Simulation studies of the Fringe-field switching mode’s electrical properties II

Abstract

The flicker phenomenon associated with Fringe Field Switching(FFS)-LCD panels has not been elucidated yet enough. Based on the liquid crystal material, alignment material layer and SiNx material layer, the flicker amplitude accordingly increases while driving the LCD. Such a phenomenon is termed as ”flicker shift” or ”Vcom drift.” In the proposed simulation study, Boltzmann distribution was applied for modeling the space charge density of the aforementioned material layers. It is observed that energy levels and ion concentrations of such material layers generate asymmetric potentials in the liquid crystal layer, which cause the flicker phenomenon.
