Therefore, a light source system is required as a light source of the liquid crystal display, such as a backlight module (Backlight M_le), wherein the light plate is an important component of the Xiaoguang module towel for guiding the light beam from the light source. The transmission direction 'converts the line source or the point source into a surface source. To improve the uniformity of light emission, a plurality of nets are generally disposed on the surface of the light guide plate, and the total reflection condition for destroying the transmission of the light beam inside the light guide plate is generally employed. And scattering it to improve the uniformity of the light beam emitted by the light guide plate, thereby improving the overall performance of the backlight module. At present, the manufacturing method of the light guide plate dots can be roughly divided into the trend of printing and non-printing processes. The non-printing system reduces the design of the guide film (light guide plate surface) on the mold, and uses direct molding or embossing to produce a light guide plate with a uniform light pattern.
