An exemplary LCD ( 30 ) includes a liquid crystal panel ( 31 ) configured for displaying images and a driving circuit ( 30 ). The driving circuit includes a pulse generator configured for providing a pulse signal, and a charge pump ( 315 ) configured for provide a common voltage to the liquid crystal panel according to the pulse signal. The common voltage is adjusted by adjusting a duty ratio of the signal pulse, and the precision of adjustment of the common voltage is determined according to a resolution of the pulse signal.
