摘要：
A pi/2 and 5 pi/2 twist bistable nematic liquid crystal cell is optimized in optics by a parameter space approach. The cell possesses good contrast ratio, a preferable d Delta n value, a wide viewing angle, and black-white display. Three switching wave forms can be used to switch the cell between pi/2 and 5 pi/2 twist states. Controlling the selection voltage amplitude can provide gray scales for the cell.
