Effects of Step-Coverage On Parasitic Capacitances: Does it affect the accuracy of your FEM calculation?

초록

In this paper, we report the influences of the step-coverage on the effective capacitances in LC cell. In this work, we have analyzed the conven-tional TN mode LC cell by using the numerical simulator, TechWiz LCD. In order to calculate ef-fective capacitances, the energy method is used. As a result, we found that the step-coverage structure causes the parasitic capacitance be-tween the data line and the pixel electrode to be about 18 times as large as the parasitic capaci-tance resulted from a normal planar structure
