Method of manufacturing the light guide plate of the dot, the light guide plate, backlight module, and a display device

摘要

The present invention relates to a backlight module including the light guide plate dots, a light guide plate manufactured by the manufacturing method and the manufacturing method of the light guide plate of the light guide plate, to provide a display device. Method for producing a dot of the light guide plate, a step S1 for applying a photosensitive material to the surface of the mold core of the light guide plate, subjected to photolithography to said photosensitive material, and a step S2 of forming the dots of the light guiding plate including. Directly because there is no etching the mold core of the light guide plate, since it produced the dots of the light guide plate without destroying the surface of the mold core of the light guide plate, mirror-polishing the cost of the mold core is reduced , the manufacturing process is simple.
