Abstract: A data driver according to an exemplary embodiment includes a plurality of first output channels, a plurality of second output channels, a data controller and a data driving integrated circuit IC. The plurality of first output channels are connected to a plurality of data lines. The data controller receives an image data signal and a data control signal. The data controller generates an image data of one frame unit according to the image data signal and the data control signal. The data controller generates an output channel on/off data based on channel selection data. The data driving IC generates a plurality of data signals and a plurality of dummy signals according to the image data of one frame unit. The data driving IC switches a plurality of first switches transmitting the plurality of data signals to the plurality of first output channels and a plurality of second switches transmitting the plurality of dummy signals to the plurality of second output channels. The image data signal includes the channel selection data, the plurality of first output channels and the plurality of second output channels.

Abstract: A display apparatus includes a timing controller, a data driver and a display panel. The timing controller generates a mode selection signal and output image data in response to input image data. The data driver generates first through N-th data voltages in response to the mode selection signal and the output image data and applies the first through N-th data voltages to first through N-th data lines. The display panel is connected to the first through N-th data lines. During the first operation mode, each of a polarity pattern of first through M-th data voltages and a polarity pattern of (M+1)-th through N-th data voltages repeats a first polarity pattern. During the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern.
