Abstract

This application provides a control board assembly and a near-eye display module. The control board assembly includes a main control board, an adapter board, an antenna board, and a power supply board. The adapter board is connected to the main control board via a first folding section, the antenna board is connected to the main control board via a second folding section, and the power supply board is connected to the main control board via a third folding section. The control board assembly has a first state and a second state. In the first state, the adapter board, power supply board, antenna board, and main control board are all in the same plane. In the second state, the first, second, and third folding sections are all folded, and at least one of the adapter board, power supply board, and antenna board has an angle greater than 0 degrees with the main control board to form a storage space, in which external devices are suitable for storage. By folding the control board assembly to form a structure with three-dimensional space, its size in a single plane is reduced, avoiding excessive overall thickness after the control board assembly is connected to external devices, thus optimizing the spatial layout.

Description

[0001] This application claims priority to U.S. Patent Application No. 18 / 806768, filed August 16, 2024, entitled “Near-eye Display Module and Near-eye Display Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of near-eye display technology, and more particularly to a control board assembly and a near-eye display module. Background Technology

[0003] Intelligent near-eye display devices, such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) (e.g., AR glasses, VR glasses), can provide users with digital experiences, such as visual content display and auditory audio transmission. Augmented Reality can overlay virtual information onto the physical world. These near-eye display devices or modules project a distant virtual image from pixels on the display into the user's eye through a series of optical imaging elements. However, in related technologies, the internal structure design of near-eye display modules is unreasonable, resulting in large sizes and weights, making them inconvenient for prolonged wear. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the related art. To this end, this application provides a control board assembly, comprising:

[0005] Main control board;

[0006] An adapter board is connected to the main control board via a first folding section, the first folding section being configured to allow folding, and the adapter board having a first connection position for connecting external devices;

[0007] An antenna board, which is connected to the main control board via a second folding section, the second folding section being configured to allow folding;

[0008] A power board is connected to the main control board via a third folding section, the third folding section being configured to allow folding; an antenna is provided on the antenna board, the antenna being configured to communicate with external devices.

[0009] The control board assembly has a first state and a second state. In the first state, the first folding segment, the second folding segment, and the third folding segment are all unfolded, and the adapter board, the power board, the antenna board, and the main control board are all in the same plane.

[0010] In the second state, the first folding segment, the second folding segment, and the third folding segment are all folded. The adapter board, the power board, and the antenna board are all located on one side of the main control board. The angle between the adapter board, the power board, the antenna board, and the main control board is greater than 0 degrees to form a storage space. The external device is suitable for storage in the storage space.

[0011] This application also provides a near-eye display module, including:

[0012] A display assembly, wherein the display assembly is provided with a control board connection position;

[0013] As described above, the control board assembly is in a second state, the display assembly is disposed within the storage space, the control board connection position is connected to the first connection position, and the height of the display assembly is less than the height of the power board.

[0014] The control board assembly and near-eye display module provided in this application fold the control board assembly as a whole by folding the first folding segment, the second folding segment and the third folding segment, forming a structure with three-dimensional space, reducing its size in a single plane; at least one of the adapter board, power board and antenna board has an angle greater than 0 degrees with the main control board, forming a storage space for external devices, avoiding the stacking of the adapter board, power board and antenna board in the thickness direction of the main control board, which would cause the overall thickness of the control board assembly to be too large after connecting with external devices, thus optimizing the space layout.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] The following is combined with Figures 1-21 This application describes the eye display module and near-eye display device.

[0043] See Figure 1 As shown, the near-eye display module 01 implemented according to this application includes a housing 400, a control board assembly 300, a storage assembly 200, and a display assembly 100. It is understood that, for ease of understanding of the relevant structure of the core components, this application has omitted schematic representations of relevant electrical devices in the related illustrations, such as resistors, capacitors, chips, and inductors.

[0044] Specifically, the housing 400 has an installation space 401 within it. The housing 400 can be cylindrical, such as a cylinder, prism, or frustum. 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, or 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, or 7 mm. The control board assembly 300 is located within the installation 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 an adapter board 320. The adapter board 320 is connected to the side of the main control board 310. There can be physical and mechanical connections between the main control board 310 and the adapter board 320, and the adapter board 320 is also electrically connected to the main control board 310. The main control board 310 may have a main control unit 3111 and main control sub-components 3112, etc., while the adapter board 320 may have electrical connection positions, such as electrical sockets, slots, or electrical contact points, etc.

[0046] See Figure 10 and Figure 11 As shown, where Figure 11 perspective and Figure 10The perspectives are opposite, for example, when Figure 10 This is a structural schematic diagram of the control board assembly 300 from a frontal view. Figure 11 This is a schematic diagram of the structure from the rear view.

[0047] The control board assembly 300 includes a main control board 310, an adapter board 320, an antenna board 330, and a power supply board. The power supply board may include 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 via a first folding section 321. The first folding section 321 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 has a first connection position 322 configured for connecting external devices, such as the display assembly 100. Electronic components on the main control board 310 are electrically connected to the first connection position 322. By placing the first connection position 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 avoided. When assembling the control board assembly 300 onto the overall device, such as the near-eye display module 01, the position of the adapter board 320 can be flexibly changed via the first folding section 321. This avoids excessive size of the overall device in a single direction and improves the compatibility of the control board assembly 300 with the installation environment. Furthermore, when soldering electronic components, the separation of the first connection position 322 and the main control board 310 provides more operating space and facilitates soldering. The first connection position 322 may include a soldering point or an electrical socket, or the first connection position 322 may include a soldering point and an electrical socket.

[0049] Antenna board 330 is connected to main control board 310 via a second folding section 331, which is configured to allow folding to change the relative position of antenna board 330 and main control board 310. Antenna board 330 is equipped with antenna 3301, which is configured to communicate with external devices, such as smartphones, computers, tablets, smart glasses, watches, etc. Near-eye display module 01 receives image content from external devices for display. Power board is connected to main control board 310 via a third folding section 340, which is configured to allow folding to change the relative position of power board and main control board 310. Power board can regulate the current and voltage output to supply power to electronic components on control board assembly 300.

[0050] The control board assembly 300 has a first state and a second state. By unfolding or folding the first folding segment 321, the second folding segment 331, and the third folding segment 340, the relative positions of the main control board 310, the adapter board 320, the antenna board 330, and the power supply board are changed, thereby switching the control board assembly 300 between the first and second states. Figure 10 and Figure 11 As shown, in the first state, the first folding section 321, the second folding section 331, and the third folding section 340 are all unfolded, and the control board assembly 300 is fully unfolded. The adapter board 320, the power board, the antenna board 330, and the main control board 310 are all 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] like Figure 13 As shown, in the second state, the first folding segment 321, the second folding segment 331, and the third folding segment 340 are all folded, and the control board assembly 300 is folded as a whole. The adapter board 320, the power board, and the antenna board 330 are all located on one side of the main control board 310. At least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310 to form a storage space 343, in which external devices are suitable for storage. In this way, switching the control board assembly 300 to the second state forms a structure with a three-dimensional space, reducing its size in the plane where the main control board 310 is located. At least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310, forming a storage space 343 for storing external devices. This avoids the adapter board 320, the power board, and the antenna board 330 from being stacked in the thickness direction of the main control board 310, which would cause the overall thickness of the control board assembly 300 to be too large after being connected to external devices. It should be noted that after folding, the adapter board 320, power board, and antenna board 330 are all located on the same side of the main control board 310. That is to say, the adapter board 320, power board, and antenna board 330 are not in the same plane as the main control board 310, and the included angle between the adapter board 320, power board, antenna board 330 and the main control board 310 is less than 180 degrees.

[0052] According to the embodiments of this application, the control board assembly 300 is folded as a whole by folding the first folding segment 321, the second folding segment 331, and the third folding segment 340, forming a structure with three-dimensional space and reducing its size in a single plane. At least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310, forming a storage space 343 for accommodating external devices. This avoids the adapter board 320, the power board, and the antenna board 330 from being stacked in the thickness direction of the main control board 310, which would result in an excessively large overall thickness of the control board assembly 300 after connection with external devices, thus optimizing the spatial layout. In addition, by setting the first connection position 322 on the adapter board 320 to be separate from the main control board 310, it can avoid the control components from being too large in a single direction after assembly, and the control board assembly 300 has better compatibility with the installation environment. When soldering electronic components, since the first connection position 322 is separated from the main control board 310, the operating space is larger, which facilitates soldering.

[0053] According to some embodiments of this application, the main control board 310, antenna board 330, power supply board, and adapter board 320 each include a first surface and a second surface, wherein the first surface and the second surface are two opposing surfaces. For example, Figure 10 and Figure 11 As shown, the first surface of the adapter board 320 has a first connection position 322, and the second surface of the adapter board 320 has no components. See also Figure 13 As shown, after folding the first folding segment 321, the first surface of the adapter plate 320 is configured to face the first surface of the main control board 310. The first surface of the main control board 310 faces the storage space 343, and the second surface of the main control board 310 faces away from the storage space 343. The first surface of the main control board 310 is provided with a main control unit 3111 and a main control sub-component 3112, and the second surface of the main control board 310 is provided with a power connection position 311. The power connection position 311 is configured to be electrically connected to the battery 442 for power supply. The power connection position 311 includes a first polarity electrical contact and a second polarity electrical contact surrounding the first polarity electrical contact. One of the first polarity electrical contact and the second polarity electrical contact is a positive terminal, and the other is a negative terminal, corresponding to the positive and negative terminals of the battery 442.

[0054] The first side of the power board has a power sub-component 3411, while the second side of the power board has no components. The first side of the power board is configured to be folded so that it forms an angle with the first side of the main control board 310. The antenna 3301 is located on either the first or second side of the antenna board 310. After folding the second folding segment 331, the first side of the antenna board 330 is configured to be folded so that it forms an angle with the first side of the main control board 310.

