Abstract

A spatial light modulator for use in projection display applications is provided. The spatial light modulator includes a substrate including a plurality of electrically active circuits and an electrode layer electrically coupled to at least one of the plurality of electrically active circuits. In one embodiment, the electrode layer includes a semi-continuous layer with at least one optical path. The spatial light modulator also includes a shielding layer electrically isolated from the electrode layer and disposed between the substrate and the plurality of electrically active circuits and an electrical connector coupling the shielding layer to a reference potential. In a specific embodiment, the shielding layer of the spatial light modulator converts incident light energy to electrical current and routes the current back to a source. In another specific embodiment, the shielding layer converts electrical field disturbance to electrical current and routes the current back to a source.
