Description

Technical Field

[0001] The present disclosure relates to the technical field of wireless communications, and more particularly to a lens assembly and a wireless electronic device including the lens assembly. Background Art

[0002] Recent years have witnessed a boom in electronic wearable devices. These devices are designed so that they typically do not need to be held during use, but are instead "worn" on the user's (i.e., wearer's) body as accessories or even clothing. This makes it very convenient for the wearer to interact with the external world in multiple ways simultaneously. For example, virtual reality (VR) or augmented reality (AR) technologies can utilize electronic head-mounted devices to provide visual and / or auditory information, while the wearer can manually operate a keyboard or game controller. As another example, electronic bracelets can collect the wearer's electrocardiogram (ECG) signals without interfering with the wearer's daily activities. As yet another example, electronic glasses can provide the wearer with the details of instant messages even when the wearer's hands are occupied. Because visual signals are the most common type of information received by humans, many electronic wearable devices are head-mounted and adapt to the user's vision to facilitate interaction with the user's eyes.

[0003] Rapid advances in batteries and integrated circuits have enabled electronic wearable devices to achieve smaller sizes and more compact structures, aiming to integrate these devices into a variety of applications in people's daily lives. Consequently, the growing demand for convenient "anytime, anywhere" access to the internet and wireless local area networks (WLANs) requires electronic wearable devices to be wireless and portable. The future envisions electronic wearable devices capable of providing high-quality wireless access while not impacting the electromagnetic environment of other components in the device. For example, AR / VR head-mounted displays are expected to be no larger or heavier than standard glasses or goggles. This goal poses a significant challenge to the robust design of electronic wearable devices, especially wireless ones. Summary of the Invention

[0044] Hereinafter, the technical solutions in the embodiments of the present disclosure will be described in conjunction with the accompanying drawings in the embodiments of the present disclosure. The described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Any other embodiments obtained based on the embodiments of the present disclosure by those skilled in the art without any creative work shall fall within the scope of protection of the present disclosure.

[0045] Relational terms such as "first", "second", etc. are used herein only to distinguish one entity or operation from another entity or operation, and do not require or imply the existence of an actual relationship or order between the entities or operations. In addition, terms such as "include", "comprises", or any other variations thereof are meant to be non-exclusive. Thus, a process, method, article, or apparatus that includes a series of elements includes not only the disclosed elements, but also other elements that are not clearly listed, or inherent elements of the process, method, article, or apparatus. Unless expressly limited, the statement "includes..." does not exclude the possibility that other similar elements may exist in the process, method, article, or apparatus in addition to the listed elements.

[0046] As described in the background, the demand for wireless and portable electronic wearable devices requires compact designs for components within the devices. This demand is particularly stringent for head-mounted electronic devices, as bulky and heavy head-mounted devices are not only inconvenient during use but also pose health risks, particularly exacerbating neck pain. Therefore, many wireless wearable electronic devices attempt to place each component as close to the user's body as possible to minimize the discomfort caused by the imbalance of additional weight while walking, jogging, or simply moving. On the one hand, this design can increase interference between the antenna and other components, thereby reducing the quality of wireless communication. This degradation is further exacerbated when the electronic device's housing is made of conductive materials (such as metal), as the conductive material creates an electromagnetic shielding effect. In this case, the housing must have non-conductive portions to provide a "window" for wireless signals to pass through, which increases manufacturing complexity. On the other hand, this design places the antenna very close to the user's body. For example, the antenna of electronic glasses is located at the end or middle of the temple, close to the user's ear or temple. The human body generates an inductance of approximately 500 to 750 nH, which attenuates electromagnetic waves, reducing the strength of wireless signals sent or received by the antenna and increasing the bit error rate. Consequently, the wireless communication performance of head-mounted electronic devices is further degraded.

[0047] In order to solve the above technical problems, according to an embodiment of the present disclosure, a lens assembly for a wireless electronic device is provided. The lens assembly includes a first lens, which is configured to provide a field of view (FOV) of the real world to the user's eyes, and the first lens has a first surface and a second surface opposite to each other. The lens further includes a first film arranged on the first surface, the first film including a first antenna electrode, the first antenna electrode being at least partially located within the FOV and serving as at least a part of the first antenna of the wireless electronic device. The lens assembly also includes a frame, which is configured to support the first lens on the user's body. Because the first lens serves as a device for providing the real-world FOV, the first antenna electrode located on the surface of the first lens is hardly blocked by the frame of the lens assembly and the housing of the wireless device, which improves the quality of wireless communication. The effect is particularly significant when the frame and / or the housing are made of conductive materials.

[0048] Reference Figure 1 , Figure 1 Schematic diagram of the structure of the lens assembly according to an embodiment of the present disclosure. Figure 1 As shown, the lens assembly 10 includes a first lens 11 , a first film 12 and a frame 13 .

