[0037] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0038] It is to be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element, with one or more intervening elements. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or indirectly connected or coupled to the other element, with one or more intervening elements.

[0039] It is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, specify relative positions and orientations as shown in the drawings, and are used only for the purpose of illustration and description, and do not indicate or imply that a device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed or implied to limit the application in its scope.

[0040] In addition, the terms "first", "second", and the like, are used only for descriptive purposes, and do not connote or imply relative importance or a quantity of the specified features. Thus, a feature defined with "first" or "second" can include one or more of the features. In the description of the application, the meaning of "a plurality" is two or more, unless otherwise explicitly specifically defined. The term "and / or" is used to describe the relationship between associated objects, which means that there can be three relationships; for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. In the description of the application, the term "one embodiment" or "some embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the application. Thus, the phrases "one embodiment", "some embodiments", "another embodiment", "additional embodiments" and the like appearing in various places in the specification are not necessarily all referring to the same embodiment, but can refer to one or more but not all embodiments, unless otherwise specifically noted. The terms "include", "contain", "have" and their variants mean "including but not limited to", unless otherwise specifically noted.

[0041] The electrical connection can include connection by wire, cable, welding, contact, etc. The electrical connection can realize the transmission of electric energy or / and signal. In the case of direct connection between A and B by wire, cable, welding, contact, etc., the electrical connection between A and B is considered as direct electrical connection; C is arranged between A and B, and the signal or current is transmitted to B through A and C in sequence, in which case the electrical connection between A and B is considered as indirect electrical connection. In this application, the electrical connection between A and B can be direct electrical connection between A and B, or indirect electrical connection between A and B.

[0042] The near-eye display module and the near-eye display device of the present application are described below in combination with FIGS. 1-21.

[0043] Referring to FIG. 1, the near-eye display module 01 according to the present application includes a housing 400, a control board assembly 300, a storage assembly 200, and a display assembly 100. It can be understood that the present application omits the schematic of the related electrical devices in the related drawings in order to facilitate the understanding of the related structure of the core components, for example, the resistors, capacitors, chips, inductors, etc. are omitted and not marked.

[0044] Specifically, the housing 400 is provided with a mounting space 401, and the housing 400 as a whole can be cylindrical, such as a circular cylinder or a prism or a circular truncated cone, etc. The radial diameter of the housing is less than or equal to 18 mm, for example, 18 mm, 17 mm, 16 mm, 15 mm, 14 mm, 13 mm, 12 mm, 11 mm, 10 mm, 9 mm, 8 mm, 7 mm. The height of the housing is less than or equal to 18 mm, for example, 18 mm, 17 mm, 16 mm, 15 mm, 14 mm, 13 mm, 12 mm, 11 mm, 10 mm, 9 mm, 8 mm, 7 mm. The control board assembly 300 is arranged in the mounting space 401. The control board assembly 300 is described in detail below.

[0045] The control board assembly 300 includes a main control board 310 and a conversion board 320, and the conversion board 320 is connected to the side of the main control board 310. There can be physical and mechanical connection between the main control board 310 and the conversion board 320, and the conversion board 320 is also electrically connected to the main control board 310. The main control board 310 can be provided with a main control unit 3111 and a main control sub-component 3112, etc., and the conversion board 320 can be provided with an electrical connection site, such as an electrical socket or a slot or an electrical plug contact, etc.

[0046] Referring to FIGS. 10 and 11, the viewing angle of FIG. 11 is opposite to that of FIG. 10, for example, when FIG. 10 is a structure schematic diagram of the control board assembly 300 under the front view angle, then FIG. 11 is a structure schematic diagram under the back view angle.

[0047] The control board assembly 300 comprises a main control board 310, an adapter board 320, an antenna board 330 and a power supply board. The power supply board can comprise a first power supply board 341 and a second power supply board 342.

[0048] Specifically, the adapter board 320 is connected to the main control board 310 through a first folding section 321, which is configured to allow folding to change the relative position of the adapter board 320 and the main control board 310. The adapter board 320 is provided with a first connection site 322, which is configured to be connected to an external device, such as the display assembly 100. The electronic components on the main control board 310 are electrically connected to the first connection site 322. In this way, by arranging the first connection site 322 on the adapter board 320 which is movable relative to the main control board 310, the thickness of the main control board 310 is not excessively large, and when the control board assembly 300 is assembled into an overall device, such as the near-eye display module 01, the position of the adapter board 320 is flexibly changed through the first folding section 321, which can avoid the overall device being excessively large in a single direction, and on the other hand, the compatibility of the control board assembly 300 to the installation environment is better. In addition, when welding electronic components, since the first connection site 322 and the main control board 310 are separated, the operation space is larger, which facilitates welding. The first connection site 322 can comprise a soldering point or an electrical socket, or the first connection site 322 can comprise a soldering point and an electrical socket.