[0055] According to some embodiments of this application, the areas of the adapter board 320 and the antenna board 330 are smaller than the area of ​​the second power board 342 or the area of ​​the first power board 341, respectively, while the area of ​​the main control board 310 is larger than the area of ​​the second power board 342 or the first power board 341. The areas of the second power board 342, the first power board 341, the main control board 310, and the antenna board 330 are all larger than the areas of the second folding segment 331 and the third folding segment 340.

[0056] like Figure 11 As shown, according to some embodiments of this application, the first folding segment 321, the second folding segment 331 and the third folding segment 340 all include a flexible circuit board, the width of the second folding segment 331 is smaller than the width of the first folding segment 321, and the width of the first folding segment 321 is smaller than the width of the third folding segment 340.

[0057] See Figure 11 and Figure 12 As shown, where Figure 12 and Figure 11In the schematic diagram from the same perspective, the second folded segment 331 is connected to one side of the main control board 310, and the width of the second folded segment 331 is less than the length of the side it is connected to, so as to form a clearance gap 344 between the main control board 310 and the antenna board 330. Thus, as Figure 3 As shown, after the second folding section 331 is folded, there is still a clearance gap 344 between the antenna board 330 and the main control board 310, so that external components can pass through, thus avoiding interference between the antenna board 330 and external devices in the storage space 343.

[0058] See Figure 12 and Figure 13 As shown, according to some embodiments of this application, the main control board 310 has opposing first and second sides. A first folding segment 321 is connected to the first side, and a second folding segment 331 is connected to the second side. The width of the second folding segment 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 each other, that is, the clearance notch 344 is opposite to the first side where the adapter board 320 is located. Therefore, a portion of the structure of an external device connected to the first connection position 322 can pass through the clearance notch 344, avoiding interference with the antenna board 330.

[0059] like Figure 13 As shown, according to some embodiments of this application, the first folding segment 321 is strip-shaped. In the second state, the first folding segment 321 is folded, and the adapter plate 320 is located within the storage space 343. The adapter plate 320 at least partially overlaps with the main control board 310 in a first direction, wherein the first direction is along the height direction of the control board assembly 300 (e.g., ...). Figure 4 (Up and down direction). The adapter board 320 is opposite to and spaced apart from the main control board 310. At this time, the first connection position 322 faces the main control board 310 or is away from the main control board 310. In this way, when the first connection position 322 is connected to an external device, the external device can contact the main control board 310 to provide support, making the connection more stable. The portion of the structure of the external device that is spaced apart from the main control board 310 can be sandwiched between the adapter board 320 and the main control board 310. Figure 4 As shown, 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 connection position 322 is located on the side of the adapter board 320 facing the main control board 310.

[0060] See Figure 12As shown, according to some embodiments of this 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. Thus, after folding the first folding segment 321, the second folding segment 331, and the third folding segment 340, interference between any two of the adapter board 320 power board and the antenna board 330 can be avoided, as can interference between the adapter board 320 power board and the antenna board 330 themselves.

[0061] like Figure 10 and Figure 13 As shown, according to some embodiments of this 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 of the main control board 310, and the second power board 342 is connected to the other side of the main control board 310. In a second state, the first power board 341 and the second power board 342 are opposite to each other. In some embodiments, the main control board 310 is generally square, and there are two power boards, including the first power board 341 and the second power board 342. The first power board 341, the adapter board 320, the second power board 342, and the antenna board 330 are sequentially spaced along the circumferential direction of the main control board 310. The first power board 341 and the second power board 342 are opposite to each other. In a first state, the first power board 341 and the second power board 342 are located in the same plane. In a 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 sides of the main control board 310, and the first power supply board 341 and the second power supply board 342 are located on another pair of opposite sides of the main control board 310.

[0062] Power sub-components 3411 and 3421 are respectively provided on the first side of the first power board 341 and the first side of the second power board 342. Power sub-components 3411 and 3421 may include resistors, capacitors, inductors, switching transistors, or amplifiers, etc. No components are provided on the second side of the first power board 341 and the second side of the second power board 342. That is, the electronic components on the first power board 341 and the second power board 342 are located on the side of the power board facing the storage space 343, ensuring that the side with components faces the storage space 343, while the side without components faces the side wall of the housing 400, thereby reducing damage to electrical components during assembly. The first side of the first power board 341 and the first side of the second power board 342 are respectively configured to be folded to form an angle with the first side of the main control board 310, for example, perpendicular to each other or less than 90°. In some embodiments, a reinforcing plate is provided on one side of the first power board 341 away from the storage space 343, one side of the second power board 342 away from the storage space 343, and one side of the antenna board 330 away from the storage space 343, so as to support the first power board 341, the second power board 342 and the antenna board 330 and improve their structural strength.

[0063] like Figure 13 As shown, in the second state, the angles between the first power board 341, the second power board 342, and 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 a certain distance apart. 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 roughly cubic in shape. The electronic components on the main control board 310 are located on the side of the main control board 310 facing the storage space 343, the electronic components on the power boards are located on the side of the power boards facing the storage space 343, and the electronic components on the antenna board 330 can also be located on the side of the antenna board 330 facing the storage space 343 to protect the electronic components. In some embodiments, reinforcing plates are provided on one side of the first power board 341 away from the storage space 343, one side of the second power board 342 away from the storage space 343, and one side of the antenna board 330 away from the storage space 343, so as to support the first power board 341, the second power board 342 and the antenna board 330 and improve their structural strength.

[0064] See Figure 12 As shown, according to some embodiments of this application, the main control board 310 is provided with a power connection position 311, which is suitable for connection to a power source, which can be a battery. The power connection position 311 includes a positive connection point and a negative connection point, which are electrically connected to the corresponding electrical points of the power source. In the second state, the power connection position 311 is located on the side of the main control board 310 opposite to the storage space 343, which facilitates the connection of the control board assembly 300 to the power source and facilitates the corresponding connection of the positive and negative connection points to the electrical points of the power source.

[0065] See Figure 14 As shown, the near-eye display module 01 according to an embodiment of this application includes a display assembly 100 and a control board assembly 300 as described above.

[0066] Specifically, the control board assembly 300 is in the second state, and the display assembly 100 is located in the storage space 343. The display assembly 100 has a control board connection position, which is connected to the first connection position 322. The aforementioned external device is the display assembly 100. By folding the first folding segment 321, the second folding segment 331, and the third folding segment 340, the control board assembly 300 is folded as a whole, forming a structure with three-dimensional space, reducing its size in a single plane. At least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310, forming a storage space 343 for storing external devices. This avoids the adapter board 320, the power board, and the antenna board 330 being stacked in the thickness direction of the main control board 310, which would cause the overall thickness of the control board assembly 300 to be too large after being connected to the external device.

[0067] like Figure 14 As shown, the display assembly 100 has a first base 110 and a second base 120, which are connected by a fourth folding segment 113. The fourth folding segment 113 can be folded, allowing the first base 110 and the second base 120 to be stacked. When the display assembly 100 is connected to the control board assembly 300, the fourth folding segment 113 is folded. A microdisplay 111 is provided on the first base 110, and a control board connection position is provided on the second base 120, located on the side of the second base 120 facing the first base 110. An adapter plate 320 is disposed between the first base 110 and the second base 120. The side of the adapter plate 320 with a first connection position 322 faces the second base 120, and the first connection position 322 can be directly connected to the control board connection position. Thus, the first base 110, the adapter plate 320, and the second base 120 are configured in a stacked structure. Figure 6 and Figure 7 As shown, during assembly, the fourth folding segment 113 of the display assembly 100 protrudes from the first base 110 and the second base 120, and the fourth folding segment 113 is adapted to pass through the clearance notch 344.

[0068] In some embodiments, the near-eye display module 01 further includes a housing 400 and a storage component 200. The housing 400 has an installation space within which the display assembly 100, control board assembly 300, and storage component 200 are all located. The storage component 200 is connected to the display assembly 100 and is also housed within a storage space 343. Figure 4 and Figure 5 As shown, where Figure 4 and Figure 5 All are cross-sectional views of the near-eye display module 01. Figure 4 and Figure 5The corresponding cross-sections are perpendicular to each other. The storage component 200 has a second plate 220 and a first plate 210. The storage component 200 is L-shaped, with the second plate 220 embedded between the display component 100 and the main control board 310. The second plate 220 has a display connection position, and a storage connection position is provided on the side of the second plate facing away from the first plate. The storage connection position is connected to the display connection position. The second plate 220 and the main control board 310 may or may not be attached, as long as no electrical short circuit occurs. The first plate 210 is opposite to either the first power board 341 or the second power board 342; the two may or may not be attached, as long as no electrical short circuit occurs. In this way, a storage space 343 is constructed through the control board assembly 300. Both the display assembly 100 and the storage assembly 200 are housed within the storage space 343. The adapter plate 320 is flipped into the storage space 343 to connect with the display assembly 100, making full use of space and avoiding the excessive size of the near-eye display module 01 caused by arranging multiple components in a single direction. This facilitates the placement of the near-eye display module 01 on smart glasses, reduces interference from the near-eye display module 01 to the head, and improves wearing comfort. A light-transmitting portion 411 is provided at the top of the housing 400. The light-emitting surface 114 of the display assembly 100 faces the light-transmitting portion 411. An optical assembly 440 is provided between the light-transmitting portion 411 and the light-emitting surface 114. The optical assembly 440 is configured to receive light from the light-emitting surface 114 and allow the light to be reflected within it before being emitted. Figure 14 and Figure 5 As shown, the height of the display assembly 100 is less than the height of the power board, that is, the top surface of the microdisplay 111 does not protrude from the top of the power board, so as to facilitate the storage of other components. For example, part of the optical assembly 440 can be stored in the storage space 343. This allows the first plate 210 to be enlarged within the limited space inside the housing 400, providing sufficient mounting space for the memory chip 211, while avoiding the near-eye display module 01 from being too large in the height direction.

