Problems solved by technology

Patent Publication No. CN 105524563A discloses a blue light blocking anti-glare optical film and its preparation method. This method can produce an optical film with anti-glare effect, but this film needs to add a new structure for display when it is used. Affect the light transmittance and display effect of the screen; in addition, because the film layer does not have strong structural strength and hardness, it is easy to be damaged when it is attached to the outer layer of the display screen, affecting performance

Embodiment 1

[0022] (1) Glass pretreatment: Cut the soda-lime glass with a precision cutter, the thickness of the soda-lime glass is 0.3mm, then send the glass into the grinder for chamfering and edging, and finally send the ground glass into Carry out pickling and deionized water washing in a cleaning machine, the pickling solution is hydrochloric acid, and drying is carried out after washing to obtain the desired glass.

[0023] (2) Physical strengthening of glass: Put the pretreated glass into a preheating furnace at 210°C, raise the temperature to 320°C within 60 minutes, then raise the temperature to 390°C within 40 minutes, and finally raise the temperature to 420°C within 70 minutes. After the heat treatment is completed, the tempering furnace is treated at a high temperature for 5 hours at a temperature of 420°C, and then the glass is sent to the annealing furnace, and the temperature drops to 100°C within 170 minutes for annealing treatment to obtain a strengthened glass. The annea...

[0027] (1) Glass pretreatment: Cut the soda-lime glass with a precision cutter. The thickness of the soda-lime glass is 0.8mm, then send the glass into the grinder for chamfering and edging, and finally send the ground glass into Carry out pickling and deionized water washing in a cleaning machine, the pickling solution is hydrochloric acid, and drying is carried out after washing to obtain the desired glass.

[0028] (2) Physical strengthening of glass: Put the pretreated glass into a preheating furnace at 180°C, raise the temperature to 280°C within 50 minutes, then raise the temperature to 370°C within 20 minutes, and finally raise the temperature to 400°C within 50 minutes. After the heat treatment is completed, the tempering furnace is treated at a high temperature for 3 hours at a temperature of 400°C, and then the glass is sent to the annealing furnace, and the temperature is lowered to 90°C within 150 minutes for annealing treatment to obtain a strengthened glass. The a...

[0032] (1) Glass pretreatment: Cut the soda-lime glass with a precision cutter, the thickness of the soda-lime glass is 0.5mm, then send the glass into the grinder for chamfering and edging, and finally send the ground glass into Carry out pickling and deionized water washing in a cleaning machine, the pickling solution is hydrochloric acid, and drying is carried out after washing to obtain the desired glass.

[0033] (2) Physical strengthening of glass: Put the pretreated glass into a preheating furnace at 210°C, raise the temperature to 300°C within 55 minutes, then raise the temperature to 380°C within 30 minutes, and finally raise the temperature to 410°C within 60 minutes. After the heat treatment is completed, the tempering furnace is treated at a high temperature for 4 hours at a temperature of 410°C, and then the glass is sent to the annealing furnace, and the temperature drops to 95°C within 160 minutes for annealing treatment to obtain a strengthened glass. The anneal...

Abstract

The invention belongs to the technical field of liquid crystal display, and specifically relates to a method for manufacturing an anti-glare liquid crystal glass cover plate; including the following manufacturing steps: (1) glass pretreatment, (2) glass physical strengthening, (3) coating pretreatment, (4) ) anti-glare coating. The process provided by the invention firstly cuts and grinds the glass, processes the glass into the required size, then heats the glass to improve the physical properties of the glass, increases the hardness and transparency of the glass, and finally evaporates the coating on the glass surface The way to get a layer of anti-glare film. The liquid crystal glass cover plate produced by the invention has the characteristics of high hardness, wear resistance and scratch resistance, and has good performance of filtering blue light and preventing glare.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a method for manufacturing an anti-glare liquid crystal glass cover plate. Background technique [0002] Liquid crystal display is a flat and thin display device, which is an important part of computer system. The structure of the liquid crystal display includes a backlight module, a polarizer, a thin film transistor, a liquid crystal, a color filter, etc. The uppermost layer of the display screen used by the user is a liquid crystal glass cover, and the liquid crystal glass cover is generally bonded by seamless bonding technology On the top of the LCD screen, it can play the role of including the liquid crystal display module. The more famous ones are the gorilla series glass of Corning Company of the United States and the sapphire glass of China Lens Technology. Strong impact force, good wear resistance and scratch resistance, users do not need to at...
