碩士 === 國立交通大學 === 光電系統研究所 === 99 === We introduce the novel backlight module, which consists of the hybrid light guide plate, brightness enhancement film and a top diffuser. The HLGP comprises the functions of the conventional light guide plate, the reflector, and the BEF. The HLGP allows one-dimensional rays to be collimated. We add the BEF above the HLGP, and let the crossed-dimension rays to be collimated. Comparing with the conventional edge-lit backlight module, the optical efficiency improves to 1.3-times and the on-axis luminance improves to 3.6-times by using the novel backlight module.
