▎ 摘  要

NOVELTY - The method involves preparing (S1) a graphene layer on front and rear surfaces of a glass layer. The graphene layer on the front and rear surfaces of the glass layer is etched according to a predetermined pattern of a sensor (S2). The front surface of the graphene layer is provided with a cover layer (S3). A copper foil surface is formed on a grow single- layer graphene layer by utilizing a normal pressure cvd process. A thermal expansion tape is adhered on the copper foil surface. The thermal expansion tape is covered with the graphenel layer. The graphene layer is formed on the glass layer. USE - Full screen fingerprint identification capacitive touch screen manufacturing method. ADVANTAGE - The method enables realizing the touch screen to obtain fingerprint identification ability, obtaining a full screen fingerprint identification, and reducing manufacturing cost and volume of an electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a full screen fingerprint identification capacitive touch screen manufacturing method. '(Drawing includes non-English language text)' Step for preparing graphene layer on front and rear surfaces of glass layer (S1) Step for etching glass layer (S2) Step for providing graphene layer with cover layer (S3)