[0049] The first lens 11 is configured to provide a FOV of the real world to the user's eye 21, and has a first surface 111 and a second surface 112 opposite to each other. Here, the real world refers to reality, that is, the real world that exists around the user and generally includes real objects. In the art, "real world" can be used as a relative concept to "virtual world", which refers to a computer-simulated world provided by virtual reality (VR) technology (such as voxel rendering, point cloud codec and point cloud rendering), which is generally three-dimensional (3D) and includes virtual objects. Here, FOV refers to the range of the observable world seen by the user's eye 21 at any given moment. Providing the FOV of the real world means that the first lens 11 enables the user to observe the area of ​​the real world through the first lens 11, and the range of this area is FOV. Typically, the range of this area is limited or defined by the configuration of the first lens (such as the shape and focal length of the first lens 11). FOV can be a solid angle, such as Figure 1 As shown by the area between the two dashed lines in FIG, the user's eye 21 can recognize one or more objects in the real world through this solid angle. The content within the FOV can be changed based on the movement of the lens frame or the user's movement. In practice, the specific shape of the FOV can be determined by the optical instrument of the lens assembly 10 (such as the first lens 11).

[0050] The first lens 11 can be made of a variety of materials, such as glass, plastic, and polymer (also known as organic glass). Typically, the first lens 11 is transparent or substantially transparent, and may be tinted as needed (for example, to block specific wavelengths of visible light). For example, to create a blurred vision effect, the first lens 11 may be translucent. Furthermore, the first lens 11 may be rigid or elastic, depending on practical needs. The term "lens" herein may be interpreted as: i) an optical component having one or both of its opposing surfaces (for example, the first surface 111 and the second surface 112 of the first lens 11) having a convex or concave shape; ii) an optical component having a non-uniform refractive index, thereby exhibiting optical properties similar to those of a convex or concave surface; or iii) an optical component, for example, positioned in front of the user's eye as a shield and configured to protect the eye. Those skilled in the art will appreciate that the lens may be implemented in other feasible forms. Therefore, each of the first surface 111 and the second surface 112 of the first lens 11 can be configured as a convex surface, a concave surface, a flat surface, or a surface of other shapes according to the FOV or visual perception ability of the eye 21.

[0051] The first film 12 is provided on the first surface 111 of the first lens 11 and includes a first antenna electrode 121. The first antenna electrode 121 is at least partially located within the FOV and serves as at least a portion of the first antenna of the wireless electronic device 10 (other portions are not shown). Here, the first film 12 can be directly provided on the first surface 111, that is, directly attached to the first surface 111, such as Figure 1 Alternatively, the first film 12 may be attached to the first surface 111 via an intermediate layer such as an adhesive.

[0052] Although in Figure 1 In the illustrated view, the first film 12 covers the entire first surface 111, but it should be understood that the first film 12 may only cover a portion of the first surface 111. In some embodiments, the first film 12 covers the portion of the first surface 111 where the first antenna electrode 121 is located. In this case, the interference of the first film 12 with the user's vision can be reduced to a certain extent.

[0053] The first antenna electrode 121 may be completely located within the FOV, such as Figure 1 As shown. Alternatively, the first antenna electrode 121 may be only partially located within the FOV, which reduces the possible obstruction of the user's line of sight. In addition, the first antenna electrode 121 can be configured in various shapes, such as a ring, a strip, an "F" shape, an "L" shape, or a zigzag shape, which is not limited here. Typically, the shape of the first antenna electrode 121 depends on the type of the first antenna, and the first antenna may be a monopole antenna, a dipole antenna, a loop antenna, a slot antenna, etc. In some embodiments, the first antenna electrode 121 or the portion thereof located in the FOV adopts a shape consistent with the edge of the FOV. That is, the first antenna electrode 121 is set at the edge of the FOV to reduce obstruction of the user's line of sight.

[0054] In some embodiments, the first surface 111 is configured so that, when the first lens 11 provides a field of view (FOV), it is positioned farther from the eye than the second surface 112. That is, when a user uses a wireless electronic device including the lens assembly 10, the first surface 111, where the first film 12 resides, faces outward (i.e., toward the real world), while the second surface 112 faces inward (i.e., toward the user). Compared to a case where the first surface 111 faces inward, the outward-facing first surface 111 places the first antenna electrode 121 at a greater distance from the user, reducing human interference with wireless signals transmitted / received by the first antenna. Furthermore, this configuration reduces interference from the first lens 11 with wireless communications, thereby improving the quality of wireless communications. It should be understood that in other embodiments, the first surface 111 may alternatively face inward, particularly when attenuation of wireless signals due to the human body and / or the first lens 11 is acceptable given the environmental risk of damage to the first antenna electrode 121. For example, a wireless electronic device including the lens assembly 10 may be used in an environment with extreme temperature, pressure, or humidity, and it is desirable that the first antenna electrode 121 be hidden from the real world by the first lens 11. Figure 2 , Figure 2 : is a schematic structural diagram of a lens assembly according to another embodiment of the present disclosure. Figure 1 On the basis of the structure shown, the first lens 11 and the first film 12 are turned from inside to outside, that is, the first antenna electrode 121 is arranged between the first lens 11 and the eye 21.

