A polarity sensitive bistable color effect has been observed in cholesteric liquid crystal—polymer mixtures where a gradient of the polymer network density is created by strongly absorbed UV light. The switching between two stable states is driven by electric pulses of the same amplitude and duration but with opposite electric polarity. The effect could be of great interest for practical applications in color display technology.
