Abstract:
1. A driving apparatus for a liquid crystal display, comprising: a first multiplexor array to perform time-division on input pixel data to supply time-divided pixel data having a horizontal period divided into four ¼ periods; a digital-analog conversion array to convert the time-divided pixel data pixel into voltage signals; and a demultiplexor array to drive data lines by performing time-division on the pixel voltage signal by the ¼ periods wherein the first multiplexor array includes at least N (N being a positive integer) of multiplexors and performs time-division on a plurality of input pixel data to supply the time-divided pixel data, wherein the digital-analog conversion array converts the time-divided pixel data into the pixel voltage signals, and wherein the demultiplexor array includes at least N of demultiplexors and supplies the pixel voltage signals into a plurality of data lines; wherein the digital-analog conversion array includes at least N+1 positive and negative digital-analog converters to convert the time-divided pixel data into the pixel voltage signals, the positive and negative digital-analog converters being alternately arranged.
