Abstract
Disclosed is an integrated graphene film-enhanced display device, comprising: (a) a display device which comprises one or multiple heat sources and a back surface where a localized area is at a higher temperature than an adjacent area; and (b) a heat spreader which comprises at least one sheet of integrated graphene film having two major surfaces, wherein one of the major surfaces of the heat spreader is in thermal contact with one or multiple heat sources and further wherein the heat spreader itself reduces the temperature difference between locations on the display device. The integrated graphene film, either a graphene film obtained from a graphene oxide gel or a graphene composite film formed of graphene oxide gel-bonded nano graphene platelets (NGPs), exhibits highest thermal conductivity and highest effectiveness in reducing hot spots in various kinds of display devices.
