Embodiment
[0012] Embodiment: a composite light guide plate, with a transparent substrate 1 and a transparent film 2, the transparent film is printed with a number of light guide points, the transparent substrate has two opposite surfaces and are respectively the front and the back, the transparent A film is attached to the back of the transparent substrate. In the invention, the light guide points are first printed on the transparent film, and then the transparent film printed with the light guide points is combined with the transparent substrate to form a light guide plate. Since the light guide points are printed on the transparent film, it is better than the prior art It is easier to print directly on the transparent substrate, which reduces the difficulty of the process and improves the yield rate of the process. Even if there is a defective scrap, only the transparent film part needs to be scrapped, while the transparent substrate part is intact, so the cost can be reduced.
