In an embodiment, the display device further includes a tightening member, such as a threaded column or an arc-shaped elastic sheet (not shown), where the arc-shaped elastic sheet is disposed in the mounting groove 13 and abuts against the sleeve 30, or the threaded column abuts against a side wall of the sleeve 30 by penetrating the mounting groove 13, and the tightening member can enable the assembly of the spherical mounting groove 13 and the spherical sleeve 30 to be more tightly matched, so as to reduce the probability of random shaking of the sleeve 30.

In some embodiments, referring to fig. 7-10, the second mount 12 is configured to abut the outer lens 2 and/or the housing 3, and the end surface of the micro-display 20 is lower than the end surface of the second mount 12, such that the risk of rubbing the micro-display 20 may be reduced, thereby creating a protection. The display device further includes a second protective layer 52, where the second protective layer 52 is located on a surface of the second mount 12.

In some embodiments, referring to fig. 7-10, the display device 1 further comprises a second connecting member 40, the second connecting member 40 being spaced apart from the first mounting seat 11, or the second connecting member 40 being spaced apart from the second mounting seat 12, the second connecting member 40 being configured to allow clamping of the external lens 2 and/or the housing 3 with the first mounting seat 11 or the second mounting seat 12, a side of the second connecting member 40 facing the first mounting seat 11 or the second mounting seat 12 being provided with a third protective layer 53.

In practical applications, since the lens 2 is mostly made of precise devices, such as resin or glass, and the contact friction between the first mount 11, the second mount 12 and the second connector 40 and the lens 2 easily causes abrasion of the lens 2, the protective layer can play a role in buffering and protecting, so that the lens 2 is prevented from being directly worn by the hard rigid material, the first protective layer 51, the second protective layer 52 and the third protective layer 53 can be made of soft materials, such as pvc (polyvinyl chloride), sponge, rubber, plastic, etc., and the first protective layer 51 and the second protective layer 52 can be made of thin materials, such as a plated film or a coated layer, etc., which are arranged at the connecting portion corresponding to the contact surface of the lens 2, so long as the protective layer can be contacted with the lens 2 and is not easy to damage the lens 2 in the moving process, thereby realizing a certain protection. It is of course also possible to provide a protective layer on both sides of each of the first mounting 11 or the second mounting 12, ensuring the whole integrity.

The second connector 40 and the second mount 12 are configured to clamp the lens 2 to each other and allow the mount 10 to move over the lens 2 to adjust the position of the micro-display 20 relative to the lens 2. Or the second connection 40 and the first mounting seat 11 are configured to grip the lens 2 with each other and allow the mount 10 to move on the lens 2 to adjust the position of the micro-display 20 relative to the lens 2, it being understood that, for example, in a case where the lens 2 has at least one first position and a second position different from the first position, it is free to move between the first position and the second position; the specific movement may be a position movement with respect to the periphery of the lens by a certain distance, or any position movement with respect to the lens 2. As long as the adjustment movement of the light exit position of the adjustable micro-display 20 with respect to the visual range of the human eye is satisfied.

By adjusting the position of the microdisplay 20 relative to the field of view of the human eye, the position of the microdisplay can be accurately adjusted to achieve the visual perception of the human eye, thereby meeting different people with different interpupillary distances or viewing fields and meeting different user viewing requirements and preferences. On the other hand, flexible position test can be provided in the early development, and the expected design effect is realized.

In some embodiments, the second connecting member 40, the first mount 11, and the second mount 12 may be magnetic materials that attract each other, the second connecting member 40 and the first mount 11 may be magnets, or the first mount 11, the second mount 12 may be a metal such as iron, cobalt, nickel, and alloys thereof, and the second connecting member 40 may be a magnet, although the order of the two may be reversed. So long as the clip-like effect can be achieved.

In some embodiments, referring to fig. 2-3 in combination, the first mount 11 and the second mount 12 may be integrally formed.

In some embodiments, the display device 1 may further include a connector (not shown) having one end connected to the first mount 11 and/or the first protective layer 51 and the other end connected to the second connector 40 and/or the third protective layer 53, or having one end connected to the second mount 12 and/or the second protective layer 51 and the other end connected to the second connector 40 and/or the third protective layer 53; the connection members are arranged across the lens 2, for example the connection members may be U-shaped. It will be appreciated that the two ends of the connecting member may be directly connected (e.g. glued, etc.) to the first mounting seat 11 and the second mounting seat 12; since the protective layer is directly connected to the connection portion, the connection member may also be connected to the first protective layer or the second protective layer 52, and optionally, the connection member may also wrap around the first mount 11 or the second mount 12. The arrangement of the connecting piece can reduce the probability of losing the component, and it can be understood that the display module is smaller than human eyes, and the maximum diameter of a single first or second connecting part can be 5 mm or less; thus, the first fitting seat 11 and the second fitting seat 12 are connected together, so that the first fitting seat and the second fitting seat can be connected with the lens 2 or the frame as a whole, and the whole is relatively large when the first fitting seat and the second fitting seat fall down, so that the first fitting seat and the second fitting seat are easy to find or pick up. Alternatively, referring to fig. 7, the connection member may be integrally formed with the protective layer, and the same material may be used, for example, the first protective layer 51, the second protective layer 52, the third protective layer 53, the connection member, and the like may be integrally formed, so that the connection member may perform both the connection and protection functions.

