Abstract
A deterioration compensation apparatus includes a zone determiner, a stress generator, a first memory and a stress compensator. The zone determiner divides a display area into zones based on a distance from a central portion of the display area. The stress generator generates stress values of output image data for blocks including a plurality of pixels in the display area. The first memory accumulates the stress values of the output image data for the blocks and stores the accumulated stress values of the output image data for the blocks. The stress compensator receives the accumulated stress values of the output image data for the blocks and compensates input image data in a unit of pixels. A number of the pixels included in a block of the blocks varies according to the zone in which the pixels included in the block are located.
