Abstract
A display device of the disclosure includes a grayscale converter which converts input grayscales into output grayscales based on a scale factor, a data driver which converts the output grayscales into data voltages, a plurality of pixels which receives the data voltages and displays an image based on the data voltages, and a current sensor which provides a sensing current by sensing a first power current supplied to the plurality of pixels to display the image. When a load corresponding to the input grayscales is greater than a minimum load, the grayscale converter adjusts a change amount of the scale factor based on a current difference between a target current corresponding to the load and the sensing current.
