Claim 8:
9. The display device of claim 1, wherein the controller comprises:
an average data calculation block configured to generate average data by calculating an average of the input image data for each of the plurality of pixels;
a first stress map generation block configured to generate the first stress map representing first block stress values of the plurality of first pixel blocks based on the average data;
a second stress map generation block configured to generate the second stress map representing second block stress values of the plurality of second pixel blocks based on the average data;
a first stress map interpolation block configured to calculate a first stress value for each of the plurality of pixels by performing a bilinear interpolation operation on the first block stress values of the first stress map;
a second stress map interpolation block configured to calculate a second stress value for each of the plurality of pixels by performing a bilinear interpolation operation on the second block stress values of the second stress map;
a stress map unity block configured to calculate the united stress value for each of the plurality of pixels by applying a first weight to the first stress value and applying a second weight to the second stress value; and
a stress compensation block configured to generate the output image data for each of the plurality of pixels by compensating the input image data for each of the plurality of pixels based on the united stress value for each of the plurality of pixels.
