Abstract
An encapsulated polymer stabilized cholesteric texture (EPSCT) light shutter is formed from a cholesteric liquid crystal and monomer that is encapsulated into micron sized, polymer-coated droplets by either an emulsification or phase separation process. The polymer-coated droplets are disposed between transparent electrodes, where they are irradiated by ultra-violet (UV) light to polymerize the monomer.
