Method of driving a display panel and a display apparatus for performing the same

A display apparatus comprising:

• a pixel polarity determining part configured to determine a present polarity of a pixel data signal of a present frame;
• a grayscale compensating part configured to generate a first compensated grayscale of the pixel data signal of the present frame by using a pixel data signal of a previous frame, the pixel data signal of the present frame, and the present polarity, wherein the first compensated grayscale varies according to the present polarity;
• and
• a display panel configured to display an image using the first compensated grayscale.

A method of driving a display panel, the method comprising:

• determining a present polarity of a pixel data signal of a present frame;
• merging the present polarity with the pixel data signal of the present frame to generate a first merged signal of the present frame;
• delaying the first merged signal to generate a second merged signal of a previous frame;
• extracting the present polarity from the first merged signal;
• extracting a previous polarity of a pixel data signal of the previous frame from the second merged signal;
• and
• generating a compensated grayscale using the pixel data signal of the previous frame, the pixel data signal of the present frame, the previous polarity, and the present polarity,
• wherein the compensated grayscale varies according to the previous polarity and the present polarity.
