ABSTRACT:
A source driving circuit includes a source driver circuit, an intermediate voltage generator, and a switching control unit. The source driver circuit receives display data and generates a source driving voltage corresponding to the received display data The intermediate voltage generator generates an intermediate source driving voltage. The switching control unit receives a plurality of control signals for selectively applying the source driving voltage and the intermediate source driving voltage to data lines of a display as a driving voltage and controls an order of transition to final levels of a common electrode voltage and the driving voltage. The common electrode voltage may be applied to a common electrode of a liquid crystal capacitor coupled to the data line of the display.
