Problems solved by technology

At present, the general light guide plate is made by plastic injection molding method. The light guide plate produced by this method is limited by the design and development of the light guide plate mold, the efficiency of the injection molding machine and the characteristics of the color glue material. The light plate will face problems such as stress marks and warpage that affect the flatness of the light guide plate, which is the key to the thinning of the light guide plate

Embodiment Construction

[0013] The light guide plate and the manufacturing method of the light guide plate of the present invention will be further described in detail below with reference to specific implementation methods and drawings.

[0014] see figure 1 , figure 1 It is a light guide plate 100 according to an embodiment of the present invention. The light guide plate 100 includes an optical fiber plate 31 and a diffusion layer 33 . The optical fiber plate 31 is formed by bonding a plurality of optical fibers 10 side by side. The optical fiber 10 can be a plastic optical fiber or a glass optical fiber. The fiber optic plate 31 has a surface 310 on which the diffusion layer 33 is located. The diffusion layer 33 is composed of polymer colloid and diffusion particles 334 inside the polymer colloid.

[0015] The particle size of the diffusion particle 334 is between 0.1-200um. The diffusion layer 33 includes a light exit surface 112 , which is the light exit surface 112 of the light guide plate ...

Abstract

The invention relates to a light guide plate. The light guide plate comprises an optical fiber plate and a diffusion layer, wherein the optical fiber plate is formed by a plurality of optical fibers which are adhered side by side, the optical fiber plate is provided with a surface, the diffusion layer is located on the surface and is provided with a light outlet surface, the light outlet surface is a light outlet surface of the light guide plate, light outlet holes are distributed in the light outlet surface, and the light guide plate is provided with a light inlet surface perpendicular to the light outlet surface. The invention further relates to a manufacturing method of the light guide plate.

Description

technical field [0001] The invention relates to a light guide plate and a manufacturing method of the light guide plate. Background technique [0002] The light guide plate is a key component of the backlight system, and its function is to guide the light emitted by the point light source or the line light source to be converted into a surface light source through scattering and total reflection by the light guide plate. At present, the general light guide plate is made by plastic injection molding method. The light guide plate produced by this method is limited by the design and development of the light guide plate mold, the efficiency of the injection molding machine and the characteristics of the color glue material. The light plate will face problems such as stress marks and warpage that affect the flatness of the light guide plate. This problem is the key to the thinning of the light guide plate. Contents of the invention [0003] In view of the above situation, it i...
