The novel approach to the thresholdless hysteresis free switching is described. The key parameters for this mode are capacitance of the alignment/insulating layers and conductivity of the FLCs. The influence of the chemical structure of FLC on the performance of the V-shape mode is discussed. Utilizing this new approach, we constructed a cell with an inversion frequency around 1 kHz and the saturation voltage less than 4V.
An optical device for modulation of the intensity of unpolarized light was constructed. In comparison with other modulators, this apparatus allows to reduce the loses of energy of light and preserve its angular divergence. The switching time and contrast ratio of the modulator are 50microsecond(s) and 300, respectively.
