Problems solved by technology

Since the material of the shielding layer 02 contains a resin material, when the base substrate 01 formed with the shielding layer 02 is bombarded by plasma (plasma) in the sputtering chamber, other substances will be released, thus contaminating the chamber
In addition, when the plasma bombards the surface of the shielding layer 02, it will also cause uneven defects such as protrusions and depressions on the surface of the shielding layer 02, which will affect the flatness of the subsequent film layer and cause problems such as poor craftsmanship.

Abstract

The invention discloses a touch screen, a touch screen manufacturing method and a display device. Since a touch structure and peripheral lines are positioned on one side of a substrate while a shielding layer is positioned on the other side of the substrate, namely the shielding layer and the touch structure are positioned on two sides of the substrate respectively, when the touch structure and the peripheral lines are made on the substrate of the touch screen by means of sputtering, and the shielding layer on the other side of the substrate can be protected from strafing of plasmas in a sputtering cavity so as to be prevented from contaminating the cavity. In addition, due to the fact that the shielding layer is positioned on the other side of the substrate, compared with the prior art in which the touch structure and the peripheral lines are formed on a film layer of the shielding layer, the touch screen, the touch screen manufacturing method and the display device have the advantages that the problem of unevenness of the touch structure resulted from unevenness of the shielding layer is avoided, and quality of the touch screen is guaranteed.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen, a manufacturing method and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread throughout people's lives. At present, touch screens can be divided into: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, vibration induction, and frustrated total internal reflection optical induction, etc. according to their working principles. Among them, the capacitive touch screen is sought after by the industry as a new favorite due to its unique touch principle, high sensitivity, long life, high light transmittance and other advantages. [0003] The single-chip (OGS, One Glass Solution) touch module that is widely used at present is to directly form a single-layer touch conductive film and sensor on the substrate, such as Figure 1a with Figure ...
