  • Oligosiloxane modified liquid crystal formulations and devices using same
    Patent number: 8821992
    Abstract: A liquid crystal formulation is described. The liquid crystal formulation comprises a first oligosiloxane-modified nano-phase segregating liquid crystalline material; and at least one additional material selected from a second oligosiloxane-modified nano-phase segregating liquid crystalline material, non-liquid crystalline oligosiloxane-modified materials, organic liquid crystalline materials, or non-liquid crystalline materials, wherein the liquid crystal formulation has an I?SmA*?SmC* phase transition, with a SmC* temperature range from about 15° C. to about 35° C., a tilt angle of about 22.5°±6° or about 45°±6°, a spontaneous polarization of less than about 50 nC/cm2., and a rotational viscosity of less than about 600 cP. Devices containing liquid crystal formulations are also described.
    Type: Grant
    Filed: October 26, 2007
    Date of Patent: September 2, 2014
    Assignees: Dow Corning Corporation, Cambridge Enterprise Ltd.
    Inventors: Jonathan Paul Hannington, Terry Victor Clapp, Fumito Nishida, Russel Keith King, Omar Farooq, Martin Grasmann, William Alden Crossland, Harry James Coles, Anthony Bernard Davey, Huan Xu, Oliver Hadeler, Mykhaylo Pivnenko
