Abstract
Direct-light type backlight module is widely used for large size liquid crystal displays (LCDs). Many methods have been proposed to thinner the thickness and simplify the structure. In this paper a new kind of diffuser, with micro prisms on the top and micro spheres on the bottom, is used to reduce the thickness for the direct-light type backlight module. Simulated results show the microstructures on the diffuser can help to reduce the thickness between the diffuser and the light source, while keeping the illumination uniformity and increasing the light efficiency.
