摘要
An assembly for backlighting a liquid crystal flat panel display or other such arrangement requiring backlighting is disclosed herein. The assembly is composed of a multi-reflection light injection system, a light pipe (14), a collimating assembly (28) and a set of specifically configured microprisms (36) which, cooperating with the light pipe, provides an efficient backlighting technique with a controllable degree of collimation. The disclosed assembly may employ up to four light sources to give a brighter backlighting.
