Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0034] In some application scenarios, different users have different interpupillary distances, and fixed content presentation often cannot meet the viewing needs of different users. Since different interpupillary distance users need to clearly view the display content, the development of multiple different models of products brings challenges such as manufacturing cost.

[0035] The present application provides a near-eye display module, a device and a wire. The following are described in detail.

[0036] Please refer to Figure 1 , Figure 1Figure 1 is a structural schematic diagram of an embodiment of a near-eye display module of the present application. The near-eye display module 1 provided by the present application comprises a near-eye display assembly 10, a wire 20, and an electrical assembly 30, wherein the near-eye display assembly 10 is configured to form an image source; the wire 20 comprises a first end 21 and a second end 22 opposite the first end 21, and the first end 21 is electrically connected to the near-eye display assembly 10; the electrical assembly 30 is electrically connected to the second end 22 of the wire 20 and electrically connects the near-eye display assembly 10 and the electrical assembly 30, and the electrical assembly 30 can be a battery, a camera, or other environmental detection sensors, etc. The electrical connection of the present application means that it can be electrically conducted after being powered on. The wire 20 is flexible, which can also be understood as elastic, flexible, etc. The wire 20 can be wrapped with a flexible or flexible or elastic outer layer to wrap a plurality of side-by-side conductive metal cores. The wire 20 is periodically bent and allows the near-eye display assembly 10 and the electrical assembly 30 to be elastically connected. In some embodiments, the periodic bending can be, for example, a wave shape or a sine wave shape or other regular bending shape. The wire 20 can be stretched, folded, or doubled, etc. under the external force of the user, that is, the electrical connection inside the wire 20 is not affected in the above various states. The near-eye display assembly 10 and the electrical assembly 30 are elastically connected at both ends of the flexible wire 20. The elastic connection can be understood as being stretched under the action of external force, and the wire 20 will return to the connection state before being stretched after the external force is removed. The distance between the near-eye display assembly 10 and the electrical assembly 30 can be flexibly stretched without affecting the electrical connection.

[0037] The wire 20 is configured to allow bending to locate the near-eye display assembly 10 on the first side A, and the electrical assembly 30 on the second side B facing away from the first side A. The bending can also be understood as folding, doubling, folding, etc. The same or similar, the first side A can be the near-eye side, that is, the side of the wearer's or user's eyes; the second side B can be the environment side or the world side, that is, the environment side facing away from the eye side. It can be understood that, referring to Figure 2, the user can actively bend the wire 20 into at least two parts across the two sides of the lens 100 and / or frame 110 when needed, so that the near-eye display assembly 10 is located on the first side A towards the human eye, while the electrical assembly 30 is located on the second side B away from the human eye, thereby flexibly clamping it on the lens 100 and / or frame 110. Since the near-eye display assembly 10, the wire 20 and the electrical assembly 30 are electrically connected with each other, the display of the image source can be realized, so that the traditional glasses such as myopia, hypermetropia, sports, sun or protective glasses can be effectively and compatibly adapted, and the ordinary traditional glasses can be changed into a smart glasses device with near-eye display. On the other hand, the flexibility of the wire 10 allows the length distance of the near-eye display assembly 10 and the electrical assembly 30 to be flexibly adjusted according to the needs, so that the length distance can be flexibly adjusted at multiple or any positions while maintaining the electrical connection, thereby adapting to the viewing needs of different field angles of different interpupillary distance users, and meeting the viewing needs and preferences of different users. In addition, the near-eye display module provided by the present application can be placed on the lens 100 and / or frame 110 when needed, and can be actively removed when not needed, thereby effectively improving the mobility and portability of the near-eye display module 1. Compared with the original fixed position content presentation, the near-eye display module of the present application provides higher compatibility, mobility and flexibility, without the need for additional development of multiple different models of products, thereby effectively reducing the manufacturing cost.

