Drive controller, display device, and method for driving display device

A drive controller for driving a plurality of pixels, the drive controller comprising:

• a heat emitting controller,
• wherein the heat emitting controller includes:
• an average region setter configured to receive an 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 heat emitted from each of the plurality of pixels and varied depending on the image signal.

A method for driving a display device, the method comprising:

• providing an image signal to a drive controller to drive a display panel including a plurality of pixels;
• setting, to one pixel region, some pixels of the plurality of pixels;
• extracting 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;
• substituting a diffusion region set to have a temperature corresponding to the average gray level into the average region;
• and
• generating a look-up table map by predicting heat which is emitted from each of the plurality of pixels and varied depending on the image signal.
