Display device and method for compensating degradation of display device

A display device, comprising:

• a display panel including a plurality of pixels;
• a plurality of readout integrated circuits to perform a readout operation of detected values including degradation information of the pixels, via a plurality of readout lines connected to the pixels, when a degradation detecting operation is performed;
• a deviation corrector to calculate weighted values to correct operating deviation of the readout integrated circuits based on an average of initial values, and to generate corrected image data to correct input image data based on the weighted values, the initial values being the detected values output from the readout integrated circuits when the display panel is in an initial state in which the pixels are non-degraded;
• a scan driver to provide a scan signal to the display panel via a plurality of scan lines;
• a data driver to provide data signals corresponding to the corrected image data to the display panel via a plurality of data lines;
• and
• a timing controller to control the readout integrated circuits, the scan driver, and the data driver.
