NOVELTY - The utility model claims a pressure sensing capacitor type composite touch screen, comprising a substrate, a controller, a first graphene film, the second graphene film, PVDF film, adhesive and electrode, the substrate and the first graphene film, viscose, the second graphene membrane and PVDF transparent film are fixedly stacked, the electrodes are respectively connected at two sides of two side and the second graphene film first graphene film, the controller is connected with the electrode. The utility model through the graphene and piezoelectric material PVDF thin film composite, which can form a pressure sensing signal is stronger, higher sensitivity of the pressure sensor system 3D-touch.
