Abstract
A display device includes a processor which supplies grayscale data in active periods of frame periods and stops supply of the grayscale data in blank periods of the frame periods, a timing controller which generates a change signal when a difference between a first blank period of a first frame period and a second blank period of a second frame period is greater than a threshold value, a power supply which supplies a first power voltage having a voltage level changed based on the change signal to a first power line, and pixels commonly connected to the first power line.
