A display device is disclosed that includes a display panel having pixels configured to display images during a first frame, a second frame, and a third frame, each of the first frame, the second frame, and the third frame including an active period and a blanking period; a counting circuit configured to count a duration of the blanking period of the first frame after the active period of the first frame; a comparison circuit configured to compare the counted duration of the blanking period of the first frame with a threshold time required for sensing at least one pixel or a threshold time required to prepare for driving the pixels during the second frame; and a delay decision circuit configured to determine whether to increase a duration of the blanking period of the first frame based on the comparison.
