1. A degradation compensator, comprising:
a compensation factor determiner configured to determine a compensation factor based on an aperture ratio between adjacent sub-pixels; and
a data compensator configured to apply the compensation factor to a stress compensation weight to generate compensation data for compensating image data,
wherein the compensation factor decreases as a distance between the adjacent sub-pixels increases, and
wherein the compensation factor determiner is configured to determine the compensation factor using a lookup table comprising a relationship of the distance between the adjacent sub-pixels and the compensation factor.
