ABSTRACT:
A bistable electrostatic light valve display in which a movable electrode is disposed opposite a fixed electrode and is biased to move in a preferred direction upon application of an electric field across the electrodes to produce a light valve or light shutter. In one embodiment, the movable electrode is restrained at one end and coils about the fixed end in a preferential roll direction. The bias is achieved by inducing anisotropic stress or anisotropic stiffness. In another embodiment, the moveable electrode is restrained at both ends and is biased upwardly by anisotropic stress or stiffening.
