Abstract: A degradation compensation apparatus including: a calculator provided with gray data regarding a plurality of consecutive frames, the calculator calculating and outputting a frame degradation amount of a current frame, which indicates a degree of degradation of the current frame; a memory accumulating and storing the frame degradation amount of the current frame and outputting a cumulative degradation amount, which is an accumulated degree of degradation of frames up to the current frame; and a data corrector correcting the gray data for a subsequent frame based on the cumulative degradation amount. Each of the plurality of consecutive frames includes first and second blocks each having a plurality of pixels, and the frame degradation amount is calculated based on one of the pixels included in the first block and one of the pixels included in the second block.
