Abstract: A method of driving a display panel includes compensating first pixel data corresponding to a first pixel of a plurality of pixels in the display panel based on at least one of a first decision, a second decision, or a third decision and generating a first data voltage corresponding to the compensated first pixel data. The first data voltage is applied to the first pixel through a data line. The first decision includes determining, based on a position of the first pixel, whether compensation for the first pixel data is required. The second decision includes determining, based on previous subpixel data and present subpixel data for the first pixel, whether the compensation for the first pixel data is required. The third decision includes determining whether the first pixel data complies with a compensation avoidance condition.

Abstract: A data driver includes a receiver, a transition minimization coding (“TMC”) decoder, a dithering adder and a voltage generator. The receiver receives a clock signal and first image data which is generating by removing a dithering from a dithered original image data and performing a TMC. The TMC decoder removes the TMC from the first image data to generate second image data. The dithering adder restores the removed dithering based on the clock signal and the second image data to generate third image data. The voltage generator generates a plurality of data voltages based on the third image data.
