    摘要: A display system includes a coherent light source that can emit a coherent light beam, a de-speckling device configured to distort a wavefront of the coherent light beam to produce a distorted coherent light beam, and a two-dimensional array of light modulators that can selectively modulate the distorted coherent light beam to select a plurality of pixels for display.

    摘要: A wafer containing a plurality of electro-optical devices, each device being enclosed in chamber that has a translucent cover. An X-Y matrix of pairs of interconnections on the wafer are connected to the circuitry of the electro-optical devices for addressing the electro-optical devices. The pairs of interconnections extend outside of the chambers enclosing the devices to testing areas on the periphery of the wafer. Testing is done by signals applied through the interconnections while simultaneously exposing the devices to light through the translucent covers.

    摘要: Devices and methods for forming a spatial light modulator with high contrast are described. Light absorbing materials are used within a chamber that houses a spatial light modulator. The light absorbing materials absorb reflected light that is not intended for forming a part of a display image. The light absorbing material can form an aperture layer, wherein light to form the display image is transmitted through an opening in the aperture layer. An array of spatial light modulators can be within the housing and dummy spatial light modulators may be formed to enable easy alignment of the array with the opening in the aperture layer.

    摘要: A micro mirror device includes a hinge supported by a substrate and a mirror plate tiltable around the hinge. The hinge includes a length longer than 1 micron, a thickness less than 500 nanometers, and a width less than 1000 nanometers. The hinge can produce an elastic restoring force on the mirror plate when the mirror plate tilts away from an un-tilted position.
