Sharp vient d'annoncer hier qu'il allait proposer des écrans LCD pour auto de 8 pouces avec une résolution de 800x480 possédant un ratio de 1500:1 pour le contraste et une luminosité de 400cd/m2, qui est pour le contraste 3 fois meilleur que ce qui se fait de mieux dans le monde auto actuellement ! Ce type de LCD sera donc utilisé pour plusieurs systèmes comme une caméra de recul, GPS, compteur vitesse…
Sharp Develops the Industry’s Highest*1 1500:1 Contrast Ratio In-Vehicle LCD
Capable of Displaying Deep, Rich Blacks that Match Instrument Panel Designs
Sharp Corporation has successfully developed an LCD for in-vehicle applications that achieves a contrast ratio of 1500:1, the industry’s highest. Compared to LCDs for consumer products such as personal computers and TVs, invehicle LCDs used in car navigation systems and as monitors for rear-seat entertainment systems must be more highly resistant to vibration and must function reliably over a broad range of temperatures. Recently, the widening selection of maps and the proliferation of video titles on DVD are driving a shift to even larger screen sizes and higher resolutions. Moreover, it is expected that in-vehicle LCDs will be further developed for use in instrument panels to display important information needed for driving a car.
The re-engineering of various display components, in particular, the color filter, and the revamping of the LCD panel’s pixel design made it possible to achieve a display that delivers unprecedented deep, rich blacks and has a contrast ratio of 1500:1—the industry’s highest and triple that of previous models*2—while maintaining the high durability and reliability demanded of an in-vehicle display.
This new LCD can, for example, be adopted for use in instrument panels to make them easier to read. It provides outstanding design options, evoking a strong unified appearance when coupled unobtrusively with the typical flat black color of instrument 2 of 2 panels. When the vehicle is being driven, this new LCD can display, among other things, the speedometer reading. When it is being parked, that same LCD can provide the driver with a map or a video camera image of the area behind the vehicle. A wide variety of displays previously impossible using mechanical meters are now possible—all contributing to the safety and comfort of drivers.
As the world’s leading manufacturer of LCDs, Sharp has consistently developed invehicle displays that give rise to new applications, including the Dual Directional Viewing LCD (formerly called the two-way viewing-angle LCD) and the Triple Directional Viewing LCD. Sharp will continue to develop highly reliable, advanced displays by integrating technologies nurtured over long years of experience in developing a wide range of LCD application products and will lead the growing market for in-vehicle LCDs.
