Keywords:2500:1 contrast ratio? in-vehicle LCD?

Sharp Corp. says it has developed an LCD for in-vehicle applications that achieves the industry's highest contrast ratio of 2,500:1.

Until now, the market for LCDs for in-vehicle applications has been expanding centered mainly on rear-seat entertainment systems to watch TV and DVDs in the back seat, and for car navigation systems. Recently, the trend to incorporate LCDs into the instrument panel has also been accelerating. These LCDs are intended to display read-outs from gauges such as the speedometer, as well as simultaneously display images that enlarge the driver's field of vision and provide visual guidance and safety warnings via connections with cameras and various sensors mounted on the vehicle.

To meet these requirements, Sharp has developed its LCD that features a contrast ratio of 2500:1, while maintaining the high reliability and durability demanded by in-vehicle applications. Sharp developed the product by optimizing the pixel design in the LCD panel and improving the performance of components such as color filters.

According to Sharp, incorporating this LCD into the dashboard will enable improved readability, and the unprecedented deep, rich blacks of the display will make it possible to design high-end instrument panels in which the LCD integrates well into black-colored dashboard.

The 8-inch offers a pixel count of 800 x RGB x 480, and a viewing angle of 176 vertical and 176 horizontal. Luminance is rated at 500 cd/m?. Operating temperature range is from -30C to 85C.
