[0038] Current extended reality devices such as augmented reality (AR) glasses need to have wireless communication capabilities in addition to providing enhanced display in order to exchange data with other devices. AR glasses generally design antennas on the upward side of the temples, and place the circuit board and various components inside the temples. However, this structural design has the following problems:

[0039] Electromagnetic interference problem: The internal space of the temples is limited, and the circuit board and the electronic components on it will cause electromagnetic interference to the antenna, thereby affecting the antenna's gain and efficiency, resulting in a decrease in signal performance.

[0040] Reduced gain efficiency: Since the layout of the circuit board is limited by the narrow space of the temple, the design flexibility of the antenna is limited and the optimal gain effect of the antenna cannot be guaranteed.

[0041] Signal quality degradation: Glasses are usually equipped with human-machine interaction methods, such as touch areas for touch interaction. When touching, human skin may cause a short circuit at the connection between the two antennas, causing the frequency characteristics of the antenna to shift, resulting in signal quality degradation. The shift in frequency characteristics may affect the matching performance of the antenna, further reducing the stability and reliability of communication.

[0042] The embodiment of the present application provides an optical waveguide component and an augmented reality device, which may be smart glasses such as AR glasses, VR glasses or MR glasses, to solve the problem that the communication performance of existing augmented reality devices is poor and affects the user experience. Figure 1-5 Provide explanation.

[0043] In one aspect of the present application, an optical waveguide assembly is provided for an augmented reality device, wherein the augmented reality device comprises a frame, and the optical waveguide assembly is mounted on the frame. Figure 1 and Figure 2 As shown, the optical waveguide component includes an optical waveguide substrate 100 , a cover plate 200 , and an antenna 300 . The cover plate 200 is connected to the optical waveguide substrate 100 , and the antenna 300 is disposed on the optical waveguide substrate 100 and / or the cover plate 200 .

[0044] By installing the antenna 300 of the augmented reality device on the optical waveguide substrate 100 or the cover plate 200 of the optical waveguide assembly on the frame, and setting it away from the circuit main board and other electronic components in the temple, the electromagnetic interference from the circuit main board and other electronic components is reduced to ensure the stability of communication signal transmission, improve the signal gain of the augmented reality device and the efficiency of the antenna 300, optimize the communication performance, and improve the user experience.

[0045] It can be understood that in this embodiment, the optical waveguide component is used to project the display content to the human eye, and the optical waveguide substrate 100 can be made of a transparent material (such as glass or plastic) and has light-guiding properties. The optical waveguide substrate 100 can be provided with an in-coupling grating 110 and an out-coupling grating 120, and guides the light through the principle of total internal reflection. The optical waveguide substrate 100 can be a type such as a geometric array optical waveguide or a surface relief optical waveguide to ensure that the light is efficiently propagated within the substrate. The cover plate 200 is connected to the optical waveguide substrate 100 to form a closed structure to protect the internal optical path from damage by dust and other impurities. The cover plate 200 is also usually transparent to maintain the brightness of the real environment observed by the human eye through the optical waveguide component, that is, the external light can enter the human eye at a higher transmittance.

[0046] The antenna 300 can be a special shape line formed by depositing conductive material (such as copper) on a flexible circuit board, that is, an FPC antenna. The FPC antenna can be bent and is suitable for product designs with complex or irregular shapes. It is relatively light and thin, easy to integrate, and will not increase the size and weight of the device. It can also be a line deposited on the inner surface of the glass cover 200, that is, an LDS antenna. It can be designed according to actual needs, and this embodiment does not specifically limit this.

[0047] In an alternative embodiment, reference Figure 3 As shown, a hollow cavity 201 is formed inside the cover plate 200 , and the antenna 300 is disposed in the hollow cavity 201 .

[0048] It is understandable that the cover plate 200 may be a hollow structure, with a hollow cavity 201 disposed therein for accommodating the antenna 300. The hollow cavity 201 provides a closed space for the antenna 300, which can effectively isolate the antenna 300 from the external environment and reduce the impact of dust, moisture and other harmful factors on the antenna 300. The design of the hollow cavity 201 allows a certain amount of spatial isolation between the antenna 300 and the circuit board and other electronic components, which helps to reduce the electromagnetic interference of the circuit board and other electronic components to the antenna 300.

