Problems solved by technology

[0003] At present, most of the optical solutions in near-eye display devices based on augmented reality technology use the polarization array optical waveguide solution. Polarized light waves (polarization vectors are in this plane) couple light out, and the light efficiency of the waveguide lens is very low, so that the final eye-catching brightness is greatly reduced, which cannot meet the eye-catching brightness requirements for some specific workplaces.
On the other hand, it is precisely because of the design requirements of the polarization beam-splitting film array waveguide lens that most of the optical-mechanical collimation systems in near-eye display devices based on augmented reality technology use the polarization beam-splitting prism (PBS) scheme, which makes the optical-mechanical weight and cost higher

Abstract

The invention relates to a near-to-eye display device for augmented reality and augmented reality display equipment. The near-to-eye display device comprises a display source, a collimation system and an unpolarized waveguide lens; the display source is arranged on a main optical axis of the collimation system and is used for loading and outputting an image; the collimation system is located on the light emitting surface of the display source and used for collimating and correcting the image output by the display source and then enabling the image to enter the unpolarized waveguide lens, the collimation system comprises a first lens, a second lens, a third lens and a fourth lens which are coaxially arranged in sequence from an object plane to an image plane, the first lens is a plano-convex lens, the second lens is a plano-concave lens, the third lens is a plano-convex lens, and the fourth lens is a plano-convex lens; and the unpolarized waveguide lens is arranged on the emergent light path of the collimation system and is used for coupling the coupled light to human eyes. According to the technical scheme, the lighting effect of the waveguide lens is improved, and the final in-eye brightness is improved.

Description

technical field [0001] The present disclosure relates to the field of augmented reality display technology, and in particular, to a near-eye display device and augmented reality display device for augmented reality. Background technique [0002] Augmented reality technology is a technology that projects virtual images to the human eye while allowing users to view the surrounding environment. Due to the unique feature of this technology that can superimpose the projected image on the real world perceived by the user, it is used in Virtual reality and augmented reality fields such as military, industrial design and manufacturing, medical treatment and entertainment have been widely used. [0003] At present, most of the optical solutions in near-eye display devices based on augmented reality technology use the polarization array optical waveguide solution. Polarized light waves (polarization vectors are in this plane) are coupled out, and the light efficiency of the waveguide...
