Abstract
A display device including pixels; a controller configured to generate first compensation data based on first sensing data with respect to threshold voltages of driving transistors of the pixels which are sensed during a first sensing period, to generate second compensation data based on second sensing data with respect to mobilities of the driving transistors of the pixels which are sensed during the first sensing period, to generate third compensation data based on third sensing data with respect to mobility change amounts of the driving transistors of the pixels which are sensed using image data for sensing compensated based on the first and second compensation data during a second sensing period, and to compensate input image data based on the first, second, and third compensation data to generate compensated image data; and a data driver configured to provide data voltages to the pixels based on the compensated image data.
