NOVELTY - The utility model relates to the technical field of electronic device, specifically to a protective film, and electronic device for glass screen. the protective film comprises a first adhesive layer for bonding on the glass screen, a protective layer over the first adhesive layer, and a graphene layer between the first adhesive layer and protection layer, the graphene layer adjacent to the first adhesive layer. thermal conductivity of graphene layer is high, the heat of the heating region of the glass more intensively on the screen can be quickly transmitted to the outer surface of the protection film by the graphene, and is uniformly diffused to the whole surface of the protective film, the increasing of the external heat exchange area, improve heat dissipation speed and radiating ability. and the protective layer has a scratch resistant and wear resistant properties. To sum up, the protection film of the utility model also has good heat dissipation while providing protection for the glass screen, which can ensure the adhered with the glass screen of the protective film has low surface temperature, improve the user experience and prolongs the service life of the electronic device.
