Patent ID: 7030844

Claim:
A data-driving apparatus for a liquid crystal display device, comprising: 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 one frame, and supplying the time-divided pixel data; a second multiplexer array alternately changing output channels of the pixel data in response to a polarity control signal having a polarity inverted for each of 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 in response to the polarity control signal; 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.