[0049] The antenna board 330 is connected to the main control board 310 through a second folding section 331, which is configured to allow folding to change the relative position of the antenna board 330 and the main control board 310. The antenna board 330 is provided with an antenna 3301, which is configured to be connected in communication with an external device, which can be a smartphone, a computer, a tablet or smart glasses, a watch, etc. The near-eye display module 01 receives image content from the external device to display. The power supply board is connected to the main control board 310 through a third folding section 340, which is configured to allow folding to change the relative position of the power supply board and the main control board 310. The power supply board can adjust the current and voltage output by the power supply to provide to the electronic components on the control board assembly 300.

[0050] The control board assembly 300 has a first state and a second state. The control board assembly 300 is switched between the first state and the second state by unfolding or folding the first folding section 321, the second folding section 331 and the third folding section 340 to change the relative positions of the main control board 310, the adapter board 320, the antenna board 330 and the power board. As shown in FIG. 10 and FIG. 11, in the first state, the first folding section 321, the second folding section 331 and the third folding section 340 are unfolded, the control board assembly 300 is unfolded as a whole, and the adapter board 320, the power board, the antenna board 330 and the main control board 310 are in the same plane, which facilitates the installation of electronic components on the adapter board 320, the power board, the antenna board 330 and the main control board 310.

[0051] As shown in FIG. 13, in the second state, the first folding section 321, the second folding section 331 and the third folding section 340 are folded, the control board assembly 300 is folded as a whole, the adapter board 320, the power board and the antenna board 330 are located on one side of the main control board 310, and the angle between at least one of the adapter board 320, the power board and the antenna board 330 and the main control board 310 is greater than 0 degrees to form a receiving space 343 in which an external device is adapted to be received. In this way, the control board assembly 300 is switched to the second state to form a structure with a three-dimensional space, reducing the size of the control board assembly 300 in the plane of the main control board 310; the angle between at least one of the adapter board 320, the power board and the antenna board 330 and the main control board 310 is greater than 0 degrees, and the receiving space 343 is formed to receive the external device, avoiding the adapter board 320, the power board and the antenna board 330 being stacked in the thickness direction of the main control board 310 to cause the overall thickness of the control board assembly 300 to be too large after being connected with the external device. It should be noted that after being folded, the adapter board 320, the power board and the antenna board 330 are located on the same side of the main control board 310, that is, the adapter board 320, the power board and the antenna board 330 are not in the same plane as the main control board 310, and the angle between the adapter board 320, the power board, the antenna board 330 and the main control board 310 is less than 180 degrees.

[0052] According to the control board assembly 300 of the embodiments of the present application, the first folding section 321, the second folding section 331 and the third folding section 340 are folded so that the control board assembly 300 is folded as a whole to form a structure with a three-dimensional space, thereby reducing the size of the control board assembly 300 in a single plane; the included angle between at least one of the adapter board 320, the power supply board and the antenna board 330 and the main control board 310 is greater than 0 degrees, and a receiving space 343 for receiving external devices is formed, thereby avoiding the adapter board 320, the power supply board and the antenna board 330 being stacked in the thickness direction of the main control board 310 to cause the overall thickness of the control board assembly 300 to be too large after the control board assembly 300 is connected to external devices, and the space layout is optimized. In addition, the first connection position 322 is arranged on the adapter board 320 to be separated from the main control board 310, which can avoid the size of the control assembly in a single direction being too large after assembly, and the compatibility of the control board assembly 300 with the installation environment is better. When welding electronic components, the first connection position 322 is separated from the main control board 310, and the operation space is larger, thereby facilitating welding.

[0053] According to some embodiments of the present application, the main control board 310, the antenna board 330, the power supply board and the adapter board 320 each include a first face and a second face, and the first face and the second face are two opposite faces. As shown in FIGS. 10 and 11, the first face of the adapter board 320 is provided with the first connection position 322, and the second face of the adapter board 320 is not provided with components. As shown in FIG. 13, after the first folding section 321 is folded, the first face of the adapter board 320 is configured to face the first face of the main control board 310. The first face of the main control board 310 faces the receiving space 343, and the second face of the main control board 310 faces away from the receiving space 343. The first face of the main control board 310 is provided with the main control unit 3111 and the main control sub-component 3112, and the second face of the main control board 310 is provided with the power supply connection position 311, which is configured to be electrically connected to the battery 442 for power supply. The power supply connection position 311 includes a first polarity electric contact and a second polarity electric contact surrounding the first polarity electric contact, one of the first polarity electric contact and the second polarity electric contact is positive, and the other is negative, to correspond to the positive and negative poles of the battery 442.