[0069] The display assembly 100 is disposed within the mounting space 401 and electrically connected to the control board assembly 300. The display assembly 100 is described in detail below.

[0070] See Figure 6 As shown, the display assembly 100 according to an embodiment of this application includes: a first base 110, a second base 120, a microdisplay 111, and a fourth folding segment 113.

[0071] Specifically, the microdisplay 111 is disposed on the first base 110, and the second base 120 is provided with a fourth connection position 121 and a second connection position 122. The fourth connection position 121 is located on one side of the second base 120, and the second connection position 122 is located on the opposite side of the second base 120. That is, the fourth connection position 121 and the second connection position 122 are respectively located on opposite sides of the second base 120. The microdisplay 111 is electrically connected to both the fourth connection position 121 and the second connection position 122. The fourth connection position 121 and the second connection position 122 are used for connecting the microdisplay 111 to other devices; for example, the fourth connection position 121 can be connected to a power supply device. Both the fourth connection position 121 and the second connection position 122 may include solder points and / or electrical sockets. Figure 6 As shown, the first base 110 and the second base 120 can be plate-shaped.

[0072] The fourth fold segment 113 connects the first base 110 and the second base 120. The fourth fold segment 113 may be provided with wires, or it may be a wire itself, to connect the microdisplay 111 and the fourth connection point 121, and to connect the microdisplay 111 and the second connection point 122. The fourth fold segment 113 is configured to allow folding, and the display assembly 100 is switchable between a first state and a second state. Figure 6 As shown, in the first state, the fourth folding segment 113 is unfolded, and the first base 110, the fourth folding segment 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 straight line. At this time, the first base 110 and the second base 120 are separated, and the display assembly 100 is unfolded, so that the micro display 111, the fourth connection position 121, and the second connection position 122 can be installed on the first base 110 or the second base 120.

[0073] like Figure 7 As shown, in the second state, the fourth folding segment 113 is folded, and the first base 110 and the second base 120 are stacked. With the fourth folding segment 113 folded, the display assembly 100 is generally cubic in shape for assembly. It should be noted that in the second state, when the fourth connection point 121 or the second connection point 122 is located on the side of the second base 120 facing the first base 110, the first base 110 and the second base 120 can be spaced a certain distance apart to allow external devices to connect to the fourth connection point 121 or the second connection point 122; when neither the fourth connection point 121 nor the second connection point 122 is located on the side of the second base 120 facing the first base 110, the first base 110 and the second base 120 can be spaced apart or fitted together. When the display assembly 100 is assembled into the near-eye display module, it is suitable to fold the fourth folding segment 113 to switch the display assembly 100 to the second state.

[0074] According to the display assembly 100 of this application, by setting a first base 110, the connection positions of the microdisplay 111 and the fourth connection position 121 are spaced apart. By setting a second base 120, the connection positions of the microdisplay 111 and the second connection position 122 are spaced apart. In the first state, the display assembly 100 is unfolded, which facilitates the welding and installation of the microdisplay 111, the fourth connection position 121, and the second connection position 122 during the manufacturing process. Furthermore, by folding the fourth folding segment 113, the display assembly 100 can be switched to the second state, where the fourth folding segment 113 is folded, and the first base 110 and the second base 120 are stacked. Separating the microdisplay 111 from the fourth connection position 121 and the second connection position 122 facilitates assembly, breaks the limitations of a single base structure, has higher space utilization, and allows for more flexible space arrangement, avoiding the inconvenience of assembly caused by excessive size in a single direction.

[0075] According to some embodiments of this application, the areas of the fourth connection position 121 and the second connection position 122 are both smaller than the areas of the first base 110 and the second base 120. That is, in the second state, the orthographic projections of the fourth connection position 121 and the second connection position 122 onto the plane of the first base 110 completely fall on the first base 110, and the fourth connection position 121 and the second connection position 122 do not protrude beyond the second base 120 in the circumferential direction. The area of ​​the fourth connection position 121 is greater than or equal to the area of ​​the second connection position 122. One of the fourth connection position 121 and the second connection position 122 is a memory chip soldering position, suitable for electrical connection with a memory chip; the other is a control board soldering position, suitable for connection with the main control board 310.

[0076] like Figure 20 As shown, the near-eye display module according to an embodiment of this application includes a housing 400, a main control board 310, a storage component 200, and a display component 100.

[0077] Specifically, the housing 400 has a mounting cavity, within which the main control board 310, storage component 200, and display component 100 are all housed. The housing 400 has a light-transmitting portion 411 facing the display component 100, through which the display component 100 projects a virtual image. The display component 100 is connected to both the main control board 310 and the storage component 200. The main control board 310 has a first display connection position 302 for connecting to the display component. The storage component 200 has a second display connection position 202, on which a storage chip is located, connected to the display component via the second display connection position 202. The display component 100 is in a second state, meaning it is connected to other components of the near-eye display module. The fourth connection position 121 is connected to the second display connection position 202, and the second connection position 122 is connected to the first display connection position 302. These connections can be soldered.

[0078] By separating the microdisplay 111 from the fourth connection position 121 and the second connection position 122, assembly is facilitated, breaking the limitation of the display assembly 100 adopting a single base structure. This results in higher space utilization and more flexible space arrangement, avoiding the display assembly 100 being too large in a single direction, which would cause the near-eye display module to be too bulky, and improving the user's comfort when wearing the near-eye display module.

[0079] like Figure 20 As shown, according to some embodiments of this application, the near-eye display module further includes an optical component 440. The optical component 440 is disposed within the mounting cavity and is located between the display component 100 and the light-transmitting portion 411. The optical axis of the microdisplay 111, the optical axis of the optical component 440, and the central axis of the light-transmitting portion 411 are on the same straight line. Furthermore, the optical component 440 is located on the side of the microdisplay 111 facing away from the first base 110. The optical component 440 is spaced apart from the microdisplay 111 and is configured to receive light from the microdisplay 111 and allow the light to be reflected within it before being emitted.

[0080] like Figure 21 As shown, according to some embodiments of this application, the storage component 200 includes a second board 220, a first board 210 and a storage chip 211 disposed on the first board 210. A second display connection bit 202 is disposed on the second board 220 and is electrically connected to the storage chip 211, thereby connecting the storage chip 211 and the microdisplay 111 through the second display connection bit 202 and the fourth connection bit 121.

[0081] The second plate 220 is connected to the first plate 210. The first plate 210 is configured to fold to a plane that is not parallel to the second plate 220, that is, after folding the fifth fold segment 212, the first plate 210 is set to be non-parallel to the second plate 220. The first plate 210 and the second plate 220 form an angle, and a storage space is formed between the second plate 220 and the first plate 210. The display assembly 100 is disposed in the storage space, and the display assembly 100 is stacked with the second plate 220. The second display connection position 202 can be disposed on the side of the second plate 220 facing the storage space. When the display assembly 100 is in the second state, the fourth connection position 121 is located on the side of the second base 120 away from the first base 110. When the display assembly 100 is stacked with the second plate 220, the fourth connection position 121 is attached to the second display connection position 202. The height of the microdisplay 111 is lower than the height of the first plate 210. That is, the light-emitting surface of the microdisplay 111 is located lower than the top of the first plate 210. Part of the optical component 440 can be stored in the storage space, reducing the size of the near-eye display module in the height direction.

[0082] According to some embodiments of this application, the second base 120 has two opposing sides, with the fourth connection position 121 located on one side and the second connection position 122 located on the other side. In a first state, the microdisplay 111 and the fourth connection position 121 are located on the same side of the display assembly 100, while the second connection position 122 is located on the other side. This eliminates the need for frequent flipping of the first base 110 and the second base 120 during the assembly of the microdisplay 111, the fourth connection position 121, and the second connection position 122, thus improving work efficiency. For example, see... Figure 6 As shown, both the first base 110 and the second base 120 can be plate-shaped. In the first state, the display assembly 100 is plate-shaped, and the first base 110 and the second base 120 are parallel or substantially parallel. The microdisplay 111 can be disposed with the first base 110 facing upwards (e.g., Figure 6 The fourth connection position 121 is located on the side of the second base 120 facing upwards, and the second connection position 122 is located on the side of the second base 120 facing downwards.

[0083] In the second state, the first base 110 and the second base 120 are spaced apart and configured to hold external devices. That is, a certain distance is maintained between the first base 110 and the second base 120 to allow external devices to be placed between them. The second connection point 122 faces the first base 110, and the fourth connection point 121 faces away from the first base 110. The first base 110 is located between the microdisplay 111 and the second base 120, with the microdisplay 111 located on the side of the first base 110 facing away from the second base 120. For example, an external device connected to the display assembly 100 can be placed between the first base 110 and the second base 120. In this case, the fourth connection point 121 or the second connection point 122 can be positioned on the side of the second base 120 facing the first base 110 for direct connection, reducing connecting parts and saving space. Figure 7 As shown, in the second state, the microdisplay 111 is away from the second base 120.

[0084] According to some embodiments of this application, the fourth fold segment 113 includes a flexible circuit board. In a first state, the fourth fold segment 113 is strip-shaped, parallel or substantially parallel to the first base 110, and the fourth fold segment 113 and the second base 120 are on the same straight line, thereby making the display assembly 100 flat. In a second state, the fourth fold segment 113 is connected to the same side of the first base 110 and the second base 120, and the fourth fold segment 113 is U-shaped.

[0085] like Figure 6 and Figure 7 As shown, according to some embodiments of this application, one end of the fourth folding segment 113 is connected to one side wall of the first base 110, and the other end is connected to one side wall of the second base 120. The width of the fourth folding segment 113 is smaller than the width of the first base 110 and smaller than the width of the second base 120, so as to reduce the space occupied by the fourth folding segment 113 and facilitate storage.

[0086] See Figure 7 and Figure 20 As shown, according to some embodiments of this application, the thickness of the first base 110 is L1, the gap between the first base 110 and the second base 120 is L2, and the length of the fourth folding segment 113 is greater than L1+L2, so that the fourth folding segment 113 has a sufficiently long length. In the second state, the distance between the first base 110 and the second base 120 can be adjusted within a large range, which is convenient for external devices to be placed between the first base 110 and the second base 120.