In other embodiments the connection may be replaced, for example to accommodate a position shift of a different lens 2, alternatively the connection may also be provided in a telescopic or elastic arrangement, i.e. with an adjustable overall length.

Alternatively, referring to fig. 3 to 5, a recess 113 is formed in a side of the first mount 11 facing away from the micro display 20, and the iron sheet 50 or the magnet 50, etc. may be disposed in the recess 113, and then the first protective layer 51 may be disposed on the first mount 11, for example, by using an adhesive or the like.

In some embodiments, the maximum diameter of the first mount 11 and/or the second mount 12 may be less than or equal to 5mm, and the small size may enable a lightweight fit, which is not prone to have excessive impact on the applied optical lens.

In some embodiments, as in fig. 1-5, the first mount 11, the second mount 12 face away from the light-emitting side of the microdisplay 20. Such a design ensures that the microdisplay 20 is directed toward the human eye, as shown in fig. 1, the entire mount 10 may be positioned on the side of the lens 2 facing the human eye, i.e., the light of the microdisplay 20 may enter the human eye without passing through the lens 2, i.e., the built-in assembly of the microdisplay 20 may allow the light of the microdisplay 20 to enter the human eye directly without considering the light effects of the lens 2, such as loss of light from the microdisplay, etc.

In other embodiments, referring to fig. 1-5, the first assembly seat 11, the second assembly seat 12 and the sleeve 30 are coaxially disposed, the wire hole 111 can leak out from the side wall of the base 11, the axial direction of the wire hole 111 is perpendicular to the connection line direction between the first assembly seat 11 and the second assembly seat 12, and the wire groove of the wire hole 111 is hidden inside the base 11 by being shielded by the first assembly seat 11. Wherein, the first through hole 31 can be located at the bottom of the center of the sleeve 30, and can be coaxially arranged with the base 11, so that the whole appearance is more attractive due to the hidden wiring, and the angle adjustment of the ball sleeve 30 can not be affected due to the coaxial arrangement.

In some embodiments, referring to fig. 6 to 10 in combination, the mounting base 10 may include a first mounting base 11 and a second mounting base 12 disposed on the first mounting base 11, where the first mounting base 11 and the second mounting base 12 may be disposed in parallel, for example, the first mounting base 11 and the second mounting base 12 may be fixed by using an adhesive or magnetic attraction manner, where in some embodiments, the first mounting base 11 and the second mounting base 12 may be convenient to mount and dismount the mounting base, which is beneficial to mounting and replacing the micro display 20, and may make full use of magnetism of the first mounting base 11 and the second mounting base 12 to further couple to the magnetic attraction manner of the first mounting base 11 and the second mounting base 12, so that the whole device assembly is more flexible.

With continued reference to fig. 6-10, it will be appreciated that a locating hole 114 and a locating post may be provided between the first mounting seat 11 and the second mounting seat 12, and the locating post and the locating hole may perform a foolproof locating function, although in some implementations, the locating may also be a part of the first mounting seat 11; the first assembly seat 11 is provided with a wire outlet hole 111, the first assembly seat 11 and the second assembly seat 12 are coaxially provided with a mounting groove 13, the mounting groove 13 is a spherical mounting groove, the sleeve 30 is a spherical sleeve, the spherical sleeve 30 can be configured to rotate in the spherical mounting groove to adjust the light emitting direction of the micro display 20, and when the light emitting angle of the micro display 20 needs to be adjusted, the rotating direction of the spherical sleeve 30 can be operated, for example, the rotation direction of a finger or a special tool can be adjusted, wherein the second assembly seat 12 faces the light emitting side of the micro display 20. The wire outlet hole 111 may be located at a side of the first mount 111 facing away from the micro display 20.

In some embodiments, with continued reference to fig. 8-10, the second connector 40, the second protective layer 52, and the third protective layer 53 are provided with light exit holes 54. The size of the light exit aperture 54 may be larger than the size of the micro display 20. The light exit hole 54 ensures that the light of the micro-display 20 can reach the eyes of a person, it can be appreciated that the entire mounting base 10 can be located on one side of the lens 2 away from the eyes, and the first mounting base 11 and the second mounting base 12 can be spaced on two sides of the light exit hole 54, that is, the light of the micro-display 20 passes through the lens 2 before entering the eyes, that is, the external mounting mode of the micro-display 20, and such a mode (the internal mounting mode of the micro-display 20) can reduce discomfort, such as psychological discomfort, caused by the fact that the whole mounting base 10 protrudes relative to the lens 2 and faces the eyes directly.