[0054] The first face of the power supply board is provided with the power supply sub-component 3411, and the second face of the power supply board is not provided with components. The first face of the power supply board is configured to be folded to be arranged at an included angle with the first face of the main control board 310. The antenna 3301 is located on the first face or the second face of the antenna board 310. After the second folding section 331 is folded, the first face of the antenna board 330 is configured to be folded to be arranged at an included angle with the first face of the main control board 310.

[0055] According to some embodiments of the present application, the area of the adapter board 320 and the antenna board 330 is less than the area of the second power board 342 or the area of the first power board 341, and the area of the main control board 310 is greater than the area of the second power board 342 or the first power board 341. The area of the second power board 342, the area of the first power board 341, the area of the main control board 310 and the area of the antenna board 330 are all greater than the area of the second folding section 331 and the area of the third folding section 340.

[0056] As shown in FIG. 11, according to some embodiments of the present application, the first folding section 321, the second folding section 331 and the third folding section 340 all comprise flexible circuit boards, the width of the second folding section 331 is less than the width of the first folding section 321, and the width of the first folding section 321 is less than the width of the third folding section 340.

[0057] As shown in FIG. 11 and FIG. 12, which are schematic diagrams from the same perspective, the second folding section 331 is connected to one side of the main control board 310, and the width of the second folding section 331 is less than the length of the side connected thereto, so as to form an avoiding gap 344 between the main control board 310 and the antenna board 330. Thus, as shown in FIG. 3, after the second folding section 331 is folded, the avoiding gap 344 is still formed between the antenna board 330 and the main control board 310, so as to allow the external device to pass through, and avoid interference between the antenna board 330 and the external device in the accommodation space 343.

[0058] As shown in FIG. 12 and FIG. 13, according to some embodiments of the present application, the main control board 310 has opposite first and second sides, the first folding section 321 is connected to the first side, the second folding section 331 is connected to the second side, and the width of the second folding section 331 is less than the length of the second side. In the second state, the adapter board 320 and the antenna board 330 are opposite, that is, the avoiding gap 344 is opposite to the first side where the adapter board 320 is located. Thus, part of the structure of the external device connected to the first connecting position 322 can pass through the avoiding gap 344, so as to avoid interference with the antenna board 330.

[0059] As shown in FIG. 13, according to some embodiments of the present application, the first folding section 321 is in a strip shape, and in the second state, the first folding section 321 is folded, and the adapter board 320 is located in the receiving space 343, and the adapter board 320 at least partially overlaps the main control board 310 in the first direction, which is along the height direction of the control board assembly 300 (e.g., the up-down direction in FIG. 4). The adapter board 320 is opposite to and spaced apart from the main control board 310, and at this time, the first connecting position 322 faces the main control board 310 or is away from the main control board 310. In this way, when the external device is connected to the first connecting position 322, the external device can be in contact with the main control board 310 to play a supporting role, so that the connection is more stable. The part of the structure of the external device that is spaced apart from the adapter board 320 and the main control board 310 can be clamped between the adapter board 320 and the main control board 310. As shown in FIG. 4, in some embodiments, in the second state, the adapter board 320 is parallel or substantially parallel to the main control board 310, and the first connecting position 322 is located on the side of the adapter board 320 facing the main control board 310.

[0060] Referring to FIG. 12, according to some embodiments of the present application, the adapter board 320, the power board, and the antenna board 330 are spaced apart along the circumferential direction of the main control board 310. In this way, after the first folding section 321, the second folding section 331, and the third folding section 340 are folded, the mutual interference of any two of the adapter board 320, the power board, and the antenna board 330 can be avoided, and the mutual interference between the adapter board 320, the power board, and the antenna board 330 can also be avoided.

[0061] As shown in FIG. 10 and FIG. 13, according to some embodiments of the present application, the power board includes a first power board 341 and a second power board 342, the first power board 341 is connected to one side edge of the main control board 310, and the second power board 342 is connected to the other side edge of the main control board 310, and in the second state, the first power board 341 and the second power board 342 are opposite. In some embodiments, the main control board 310 is substantially square, and the power board includes two power boards, including the first power board 341 and the second power board 342, and the first power board 341, the adapter board 320, the second power board 342, and the antenna board 330 are sequentially and spaced apart along the circumferential direction of the main control board 310. The first power board 341 and the second power board 342 are opposite, and in the first state, the first power board 341 and the second power board 342 are located in the same plane, and in the second state, the first power board 341 and the second power board 342 are parallel or substantially parallel. The adapter board 320 and the antenna board 330 are located on a pair of opposite side edges of the main control board 310, and the first power board 341 and the second power board 342 are located on another pair of opposite side edges of the main control board 310.

