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.
