Industrial control LCD display panel coating process and cleaning method thereof

Abstract

The invention discloses an industrial control LCD display panel coating process and a cleaning method thereof. The process and the cleaning method are characterized in that the process comprises the steps of air hole plugging, surface treatment, polishing, cleaning, drying and coating; the residual liquid crystal in a liquid crystal display screen is removed in the coating process, so that the coating effect is prevented from being affected, the panel coating process and the cleaning method thereof are not interfered with the treatment process in sequence, and it is guaranteed that imaging ofthe liquid crystal display screen is not affected; compared with the prior art, when liquid crystal on the surface of the liquid crystal screen is removed, the strength of the liquid crystal screen isfurther enhanced, the impact resistance of the liquid crystal screen is improved, and the situation that the liquid crystal screen is broken due to collision is reduced; a cleaning agent is adopted for cleaning the surface of the display screen, the dirt-removing power is high, the cleaning effect is better, glass of the liquid crystal display screen cannot be corroded, and re-sedimentation of metal ions on a cleaned object is prevented by adding a chelating agent.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an industrial control LCD display panel coating process and a cleaning method thereof. Background technique [0002] Liquid crystal display A type of display used in digital clocks and many portable computers that uses two sheets of polarized material with a liquid crystal solution between them, through which current passes to rearrange the crystals so that Light cannot pass through them. Therefore, each crystal is like a shutter, which can not only allow light to pass through but also block light. LCD monitors are currently developing towards the goal of light, thin, short, and small; whether it is a right-angle display , low power consumption, small size, and zero radiation, etc., can allow users to enjoy the best visual environment. The use of liquid crystal displays is becoming more and more extensive; , a series of treatments are required on its surface. However, in...

[0002] Liquid crystal display A type of display used in digital clocks and many portable computers that uses two sheets of polarized material with a liquid crystal solution between them, through which current passes to rearrange the crystals so that Light cannot pass through them. Therefore, each crystal is like a shutter, which can not only allow light to pass through but also block light. LCD monitors are currently developing towards the goal of light, thin, short, and small; whether it is a right-angle display , low power consumption, small size, and zero radiation, etc., can allow users to enjoy the best visual environment. The use of liquid crystal displays is becoming more and more extensive; , a series of treatments are required on its surface. However, in the prior art, a lot of liquid crystals will remain in the liquid crystal screen during the production process of the liquid crystal display. And its cleaning method has a great impact, so we provide an industrial control LCD display panel coating process and its cleaning method to solve the problems raised in the above-mentioned background technology
