“…For smectic liquid crystals, the description of the dynamic behavior is usually based on a onedimensional description [7,8,10,13]. However, the real behavior is more complicated, because switching is often inhomogeneous, through domain wall motion.…”

“…The importance of ions in smectic materials has been recognized early on [7][8][9] and there are many reports in the literature about experimental work and theoretical simulations of ion transport [7][8][9][10][11]. In smectic materials the electric field generated by the ions can play an important role in the switching and the bistability of smectic devices.…”

In SSFLC and AFLC devices, the voltage over the liquid crystal is not only determined by the applied voltage, but also by the separation of ions and the spontaneous polarization. The motion of ions and the switching of the spontaneous polarization are therefore interfering phenomena. A simplified model for ion transport and switching of polarization is introduced which is able to explain the shift in apparent threshold voltage and the variation of the hysteresis width.