[0062] The first surface of the first power board 341 and the first surface of the second power board 342 are respectively provided with power sub-components 3411, 3421, which can include resistors, capacitors, inductors, switching tubes, amplifiers, etc. The second surface of the first power board 341 and the second surface of the second power board 342 are not provided with components, i.e., the electronic components on the first power board 341 and the second power board 342 are arranged on the side of the power boards facing the storage space 343, ensuring that the side provided with components faces the storage space 343, and the side not provided with components faces the side wall of the shell 400, thereby reducing damage to the electrical components during assembly. The first surface of the first power board 341 and the first surface of the second power board 342 are respectively configured to be folded to an angle with the first surface of the main control board 310, e.g., perpendicular to each other or less than 90°. In some embodiments, the side of the first power board 341 facing away from the storage space 343, the side of the second power board 342 facing away from the storage space 343, and the side of the antenna board 330 facing away from the storage space 343 are all provided with reinforcing plates to support the first power board 341, the second power board 342, and the antenna board 330 and improve their structural strength.

[0063] As shown in FIG. 13, in the second state, the angles between the first power board 341, the second power board 342, the antenna board 330, and the main control board 310 are all greater than 0 degrees, the adapter board 320 is parallel to the main control board 310 and spaced apart by a certain distance, the first power board 341, the second power board 342, and the antenna board 330 together with the main control board 310 define a storage space 343, which is generally cubic. The electronic components on the main control board 310 are arranged on the side of the main control board 310 facing the storage space 343, the electronic components on the power boards are arranged on the side of the power boards facing the storage space 343, and the electronic components on the antenna board 330 can also be arranged on the side of the antenna board 330 facing the storage space 343 to protect the electronic components.

The storage chip 211 and the third connection site 221 are located on different faces, so that when the fifth folding section 212 is folded, one of the storage chip 211 and the third connection site 221 is located in the storage space, and the other is located outside the storage space, thereby avoiding the situation that both of them are located in the storage space and interfere with the external device stored in the storage space. As shown in FIG. 9, in some embodiments, in the folded state, the storage chip 211 is located on the side of the first plate body 210 away from the storage space, so as to avoid interference between the storage chip 211 and the external device in the storage space; the third connection site 221 is located in the storage space, so as to shorten the distance from the external device in the storage space and facilitate connection. The third connection site 221 can be directly connected with the external device.

[0099] According to some embodiments of the present application, the second plate body 220 is provided with a reinforcing member. The reinforcing member can be in the form of a plate. The third connection site 221 is located on one side of the second plate body 220, and the reinforcing member is located on the other side opposite to the one side of the second plate body 220, that is, the third connection site 221 and the reinforcing member are located on opposite sides of the second plate body 220. The reinforcing member can support and protect the third connection site 221. The reinforcing member can be bonded to the second plate body 220. The area of the side of the reinforcing member connected with the second plate body 220 is greater than or equal to the area of the side of the second plate body 220 provided with the third connection site 221. In some embodiments, the reinforcing member and the second plate body 220 are integrally formed.

[0100] As shown in FIG. 18, the near-eye display module 01 according to the embodiments of the present application includes a display assembly 100 and a storage assembly 200.

[0101] Specifically, the storage assembly 200 is in the folded state, and the storage assembly 200 forms a storage space 343. The display assembly 100 is connected with the storage assembly 200 to obtain image information in the storage assembly 200. The storage assembly 100 is provided with a storage connection site, the storage connection site is connected with the third connection site 221, and the display assembly 100 is arranged in the storage space to facilitate connection with the third connection site 221. In this way, by assembling the storage assembly 200 in the folded state to the near-eye display module 01, the display assembly 100 is stored in the storage space, the third connection site 221 and the storage chip 211 are arranged on different planes, the space of the storage assembly 200 is fully utilized, and the overall volume of the near-eye display assembly is prevented from being excessively large due to the excessively large size of the storage assembly 200 in a single direction.

[0102] As shown in FIG. 9 and FIG. 19, when the accommodation angle is 90 degrees, the plane where the storage chip 211 is located is perpendicular to the plane where the third connecting position 221 is located, the third connecting position 221 is located in the accommodation space, the storage chip 211 is located on the side of the first plate body 210 away from the accommodation space, the display assembly 100 is arranged in the accommodation space and connected with the third connecting position 221 on the second plate body 220, the thickness direction of the display is the same as the thickness direction of the second plate body 220, and the thickness direction of the storage chip 211 and the first plate body 210 is perpendicular to the thickness direction of the second plate body 220, thereby avoiding the size of the storage assembly 200 and the display assembly 100 in a single direction after being connected, and reducing the volume of the near-eye display module 01.