[0038] In some embodiments, in combination with reference to Figures 9-11The near-eye display assembly 10 comprises a first housing 11, a micro display 12, and an optical member 13. The first housing 11 is provided with a receiving cavity, and the optical member 13 is located on the light exit side of the micro display 12 and is located in the receiving cavity. In some embodiments, the first housing 11 can be further provided with a first clamping part such as a thread, a notch, or a fixing hole, and the optical member 13 can be provided with a second clamping part such as a thread, a notch, or a fixing column, which are matched with each other to fix the optical member 13. Of course, the optical member 13 can also be fixed by means of glue bonding. In some embodiments, the micro display 12 can also be fixed in the first housing 11 by means of clamping or bonding. The micro display 12 can be, for example, a Micro-LED (Micro Light-Emitting Diode), a uLED (micro light-emitting diode), a Micro-oled (Micro Organic Light-Emitting Diode), an LCoS (Liquid Crystal On Silicon), an LCD (Liquid Crystal Display), a DMD (Digital Micromirror Device) / DLP (Digital Light Processing), or an LBS (Laser Beam Scanning), or any combination of these technologies. The optical member 13 can be formed by injection molding, mold pressing, or turning, and can be made of resin or glass, which can include multiple reflection internal structures, for example, the optical member 13 can include two aspheric curved surfaces, and the two curved surfaces are provided with an entrance window, a first reflection surface, a second reflection surface, and an exit window. The light of the micro display 12 can enter through the entrance window, pass through the first reflection surface and the second reflection surface, and then exit through the exit window, so as to realize human eye retina imaging on the human eye side. In some embodiments, the description of the optical member 13 can also refer to the prior application technical solution of the application number 2023224964840, and the prior application technical solution of the application number 2024103064600 can also be used. As a person skilled in the art can set the above-mentioned or similar optical member 13 in front of the micro display 12 to realize image source projection to the human eye side, which will not be described here.

[0039] Continuing to refer to Figure 1 , 9-11, the electrical component 30 comprises a second housing 31, a circuit board 32, and a battery 33, wherein the battery 33 and the circuit board 32 are electrically connected, in some embodiments, the battery can be a rechargeable battery, for example, the second housing 31 can also be provided with a charging interface (not shown in the figure), such as a USB charging interface, a metal contact charging interface, or a wireless charging interface, etc., so as to facilitate charging of the battery 33. In some embodiments, the battery 33 can also be a replaceable battery. The battery 33 is electrically connected to the micro display 12 through the wire 20, thereby achieving power supply to the micro display 12 on the second side B away from the first side A, which can effectively reduce the thickness and volume of the first housing 11 caused by the battery 33 located on the same side of the micro display 12, and cause discomfort to the human eye. In addition, the battery 33 and the micro display 12 are changed to be movable through the elastic and bendable wire 20, so that the position adjustment of the near-eye display module 1 is more flexible.

[0040] In some embodiments, continue as Figure 1 、 4 , 9-11, the first housing 11 can be provided with a first magnetic member 14, and the second housing 31 can be provided with a second magnetic member 34, the first magnetic member 14 and the second magnetic member 34 are magnetically attracted to each other to respectively attract the near-eye display assembly 10 and the electrical component 30 to the first side and the second side, in combination with reference to Figure 2 、 4When the module 1 is placed on the lens 100 and / or the frame 110, the second magnetic attraction member 34 and the first magnetic attraction member 14 can magnetically attract each other to respectively clamp and fix the near-eye display assembly 10 and the electrical assembly 30 on different sides of the lens 100 and / or the frame 110. It can be understood that at least one of the first magnetic attraction member 14 and the second magnetic attraction member 34 can be a magnet, for example, both are magnets with opposite magnetic attraction; or one is a magnet and the other is a piece of iron or the like; in some embodiments, the first magnetic attraction member 14 can be a part of the first shell 11 as a whole, and the second magnetic attraction member 34 can be a part of the second shell 31 as a whole, in this case, the first shell 11 and the second shell 31 can be made of a metal material that is magnetically attracted, at this time, only a magnet needs to be arranged in one of the shells; in other embodiments, only a magnet can be arranged in the first shell 11, and the second shell 31 can not be provided with a magnet, and the battery 33 of the second shell 31 can be understood as the second magnetic attraction member 34 and be magnetically attracted. In some embodiments, the first magnetic attraction member 14 is located on the side of the first shell 11 away from the optical member 13, and the second magnetic attraction member 34 is located on the side of the second shell 31 away from the battery 33, which effectively improves the stability of magnetic fixation. In some embodiments, the magnetic attraction force between the first magnetic attraction member 14 and the second magnetic attraction member 34 is greater than the elastic restoring force of the elastic connection between the near-eye display assembly 10 and the electrical assembly 30, that is, the elastic restoring force of the wire 20 is less than the magnetic attraction force, so that when the near-eye display assembly 10 and the electrical assembly 30 are adjusted to the appropriate position, they can still be kept in the position by the magnetic attraction force, realizing the expected viewing angle. In other embodiments, the above-mentioned magnetic attraction method can also be replaced by a suction cup structure to achieve clamping and fixing between the near-eye display assembly 10 and the electrical assembly 30.

