Abstract

Wherein, the plate comprises a light-input surface, a near light-output surface, a bottom opposite to the light-output surface, and a plurality of through holes every with at least one end through bottom or the light-output surface in the plate. This invention has high light usage.

Description

【Technical field】 [0001] The invention relates to a light guide plate. 【Background technique】 [0002] Since the liquid crystal in the LCD panel itself does not have light-emitting characteristics, in order to achieve the display effect, it is necessary to provide the LCD panel with a light source device, such as a backlight module, whose function is to supply the LCD panel with a surface with sufficient brightness and uniform distribution. light source. [0003] The prior art backlight module is composed of a light source, a reflector, a light guide plate, a diffusion plate, and a prism layer. The light guide plate is a key component in the backlight module, and its function is to guide the incident light to be scattered and reflected by the light guide plate and converted into surface light source. [0004] Please see figure 1 , is a schematic diagram of an existing backlight module. The backlight module 200 includes a light source 210 , a light guide plate 220 , a ref...
