Analysis of capacitance-voltage characteristics for two-dimensional multi-conductor in liquid crystal displays

Abstract

The capacitance voltage characteristics for the two-dimensional multi-conductor in liquid crystal displays (LCDs) are numerically derived by the method of successive over relaxation (SOR). The nonlinear and anisotropic properties of dielectric constant in the LC cell depend on the orientation of LC molecules under the influence of inhomogeneous electric field. An LC continuum theory implemented by tensor takes elastic anisotropy and inhomogeneous electric field into consideration to calculate the two-dimensional molecule orientations and potential distribution in LCDs. The dependence of capacitance on applied voltages and the geometric of LC cell is quantitatively described, Nonlinear capacitance results in capacitive coupling which causes flicker and adversely degrades image retention in LCD.
