light field display system

Abstract

The invention relates to a light field display system, comprising: a plurality of light field display modules spliced ​​at an angle, each light field display module comprises a display screen and a microlens array located on the light-emitting side of the display screen; a lens group includes The splicing lenses corresponding to the plurality of light field display modules one-to-one are used to form a plurality of first imaging surfaces corresponding to the plurality of light field display modules one-to-one on the side of the light field display module away from the splicing lens, And the plurality of first imaging surfaces are seamlessly spliced ​​to form a plurality of second imaging surfaces that are seamlessly spliced ​​on the side away from the plurality of light field display modules, wherein the first imaging surfaces What is displayed is the upright virtual image of the corresponding light field display module.

Description

technical field [0001] The present invention relates to the technical field of light field display, and in particular, to a light field display system. Background technique [0002] In recent years, with the development of 3D technology, VR display technology has received widespread attention, but its disadvantage is that there is a problem of vergence conflict (the stereo vision position of the binocular does not match the focus position of the monocular), and long-term viewing will cause dizziness. As a display solution that can solve the problem of human eye vergence conflict, light field display has been studied in academia for a long time, but it has not achieved satisfactory results in terms of imaging field of view and vision imaging clarity. For example, for an optical device that uses microlenses to realize light field display, due to the limitation of the aperture of the single lens and the limitation of the imaging field of view, the imaging field of view of the l...

Problems solved by technology

[0002] In recent years, with the development of 3D technology, VR display technology has received widespread attention, but its disadvantage is that there is a problem of convergence conflict (the binocular stereo vision position does not match the monocular focus position), and it will cause dizziness when watching for a long time

As a display solution that can solve the problem of human eye convergence conflict, light field display has been studied in academia for a long time, but it has not been able to achieve satisfactory results in terms of imaging field of view and distant imaging clarity.

For example, the optical device that uses microlenses to realize light field display, due to the limitation of the aperture of the single lens and the limitation of the imaging field of view, the light field imaging field of view is limited within ±10°, and with the increase of the imaging depth ( The distance from the light field image surface to the display screen), the imaging clarity gradually decreases

[0003] To solve the problem of imaging field of view, it is easy to think of a method of splicing display screens. However, due to the limitation of the frame of the display screen, a seam will be formed at the joint of two adjacent display screens after splicing, thus forming a black area of ​​a certain size on the imaging surface.
