In this embodiment, the first optical structure 120 and the second optical structure 130 are independent of each other (i.e. the adjustment of the first optical structure 120 does not affect the second optical structure 130, and the adjustment of the second optical structure 130 does not affect the first optical structure 120), so that the pupil distance of the AR display device 100 can be adjusted by changing the position of the first optical structure 120, and the pupil distance of the AR display device 100 can also be adjusted by changing the position of the second optical structure 130, so that the positions of the first optical structure 120 and the second optical structure 130 can correspond to the pupil positions of the two eyes of the user. Accordingly, the AR display device 100 may be well suited for different users. And such a configuration may make adjustment of the AR display device 100 (i.e., adjustment of the relative distance between the first optical structure 120 and the second optical structure 130 to adapt the AR display device 100 to the pupillary distance of the user) simple and efficient.

The first interpupillary distance adjusting device 140 and the second interpupillary distance adjusting device 150 are not limited to the above-described configuration, and may have other types of configurations, and the first interpupillary distance adjusting device 140 and the second interpupillary distance adjusting device 150 may have different configurations (or may have different adjustment methods).

Such a configuration may make adjustment of the AR display device 100 (adjustment of the relative distance between the first optical structure 120 and the second optical structure 130 to adapt the AR display device 100 to the pupillary distance of the user) simple and efficient.

For example, the first adjustment member 141 may be an adjustment lever, and the first transmission member may be a guide rod.

Such a manner may protect the guide rod and define the movement direction of the adjustment rod, thereby ensuring the accuracy of the guide rod to the movement transmission, and facilitate the user's interpupillary distance adjustment of the AR display device 100.

The above is the description of the first interpupillary distance adjusting device 140, and the second interpupillary distance adjusting device 150 may adopt the same structure and principle as the first interpupillary distance adjusting device 140, and will not be described herein again.

Therefore, the present application should not be considered as limited herein.

In order to enable the AR display device 100 to be suitable for users with different eyesight, in the present embodiment, the AR display device 100 may further include a first diopter adjusting means 171 and a second diopter adjusting means 172.
