Abstract: A method of driving a display panel includes determining a present polarity of a pixel data signal of a present frame, generating a first compensated grayscale of the pixel data signal of the present frame using a pixel data signal of a previous frame, the pixel data signal of the present frame, and the present polarity, and displaying an image using the first compensated grayscale. The first compensated grayscale varies according to the present polarity.
