NOVELTY - The utility model claims a mutual capacitance touch screen function piece, the mutual capacitance touch screen function sheet structure comprising a base film, IT0 a driving layer provided on the substrate film is provided on the ITO drive layer of the isolation layer. graphene sensing layer set on the ITO drive layer and the protective glue layer set on the graphene sense layer, the ITO drive layer is a patterned ITO film, the graphene sense layer is graphene film driven by patterning the IT0 layer and the graphene sense layer are connected through lead is connected with the capacitance induction chip. The utility model method under the premise of ensuring the marking effect, can greatly reduce the mutual capacitance touch screen function whole thickness, finished product marking effect and double-layer single-sided ITO structure effect under the same condition, but the thickness is only 1/3.
