摘要： The disclosure describes various aspects of a partial light field display architecture. In an aspect, a light field display includes multiple picture elements (e.g., super-raxels), where each picture element includes a first portion having a first set of light emitting elements, where the first portion is configured to produce light outputs that contribute to at least one a two-dimensional (2D) view. Each picture element also includes a second portion including a second set of light emitting elements (e.g., sub-raxels) configured to produce light outputs (e.g., ray elements) that contribute to at least one three-dimensional (3D) view. The light field display also includes electronic means configured to drive the first set of light emitting elements and the second set of light emitting elements in each picture element. The light field display can also dynamically identify the first portion and the second portion and allocate light emitting elements accordingly.

摘要： Disclosed herein is methods and systems for providing different views to a viewer. One particular embodiment includes a method including providing, to a neural network, a plurality of 2D images of a 3D object. The neural network may include a signed distance function based sinusoidal representation network. The method may further include obtaining a neural model of a shape of the object by obtaining a zero-level set of the signed distance function; and modeling an appearance of the object using a spatially varying emission function. In some embodiments, the neural model may be converted into a triangular mesh representing the object which may be used to render multiple view-dependent images representative of the 3D object.

摘要： A display device includes a substrate includes a first emitter and a second emitter thereon. The first emitter includes a first lower active quantum well (QW) region that has a first emission spectrum spanning a first spectral range. The second emitter includes (i) an upper active QW region that has a second emission spectrum spanning a second spectral range that is distinct from the first spectral range, (ii) a second lower active QW region having the first emission spectrum and being located between the upper active QW region and the substrate, and (iii) a barrier layer between the second lower active QW region and the upper active QW region for suppressing emission of the second lower active QW region.

摘要： The disclosure describes aspects of a display processing circuitry. In an aspect, one or more displays that support multiple views include one or more arrays of pixels, one or more backplanes, and a processing circuitry configured to receive one or more data streams, control processing of the data streams based on policies from which to select a mode of operation, each mode of operation defining which rays of light the arrays of pixels in the displays are to contribute to generate a particular view or views and the tasks to be performed by the processing circuitry to modify the data streams accordingly. The processing circuitry further provides signaling representative of the modified data streams to the arrays of pixels through a circuit configuration of the backplanes for the arrays of pixels to contribute the rays that will to generate the particular view or views. A corresponding method is also described.

摘要： A multiview autostereoscopic display includes a display area including an array of angular pixels, an eye tracker, and a processing system. Each angular pixel emits color that varies across a field of view of that angular pixel. The array of angular pixels displays different views in different viewing zones across the field of view of the display. The eye tracker detects the presence of the eyes of at least one viewer within specific viewing zones and produces eye tracking information including locations of the detected eyes within the specific viewing zones. The processing system renders a specific view for each detected eye based upon the location of the detected eye within the viewing zone with detected eyes, and generates control information for the array of angular pixels to cause the specific view for each detected eye to be displayed in the viewing zone in which that eye was detected.

摘要： The disclosure describes various aspects of monolithic integration of different light emitting structures on a same substrate. In an aspect, a device for light generation is described having a substrate with one or more buffer layers made a material that includes GaN. The device also includes light emitting structures, which are epitaxially grown on a same surface of a top buffer layer of the substrate, where each light emitting structure has an active area parallel to the surface and laterally terminated, and where the active area of different light emitting structures is configured to directly generate a different color of light. The device also includes a p-doped layer disposed over the active area of each light emitting structure and made of a p-doped material that includes GaN. The device may be part of a light field display and may be connected to a backplane of the light field display.
