  • Patent number: 11972721
    Abstract: A display device is disclosed that includes pixels, a memory, and a degradation compensator. The pixels include light emitting elements. The memory is operable to store degradation information including degradation degrees of the light emitting elements. The degradation compensator is operable to receive the degradation information and generate output grayscales by changing each of input grayscales of the pixels in proportion to each of the degradation degrees. The degradation compensator includes a degradation information changer for changing the degradation information by decreasing a degradation degree having a variation greater than a threshold value among variations of the degradation degrees.
