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.

Abstract: A display device includes: a display panel including pixels emitting light, based on a data voltage; a current limiter for determining a scale factor by comparing a previous frame load with a predetermined threshold load, and generating compensated image data by applying the scale factor to current image data as input image data of a current frame to adjust the data voltage; and a data driver for converting the compensated image data into the data voltage and providing the data voltage to the display panel.
