  • Publication number: 20160189651
    Abstract: Among data voltages applied to a plurality of pixels on a display panel, a first data voltage is shifted from a first original data voltage by a first value, a second data voltage is shifted from a second original data voltage by a second value, and a third data voltage is shifted from a third original data voltage by a third value to compensate for AC and DC afterimages. A common voltage generator provides an optimal common voltage for the third data voltage when the temperature of the liquid crystal panel assembly is lower than a reference temperature and provides an optimal common voltage for the first data voltage or the second data voltage when the temperature of the liquid crystal panel assembly is higher than or equal to the reference temperature. The first, second, and third values correspond to respective kickback voltages of the respective gray level data voltages.

  • 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.
