Description

【Technical field】 [0001] The invention relates to a light guide plate and a manufacturing method thereof, in particular to a light guide plate with a diffusion function and a manufacturing method thereof. 【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 a light source device for the LCD panel, such as a backlight module, whose function is to supply sufficient brightness and uniform distribution to the LCD panel. surface light source. [0003] The existing 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 converted into surface light source. In order to make the luminance of the surface light source more uniform, a diffuser plate is usually arra...
