Abstract

A solid state light modulator apparatus for displaying images represented by video signals. The system includes an array of semiconductor devices having electrodes which extend over the tops of their respective devices. The devices are used, in conjunction with related circuitry, for applying sampled video signals to the electrodes. The resulting charge pattern deforms a concuctive/reflective layer, and the deformations are converted to a viewable image by an optical system. The electrodes are divided into separated fingers which decreases the effective grating line spacing of the light modulator and accordingly increases resolution. Also, the electrodes are at two different levels, and the spurious light immunity of the light modulator is improved.
