Abstract

The invention discloses a touch screen, a manufacturing method of the touch screen and a touch display device. A bridging layer of a touch structure of the touch screen is made of grephene, and due to the fact that the grephene has a high charge migration rate, and the resistance value in the visible light wave band has nothing to do with the light wave length, the grephene plays a very good bridging role on adjacent touch control drive electrodes or adjacent touch control induction electrodes in a touch control structure. In addition, compared with a bridging layer made of ITO materials in the prior art, the bridging layer made of grephene has a very high antistatic property. Compared with a bridging layer made of metal materials in the prior art, the defects of metal climbing and bridge point visibility can be overcome, and the transmittance of the touch screen can be improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen, a manufacturing method thereof and a touch display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in 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] At present, the single-chip (OGS, One Glass Solution) touch module that is widely used is to directly form a single-layer touch conductive film and sensor on the substrate, such as Figure 1a with ...
