Active-matrix-addressed deformable elastomer layers with schlieren optics. New and improved technologies for an old light-valve concept

Monolithic active matrices for light-valve application were fabricated using silicon CMOS technology. Features are signal-handling capabilities of 30 V, optimized surface planarity, and excellent light immunity. The on-chip addressing circuitry exceeds television requirements. Results for small matrices are presented; larger versions (up to standard television) are under development.
