Abstract
An apparatus and method for data-driving a liquid crystal display device is disclosed in the present invention. The apparatus includes a first multiplexer array performing a time-division on inputted pixel data into odd-numbered and even-numbered pixel data, alternately changing a supplying sequence of the time-divided pixel data for each horizontal period and each frame, and supplying the time-divided pixel data, a second multiplexer array alternately maintaining an output channel of the time-divided pixel data and outputting the time-divided pixel data shifted to the right side by one channel for each horizontal period, a digital-to-analog converter array converting the time-divided pixel data into analog pixel signals having a polarity opposite to the pixel data of adjacent channels, a third multiplexer array alternately maintaining the output channel of the pixel signals and outputting the pixel signals shifted to the left side by one channel for each horizontal period, and a demultiplexer array performing a time-division on data lines into odd-numbered and even-numbered data lines and supplying the pixel signals to the time-divided data lines, and alternately changing a supplying sequence of the pixel signals for at least one horizontal period and one frame.
