1. A display device, comprising: a display unit which includes a plurality of pixels disposed in the display unit; a degradation controller which includes a voltage compensator configured to calculate a driving voltage increase amount based on a degradation amount of a maximum degradation pixel among the pixels and a global current controller configured to calculate a first scale factor for compensating a power increase amount according to the driving voltage increase amount; a driving voltage provider which is configured to increase a driving voltage provided to the pixels based on the driving voltage increase amount; a data compensator which is configured to generate output image data by scaling the first scale factor to grayscale values of input image data; and a data driver which is configured to provide data voltages to the pixels based on the output image data, wherein the data driver receives the output image data modified from the input image data based on the first scale factor, and wherein the output image data modified from the input image data based on the first scale factor is received from the data compensator which is disposed outside the display unit and is not a part of the data driver.