[0103] As shown in FIG. 19, the display assembly 100 is parallel or substantially parallel to the second plate body 220, and the display assembly 100 and the second plate body are arranged in a stack, the storage connecting position is arranged on the side of the display assembly 100 facing the second plate body 220, and after the display assembly 100 is installed in the accommodation space, the storage connecting position is in contact with and connected with the third connecting position 221. The display assembly 100 is arranged in a spaced manner with the first plate body 210, and the light emitting direction of the display assembly 100 is away from the second plate body 220. As shown in FIG. 18 and FIG. 19, the display assembly 100 has a light emitting surface 114, and the light emitting surface 114 is arranged away from the second plate body 220.

[0104] As shown in FIG. 18 and FIG. 19, the near-eye display module 01 further comprises a housing 400 and a main control board 310, the housing 400 is provided with a mounting space, the main control board 310, the display assembly 100 and the storage assembly 200 are arranged in the mounting space, the housing 400 is further provided with a light transmission portion 411, the light transmission portion 411 is opposite to the light emitting surface 114 of the display assembly 100, and an optical assembly 440 is arranged between the light transmission portion 411 and the display assembly 100. The optical assembly 440 is configured to receive light from the light emitting surface 114 and allow the light to be reflected and emitted after being reflected therein, and the light emitted from the light emitting surface 114 of the display assembly 100 projects a virtual image through the optical assembly 440 and the light transmission portion 411. The main control board 310 is connected with the display assembly 100, and as shown in FIG. 19, the main control board 310 can be folded and substantially cuboid, and the storage assembly 200 and the display assembly 100 can be accommodated in the main control board 310 to fully utilize the mounting space and reduce the volume of the near-eye display module 01.

[0105] As shown in FIG. 18 and FIG. 19, in some embodiments, the height of the display assembly 100 is less than the height of the first plate body 210, that is, the light exit surface 114 of the display assembly 100 does not protrude from the first plate body 210 in the height direction, and part of the optical assembly 440 can be located in the receiving space, so that the first plate body 210 can be increased in the limited space inside the housing 400, providing sufficient mounting position for the storage chip 211, while avoiding the size of the near-eye display module 01 being too large in the height direction.

[0106] In the storage assembly 200, the second plate body 220 is connected to the first plate body 210. After folding the fifth folding section 212, the first plate body 210 is configured to be non-parallel to the second plate body 220, the storage assembly 200 is folded to form a folded storage assembly 200; the display assembly 100 is folded to form a folded display assembly 100; the shape of the folded storage assembly 200 is different from the shape of the folded display assembly 100, and the storage assembly 200 can be foldable. It can be understood that the first plate body 210 can be folded relative to the second plate body 220, for example, the storage assembly 200 is folded into an L shape when viewed from the side, etc., or the first plate body 210 can be unfolded relative to the second plate body 220, so that the first plate body 210 and the second plate body 220 are coplanar or approximately coplanar, and the display module 100 can be foldable, for example, the display module 100 is folded into a U shape when viewed from the side. Or, when the display module 100 is folded, the first base 110 is parallel or approximately parallel to the second base 120; wherein the storage chip 211 can include a random access memory (RAM) or a read-only memory (ROM), such as a flash memory, an electrically erasable programmable read-only memory (EEPROM), wherein the storage chip 211 can store a driver or image data required to be displayed on the micro display 111, such as a control program for driving the light emission of the micro display 111 or a bottom map of a certain image frame, etc., so that the micro display 111 can realize the expected image display in a short time, and in some embodiments, the host board can be provided with related light sensors or human-computer interaction sensors (such as inertial sensors, etc.), and some pre-stored sensor data can be stored in advance, and in other embodiments, some basic data packets or communication data packets for subsequent firmware upgrade can also be stored, which can be called by the host unit to improve work efficiency.

[0107] When the first folding section 321 is folded, the adapter plate 320 is configured to at least partially overlap the main control plate 310 in a first direction. The first direction can be the axial direction of the shell 400. It can be understood that the size of the adapter plate 320 can be smaller than the main control plate 310. The adapter plate 320 can be moved, flipped or folded relative to the main control plate 310 by folding the first folding section 321, so that the adapter plate 320, the first folding section 321 and the main control plate 310 form a U-shaped structure in a side view. In some embodiments, after the first folding section 321 is folded, the adapter plate 320 can be fully projected onto the main control plate 310 in the first direction, or after the first folding section 321 is folded, the adapter plate 320 can be partially exposed or offset relative to the main control plate 310, so that only part of the adapter plate 320 is projected onto the main control plate 310 in the first direction. In some embodiments, after the first folding section 321 is folded, the adapter plate 320 can be parallel or substantially parallel to the main control plate 310. In some embodiments, the adapter plate 320 can be moved, flipped or unfolded relative to the main control plate 310 by unfolding the first folding section 321, so that the adapter plate 320 is coplanar or substantially coplanar with the main control plate 310. In other embodiments, the adapter plate 320 can be kept in the folded state relative to the main control plate 310, for example, by external shells or clamping members, adhesive members, etc. to keep it fixed, or by curing with insulating glue or epoxy resin to keep it in the folded state. It should be understood that the related folding descriptions in the subsequent embodiments can be kept in the folded state after assembly.