[0049] Furthermore, the design of the hollow cavity 201 does not affect the appearance of the augmented reality device, while allowing a more compact internal component layout, which helps to reduce the weight and volume of the device. In some optional embodiments, the hollow cavity 201 can also serve as a heat dissipation channel to help the antenna 300 and internal electronic components to better dissipate heat, thereby extending the service life of the augmented reality device.

[0050] In an optional embodiment, the number of the cover plate 200 is one, and the cover plate 200 is connected to a side of the optical waveguide substrate 100 where the gratings (the coupling-in grating 110 and the coupling-out grating 120) are provided to protect the gratings.

[0051] In another alternative embodiment, referring to Figure 2 As shown, there are two cover plates 200, that is, the cover plate 200 includes a first cover plate 210 and a second cover plate 220, and the first cover plate 210 and the second cover plate 220 are respectively connected to the two sides of the optical waveguide substrate 100 to fully protect the optical waveguide substrate 100 and the grating.

[0052] Exemplarily, during connection, glue is first applied around the first cover plate 210 and the second cover plate 220, and then the optical waveguide substrate 100 is aligned and connected with the first cover plate 210 and the second cover plate 220 on both sides, and the bonding is completed after the glue is cured; specifically, the optical waveguide substrate 100 and the cover plates 200 on both sides can be glued with various organic transparent materials such as UV glue, thermosetting glue, PVB glue, etc., or connected with transparent tapes such as OCA optical glue; due to the high viscosity of the glue, even if the cover plate 200 is broken by a great external force, the fragments of the cover plate 200 will be tightly adhered to the optical waveguide substrate 100, and will not splash around, thereby protecting the safety of the user.

[0053] It can be understood that both the first cover plate 210 and the second cover plate 220 can be used to install the antenna 300 .

[0054] In an alternative embodiment, reference Figure 1 and Figure 4 As shown, the first cover plate 210 is located on the near-eye side (i.e., the side close to the user's eyes) of the optical waveguide substrate 100, the second cover plate 220 is located on the back-eye side (i.e., the side close to the user's eyes) of the optical waveguide substrate 100, and the antenna 300 is arranged on the second cover plate 220.

[0055] In this embodiment, by setting the antenna 300 on the second cover plate 220 on the side away from the human eye, it can be as far away from the user's head as possible, reducing the impact of electromagnetic radiation on the user, improving the safety of the device, and as far away from the circuit board and electronic components as possible, reducing electromagnetic interference, and facilitating the transmission and reception of the antenna 300. It can also avoid mutual interference between the antenna 300 and the optical waveguide substrate 100 and the near-eye optical element, and the light of the optical waveguide component will not encounter the obstruction of the antenna 300 during the propagation process, ensuring that the image quality is not affected.

[0056] Furthermore, disposing the antenna 300 on the outer second cover plate 220 also facilitates maintenance and upgrading of the antenna 300 without disassembling the entire optical waveguide assembly.

[0057] In an alternative implementation, reference Figure 1 As shown, the second cover plate 220 includes a first inner surface 221 and a second inner surface 222 that are oppositely disposed. The first inner surface 221 is located on a side of the second inner surface 222 away from the optical waveguide substrate 100 , and the antenna 300 is disposed on the first inner surface 221 .

[0058] It should be noted that the antenna 300 may be disposed on both inner surfaces of the first cover plate 210 and the second cover plate 220 .

[0059] In this embodiment, in order to further optimize the performance and effect of the antenna 300 and not affect the optical effect of the optical waveguide component, the antenna 300 is arranged on the first inner surface 221 of the second cover plate 220 away from the human eye side and away from the optical waveguide substrate 100. Since the antenna 300 is located on the first inner surface 221 and away from the optical waveguide substrate 100, the potential interference of the electromagnetic field on the optical path of the optical waveguide is reduced, thereby improving the image quality and user experience. The antenna 300 is arranged inside the second cover plate 220, which can effectively prevent physical damage and environmental factors (such as humidity and dust), and helps to integrate more functional components while keeping the overall structure of the augmented reality device compact.

