Problems solved by technology

At present, there are generally three ways to make glass light guide plate dots: one is screen printing, which has the advantage of being mass-produced, but has some disadvantages: 1. The chemical properties of ink and glass are different, which is easy to produce color difference; 2. The ink is attached Poor focus, easy to peel off or partially peel off; 3. The mass production of ultra-small dots is poor; the other is to make dots by laser dots, but it is easy to produce tiny cracks around the dots, which affects the strength of glass and product quality; the third way is to use The dots of the light guide plate are formed by etching with hydrofluoric acid, but the process is complicated and complicated, which is not conducive to mass production

Abstract

The invention relates to a preparation method of a glass light guiding plate. The method comprises the following steps of: 1) heating a glass substrate to a semi-molten state, and taking one surface of the glass substrate as a mesh point surface; 2) when the mesh point surface is in the semi-molten state, forming mesh points on the mesh point surface in a laser dotting mode and then cooling the mesh point surface to obtain the glass light guiding plate. The preparation method of the glass light guiding plate is simple and quick, is suitable for mass production, and no cracks exist around the mesh points of the glass light guiding plate prepared by the method, so that the glass strength of the glass light guiding plate is greatly improved, the optical performance of the glass light guidingplate is improved, and the service life of the glass light guiding plate is prolonged.

Description

Technical field[0001]The present invention relates to the field of light guide plates, and more particularly to a method of preparing a glass light guide plate.Background technique[0002]In the liquid crystal display, the light guide plate is mainly used to convert the line light source from the light source to a surface light source to uniform brightness of the display picture. The material of the conventional light guide plate has polymethyl methacrylate (PMMA), polycarbonate (PC), etc. In recent years, a light guide plate made of a glass substrate, which is more intensity than the long-size light guide plate strength, in large size The module is thinner on the TV product. At present, there are three ways to make the glass light guide mesh: one is a screen printing method, and the advantage is that it can be mass production, but there are some disadvantages: 1. There are differences in chemical properties of the glass and glass; 2. Ink Poor power, easy to peel off or partially peel...
