Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses a light diffusion plate manufacturing method, a light diffusion plate and a backlight module. The light diffusion plate manufacturing method comprises the steps that an intermediate light diffusion particle agent is injected into the middle part of a manufacturing table, an edge light diffusion particle agent is separately injected into both sides of the middle part, and the concentration of light diffusion particles in the intermediate light diffusion particle agent is greater than the concentration of light diffusion particles in the edge light diffusion particle agent; and after the intermediate light diffusion particle agent and the edge light diffusion particle agent are combined and solidified, the light diffusion plate is formed. The light diffusion plate effectively solves the problem that shadows appear at four corners when light passes through an existing light diffusion plate.

Description

technical field [0001] The invention relates to the field of backlight display, in particular to a method for manufacturing a light diffusion plate, a light diffusion plate and a backlight module. Background technique [0002] In existing backlight display technologies, subjective visual effects have always been the focus of users' attention. Regarding the visual effect problem, the main problem of the direct display terminal is that there are always shadows at the four corners of the direct display terminal, which leads to poor overall display effect of the direct display terminal when the user uses the direct display terminal. In the optimization process of the direct display terminal, even if the curvature of the back panel, the light angle of the lens, or the assembly of the reflector are optimized, the shadow problem at the four corners of the direct display terminal still exists. [0003] Therefore, it is necessary to provide a new method for manufacturing a light dif...
