Abstract

A compensation method of a display device includes: sensing a first luminance of the display device when a first pattern is displayed on the display device; calculating a luminance prediction value corresponding to a second pattern to be displayed on the display device based on the first luminance, where the second pattern is different from the first pattern; sensing a second luminance of the display device when the second pattern is displayed on the display device; adjusting a current flowing in a first power line of the display device until the second luminance reaches the luminance prediction value; and storing compensation data corresponding to an adjusted current in a lookup table when the second luminance reaches the luminance prediction value.
