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.

A method of fabricating a micro structure includes depositing amorphous silicon over a substrate having an electric circuit at a temperature below 550° C. to form a first structure portion, wherein at least part of the first structure portion is configured to receive an electrical signal from the electric circuit.
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.

An encapsulated device includes a micro device on a substrate, a cover bonded to the substrate thereby forming a chamber to encapsulate the micro device, and a desiccant material on the cover and in the chamber. An anti-stiction material is absorbed in the desiccant material.
摘要:
Methods and apparatus are disclosed for maximizing performance of an electronic device, such as a display device. Aspects of the exemplary embodiments include operating the electronic device by adjusting power to the device to maintain a predetermined junction temperature of the device independent of the ambient temperature at which the device is operating.
摘要:
An encapsulated device includes a micro device on a substrate, a micro chamber that encapsulates the micro device on the substrate; and a layer of hermetic-sealing material that provides at least some degree of hermeticity on one or more outer surfaces of the micro chamber to at least partially hermetically seal the micro device in the micro chamber.
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 method for fabricating a micro structure includes depositing a first layer of a first material over a substrate; patterning a first hard mask over the first layer; depositing a second layer of a second material over the first layer and the first hard mask; patterning a second hard mask over the second layer; and selectively removing the first material and the second material not covered by any of the first mask and the second mask to produce over the substrate the micro structure having a first structure portion having a first height and a second structure portion having a second height.
摘要:
A high contrast spatial light modulator for display and printing is fabricated by coupling a high active reflection area fill-ratio and non-diffractive micro-mirror array with a high electrostatic efficiency and low surface adhesion control substrate.
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.
