An improved equivalent circuit model for ferroelectric liquid crystal (FLC) in which the anisotropic electro-optical properties are presented is proposed to simulate the AC stabilization technology.The coupling effects of electric fields to dielectric tensor as well as the surface anchoring forces due to alignment layers are included in the model by equivalent current sources to make it has the capability in optical response prediction and dynamic analysis when dielectric anisotropy of FLC is of a relatively high value.Optical responses in cases of positive anisotropy and negative anisotropy

and with AC stabilization technology are displayed

and the dielectric torque

ferroelectric torque and polarization reversal current are given.The simulation results indicate a good quantitative agreement with the theoretical analysis and the published results.
