Abstract
Disclosed are a data driver, a display device, and a method of driving the display device for improving the ability to express low-gray scale images. The method includes a shift process of shifting gray scale of input data by K gray scale and a data shift compensation process of reducing or preventing a luminance change using a shift gamma look-up table (LUT) so that a desired level of luminance can be generated.
