Method of driving a display panel, display panel driving apparatus for performing the method and display apparatus having the display panel driving apparatus

摘要

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.

主权项

1. A method of driving a display panel by a display panel driving apparatus comprising a viewer position determining part and a data driving part, the method comprising:
detecting by the viewer position determining part a position of a viewer to output a viewer position detection signal; determining by the viewer position determining part whether the viewer is less than a reference distance from the display panel or not less than the reference distance from the display panel based on the viewer position detection signal; and driving by the data driving part a unit pixel of the display panel using a single gamma value when the viewer is determined by the viewer position determining part to be less than the reference distance from the display panel and using a plurality of gamma values when the viewer is determined by the viewer position determining part to be not less than the reference distance from the display panel.
