Capacitance type touch screen and manufacturing method thereof

Abstract

The invention relates to a capacitance type touch screen and a manufacturing method thereof. The capacitance type touch screen comprises a substrate, two sets of transparent conducting films of conducting wires, an insulating film and a metal bridging beam film. In the two sets of conducting wires, the first set of transparent conducting films are continuously arranged, and the second set of transparent conducting films are piecewise arranged by using the transparent conducting films of the first set as intervals. The insulating film covers the surfaces of the two sets of transparent conducting films, and the insulating film above each film section of the second set of transparent conducting films comprises a through hole. The metal bridging film is attached on the insulating film, crosses the first set of transparent conducting films and is connected with the second set of transparent conducting films which are arranged at intervals on both sides of the first set of transparent conducting films by passing through the through hole on the insulating film so as to form the continuous second conducting wires. The method comprises the following steps: manufacturing the first set of transparent conducting films, the second set of transparent conducting films, the insulating film and the metal bridging film to achieve the structure of the touch screen. The invention adopts the metal bridging film, thereby improving the continuity of the second set of conducting wires, reducing the resistance of the second set of conducting wires and the color difference of the touch screen and improving the performance of the touch screen and the product quality.

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 wire resistance of the conductive film is high, which reduces the performance of the touch screen; [0005] 3. Two groups of wires in the X direction and Y direction intersect in space. In the manufacturing process, it is necessary to make a bottom group of conductive f...

Problems solved by technology

[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 wire resistance of the conductive film is high, which reduces the performance of the touch screen;

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;

[0006] 4. Due to the lack of shielding structure of the touch screen, the touch screen cannot shield the electrical interference from the display device, which affects the performance of the touch screen
