  • Polymer network stabilized flexoelectric polarization
    Patent number: 9239494
    Abstract: A liquid crystal device comprising a first substrate; a second substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate, the liquid crystal layer comprising a nematic liquid crystal material and a polymer network. The polymer network is anchored to said first substrate and is configured to alternatingly induce splay deformation and bend deformation of the nematic liquid crystal material along a line parallel with the first substrate. Hereby, the relaxation time ?fall of the liquid crystal device is reduced.
    Type: Grant
    Filed: November 9, 2011
    Date of Patent: January 19, 2016
    Inventors: Lachezar Komitov, Gurumurthy Hegde, Seung Hee Lee
