Problems solved by technology

[0002] At present, the existing head-mounted displays are large in size and heavy in weight, and compound-eye light-field head-mounted displays cannot see through. In terms of display and optical technology, only flat 3D display can be realized. Generally, the viewing angle is relatively small, so the small field of view imaging is unrealistic and the experience is not good. it is good

Abstract

The invention discloses a perspective head-wearing type light field display device. The device comprises a display screen arranged at the position, above the eyes of a person, on the forehead. A micro-lens array is arranged in front of the display screen, a semi-reflection and semi-transmission mirror is arranged in front of the micro-lens array and used for reflecting part of light of the micro-lens array and enabling environment light to transmit into the eyes of the person, the semi-reflection and semi-transparent mirror is disposed in front of the eyes of the person, and a processor connected with the display screen is further installed. The display device is simple in structure and convenient and quick to use, the volume structure and the weight can be effectively reduced, the visual angle can be widened, 3D images with a field depth stereoscopic effect are obtained, good adaptability is achieved, good practicality is achieved, and the structure is compact and reasonable.

Description

Technical field [0001] The invention belongs to the technical field of head-mounted equipment, and particularly relates to a see-through head-mounted light field display device. Background technique [0002] At present, the existing head-mounted displays are bulky and heavy, and compound-eye light-field head-mounted displays cannot see through. In terms of display and optical technology, only flat 3D displays can be realized. Generally, the viewing angle is relatively small, so the small field of view and the unreal experience of imaging are not it is good. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a see-through head-mounted light field display device with simple structure, convenient use and small volume. [0004] The technical solution for achieving the objective of the present invention is: a see-through head-mounted light field display device comprising a display screen arranged on the forehead above the eye...
