Abstract: A display device includes a display panel including pixels; a sensor configured to generate sensing data by measuring a current flowing through each of the pixels based on a reference voltage; and a compensator to generate stress data by calculating stress of the pixels based on input data provided from an external component and to generate degradation data by compensating a variation of the sensing data based on the stress data.
