The electric-field-induced birefringence of a polymer-dispersed blue phase liquid crystal (PS-BPLC) cell is usually described by the Kerr effect or extended Kerr effect. However, because of the lattice distortion of the PSBPLC, the induced phase change is difficult to obtain by simulation.In this study, we propose a double-high- pretilted-twist-nematic (DHPTN) director model to simulate a blue phase liquid crystal cell.
