Paper Abstract

A novel holographic light-guide plate (HLGP) for the illumination of liquid crystal display is proposed in this paper. The holographic film designed for red light (632.8nm) is introduced to the top surface of the wedge-shaped light-guide plate. The backlight system with the HLGP can achieve large gain in uniform illumination. The enhanced illumination uniformity of the emanating light is measured in the experiments.
