Problems solved by technology

[0005] Our company applied for the patent No. CN201620380830.6 in 2016, which involves this field. However, during the implementation of this patent, there are shortcomings such as small eye movement range and excessive overall optical volume, which have caused serious damage to the layout of the AR glasses. Due to the impact, it is not suitable as an implementation of new AR glasses

Embodiment Construction

[0046] The second embodiment of the present invention will be briefly described below in conjunction with the accompanying drawings.

[0047] The projection lens 3 used in this embodiment is a lens group composed of a convex lens 31 and a concave lens 32 .

[0048] Such as figure 1 As shown, a kind of near-eye display video glasses with a multilayer microprism waveguide structure, including an OLDE or LCOS display 1 , a microstructure waveguide substrate 2 , a projection lens 3 and a longitudinal prism 5 . The end of the projection lens 3 away from the longitudinal prism 5 faces the display 1 , and the light beam emitted by the display 1 enters the human eye 4 through the projection lens 3 , the longitudinal prism 5 , and the microstructure waveguide substrate 2 in sequence.

[0049] A display 1 fixing device (not shown in the figure) for fixing the display 1 is also provided on one side of the display 1 .

[0050] Such as Figure 8 As shown, the projection lens 3 is used t...

Abstract

The invention aims to provide a pair of near-to-eye display video glasses with a multi-layer microprism waveguide structure. The pair of near-to-eye display video glasses comprises a displayer, a microstructure waveguide substrate, a projection lens and a longitudinal prism, wherein one end away from the longitudinal prism of the projection lens faces to the displayer; a light beam emitted by thedisplayer successively passes through the projection lens, the longitudinal prism and the microstructure waveguide substrate and enters the eyes; the projection lens is used for amplifying the light beam emitted by the displayer. Through applying the near-to-eye display video glasses with the multi-layer microprism waveguide structure, the eye movement range of augmented reality glasses carrying the structure is broadened; meanwhile, the whole optical structure is smaller and lighter, and is more conducive to enhancement of the quantity production and the popularization of intelligent glasses.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to near-eye display video glasses with a multilayer microprism waveguide structure. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. the real world and interact with it. This technique was proposed in 1990. With the improvement of the CPU computing power of portable electronic products, it is expected that the application of augmented reality will become more and more extensive. [0003] Augmented reality glasses (AR glasses) are an important means of expression of augmented reality technology. There are a variety of optical solutions in the prior art that can realize the display effect of augmented reality to varying degrees. [0004] The optical ...
