  • Electrooptical liquid crystal system
    Patent number: 5746938
    Abstract: An electrooptical system is disclosed in which a PDLC film is positioned between 2 electrode layers. The PDLC film contains a liquid crystal mixture forming microdroplets in an optically isotropic, transparent polymer matrix. The liquid crystal mixture comprises one or more compounds of formula I ##STR1## wherein R, A.sup.1, A.sup.2, Z.sup.1, Z.sup.2, X.sup.1, X.sup.2, Q, Y and n are as herein defined, and one or more reactive liquid crystalline compounds. The PDLC film exhibits improved switching times, especially at low temperatures.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: May 5, 1998
    Assignee: Merck Patent Gesellschaft Mit Beschrankter Haftung
