A macro-circuit equivalent model for ferroelectric liquid crystal(FLC)is proposed.The model includes both effects of ferroelectric torque and dielectric torque and is utilized to simulate the switching response and memory behavior of a single FLC cell.Simulation results show that the delay time has a minimum while increasing the amplitude of drive voltage and the amplitude of bipolar pulses should be controlled within a certain range to realize the memory behavior.Also the switching angle is successfully enhanced to the reference value of 22.5°by adopting"AC stabilization"addressing method.
