Problems solved by technology

Directly mechanically grind the surface of the display screen or selectively corrode the surface with hydrofluoric acid and other corrosive agents to make the surface rough. The transparency of the screen is easier to accumulate dust, which is the mainstream of domestic production

Abstract

The invention discloses an anti-dazzle method for optical glass by a wet process. The method specifically comprises the following steps: cleaning, wind-shearing and drying a to-be-processed fresh glass substrate in a dust-free environment; further cleaning the glass substrate by adopting a plasma gas, and roughening the surface of the glass; pre-heating the substrate and maintaining constant temperature; adjusting parameters of a spraying process; coating an anti-dazzle liquid by way of ultrasonic atomization; placing, leveling and carrying out surface dry after coating; roasting and curing to form a film; and slowly cooling the substrate to room temperature and preparing the anti-dazzle glass after examination. Compared with existing anti-dazzle technology, the hardness is increased from 2H to over 5H compared with that of a straight sticker. Compared with conventional anti-dazzling in an etching method, environment-friendliness is realized and Moore phenomenon is reduced. The cleanness is further enhanced and the film binding force is improved by adopting the plasma gas to roughen the glass substrate. The effect of ultrasonic atomization is better than that of common aerodynamic discretion. The atomizing particles are smaller and more uniformly dispersed.

Description

Technical field [0001] The invention relates to an anti-glare method for glass, in particular to a wet anti-glare method for optical glass. Background technique [0002] At present, electronic display devices are attracting more and more attention from customers, and their applications will become wider and wider. However, the resolution of high-resolution display devices under poor viewing conditions such as direct sunlight and high illuminance will be affected, and the picture will be distorted. Therefore, it is necessary to perform anti-glare treatment on the cover glass of the display device to change the original reflective surface. It becomes a matte diffuse reflection surface to reduce the interference of ambient light. [0003] Sticking the anti-glare film directly on the equipment can achieve the above purpose, but the hardness of the film product is very low. In addition to the film, the anti-glare performance is basically obtained through the following two ways: dry fi...
