Claim 3:
4. The display device of claim 1, wherein the current control circuit includes:
a gray-luminance converter configured to convert gray levels represented by pixel data included in the first through N-th line data for the first through the N-th pixel rows into pixel luminances for each of the first through the N-th pixel rows;
a line luminance calculator configured to calculate a line luminance for each of the first through the N-th pixel rows by summing the pixel luminances for each of the first through the N-th pixel rows;
an average luminance level determiner configured to store line luminances for the first through the N-th pixel rows in a first-in first-out (FIFO) manner, and to determine an average panel luminance level based on the line luminances for the first through the N-th pixel rows;
a luminance domain scale factor determiner configured to determine a luminance domain scale factor corresponding to the average panel luminance level; and
a gray domain scale factor determiner configured to convert the luminance domain scale factor into a gray domain scale factor as the current control value.
