Аннотация:We present a new type of bistable electro-optical device based on ferroelectric S c * liquid crystals exhibiting a short pitch (0.43 µm) and a large spontaneous polarization (50···150 nC/cm 2 ). Features of the new short pitch bistable ferroelectric liquid crystal displays (SBF-LCDs) which are based on the effect are: short switching times (25 µs) at room temperature using 2 µm cell gap and 30 V bipolar pulses; contrast ratios>35; multiplexing ratios>1000; large on-state brightness due to a large memory switching angle of 40° as well as a weak temperature dependence of both, response time and memory tilt angle.
