Abstract
Two independently adjustable fields are employed to control the optical condition of a dielectrically anisotropic liquid crystal. One of the fields E.sub.x may be perpendicular to the initial direction of the liquid crystal molecules and the other E.sub.y parallel thereto. In an array, the E.sub.x field may be employed to select the location in a liquid crystal display that it is desired to excite and the E.sub.y field to control the intensity of the excitation. In one mode of operation, use is made of a newly discovered nonlinear effect for amplifying in a later time period an optical disturbance introduced into the liquid crystal during an earlier time period.
