Classification: CPC G  H | IPC G  H

Claim 1:
2. The display device according to claim 1, wherein the first logic circuit comprises:
a current sensor configured to measure the current flowing through the pixels to generate the global current value;
a first calculator configured to generate a unit target current value based on the global current value corresponding to a reference block among the blocks;
a second calculator configured to generate the load value for each of the blocks, based on the input image data;
a third calculator configured to generate temperature data for each block of the blocks, based on the load value for each block;
a fourth calculator configured to calculate a frame load value based on the load value for each block, the first weight data, and the second weight data, and to generate the target current value based on the frame load value and the unit target current value; and
a second logic circuit configured to calculate the scale factor by comparing the target current value and the global current value.