[0041] In some embodiments, a shielding layer can be further arranged between the second magnetic attraction member 34 and the circuit board 32 to reduce the electromagnetic interference of the magnet on the circuit board 32 or the battery 33.

[0042] In some embodiments, the second shell 31 can further be provided with an optical sensor or an image acquisition unit, the optical sensor can acquire external ambient light such as brightness information, and the image acquisition unit can be a camera for collecting external environmental content. The optical sensor or the image acquisition unit can be electrically connected with the battery 33, that is, the display module 1 is directed towards the human eye side A', and the camera is directed towards the environment side B', thereby facilitating the user to perceive the external environmental information when viewing the content from the micro display, for example, the content can be photographed by the image acquisition unit and viewed or real-time watched by the near-eye display assembly 10.

[0043] In some embodiments, the first housing 11 and / or the second housing 31 can further comprise a processor, a memory, a wireless communication unit, and other devices for data processing, transmission and communication, which can be electrically connected with the battery and the micro display 12, the wireless communication unit can be connected with an external terminal such as a mobile phone or a server, the memory stores one or more programs executed by the one or more processors, the one or more programs comprise a set of instructions for operation, and the digital image source is presented on the micro display 12.

[0044] In some embodiments, referring to Figure 5 and 8 , the bending shape of the wire 20 at least satisfies that the wire 20 first extends in a first direction, then bends away from the first direction to a second direction completely opposite to the first direction, continues to extend in the second direction, and then continues to bend away from the second direction to return to the first direction to continue to extend in the first direction. Wherein the first direction and the second direction can be two completely opposite directions on the same axis, for example, the first direction and the second direction can be as shown in Figure 5 the example of the bidirectional arrow line W, and the directions of the first end 21 and the second end 22 can be the example of the bidirectional arrow line L; for example, Figure 5 starting from the first end 21, the wire 20 can have a part extending along the bidirectional arrow line L, which can be electrically connected with the micro display 12 of the near-eye display assembly 10, and in some embodiments, this part can also not be required, referring to Figure 5 , the wire 20 then extends in the first direction, i.e. the left arrow of the bidirectional arrow line W, then bends away from the direction of the left arrow of the bidirectional arrow line W to extend in the direction of the right arrow of the bidirectional arrow line W (i.e. completely opposite to the first direction), and then continues to bend away from the right arrow of the bidirectional arrow line W to return to the left arrow of the bidirectional arrow line W to continue to extend in the direction of the left arrow, periodically bending from the first end 21 to the second end 22, and in the case of ignoring the thickness of the wire 20 itself, the wire 20 can be laid flat (or bent and stretched) after bending to form a plane, which is different from the spiral wire of the prior art which causes a larger space size, and the wire bending of the present application can reduce the space size, making the whole easier to store, and having a smaller visual effect.

[0045] In some embodiments, referring to 1-8, the shape of the wire 20 can comprise a plurality of units 28 in the direction from the first end 21 to the second end 22, for example Figure 5The middle line L shows that the unit 28 can be arranged periodically, and the specific number can be designed according to the length of the wire. The unit 28 can include two main body segments 29 connected to each other and a bending segment 26 connecting adjacent two main body segments 29. The adjacent two main body segments 29 extend in the same or parallel direction. The bending segment 26 can be in a U shape or an arc shape. The adjacent two main body segments 29 have a gap 201, and the bending segment 26 is arranged in an arc shape and elastically connects the adjacent two main body segments 29. The gap 201 can effectively improve the elastic stretching of the wire as a whole. When the first end 21 and the second end 22 of the wire 20 are stretched by external force, the main body segment 29 and the bending segment 26 will deform, thereby causing the gap 201 to further expand, thereby allowing the wire 20 to be lengthened, thereby effectively adjusting the distance between the near-eye display assembly 10 and the electrical assembly 30. When the external force is removed, the mutual magnetic attraction between the near-eye display assembly 10 and the electrical assembly 30 can overcome the elastic recovery and remain in the adjusted position.

