Abstract: A display device can include a display panel including a plurality of pixels, a data driver configured to apply a reference data voltage to the display panel in a sensing mode, a current sensor configured to, in the sensing mode, lower a high potential driving voltage supplied to the display panel, sense a driving current of the display panel while the reference data voltage and the lowered driving voltage are applied and convert the sensed driving current into sensing data. Additionally, the display device includes a controller configured to calculate a compensation factor based on the sensing data. Further, in a display mode, the compensation factor is used to compensate image data. In addition, provided is a method for compensating for degradation of a display device.
