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

In a method of driving a display panel, user image data which photographs a user is received and user location data which a location of the user is mapped on a display panel is outputted. A plurality of configuration region data configured in a row on the display panel and user location data are compared, and a motion control signal which controls a motion of the display panel according to the coincidence between the user location data and the configuration region data. A motion of the display panel is controlled in response to the motion control signal. Therefore, the display quality of a display device which displays a three-dimensional stereoscopic image is able to be improved.