[0108] The second base 120 is configured to at least partially overlap the first base 110 in the first direction after folding the fourth folding section 113. It can be understood that the second base 120 and the first base 110 can have the same or approximately the same area. After folding the fourth folding section 113 to move, flip or fold the second base 120 relative to the first base 110, the second base 120 can be fully projected onto the first base 110 in the first direction, or after folding the fourth folding section 113, the second base 120 and the first base 110 can be partially misaligned, resulting in the second base 120 and the first base 110 being partially projected in the first direction. In some embodiments, after folding the fourth folding section 113, the second base 120 and the first base 110 can be parallel or approximately parallel to each other. The second base 120 can be moved, flipped or folded relative to the first base 110 by folding the fourth folding section 113, so that the second base 120, the fourth folding section 113 and the first base 110 form a shape similar to a U shape in a side view. The folding structure formed by moving, flipping, folding or unfolding the fourth folding section 113 relative to the first base 110 can be the same as or similar to the folding structure formed by moving, flipping, folding or unfolding the first folding section 321 relative to the main control board 310. In some embodiments, the second base 120 can be moved, flipped or unfolded relative to the first base 110 by unfolding the fourth folding section 113, so that the second base 120 and the first base 110 are unfolded to the same plane or approximately coplanar. In other embodiments, the second base 120 can also remain in the folded state relative to the first base 110. The second board body 220 is configured to be located between the main control board 310 and the second base 120 and electrically connect the storage chip 211 and the micro display 111. The second board body 220 can be connected between the main control board 310 and the second base 120 by means such as electrical plug-in or welding. The first base 110 and the second base 120 are configured to hold the adapter board 320 and electrically connect the micro display 111 and the main control board 310. The adapter board 320 and the first base 110 can be connected to each other by means such as electrical plug-in or welding. The light exit surface 114 of the micro display 111 faces away from the adapter board 320 in the first direction.

[0109] The assembly process of the above components can be understood as follows: first, the second base 120 and the adapter plate 320 are connected, then the first folding section 321 is folded to move, turn or fold the adapter plate 320, so that the adapter plate 320 and the main control plate 310 overlap each other, and the first surface of the adapter plate 320 faces the main control plate 310, the first base 110 is moved, turned or folded relative to the second base 120 to ensure that the light emitting surface 114 of the micro display 111 faces upward, then the second plate body 220 is inserted into the side of the second base away from the adapter plate 320. From the final assembled complete form, in the first direction along the light emitting direction of the micro display 111, the main control plate 310, the second plate body 220, the second base 120, the adapter plate 320, the first base 110 and the micro display 111 are sequentially stacked, and since the control plate assembly 300, the display assembly 100 and the storage assembly 200 can be independently designed and manufactured with circuit boards, the cost is lower than that of a whole larger area circuit board.

[0110] In some application scenarios, for a near-eye display module with simple functions, the storage assembly 200 is generally arranged on the same circuit board as the control board assembly 300 and then folded and assembled, but as the functions increase, the thickness and width of the storage chip 211 of the storage assembly 200 also need to be increased accordingly. If the folding is simply performed, the height of the near-eye display module will be too high. In combination with the use scenario of the near-eye display, if the near-eye display module is directly directed to the side of the human eye, the relatively large thickness of the near-eye display module is easy to cause the feeling of being poked by a foreign object to the eyes, that is, the near-eye display module is too thick and too close to the eyes, which makes people feel uncomfortable. The present application effectively reduces the thickness caused by the storage assembly 200 by moving, flipping or folding the first board body 210 of the storage assembly 200 to the side of the main control board 310. The folding structure formed by moving, flipping, folding or unfolding the adapter board 320 in the control board assembly 300 relative to the first folding section 321 of the main control board 310 is similar to the folding structure formed by moving, flipping, folding or unfolding the first base 110 in the display assembly 100 relative to the fourth folding section 113 of the second base 120. The folding structure formed by moving, flipping, folding or unfolding the first board body 210 in the storage assembly 200 relative to the fifth folding section 212 of the second board body 220 is different from the folding structure formed by moving, flipping, folding or unfolding the first base 110 in the display assembly 100 relative to the fourth folding section 113 of the second base 120. Therefore, the space can be fully utilized by the respective structures, and the space generated by the different structures after the folding of different components can be used to place other components. Part of the electronic components are arranged in a direction different from the arrangement direction of the control board assembly 300, the storage assembly 200 and the display assembly 100, which effectively avoids the problem that the size of the near-eye display module 01 in a single direction is too large due to the large size of the three components in a single direction after being connected, and ensures that the size of the entire assembled module is minimized.

