Abstract
A display device includes a memory configured to store gamma sets set for luminances and driving frequencies of images and temperature correction lookup tables set for temperatures, 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 a 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.

A display device comprising:
- a memory configured to store gamma sets set for luminances and driving frequencies of images and temperature correction lookup tables set for temperatures;
- 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 a 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.
A method of driving a display device, comprising:
- storing gamma sets set for luminances and driving frequencies of images and temperature correction lookup tables set for temperatures;
- selecting a gamma set according to a luminance and a driving frequency of an externally input image;
- selecting a temperature correction lookup table according to a result of detection of temperature information of a display panel displaying the image;
- and
- reflecting an offset of a gamma reference voltage for each gamma tab stored in the temperature correction lookup table in the gamma reference voltage for each gamma tab stored in the gamma set to generate a corrected gamma set.
