Claim 10:
11. A display device comprising:
a pixel including a light emitting unit including sub element groups electrically connected in series, each sub element group including light emitting elements electrically connected in parallel;
a deterioration value extractor that extracts deterioration values of the sub element groups according to a number of the light emitting elements of the each sub element group using a look up table that stores a deterioration value for each number of the light emitting elements, wherein the number of the light emitting elements of the each sub element group is obtained by at least one of optical imaging, thermal imaging, and pixel sensing;
a luminance value calculator that calculates luminance values of the sub element groups by applying the deterioration values;
a correction luminance calculator that calculates a current luminance value of the pixel by summing the luminance values, and calculates a correction luminance value by comparing the current luminance value with a reference luminance value; and
a corrector that generates compensation data by applying the correction luminance value to image data.
