  • Title: Electrically switched color with polymer-stabilized blue-phase liquid crystals.
    Author: Lu SY, Chien LC.
    Journal: Opt Lett; 2010 Feb 15; 35(4):562-4. PubMed ID: 20160818.
    Abstract:
    We report an electrical-field switched color device using a polymer-stabilized blue-phase (PSBP) liquid crystal in which the Bragg-reflected color of the blue phase (BP) can be switched to reflect a second color. The phase-separated three-dimensional polymer network transcribes the cubic structure of a BP liquid crystal and restrains the deformation of cubic lattice by the external electric field. The new wide-range electric-field switched colors with PSBP may be an important step toward ecofriendly color reflective displays.
