ABSTRACT:
This invention provides a method and an apparatus for power reduction for LCD drivers using backplane charge sharing. In addition, this invention relates to the use of switches between adjacent backplane drivers in order to transmit and reuse the discharged charge from one backplane's capacitance in order to charge the capacitance of an adjacent backplane. One embodiment of this invention utilizes N metal oxide semiconductor field effect transistors, NMOS-FETs to implement the switch connection between adjacent backplane drivers.
