Embodiment Construction

[0027] The steps of the manufacturing method of the light guide plate of the present invention are as follows:

[0028] Perform optical design and perform optical simulations.

[0029] A laser engraving machine is provided, and optical design data is input into the laser engraving machine and converted into processing information and programs.

[0030] A substrate is provided, and the material of the substrate is transparent organic resin, or glass.

[0031] Drive the laser engraving machine to form a plurality of light diffusion points in the substrate according to the processing information and program to form a light guide plate. The plurality of light diffusion points can be processed into hemispherical, spherical, conical or inverted pyramid structures capable of scattering light.

[0032] In addition to the laser internal engraving technique, the manufacturing method of the light guide plate of the present invention can also adopt the ultrasonic internal engraving tech...

Abstract

The invention relates to light guiding plate manufacturing method. It includes the following steps: offer a basal plate; forming many light dispersion structure by inner carving method to form light guiding plate. The method can set different optical texture in the light guiding plate to increase light utilization ratio according to design demand.

Description

【Technical field】 [0001] The invention relates to a light guide plate, in particular to a method for manufacturing a light guide plate that can reduce light loss and improve light utilization. 【Background technique】 [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as notebook computers, various desktop computers, and LCD TVs. Because the liquid crystal display is a passive device, it cannot emit light by itself, so it is necessary to use a light source system as the light source of the liquid crystal display, such as a backlight module (Backlight Module), wherein the light guide plate is an important component in the backlight module. In order to guide the transmission direction of the light beam emitted from the light source, the line light source or point light source is converted into a surface light source to emit. [0003] In order to improve the uniformity of the light output,...
