Wiring and manufacturing method of capacitive touch screen

Abstract

The invention relates to a wiring structure of a capacitive touch screen and a manufacturing method thereof, wherein the wiring structure comprises two groups of transparent conducting films on X and Y directions on a substrate, an insulating film and a connecting film, wherein the surface resistance of the connecting film is lower than the surface resistance of the transparent conducting films, an intersection structure of the transparent conducting films on the two directions adopts continuous connection or tunnel connection, wherein the continuous connection structure is a continuation of transparent conducting film materials at two sides of the intersection point, and the tunnel connection structure is achieved as follows: the transparent conducting film on X or Y direction is continuously connected at the intersection point, and the transparent conducting film on the other direction is disconnected; the connecting film is sectionally arranged corresponding to the disconnected transparent conducting films at the intersection point; the insulating film is covered at the middle part of the connecting film, the disconnected transparent conducting films are covered at the end part of the connecting film and the substrate to form a continuous wire, and the transparent conducting films which are continuously connected at the intersection point stretch over the connecting film to be covered on the insulating film and the substrate. The manufacturing method comprises the step of manufacturing the connecting film, the insulating film and two groups of wire conducting films. The invention can avoid color difference and improve the sensitivity, the standard ratio and the quality of the touch screen.

Description

technical field [0001] The present invention relates to a wiring structure of a touch screen and a manufacturing method of the wiring structure of the touch screen, in particular to a wiring structure of 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 conduc...

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 tunnel film layer above the intersection point of the two sets of wires is prone to disconnection, resulting in partial wire disconnection of the wire and reducing the product yield;

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