Abstract
Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.
