▎ 摘　　要

NOVELTY - The touch screen device has a layered structure that is provided with a protective layer (1), ferroelectric polymer layers, multi-layer graphene layer and a substrate layer. The multi-layer graphene is made by chemical vapor deposition. The sheet resistance of the layered structure is maintained to a certain ohms per Square. The polymer layers are fully polarized, partially polarized, or unpolarized. The touch by a touching object on a layered graphene-ferroelectric polymer touch screen is sensed by the crosspoints formed from placement of the first graphene-based electrode perpendicular to the second graphene-based electrode or mapped to the sensing crosspoint locations on the touch screen. USE - Touch screen device with graphene electrodes, used in touch panels and display screen applications. ADVANTAGE - The sense of reality of human-computer interaction is realized. The sheet resistance of the layered structure is maintained. The sheet resistance of graphene is decreased. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the mutual capacitance layered graphene-ferroelectric polymer touch screen.
