Abstract
A display device includes: a pixel component including pixels; a timing controller configured to calculate a load variation between previous input grayscale values corresponding to a previous frame and current input grayscale values corresponding to a current frame; a current sensor configured to sense a current flowing through the pixels during the current frame and generate a global current value for the sensed current, store time points at which the global current value becomes equal to preset threshold current values, respectively, and generate a global current variation rate corresponding to a section between the stored time points of the current frame; and a scale factor provider configured to control a scale factor in a period of the current frame in the case where the load variation is equal to or more than a reference load variation.
