Thermally conductive poled damping assembly
A portable information handling system integrates a display film having OLED pixels to a housing with a graphene foam having graphene particles disposed in an intermediary material with varied orientations that promote thermal transfer from the display film. For example, graphene particles disposed in a silicon resin to form the foam couples between a portable housing and a display film to transfer thermal energy to the portable housing from the display film.
