ABSTRACT:
A display system includes a light source and a first optical system coupled to the light source and adapted to provide an illumination beam along an illumination path. The display system also includes a spatial light modulator positioned in the illumination path. The spatial light modulator includes a semiconductor substrate including a plurality of electrode devices and a hinge structure coupled to the semiconductor substrate. The hinge structure includes silicon material. The spatial light modulator also includes a mirror post coupled to the hinge structure and extending to a predetermined distance from the semiconductor substrate and a mirror plate coupled to the mirror post and overlying the plurality of electrode devices. The display system further includes a second optical system coupled to the spatial light modulator and adapted to project an image onto a projection surface.
