Patent ID: 6963328

Claim:
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 at least one horizontal period and one 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 with a shifted output channel to the right side by one channel for each of at least two horizontal periods in response to a polarity control signal having a polarity inverted for each of the at least two horizontal periods; 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 pixel signals with an unshifted output channel of the pixel signals and outputting the pixel signals shifted to the left side by one channel for the at least two horizontal periods in response to the polarity control signal; 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 time-divided pixel signals for each horizontal period and each frame.
