▎ 摘  要

NOVELTY - The utility model claims a kind of graphene capacitive touch screen, a transparent conductive film of the touch screen is jointed by graphene thin film is two layers of different pattern direction. This utility model realizes the multi-point touch function a plurality of graphene capacitor touch screen, obviously reduces the production cost of the touch screen, avoiding in the processing process, the PET base material bending caused by the damage, avoiding complex, yellow process of high cost, in the process of forming the window touch sensing electrode pattern, a laser direct write etching a metal mask with reactive ion etching, the manufacturing process is convenient and fast and high efficiency.
