Abstract
Liquid crystal displays have many good qualities, such as ultrathinness, light weight, high brightness, and so forth. It is very important to improve the display performance of backlight module systems to provide better uniformity, brightness, lower power consumption, and lower weight. In backlight modules, the light guide plate (LGP) is a key component in reducing the cost and easier access to develop LGPs on its own. This research proposes the concept of Back Light Unit (BLU) with external illuminance. This special optical design may introduce the external light into BLU in order to improve the power-saving. One is for 14 inch monitor, which has 21% improvement. Another for 3.5 inch display might have improvement 15%.
