Electro-optics of polymer-stabilized blue phase liquid crystal displays

TLDR

Electro‑optics of polymer‑stabilized blue phase liquid crystal displays (BP LCDs) are analyzed and experimentally validated. The study develops a numerical model to characterize and optimize the electro‑optical and display properties of BP LCDs in in‑plane and fringe‑field switching cells. The model simulates a wide‑view BP LCD with a single biaxial compensation film, evaluating in‑plane and fringe‑field switching configurations. Simulations show voltage‑dependent transmittance curves that match measurements, and indicate that reducing electrode width and gap while increasing Kerr constant lowers operating voltage without sacrificing transmittance.

Abstract

Electro-optics of polymer-stabilized blue phase liquid crystal displays (BP LCDs) is analyzed and validated experimentally. A numerical model for characterizing and optimizing the electro-optical and display properties of BP LCDs in in-plane switching and fringe field switching cells is developed. The simulated voltage-dependent transmittance curves agree well with the measured results. To lower the operating voltage while keeping a high transmittance, both electrode width and gap, and large Kerr constant make important contributions. A wide-view BP LCD using a single biaxial compensation film is simulated.