[0087] like Figure 7 and Figure 20As shown, in the second state, the fourth connection position 121 is located on the side of the second base 120 away from the first base 110, and the second connection position 122 is located on the side of the second base 120 facing the first base 110. The fourth connection position 121 is a control board soldering position, and the second connection position 122 is a chip soldering position. The part of the main control board 310 with the first display connection position 302 can be folded to be stored in the connection space.

[0088] like Figure 6 and Figure 20 As shown, the display assembly 100 also includes a first reinforcing piece 112, which is disposed on the side of the first base 110 opposite to the microdisplay 111, to support and protect the microdisplay 111. Figure 6 As shown, the first reinforcing sheet 112 is plate-shaped, and the area of ​​the side of the first reinforcing sheet 112 facing the microdisplay 111 is larger than the area of ​​one side of the microdisplay 111. The orthographic projection of the microdisplay 111 onto the plane where the first reinforcing sheet 112 is located falls on the first reinforcing sheet 112. In some embodiments, the first reinforcing sheet 112 may be bonded to the first base 110; or, the first reinforcing sheet 112 and the first base 110 may be integrally formed.

[0089] That is, the display assembly 100 includes a first base 110, a second base 120, and a microdisplay 111 disposed on the first base 110. The first base 110 and the second base 120 are connected, and there may be physical and electrical connections between the first base 110 and the second base 120. The microdisplay 111 may be any combination of technologies including, but not limited to, Micro-LED (Micro Light-Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing) or LBS (Laser Beam Scanning).

[0090] Storage component 200 is disposed within installation space 401 and electrically connected to display component 100. Storage component 200 is described in detail below.

[0091] See Figure 8 and Figure 9As shown, the storage component 200 according to an embodiment of this application includes a first board 210, a storage chip 211, a second board 220, and a fifth folded segment 212.

[0092] Specifically, the memory chip 211 is disposed on the first board 210, and the second board 220 is provided with a third connection position 221, which is connected to the memory chip 211 and is used to connect to external devices. In some embodiments, the third connection position 221 may include a plurality of spaced electrical contacts, which are arranged in an array along the length and width of the second board 220, and are configured to be detachably electrically connected to external devices.

[0093] The fifth folding segment 212 connects the first plate 210 and the second plate 220. The fifth folding segment 212 is bendable to allow the storage component 200 to switch between an unfolded state and a folded state. Figure 8 As shown, in the unfolded state, the first plate 210 and the second plate 220 are in the same plane, but separated to facilitate the soldering of the memory chip 211 and the third connection position 221 onto the first plate 210 or the second plate 220. Figure 8 As shown, in some embodiments, the first plate 210, the fifth folding segment 212, and the second plate 220 are connected in sequence. In the unfolded state, the first plate 210, the fifth folding segment 212, and the second plate 220 are on a straight line, and the storage component is in a straight line. When switching to the folded state, the first plate 210 is flipped relative to the second plate 220 by a certain angle.

[0094] like Figure 9 As shown, in the folded state, the fifth fold segment 212 is folded, and an angle is formed between the first plate 210 and the second plate 220. The memory chip 211 and the third connection position 221 are located in different planes to make full use of space and avoid making the size of the memory component 200 too large in a single direction. The first plate 210 and the second plate 220 define a storage space suitable for storing external devices. A storage angle A is formed between the first plate 210 and the second plate 220, where 0° < A < 180°. Figure 9 In the example, the storage angle A is 90 degrees. In this way, when the storage component 200 is connected to an external device, the external device is stored in the storage space and in contact with the second board 220. This shortens the connection distance between the external device and the third connection position 221, and the external device and the third connection position 221 can be directly connected, simplifying the connection lines.

[0095] According to the embodiments of this application, the storage component 200 has an unfolded state and a folded state by placing a storage chip 211 on a first plate 210 and a third connection position 221 on a second plate 220, with the storage chip 211 and the third connection position 221 spaced apart, and the fifth folding segment 212 being foldable. In the unfolded state, the first plate 210 and the second plate 220 are on the same plane, facilitating the installation of the storage chip 211 and the third connection position 221. In the folded state, a storage angle is formed between the first plate 210 and the second plate 220, and the two define a storage space for accommodating external devices. Thus, the storage chip 211 and the third connection position 221 are on different planes, making full use of space and avoiding excessive size of the storage component 200 in a single direction, thus preventing the near-eye display module 01 from becoming too large when the storage component 200 is applied to it.

[0096] According to some embodiments of this application, the first plate 210 and the second plate 220 respectively include a first surface and a second surface, wherein the first surface and the second surface are two opposite surfaces, such as... Figure 9 In the folded state, the first surface of the first plate 210 is configured to fold to form a storage angle A with the first surface of the second plate 220. The first surface of the second plate 220 is provided with a third connection position 221. The storage chip 211 is located on either the first surface or the second surface of the second plate 220. Figure 9 In the example, the memory chip 211 is disposed on the second surface of the second plate 220, and other devices can be accommodated between the first surface of the first plate 210 and the first surface of the second plate 220. The third connection position 221 is electrically connected to the memory chip 211 through the fifth fold segment 212.

[0097] According to some embodiments of this application, the fifth fold segment 212 is a flexible circuit board to connect the memory chip 211 and the fifth fold segment 212. The fifth fold segment 212 is strip-shaped, and the length of the fifth fold segment 212 (e.g., Figure 8 The fifth fold segment 212 (its dimension along the left-right direction) is smaller than the length of the first plate 210 and the length of the second plate 220. This prevents the folded fifth fold segment 212 from being too long, facilitating storage and minimizing space consumption. The width of the fifth fold segment 212 (perpendicular to its length) is less than or equal to the width of the first plate 210 and the width of the second plate 220. The fifth fold segment 212 does not protrude beyond the first plate 210 and the second plate 220, resulting in a neater overall shape for the storage component 200. In some embodiments, the area of ​​the fifth fold segment 212 is smaller than the area of ​​the first plate 210 and the area of ​​the second plate 220, while the area of ​​the first plate 210 is greater than or equal to the area of ​​the second plate 220.

[0098] According to some embodiments of this application, in the unfolded state, the memory chip 211 is located on the second side of the first plate 210, and the third connection bit 221 is located on the first side of the second plate 220. For example... Figure 8 As shown, the memory chip 211 is located with the first plate 210 facing upwards (e.g., Figure 8 On one side of the direction shown in the diagram, the third connection position 221 is located on the downward-facing side of the second plate 220. The memory chip 211 and the third connection position 221 are located on different sides. When the fifth folding segment 212 is folded, one of the memory chip 211 and the third connection position 221 is located inside the storage space, and the other is located outside the storage space. This avoids interference with external devices stored in the storage space due to both being located inside the storage space simultaneously. Figure 9 As shown, in some embodiments, in the folded state, the storage chip 211 is located on the side of the first plate 210 away from the storage space to avoid interference between the storage chip 211 and external devices in the storage space; the third connection position 221 is located in the storage space to shorten the distance with external devices in the storage space and facilitate connection, and the third connection position 221 can be directly connected to external devices.

[0099] According to some embodiments of this application, a reinforcing member is provided on the second plate 220. The reinforcing member may be plate-shaped. A third connecting position 221 is provided on one side of the second plate 220, and the reinforcing member is provided on the opposite side of the second plate 220. That is, the third connecting position 221 and the reinforcing member are provided on two opposite sides of the second plate 220. The reinforcing member can support and protect the third connecting position 221, and the reinforcing member can be bonded to the second plate 220. The area of ​​the side of the plate-shaped reinforcing member connected to the second plate 220 is greater than or equal to the area of ​​the side of the second plate 220 where the third connecting position 221 is provided. In some embodiments, the reinforcing member and the second plate 220 are integrally formed.

[0100] like Figure 18 As shown, the near-eye display module 01 according to an embodiment of this application includes a display assembly 100 and a storage assembly 200.

[0101] Specifically, the storage component 200 is in a folded state, and a storage space 343 is formed on the storage component 200. The display component 100 is connected to the storage component 200 to obtain image information from the storage component 200. The display component 100 is provided with a storage connection position, which is connected to a third connection position 221. The display component 100 is located in the storage space to facilitate connection with the third connection position 221. In this way, by switching the storage component 200 to a folded state and assembling it in the near-eye display module 01, the display component 100 is stored in the storage space. The third connection position 221 and the storage chip 211 are on different planes, making full use of the space of the storage component 200 for arrangement, and avoiding the storage component 200 being too large in one direction, which would cause the overall volume of the near-eye display module to be too large.

[0102] like Figure 9 and 19 As shown, when the storage angle is 90 degrees, the plane where the storage chip 211 is located is perpendicular to the plane where the third connection position 221 is located. The third connection position 221 is located within the storage space. The storage chip 211 is located on the side of the first plate 210 away from the storage space. The display assembly 100 is located within the storage space and connected to the third connection position 221 on the second plate 220. The thickness direction of the display is the same as the thickness direction of the second plate 220. The thickness directions of the storage chip 211 and the first plate 210 are perpendicular to the thickness direction of the second plate 220. This avoids the storage assembly 200 from being too large in a single direction after being connected to the display assembly 100, thus reducing the volume of the near-eye display module 01.

[0103] like Figure 19 As shown, the display assembly 100 is parallel or substantially parallel to the second plate 220, and the display assembly 100 and the second plate are stacked. A storage connection position is located on the side of the display assembly 100 facing the second plate 220. After the display assembly 100 is installed in the storage space, the storage connection position contacts and connects with the third connection position 221. The display assembly 100 is spaced apart from the first plate 210, and the light emission direction of the display assembly 100 is opposite to that of the second plate 220. Figure 18 and Figure 19 As shown, the display assembly 100 has a light-emitting surface 114, which is disposed away from the second plate 220.

