  • Patent number: 10448030
    Abstract: A compression method for high-resolution light field display is disclosed for applications in which computer memory constraints and latency are critical. The disclosed compression algorithm takes advantage of the 3D structure of a light field to compress the raw light field information with a fixed compression ratio and simple decoding instructions. The compressed high-resolution light field achieves a reduced bandwidth with acceptable quality, and is packed in a way that can be transmitted using common interfaces. In a preferred embodiment, the compression algorithm is used as a post-processing stage after light field information acquisition or after rendering. In a further preferred embodiment, the compression algorithm is incorporated into the acquisition or rendering procedure to reduce memory and rendering processing. These and further embodiments generate a compressed light field with all information required for direct display.

  • Patent number: 10396240
    Abstract: A III-nitride semiconductor light emitting device incorporating n-type III-nitride cladding layers, indium containing III-nitride light emitting region, and p-type III-nitride cladding layers. The light emitting region is sandwiched between n- and p-type III-nitride cladding layers and includes multiple sets of multi-quantum-wells (MQWs). The first MQW set formed on the n-type cladding layer comprises relatively lower indium concentration. The second MQW set comprising relatively moderate indium concentration. The third MQW set adjacent to the p-type cladding layer incorporating relatively highest indium concentration of the three MQW sets and is capable of emitting amber-to-red light. The first two MQW sets are utilized as pre-strain layers. Between the MQW sets, intermediate strain compensation layers (ISCLs) are added. The combination of the first two MQW sets and ISCLs prevent phase separation and enhance indium uptake in the third MQW set.

  • Patent number: 10373830
    Abstract: An electromagnetic wave irradiation apparatus and methods to bond unbonded areas in a bonded pair of substrates are disclosed. The unbonded areas between the substrates are eliminated by thermal activation in the unbonded areas induced by electromagnetic wave irradiation having a wavelength selected to effect a phonon or electron excitation. A first substrate of the bonded pair of substrates absorbs the electromagnetic radiation and a portion of a resulting thermal energy transfers to an interface of the bonded pair of substrates at the unbonded areas with sufficient flux to cause opposite sides the first and second substrates to interact and dehydrate to form a bond (e.g., Si—O—Si bond).

  • Publication number: 20190222821
    Abstract: A compressed light field imaging system is described. The light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering. The light field is encoded and transmitted to the display. The 3D display directly reconstructs the light field and avoids data expansion that usually occurs in conventional imaging systems. The present invention enables the realization of full parallax 3D compressed imaging system that achieves high compression performance while minimizing memory and computational requirements.

  • Publication number: 20190088708
    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.
