Capacitance touch screen and method for preparing the same

Abstract

Capacitance touch screen and method for preparing the same, the touch screen includes a substrate, two sets of wire transparent conductive films, an insulation film, and two sets of low-resistance conductive film, two sets of transparent conductive films are disposed sectionally in interval and two sets of transparent conductive films are coincided corresponding to each other at every interval position; a first low-resistance conductive film connects with its transparent conductive film along direction of the first set of wires to form a continous set of wires, a second low-resistance conductive film crosses the first low-resistance conductive film along direction of the second set of wires to connect its transparent conductive film to form a second continous set of wires. An insulation film is disposed between two sets of low-resistance conductive films and covers surface of substrate adjacent to the first set of low-resistance conductive film, the second low-resistance conductive film covers the insulation film. The method produces the first, second set of transparent conductive films, an insulation film and low-resistance conductive film on the substrate step by step to implement the touch screen structure. The wires according to the invention are not easy to break which reduces resistance of wires, reduces chromatic aberration and electrical interference, and improves performance and quality of products.

Description

technical field

[0001] The present invention relates to a touch screen and a manufacturing method of the touch screen, in particular to a capacitive touch screen and a manufacturing method thereof. Background technique

[0002] The capacitive touch screen includes two sets of wires that cross in the X direction and the Y direction. The existing wire wiring structure of the capacitive touch screen has the following defects:

[0003] 1. 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 local wire disconnection;

[0004] 2. The conductive film wire resistance of the wire is high, which reduces the performance of the touch screen;

[0005] 3. The parasitic capacitance in the X and Y directions is large, and the noise reduction performance is poor, which reduces the sensitivity and resolution of...