[0055] In some embodiments, the first antenna electrode 121 is configured to be located at a portion of the first film 12 within the FOV away from the user's body when the first lens 11 provides a FOV. That is, when the user uses a wireless electronic device including the lens assembly 10, the first antenna electrode 121 is set to be away from the human body within the FOV to reduce the interference of the human body with the wireless signals sent and / or received by the first antenna. The specific position of this portion of the first film 12 depends on the relative position between the first film 12 and the human body during the use of the wireless electronic device. For example, the wireless electronic device is smart glasses, and the lens assembly 10 corresponds to the left lens of the glasses (i.e., the lens in front of the user's left eye). In this case, this portion of the first film 12 can be located at the left edge of the left lens (relative to the wearer) because the right edge is too close to the nose, the upper edge is too close to the eyebrow, and the bottom edge is too close to the face. Similarly, when the lens assembly corresponds to the right lens of the glasses, this portion can be the right edge of the right lens. Reference Figure 3 , Figure 3 : is a schematic structural diagram of a lens assembly according to another embodiment of the present disclosure. Figure 1Based on the illustrated structure, the first antenna electrode 121 is moved to the side of the first film 12 away from the body (represented by the skin of the wearer's body 22), while still being partially within the FOV. Consequently, the increased distance between the first antenna electrode 121 and the body reduces interference with the wireless signal from the body. Although the first antenna electrode 121 is shown as being located at the rightmost side of the first film 12, it should be understood that in some embodiments, there may be a distance between the first antenna electrode 121 and the edge of the first film 12, particularly when there is no frame at that edge. It should also be understood that, alternatively, the first antenna electrode 121, when moved to the edge, may be positioned completely within the FOV.

[0056] In some embodiments, the first film 12 includes a substrate 122 in addition to the first antenna electrode 121, and the first antenna electrode 121 is a conductive pattern embedded in the substrate 122 or provided on a surface of the substrate 122 facing the first lens 11. Figure 4a and Figure 4b , Figure 4a and Figure 4b 1 is a schematic structural diagram of the first film according to an embodiment of the present disclosure. Take the first film 12 directly attached to the first lens 11 as an example. Figure 4a In the embodiment, the first antenna electrode 121 is provided on the contact surface between the substrate 122 and the first lens 11. Such a configuration can be achieved by first bonding the conductive pattern (i.e., the first antenna electrode 121) to the substrate 122 or the first lens 11 and then bonding the substrate 122 to the first lens 11, or by sequentially forming the first antenna electrode 121 and the substrate 122 on the first surface 111, both of which are simple in terms of manufacturing. Figure 4b In the embodiment, the first antenna electrode 121 is wrapped by the substrate 122. This configuration reduces the possibility of separation or deformation between the first film 12 and the first lens 11, which improves the robustness of the lens assembly. The case where the first film 12 is indirectly attached to the first lens 11 can be achieved by Figure 4a and Figure 4b The examples shown are derived by analogy. Figure 4a and Figure 4b In addition to the structure shown, the conductive pattern may alternatively be provided on the surface of the substrate 122 away from the first lens 11 (not shown). In this case, another layer may be provided to cover the surface of the substrate 122 away from the first lens 11 to protect the first antenna electrode 121.

[0057] Here, substrate 122 can serve as a protective coating on first lens 11, protecting both first surface 111 and first antenna electrode 121. First antenna electrode 121 is made of a conductive material such as metal, while substrate 122 is made of a non-conductive material such as a polymer. Similar to first lens 11, first film 12 can be rigid or elastic. When first lens 11 is elastic, first film 12 is preferably elastic to facilitate deformation of the first lens.

[0058] The first antenna may be formed solely of the first antenna electrode, or may include another component such as an additional antenna electrode. In the latter case, the additional antenna electrode may or may not be part of the first film 12, and may or may not be part of the lens assembly 10. For example, the other component may be an external component, and the lens assembly 10 may provide an interface for connecting the external component to the first antenna electrode 121 when wireless communication is performed using the first antenna.

[0059] The frame 13 is configured to support the first lens 11 on the user's body 22. Here, the body 22 may include a body part that directly contacts the frame 13 or indirectly provides support for the frame 13, for example, via the housing of the wireless electronic device. For example, when the wireless electronic device is smart glasses or a smart monocle, the body part may be the nose or ear; when the wireless electronic device is smart binoculars or a smart monocular, the body part may be the hand; or when the wireless electronic device is a smart mask or a smart helmet, the body part may be the head. The frame 13 may be used as part of the housing or may be independent of the housing. In the latter case, the frame 13 may be mounted on or housed by the housing. The present disclosure is not limited to this. For example, a pair of smart glasses used as a wireless electronic device and having a right lens as a lens assembly may be used. In this case, the frame 13 may include a right lens frame surrounding the right lens, and the housing may include a left lens frame, nose pads, temple bars, and a nose bridge. Alternatively, the right lens frame may also be used as part of the housing.