[0060] In an alternative embodiment, reference Figure 2 As shown, a first gap 101 is defined between the first cover plate 210 and the optical waveguide substrate 100 , a second gap 102 is defined between the second cover plate 220 and the optical waveguide substrate 100 , and the antenna 300 is disposed in the first gap 101 and / or the second gap 102 .

[0061] In this embodiment, the first cover plate 210 and the second cover plate 220 can be solid structures. When the first cover plate 210 and the second cover plate 220 are connected to the optical waveguide substrate 100, a first gap 101 and a second gap 102 are formed. The first gap 101 and the second gap 102 can be used to arrange the antenna 300, which facilitates the arrangement and installation of the antenna 300.

[0062] Optionally, the antenna 300 may be disposed in the second gap 102, on the one hand to keep it as far away from human eyes as possible, and on the other hand to avoid interfering with the optical path propagation of the optical waveguide component.

[0063] Furthermore, the optical waveguide component also includes a coupling-in grating 110 and a coupling-out grating 120. The coupling-in grating 110 and the coupling-out grating 120 can be arranged on the surface of the optical waveguide substrate 100 and located in the first gap 101 or the second gap 102. The gap can protect the grating and provide a refractive difference space for light path propagation to ensure imaging quality.

[0064] The function of the coupling-in grating 110 is to effectively couple the light signal from the micro-projection optical module into the optical waveguide substrate 100 so as to propagate in the optical waveguide substrate 100. The function of the coupling-out grating 120 is to couple out the light signal propagating in the optical waveguide substrate 100 and guide it to the user's eyes to form a visible augmented reality image.

[0065] In an alternative embodiment, reference Figure 4 As shown, the antenna 300 may be disposed on a surface of the second cover plate 220 and located on a side close to the optical waveguide substrate 100 .

[0066] In an optional manner, the antenna 300 may also be formed on the outer surface of the optical waveguide substrate 100 or inside the optical waveguide substrate 100 to improve the compactness and stability of the overall design.

[0067] In an alternative embodiment, reference Figure 5 As shown, there are multiple antennas 300 , and isolation sheets are provided between the multiple antennas 300 .

[0068] In this embodiment, in order to improve the reliability, coverage and performance of wireless communication, the augmented reality device can be configured with multiple antennas 300 of different types, and the multiple antennas 300 can be installed on different cover plates 200 or on the same cover plate 200. When multiple antennas 300 are installed on the same cover plate 200, in order to avoid mutual interference between the antennas 300, an isolation sheet can be set between two adjacent antennas 300 to separate them. The isolation sheet can be a conductive or non-conductive material, and its function is to physically or electromagnetically isolate the antennas 300 to prevent coupling effects between them.

[0069] In an optional embodiment, the optical waveguide component further includes a feeding port, which is used to connect to the circuit board, and the multiple antennas 300 are connected to the same feeding port.

[0070] Exemplarily, the feeding port can be set on the side close to the connection between the optical waveguide component and the frame, so as to realize the effective connection between the antenna 300 and the circuit board. During the normal use of the augmented reality device, the antenna 300 is connected to the circuit through the feeding port to receive and send signals, so that the augmented reality device can communicate wirelessly with other mobile terminals.

[0071] Furthermore, when multiple antennas 300 are configured, the multiple antennas 300 are not independently connected to the circuit board, but are connected to the circuit board through the same feeding port, thereby simplifying the circuit layout, reducing connection points and space occupancy, making the overall structure more compact, reducing manufacturing costs and complexity, and facilitating maintenance.

[0072] In an optional implementation, the refractive index of the antenna 300 is 1.4-1.6. For example, the refractive index of the antenna 300 may be 1.4, 1.45, 1.5, 1.55 or 1.6.

