Title: Bistable liquid crystal displays and the method for driving the same

Abstract: A bistable chiral tilted-homeotropic nematic liquid crystal (BCTHN) display can be switched between the tilted-homeotropic state (TH state) and the twisted state (T state) by using dual frequency liquid crystal material. These two states can be maintained without the application of any electric field. The bistable liquid crystal display does not need high voltage to induce the flow of liquid crystal or break the anchoring energy.
