  • Electrically Tunable Reflection Color Of Chiral Ferroelectric Nematic Liquid Crystals
    Publication number: 20240110100
    Abstract: The present invention relates to a doped ferroelectric nematic liquid crystal having a chirality-induced stabilization of the polar nematic order, improved relaxation time for electro-optical switching, and selective reflection in the visible wavelength that is reversibly tunable. The ferroelectric nematic liquid crystal is doped with a chiral dopant selected from the group benzoic acid, 4-hexyl-,4-[[(1-methylheptyl)oxy]carbonyl]phenyl ester (ZLI811) and BDH1281.

  • OPTICAL DIMMING DEVICES WITH CHIRAL FERROELECTRIC NEMATIC LIQUID CRYSTAL
    Publication number: 20240094584
    Abstract: An optical device includes a first electrode and a medium that includes ferroelectric liquid crystals and chiral dopants. The medium is located adjacent to the first electrode. The optical device may also include a second electrode distinct and separate from the first electrode. The optical device may be used as an optical dimming device, controlling an amount light passing through the optical device based on a voltage gradient provided to the optical device.
