Claim 0:
1. A display device comprising:
pixels including light emitting elements;
a memory configured to store degradation information including degradation degrees of the light emitting elements; and
a degradation compensator configured 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,
wherein the degradation compensator includes a degradation information changer configured to change the degradation information by decreasing a degradation degree having a variation greater than a threshold value among variations of the degradation degrees,
wherein the degradation compensator further includes a grayscale changer configured to generate the output grayscales corresponding to the input grayscales and the changed degradation information with reference to a first lookup table, and
wherein the first lookup table includes output gray scales corresponding to first degradation degrees greater than or equal to an initial degradation degree set initially with respect to the pixels and output grayscales corresponding to second degradation degrees smaller than the initial degradation degree.
