Projection display system including a high fill ratio silicon spatial light modulator

A projection display system comprising:

• a light source adapted to provide an illumination beam;
• a spatial light modulator including a plurality of micro-mirrors controllably deflectable between a first deflection angle and a second deflection angle, wherein each micro-mirror of the plurality of micro-mirror is associated with a pixel of an image and wherein each micro-mirror comprises:
• one or more electrodes provided on a support substrate;
• a hinge device coupled to the support substrate, wherein the hinge device comprises silicon material;
• a mirror post coupled to the hinge device and extending away from the support substrate;
• and
• a mirror plate coupled to the mirror post and overlying the one or more electrodes;
• illumination optics adapted to direct the illumination beam to the spatial light modulator;
• optics provided in a projection path lying along the first deflection angle and adapted to project the image on a projection surface;
• optics provided in a light dump path lying along the second deflection angle and adapted to reduce an intensity of light propagating along the light dump path;
• and
• a color wheel positioned between the light source and the spatial light modulator, wherein the color wheel is operative to provide a sequential train of optical pulses, each optical pulse characterized by a different wavelength.
