wherein the circuit board 30 and the battery 40 each correspond to a position on the waveguide sheet 10 except for the coupling-in region 11 and the coupling-out region 12.
It should be noted that, in the present application, the optical device 20, the circuit board 30 and the battery 40 are all disposed on the waveguide sheet 10, instead of disposing the optical device 20, the circuit board 30 and the battery 40 on the glasses legs in the prior art, the AR lens of the present application is beneficial to reducing the volume of the glasses legs, and is convenient to wear.
The AR lenses are worn in at least two ways: one is to arrange a frame for the AR lens to form AR glasses for wearing. Another is that the AR lens may be disposed on the ordinary eyeglasses (such a configuration may be a detachable configuration), and since the AR lens does not obstruct the use of the ordinary eyeglasses, the image display of the AR lens is realized on the basis of the ordinary eyeglasses and is emitted to the eyes of the user. The general glasses refer to articles for improving eyesight, protecting eyes or decorating purposes, and include lenses and a frame 1.
It should be emphasized that, in the first wearing manner, since the optical engine 20, the circuit board 30, the battery 40 and other components are disposed on the AR lens, the volume of the frame 1 can be greatly reduced, so that the frame 1 in the whole AR glasses is close to that of common glasses, and is more convenient to wear. In the second wearing mode, the AR lens is worn without the frame 1, but with the use of ordinary eyeglasses, and convenience in wearing the AR lens is ensured by the convenience in wearing ordinary eyeglasses.