[0060] Despite Figure 1 Frame 13 is shown only on the left side of first lens 11 and first film 12, but the present disclosure is not limited thereto. In practice, any portion of frame 13 may be in physical contact with first lens 11 and / or first film 12, as long as it does not significantly obstruct the user's field of view. For example, frame 13 may surround the entire edge of first lens 11, or it may be secured to lens 11 at only one location along the edge. It should be understood that frame 13, together with first lens 11, may contribute to defining the FOV area.

[0061] In some embodiments, the entire frame 13 is made of a conductive material. For example, the frame 13 is an all-metal frame. Because a conductive frame can provide electromagnetic shielding for wireless signals, placing the first antenna electrode 121 within the frame is disadvantageous. Typically, a "window" made of non-conductive material should be provided in the conductive frame as an inlet and / or outlet for wireless signals, or the antenna should be exposed within the conductive frame. The former requires splicing conductive and non-conductive materials within the frame 13, while the latter requires breaking and opening windows in the conductive material. Both of these methods complicate the manufacturing process and reduce the robustness of the frame 13. In contrast, placing the first antenna electrode 121 on the first lens 11 is more beneficial because the integrity of the conductive frame can be maintained. Furthermore, because the real-world FOV is obscured by the conductive frame, electromagnetic shielding will be minimal. This ensures both the robustness of the lens assembly and the quality of wireless communication.

[0062] The aforementioned advantages can be achieved in addition to the case of a fully conductive frame 13. In some embodiments, the frame 13 includes a first portion made of a conductive material and a second portion made of a non-conductive material, where the area of ​​the second portion is smaller than the area of ​​the first antenna electrode 121. In other words, it is impossible to dispose the first antenna electrode 121 in the frame 13 without destroying the integrity of the conductive portion and causing significant interference to the wireless signal. Therefore, disposing the first antenna electrode 121 on the first lens 11 is also much more beneficial than other solutions. In addition, these benefits also apply to other situations where it is not suitable for the first antenna electrode 121 to be disposed in the frame 13, for example, when the space within the non-conductive housing cannot accommodate the first antenna electrode 121.

[0063] In some embodiments, the lens assembly 10 may further include an RF circuit (not shown) electrically connected to the first antenna electrode 121. Typically, for example, the RF circuit is electrically connected to the feed point of the first antenna of the first antenna electrode. Here, the RF circuit may be coupled to or part of the processing circuit and configured to convert an oscillating current or voltage into a signal compatible with the processing capabilities of the processing circuit, or vice versa. Typically, this conversion is achieved through modulation or demodulation. Specifically, the RF circuit modulates the oscillating current or voltage based on a signal generated by the processing circuit, and the first antenna then converts the modulated oscillating current or voltage into a wireless signal. Similarly, the first antenna converts a received wireless signal into an oscillating current or voltage, and the RF circuit demodulates the oscillating current or voltage to obtain a signal for processing by the processing circuit. Processing by the processing circuit may include, but is not limited to, encoding or decoding of visual signals, acoustic signals, or control signals. In practice, the processing circuit may be implemented in various ways. For example, the processing circuit may be an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a dedicated chip, etc. As another example, the processing circuit is a separate chip mounted on a printed circuit board (PCB), or may be integrated into another chip having multiple functions. The present disclosure is not limited to the above examples, and any appropriate chip may be used as the processing circuit as long as it can process wireless signals.

[0064] The RF circuit can be directly coupled to the first antenna electrode 121. Alternatively, in some embodiments, the lens assembly 10 further includes one or both of a communication cable 14 and an impedance matcher 15. The communication cable 14 is electrically connected between the RF circuit and the first antenna electrode 121. In one embodiment, the communication cable 14 is electrically connected to the first antenna electrode 121 at the aforementioned feed point to provide power to the first antenna. The communication cable can be insulated by a non-conductive coating or a non-conductive cover layer. In one embodiment, the communication cable can be a coaxial cable. The impedance matcher 15 is electrically connected between the RF circuit and the first antenna electrode 121 and is configured to suppress impedance mismatches between the first antenna and the RF circuit. Typically, on a Smith diagram, the impedance matcher adjusts the antenna impedance to approximately 50 ohms. If the communication cable 14 is present, the impedance matcher 15 can be disposed between the communication cable 14 and the first antenna electrode 121. In one embodiment, the impedance matcher 15 is electrically connected to the first antenna electrode 121 at the aforementioned feed point to provide power to the first antenna. The impedance matcher 14 may be a matching circuit including one or more inductors and / or one or more capacitors. The matching circuit may be a flexible printed circuit (FPC) or may be formed by laser direct structuring (LDS).