[0111] In some embodiments, the first folding section 321 can be part of the adapter board 320. When the first folding section 321 is part of the adapter board 320, the adapter board 320 is foldable, and in this case, folding or unfolding the first folding section 321 is equivalent to folding or unfolding the adapter board 320. In certain embodiments, the first folding section 321 can have a relatively short length.

[0112] In some embodiments, the second folding section 331 can be part of the antenna board 330.

In certain embodiments, the second folding section 331 can have a relatively short length.

[0113] In some embodiments, the third folding segment 340 can be part of the first power panel 341 or part of the second power panel 342. When the third folding segment 340 is part of the first power panel 341, the first power panel 341 is foldable, in which case folding or unfolding the third folding segment 340 is folding or unfolding the first power panel 341. When the third folding segment 340 is part of the second power panel 342, the second power panel 342 is foldable, in which case folding or unfolding the third folding segment 340 is folding or unfolding the second power panel 342. In certain embodiments, the third folding segment 340 can have a shorter length.

[0114] In some embodiments, the fourth folding segment 113 can be part of the first base 110 or part of the second base 120. When the fourth folding segment 113 is part of the first base 110, the first base 110 is foldable, in which case folding or unfolding the fourth folding segment 113 is folding or unfolding the first base 110. When the fourth folding segment 113 is part of the second base 120, the second base 120 is foldable, in which case folding or unfolding the fourth folding segment 113 is folding or unfolding the second base 120. In certain embodiments, the fourth folding segment 113 can have a shorter length.

[0115] In some embodiments, the fifth folding segment 212 can be part of the first panel body 210 or part of the second panel body 220. When the fifth folding segment 212 is part of the first panel body 210, the first panel body 210 is foldable, in which case folding or unfolding the fifth folding segment 212 is folding or unfolding the first panel body 210. When the fifth folding segment 212 is part of the second panel body 220, the second panel body 220 is foldable, in which case folding or unfolding the fifth folding segment 212 is folding or unfolding the second panel body 220. In certain embodiments, the fifth folding segment 212 can have a shorter length.

[0116] In some embodiments, referring to FIGS. 1-15, the first power board 341 and the second power board 342 are provided with power supply circuits, such as voltage boosting circuits, voltage reducing circuits, voltage stabilizing circuits, driving circuits, and the like. The above-mentioned circuits can further include corresponding micro processing chips, resistors, capacitors, inductors, switching tubes, amplifiers, and the like. The first power board 341 and the second power board 342 are arranged at intervals, and are electrically connected to the main control board 310. After folding the third folding section 340, each of the first power board 341 and the second power board 342 is configured to be non-parallel to the main control board 310, and the first power board 341 and the second power board 342 are located on different planes. The first power board 341, the second power board 342, and the main control board 310 form a storage space 343. It can be understood that the first power board 341, the main control board 310, and the second power board 342 collectively enclose the storage space 343. As shown in FIG. 15, the display assembly 100 and the storage assembly 200 are located in the storage space 343. The height of the micro display 111 is lower than the height of the storage space 343, and the micro display 111 does not protrude from the storage space 343. That is, after folding and assembling, the height of the micro display 111 is lower than the height of the first power board 341 and the height of the second power board 342. The light of the micro display 111 is emitted from the storage space 343, so that the internal space of the shell 400 can be fully utilized, and the height dimension of the micro display 111, the first power board 341, and the second power board 342 is reduced.

[0117] In some embodiments, referring to FIGS. 1-15, the antenna board 330 is connected to the side edge of the main control board 310 and is arranged at intervals from the first power board 341 and the second power board 342. The antenna board 330 is configured to be folded to be non-parallel to the main control board 310 and to be on a different plane from the first power board 341 and the second power board 342. The antenna board 330 is electrically connected to the main control board 310. The height of the micro display 111 is lower than the height of the antenna board 330. It can be understood that the antenna board 330, the first power board 341, the second power board 342, and the main control board 310 collectively enclose the storage space 343. The first power board 341 and the second power board 342 can be arranged oppositely or adjacently. The antenna board 330 can be arranged adjacently to the first power board 341, or the antenna board 330 can be arranged adjacently to the second power board 342. The antenna board 330 is provided with an antenna 3301 and is configured to be communicatively connected to an external device. The external device can be a smart phone, a computer, a tablet, smart glasses, a smart watch, or the like. The near-eye display module 01 receives image content from the external device and displays the image content.

[0118] In some embodiments, the near-eye display module 01 further comprises a battery 442, which can be a rechargeable battery or a disposable battery, and can be a button battery or a ring battery, etc. The battery 442 is electrically connected to the main control board 310, the first power board 341 and the second power board 342 to supply power to all the electronic devices. The battery 442 is located on the side of the main control board 310 away from the second board body 220, and is parallel or substantially parallel to the main control board 310, so as to reduce the radial size caused by the combination of the power board, that is, to make full use of the space of the shell and ensure the miniaturization of the near-eye display module.

