Abstract
A display device includes a display unit including pixels, each of which emits light according to data voltages, respectively; and a timing controller which divides an area of the display unit into an upper, center and bottom portions, divides one frame time into light emission sub-frames of a light emission period and a blank sub-frame of a blank period in which is supplied a black data signal, divides the upper, center and the bottom portions into groups, differentiates a scan start time of a light emission sub-frame and a scan start time of the blank sub-frame of each group, and increases the light emission period and decreases the blank period in proportional to an increase ratio of the light emission period as a group is closer to a middle of the center portion.
