Backlight Unit with Double Surface Light Emission Using a Single Micro-Structured Light-Guide Plate( Electronic Displays)

摘要: A double surface light emission backlight that uses single light-guide plate, has been developed for illumination of two liquid-crystal displays (LCD) on its front and rear, to be used in a cellular phone. The plate trapezoid cross-section with arrays optical micro deflector prism the rear surfaces, respectively. Propagated light, forward backward, inside are controlled directed toward LCDs using only sheets internal reflection characteristic, each rear. Only three components four light-emitting diodes (LEDs) new structure compared ten six LEDs current type. Comparing type, thickness power consumption reduced by factor 0.59 0.67,
