Embodiment Construction

[0014] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] When the triangular waveguide scheme is used as light output, Figure 1 is a realization of this scheme.

[0016] The coating characteristics of the W-shaped semi-reflective coating layer of the triangular waveguide in Figure 1 are determined to be completely transparent when the incident light angle is small, and semi-transparent and semi-reflective when the incident angle is large.

[0017] In Figure 1, 1 is the light transmitted in the waveguide. When the light encounters the first semi-reflecting surface, an output light 4 is generated. When the light encounters the second and third reflecting surfaces, the light passes through directly. When there are 4 reflective surfaces, an output light 2 is generated. When the 5th and 6th reflective surfaces are encountered, the light passes through directly. When the 7th reflective surface is e...

Abstract

The invention discloses a triangular waveguide scheme which can realize multiple functions on the same waveguide. Double-face output display can be achieved when the optical fiber is used for displayoutput, two-way transmission of light can be achieved when the optical fiber is used for image light input, and double-face light receiving can be achieved when the optical fiber is used for light receiving.

Description

technical field [0001] The invention relates to a planar waveguide solution, in particular to a triangular waveguide solution. Background technique [0002] When the existing waveguide solution is used for near-eye display, it can only output images on one side of the waveguide. When the existing waveguide solution inputs light, it can only receive light from one side, and can only transmit light in one direction. Contents of the invention [0003] The present invention provides a triangular waveguide solution aimed at planar waveguides, which can realize multiple functions on the same waveguide. When used as display output, it can realize double-sided output display, when used as image light input, it can realize two-way transmission of light, and when used as light receiving, it can realize double-sided light reception. [0004] The present invention is realized through the following technical solutions: [0005] A triangular waveguide scheme. The waveguide section is ...
