Light guide plate manufacture method and device

Abstract

The invention discloses a light guide plate manufacture method, which comprises the following steps that: S1, an optical distribution map of a light guide plate is manufactured by using optical analysis software; S2, the optical distribution map is subjected to gray level grading from shallow to deep and is directly divided into a plurality of different gray levels; S3, different laser energy is emitted according to different gray levels; and S4, light guide points with different depths are generated on the light guide plate by labeling equipment according to different laser energy. The invention also discloses a light guide plate manufacture device. When the light guide plate manufacture method and the light guide plate manufacture device provided by the invention are implemented, laser net points are realized by a pure physical method, the environment is protected, no chemical pollution is caused, durability is realized, the production efficiency is greatly improved, the energy is saved, and the light ray material internal loss is reduced.

Description

technical field [0001] The invention relates to an acrylic plate, in particular to a method and device for manufacturing a light guide plate. Background technique [0002] As we all know, the light guide plate is made of an optical grade acrylic plate, and light guide points are made on the bottom surface of the acrylic plate. The optical grade acrylic sheet is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the light guide plate. Front shot. Through various light guide points, the light guide plate emits light evenly. [0003] Light guide plates are developing rapidly in the LED application industry. At present, printed dot light guide plates are the mainstream in the market, and there are also light guide plates with laser scribing and tool engraving line grooves. [0004] For th...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the use of ink printing, a large amount of chemical materials are required, which causes great environmental pollution;

[0007] 2. The optical stability of ink dots is poor, which cannot adapt to the durable characteristics of the LED industry;

[0008] 3. The printing dot light guide plate has high environmental requirements, and the influence of humidity and ultraviolet rays on the dots is very great;

[0009] 4. The production environment has high requirements, high cost and high defect rate;

[0010] 5. The production process is complicated;

[0014] 2. The optical distribution is very poor;
