    Abstract: A data driving circuit, controller, and display device include a compensation table for compensating for degradation of a light emitting subpixel. The compensation table may be generated or updated based on degradation of a dummy subpixel. The dummy subpixel is disposed in a non-active area, and has the same or similar characteristics to those of the light emitting subpixel as the display device is driven. Degree of degradation of the dummy subpixel may be sensed, and by degrading the dummy subpixel more rapidly than the light emitting subpixel, accuracy of sensing may be enhanced. The degradation compensation is performed in real time during driving of the display device, and is based on the compensation table generated or updated using the degree of degradation sensed on the dummy subpixel.
