Abstract: Provided is an optical compensation method for a display device including a pixel coupled between first power and second power sources. In the optical compensation method, the first voltage level of the second power source corresponding to a first luminance level is set while measuring the luminance of the display device, the second voltage level of the second power source corresponding to a second luminance level is set while measuring the luminance of the display device, the third voltage levels of the second power source for representative luminance levels including the first and second luminance levels are set based on the first and second voltage levels, and the fourth voltage levels of the second power source for the representative luminance levels according to temperature conditions are set based on the third voltage levels and temperature offsets according to the temperature conditions, under which the display device is driven.

Abstract: A display device a display driver configured to drive pixels in correspondence with input image data, timing signals, and a brightness selection signal. The display driver includes a storage unit configured to store gamma data and a duty value for each of a plurality of sample brightness levels including a K-th sample brightness level, and a brightness controller the display driver being configured to control the brightness of the display area according to the gamma data or the duty value or gamma data obtained by non-linearly interpolating gamma data of a (K−1)-th sample brightness level and the K-th sample brightness level, with respect to a tuning point brightness level. A light emission time of the pixels corresponding to the (K−1)-th sample brightness level is less than or equal to 10% shorter than the light emission time of the pixels corresponding to the K-th sample brightness level.
