Ionic Effects in Bistable Reflective Cholesteric Liquid Crystals

We have found that ionic effects play an important role in driving cholesteric liquid crystal displays. The ions change the effective electric field inside the liquid crystal and help to create nucleation seeds for transitions. These effects reduce the driving voltages by about 10, make the response of the liquid crystal faster, and result in a higher contrast ratio.
