Abstract

Polymer-stabilized blue phase liquid crystals (PSBPLC) within wide temperature range attract many attentions

such as fast response time short as sub-millisecond

alignment-free and polarization independent. It has potential huge application for PSBPLC both in display technology and optical-electronic devices. The micro phase model and Kerr effect for PSBPLC were described.This paper introduced for PSBPLC development in microlens technology including main kinds of microlens structures such as BPLC microlens with hole pattern

adaptive BPLC microlens with curved electrode

BPLC GRIN microlens

BPLC microlens with resistive film and BPLC microlens with ZnO nano-rod electrode.