[0046] In some embodiments, referring to Figures 1-11 , the bending segment 26 is configured to allow folding and forming the wire 20 into a first wire part 23, a second wire part 24, and a third wire part 25 connecting the first wire part 23 and the second wire part 24. The first wire part 23 is arranged at one end of the first side A and electrically connected to the near-eye display assembly 10. The second wire part 24 is arranged at the second side B, and one end is electrically connected to the electrical assembly 30. The third wire part 25 is arranged at the third side C, and the third side C connects the first side A and the second side B. Figure 3 The line H can be understood as the direction of the third side C, and can also be the height direction. It can be understood that the first wire part 23, the second wire part 24, and the third wire part 25 can be composed of one or more units 28 described above. The length relationship in the figure 3 is only an example position relationship, which can be stretched according to needs. The length of the third wire part 25 can be smaller than that of the first wire part 23 and the second wire part 24, respectively. The third wire part 25 can be formed by folding one of the bending segments 26. The third wire part 25 includes one unit 28. In other embodiments, the third wire part 25 can also include multiple units, depending on the thickness of the lens 100 or the frame 110 that the third wire part 25 needs to span. Thus, folding (or bending) at least one bending segment 26 realizes the folding of the wire 20, and the main body segment 29 is not folded, thereby effectively reducing the probability of damage to the wire during bending. In some embodiments, the lengths of the first wire part 23 and the second wire part 24 can be the same, thereby allowing the near-eye display assembly 10 and the electrical assembly 30 to be more accurately positioned.

[0047] The wire 20 is divided into the first wire portion 23, the second wire portion 24 and the third wire portion 25 for the purpose of clear description of the wire 20 on each side. In fact, the wires of the first wire portion 23, the second wire portion 24 and the third wire portion 25 can be arranged in a periodic coiled manner, and the bending sections 26 are named at the bending positions. The width of the bending section 26 is the distance between two adjacent main sections 29 extending in parallel. Figures 3-4 In some examples, the elastic connecting sections 27 and the bending sections 26 of the third wire portion 25 play a certain fixed supporting role when being folded, for example, supporting and fixing on the edge of the frame 110 or the lens 100.

[0048] In some examples, the length of the main section 29 is the same from the first end 21 to the second end 22, and the arc of the bending section 26 is the same. Figure 5 The wire 20 is also configured to allow unfolding to place the first end 21 and the second end 22 on the same side, so that the wire 20 can be unfolded and placed to facilitate picking up. In the non-stretched state of the wire 20, the gaps 201 between each two adjacent main sections 29 are consistent; in the stretched state of the wire 20, the gaps 201 between each two adjacent main sections 29 are at least partially different. For example, when being stretched, the main sections 29 near the first end 21 and / or the second end 22 of the wire 20 preferentially deform, and the corresponding gap 201 distance is larger than that of the gap 201 not being stretched in the middle. The gap 201 at the position not being stretched can remain unchanged. When the stretching force continues to increase, the gaps 201 of all the gaps can be expanded. When the stretching force is removed, the gap 201 distance will return to the initial state. The gap 201 effectively improves the elastic stretching and recovery of the wire 20, and in combination with the clamping and fixing (magnetic attraction) between the near-eye display assembly 10 and the electrical assembly 30, facilitates the user to manually move and adjust the distance between the near-eye display assembly 10 and the electrical assembly 30.

[0049] In some examples, as shown, the length of the main section 29 is the same from the first end 21 to the second end 22, and the arc of the bending section 26 is the same. Figure 5 In some examples, as shown, the length of the main section 29 is the same from the first end 21 to the second end 22, and the arc of the bending section 26 is the same.

[0050] In some examples, as shown, the length of the main section 29 is the same from the first end 21 to the second end 22, and the arc of the bending section 26 is the same. In some examples, the length of the main section 29 is the same from the first end 21 to the second end 22, and the arc of the bending section 26 is the same. This case can be seen in the non-stretched state, and of course the main section 29 and the bending section 26 can jointly deform after being stretched. Keeping the same length and arc can ensure that the overall wire 20 is more firm and the stress is more uniform, and it is also convenient for production and manufacturing.

