Claim 14:
15. A method of driving a display device, the method comprising:
providing a pixel that includes a light emitting unit electrically connected between a driving transistor and a voltage source, the light emitting unit including a plurality of sub element groups electrically connected in series, wherein each sub element group includes a plurality of light emitting elements electrically connected in parallel;
obtaining a number of the light emitting elements of each of the sub element groups by at least one of optical imaging, thermal imaging, and pixel sensing;
extracting deterioration values of the sub element groups using a look up table that stores a deterioration value for each number of the light emitting elements;
calculating luminance values of the sub element groups by applying the deterioration values;
calculating a current luminance value of the pixel by summing the luminance values; and
calculating a correction luminance value by comparing the current luminance value with a reference luminance value.
