Polymer-Stabilized Diffraction Gratings from Cholesteric Liquid Crystals

Fast Flexoelectric Switching in Bimesogen-doped Polymer Stabilized Uniform Lying Helix and Vertical Standing Helix of Cholesteric Liquid Crystals

We report flexoelectric liquid crystal displays based on polymer-stabilized cholesteric liquid crystals with both uniform lying helix (PSULH) and vertical standing helix (PSVSH) modes. A method to enhance the flexoelectric switching of the CLC mixture is achieved by mixing nematic liquid crystal (NLC) constituents with the addition of a giant flexoelastic coefficient bimesogenic LC dimer into a...

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

Interlaced cholesteric liquid crystal fingerprint textures via sequential UV-induced polymer- stabilization

Two types of cholesteric liquid crystal (CLC) fingerprint structures, namely developable-modulation (DM) and growing-modulation (GM), can be contemporaneously prepared in polymer stabilized CLC (PSCLC) composites, to be mutually perpendicular in a repeatable and reversible voltage-switching process when the cell thickness to pitch length ratios (d/P) were appropriately chosen. PSCLC grating str...

Polymer-Stabilized Cholesteric Liquid Crystal for Polarization-Independent Variable Optical Attenuator

A reflective-type polymer-stabilized cholesteric liquid crystal (PSCLC) cell was demonstrated at 1⁄4 1550 nm laser wavelength. It showed a high attenuation range ( 30 dB), a low operating voltage ( 12Vrms), a highly efficient polarizationindependent behavior and flat wavelength dependence in the range of 1525–1575 nm. The combined effects of curing temperature, chiral dopant, and monomer concen...
