1. A display device, comprising:
a display panel including a plurality of pixels;
a current sensor that senses a sensing current that flows through the pixels; and
a first circuit that calculates a target current by multiplying grayscale values of an image frame of input image data by position weights related to a current deviation for each position of the image frame, and that generates a scale factor by comparing the target current and the sensing current.
