Title (EN) HETEROCYCLIC LIQUID CRYSTAL COMPOSITION, REVERSE-MODE POLYMER DISPERSED LIQUID CRYSTAL ELEMENT, AND SELECTIVELY DIMMABLE DEVICE
(FR) COMPOSITION DE CRISTAUX LIQUIDES HÉTÉROCYCLIQUES, ÉLÉMENT À CRISTAUX LIQUIDES DISPERSÉS DANS UN POLYMÈRE EN MODE INVERSE, ET DISPOSITIF À INTENSITÉ SÉLECTIVEMENT VARIABLE
Abstract:
(EN) Described herein are heterocyclic liquid crystal compositions that can allow for the adjustment of their refractive indices by the application of an electric field. In addition, selectively dimmable reverse-mode polymer dispersed liquid crystal (PDLC) elements and devices using these compositions are also described, which are transparent when no voltage is applied and opaque when a voltage is applied.
(FR) La présente invention concerne des compositions de cristaux liquides hétérocycliques qui peuvent permettre l'ajustement de leurs indices de réfraction par l'application d'un champ électrique. De plus, l'invention concerne également des éléments à cristaux liquides dispersés dans un polymère (PDLC) en mode inverse à intensité sélectivement réglable et des dispositifs utilisant ces compositions, qui sont transparents lorsqu'aucune tension n'est appliquée et opaques lorsqu'une tension est appliquée.
