Abstract
The present disclosure discloses AR glasses including an image projection device, an optical lens, a beam splitter, a first ¼λ wave plate, a curved half-mirror, and a liquid crystal dimming film. The liquid crystal dimming film includes a polarizer and a dye-doped liquid crystal layer. The light transmittance of the dye-doped liquid crystal layer is adjusted by an applied voltage. When the liquid crystal layer absorbs light, it can effectively block external stray light, and also prevent viewing displayed image from being viewed from an outside world to achieve privacy protection. This greatly improves the contrast of the virtual image and enhance the immersion.
