Abstract: A method of driving a display panel includes detecting a position of a viewer to output a viewer position detection signal, determining whether the position of the viewer is in a first area or in a second area based on the viewer position detection signal to output a viewer position signal, and driving a unit pixel of the display panel using a plurality of gamma values according to the viewer position signal. The first area is less than a reference distance, and the second area is not less than the reference distance. Thus, side visibility of a display apparatus may be improved.

Abstract: A display panel driving apparatus includes a first switching element and a second switching element. The first switching element applies first pixel data to a first pixel connected with a first data line of a display panel during a first sub frame period. The first switching element is connected with a data channel of a data driving part. The second switching element applies second pixel data having a level higher than a level of the first pixel data to a second pixel connected with a second data line of the display panel during a second sub frame period. The second switching element is connected with the data channel. Thus, display quality of a display apparatus may be enhanced.
