Abstract
A display device includes: a display panel including a plurality of pixels; a sensing data memory configured to store sensing data for threshold voltages of driving transistors of the plurality of pixels; a controller configured to determine a total threshold voltage shift amount for the driving transistors of the plurality of pixels based on the sensing data, to determine total luminance data based on input image data, to determine a frame stress based on the total luminance data and the total threshold voltage shift amount, to determine a target compensation voltage level based on the frame stress, and to generate compensated image data by compensating the input image data based on the target compensation voltage level; and a data driver configured to provide data voltages to the plurality of pixels based on the compensated image data.
