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.
