Title: On-vehicle liquid crystal display device
Inventor: KOIWAI HIDEAKI
IPC: G09F9/00
Filed: 1989-05-26
Abstract: PURPOSE:To improve the instantaneous brightness rise characteristic of a liquid crystal back light at cryogenic temperature and to decrease the surface temperature of a liquid crystal panel at high temperatures by arranging an infrared-ray cutting filter between the liquid crystal panel and a fluorescent lamp and arranging a xenon lamp at the periphery of the panel. CONSTITUTION:The infrared-ray cutting filter 25 is arranged between the liquid crystal panel 21 and fluorescent lamp 22 and the xenon lamp 23 is also arranged at the periphery facing the liquid crystal panel 21 between the liquid crystal panel 21 and infrared-ray cutting filter 25. Therefore, compensation is performed by the xenon lamp at cryogenic temperatures before the fluorescent lamp 22 reaches sufficient brightness, and the fluorescent lamp 22 is sealed with the infrared-ray cutting filter 25 and a reflecting plate 24 to improve temperature rise efficiency. When the ambient temperature is high, on the other hand, the quantity of lamp radiant heat reaching the panel surface can be decreased by the infrared-ray cutting filter 25. Consequently, the instantaneous brightness rise characteristic of the liquid crystal back light at cryogenic temperatures is improved and the quantity of radiant heat from the back light is reduced at high temperatures to reduce a rise in the panel surface temperature.
