To produce analog grey shades in our special construction SSFLC matrix display, different "low voltage", "stopped writing" and "hampered writing" addressing waveforms have been tested in computer simulations and experiments. Three phenomena limit the achievable results : the first is addressing hysteresis, subject of our previous paper, the second is the crosstalk from data intended for other pixels, the third is characteristic switching pulse area variations due to cell temperature or thickness variations. We present here computer simulations of the two latter effects, for a range of different addressing modes. For the faster addressing modes, based on liquid crystal dielectric biaxiality, data waveforms are necessary featuring constant rms voltage, de balance and crosstalk compensation. New technique are here introduced making use of such data waveforms in place of the previous ones, based on amplitude or pulse-position modulation.