[0073] In this embodiment, the antenna 300 may be made of a transparent conductive material with a low refractive index, such as PEDOT / PSS (poly 3,4-ethylenedioxythiophene / polystyrene sulfonate), whose refractive index is in the range of 1.4-1.6, close to the refractive index of glass (about 1.5), thereby ensuring that after the antenna 300 is arranged in the optical waveguide substrate 100, the total reflection condition of the optical waveguide will not be destroyed.

[0074] Since the refractive index of the antenna 300 material is lower than that of the optical waveguide substrate 100, the light can continue to be fully reflected in the optical waveguide substrate 100, thereby effectively transmitting the image signal to the user's eyes. The antenna 300 made of transparent conductive material will not significantly affect the light transmittance of the optical waveguide, so that the user's real environment vision will not become blurred or dim due to the presence of the antenna 300.

[0075] The circuit board can also use transparent materials within the scope of the optical waveguide component, such as ITO (indium tin oxide), silver nanowires or graphene sheets. These materials are also highly transparent and conductive and will not have a negative impact on the transmittance of the optical waveguide.

[0076] The optical waveguide assembly provided in the embodiment of the present application includes an optical waveguide substrate 100, a cover plate 200 and an antenna 300. The cover plate 200 is connected to the optical waveguide substrate 100, and the antenna 300 is arranged on the optical waveguide substrate 100 and / or the cover plate 200. By installing the antenna 300 of the augmented reality device on the optical waveguide substrate 100 or the cover plate 200 of the optical waveguide assembly on the frame, and setting it away from the circuit main board and other electronic components in the temple, the electromagnetic interference from the circuit main board and other electronic components is reduced to ensure the stability of the communication signal transmission, improve the signal gain of the augmented reality device and the efficiency of the antenna 300, optimize the communication performance, and improve the user experience.

[0077] An embodiment of the second aspect of the present application provides an augmented reality device, which includes a frame, an optical waveguide component of the above embodiment, and a circuit board. The optical waveguide component is installed on the frame, and the circuit board is provided with a spring clip, which is used to connect to the feeding port of the optical waveguide component.

[0078] Exemplarily, the circuit board is a flexible circuit board, i.e., an FPC circuit board; the FPC circuit board is provided with a spring at the connection between the corresponding optical waveguide component and the frame, the spring can be provided at a position on the FPC circuit board close to the light coupling region of the optical waveguide, and the spring contacts the feed port of the antenna 300 in the glass cover plate 200 of the optical waveguide component; the feed port of the antenna 300 can be provided at the end surface of the glass cover plate 200 close to the frame. The circuit board is provided with a main board at the position corresponding to the temple, and the main board has a control chip for the antenna 300.

[0079] The use of FPC circuit boards improves the flexibility of circuit layout, and the design of the spring clip simplifies the connection process between the circuit board and the feed port of the antenna 300, reducing the difficulty of assembly. The connection method of the spring clip provides a stable electrical connection between the circuit board and the antenna 300, reducing communication failures caused by poor connection.

[0080] Furthermore, the augmented reality device may also include a micro display screen and electronic components such as a processor, memory, sensors, and batteries, etc., for realizing display and corresponding functions.

[0081] The extended reality device of this embodiment integrates the antenna 300 on the optical waveguide component, reducing the impact of electromagnetic interference on the antenna 300, so that the antenna 300 can maintain a high signal gain and transmission efficiency in the extended reality device. The antenna 300 is placed on the glass cover plate 200 on the side of the optical waveguide component away from the human eye, away from the circuit board and components in the temple, and the structure of the glass cover plate 200 is used to avoid electromagnetic interference. The embedded design makes the extended reality device more beautiful and lightweight, and provides a more stable communication connection. And moving the antenna 300 out of the temple allows the motherboard space in the temple to better accommodate other electronic components, optimizing the layout of components.

[0082] It can be understood that if the optical waveguide component has the beneficial effects of the above embodiments, then the augmented reality device also has the beneficial effects of the above embodiments accordingly. The specific implementation method can refer to the above embodiments, which will not be elaborated in this embodiment.

[0083] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0084] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the protection scope of the present application.
