The influence of the data signal on transmission characteristics of LCD cells
In this paper, we report our preliminary study about the influence of data signal on the optical properties of LCD cell which is operated at vertical alignment (VA) mode. The VA cell employed in this study has a size of 88 x 264 mu m(2) with a cell gap of 4 pin. In order to analyze the optical crosstalk between the data signals, we employed finite element method (FEM) for calculating the LC director distributions and 2 x 2 extended Jones method for optical transmission. Our simulation revealed that the voltage discrepancy between data signal and pixel electrode voltage is the main cause for the reduction of brightness as well as the generation of flickers.
