Abstract
One or more embodiments of the present disclosure provides a display device. The display device includes a display panel which includes a plurality of pixels; a threshold voltage sensing circuit which senses a threshold voltage of a light emitting diode included in the plurality of pixels, a data compensating circuit which corrects a data signal in accordance with a variation of the threshold voltage and accumulated data to generate a corrected data signal, and a data driver which generates a data voltage in accordance with the corrected data signal to output the data voltage to the display panel, in which the data compensating circuit periodically corrects the data signal in accordance with a look-up table in which a relationship of the variation of the threshold voltage and the accumulated data is described during an aging period to generate the corrected data signal. The display device according to the present disclosure improves an image quality of the display.
