Abstract

The invention provides a manufacturing method for a capacitive touch screen coated with a GF2 structure. The method sequentially comprises the following steps: step A, forming a first transparent conductive layer, a transparent conductive pattern and a first bezel winding; step B, forming a second transparent conductive layer and a transparent conductive layer pattern; step C, printing a conductive material in a bezel region of a second surface of a base material layer to form a second bezel winding; and step D, laminating glass and a display screen. Compared with conventional GF2 production, the manufacturing method for the touch screen has the advantages that the transparent conductive layer of the second surface is formed by coating after finishing the transparent conductive pattern and the winding of a first surface, so that a manufacturing process is simplified, a process of forming conductive patterns on two surfaces of the same substrate can be easily realized, more manufacturing processes (such as laser engraving and the like) can be compatible, the production cost is greatly reduced, and the yield is increased.

Description

Technical field [0001] The present invention relates to the technical field of touch screens, and in particular to a capacitive touch screen with a post-coated GF2 structure and a manufacturing method thereof. Background technique [0002] The touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connection devices according to pre-programmed programs, which can be used to replace mechanical -Style button panel, and through the liquid crystal display screen to create dynamic audio and video effects. [0003] In the current touch screen field, capacitive touch screens are widely used due to their high precision. The main structures of capacitive touch screens include GFF (Glass-Film-Film), G1F (Glass-Film), GG (Glass-Glass), G2 (GlassOnly), GF2, among which GG and G2 are used in glass The method of sputtering ITO patt...
