▎ 摘  要

NOVELTY - The screen has a touch module jointed with a display module (7). The touch module is provided with a glass cover (1), a graphite conductive layer (3) and an indium tin oxide conductive layer (5). The graphene conductive layer is adhered with the indium tin oxide conducting layer. The graphene conductive layer is distributed with a drive line for providing a driving signal. The indium tin oxide conducting layer is provided with a detecting line for providing a capacitive coupling signal. The graphene conductive layer is connected with the Indium Tin Oxide conducting layer through an OCA glue (4). USE - Graphene capacitor touch screen. ADVANTAGE - The screen uses the graphene as the driving line for supplying drive signals and reduces using amount of ITO so as to reduce toxicity of the touch screen, and is helpful for using and improves transmittance and the operation sensitivity of the capacitance touch screen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene capacitor touch screen manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene capacitor touch screen.