[0119] In some embodiments, with reference to FIGS. 1-15, the near-eye display module 01 further comprises a first folding section 321, a second folding section 331, a third folding section 340, a fourth folding section 113 and a fifth folding section 212, which can be folded or unfolded. Each of the folding sections can be formed by hinging two electrically connected boards, or can be formed by a flexible wire or a flexible printed circuit board. As shown in FIGS. 10-15, the adapter board 320 is connected to the main control board 310 through the first folding section 321, the antenna board 330 is connected to the main control board 310 through the second folding section 331, and the first power board 341 and the second power board 342 are connected to the main control board 310 through the third folding section 340. The antenna board 330, the first power board 341, the adapter board 320 and the second power board 342 are spaced apart along the circumference of the main control board 310 to effectively avoid interference between the adapter board 320, the power boards and the antenna board 330 in the folded state. As shown in FIGS. 10-12, after the second folding section 331, the third folding section 340 and the first folding section 321 are unfolded, the antenna board 330, the first power board 341, the adapter board 320 and the second power board 342 are coplanar or substantially coplanar with the main control board 310. The electronic components on the antenna board 330 can also be arranged on the side of the antenna board 330 facing the storage space 343, so as to protect the electronic components.

[0120] The first base 110 is connected with the second base 120 through the fourth folding section 113. The first base 110 and the second base 120 can be plate-shaped. As shown in FIG. 6, the second base 120 is also configured to be folded to be coplanar with the first base 110. The first base 110, the fourth folding section 113 and the second base 120 can be in a linear shape. The first base 110 and the second base 120 can move relative to each other to fold or unfold the display assembly 100, facilitating assembly. As shown in FIG. 6, in the third folding state, the first base 110, the fourth folding section 113 and the second base 120 are connected in sequence and on the same straight line, so that the display assembly 100 is in a linear shape. At this time, the first base 110 and the second base 120 are separated, and the display assembly 100 is unfolded, thereby facilitating the installation of the micro display 111, the fourth connecting site 121 and the second connecting site 122 on the first base 110 or the second base 120. The width of the fourth folding section 113 is less than the width of the first base 110 and less than the width of the second base 120, so as to reduce the space occupied by the fourth folding section 113 and facilitate storage.

[0121] Referring to FIG. 7 and FIG. 14, according to some embodiments of the present application, the thickness of the first base 110 is L1, the thickness of the second base 120 is L2, and the length of the fourth folding section 113 is greater than L1+L2, so that in the third unfolded state, the first base 110 and the second base 120 can be spaced apart, and a connecting space is formed between the first base 110 and the second base 120. The connecting space can accommodate other devices connected with the display assembly 100. At this time, the fourth connecting site 121 or the second connecting site 122 can be arranged on the side of the second base 120 facing the first base 110, so as to be directly connected with the device, reducing the connection components and saving space.

[0122] In some embodiments, the first folding section 321, the second folding section 331, the third folding section 340, the fourth folding section 113 and the fifth folding section 212 can be flat. In order to electrically connect different components, the first folding section 321, the second folding section 331, the third folding section 340, the fourth folding section 113 and the fifth folding section 212 can be respectively printed with conductive lines having different numbers and types of electrical properties. The first folding section 321, the second folding section 331, the third folding section 340, the fourth folding section 113 and the fifth folding section 212 have different widths. The width of the first folding section 321 is greater than the width of the second folding section 331. The width of the third folding section 340 is greater than the width of the first folding section 321. The width of the fifth folding section 212 is greater than or equal to the width of the fourth folding section 113.

[0123] According to the display assembly 100 of the present application, the micro display 111 and the connection positions of the fourth connection position 121 and the second connection position 122 are separated by the first base 110 and the second base 120, and in the third folded state, the display assembly 100 is unfolded, facilitating the welding and installation of the micro display 111 and the fourth connection position 121 and the second connection position 122 during the manufacturing process. Moreover, the display assembly 100 can be switched to the third unfolded state by the fourth folding section 113, and the first base 110 and the second base 120 are stacked by folding the fourth folding section 113. The micro display 111 is separated from the fourth connection position 121 and the second connection position 122, facilitating assembly, breaking the limitation of the single base structure, and being more space-efficient and flexible in space arrangement, avoiding the inconvenience of assembly caused by the excessive size in a single direction.

[0124] The second plate body 220 is connected to the first plate body 210 through the fifth folding section 212, as shown in FIG. 8, after unfolding the fifth folding section 212, the first plate body 210 is also configured to be coplanar or substantially coplanar with the second plate body 220, at this time, the second plate body 220, the fifth folding section 212 and the first plate body 210 can be in a linear type.
