Electro-Optic Kerr Effect in Polymer-Stabilized Isotropic Liquid Crystals

Extended Kerr effect of polymer-stabilized blue-phase liquid crystals

Electric-field-induced birefringence of a polymer-stabilized blue-phase liquid crystal BPLC is investigated. In the low field region, conventional Kerr effect holds. As the electric field increases, the induced birefringence gradually saturates and deviates from Kerr effect. An exponential convergence model, called extended Kerr effect, is proposed to fit the experimental data. Good agreement b...

Emerging Liquid Crystal Displays Based on the Kerr Effect

The device physics and electro-optical properties of emerging liquid crystal displays (LCDs) based on the Kerr effect are investigated. With a voltage applied, both blue phase and polymer-stabilized blue phase exhibit a fascinating isotropic-toanisotropic transition. We have developed a numerical model to understand the underlying device physics in order to optimize device performance. The oper...

Optically-isotropic nanoencapsulated liquid crystal displays based on Kerr effect.

An innovative liquid crystal display (LCD), incorporating in-plane switching mechanism with LC nanoencapsulation, is developed and its electro-optic (EO) performances are characterized. The nanoencapsulated LCDs exhibit electric-field induced transitions from an optically-isotropic state to an anisotropic one based on Kerr effect. Extremely small size of LC droplets embedded in the nanoencapsul...

Extended Kerr effect in a polymer-stabilized blue-phase liquid crystal composite

Abstract As the electric field increases, the induced birefringence of a polymer-stabilized blue-phase liquid crystal gradually deviates from the conventional Kerr effect and finally saturates. A new convergence model, named extended Kerr effect, is proposed to explain this saturation phenomenon. This model will give a more accurate account on the electro-optic effect of the emerging bluephase ...
