    Abstract: Provided are display devices and methods of driving the same. A display device may include: a display panel, a main sound generator and a sub-sound generator disposed on a surface of the display panel. The main sound generator outputs sound in a first directional mode, and each of the main sound generator and the sub-sound generator outputs sound in a second directional mode. Each directional mode may be a mode in which sound is directed towards a particular viewer's location.
