Blue Phase Liquid Crystals Using Photocurable Monomers for Nano-structured Materials

Blue-Phase Liquid Crystals for Projection Displays

A projection display using blue-phase liquid crystal (BPLC) is proposed. The fast-response BPLC enables field sequential projection display with suppressed color breakup. Methods for reducing the operating voltage are also discussed. Author

Diluter Effects on Large Dielectric Anisotropy Blue Phase Liquid Crystals

We have investigated diluter effects on the Debye relaxation frequency, and electro-optics of polymer-stabilized blue phase liquid crystals (BPLC). The relaxation frequency can be increased by adding a small amount of diluters, which benefits high frequency operation of BPLC. Some diluters significantly decrease the BPLC response time while maintaining similar Kerr constant. Author

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...

Optical rotatory power of polymer-stabilized blue phase liquid crystals

Macroscopically, a polymer-stabilized blue phase liquid crystal (BPLC) is assumed to be an optically isotropic medium. Our experiment challenges this assumption. Our results indicate that the optical rotatory power (ORP) of some nano-scale double-twist cylinders in a BPLC composite causes the polarization axis of the transmitted light to rotate a small angle, which in turn leaks through the cro...
