Problems solved by technology

[0004] At present, anti-glare glass preparation technology mainly uses chemical corrosion methods such as hydrofluoric acid and sulfuric acid to process the glass surface into a relatively rough surface, but there are some defects, such as the uneven flow of corrosive liquid on the glass surface will make the processed glass Defects are caused by certain lines; after the corrosive liquid is sprayed on the glass surface, it is difficult to control the process parameters such as corrosion time and spray pressure, resulting in uneven structure of the glass surface and poor performance; when processing single-sided anti-glare glass, it will be caused The corrosive liquid penetrates into the back of the glass and causes defects; the light transmittance of the glass processed by the chemical corrosion method is low, which cannot meet the requirements of high light transmittance, which seriously affects the imaging effect of the product; due to the strong corrosiveness of strong acid, it is harmful to the environment Cause a lot of pollution, and it is easy to cause harm to the operator's body

Abstract

A preparation method of anti-dazzle glass includes the steps of: (a) depositing a layer of ZnO thin film on a surface of a glass substrate; (b) etching the ZnO thin film with an acid solution or an alkaline solution in low concentration to form a three-dimension mask plate; and (c) etching the glass with the three-dimension mask plate ZnO thin film formed thereon with plasma to prepare the glass having an uneven structure. In the method, the anti-dazzle glass is prepared by pre-preparing the three-dimension mask plate and then performing plasma etching. The method has high etching speed and uniform etching pattern and can be used for forming a uniform uneven structure. The anti-dazzle glass has excellent anti-dazzle performance, has low damage on human body and is suitable for a high-grade display panel.

Description

technical field [0001] The invention relates to a preparation method of anti-glare glass, in particular to the fields of TV splicing walls, outdoor super-large display screens, flat-screen TVs, rear-projection TVs, liquid crystal displays, touch screens, industrial instruments, and advanced picture frames. Background technique [0002] Anti-glare glass, also known as non-reflective glass or anti-reflective glass, is a kind of glass whose surface is specially treated. Compared with glass, it has a lower reflectance, basically does not affect the transmission of light, and the reflectance of light is reduced from 8% to less than 4%. [0003] In our daily life, we all have the experience of being attacked by glare, partly from the glare light source, and partly from the reflection of glare; when we operate the computer, we are often troubled by the reflection of the scenery outside the monitor on the surface of the monitor and cannot see the displayed content clearly; Another ...
