LIGHT GUIDE PLATE LATTICE POINT MANUFACTURING METHOD, LIGHT GUIDE PLATE MANUFACTURING METHOD, BACKLIGHT MODULE, AND DISPLAY APPARATUS

摘要

The present disclosure provides a fabricating method of grid points on light guiding plate, a fabricating method of light guiding plate, and a backlight module and a display device. The fabricating method of grid points on a light guiding plate. The fabricating method of grid points on a light guiding plate comprises following steps of: S1, forming a layer of photosensitive material on a mold for the light guiding plate; and S2, performing photolithography on the photosensitive material in order to form grid points on the light guiding plate. According to present disclosure, since the mold for the light guiding plate is not etched directly, but the grid points is formed on the layer of photosensitive resist applied on the mold, therefore the grid points on the light guiding plate can be made without damaging the surface of the mold for the light guiding plate, and the cost for polishing the mold surface is saved and the overall process is simplified.
