AR display glasses

Abstract

The invention relates to the technical field of display equipment, in particular to AR display glasses with optical diopter. The AR display glasses comprise a planar waveguide lens and a vision correction lens arranged on the inner side of the planar waveguide lens, the planar waveguide lens is provided with a coupling-in area and a coupling-out area, and the coupling-in area is used for receivingimage light entering from a certain incident angle, converting the image light into first diffracted light and transmitting the first diffracted light to the coupling-out area through the planar waveguide lens; the coupling-out area is used for receiving the first diffracted light and the entity light from the real object and transmitting the first diffracted light and the entity light to human eyes through the vision correction lens. The beneficial effects of the AR display glasses are that the AR display glasses can achieve the AR display and vision correction at the same time through the planar waveguide lens and the vision correction lens disposed at the inner side of the planar waveguide lens with no need to additionally wear glasses for vision correction so that the AR display glasses are simple and convenient, good in imaging effect and convenient to carry.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to an AR display glasses with optical diopter. Background technique [0002] Augmented Reality (AR for short) is a technology proposed in 1990 that "seamlessly" integrates real world information and virtual world information. etc.), through science and technology such as computers, virtual information is applied to the real world, and is perceived by human senses, so as to achieve a sensory experience beyond reality. It can combine real and virtual worlds to create a new visualization environment, and has broad application prospects in important fields such as military, medical, education, games and life. Most of the current mainstream near-eye augmented reality display devices use the principle of optical waveguide, which is mainly composed of microdisplay, grating and planar waveguide. [0003] Nowadays, a variety of electronic products occupy people's l...

AI Technical Summary

Problems solved by technology

Users with visual impairments cannot see real objects clearly through AR display glasses without diopter lenses

Also, non-diopter lenses may not be able to focus virtual information on the retinas of such users

Therefore, people with vision defects can only wear vision correction glasses and then wear AR display glasses, but the comfort is very poor

Therefore, this kind of lens cannot provide practical and comfortable AR display glasses for users with visual impairment
