Embodiment 1

[0043] An embodiment of the present invention provides a touch electrode, and the material of the touch electrode includes doped graphene. Among them, the doped material in doped graphene can increase the concentration of charges in the touch electrodes, so that the conductivity of the touch electrodes increases, and because the conductivity is inversely proportional to the size of the sheet resistance, it can reduce the density of the touch electrodes. The square resistance improves the sensitivity of the touch screen. For example, when the light transmittance of the touch electrodes is the same, the sheet resistance of the touch electrodes made of graphene is 120Ω, and the sheet resistance of the touch electrodes made of doped graphene is less than 10Ω.

[0044] Specifically, the doped material for doping graphene can be one or both of aluminum chloride and zinc iodide, or other materials that can increase the charge concentration in the touch electrode without reducing the ...

Abstract

The embodiment of the invention discloses a touch electrode, a touch electrode manufacturing method, a touch screen and a display device, and relates to the technical field of display. Square resistance of the touch electrode can be reduced, and therefore sensitivity of the touch screen can be improved. The material of the touch electrode comprises doped graphene.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch electrode and a manufacturing method thereof, a touch screen, and a display device. Background technique [0002] Usually, the display device includes a touch screen, so that the display device can be operated only by touching the display screen of the display device without installing a mechanical button panel. Wherein, the touch screen includes touch electrodes, and common touch electrodes are made of indium tin oxide and metal mesh. [0003] The inventors found that when using the above-mentioned materials to make touch electrodes, the square resistance of the touch electrodes is high, which makes the sensitivity of the touch screen lower, so the user needs to touch the display screen multiple times to operate the display device, thereby reducing the The service life of the touch screen, and the user experience is poor. Contents of the invention [0004] T...
