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 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.
