Description

Augmented reality glasses and method for displaying image using the same Technical Field The present disclosure relates to the field of augmented reality technology, and in particular, to augmented reality glasses and a method of displaying images using the same. Background Augmented reality (Augmented Reality, AR) glasses superimpose computer-generated virtual information (e.g., images, text, 3D models) into the real world field of view seen by the user through lens or projection techniques, which may provide a richer visual experience. In the related art, AR glasses include a micro-display module for emitting image light, and a waveguide for guiding the image light into human eyes. However, most of the lens structures adopting the waveguide scheme are generally thicker, and there is a large energy loss in the process of transmitting and coupling out light in the waveguide, so that the overall light efficiency is low, and the visual experience is affected.
