ABSTRACT:
A polymer stabilized cholesteric textures wafer is sandwiched between two electrode plates, one of which is transparent. Terminals are provided for connection in parallel with a circuit protection device of an AC circuit. If the circuit protection device opens circuits, AC is supplied to the electrodes across the polymer wafer. This drives the wafer to a reflecting state wherein it is coloured. This reflecting state may be viewed by an observer through the transparent electrode.
