In-vehicle LCD has 1500:1 contrast ratio

7 March 2007 Opto-Electronics

Combining superior image quality with high durability, Sharp says that its High Contrast display offers new opportunities for design of vehicle panels and car infotainment systems or environments of high ambient light conditions.

This newly developed LCD for in-vehicle applications features a contrast ratio of 1500:1, which it believes is the highest currently for such a display.

The re-engineering of various display components, in particular, the colour filter, and the revamping of the LCD panel's pixel design, made it possible to achieve a display that delivers unprecedented deep and rich blacks.

Compared to consumer product LCDs, in-vehicle LCDs used in car navigation systems and as monitors for rear-seat entertainment systems must be more resistant to vibration and must function reliably over a broad range of temperatures. Consequently, the new high contrast display is designed for an operating temperature of -30 to 85°C. In addition, the wide viewing angle of 176° in all directions ensures clear vision from all seats.

The High Contrast LCD can, for example, be adopted for use in instrument panels to improve the readability. It could display, among other things, the speedometer reading when driven, but when parked, that same LCD can provide the driver with a map or a video image of behind the vehicle.

Sharp's High Contrast display has a screen size of 20 cm, a 800 x RGB x 480 pixel count, and 400 cd/m² luminance.
