摘要： A light emission system includes an array of micro light-emitting diodes (microLED)s. The array of microLEDs includes a semiconductor substrate, a prep layer formed on at least a portion of the semiconductor substrate, and an active region formed on the prep layer. The array of microLEDs also include a plurality of thick sub-structures forming an array on the active region, and a plurality of thin sub-structures formed on the active region, each one of the thin sub-structures being located between each adjacent pair of thick substructures. Each one of the thick sub-structures defines a shape and size of a corresponding one of the microLEDs. Each one of the thin sub-structures is configured for preventing mobility of free electron carriers therethrough to electrically isolate each one of the thick sub-structures from every other one of the thick sub-structures. Further, the plurality of microLEDs share the active region.

摘要： A light emitting diode (LED) structure includes a semiconductor template having a template top-surface, an active quantum well (QW) structure formed over the semiconductor template, and a p-type layer. The p-type layer has a bottom-surface that faces the active QW and the template top-surface. The bottom-surface includes a recess sidewall. The recess sidewall of the p-type layer is configured for promoting injection of holes into the active QW structure through a QW sidewall of the active QW structure.

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： The disclosure describes various aspects of an architecture for light emitting elements in a light field display. In an aspect, a light field display can include multiple picture elements (e.g., super-raxels), where each picture element includes multiple sub-picture elements monolithically integrated on a same semiconductor substrate. Each sub-picture element has a respective light steering optical element and includes an array of light emitting elements (e.g., sub-raxels) that produce the same color of light. The light steering optical element can include at least one microlens, at least one grating, or a combination of both. Separate groups of light emitting elements can be configured and a directional resolution of the light field display can be based on the number of groups. The light field display also includes electronic means configured to drive the light emitting elements in each sub-picture element.

摘要： A stereo viewing system includes a projector and an eyepiece. The projector includes a first microdisplay and emits first and second spatially-modulated light associated with a first image and second image, respectively. The eyepiece includes an eyepiece substrate, a first and second input coupling element, and a first and second output coupling element. The first input coupling element receives the first spatially-modulated light from the projector and incouples the first spatially-modulated light into the eyepiece substrate. The first output coupling element projects at least a portion of the incoupled spatially-modulated light out of the eyepiece substrate from a user-side surface of the eyepiece substrate. The second input coupling element incouples the second spatially-modulated light, received from the projector, into the eyepiece substrate. The second output coupling element projects at least a portion of the incoupled spatially-modulated light out of the eyepiece substrate from the user-side surface.

摘要： A display system includes (i) a plurality of picture elements supported on a single semiconductor substrate and (ii) a backplane including electronic circuitry supported thereon and electronically connected with the picture elements. Each picture element includes a light steering optical element and an array of light emitting elements. The array of light emitting elements includes a first set, a second set, and a third set of inorganic LEDs that (i) are monolithically integrated on the single semiconductor substrate and (ii) emit, respectively, light at a first, a second, and a third wavelength, which are mutually distinct. The light steering optical element is configured for steering the light from the first set, second set, and third set of LEDs in a predetermined direction. The electronic circuitry is configured for individually driving each light emitting element of the array of light emitting elements.

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.