[0051] In some embodiments, referring to Figures 5-8 , the wire 20 further comprises elastic connection sections 27, which are arranged between two adjacent main body sections 29, and have a length smaller than the main body sections 29 and a thickness smaller than the main body sections 29 and the bending sections 26. The materials of the elastic connection sections 27, the main body sections 29 and the bending sections 26 can be the same, such as plastic or rubber. The elastic connection sections 27 are configured to allow disconnection to expand the gap 201 and allow elastic stretching between the near-eye display assembly 10 and the electrical assembly 30. The elastic connection sections 27 provide the ability to stretch and contract in the length direction, so that the wire 20 is configured to run the bending sections 26 to stretch and contract in the length direction, to achieve the elastic connection between the near-eye display assembly 10 and the electrical assembly 30, effectively reducing the risk of insufficient overall elastic recovery caused by material wear of the bending sections 26 due to long-term use, thereby effectively improving the stability of the overall elastic recovery of the wire 20. When the user needs to further adjust the distance between the near-eye display assembly 10 and the electrical assembly 30, the elastic connection sections 27 can be disconnected or cut according to the needs with scissors or other tools. Of course, the elastic connection sections 27 can also be provided with a pre-opening path, that is, the user can increase the stretching force to disconnect the elastic connection sections 27. The elastic connection sections 27 allow the distance between the first end 21 and the second end 22 of the wire 20 to be further stretched, effectively improving the distance adjustment between the near-eye display assembly 10 and the electrical assembly 30. The elastic connection sections 27 located in the middle also play a supporting role when they are transverse, providing higher stability.

[0052] In some embodiments, the elastic connection sections 27 have a uniform length, which is beneficial for production and manufacturing. In other embodiments, the length of the elastic connection sections 27 located in the middle of the wire main body 28 is greater than the length of the elastic connection sections 27 at other positions of the wire main body 28; or the length of the elastic connection sections 27 gradually decreases from the middle of the wire main body 28 to the first end 21 and the second end 22; or the length of the elastic connection sections 27 gradually increases from the middle of the wire main body 28 to the first end 21 and the second end 22, and the relative distance between the elastic connection sections 27 and the corresponding bending sections 26 becomes shorter and shorter. In this way, the ends of the wire 20 can be more easily stretched. In some embodiments, the width, length and thickness of the elastic connection sections 27 can be the same, which is beneficial for production and manufacturing. Of course, they can also be different. In other embodiments, the elastic connection sections 27 can be made to fill the gap between the two main body sections 29, so that the user can cut (or disconnect) each elastic connection section 27 according to the needs, thereby achieving the stretching of the near-eye display module 1 at different positions. In this way, the user can disconnect or cut the elastic connection sections 27 at different positions according to the needs, thereby improving the stretching distance of the wire 20.

[0053] In some embodiments, referring toFigure 8 The wire 20 includes at least a sheathing layer 210, a first wire core 211, and a second wire core 212. The sheathing layer 210 can be made of plastic, rubber, silicone, or thermoplastic elastic material, etc. The first wire core 211 and the second wire core 212 are located within the sheathing layer 210 and are arranged side by side. The first wire core 211 and the second wire core 212 can be flexible metal conductive wire cores, and each of the first wire core 211 and the second wire core 212 can include positive and negative polarity metal fiber cores. The first wire core 211 and the second wire core 212 can be arranged side by side and electrically insulated from each other. In some embodiments, the wire 20 may also include a third or fourth wire core (not shown in the figure), which may be, for example, a data or signal transmission wire core. When other numbers of wire cores are included, multiple wire cores can be arranged side by side, and the side-by-side arrangement of wire cores can form a common plane, which is beneficial to the overall flatness of the wire 20 and facilitates storage. In the periodically bent adjacent bends 26: in the first bend 26, the first wire core 211 is closer to the gap 201 while the second wire core 212 is farther away from the gap 201; in the second bend 26, the first wire core 211 is farther away from the gap 201 while the second wire core 212 is closer to the gap 201. The arrangement of the first wire core 211 and the second wire core 212 can be periodically bent and arranged according to this rule, thereby making the wire 20 as a whole flattened; in addition, when the wire 20 is bent across the lens 100 and / or frame 110, the overall thickness or cross-section of the side of the wire 20 can fit the surface of the lens 100 and / or frame 110, for example... Figure 2 , 4 In example 9-11, the wire 20 does not easily cause excessive protrusion on the first side A and the second side B. For example, the first wire part 23 can fit the surface of the first side A of the lens 100 or the frame 110, the second wire part 24 can fit the surface of the second side B of the lens 100 or the frame 110, and the third wire part 25 fits the outer edge of the side of the lens 100 or the frame 110. This effectively reduces the discomfort to the eye caused by excessive protrusion of the wire 20, effectively improves the overall invisible design of the wire 20, and enhances the overall aesthetics after wearing.

