Abstract

The invention discloses a waveguide display device, and relates to the technical field of optics. The device comprises an image source, a relay optical system, an input coupler, a waveguide, an output coupler and a controller, wherein the image source is used for displaying an image; the relay optical system is used for directing the image displayed by the image source to the input coupler; the input coupler is used for coupling outgoing lights of the relay optical system to the waveguide; the output coupler is used for coupling out the lights traveling in the waveguide, wherein the output coupler comprises a waveguide coupling optical grating, and the waveguide coupling optical grating comprises a plurality of monochrome optical gratings corresponding to lights of different wavelength. In the device, full color display can be realized in the case of a large field angle and a small-sized image source.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular to a waveguide display device. Background technique [0002] With the development of science and technology, augmented reality display devices have attracted more and more attention. In the prior art, a monochromatic waveguide display technology is commonly used. [0003] However, the color waveguide display technology can provide a more complete information display and can greatly improve the user experience, which cannot be provided by the existing technology. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a waveguide display device. The purpose is to solve the problem that color display cannot be performed in an augmented reality display device. In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended to be an extensive review, nor is it inten...
