Abstract
A method is disclosed of electrically controlling state transition of a liquid crystal material in a device (). The device () comprises the liquid crystal material () and a polymeric structure () consisting of polymerised liquid crystal material with a selected liquid crystal state. The method comprises: applying an electric field to the liquid crystal material () to force the liquid crystal material () into a high-energy state; reducing the strength of the electric field to cause a lower-energy state region of the liquid crystal material () to nucleate on at least a part of the polymeric structure ().
