1. A display device comprising:
a display panel including a plurality of pixels and configured to display an image; and
a drive controller configured to receive an image signal, and to drive the plurality of pixels, and including a heat emitting controller,
wherein the heat emitting controller includes:
an average region setter configured to receive the image signal, to set, to one pixel region, some pixels of the plurality of pixels, and to extract an average gray level, based on gray levels of the some pixels of the plurality of pixels to set an average region from the pixel region;
a diffusion region setter configured to substitute a diffusion region, which is set to have a temperature corresponding to the average gray level, into the average region; and
a look-up table map generator configured to generate a look-up table map by predicting, based on the diffusion region, heat emitted from an inner part of a display region of the display panel and varied depending on the image.
