1. A display device comprising:
a touch sensing unit on a front surface of an image display area and configured to sense a location of a touch;
a display driver circuit configured to select one of first to third temperature sensing modes during a predetermined temperature sensing period and to generate at least one of first to third mode sensing control signals according to the selected temperature sensing mode; and
a touch driver circuit configured to generate at least one of first to third temperature sensing map data in response to at least one of the first to third mode sensing control signals,
wherein the display driver circuit is configured to compensate for image data based on at least one of the first to third temperature sensing map data and to display an image according to the compensated image data in the image display area,
wherein the first temperature sensing map data is based on signals corresponding to driving electrodes and sensing electrodes arranged in the touch sensing unit,
wherein the second temperature sensing map data is based on signals corresponding to gate or data lines of the image display area and driving electrodes or sensing electrodes arranged in the touch sensing unit, and
wherein the third temperature sensing map data is generated according to an average of accumulated values of the first and second temperature sensing map data.
