Claim:
1. A display device comprising: a pixel unit comprising: a timing controller that receives first data from an outside, wherein the pixel unit displays an image corresponding to the first data; a converter that receives the first data from the timing controller, to extract luminance components of the first data corresponding to the pixels to determine luminance distribution of the first data, divides the luminance distribution into a plurality of luminance distribution ranges, and converts the first data into second data by regulating an input gray level of the first data based on a conversion equation corresponding to a variation between data of the luminance distribution ranges; and a data driver that receives the second data from the converter and to provide the second data to the data lines, wherein a gradient of the conversion equation for regulating the input gray level is continuously changed depending on the input gray level of the first data.
