Abstract:
1. A display device comprising: a display unit including a plurality of pixels, each of which emits light according to each of a plurality of data voltages; a timing controller which divides an area of the display unit into an upper portion, a center portion and a bottom portion, divides one frame time into a plurality of sub-frames including a plurality of light emission sub-frames of a light emission period and a blank sub-frame of a blank period in which a black data signal is supplied, and generates an image data signal corresponding to each of the plurality of sub-frames; and a data driver which applies a data voltage corresponding to the image data signal to the display unit, wherein the timing controller divides the upper portion into at least three groups including first to third groups, the center portion into at least four groups including fourth to seventh groups, and the bottom portion into at least three groups including eighth to tenth groups, and 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 of a group of the first to the tenth groups and decrease the blank period of the group of the first to the tenth groups in proportion to an increase ratio of the light emission period as the group of the first to the tenth groups is closer to a middle of the center portion.
