    • A flat panel display system utilizing a light pipe having vapor deposited highly reflective material on a light pipe. The flat panel display may be used in a portable electronic device. One embodiment discloses deposition of a highly reflective material (e.g., SiO2 or TiO2) around the non-viewing areas of a light pipe that provides light to the display screen. Front lighting embodiments and back lighting embodiments are described. One embodiment further discloses deposition of reflective material on the surface of microstructures of the light pipe to enhance light reflection and to prevent light escape. Another embodiment of the present invention discloses the coating or vapor deposition of phosphor material on the light pipe. This embodiment utilizes a blue light or IR light with the phosphor layer, to create a long lasting white light which is appealing for many portable electronic device displays.
    • 一种利用在光管上具有气相沉积的高反射材料的光管的平板显示系统。 平板显示器可以用在便携式电子设备中。 一个实施例公开了将高反射材料(例如,SiO 2或TiO 2)沉积在向显示屏提供光的光管的非观察区域周围。 描述前照明实施例和背光照明实施例。 一个实施例进一步公开了在光管的微结构的表面上沉积反射材料以增强光反射并防止光逸出。 本发明的另一实施例公开了在光管上涂覆或蒸镀磷光体材料。 该实施例利用蓝色光或IR光与荧光体层,以产生持久的白光,其吸引许多便携式电子设备显示器。
