Abstract
A display device may include a pixel unit which includes pixels, a driver which drives the pixel unit based on image data, a voltage generator which provides a driving voltage to the pixel unit, and a global current manager including a compensation voltage generator which receives a comparison result between a sensing current of the pixel unit and a reference current range generated based on the image data from a comparator and generates a compensation voltage for controlling the driving voltage, and a compensation data generator which generates compensation data for controlling grayscale values of the image data in a dithering method based on the comparison result.
