Abstract:
A luminance control method of a display device is provided to control luminance of a display device. The display device has a display unit having a plurality of pixels emitting light. In some aspects, the luminance control method includes receiving a luminance level, applying a first luminance control method if the received luminance level is less than a reference luminance level, calculating an average value of video data for each frame if the luminance level is greater than the reference luminance level, applying the first luminance control method if the average value is less than a reference gray level value, and applying a second luminance control method if the average value is greater than the reference gray value level.
