Three types of electrically controlled light scattering distinguished on the physical mechanism were studied in monomeric FLC compositions at different boundary conditions and electrical pulse regimes. The total time of scattering switching on and switching off was less than 150, 250 and 500 us for different scattering types. They are rather fast to be used in a volumetric screen based on a stack of 30-100 light-scattering shutters.

Abstract— Three types of light‐scattering effects distinguished by physical mechanisms were studied in detail in monomeric ferroelectric liquid‐crystal (FLC) compositions at different boundary conditions and electrical pulse regimes. The total time of the scattering switching on and switching off is less than 150, 250, and 500 μsec at ±50 V for different scattering types in helix and non‐helix FLCs. They are quite fast, and FLC cells are quite transparent and were used in a stack of 30–100 light‐scattering shutters for a volumetric screen of a 3‐D display.
