Abstract
Methods of operation and details of chip design to realize gray-scale capability in magneto-optic chips. Individual pixels are operated in three states by the addition of a stripped state to the usual stable magnetized states in either direction. Varying thicknesses of film are employed along with stacked identically patterend chips operated in tandem. Pixel divisions are divided into individually-addressible areas of differing sizes which can be operated in different combinations to provide varying levels of brightness through each pixel position.
