a pixel and distorts the clarity and colours of an overall image. The prototype display developed by Cheng and Wu connects to a miniature camera that tracks the location of the viewer's head. Source: zeenews.com.