[0104] like Figure 18 and Figure 19As shown, the near-eye display module 01 also includes a housing 400 and a main control board 310. The housing 400 has an installation space within which the main control board 310, the display assembly 100, and the storage assembly 200 are all housed. The housing 400 also has a light-transmitting portion 411, which faces the light-emitting surface 114 of the display assembly 100. An optical component 440 is positioned between the light-transmitting portion 411 and the display assembly 100. The optical component 440 is configured to receive light from the light-emitting surface 114 and allow the light to be reflected within it before exiting. The light emitted from the light-emitting surface 114 of the display assembly 100 projects a virtual image through the optical component 440 and the light-transmitting portion 411. The main control board 310 is connected to the display assembly 100, as shown... Figure 19 As shown, the main control board 310 can be folded and is roughly cubic in shape. The storage component 200 and the display component 100 can both be stored inside the main control board 310 to make full use of the installation space and reduce the size of the near-eye display module 01.

[0105] like Figure 18 and Figure 19 As shown, in some embodiments, the height of the display assembly 100 is less than the height of the first plate 210. That is, the light-emitting surface 114 of the display assembly 100 does not protrude from the first plate 210 in the height direction. Part of the optical assembly 440 can be located in the storage space. This allows the first plate 210 to be enlarged within the limited space inside the housing 400, providing sufficient mounting space for the memory chip 211, while avoiding the near-eye display module 01 from being too large in the height direction.

[0106] In storage component 200, the second plate 220 and the first plate 210 are connected. After folding the fifth folding segment 212, the first plate 210 is configured to be non-parallel to the second plate 220, and the storage component 200 is folded to form a folded storage component 200; the display component 100 is folded to form a folded display component 100; the shape of the folded storage component 200 is different from the shape of the folded display component 100. The storage component 200 can be foldable. It can be understood that the first plate 210 can be folded relative to the second plate 220, for example, the storage component 200 can be folded into an L-shape when viewed from the side, or the first plate 210 can be unfolded relative to the second plate 220, so that the first plate 210 and the second plate 220 are coplanar or approximately coplanar. The display module 100 can be foldable, for example, the display module 100 can be folded into a U-shape when viewed from the side. Alternatively, when the display module 100 is folded, the first base 110 and the second base 120 are parallel or substantially parallel; wherein the storage chip 211 may include random access memory (RAM) or read-only memory (ROM), such as flash memory, electrically erasable programmable read-only memory (EEPROM), wherein the storage chip 211 may store driver programs or image data that need to be displayed on the microdisplay 111, such as control programs that drive the microdisplay 111 to emit light or background maps of certain image frames, etc., thereby enabling the microdisplay 111 to achieve the expected image display in a short time. In other embodiments, the main control board may be provided with relevant light sensing or human-computer interaction sensors (such as inertial sensors, etc.), which can pre-store some preset sensing data. In other embodiments, it may also store certain basic data packets or communication data packets for subsequent firmware upgrades, which can be retrieved by the main control unit to improve working efficiency.

[0107] In this embodiment, when the first folding segment 321 is folded, the adapter plate 320 is configured to at least partially overlap with the main control board 310 in a first direction. The first direction can be the axial direction of the housing 400. It is understood that the size of the adapter plate 320 can be smaller than the main control board 310. The adapter plate 320 can be moved, flipped, or folded relative to the main control board 310 by folding the first folding segment 321, thereby forming a U-shaped structure when viewed from the side. In some embodiments, after folding the first folding segment 321, the adapter plate 320 can be fully projected onto the main control board 310 in the first direction, or after folding the first folding segment 321, a portion of the adapter plate 320 may be exposed or offset relative to the main control board 310, so that only a portion of the adapter plate 320 is projected onto the main control board 310 in the first direction. In some embodiments, after folding the first folding segment 321, the adapter plate 320 may also be arranged parallel or substantially parallel to the main control board 310. In some embodiments, the adapter plate 320 can be moved, flipped, or unfolded relative to the main control board 310 by unfolding the first folding segment 321, thereby making the adapter plate 320 and the main control board 310 coplanar or substantially coplanar. In other embodiments, the adapter plate 320 can also be kept in its folded state relative to the main control board 310, for example, by being fixed by an outer shell, snap-fit, adhesive, etc., or by curing with insulating adhesive or epoxy resin to maintain its folded state. It should be understood that the relevant folding descriptions mentioned later in this application can all be kept in the folded state after assembly.

[0108] The second base 120 is configured to at least partially overlap with the first base 110 in the first direction after the fourth fold segment 113 is folded. It is understood that the areas of the second base 120 and the first base 110 may be the same or approximately the same. After the second base 120 is moved, flipped or folded relative to the first base 110 by folding the fourth fold segment 113, the second base 120 may be fully projected onto the first base 110 in the first direction. Alternatively, after folding the fourth fold segment 113, the second base 120 and the first base 110 may 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 segment 113, the second base 120 and the first base 110 can be arranged parallel or substantially 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 segment 113, thereby forming a U-shaped structure when viewed from the side. The folding structure formed by moving, flipping, folding, or unfolding the fourth folding segment 113 relative to the first base 120 may be the same as or similar to the folding structure formed by moving, flipping, folding, or unfolding the first folding segment 321 relative to the adapter plate 320 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 segment 113, thereby causing the second base 120 and the first base 110 to unfold to the same plane, coplanar or substantially coplanar. In other embodiments, the second base 120 may also remain in a folded state relative to the first base 110; the second plate 220 is configured to be located between the main control board 310 and the second base 120, and electrically connects the memory chip 211 and the microdisplay 111; wherein the second plate 220 may be connected between the main control board 310 and the second base 120 by means such as electrical plug-in or soldering, the first base 110 and the second base 120 are configured to clamp the adapter plate 320 and electrically connect the microdisplay 111 to the main control board 310, the adapter plate 320 may be interconnected with the first base 110 by means such as electrical plug-in or soldering, and the light-emitting surface 114 of the microdisplay 111 is away from the adapter plate 320 in a 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 segment 321 is folded to move, flip, or fold the adapter plate 320 so that the adapter plate 320 overlaps with the main control board 310, and the first side of the adapter plate 320 faces the main control board 310; the first base 110 is moved, flipped, or folded relative to the second base 120 to ensure that the light-emitting surface 114 of the microdisplay 111 faces upward; and then the second plate 220 is inserted into the side of the second base away from the adapter plate 320. From the perspective of the final assembled form, along the light emission direction of the microdisplay 111 in the first direction, the main control board 310, the second board 220, the second base 120, the adapter board 320, the first base 110 and the microdisplay 111 are stacked in sequence. Since the control board assembly 300, the display assembly 100 and the storage assembly 200 can be designed and manufactured independently, the cost is lower than that of a single, larger circuit board.

[0110] In some application scenarios, for near-eye display modules with simple functions, the storage component 200 and the control board component 300 are generally folded and assembled on the same circuit board. However, as the functions increase, the thickness and width of the storage chip 211 of the storage component 200 also need to be increased accordingly. If simply folded, the height of the near-eye display module will be too high. Considering the near-eye display usage scenario of this application, if the near-eye display module is directly facing the human eye, its large thickness can easily cause a feeling of being poked by a foreign object. That is, if the near-eye display module is too thick and too close to the eye, it will cause discomfort to the human body. This application effectively reduces the thickness of the storage component 200 by moving, flipping, or folding the first plate 210 of the storage component 200, which has a large thickness, to the side of the main control board 310. The folding structure formed by moving, flipping, folding, or unfolding the adapter plate 320 in the control board component 300 relative to the first folding section 321 of the main control board 310, and the first base 110 in the display component 100, which is moved, flipped, folded, or unfolded, are also considered. The folding structure formed relative to the fourth folding segment 113 of the second base 120 is similar. However, the folding structure formed by moving, flipping, folding, or unfolding the first plate 210 in the storage assembly 200 relative to the fifth folding segment 212 of the second plate 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 segment 113 of the second base 120. Therefore, the respective structures can be fully utilized in space. The space created by the different structures formed after folding different components can be used to place components of other structures. Some electronic components can be placed in directions that are not the same as the arrangement directions of the control board assembly 300, the storage assembly 200, and the display assembly 100. This effectively avoids the near-eye display module 01 from being too large in a single direction after the three are connected, thus ensuring that the overall module size and volume are minimized.

[0111] In some embodiments, the first folding segment 321 may be part of the adapter plate 320. When the first folding segment 321 is part of the adapter plate 320, the adapter plate 320 is foldable, in which case folding or unfolding the first folding segment 321 is equivalent to folding or unfolding the adapter plate 320. In some embodiments, the first folding segment 321 may have a shorter length.

[0112] In some embodiments, the second folding segment 331 may be part of the antenna panel 330. When the second folding segment 331 is part of the antenna panel 330, the antenna panel 330 is foldable, and in this case, folding or unfolding the second folding segment 331 is equivalent to folding or unfolding the antenna panel 330. In some embodiments, the second folding segment 331 may have a shorter length.

[0113] In some embodiments, the third folding segment 340 may be part of the first power board 341 or part of the second power board 342. When the third folding segment 340 is part of the first power board 341, the first power board 341 is foldable, and in this case, folding or unfolding the third folding segment 340 is equivalent to folding or unfolding the first power board 341. When the third folding segment 340 is part of the second power board 342, the second power board 342 is foldable, and in this case, folding or unfolding the third folding segment 340 is equivalent to folding or unfolding the second power board 342. In some embodiments, the third folding segment 340 may have a shorter length.

[0114] In some embodiments, the fourth folding segment 113 may 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, and in this case, folding or unfolding the fourth folding segment 113 is equivalent to 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, and in this case, folding or unfolding the fourth folding segment 113 is equivalent to folding or unfolding the second base 120. In some embodiments, the fourth folding segment 113 may have a shorter length.

