BACKLIGHT MODULE

摘要

An exemplary backlight module includes a substrate, a lighting chip mounted on the substrate and a light diffusion board located above the lighting chip. The light diffusion board includes a main body and a diffusion-enhancing portion arranged in the main body. The diffusion-enhancing portion has higher light diffusibility than that of other portion in the main body. The lighting chip is aligned with the diffusion-enhancing portion. The diffusion-enhancing portion has a light diffusibility which is gradually decreased from a center of the diffusion-enhancing portion toward a periphery of the diffusion-enhancing portion.
