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.
