Investigation of Flexoelectric Effect in Vertically-Aligned In-Plane-Switching Mode by Low Frequency Driving

摘要

Due to the inhomogeneous electric field, liquid crystal molecules reveal splay deformation in vertically-aligned in-plane-switching mode. The flexoelectric effect from the splay is confirmed by fast CCD images. We introduce a model to explain the mechanism of such phenomenon and to determine the sign of flexoelectric coefficient.
