Abstract: According to an embodiment of the present disclosure, a method for controlling a display device includes inputting frame data for each frame input period of a vertical synchronization signal, accumulating stress data for some pixels in predetermined accumulation units based on the frame data for each blank period of the vertical synchronization signal, accumulating an input time of the frame data, calculating a correction gain value for correcting the accumulated stress data based on the input time accumulated when the accumulation of the stress data is completed for all pixels, correcting the accumulated stress data based on the correction gain value, and storing the corrected accumulated stress data.

Abstract: Embodiments of the disclosure relate to a controller and a display device. As the display device is driven, the stress value is accumulated, and a compensation value based on the accumulated stress value is applied upon driving the display. Thus, it is possible to compensate for degradation of subpixels in real time. Further, the amount of degradation of the subpixel is sensed at a preset time, and the stress value is corrected based on the degradation amount sensing data. Thus, it is possible to enhance the accuracy of real-time compensation for degradation of subpixels while minimizing sensing of degradation of subpixels.
