Abstract

An optical plate includes a transparent baseplate and a diffusion layer. The transparent baseplate includes a light reflecting surface and a connecting surface corresponding to the light reflecting surface. The transparent baseplate forms a plurality of strip-shaped grooves on the connecting surface. The diffusion layer is attached to the connecting surface and fills a plurality of grooves. The optical plate adopts a backlight module featured by thin thickness.

Description

Optical board and backlight module using the optical board technical field The invention relates to an optical plate applied to a liquid crystal display device and a backlight module using the optical plate. Background technique In recent years, liquid crystal displays have been widely used due to their lightness, thinness, small size and low power consumption. Since the liquid crystal display panel itself does not have light-emitting properties, a backlight module is required to provide it with a backlight tube to realize the display function of the liquid crystal display panel. Please refer to FIG. 1 , which is an exploded view of a conventional backlight module 10 . The backlight module 10 includes a prism sheet 12, a diffusion sheet 13, a diffusion plate 14, a plurality of lamp tubes 15 and a reflector 11, the lamp tubes 15, the diffusion plate 14, the diffusion sheet 13 and the prism sheet 12 are arranged in sequence above the reflecting plate 11. Wherein, the dif...
