    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 display apparatus includes a display panel, a contrast analyzer, a contrast processor and a data driver. The display panel includes a plurality of sub display areas. The display panel is configured to display an image based on input image data. The contrast analyzer is configured to analyze the input image data in a time division method. The contrast processor is configured to adjust contrast of the input image data based on analysis result of the contrast analyzer. The data driver is configured to generate data voltages based on output data of the contrast processor. A number of contrast analysis cores of the contrast analyzer is determined according to a number of the sub display areas and a frame rate.
