Influence of flexoelectric effect and cell parameters on image sticking caused by residula DC voltage in FFS-mode LCD

Abstract

We discuss the image-sticking problem caused by residual DC voltage from the viewpoints of the DC offset-transmittance (D-T) property varying like a quadratic function. When flexoelectric (FE) effect exists, the bottom positions of D-T property change according to gray levels, because FE makes transmittances between positive and negative frames different. We simulated D-T property using simulation software LCD master 2D and study influence of cell parameters in DT property.
