  • Patent number: 10013945
    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.
