1. A display device comprising:
a frequency calculator configured to calculate a driving frequency of a previous frame, and compare the driving frequency of the previous frame and a threshold driving frequency;
a compensation data calculator configured to calculate compensation data based on a comparison result of the frequency calculator that the driving frequency of the previous frame is lower than the threshold driving frequency;
a data storage configured to provide the compensation data corresponding to the calculated compensation data to an image data output unit; and
the image data output unit configured to output the compensation data to a data driver.
