Title (EN) LIQUID CRYSTALLINE MEDIUM
(FR) MILIEU CRISTALLIN LIQUIDE
Abstract:
(EN) The invention relates to dielectrically positive liquid crystalline media comprising a compound of formula (I) wherein R1 denotes alkenyl having 2 to 12 C atoms, and X1 denotes H, F or alkyl having 1 to 6 C atoms, and to liquid crystal displays comprising these media, especially to active matrix displays and in particular to TN, FFS and IPS mode displays.
(FR) L'invention concerne des milieux cristallins liquides diélectriquement positifs comprenant un composé de formule I, (I) dans laquelle R1 indique un alcényle contenant de 2 à 12 atomes de C et X1 indique H, F ou alkyle contenant de 1 à 6 atomes de C. L'invention concerne également des affichages à cristaux liquides comprenant ces milieux, en particulier des affichages à matrice active et en particulier des affichages à mode de nématique en hélice (TN), de commutation de champ de franges (FFS) et de commutation dans le plan (IPS).
