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.
