Abstract
The present disclosure generally relates to light field displays and methods of displaying images with light field arrays. In one example, the present disclosure relates to pixel arrangements for use in light field displays. Each pixel includes a plurality of LEDs, such as micro LEDs, positioned adjacent respective micro-lenses of each pixel.
Claims19
A light field display, comprising:
- a plurality of micro-lens groups, wherein
- each micro-lens group comprises a plurality of micro-lenses,
- each micro-lens has a corresponding micro-LED device array positioned therebeneath, the micro-LED device array comprising a plurality of micro-LED devices, and
- each micro-LED device in the micro-LED device array comprises a reflective surface formed to collimate light emitted by an active stack of the micro-LED device and to direct the collimated light towards a micro-lens positioned thereabove.

A light-field display, comprising:
- a plurality of pixels of spatial resolution, each pixel of spatial resolution comprising:
- a plurality micro-LED arrays, each micro-LED array comprising a monochromatic plurality of micro-LED devices;
- and
- a plurality of micro-lens respectively positioned above each micro-LED array, wherein each of the micro-LED devices in a micro-LED array is configured to direct collimated light towards a corresponding micro-lens, and wherein the corresponding micro-lens changes the directions of the collimated light from a plurality of the micro-LED devices to provide a corresponding plurality of pixels of angular resolution.
1 more element
A light-field display, comprising:
- a plurality of pixels of spatial resolution, each pixel of spatial resolution comprising:
- one or more light-directing features formed on a substrate panel;
- and
- a corresponding micro-LED device positioned beneath each of the one or more light-directing features, the corresponding micro-LED device comprising an active stack and a reflective layer used to collimate light emitted by the active stack and to direct the collimated light towards the corresponding light directing feature.
