Embodiment Construction

[0017] The following combination figure 1 Specific embodiments of the present invention are described in detail.

[0018] First, take a certain concentration of chemical etching solution, the temperature is above 20°C, pour it into the etching container 1, the depth is enough to immerse the liquid crystal glass panels 2, and then fix a group of liquid crystal glass panels 2 on a tray 3 upright, the The tray is placed on the import bracket 4, and the import bracket is movably installed in the etching container 1, and there is a certain gap between each liquid crystal glass panel, so that the liquid medicine can flow therein. The lead-in bracket 4 moves downward to completely immerse the liquid crystal glass panel in the chemical etching solution 5, and then the group of liquid crystal glass panels moves forward on the conveyor belt 6 installed in the etching container for etching. When it moves to the lead-out bracket 7 at the other end of the conveyor belt at a specified spee...

Abstract

The invention discloses an etching method for a liquid crystal glass panel, relates to the technical field of liquid crystal panel display, in particular to the technical field of etching of a liquid crystal glass panel. The method mainly solves the problems that for the liquid crystal panel, the etching thickness is not uniform, and the etching efficiency is low. The technical problems are solved by the following technical scheme that the etching method for the liquid crystal panel comprises the following steps: firstly filling liquid: injecting chemical etching liquid into an etching container; secondly, guiding into the liquid crystal glass panel: vertically fixing a group of liquid crystal glass panels on a tray, arranging the tray on a guiding support, and moving the guiding support downwards, thereby dipping the liquid crystal glass panel completely by the chemical etching liquid; thirdly, etching, etching the surfaces of the guided liquid crystal glass panels by the chemical etching liquid; and fourthly, guiding out the liquid crystal glass panels: ejecting out the liquid crystal glass panels by a guiding-out support. The method is applicable to the etching on any liquid crystal glass panel.

Description

[0001] technical field [0002] The invention relates to the technical field of liquid crystal display, in particular to an etching method of a liquid crystal glass panel. Background technique [0003] Liquid crystal glass panels are widely used as display components of mobile phones, computers, televisions and other products, and are used more and more widely. The liquid crystal glass panel must be etched to form an array substrate. After further production, it can be used as a display component of mobile phones, computers, TVs and other products. At present, the etching technologies for liquid crystal glass panels mainly include wet etching and dry etching. Wet etching is to use the chemical reaction between a specific solution and the film to remove the part of the film that is not covered by the photoresist, so as to achieve the purpose of etching. The process can be divided into three steps: first, the chemical etching solution diffuses to the to-be-treated The surfac...
