    Abstract: A method of driving a display panel includes determining a first black gap corresponding to a 2D mode and a second black gap corresponding to a 3D mode. The first and second black gaps are different from each other, the first and second black gaps correspond to a voltage difference between a black voltage of a first polarity and a black voltage of a second polarity, and the first and second polarities are opposite to each other with respect to a reference voltage. The method further includes dividing a voltage difference between a white voltage of the first polarity and the black voltage of the first polarity to generate a plurality of gamma voltages of the first polarity, and dividing a voltage difference between a white voltage of the second polarity and the black voltage of the second polarity to generate a plurality of gamma voltages of the second polarity.

    Abstract: A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.
