The following description is made by way of example with reference to a set of lens modules 10, an image generation module 20 and an adjustment assembly 30.

Specifically, the lens module 10 and the image generation module 20 are disposed opposite to each other and movably connected to each other, and it can be understood that the moving direction of the image generation module 20 faces toward or away from the lens module 10. Generally, the central axis of the image generation module 20 coincides with the optical axis of the lens module 10, and the image generated by the image generation module 20 is projected in a predetermined direction by the lens module 10, generally, the projection direction is the human eye direction. The adjusting assembly 30 is engaged with the image generating module 20, so that the adjusting assembly 30 can adjust a distance between the image generating module 20 and the lens module 20, specifically, the image generating module 20 is provided with a driving shaft 21, the adjusting assembly 30 is provided with a slide rail 31, the slide rail 31 is engaged with the driving shaft 21, the driving shaft 21 is sleeved in the slide rail 31 and can extend out of the slide rail, and the slide rail 31 defines a stroke of the driving shaft 21, that is, a stroke of the image generating module 20 and a stroke of the lens module 10 moving relative to each other. In operation, the driving shaft 21 is driven to move along the sliding rail by applying a driving force to the driving shaft 21, so as to drive the image generation module 20 to move. The slide rail 31 may be rectangular or other spline curve, and is not limited herein.

As such, the display device 100 and the electronic device 1000 according to the embodiment of the present invention allow a user to adjust diopter to be suitable for different users.

It can be understood that the involute curve is gradually changed from the center of the adjusting assembly 30 with respect to the circumference curve, and the adjusting assembly 30 can drive the driving shaft 31 to move the image generation module 20 along the optical axis direction of the lens assembly 10 by rotation. Moreover, the adjusting assembly 30 drives the image generating module 20 to move at a smaller horizontal distance with a larger rotating distance, thereby improving the adjusting precision.

In addition, the adjusting assembly 30 drives the image generation module 20 to move in a rotating manner, which effectively reduces the space required for adjustment, thereby reducing the size of the electronic device 1000 in the optical axis direction of the lens assembly 10.

In some embodiments, the lens module 10 includes a lens barrel and a lens assembly. The lens assembly includes one or more lenses. The lens barrel generally has an entrance port and an exit port, the entrance port faces one side of the image generation module 20, and light entering the entrance port passes through the lens assembly and is refracted and reflected, and finally exits from the exit port. Generally, the image generating device 20 includes a display, such as an LED display or an OLED display, and the display is disposed on the entrance port. Therefore, the light rays of the image displayed by the display enter the entrance port and are projected to the preset direction by the lens group, the light rays emitted from the exit port enter human eyes, and the human eyes can see the amplified virtual image of the image displayed by the display.

In some embodiments, the lens module 10 is provided with a pin 12, and the image generation module 20 is provided with a pin hole 22 that is matched with the pin 12.

The pins 12 and the pin holes 22 may be symmetrically disposed on both sides of the lens module 10 and the image generation module 20, respectively.

In operation, a driving force is applied to the adjusting assembly 30, the driving force acts on the driving shaft 21 of the image generation module 20, the driving shaft 21 drives the image generation module 20 to move horizontally along the optical axis direction of the lens module 10, and the moving stroke is limited by the sliding rail 31 of the adjusting assembly 30 or the sliding groove 41 of the fixing plate 40.

In some embodiments, the upper surface of the fixation plate 40 may be flush. In other examples, the fixing plate 40 may also be made into a step shape, wherein the thickness of the fixing plate 40 may be reduced from the side of the lens module 10 to the side of the image generating module 20 on the basis of ensuring the strength, and the side with the smaller thickness may be used to accommodate part of the adjusting assembly 30, so as to reduce the overall height of the side of the image generating module 20, and make the whole electronic device 1000 thinner and lighter.

In some embodiments, the adjusting assembly 30 includes a rotating member 32, and the rotating member 32 has a sliding rail 31. The fixed plate 40 is further provided with a through hole 42, the rotating member 32 includes a rotating shaft, and one end of the rotating shaft penetrates through the through hole 42.
