Abstract
The invention discloses a grapheme conductive film applied capacitive screen and a manufacturing method thereof. The capacitive screen comprises a PET (polyethylene glycol terephthalate) substrate, a grapheme conductive film, solid-state optical cement and a glass cover. The PET substrate is bonded with the lower surface of the grapheme conductive film, and the upper surface of the grapheme conductive film is bonded with the glass cover through the solid-state optical cement. The grapheme conductive film applied capacitive screen has the advantages that the capacitive screen applied with the grapheme conductive film has excellent conductivity, permeability and the like as the grapheme conductive film with excellent conductivity, high optical permeability and durability is used for substituting for an indium tin oxide (ITO) conductive film on a capacitive screen sensor; the manner of producing the grapheme conductive film by means of chemical vapor deposition is superior to the manner of producing the ITO conductive film by means of magnetron sputtering in terms of complexity in preparation of raw materials, price, equipment input and adaptability to the market requirement.
