Abstract: A method of driving a display panel is provided. The method includes generating first compensated and second compensated data based on input image data, outputting the first compensated data to a data driver during a first frame, outputting the first smoothing data to the data driver during a second frame subsequent to the first frame, and outputting the second compensated data to the data driver during an n-th frame subsequent to the second frame (where n is a natural number greater than two). The first smoothing data has a value between a value of the first compensated data and a value of the second compensated data.

Abstract: Gamma applied data generating circuit includes motion vector extractor, gamma pattern generator, first gamma applier, second gamma applier, and output converter. Motion vector extractor extracts motion vector of object. Gamma pattern generator generates first gamma pattern corresponding to first motion vector value and second gamma pattern corresponding to second motion vector value from first time point. Value of motion vector is changed from first motion vector value to second motion vector value at first time point. First and second gamma appliers generate first and second data by applying first and second gamma pattern to input data, respectively. Output converter outputs sum of first data times first weight and second data times second weight as gamma applied data. From first time point to second time point, output converter converts first weight from 1 to 0 and converts second weight from 0 to 1.