[0065] Here, one or both of the communication cable 14 and the impedance matcher 15 may be covered by the frame 13. That is, the communication cable 14 and / or the impedance matcher 15 may be embedded in the frame 13 or accommodated by the frame 13, thereby being protected by the frame 13 and not introducing obstructions in the FOV. In practice, the communication cable 14 and / or the impedance matcher 15 may be provided at any position of the frame 13 as long as there is an electrical connection between the RF circuit and the first antenna electrode 121. In some embodiments, the communication cable 14 and / or the impedance matcher 15 are provided at the edge of the first lens. Figure 5a and Figure 5b , Figure 5a and Figure 5b Schematic diagram of the structure of the lens assembly according to other embodiments of the present disclosure. Figure 5a In the embodiment shown, the communication cable 14 and / or the impedance matcher 15 are at least partially located at the edge of the first surface 111 (or the second surface, not shown). Figure 5b In the embodiment shown, the communication cable 14 and / or the impedance matcher 15 are at least partially located at the edge surface connecting the first surface 111 and the second surface 112. Figure 5a and Figure 5b The configuration of the frame 13 shown is merely illustrative and the present disclosure is not limited thereto. For example, the cross-section of the frame may be L-shaped instead of C-shaped, or the communication cable 14 and / or the impedance matcher 15 may be embedded in the frame 13 instead of being located in the cavity defined by the frame 13, the first lens 11, and the first frame 12. Figure 5a and Figure 5b , the electrical connection between the first antenna electrode 121 and the communication cable 14 and / or the impedance matcher 15 is shown as a line, but the actual connection point may be located in the first film 12 (i.e., a portion of the communication cable 14 and / or the impedance matcher 15 extends into the first film 12), outside the first film 12 (i.e., a portion of the first antenna electrode 121 extends out of the first film 12), or simply at the edge of the first film 12. In some embodiments, the connection point may even be implemented in the first lens 11.

[0066] Because the first antenna electrode 121 is at least partially located within the FOV, it is desirable for the first antenna electrode 121 to introduce minimal obstruction to ensure a clear view for the user. In some embodiments, the first film 12 is transparent or substantially transparent to achieve this. In this context, transparent first film 12 means that both the first antenna electrode 121 and the substrate 122 are transparent. In practice, the first antenna electrode 121 can be made of a transparent alloy such as indium tin oxide (ITO) or a transparent metal film, while the substrate 122 can be a transparent polymer such as polyethylene terephthalate (PET) or a transparent inorganic layer such as silicon dioxide. In other embodiments, the first film 12 is translucent—that is, one or both of the first antenna electrode 121 and the substrate 122 are translucent. This may compromise visual quality somewhat, but it increases the potential material options for manufacturing the first film 12. Similar to the first lens 11, the first film 12 can be tinted as desired. Additionally or alternatively, in some embodiments, the frame 13 can be configured to maintain the first antenna electrode 121 within a range between the eye 21 and the near point of the eye 21. The near point refers to the point closest to the eye at which an object accurately focuses on the retina when fully contained. Typically, the eye 21 does not focus closer than the near point, making the first antenna electrode difficult to perceive. Therefore, even if the first film 12 is not transparent, it is imperceptible when the size is sufficiently small. The smaller the size, the greater the distance between the first antenna electrode 121 and the eye 21. Therefore, obstruction of the user's field of vision can also be reduced. In some embodiments, one of the transparency, the distance to the eye 21, and the size of the first antenna electrode 121 can be determined based on the other two, so that the first antenna electrode 121 is negligible to the user's vision.

[0067] In addition to the first antenna electrode 121, the lens assembly 10 may further include one or more other antenna electrodes. Figure 6 , Figure 6 1 is a schematic structural diagram of a lens assembly according to another embodiment of the present disclosure. In some embodiments, the lens assembly 10 further includes a second film 13 located on the second surface 112, the second film 13 including a second antenna electrode 131, and the second antenna electrode 131 is at least partially located within the FOV.

[0068] Similar to the first film 12, the second film 13 can be disposed directly on the second surface 112 or indirectly attached to the second surface 112 via an intermediate layer. The second film 13 can cover the entire second surface 112 or only a portion thereof. In addition to the second antenna electrode 131, the second film can also include a substrate. The second antenna electrode 131 is a conductive pattern embedded in the substrate, disposed on the surface of the substrate facing the first lens 11, or disposed on the surface of the substrate facing away from the first lens 11 (with or without a covering layer). For other details of the second film 13, refer to the details of the first film 12 described above and will not be repeated here. It should be understood that, depending on actual needs, the second film 13 can be the same or different in material and / or shape as the first film 12.

[0069] Similar to the first antenna electrode 121, the second antenna electrode 131 can be located entirely or partially within the FOV and can have a shape that aligns with the edge of the FOV. When the first lens 11 provides a FOV, the second antenna electrode 131 can be located on a portion of the second film 13 that is located within the FOV and away from the user's body. The specific location of this portion of the second film 13 depends on the relative position between the second film 13 and the human body during use of the wireless electronic device. For other details of the second antenna electrode 131, reference can be made to the details of the first antenna electrode 121 described above and will not be repeated here. It should be understood that, depending on actual needs, the second antenna electrode 131 can be the same or different in material and / or shape as the first antenna electrode 121.

