Claim 16:
17. A method of driving a display device comprising a display panel including a plurality of pixels and partitioned into a plurality of blocks including at least one of the pixels, a timing controller configured to receive input image data from an outside source and generate scaled image data by scaling the input image data using a scale factor, and a data driver configured to generate a data signal corresponding to the scaled image data and supply the data signal to the pixels, the method comprising:
measuring a current flowing through the pixels to generate a global current value;
generating a unit target current value based on the global current value corresponding to a reference block among the blocks;
generating a load value for each of the blocks, based on the input image data;
generating temperature data for each of the blocks, based on the load value for each block;
calculating a frame load value based on the load value for each block, first weight data, and second weight data;
generating a target current value based on the frame load value and the unit target current value; and
calculating the scale factor by comparing the target current value and the global current value.
