  • Patent number: 9330617
    Abstract: There is provided a method of driving a display panel. In the method, it is determined whether a driving mode is a two-dimensional image mode or a three-dimensional image mode. A first gate driving control signal and a second gate driving control signal are generated by converting an input control signal inputted in accordance with the driving mode. A first gate signal is outputted to an odd-numbered gate line connected to a first sub-pixel within a unit pixel of the display panel based on the first gate driving control signal. A second gate signal is outputted to an even-numbered gate line connected to a second sub-pixel within the unit pixel of the display panel based on the second gate driving control signal.
