Japan Display Corporation has developed an in-vehicle display that uses a rectangular curved liquid crystal panel and a head-up display (HUD), and was displayed at the "Display Innovation 2014" (October 29-31, 2014) held at the Yokohama International Convention and Exhibition Center in the Pacific. . The rectangular curved LCD panel is used for the instrument cluster in front of the driver's seat, and two 10-inch curved LCD panels are spliced ​​to the left and right. By adopting a rectangular shape, a wide range of display and design properties are taken into consideration. The HUD is used to project a liquid crystal panel image displaying a navigator and reminder information onto the front window glass. This article refers to the address: http:// In the demonstration of the curved display, the Japanese display company showed the use of meters and maps such as speedometers in the central part, and used both ends as electronic mirrors. The curvature of the curved display is 500mm. The 12-inch curved LCD panel demonstrated in 2013 uses amorphous silicon (a-Si) TFT with a resolution of 245 ppi, and the 10-inch curved LCD panel has a resolution of 308 ppi due to the use of low temperature polysilicon (LTPS) TFT. The pixel is 2880×1080. In addition, this product has also adopted two new low-power technologies. One is the color display method that the company calls "WhiteMagic", which uses a four-color color filter (CF) that adds W (white) to RGB. The other is the “local dimming†technique, which controls the backlight brightness according to the area of ​​the display. The backlight is edge-lit. The HUD LCD panel has a screen size of 3.1 inches, a pixel of 800 x 480, and a resolution of 297 ppi. Also suitable for high-definition LTPS TFTs. In addition, IPS liquid crystal technology that Japanese display companies are good at is also used. Compared with the usual TN method, it has the characteristics of large viewing angle.
