Ferroelectric Liquid Crystal Mixtures Containing Chiral Pyranose Compounds for Response-Voltage Minimum Mode

Abstract

Ferroelectric liquid crystal (FLC) materials for the response-voltage minimum (τ– V min ) mode were developed by doping novel chiral pyranose compounds into achiral host materials with negative dielectric anisotropy. The chiral pyranose derivatives, wherein three chiral centers and a trifluoromethyl group were fixed in the 6-membered ring, induced short τ min in the τ– V min characteristic. The developed FLC materials were driven by drive schemes for the τ– V min mode, giving short line address times.
