Abstract:
1. A data-driving apparatus for a liquid crystal display device, comprising: 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 outputting the time-divided pixel data with an unshifted output channel and the time-divided pixel data shifted to the right side by one channel in response to a polarity control signal having a polarity inverted 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 outputting the analog pixel signals with an unshifted output channel and outputting the analog pixel signals shifted to the left side by one channel in response to the polarity control signal 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.