[0115] In some embodiments, the fifth folding segment 212 may be part of the first plate 210 or part of the second plate 220. When the fifth folding segment 212 is part of the first plate 210, the first plate 210 is foldable, and in this case, folding or unfolding the fifth folding segment 212 is equivalent to folding or unfolding the first plate 210. When the fifth folding segment 212 is part of the second plate 220, the second plate 220 is foldable, and in this case, folding or unfolding the fifth folding segment 212 is equivalent to folding or unfolding the second plate 220. In some embodiments, the fifth folding segment 212 may have a shorter length.

[0116] In some embodiments, in conjunction with reference to Figure 1-15The first power board 341 and the second power board 342 are equipped with power supply circuits, such as boost / buck circuits, voltage regulator circuits, drive circuits, etc. These circuits may further include corresponding microprocessor chips, resistors, capacitors, inductors, switching transistors, or amplifiers, etc. The first power board 341 and the second power board 342 are spaced apart and electrically connected to the main control board 310. After folding the third fold section 340, each of the first power board 341 and the second power board 342 is configured not 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 together enclose and form the storage space 343. Figure 15 As shown, the display assembly 100 and the storage assembly 200 are located in the storage space 343. The height of the microdisplay 111 is lower than the height of the storage space 343, and the microdisplay 111 does not protrude from the storage space 343. That is, in the folded assembly, the height of the microdisplay 111 is lower than the height of the first power board 341 and the second power board 342. The light from the microdisplay 111 is emitted from the storage space 343, thereby making full use of the internal space of the housing 400 and reducing the height dimension formed by the microdisplay 111, the first power board 341, and the second power board 342.

[0117] In some embodiments, in conjunction with reference to Figure 1-15 Antenna board 330 is connected to the side of main control board 310 and spaced apart from first power board 341 and second power board 342. Antenna board 330 is configured to be folded to a plane that is not parallel to main control board 310 and is different from first power board 341 and second power board 342. Antenna board 330 is electrically connected to main control board 310. The height of microdisplay 111 is lower than the height of antenna board 330. It can be understood that antenna board 330, first power board 341, second power board 342, and main control board 310 together form a receiver. The space 343 contains a first power board 341 and a second power board 342 that can be arranged opposite to or adjacent to each other. The antenna board 330 can be arranged adjacent to the first power board 341, or the antenna board 330 can be arranged adjacent to the second power board 342. The antenna board 330 is provided with an antenna 3301 and is configured to communicate with an external device. The external device can be a smartphone, computer, tablet, smart glasses, watch, etc. The near-eye display module 01 receives image content from the external device and displays it.

[0118] In some embodiments, the near-eye display module 01 also includes a battery 442. The battery 442 can be a rechargeable battery or a disposable battery, such as a button cell or a toroidal battery. The battery 442 is electrically connected to the main control board 310, the first power board 341, and the second power board 342 to power all electronic components. The battery 442 is located on the side of the main control board 310 opposite to the second board 220. The battery 442 is parallel or substantially parallel to the main control board 310, which reduces the radial size caused by combining with the power board, thus making full use of the housing space and ensuring the miniaturization of the near-eye display module.

[0119] In some embodiments, in conjunction with reference to Figure 1-15 The near-eye display module 01 also includes a first folding segment 321, a second folding segment 331, a third folding segment 340, a fourth folding segment 113, and a fifth folding segment 212. These segments can be folded or unfolded. Each folding segment can be formed by hinged connections between two electrical boards, or by using flexible wires or flexible printed circuit boards. Figure 10-15 For example, the adapter board 320 is connected to the main control board 310 via the first folding section 321, the antenna board 330 is connected to the main control board 310 via the second folding section 331, and the first power board and the second power board 342 are connected to the main control board 310 via 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 distributed circumferentially around the main control board 310 to effectively avoid interference between the adapter board 320, the power board, and the antenna board 330 in the folded state. Figure 10-12 After unfolding the second fold section 331, the third fold section 340, and the first fold section 321, 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. Electronic components on the antenna board 330 can also be located on the side of the antenna board 330 facing the storage space 343 to protect the electronic components.

[0120] The first base 110 is connected to the second base 120 via a fourth folded segment 113, and the first base 110 and the second base 120 can be plate-shaped. Figure 6 For example, the second base 120 is also configured to fold into the same plane as the first base 110, and the first base 110, the fourth folding segment 113, and the second base 120 can be arranged in a straight line. The first base 110 and the second base 120 can move relative to each other, allowing the display assembly 100 to be folded or unfolded for easy assembly. Figure 6As shown, in the third folded state, the first base 110, the fourth folding segment 113, and the second base 120 are connected sequentially and on the same straight line, making the display assembly 100 appear in a straight line. At this time, the first base 110 and the second base 120 separate, and the display assembly 100 unfolds, thus facilitating the mounting of the microdisplay 111, the fourth connecting position 121, and the second connecting position 122 on the first base 110 or the second base 120. The width of the fourth folding segment 113 is smaller than the width of the first base 110 and smaller than the width of the second base 120, in order to reduce the space occupied by the fourth folding segment 113 and facilitate storage.

[0121] See Figure 7 and Figure 14 As shown, according to some embodiments of this 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 segment 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 there is a connection space between the first base 110 and the second base 120. The connection space can accommodate other devices connected to the display assembly 100. At this time, the fourth connection position 121 or the second connection position 122 can be set on the side of the second base 120 facing the first base 110 to directly connect with the device, reducing the number of connecting parts and saving space.

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

[0123] According to the display assembly 100 of this application, the connection positions of the microdisplay 111 and the fourth connection position 121 and the second connection position 122 are independently separated by the first base 110 and the second base 120. In the third folded state, the display assembly 100 is unfolded, facilitating the welding and installation of the microdisplay 111 and the fourth connection position 121 and the second connection position 122 during the manufacturing process. Furthermore, the display assembly 100 can be switched to the third unfolded state by the fourth folding segment 113, in which the fourth folding segment 113 is folded and the first base 110 and the second base 120 are stacked. Separating the microdisplay 111 from the fourth connection position 121 and the second connection position 122 facilitates assembly, breaks the limitations of a single base structure, has higher space utilization, and allows for more flexible space arrangement, avoiding the inconvenience of assembly caused by excessive size in a single direction.

[0124] The second plate 220 is connected to the first plate 210 via the fifth folding segment 212, as follows: Figure 8 For example, after unfolding the fifth fold segment 212, the first plate 210 is also configured to be coplanar or substantially coplanar with the second plate 220, at which time the second plate 220, the fifth fold segment 212 and the first plate 210 can be in a straight line.

[0125] The first folding segment 321, the second folding segment 331, the third folding segment 340, the fourth folding segment 113, and the fifth folding segment 212 include a flexible circuit board. The flexible circuit board can be made of polyimide (PI) material as a substrate, and a conductive layer formed by etching metal (e.g., copper) is provided on the substrate. Of course, an insulating layer material can also be provided on it to prevent short circuits and enhance the stability of the circuit, or a protective layer of coating agent or anti-oxidation layer can be provided on the substrate to facilitate the folding segment being folded without being easily damaged.

[0126] In some embodiments, the main control board 310, antenna board 330, first power supply board 341, adapter board 320, and second power supply board 342 each include a first surface and a second surface, wherein the first surface and the second surface are two opposite surfaces, or two corresponding surfaces on the same board; for example Figure 10 The example is the first side, or the front side, such as... Figure 11 The example is the second side, or the reverse side.

[0127] The adapter board 320 has a first connection position 322 on its first surface and no components on its second surface. The first surface of the adapter board 320 is configured to fold up to face the first surface of the main control board 310. By placing the first connection position 322 on the adapter board 320, which is movable relative to the main control board 310, and stacking it with the display assembly 100, the adapter board 320 is located within the storage space 343, reducing the distance between the first connection position and the second connection position 122, thus facilitating connection. The position of the adapter board 320 can be flexibly changed by the first folding segment 321, which avoids the overall device being too large in a single direction and improves the compatibility of the control board assembly 300 with the installation environment. Furthermore, when soldering electronic components, the separation of the first connection position 322 and the main control board 310 provides more operating space and facilitates soldering. The first connection position 322 may include a soldering point or an electrical socket, or it may include both a soldering point and an electrical socket.

[0128] The first side of the main control board 310 is provided with a main control unit 3111 and a main control sub-component 3112. The main control unit 3111 and the main control sub-component 3112 are electrically connected to each other. The main control unit 3111 may include a chip with processing functions, and the main control sub-component 3112 may include resistors, capacitors, inductors, switching transistors or amplifiers, etc. The second side of the main control board 310 is provided with a power connection position 311, which is electrically connected to the battery 442. The power connection position 311 may include positive and negative connection points. For example, the same side of the battery 442 is provided with both positive and negative connection points. The power connection position 311 includes corresponding positive and negative connection points, and the two are in contact with each other to achieve electrical connection. In some embodiments, the power connection 311 includes a central polarity connection point and a plurality of peripheral electrical connection points, the plurality of peripheral electrical connection points being arranged around the central polarity connection point. The central polarity connection point can be either positive or negative, and the peripheral electrical connection points can be either positive or negative.

[0129] Antenna 3301 is located on the first or second side of antenna board 330. The first side of antenna board 330 is configured to be folded to form an angle with the first side of main control board 310, for example, perpendicular to each other or less than 90°. Antenna 3301 can be formed by printing, etching, injection molding, or sintering, or antenna 3301 can be electrically connected to antenna board by means of welding or other methods. Antenna board 330 is connected to main control board 310 via a second folding section 331, which is foldable to change the relative position of antenna board 330 and main control board 310. Power board is connected to main control board 310 via a third folding section 340, which is foldable to change the relative position of power board and main control board 310. Power board can regulate the current and voltage output of power supply to provide power to electronic components on control board assembly 300.

