Low-reflection high-resolution glass

Abstract

The invention discloses low-reflection high-resolution glass. The glass comprises substrate glass (4), on which an upper anti-dazzle layer (3), an upper anti-reflection layer (2) and an upper protective layer (1) are successively laminated and below which a lower anti-dazzle layer (5), a lower anti-reflection layer (6) and a lower protective layer (7) are successively laminated. Thickness of bothupper and lower protective layers is 1-10 nm; thickness of both upper and lower anti-reflection layers is 10-100 nm; and thickness of both upper and lower anti-dazzle layers is 100-200 nm. specular reflectance of the glass is less than or equal to 0.1%, and visual resolution is greater than or equal to 8 lp / mm. The yield is high; product quality is stable; and the production process is environmentally-friendly and pollution-free.

Description

technical field [0001] The invention relates to glass, in particular to a low-reflection high-resolution glass. Background technique [0002] Glare is a kind of serious light pollution, which will cause the decline of visual functions such as contrast perception, vision and recognition speed of the eyes, and also affect people's emotions, making people dizzy and upset, loss of appetite, irritability, depression, physical fatigue, etc. Seriously interfere with and hinder people's normal life. As for the control of glare pollution, there are no clear regulations and standards at home and abroad. Therefore, in order to maintain people's visual health and improve labor efficiency, the protection of glare is particularly important, especially for display glass. [0003] The anti-reflection glass currently on the market can be divided into two categories according to different anti-reflection principles: one is that it forms a granular surface on the surface of the glass panel th...

AI Technical Summary

Problems solved by technology

[0004] Taking the ordinary alkali metal glass panel as an example, its light transmittance is usually about 89%, and its total reflectance is 8%. After the glass panel is etched by AG, its specular reflectance can be reduced to 3%. The light transmittance of the glass panel will not be greatly affected, and the light transmittance is usually around 89%. The disadvantage of this method is that the visual resolution of the glass is low, which cannot meet the needs of the flat panel display industry, and a large amount of Inorganic acid, great pollution to the surrounding environment

After AR coating treatment, the light transmittance is higher than 95%, and the specular reflectance can be reduced to about 2%. The disadvantage of this method is that the film layer is not firm, and the anti-reflection effect decreases rapidly when the external environment is harsh.