[0070] In some embodiments, the second antenna electrode 131 serves as another part of the first antenna. That is, the first antenna electrode 121 and the second antenna electrode 131 can together form the first antenna and cooperate when transmitting or receiving wireless signals. The shape of the second antenna electrode 131 can also depend on the type of the first antenna. Here, the two antenna electrodes can be electrically connected at the edge of the first lens 11 (not shown) or via a through-hole or slit (not shown) extending through the first lens 11. In one embodiment, the feed point of the first antenna can be the connection point between the first antenna electrode 121 and the second antenna electrode 131. That is, if the lens assembly 10 includes the aforementioned RF circuit, the aforementioned communication cable 14, and / or the aforementioned impedance matcher 15, one of these components is electrically connected to the two antenna electrodes at a connection point, which can be covered by the frame 13. It should be understood that the first antenna can include other components in addition to the first and second antenna electrodes 121, 131.

[0071] In other embodiments, the second antenna electrode 131 serves as at least part of the second antenna. That is, the first antenna electrode 121 and the second antenna electrode 131 are different antennas. Similar to the first antenna, the second antenna can be of various types, and the shape of the second antenna electrode 131 can depend on the type of the second antenna. Here, the first and second antennas can be configured to transmit wireless signals in different frequency bands and / or different wireless communication protocols to expand the communication adaptability of the lens assembly 10. For example, the two antennas can each be configured for communication in any two protocols, including 2.4 GHz Wi-Fi, 5 GHz Wi-Fi, Bluetooth, Zigbee, various Third Generation Partnership Project (3GPP) protocols, and the like. Alternatively, the first and second antennas can be configured to transmit wireless signals in the same frequency band and / or with the same communication protocol. In this case, the first and second antenna electrodes 121, 131 can be aligned in different directions to expand the wireless coverage of the lens assembly 10. Additionally or alternatively, the second antenna can serve as a backup in the event of a failure of the first antenna. The two antennas may share the same RF circuit, and signals between the RF circuit and the two antennas may be routed via filtering circuits and switching circuits, which are not limited herein.

[0072] In some embodiments, the first antenna electrode 121 and the second antenna electrode 131 do not overlap in the direction of the FOV perceived by the eye 21. Figure 7a , Figure 7a : is a structural diagram showing the positional relationship between the antenna electrodes of the lens assembly according to an embodiment of the present disclosure. Figure 7a As shown, the direction of the FOV perceived by the eye 21 (i.e., the line of sight) is indicated by the upward-pointing dotted line, and the first antenna electrode 121 and the second antenna electrode 131 are respectively arranged on the right and left sides of the first lens along this direction. The non-overlapping arrangement of the two antenna electrodes reduces the obstruction of the user's line of sight, especially when the two antenna electrodes are not completely transparent. It should be noted that the two antenna electrodes that do not overlap in the direction of eye perception do not mean that they do not overlap along the thickness direction of the first lens 11. Figure 7b , Figure 7b FIG. 1 is a structural diagram showing the positional relationship between antenna electrodes of a lens assembly according to another embodiment of the present disclosure. Figure 7bAs shown, second antenna 131 is illustrated as two portions 131-1 and 131-2, which can represent two distinct portions of second antenna electrode 131 or the same portion (i.e., separated only in cross-section). Along the thickness of lens 11, first antenna electrode 121 is located between these two portions 131-1 and 131-2, overlapping each of them. When eye 21 perceives the FOV, neither portion 131-1 nor portion 131-2 overlaps with first antenna electrode 121, as indicated by the two dashed lines representing the eye's line of sight. Therefore, this arrangement can still be considered non-overlapping in terms of eye perception. It should be understood that this non-overlapping arrangement, in addition to mitigating occlusion in the FOV, can also reduce interference between first antenna electrode 121 and second antenna electrode 131, primarily due to their spatial separation.

[0073] It should also be understood that although Figure 6 、 Figure 7a and Figure 7b In the embodiment, second film 13 is shown as being positioned between first film 12 and eye 21, but this structure can be reversed to achieve a structure in which first film 12 is positioned between second film 13 and eye 21. That is, second film 13 can be positioned on second surface 112 when second surface 112 faces outward and first surface 111 faces inward. The details of such an embodiment can be referred to the previous embodiment by exchanging first film 12 and second film 13, and exchanging first antenna electrode 121 and second antenna electrode 131, and will not be repeated here.

[0074] The lens assembly 10 may also have a display function. That is, visual information is displayed in the FOV and overlaps with the real world perceived by the eye 21. Generally, this technology belongs to the technical field of augmented reality (AR) or mixed reality (MR). In AR, messages and prompts can be displayed on the lens assembly 10 at a portion of the FOV. In MR, virtual objects can be displayed on the lens assembly 10 within the FOV and introduce some interactive operations with real objects perceived in the FOV. In order to realize the display function, additional optical components can be introduced into the lens assembly. Figure 8 , Figure 8 : is a schematic structural diagram of a lens assembly according to another embodiment of the present disclosure. Figure 2 Based on the structure shown, Figure 8 The lens assembly 10 shown also includes a waveguide 16. The waveguide 16 is attached to the first lens 11 and is at least partially disposed within the FOV. The waveguide 16 is configured to receive a light signal projected onto a portion of the waveguide 16 to form an image perceptible to the user's eye 21.

