Claim 2:
3. The display device of claim 1, wherein the data compensator includes:
a captured gamma calculator configured to calculate captured gamma data based on the captured luminance data;
a captured luminance ratio calculator configured to calculate captured luminance ratio data corresponding to a ratio of the captured luminance data to a captured target luminance based on the captured luminance data;
a measured gamma calculator configured to calculate measured gamma data based on the measured luminance data;
a measured luminance ratio calculator configured to calculate measured luminance ratio data corresponding to a ratio of the measured luminance data to a measured target luminance based on the measured luminance data; and
a compensation grayscale calculator configured to calculate the compensation grayscale data for the measured grayscale based on the input grayscale data for the measured grayscale, the captured gamma data, the captured luminance ratio data, the measured gamma data, and the measured luminance ratio data.
