Abstract: A micro-display has a device chip with a transparent layer overlying one or more micro-electromechanical system devices. A transparent cover overlies the transparent layer. An index-of-refraction-matching medium is interposed between the transparent layer and the transparent cover. An index of refraction of the index-of-refraction-matching medium is substantially equal to an index of refraction of the transparent layer and the transparent cover.

Abstract: A prism assembly includes a first prism having a first front face, a first side face, and a first rear face, a second prism having a second front face parallel to the first rear face, a second side face, and a second rear face. The second prism is configured to direct a first component beam through the second side face. The prism assembly also includes a third prism having a third front face parallel to the second rear face, a third side face, and a third rear face. The third prism is configured to direct a second component beam through the third side face. The prism assembly also includes a fourth prism having a fourth front face parallel to the third rear face and a fourth rear face, the rear face being parallel to the first front face. The fourth rear face is configured to transmit a third component beam there through.

Abstract: One embodiment provides a method that includes displaying Boolean combinations of two or more bit planes.

Abstract: One embodiment of a viewing cone adjustment system includes a projection lens that defines a projection lens optical axis adjustably offset from a viewing screen optical axis, and an image source device that defines an image source optical axis adjustably offset from the projection lens optical axis.

Abstract: For each bit plane of a plurality of bit planes of a pixel, a first spatial light modulator is modulated in accordance with a value of the bit plane. For each bit plane of at least one of the plurality of bit planes of the pixel, a second spatial light modulator is modulated in accordance with the value of the bit plane as logically OR'ed with values of corresponding bit planes of neighboring pixels to the pixel.

Abstract: An optical assembly for a projection system includes an objective lens and a retro-focus lens. Then objective lens and retro-focus lens share one or more lens elements. A method of projecting an image comprises directing light from a light source to one or more modulators and projecting a modulated light beam using an optical assembly that includes an objective lens and a retro-focus lens that share one or more lens elements.

Abstract: A display system is provided that includes a spectral separator configured to separate multispectral light into a plurality of light bands, and a homogenizing element configured to homogenize at least one separated light band.

Abstract: A projector includes an array of micromirror light modulators and a projector light source for generating an illumination light beam along an optical path. An elongated rectilinear illumination aperture is defined at a first location along the optical path, with one or more elongated regions having a long dimension parallel to the axis. An elongated rectilinear pupil aperture is defined at an output pupil with one or more elongate pupil regions having a long dimension parallel to the axis.

Abstract: An inkjet printer printhead has a layering of a flexible polymer tape, a patterned barrier material that is acting as an adhesive as well as ink channels, and a substrate that has a plurality of ink expulsion devices. Each of the ink propulsion devices is aligned with an orifice hole ablated in the flexible polymer tape where the ink expels and patterns the medium beyond. To keep adhesives and encapsulants required in the assembly of the inkjet printer printhead out of the critical ink channel area near the orifice holes, fluid accumulation channels are ablated into the flexible polymer tape in a strategic location between the adhesive bead and the ink channel. These accumulation channels function as both a diversion a containment point for the excess flow of adhesive.
