    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 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. The wearable display vuOS further allocates to each of the multiple computing platforms a physical interface connection having an interface throughput that is commensurate with their assigned visual slot size and position within the user field of view (FOV) visually accessible by the wearable display system.

    Abstract: Disclosed herein are multi-layered optically active regions for semiconductor light-emitting devices (LEDs) that incorporate intermediate carrier blocking layers, the intermediate carrier blocking layers having design parameters for compositions and doping levels selected to provide efficient control over the carrier injection distribution across the active regions to achieve desired device injection characteristics. Examples of embodiments discussed herein include, among others: a multiple-quantum-well variable-color LED operating in visible optical range with full coverage of RGB gamut, a multiple-quantum-well variable-color LED operating in visible optical range with an extended color gamut beyond standard RGB gamut, a multiple-quantum-well light-white emitting LED with variable color temperature, and a multiple-quantum-well LED with uniformly populated active layers.

    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.
