  • Patent number: 12261989
    Abstract: A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the display surface increases. Data layers which are sampled using an effective resolution function to determine a suitable sampling rate and rendered using hybrid rendering, such as perspective and oblique rendering, to encode light fields corresponding to each data layer. The resulting compressed, (layered) core representation of the multi-dimensional scene data is produced at predictable rates, reconstructed and merged at the light field display in real-time by applying view synthesis protocols, including edge adaptive interpolation, to reconstruct pixel arrays in stages (e.g. columns then rows) from reference elemental images.

  • Patent number: 12225797
    Abstract: A microcavity pixel design and fabrication method for an organic light emitting diode (OLED) array with a high aperture ratio suitable for a light field display. This is achieved by laterally overlapping intermediate electrodes and optical filler layers, reducing the lateral spacing. The OLED layers in the design have a uniform white OLED stack, allowing each layer to be deposited across the OLED array, simplifying fabrication. The optical path length for each subpixel's optical microcavity is optimized through the thickness of the optical filler layers, allowing the white OLED stack to be uniform, reducing fabrication complexities.

  • Patent number: 12120469
    Abstract: A multiplexed light field projector device and a multiplexed light field display to output a light field image is described. The projector has a projector base with a projection optical system configured to output light rays to form a projected image, a collimating optical system configured for collimation of the projected image light rays to form a second projected image, which is directed to a display optical system to produce a light field image. Light field projector devices or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

  • Patent number: 11968372
    Abstract: A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the plane of the display increases. Data layers are sampled using a plenoptic sampling scheme and rendered using hybrid rendering, such as perspective and oblique rendering, to encode light fields corresponding to each data layer. The resulting compressed, (layered) core representation of the multi-dimensional scene data is produced at predictable rates, reconstructed and merged at the light field display in real-time by applying view synthesis protocols, including edge adaptive interpolation, to reconstruct pixel arrays in stages (e.g. columns then rows) from reference elemental images.

  • Patent number: 11869138
    Abstract: A system and method for volume rendering a light field, wherein the light field data is subjected to a layering scheme introducing a partitioning of the hogels into subsets. Each subset corresponding to a sub-volume of the layer volume, corresponds to the sub-region of the layer. Novel partitioning of the data combined with an efficient local memory caching technique, plenoptic downsampling strategies to reduce memory bandwidth requirements and volume rendering algorithm to produce a rendered light field image. A reduction in the total number of samples required can be obtained while still maintaining the quality of the resulting image. A method is also provided to order memory accesses aligned with ray calculations in order to maximize access coherency. Real-time layered scene decomposition can be combined with surface rendering method to create a hybrid real-time rendering method that supports rendering of scenes containing superimposed volumes and surfaces.

  • Patent number: 11536878
    Abstract: A direct projection light field display comprising an array of projectors for direct projection of a light field. The overall design and incorporation of additional optics achieve the optimal light distribution and small pixel size to produce a high definition, 3D display. The architecture of the direct projection light field display has low a brightness requirement for each projector, resulting in an increased projector density, decreased system, and a decreased power requirement, while producing a high-definition light field.
