Title (EN) LIQUID-CRYSTALLINE MEDIUM AND LIQUID-CRYSTAL DISPLAY COMPRISING THE SAME
(FR) MILIEU CRISTALLIN LIQUIDE ET ÉCRAN À CRISTAUX LIQUIDES COMPORTANT LEDIT MILIEU
Abstract:
(EN) The invention relates to a liquid-crystalline medium, preferably having nematic phase and dielectric anisotropy of 0.5 or more, which comprises one or more compounds of formula (YX) in which the parameters have the meanings given in the text, to the use thereof in an electro-optical display, particularly in an active- matrix display based on the IPS or FFS effect, to displays of this type which contain a liquid-crystalline medium of this type, and to the use of the compounds of formula (YX) for the improvement of the transmission and/or response times of a liquid-crystalline medium which comprises one or more additional mesogenic compounds.
(FR) L'invention concerne un milieu cristallin liquide, ayant de préférence une phase nématique et une anisotropie diélectrique égale ou supérieure à 0,5, qui comporte un ou des composé(s) de formule (YX) dans laquelle les paramètres sont tels que définis dans la description, leur utilisation dans un écran d'affichage électro-optique, en particulier dans un écran d'affichage à matrice active basé sur l'effet de commutation dans le plan (IPS) ou de commutation de champ de franges (FFS), des dispositifs d'affichage de ce type qui contiennent un tel milieu cristalllin liquide, et l'utilisation des composés de formule (YX) pour l'amélioration des temps de transmission et/ou de réponse d'un milieu cristallin liquide qui comprend au moins un composé mésogène additionnel.