[0075] Here, the waveguide 16 may be an optical layer or sheet on which one or more gratings are disposed. As an example, a first region of the waveguide 16 has a first grating configured to receive an optical signal, and a second region of the waveguide 16 has a second grating configured to output an image. For example, Figure 8 As shown, the image source 30 sends an optical signal (such as Figure 8 ), such as being modulated into one or more colored light beams containing image information. In this case, the optical signal is coupled into the waveguide 16 via a first grating and then totally reflected within the waveguide until it is output from the waveguide 16 via a second grating and is perceived as an image by the user's eye 21. The grating may be implemented as micro grooves or micro protrusions on the surface of the waveguide 16. In addition, the introduction and extraction of the optical signal may be achieved by optical devices other than gratings, such as reflective holographic optical devices or reflective films. In practice, the waveguide 16 may include multiple layers, each layer being configured to receive a corresponding colored light beam and output a colored image, and the final image is displayed by overlapping the colored images of the multiple layers. For example, there may be three layers, corresponding to a red light beam, a green light beam, and a blue light beam, respectively.

[0076] Here, the image source 30 may be a part of the lens assembly 10, or may be a component independent of the lens assembly. In the latter case, the image source 30 may be a part of a wireless electronic device including the lens assembly. The present disclosure is not limited thereto.

[0077] like Figure 8 As shown, in some embodiments, the first film 12 is located between the waveguide 16 and the first lens 11. In this case, the first film 12 can be used as a bonding layer between the first lens 11 and the waveguide 16, and / or can be used as a buffer layer between the first lens 11 and the waveguide 16, especially when the first lens and the waveguide 16 are both made of rigid materials. In addition, the first antenna electrode 121 sandwiched between the first lens 11 and the waveguide 16 is protected on both sides. Alternatively, in some embodiments, the first film 12 can be located on the side of the first lens 11 away from the waveguide 16. Figure 9 , Figure 9 1 is a schematic structural diagram of a lens assembly according to another embodiment of the present disclosure. In addition to the waveguide 16, Figure 9 The structure shown is Figure 1 The structure shown is similar to that shown in FIG. The waveguide 16 can be attached directly to the first lens 11 or via an intermediate layer (not shown) such as an adhesive or a buffer layer. In such a structure, the first antenna electrode 121 is closer to the ambient space in the real world and farther away from the body 22, thereby achieving better wireless signal quality due to less interference from the human body.

[0078] Although FIG. 7 and FIG. 8 are shown based on the order in which the waveguide 16 is located between the first lens 11 and the eye 21, FIG. Figure 8 However, in other embodiments, these structures can be reversed, that is, the waveguide 16 can be configured to be located on the side of the first lens 11 away from the eye 21 during use. The present disclosure is not limited to any particular order.

[0079] As described above, the waveguide 16 includes a delicate structure for inputting, transmitting, and outputting optical signals, so it may be desirable to provide some protection for the waveguide 16. In some embodiments, in addition to the first mirror 11, another mirror is provided on the other side of the waveguide 16. Figure 10 , Figure 10 is another schematic diagram of a lens assembly according to another embodiment of the present disclosure. Figure 8 Based on the structure shown, the lens assembly 10 may further include a second lens 17 attached to the waveguide 16 , the second lens 17 being at least partially located within the FOV, and the waveguide 16 being located between the first lens 11 and the second lens 17 .

[0080] Similar to the first lens 11, the second lens 17 can be made of various materials, such as glass, plastic, or polymer. The second lens 17 can be transparent, substantially transparent, or translucent, and can be colored as desired. The second lens 11 can be rigid or elastic. For other details of the second lens 17, reference can be made to the details of the first lens 11 described above and will not be repeated here. It should be understood that, depending on actual needs, the second lens 17 can be the same as or different from the first lens 11 in terms of material and / or shape.

[0081] In some embodiments, when the first lens 11 provides FOV, the first lens 11 is located farther away from the eye 21 than the second lens 17, such as Figure 10As shown. That is, when a user uses a wireless electronic device including lens assembly 10, first lens 11, where first film 12 resides, is positioned outside waveguide 16 (i.e., closer to the real world), while second surface 112 is positioned inside waveguide 16 (i.e., closer to the user). The distance between first antenna electrode 121 and the user is greater than when the first lens is positioned inside and second lens 17 is positioned outside, reducing human interference with wireless signals transmitted / received by the first antenna. Furthermore, this configuration reduces interference from waveguide 16 with wireless communications, thereby improving the quality of wireless communications. It should be understood that in some embodiments, first lens 111 may alternatively be positioned inside, particularly when attenuation of wireless signals due to human contact and / or waveguide 16 is acceptable given the environmental risk of damage to first antenna electrode 121. For example, a wireless electronic device including lens assembly 10 may be used in environments with extreme temperature, pressure, or humidity, and it may be desirable for first antenna electrode 121 to be concealed from the real world by first lens 11. That is to say, the specific order between the first lens 11 and the second lens 17 is not limited here and can be determined according to actual needs.

