Photonics and flexible display applications of phase-separated liquid crystals

Abstract

Anisotropic phase-separation of liquid crystal and polymer composite is highly applicable for obtaining the durable electro-optic devices. In this presentation, the theoretical model for phase separation phenomena based on the one-dimensional kinetic approach is introduced. For the applications of phase-separated LCs, we propose the fabrication of mechanically stable flexible display and electrically controllable microlens array using two- or three-dimensional anisotropic phase separation. Since LC molecules are isolated by polymer structure due to the anisotropic phase separations, resultant devices show very good mechanical stability against external pressure and stable electro-optic characteristics.