[0130] See Figure 11 and Figure 12 As shown, where Figure 12 and Figure 11 In the schematic diagram from the same perspective, the second folded segment 331 is connected to one side of the main control board 310, and the width of the second folded segment 331 is less than the length of the side it is connected to, so as to form a clearance gap 344 between the main control board 310 and the antenna board 330. Thus, as Figure 12 As shown, after the second folding section 331 is folded, there is still a clearance gap 344 between the antenna board 330 and the main control board 310 to allow external passage and prevent interference between the antenna board 330 and the display assembly 100.

[0131] See Figure 12 and Figure 13 As shown, according to some embodiments of this application, the main control board 310 has opposing first and second sides. A first folding segment 321 is connected to the first side, and a second folding segment 331 is connected to the second side. The width of the second folding segment 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 each other; that is, the clearance notch 344 is opposite to the first side where the adapter board 320 is located. Therefore, a portion of the structure of the display assembly 100 can pass through the clearance notch 344, avoiding interference with the antenna board 330.

[0132] The first connection point 322 is electrically connected to the main control unit and main control sub-components on the main control board 310 through the first folding section 321. The antenna is electrically connected to the main control unit and main control sub-components on the main control board 310 through the second folding section 331. The power supply sub-components are electrically connected to the main control unit and main control sub-components on the main control board 310 through the third folding section 340.

[0133] The control board assembly 300 has a first state and a second state. By unfolding or folding the first folding segment 321, the second folding segment 331, and the third folding segment 340, the relative positions of the main control board 310, the adapter board 320, the antenna board 330, and the power supply board are changed, thereby switching the control board assembly 300 between the first and second states. Figure 10 and Figure 11 As shown, in the first state, the first folding section 321, the second folding section 331, and the third folding section 340 are all unfolded, and the control board assembly 300 is fully unfolded. The adapter board 320, the power board, the antenna board 330, and the main control board 310 are all 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.

[0134] like Figure 13As shown, in the second state, the first folding segment 321, the second folding segment 331, and the third folding segment 340 are all folded, the control board assembly 300 is folded as a whole, the adapter board 320, the power board, and the antenna board 330 are all located on one side of the main control board 310, and at least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310 to form a storage space 343. In this way, switching the control board assembly 300 to the second state forms a structure with three-dimensional space, reducing its size in the plane where the main control board 310 is located; at least one of the adapter board 320, power board, and antenna board 330 has an angle greater than 0 degrees with the main control board 310, forming a storage space 343 for accommodating the display assembly 100 and storage assembly 200, avoiding the stacking of the adapter board 320, power board, and antenna board 330 in the thickness direction of the main control board 310, which would result in an excessively large overall thickness of the control board assembly 300 after connection with the display assembly 100 and storage assembly 200. It should be noted that the adapter board 320, power board, and antenna board 330 are all located on the same side of the main control board 310, that is, the adapter board 320, power board, and antenna board 330 are not in the same plane as the main control board 310, and the angle between the adapter board 320, power board, and antenna board 330 and the main control board 310 is less than 180 degrees. The above method can effectively avoid the excessive thickness of the control board assembly 300 after it is connected to the display assembly 100 and the storage due to the stacking of the adapter board 320, power board and antenna board 330 in the thickness direction of the main control board 310, thus optimizing the space layout.

[0135] In some embodiments, the first base 110 and the second base 120 each include a first surface and a second surface, which are two opposing surfaces. The first surface of the first base 110 is provided with a microdisplay 111, and the second surface of the first base 110 is provided with a reinforcing sheet. The first surface of the second base 120 is provided with a fourth connection position 121, and the second surface of the second base 120 is provided with a second connection position 122. The microdisplay 111 is electrically connected to the fourth connection position 121 and the second connection position 122 through a fourth folding segment 113. The first connection position 322 is configured to be electrically connected to the second connection position 122. The second surface of the second base 120 is configured to be folded so that it is opposite to the second surface of the first base 110. That is, corresponding connection positions are provided on both sides of the second base 120, thus ensuring that the microdisplay 111 is electrically connected to the main control board 310 and the memory chip respectively.

[0136] The first reinforcing piece 112 is disposed on the side of the first base 110 opposite to the microdisplay 111, to support and protect the microdisplay 111. Figure 6As shown, the first reinforcing sheet 112 is plate-shaped, and the area of ​​the side of the first reinforcing sheet 112 facing the microdisplay 111 is larger than the area of ​​one side of the microdisplay 111. The orthographic projection of the microdisplay 111 onto the plane where the first reinforcing sheet 112 is located falls on the first reinforcing sheet 112. In some embodiments, the first reinforcing sheet 112 may be bonded to the first base 110; or, the first reinforcing sheet 112 and the first base 110 may be integrally formed.

[0137] In some embodiments, the second plate 220 and the first plate 210 each include a first surface and a second surface, which are two opposing surfaces. The first surface of the first plate 210 is configured to be folded to form an angle with the first surface of the second plate 220, for example, perpendicular to each other or less than 90°. The first surface of the second plate 220 is provided with a third connection position 221. The memory chip 211 is located on the first surface or the second surface. The third connection position 221 is electrically connected to the memory chip 211 through a fifth folding segment 212. The storage component 200 can switch between an unfolded state and a folded state. The third connection position 221 is configured to be electrically connected to a fourth connection position 121, thereby electrically connecting the memory chip 211 and the microdisplay 111 via the second plate 220. Placing the third connection position 221 on the side of the second plate 220 facing the angled space can reduce the distance between the third connection position 221 and the fourth connection position 121, facilitating connection.

[0138] In the unfolded state, the first plate 210 and the second plate 220 are in the same plane, separated from each other to facilitate the soldering of the memory chip 211 and the third connection position 221 onto the first plate 210 or the second plate 220. Figure 8 As shown, in some embodiments, the first plate 210, the fifth folding segment 212, and the second plate 220 are connected sequentially. In the unfolded state, the first plate 210, the fifth folding segment 212, and the second plate 220 are in a straight line, and the storage component 200 is in a straight line shape. When switching to the folded state, the first plate 210 is rotated relative to the second plate 220 by a certain angle. Figure 9 As shown, in the folded state, the fifth fold segment 212 is folded, and an angle is formed between the first plate 210 and the second plate 220. The storage chip 211 and the third connection position 221 are located in different planes to make full use of space and avoid making the storage component 200 too large in a single direction. The first plate 210 and the second plate 220 define a storage space 343, which is suitable for storing the display component 100. A storage angle A is formed between the first plate 210 and the second plate 220, where 0° < A < 180°, such as 80°, 90°, or 100°, etc. Figure 9In the example, the storage angle A is 90 degrees. Thus, when the storage component 200 is connected to the display component 100, the display component 100 is stored in the storage space 343 and in contact with the second plate 220. This shortens the connection distance between the display component 100 and the third connection position 221, allowing the display component 100 and the third connection position 221 to be directly connected, simplifying the connection lines.

[0139] According to some embodiments of this application, in the unfolded state, the memory chip 211 is located on one side of the memory component 200, and the third connection bit 221 is located on the other side of the memory component 200. For example... Figure 8 As shown, the memory chip 211 is located with the first plate 210 facing upwards (e.g., Figure 8 On one side of the direction shown, the third connection position 221 is located on the downward-facing side of the second plate 220. The memory chip 211 and the third connection position 221 are located on different sides. When the fifth folding segment 212 is folded, one of the memory chip 211 and the third connection position 221 is located inside the storage space 343, and the other is located outside the storage space 343. This avoids interference between the two components located simultaneously inside the storage space 343 and the display assembly 100 stored within the storage space 343. Figure 9 As shown, in some embodiments, in the folded state, the storage chip 211 is located on the side of the first plate 210 away from the storage space 343 to avoid interference between the storage chip 211 and the display assembly 100 in the storage space 343; the third connection position 221 is located in the storage space 343 to shorten the distance with the display assembly 100 in the storage space 343 and facilitate connection. The third connection position 221 can be directly connected to the display assembly 100.

[0140] Of course, the storage chip 211 and the third connection position 221 can be located on the same side. For example, the storage chip 211 is located on the side facing the first board 210, and the third connection position 221 is located on the side facing the second board 220. When the fifth folding segment 212 is folded to switch to the folded state, depending on the folding direction, the storage chip 211 and the third connection position 221 can be located inside the storage space 343 or outside the storage space 343 at the same time. The specific location can be determined according to the installation environment of the storage component 200.

[0141] According to some embodiments of this application, a second reinforcing sheet is provided on the second plate 220. The second reinforcing sheet may be plate-shaped. A third connecting position 221 is provided on one side of the second plate 220, and the second reinforcing sheet is provided on the other side of the second plate 220 to support and protect the third connecting position 221. The second reinforcing sheet may be adhered to the second plate 220. The area of ​​the side of the plate-shaped second reinforcing sheet connected to the second plate 220 is greater than or equal to the area of ​​the side of the second plate 220 where the third connecting position 221 is provided. In some embodiments, the second reinforcing sheet and the second plate 220 are integrally formed.

[0142] The second plate 220 and the first plate 210 are located in different planes and are not parallel, defining an angled space between them. At this point, the thickness directions of the second plate 220 and the first plate 210 are different, thus preventing the storage component 200 from being too thick. The display component 100 is located within the angled space and is connected to both the control board assembly 300 and the storage component 200. In this way, by setting the control board assembly 300 and the storage component 200 as a structure of multiple connected plates, both of which can be folded to form a three-dimensional space, the installation space is fully utilized, and the size of the control board assembly 300 and the storage component 200 in any single direction is avoided from being too large. The storage component 200 is located within the storage space 343 of the control board assembly 300, and the display component 100 is located within the angled space of the storage component 200. The structure is compact and forms a relatively enclosed installation environment, providing protection against dust.

[0143] It should be understood that the first connection position 322, the second connection position 122, the third connection position 221 and the fourth connection position mentioned above can be electrical contacts, solder joints or mutually compatible electrical sockets or outlets, such as mutually compatible male and female electrical sockets.

