Influence of BM Material Species on the Elector-optical Characteristics of LCD Cell

초록

In this paper, we report our 3D FEM study on the electro-optical characteristics of an LCD cell with respect to material species of the BM by using our commercial tool, TechWiz LCD. As exemplary cell structure in our theoretical work, the PVA (Patterned Vertical Alignment) and the Super IPS (In-plane Switching) mode cells were chosen. The simulations revealed that the Super IPS mode is more sensitive to the insertion of BM than the PVA mode cell. And 5.3% for PVA cell and 22.4% for Super IPS cell off voltage applied at pixel electrode are induced at floating metal BM, respectively.
