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.

A method of driving a display panel includes comparing a previous line data and a present line data to generate a charge sharing enable (EQ) signal indicating whether or not a charge sharing is to be applied to a pixel; selectively applying the charge sharing to the present line data utilizing a charge sharing voltage according to the EQ signal to generate a data voltage; and outputting the data voltage to the pixel.

A temperature of a display is evaluated from the image displayed. The device may be tested with various images or with various test patterns in order to obtain the heat generation response related to the image. For example, a bright image may generate more heat than a dark image. The heat generation response behavior is stored into a device memory. A heat radiation response behavior is also obtained with various test patterns. The display temperature is estimated using an image to be displayed with the predetermined heat generation and heat radiation responses. The ambient temperature may be used to improve the estimation.
