Manufacturing method for anti-glare (AG) panel display glass

Abstract

The invention provides a manufacturing method for AG panel display glass, belonging to the technical field of deep processing of glass. An automatic AG panel display glass production line is adopted in the invention. The manufacturing method comprises the following process flow: feeding; pickling; etching; turnover of panels; washing; thinning and polishing; washing and drying through sucking; and air drying. Through pickling, impurities adhered on the surface of a glass flake can be cleaned, so a clean glass surface is obtained for acid etching. Through corrosion of strong acid, honeycomb corrosion pits are formed in the surface of glass, so surface roughness of glass is improved. Chemical polishing is employed for fine processing control of the acid etched surface of the AG glass, and a DCS control system is used for realization of automatic operation of whole flow; thus, accurate control of technological parameters is realized, and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to an AG anti-glare flat panel display glass manufacturing method. Background technique [0002] Anti-glare glass, also known as non-reflective glass or anti-reflective glass, is a special surface treatment of the glass substrate, so that it has a lower reflectance than ordinary glass, and basically does not affect the transmission of light. From 8% to below 1%. Anti-glare glass can improve the viewing angle and brightness of the display screen, making the image clearer, the color more vivid, and the color more saturated, thereby significantly improving the display effect. It can be widely used in the production of LCD screens, rear projection TVs, education machine screens, mobile phone covers, electronic photo frames, and instrument display panels. [0003] AG anti-glare substrate glass is an important basic component of a new flat panel display device, and its opt...

AI Technical Summary

Problems solved by technology

The whole process of glass etching connects each work area through a conveyor belt. When preparing AG glass, each work area can only be processed by a single machine, and there is no work area for process adjustment. The automatic control device for the etching time and speed of AG anti-glare glass acid cannot achieve etching. Process fine management and control

Especially after acid etching, the equipment only undergoes repeated brushing, water washing, blot-drying and blow-drying, and does not apply chemical polishing technology for subsequent processing of the etched surface, and does not change the etching state of the etched surface

It can be seen that the etched surface of AG glass prepared by this production equipment must be rough and uncontrollable artificially, and the target product that meets the optical performance requirements of AG glass cannot be produced.
