Abstract: An electronic device includes an organic light emitting diode (OLED) display device, and a display controller configured to provide image data to the OLED display device. The display controller calculates stress data for the OLED display device by accumulating the image data, and determines a compensation factor for the OLED display device based on the stress data. The OLED display device receives the image data and the compensation factor from the display controller, converts the image data into compensated image data based on the compensation factor, and displays an image based on the compensated image data.
