  • Liquid crystalline medium and electro-optical device
    Patent number: 12215267
    Abstract: The new media exhibit a ferroelectric nematic phase preferably at ambient temperature. They preferably comprise one or more compounds selected from the group of compounds of formulae IA, IB and IC, in which the variable groups have the meanings indicated in the text and in the claims. Use of the media for providing ferroelectric nematic materials and a method of operation of an electro-optical device are presented. The media may be useful for energy-saving displays and electrical appliances.
    Type: Grant
    Filed: November 30, 2021
    Date of Patent: February 4, 2025
    Assignee: MERCK PATENT GMBH
    Inventors: Matthias Bremer, Atsutaka Manabe, Martin Kraska

  • FERROELECTRIC NEMATIC LIQUID CRYSTALLINE MEDIUM
    Publication number: 20240002727
    Abstract: The new LC media exhibit a ferroelectric nematic phase at ambient temperature. They comprise at least one or more compounds selected from each of formula IA, of formula IB and of the group of formulae IC-1/IC-2/IC-3, in which the variable groups have the meanings indicated in the text and in the claims. The mixtures are useful for electro-optics, electronics, electro-mechanic and other applications for materials with very high dielectric permittivity and other energy-saving applications.
