ABSTRACT:
Circuits and methods are provided for driving flat panel displays (e.g., a liquid crystal display (LCD)), which provide reduced power consumption for driving data lines of flat panels displays. Source driving circuits and methods for driving data lines use both intermediate reference voltages and boosted driving voltages in each driving cycle (as opposed to entirely using boosted driving voltages) to reduce power consumption and provide charge recycling.
