    Abstract: A display apparatus includes a display panel including a first pixel, a common voltage generator and a timing controller. The common voltage generator generates a reference common voltage, and provides the reference common voltage to the first pixel. The timing controller determines a dithering scheme for the first pixel based on first common voltage information, and generates first output pixel data by applying a dithering function to first input pixel data based on the dithering scheme for the first pixel. The first common voltage information indicates whether the reference common voltage is substantially equal to an optimal common voltage of the first pixel. A first data voltage provided to the first pixel is generated based on the first output pixel data. A polarity of the first data voltage is reversed with respect to the reference common voltage for each predetermined duration. A phase of the first data voltage is symmetric or asymmetric with respect to the reference common voltage depending on the dithering scheme for the first pixel.

    Abstract: A timing controller for a display apparatus includes a polarity comparison part and a compensation part. The polarity comparison part compares a first polarity of a first data voltage with a second polarity of a second data voltage, the first data voltage corresponding to a first pixel in a first frame and generated based on a first gamma voltage, the second data voltage corresponding to the first pixel in a second frame and generated based on a second gamma voltage. The compensation part compensates the second data voltage based on a first look-up table, if the first polarity is the same as the second polarity, and compensates the second data voltage based on a second look-up table, if the first polarity is different from the second polarity.
