Abstract: A method of driving a display panel determines whether an image mode of an image signal is a 2D flat image mode or a 3D stereoscopic image mode. A first reverse signal and a second reverse signal different from the first reverse signal are generated according to the image mode. The image signal is converted to a first polarity data voltage or a second polarity data voltage with respect to a reference voltage based on the first reverse signal or the second reverse signal, and the first polarity data voltage or the second polarity data voltage is outputted to a display panel. During the 3D stereoscopic image mode, polarities of data voltages are reversed at a period of a plurality of frames, so that display quality of the 3D stereoscopic image may be enhanced.

Abstract: An active headrest apparatus for a vehicle seat. A contact area in which the upper body of a person who is seated in a car in the event of a rear-end collision of the car is moved backward due to an inertial force and contacts a back plate can be increased, and a distance at which a headrest is moved and rises can be increased so that the function of an active headrest can be more faithfully performed and neck injury of the person who is seated in the car can be prevented to the maximum.
