Common Voltage driver circuits and methods providing reduced power consumption for driving flat panel displays

摘要

Circuits and methods are provided for driving flat panel displays (e.g., a liquid crystal display (LCD)) and, in particular, to common voltage driver circuits and methods that provide reduced power consumption for driving common electrodes of flat panels displays. Circuits and methods for driving a common electrode 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.
