Embodiment Construction
[0047] In order to further illustrate the mold core of the light guide plate provided by the embodiments of the present invention, its manufacturing method, and the light guide plate, a detailed description will be given below in conjunction with the accompanying drawings.
[0048] see Figure 1~3 , the manufacturing method of the mold core of the light guide plate provided by the embodiment of the present invention includes:
[0049] Step S101, providing a mold core body 1, the surface to be processed of the mold core body 1 includes a mold core dot forming area 30 and a non-mold core dot forming area 31;
[0050] Specifically, since the size of the mold core body 1 determines the size of the formed light guide plate mold core, and the size of the light guide plate mold core determines the size of the formed light guide plate, when selecting the mold core body 1, you can According to the size of the light guide plate to be prepared later, a suitable mold core body 1 is selec...

Abstract
The invention discloses a mold core for a light guide plate, a manufacturing method thereof, and a light guide plate, and relates to the field of display technology, in order to solve the problem that the dot scattering angle of the light guide plate formed by using the existing light guide plate mold core is small, which leads to the light energy utilization of the light guide plate low rate problem. The manufacturing method of the mold core of the light guide plate includes: providing a mold core body, the surface to be processed of the mold core body includes a mold core dot formation area and a non-mold core dot formation area; forming a mold core in the mold core dot formation area. Core network point, the mold core network point includes a mold core convex part and a mold core concave part; a covering layer covering at least the mold core convex part is formed. The manufacturing method of the mold core of the light guide plate provided by the present invention is used for making the mold core of the light guide plate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a mold core for a light guide plate, a manufacturing method thereof, and a light guide plate. Background technique [0002] With the continuous development of display technology, liquid crystal displays are used more and more widely. Since liquid crystal itself does not have a light-emitting function, it is necessary to set a backlight module in the liquid crystal display to provide a uniform surface light source for the liquid crystal display, so as to realize the liquid crystal display. display effect. [0003] A backlight module generally includes a light source, a light guide plate, a reflector, a prism sheet, a diffusion film, etc. The light guide plate is the main device for converting a line light source or a point light source into a uniform surface light source. The specific conversion method is through the light guide plate. The reflective surface is provided with dot...
