Abstract: A display device includes: a plurality of pixels coupled to data lines and sensing lines; a data driver configured to supply one of an image data signal and a sensing data signal to the data lines; a voltage supply configured to supply an initialization voltage to the pixels through the sensing lines; and a sensing circuit configured to receive a sensing value from at least one of the pixels through the sensing lines, and compare the sensing value with a sensing reference value to generate a sensing voltage control signal to control at least one of the sensing data signal or the initialization voltage.
