Abstract
A display device includes a display panel including pixels each including a light emitting element and a bypass transistor connected to the light emitting element to receive an initialization voltage, a first offset voltage determining unit determining a first offset voltage using a brightness period of image data and a temperature of the display panel, a black image detecting unit detecting black data among the image data to determine a dense area of the pixels to which the black data are applied, and determining whether to proceed with a subsequent operation, an image analyzing unit analyzing the image data depending on the determination of whether to proceed with the subsequent operation, and outputting an analyzed result, and a second offset voltage determining unit determining a second offset voltage using the analyzed result. The initialization voltage is determined using the first offset voltage and the second offset voltage.
