Abstract
A solid state light modulator apparatus is disclosed 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 conjuction with related circuitry, for applying sampled video signals to the electrodes. The resulting charge pattern deforms a conductive/reflective layer, and the deformations are converted to a viewable image by an optical system. The electrodes are divided into separate fingers which decreases the effective grating line spacing of the light modulator and accordingly increases resolution. Electrodes of the array have at least three electrically connected fingers such that at least one of the fingers is interleaved with fingers of an electrode in a row above in said array and at least another of said fingers is interleaved with fingers of an electrode in a row below in said array.