[0144] In some embodiments, the areas of the adapter board 320 and the antenna board 330 are smaller than the area of ​​the second power board 342, meaning that no redundant electrical components are disposed on the adapter board. The areas of the main control board 310 and the first power board 341 are larger than the area of ​​the second power board 342. The first board body 210 is located between the first power board 341 and the second power board 342. The height of the microdisplay 111 is lower than the height of the first board body 210. The first power board 341 is also configured to fold so that it is parallel or substantially parallel to the second power board 342. That is, in the folded state, the first power board 341, the first board body 210, and the second power board 342 can be parallel or substantially parallel to each other. The first board body 210 can be located between the first power board 341 and the second power board 342, and the memory chip 211 can face either the first power board 341 or the second power board 342. See also Figure 10 and Figure 11As shown, according to some embodiments of this application, the adapter board 320 is connected to the main control board 310 via a first folding section 321, the antenna board 330 is connected to the main control board 310 via a second folding section 331, and the power board is connected to the main control board 310 via a third folding section 340. In the first folded state, the first folding section 321, the second folding section 331, and the third folding section 340 are all folded, and the adapter board 320, the power board, and the antenna board 330 are all located on one side of the main control board 310. At least one of the adapter board 320, the power board, and the antenna board 330 has an angle greater than 0 degrees with the main control board 310 to form a storage space 343.

[0145] In some embodiments, the near-eye display module 01 further includes an optical component 440, which is disposed within a housing space 343. The optical component 440 at least partially overlaps with the first power board 341 and the second power board 342 in a second direction, which is perpendicular to the first direction. That is, in the first direction (which may also be the axial or optical axis direction), the optical component 440 is at least partially housed in the housing space 343. In some embodiments, a light-transmitting portion 411 is provided on the housing 400. The light-transmitting portion 411 may be a solid light-transmitting area located in the housing 400, or it may be a through-hole structure located in the housing 400. Light from the optical component 440 is emitted through the through-hole. In this case, a light-transmitting protective cover may be additionally provided on the through-hole to protect the optical component 440. The optical component 440 is located between the display assembly 100 and the light-transmitting portion 411. The optical axis of the microdisplay 111, the optical axis of the optical component 440, and the central axis of the light-transmitting portion 411 are on the same straight line (optical axis). See also Figure 1 and Figure 4 As shown, where Figure 4 The dashed line with an arrowhead indicates the optical axis of the display assembly 100. For example... Figure 4 and Figure 5 As shown, in some embodiments, the top of the display assembly 100 is lower than the top of the storage space 343, and the end of the optical assembly 440 facing the display assembly 100 is located within the storage space 343. This increases the height of the perimeter walls of the storage space 343 within a limited space, that is, increases the height of the first power board 341 and the second power board 342, and increases the area of ​​the control board assembly 300 to accommodate more electronic components; at the same time, it makes the internal structure of the near-eye display module 01 more compact. In some embodiments, the optical assembly 440 can be implemented using the solution of Chinese application number 2023224964840.

[0146] In some embodiments, the housing 400 includes a cover 410, the cover 410 having a fixed step corresponding to the position of the light-transmitting portion 411, and the optical component 440 having a fixing block 441 on its side, the fixing block 441 abutting against the fixed step, and the microdisplay 111 and the optical component 440 having a gap in a first direction. Figure 1 and Figure 4 As shown, the light-transmitting part 411 is located in the non-central area of ​​the cover 410, and the central axis of the optical component 440 and the central axis of the main control board 310 are spaced apart from each other. Figure 7 As shown, after the second base 120 is configured to fold and at least partially overlap with the first base 110 in a first direction, the light-emitting surface 114 of the microdisplay 111 is offset from the center of the display assembly 100. The position of the light-transmitting portion 411 is located in the non-central region of the cover 410, and the central axis of the optical assembly 440 is spaced apart from the central axis of the main control board 310 to correspond to the light-emitting surface 114 of the microdisplay 111. In this way, the light output from the near-eye display module 01 is deviated from its central axis and is within a better field of view when mounted on the frame or lens. Of course, in some embodiments, the positions of the microdisplay 111, the light-transmitting portion 411, and the optical assembly 440 can also concentrate the light output from the near-eye display module 01 near the central axis.

[0147] like Figure 1 As shown Figure 2 As shown, the housing 400 includes a cover 410, a middle shell 420, and a base 430 connected in sequence, which together define an installation space. Figure 2 and Figure 3 As shown, the light-transmitting part 411 is provided on the cover 410, and the optical component 440 is connected to the cover 410. A plug-in plate 412 may be provided on the side of the cover 410 facing the installation space. The plug-in plate 412 extends along the thickness direction of the cover 410 and is arranged around the light-transmitting part 411.

[0148] In some embodiments, the optical component 440 is provided with a first fixing part, and the plug-in plate 412 is provided with a second fixing part. The first fixing part and the second fixing part are connected to fix the optical component 440. One of the first fixing part and the second fixing part can be a protrusion, and the other can be a groove. For example, Figure 1 As shown, the optical component 440 is cylindrical and has at least one fixing block 441 on its outer surface. The inner wall of the plug plate 412 is provided with a fixing groove, and the fixing block 441 is embedded in the fixing groove to fix the optical component 440.

[0149] like Figure 1As shown, according to some embodiments of this application, the middle shell 420 is provided with a locking groove 421, which has a moving section and a limiting section. The moving section extends along the axial direction of the middle shell 420, and the limiting section extends along the circumferential direction of the middle shell 420. A locking block 431 is provided on the base 430. During installation, the moving section is aligned with the locking block 431, and the locking block 431 moves through the moving section into the limiting section, rotating the middle shell 420 relative to the base 430, thereby limiting the relative movement of the middle shell 420 and the base 430 in the axial direction. The dimensions of the near-eye display module 01 are such that the radial diameter 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, or 7 mm. Height less than or equal to 18mm, such as 18mm, 17mm, 16mm, 15mm, 14mm, 13mm, 12mm, 11mm, 10mm, 9mm, 8mm, 7mm.

[0150] In some embodiments, housing 400 further includes a middle housing 420 and a base 430, the middle housing 420 having a locking groove 421 and the base 430 having a locking block 431, the battery 442 being located between the middle housing 420 and the base 430, the locking block 431 being configured to be releasably engaged with the locking groove 421, wherein one or more mechanisms of various kinds may be provided to secure and release components from each other. For example, mechanisms such as locks, latches, snaps, sliders, channels, screws, snap rings, threads, magnets, pins, interference (e.g., friction) fits, rolling mills, snap pins, fused materials, fabrics, knitted fabrics, braided fabrics, hook and loop fasteners and / or combinations thereof may be included.

[0151] In some embodiments, the near-eye display module further includes a second magnetic chuck 522 located between the battery 442 and the base 430. The second magnetic chuck 522 can be, for example, glued or snapped onto the base 430. The second magnetic chuck 522 is configured to attract external magnetic chucks. The second magnetic chuck 522 can be flat and can be a magnet capable of attracting each other. In other embodiments, the second magnetic chuck 522 can also be a metal sheet capable of being attracted by a magnet.

[0152] See Figure 16As shown, this application also provides a near-eye display device 02, which can be AR glasses, VR glasses, or nearsighted glasses, etc. The device includes a frame 500, a lens 510 disposed on the frame 500, and a near-eye display module 01 as described above. In some embodiments, the near-eye display module 01 is connected to the frame 500, and the near-eye display module 01 can be located on a side of the frame 500 near or facing the human eye, with the light-transmitting portion 411 of the near-eye display module 01 facing the lens 510; or, the light-transmitting portion 411 of the near-eye display module 01 can also be directly facing the human eye. The near-eye display module 01 can be fixed to the frame 500 and / or the lens by a clamping member; or, as... Figure 17 As shown, the near-eye display module 01 can be fixed to the frame 500 and / or lens 510 by the first magnetic chuck 520. The base 430 of the near-eye display module 01 is configured to be attracted by the first magnetic chuck 520. In other embodiments, for example, a magnetic element that magnetically attracts the first magnetic chuck 520 can be provided on the side of the near-eye display module 01 opposite to the optical module. For example, the first magnetic chuck and the magnetic element can be mutually magnetic magnets, i.e., the near-eye display module 01 is fixed to the lens by the mutual attraction of the two magnets, such as the lens of glasses or a helmet. The frame 500 or lens 510 can include myopia glasses, hyperopia glasses, sunglasses, AR, VR, or smart glasses, or goggles, or safety helmets, cycling helmets, or smart helmets, etc. By configuring the control board assembly 300 and storage assembly 200 as a structure of multiple connected panels, both of which can be folded to form a three-dimensional space, the installation space is fully utilized, avoiding excessive size of the control board assembly 300 and storage assembly 200 in any single direction. This results in a more reasonable and compact overall structural layout for the near-eye display module 01. When using the near-eye display device 02, the discomfort caused to the eyes by an excessively large near-eye display module 01 can be reduced. Furthermore, the small size design allows the near-eye display module to be concealed from the outside, without interfering with the normal field of vision. The smaller overall size and weight also improve comfort. In addition, the small size of the near-eye display module 01, when applied to the aforementioned head-mounted device, allows for convenient and detachable fixing to any position, achieving compatibility and intelligent expansion with traditional head-mounted near-eye devices.

[0153] The near-eye display module provided in this application sets the control board assembly, display assembly, and storage assembly into multiple independent structures and then assembles and connects them. Each structure can be folded to form a corresponding structure and space. By making full use of the folded structure and space for assembly, the size of the control board assembly, display assembly, and storage assembly in a single direction is effectively reduced. This avoids the overall assembly size being too large due to excessive size in a single direction, thereby ensuring that the overall structural assembly layout of the near-eye display module is reasonable and the structure is more compact. This helps to reduce costs and improve assembly efficiency. In addition, the small size of the near-eye display module effectively improves the portability and mobility of the product, greatly expanding the application scenarios.

[0154] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
