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