[0054] In some embodiments, when the wire 20 is in its unfolded, folded state, the plane formed by the first wire core 211 and the second wire core 212 along the direction from the first end 21 to the second end 22 is coplanar with the plane formed by the periodic bending of the wire 20. This plane can be in the unfolded, folded state, and the plane where the first wire core 211 and the second wire core 212 are arranged and the plane where the first wire core 211 and the second wire core 212 are bent are the same plane. Figure 5 This is the unfolded state of wire 20 when it is not folded. Figure 3 This refers to the folded state of wire 20 after it has been bent. Figure 4 , 10-11 is the folded state of the wire 20 adhering to the lens; it can be understood that the faces formed by the arrangement of the wire core and the bending direction of the prior art are mostly non-parallel (or non-coplanar), for example, the prior art wire is a whole cylinder, or the face where the wire core is arranged and the face where the wire is bent are perpendicular to each other. Such non-parallel faces are easy to cause the overall thickness or cross section of the wire 20 to be too thick, especially after the wire 20 is bent to be located on the first side A and the second side B respectively, the prior art wire is not easy to adhere to the face of the lens 100 and / or the frame 110, which causes discomfort to the user and is too large in appearance, so the coplanar design of the wire 20 of the present application can effectively reduce the thicker side or cross section caused by the first wire core 211, the second wire core 212 or the bending, from Figure 2 、 4 , 9-11, the cross section of the wire 20 is small, and the area occupied by the wire 20 has little effect on the appearance and is not easy to be detected. The present application can adhere the folded wire 20 to the lens or other objects as much as possible, such as adhering to the surface of the lens, parallel or approximately parallel to each other, reducing the discomfort to the human eye on the near-eye side. When the near-eye display module 1 is hung on the lens and / or the frame, it is not easy to see. In addition, when the wire 20 is folded, the folding can be performed on the bending section 26, and the arrangement direction of the wire core 211 is in the form of a straight line. The folding can be performed on the straight line arrangement direction as the axis. The thickness is small and it is not easy to cause excessive damage to the internal wire core 211.

[0055] In some embodiments, the wire 20 can also be provided with a suction accessory (not shown in the figure), such as a micro suction cup or a magnetic sheet that can be magnetically attracted to each other, etc., so as to Figure 4 For example, the first wire part 23 and the second wire part 24 are provided with magnetic sheets that can be magnetically attracted to each other. The magnetic sheets can have a length extending along the length direction of the lens 100. The suction accessory can be located on the side of the wire 20 that adheres to the lens 100 and / or the frame 110 to contact, thereby facilitating the wire 20 to adhere more to the surface of the lens 100, effectively reducing the excessive protrusion of the wire 20, and improving the stability of the adhesion of the wire 20.

[0056] The total length of the wire 20 from the first end 21 to the second end 22 in the direction is not more than 5 cm, for example, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, etc. It is beneficial to the fine adjustment of the near-eye display assembly 10 and the electrical assembly 30 within the field of view angle range, effectively reducing the weight of the wire 20, further reducing the weight of the entire near-eye display module 1, and the small size and small volume are beneficial to the adaptation with the existing traditional glasses, without causing excessive weight, reducing the weight feeling of wearing.

[0057] Referring to Figure 2The application also provides a near-eye display device 1000, which comprises an optical lens 100 and the near-eye display module 1 as described in the above embodiments.

The user can place the near-eye display assembly 10, the wire 20 and the electrical module 30 on the frame body 110 and / or the lens 100 when needed, and can remove the near-eye display module 1 when not needed. The lens 100 can be a lens of myopia, hyperopia, sun, protective, sports glasses and the like. In some embodiments, the near-eye display device 1000 can further comprise a temple 120 and a frame body 110. The near-eye display module 1 can be adapted to ordinary eyes or lenses in a detachable manner, and the like, which effectively improves the application scenarios of the product.
