Claim 0:
1. 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;
a data driver configured to generate a data signal corresponding to the scaled image data and supply the data signal to the pixels; and
a first logic circuit configured to measure a current flowing through the pixels to generate a global current value, to generate a load value for each of the blocks based on the input image data, to generate a target current value based on the load value for each of the blocks, first weight data including a first weight for a current characteristic of the pixels corresponding to a temperature of the display panel, and second weight data including a second weight for an efficiency characteristic of the pixels corresponding to the temperature, and to determine the scale factor based on the global current value and the target current value.
