Abstract
A method to drive bi-stable liquid crystal displays and related drivers and displays using same are disclosed. The method and driver use additional high impedance states of the outputs to save power while addressing bi-stable and multi-stable liquid crystal displays. The invention implements high impedance states at the driver outputs, allowing non-addressed sections of the display to electrically 'float' and by doing so reduces the required power to drive the display. Other advantages include improved visual effect of an update, such as reduced flash during the update, simpler operation, and better yields due to a larger operating window.
