Processing technique of glass light guide plate

Abstract

The invention provides a processing technique of a glass light guide plate. The processing technique includes the following steps that: a glass light guide plate is provided, wherein the glass light guide plate is provided with a first surface and a second surface opposite to the first surface; lattice points are marked on the first surface of the glass light guide plate through adopting a laser point marking mode; the first surface is washed through hydrofluoric acid; and the glass light guide plate is washed through water. The glass light guide plate with lattice points which is prepared through the processing technique has the advantages of no chromatic aberration, excellent lattice point effects, no crack, high glass strength, little possibility of being fractured and high light guide performance, and can be produced in a batch manner. With the processing technique adopted, lattice points of which the sizes are smaller than 0.1mm can be produced on the glass light guide plate. According to the glass light guide plate prepared through the processing technique of the invention, ink has little possibility of falling off from the glass light guide plate.

Description

【Technical field】 [0001] The invention relates to the technical field of light guide plates, in particular to the processing procedure of glass light guide plates. 【Background technique】 [0002] The side-lit backlight uses a light guide plate to convert the point light source into a surface light source. Currently, the materials used to make the light guide plate include polymethyl methacrylate (PMMA), methyl methacrylate-styrene copolymer (MS), etc. Then make dots on the bottom surface of the light guide plate by printing, laser dots, etc. Recently, a light guide plate made of glass substrate has been introduced. Its hardness can be dozens of times stronger than that of polymer materials, and it can also make the TV body thinner. There are generally two ways to make dots on the light guide plate made of glass: one is the method of printing dots, which has the advantage of mass production, and its disadvantages are: 1. Due to the difference in chemical properties between i...
