Capacitive touch screen and manufacturing method thereof

Abstract

The invention discloses a capacitive touch screen and a manufacturing method thereof. A bridging jumper wire comprises two groups of line conductor transparent conductive films, an insulating film and a metallic bridging film layer which are arranged on a base plate; the first group of line conductor transparent conductive films are arranged continuously, and the second group of line conductor transparent conductive films are arranged sectionally by taking the first group of line conductor transparent conductive films as spacers; the insulating film covers the first group of line conductor transparent conductive films and the adjacent base plate surface at the intersection of two groups of line conductors; the metallic bridging film crosses over the insulating film to connect the second group of line conductor transparent conductive films arranged at intervals as a continuous body and covers the surface of the base plate. The method comprises the steps of: manufacturing two groups of line conductor conductive files, and manufacturing the insulating film and manufacturing the metallic bridging film. In the invention, the transparent conductive films of two groups of line conductors can be manufactured at the same time, thereby avoiding chromatic aberration and improving the quality of the touch screen; the margin of the insulating film is located on the base plate, and the metallic bridging film layer can not be broken, thereby improving the yield of the product; the metallic bridging film layer is thick and not easy to be broken; and the metallic bridging film layer has small wire resistance, thereby improving the performance of the touch screen.

Description

technical field [0001] The invention relates to a touch screen wiring, and also relates to a manufacturing method of the touch screen wiring, in particular to a capacitive touch screen and a manufacturing method thereof. Background technique [0002] The wiring of the touch screen includes two sets of wires crossing in the X direction and the Y direction. The existing touch screen wiring structure has the following defects: [0003] 1. The two groups of wires in the X direction and the Y direction intersect in space. In the manufacturing process, it is necessary to make a bottom group of conductive films first, then make an insulating film, and then make an upper group of conductive films. Since the transparent conductive films of the two sets of wires must be made separately, it will cause color differences between the two layers of conductive films and reduce the product quality of the touch screen; [0004] 2. Since the conductive film material of the wire is made of tra...

AI Technical Summary

Problems solved by technology

Since the transparent conductive films of the two sets of wires must be made separately, it will cause color differences between the two layers of conductive films and reduce the product quality of the touch screen;

[0004] 2. Since the conductive film material of the wire is made of transparent material, the film layer is relatively thin, and the bridging film layer above the intersection point of the two sets of wires is prone to disconnection, resulting in partial wire disconnection;

[0005] 3. The conductive film wire resistance of the wire is high, which reduces the performance of the touch screen
