Abstract
A data-driving a liquid crystal display includes a first multiplexer array for alternately changing a supplying sequence of time-divided pixel data and time-divided pixel data, a second multiplexer array for alternately outputting the time-divided pixel data with an unshifted output channel of the time-divided pixel data and outputting the time-divided pixel data shifted to the right side by one channel in response to a control signal, 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 for 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 in response to the control signal, and a demultiplexer array for alternately changing a supplying sequence of the time-divided pixel signals for each horizontal period and each frame.
