Abstract

We investigated how surface anchoring strength affects the electro-optic (EO) characteristics of a fringe-field switching (FFS) mode. Unlike IPS mode that only azimuthal anchoring mainly contributes to the EO performances, both azimuthal and polar anchoring energies play an important role such that the transmittance increases with decreasing magnitude of azimuthal energy but increasing polar anchoring energy in the FFS mode when using a LC with positive dielectric anisotropy. In addition, weak anchoring at the electrode edge may result in change in initial LC optic axis by applied voltage stress so local control of anchoring energy is proposed.
