Abstract: A display apparatus includes a display panel comprising a plurality of data lines, a plurality of gate lines crossing the plurality of data lines and a plurality of pixels connected to the plurality of data lines and the plurality of gate lines, each of the plurality of pixels comprising a plurality of color sub-pixels, and a data driver configured to output data voltages of a positive polarity and a negative polarity opposite to the positive polarity with respect to the reference voltage to the plurality of data lines, wherein a polarity stuck period of at least one color sub-pixel of the plurality of color sub-pixels is different from a polarity stuck period of other color sub-pixel of the plurality of color sub-pixels, and the polarity stuck period is a pixel distance in which a same polarity moves per a frame.

Abstract: A method of driving a display panel includes outputting a gate signal to the display panel, varying a slew rate of a data voltage to be output to the display panel according to a position in the display panel at which the data voltage is to be applied, outputting the data voltage having the varied slew rate to the display panel, and displaying a grayscale on the display panel in response to the gate signal and the data voltage having the varied slew rate.
