摘要： A liquid crystal display device is set forth that comprises a data line that is connected to drive a liquid crystal cell and an output driver connected to selectively provide a pixel drive signal to the data line. The pixel drive signal corresponds to a digital video data signal provided to the liquid crystal display device. A pre-charging circuit is used to reduce the power consumed by the output driver. To this end, the pre-charging circuit is connected to selectively pre-charge the data line to one or more of a plurality of voltage levels depending on the value of the digital video data signal. In one embodiment, the plurality of voltage levels comprises a positive pre-charge voltage, a negative pre-charge voltage, and a charge share voltage. The magnitudes of the positive pre-charge voltage and the negative pre-charge voltage may be chosen so that they are greater than the magnitude of the charge share voltage.
