Abstract: A near eye display system having an image display panel, a prism assembly comprising a first and second element and a structure such as a eye wear glasses frame. The front and rear surfaces of the first and second elements are aligned and bonded to form the prism assembly. A partially-reflective coating is applied to the interface of the first and second elements to define a beam-splitter interface. The image display panel is disposed near an upper optical region such as a refracting surface of the first element. The lower edge of the second element opposite the beam-splitter interface is a coated reflective surface mirror. The display panel, the optical region and the optically reflective surface are configured to provide compactness and to avoid the break of symmetry. The system accommodates large inter pupil distance (IPD) variation and left/right eye scanning motion.

Abstract: A dual-mode augmented/virtual reality near-eye wearable display for use with a curved lens element. The lenses are provided with one or more transparent waveguide elements that are disposed within the thickness of the lenses. The waveguide elements are configured to couple display images directly from image sources such as emissive display imagers to an exit aperture or plurality of exit aperture sub-regions within a viewer's field of view. In a preferred embodiment, a plurality of image sources are disposed on the peripheral surface of the lenses whereby each image source has a dedicated input image aperture and exit aperture sub-region that are each “piecewise flat” and have matched areas and angles of divergence whereby a viewer is presented with the output of the plurality of image source images within the viewer's field of view.

Abstract: Emissive micro-pixel spatial light modulators with non-telecentric emission are introduced. The individual light emission from each multi-color micro-scale emissive pixel is directionally modulated in a unique direction to enable application-specific non-telecentric emission pattern from the micro-pixel array of the emissive spatial light modulator. Design methods for directionally modulating the light emission of the individual micro-pixels using micro-pixel level optics are described. Monolithic wafer level optics methods for fabricating the micro-pixel level optics are also described. An emissive multi-color micro-pixel spatial light modulator with non-telecentric emission is used to exemplify the methods and possible applications of the present invention: ultra-compact image projector, minimal cross-talk 3D light field display, multi-view 2D display, and directionally modulated waveguide optics for see-through near-eye displays.

Abstract: A III-V light emitting device with pixels (mesa regions) specifically designed to enable lower cost through layer vias is disclosed for reduced cost of manufacture of the device. Reduction of cost of manufacture is achieved by having non-uniform width trench regions formed during pixel etch for the multi-pixel array part of the device. Through-layer vias are specifically formed in the wider part of the trench regions using cheaper lithography toolset enabled by the larger via critical dimension achievable in the wider part of the trench regions (as compared to narrow part of the trench regions). Larger via critical dimension enables improved electrical (and consequently optical) performance of the device due to better overlay control as well as lower via resistance.

Abstract: Methods for virtual clothes fitting when shopping online are presented. The online shopper prepares and keeps a 3D volumetric scan or point cloud of their body. Shoppers upload their 3D volumetric body scan to an online store. The online store stores the 3D volumetric scan of the clothing it offers for sale on their online shop. The online store has the processing capabilities to fit the 3D body scan provided by the shopper with the 3D volumetric scan of clothing it offers for sale on their online shop. Once the 3D volumetric data of the offered clothing item is digitally fitted by the online store on the 3D volumetric scan of the offered clothing item, the 3D volumetric data of the offered clothing fitted on the created “Virtual Mannequin” of the shopper is sent back to shopper to view and examine.

Abstract: A wearable display device includes a visual access operating system (vuOS) that can interface with multiple computing platforms. The vuOS enables concurrent visual interface between the multiple computing platforms and a user and performs context switching between the multiple computing platforms in response to either a computing platform visual access request or a user's selection prompt. The multiple computing platforms are each assigned a user selected visual access slot that occupies a selected segment of the user field of view (FOV) visually accessible by the wearable display system. At any given time one of the multiple computing platforms visual access slots is brought onto the user's gaze zone in the FOV while some of the other computing platforms visual access slots are assigned to the peripheral vision zone and other computing platforms are assigned visual access attention request access slots displayed at a visual attention zone within the user's viewable portion of the wearable display FOV.

Abstract: An emissive Solid State Imager (SSI) comprised of a spatial array of digitally addressable multicolor micro pixels. Each pixel is a micro optical cavity comprising multiple photonic layers of blue-violet semiconductor light emitting diode. One of the photonic layers is used to generate light at the blue primary of the SSI. Two of the photonic layers are used to generate violet-blue excitation light which is converted with associated nanophosphors layer into the green and the red primaries of the SSI. The light generated is emitted perpendicular to the plane of the imager device via a plurality of vertical optical waveguides that extract and collimate the light generated. Each pixel diode is individually addressable to enable the pixel to simultaneously emit any combination of the colors associated with its multicolor nanophosphors converted semiconductor light emitting diode at any required on/off duty cycle for each color.
