1. A display device comprising:
at least one temperature sensor configured to detect a temperature information of a display panel;
a memory configured to store gamma sets and temperature correction lookup tables, the gamma sets include gamma reference voltages according to luminances and driving frequencies of images and the temperature correction lookup tables include offsets for correcting the gamma sets depending on the temperature information of a display panel;
a gamma set selector configured to select a gamma set according to a luminance and a driving frequency of an externally input image; and
a temperature corrector configured to select a temperature correction lookup table according to a result of detection of temperature information of the display panel displaying the image and to reflect an offset for each gamma tab stored in the temperature correction lookup table in a gamma reference voltage for each gamma tab stored in the gamma set to generate a corrected gamma set,
wherein the memory includes two or more temperature correction sets including a plurality of temperature correction lookup tables set for a plurality of reference temperatures, and different offsets are set for the same gamma tab at a same temperature in the temperature correction sets,
wherein the temperature corrector is configured to
select one of the temperature correction sets for each gamma tab and
correct the gamma reference voltage of corresponding gamma tab based on the temperature correction lookup table selected according to the temperature information of a display panel among the temperature correction lookup tables included in the temperature correction set,
wherein at least one of temperature correction sets set for respective gamma tabs of the gamma sets is different from temperature correction sets set for other gamma tabs.
