Articles you may be interested in Dynamic response of a polymer-stabilized blue-phase liquid crystal Electro-optics of polymer-stabilized blue phase liquid crystal displays Appl. Reversible optical control of transmittance in polymer/liquid crystal composite films by photoinduced phase transition J. Polymer-stabilized blue-phase liquid crystal (BPLC) comprising fluorinated compounds with high resistivity and photochemical stability is demonstrated. The Kerr constant, driving voltage, and response time of this BPLC are measured using an in-plane switching liquid crystal cell. At 20 C, the measured total response time is faster than 0.7 ms and Kerr constant is 2 nm/V 2. This fluorinated BPLC material is a promising candidate for next-generation photonic and display devices, because it can be used in active matrix addressed devices. V C 2014 AIP Publishing LLC.

متن کاملA reflective polarizer-free electro-optical switch using dye-doped polymer-stabilized blue phase liquid crystals.
We demonstrate a reflective polarizer-free electro-optical switch using dye-doped polymer-stabilized blue phase liquid crystals (DDPSBP-LC). At the voltage-off state, the dye molecules and liquid crystals form the structure of the double twist cylinders. As a result, the DDPSBP-LC is in dark state due to the combination of Bragg reflection and light absorption. At the voltage-on state, the blue...

The polymer stabilized liquid crystal (PSLC) film is a relatively novel electro-optical material, which is generally obtained by dissolving a small amount of a bifunctional photoreactive monomer in a low molecular mass liquid crystal. In this paper, the PSLC films were prepared with photoreactive biphenyl methacrylate monomers by photopolymerization induced phase separation. The effects of liqu...

Polymer-stabilized blue phase liquid crystals (PS-BPLC) have become an increasingly important technology trend for information display and photonics applications. BPLCs exhibit several attractive features, such as reasonably wide temperature range, submillisecond gray-to-gray response time, no need for alignment layer, optically isotropic voltage-off state, and large cell gap tolerance. However...

We report a polymer-stabilized blue-phase liquid crystal (PSBPLC) cured with a visible laser in an in-plane-switching (IPS) cell. Its electro-optic properties are compared with those of a conventional PS-BPLC cured by ultraviolet (UV) light. Besides, a PS-BPLC grating is fabricated using visible-laser holography. Author
