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.

Driving controller, display device, and method of driving display device

A display apparatus includes a display panel, a compensator, a controller, and a data driver. The compensator determines a degradation grayscale of a compensation region of the display panel. The degradation grayscale may be determined based on a driving time of at least one pixel in the compensation region and degradation data corresponding to the at least one pixel. The controller generates compensated image data for input image data based on the degradation grayscale. The data driver provides a data voltage to the at least one pixel based on the compensated image data.

Display apparatus and method of driving display apparatus
