Abstract
Disclosed are a waveguide display module, and an image generation module and application corresponding thereto. By wavelength division multiplexing, an image generation unit generates through modulation mixed light beams containing at least two groups of sub-images of different wavelengths. The mixed light beams generated through modulation by the image generation unit are coupled into a waveguide module, which module has in-coupling units arranged in multiple layers and out-coupling units arranged in multiple layers, an in-coupling unit in each layer being configured to couple in light of different wavelength ranges. Emergent images, formed after mixed light beams of an image to be displayed generated by the image generation unit are coupled out by the out-coupling units of the waveguide module, are spliced into the image to be displayed.
