Thresholdless Electro-Optical Property in Quasi Homogeneous and Homeotropic Liquid Crystal Cells Using Weak Anchoring Surfaces

Abstract

Liquid crystal director distributions between strong and weak polar anchoring surfaces in hybrid aligned cells are numerically analyzed. When the anchoring is a critical one, homogeneously or homeotropicly liquid crystal alignment can be obtained. Such cells have no threshold voltage and a driving voltage can be reduced less than 0.5 volt.
