摘要: A supertwisted nematic liquid-crystal 3pi/2-cell with fast response and high contrast ratio as prepared. We investigated the dynamic mechanism of the 3pi/2-cell by theoretical analyst,., and numerical calculation. We found that, Unlike the TN [C. Z. van Doom: J. Appl. Phys 46 (1975) 3738: D. W. Berreman: J. Appl. Phys, 46 (1975) 3740] homogeneous [P. J. Bos et al.: SID 83 Dig., 1983, p. 30] and CHLC [S.-H. Chen et al,: Appl. Phys. Lett. 75 ( 1999) 3491] cells, the flow-induced viscous torque helps to Pull back the liquid-crystal molecules after the applied field is switched off and thus accelerates the relaxation process in the super-twisted nematic liquid-crystal 3pi/2-cell. Furthermore. using the liquid crystal of high optical anisotropy, a fast response of 2 ms was obtained.
