<p>The present invention relates to a Liquid Crystal Driving Circuit and more particularly to a Source Driving of Liquid Crystal Display Device and a method for displaying high gray scale by simple Circuit. The present invention of a Source Driving Circuit for driving a Data Line of Liquid Crystal Display Device according to Video Data comprising Digital block, Digital-Analog Converter, Operational amplifier. The first Switch, and the second Switch. The present invention is available to display high gray scale with using the operational amplifier, which has equality of the extent of six bits by compensating for error by dividing one Line Time, which inputs Video Signal to Data Line into two Step, driving Data Line of Panel by the Output of operational amplifier at the first time and driving directly Data Line by the Output Digital-Analog Converter.</p> |
