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 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.

In an aspect, a light field display can include multiple picture elements (e.g., super-raxels), where each of the picture elements has a respective light steering optical element and includes an array of light emitting elements (e.g., sub-raxels) that area monolithically integrated on a same semiconductor substrate. The light steering optical element can include at least one microlens, at least one grating, or a combination of both. The array of light emitting elements includes light emitting elements that produce at least three different colors of light. 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 individually drive the light emitting elements in each of the picture elements.
