Bragg Reflective Polymer Stabilized Cholesteric Liquid Crystal Display

Asymmetric tunable Fabry-Perot cavity using switchable polymer stabilized cholesteric liquid crystal optical Bragg mirror

Optical properties of an asymmetric Fabry-Perot (FP) cavity interferometer made up of a conventional metallic mirror and a polymer stabilized cholesteric liquid crystal (PSCLC) Bragg mirror have been investigated. The first FP cavity design comprises a gold mirror, an iso-tropic layer made up of the polymer glue, a quarter wave plate to convert the input linearly polarized modes into the circul...

Review on polymer-stabilized short-pitch cholesteric liquid crystal displays

Submillisecond response times and low operation voltage are critical to next generation liquid crystal display and photonic devices. In this paper, we review the recent progress of three fastresponse short-pitch cholesteric liquid crystal modes: blue phase (BP), uniform standing helix (USH), and uniform lying helix (ULH). This review starts with a brief introduction of device structures and wor...

A Polymer-Stabilized Single-Layer Color Cholesteric Liquid Crystal Display with Anisotropic Reflection

UV-cured cholesteric polymer-dispersed liquid crystal display

We describe the preparation and electro-optic characteristics of a color display which makes use of the selective reflection of cholesteric droplets embedded in a polymer film. The polymer film is formed by a UV-curable adhesive, as opposed to the thermoplastic polymers which have been used previously. The new systems are easy to prepare and suitable for operation at room temperature. They show...

Emerging Polymer-Stabilized Blue Phase Liquid Crystal Display

Polymer-stabilized blue-phase liquid crystals hold great potential for future display applications. Some technical challenges, such as blue-phase temperature range, operation voltage, hysteresis, and voltage holding ratio remain to be overcome before widespread commercialization can be realized. In this paper, we review recent advances in this emerging technology.
