Example Embodiment

[0012] Embodiment: A composite light guide plate has 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 is a front and a back respectively, the transparent The film is attached to the back of the transparent substrate. In the present invention, the light guide dot is printed on the transparent film first, and then the transparent film printed with the light guide dot is combined with the transparent substrate to form a light guide plate. Since the light guide dot is printed on the transparent film, it is better than the prior art Direct printing on the transparent substrate is easier to achieve, reduces the difficulty of the process, and improves the process yield. Moreover, even if there is a bad scrap, only the transparent film part needs to be scrapped, and the transparent substrate part is intact, thus reducing the cost.

Abstract

The invention discloses a composite light guide plate, which comprises a transparent base plate and a transparent film, wherein a plurality of light guide points are printed on the transparent film and attached to the back of the transparent base plate. The light guide points are firstly printed on the transparent film, and then the transparent film printed with the light guide points is combined with the transparent base plate, so as to form the light guide plate, the light guide points are easier to be printed on the transparent film than to be directly printed on the transparent base plate in the prior art, the difficulty in the manufacturing process is further lowered, the process yield is improved, even if a defect product exists, only the transparent film is discarded, and the transparent base plate is intact, therefore, the cost can be reduced.

Description

technical field [0001] The invention belongs to the field of photoelectric materials, and in particular relates to a light guide plate for illumination or display. Background technique [0002] The light guide plate is a high-tech product that converts linear light sources into surface light sources. The light guide plate in the prior art uses an optical-grade acrylic (PMMA) plate, and then prints light-guiding points on the bottom surface of the optical-grade acrylic plate with an ink that has a very high reflectivity and does not absorb light. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light...
