Abstract

A display device includes a display unit which includes a plurality of pixels, 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 calculates 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.
