Abstract
V-shaped electro-optical response is shown, both theoretically and experimentally, to be an inherent property of a deformed-helix ferroelectric liquid-crystal cell (DHFLC) under a special choice of the applied rectangular alternating-electric-field waveform, frequency, and cell geometry. In contrast to other known V-shaped ferroelectric liquid-crystal (FLC) modes, the discovered V-shaped switching is observed in a broadband frequency range including 1 kHz, and not at a certain characteristic frequency. This type of V-shaped switching allows for a drastic increase in the operating frequency of field-sequential- color (FSC) LCD cells in comparison with fast nematic liquid-crystal (NLC) modes.
