    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 luminance adjustment part includes a luminance determination part and a data compensation part. The luminance determination part may determine a control value for controlling luminance of a backlight assembly using linear image data that has a linear luminance profile and is generated by performing a de-gamma process on a first copy of input image data that has a nonlinear luminance profile. The compensation part may compensate pixel data that corresponds to pixels of a display panel using the control value, the pixel data being generated using a second copy of the input image data. Thus, color distortion of a displayed image as perceived by a viewer may be minimized when power consumption of a display apparatus that includes the display panel is decreased.
