Abstract

Lightguides with LED light sources are becoming important components in the application of LCDs for mobile use, because of their thin structures and light weight. Unfortunately, conventional lightguides suffer from poor performance, such as a non-uniform brightness , and this results in poor image and a low efficiency which leads to high power consumption.
