A data compensator includes first logic, second logic, third logic, fourth logic, and fifth logic. The first logic calculates block compensation coefficients for blocks in a first frame based on first pixel data of the first frame. The second logic generates first gamma applied pixel data based on the first pixel data of the first frame and to generate second gamma applied pixel data based on the first gamma applied pixel data and second pixel data of a second frame adjacent the first frame. The third logic selects a number of the block compensation coefficients based on a pixel coordinate. The fourth logic generates a pixel compensation coefficient corresponding to the second pixel data by interpolating the selected block compensation coefficients based on the pixel coordinate. The fifth logic generates output pixel data based on the second gamma applied pixel data and the pixel compensation coefficient.