[0082] Similar to the first lens 11, the second lens 17 may be provided with another antenna electrode. Figure 11 , Figure 11 FIG2 is a schematic diagram of a lens assembly according to another embodiment of the present disclosure. In some embodiments, the second lens has a third surface 173 and a fourth surface 174. The lens assembly 10 further includes a third film 18 located on the third surface 173. The third film 18 includes a third antenna electrode 181, and the third antenna electrode is at least partially located within the FOV.

[0083] Similar to the first film 12, the third film 18 can be disposed directly on the third surface 173 or indirectly attached to the third surface 174 via an intermediate layer. The third film 18 can cover the entire third surface 174 or only a portion thereof. In addition to the third antenna electrode 181, the third film 18 can also include a substrate. The third antenna electrode 181 is a conductive pattern embedded in the substrate, disposed on the surface of the substrate facing the second lens 17, or disposed on the surface of the substrate facing away from the second lens 17 (with or without a covering layer). For other details of the third film 18, refer to the details of the first film 12 described above and will not be repeated here. It should be understood that, depending on actual needs, the third film 18 can be made of the same material and / or shape as the first film 12, or different materials.

[0084] Similar to the first antenna electrode 121, the third antenna electrode 181 can be located entirely or partially within the FOV and can have a shape that aligns with the edge of the FOV. When the first lens 11 provides a FOV, the third antenna electrode 181 can be located in a portion of the third film 18 within the FOV that is away from the user's body. The specific location of this portion of the third film 18 depends on the relative position between the third film 18 and the human body during use of the wireless electronic device. For other details of the third antenna electrode 181, refer to the details of the first antenna electrode 121 described above and will not be repeated here. It should be understood that, depending on actual needs, the third antenna electrode 181 can be the same or different in material and / or shape as the first antenna electrode 121.

[0085] It should be understood that the third antenna electrode 181 can achieve technical advantages similar to those achieved by the first antenna electrode 121. Although the third surface 173 of the second mirror 17 is shown as a surface facing the waveguide 16, it should be understood that it can alternatively be a surface away from the waveguide 16. Details of this configuration can be referred to in relation to Figure 9 The above description will not be repeated here.

[0086] In some embodiments, the first antenna electrode 121 and the third antenna electrode 181 do not overlap in the direction of the FOV perceived by the eye 21. Figure 12 , Figure 12 FIG. 1 is a structural diagram showing the positional relationship between antenna electrodes of a lens assembly according to another embodiment of the present disclosure. Figure 12 As shown, the direction of the FOV perceived by the eye 21 (i.e., line of sight) is indicated by the upward-pointing dashed line, and the first antenna electrode 121 and the second antenna electrode 131 are respectively arranged along this direction on the right and left sides of the first lens. The non-overlapping arrangement of the two antenna electrodes reduces obstruction of the user's line of sight, especially when the two antenna electrodes are not completely transparent. For further details of this configuration, please refer to the Figure 7a and Figure 7b The above description will not be repeated here.

[0087] In some embodiments, the third antenna electrode 181 serves as another portion of the first antenna. That is, the first antenna electrode 121 and the third antenna electrode 181 can together form the first antenna and cooperate when transmitting or receiving wireless signals. The shape of the third antenna electrode 181 can also depend on the type of the first antenna. Here, the two antenna electrodes can be electrically connected at the edges (not shown) of the first and second lenses 11, 17, or via a through-hole or slit (not shown) extending through the first lens 11, waveguide 16, and / or second lens 17. In one embodiment, the feed point of the first antenna can be the connection point between the first antenna electrode 121 and the third antenna electrode 181. Details of this configuration can be referenced to the previously described configuration in which the first and second antenna electrodes 121, 131 can together form the first antenna and will not be repeated here.

[0088] In an alternative embodiment, third antenna electrode 181 functions as at least a portion of a third antenna. That is, first antenna electrode 121 and third antenna electrode 181 are different antennas. Similar to the first antenna, the third antenna can be of various types, and the shape of third antenna electrode 181 can depend on the type of the third antenna. The first and second antennas can be configured to transmit wireless signals in different frequency bands and / or different wireless communication protocols, or in the same frequency band and / or the same communication protocol. Details of this configuration can be referenced with the previously described details of the configuration in which first antenna electrode 121 and second antenna electrode 131 are different antennas and will not be repeated here.

[0089] In other embodiments, the lens assembly 10 includes all of the above-mentioned antenna electrodes, namely the first antenna electrode 121, the second antenna electrode 131, and the third antenna electrode 181. In this case, the third antenna electrode 181 can be used as another part of the second antenna. That is, the second antenna electrode 131 and the third antenna electrode 181 can together form a second antenna and cooperate when sending or receiving wireless signals. In addition, the first antenna and the second antenna can be configured to transmit wireless signals in different frequency bands and / or different wireless communication protocols, or to transmit wireless signals in the same frequency band and / or the same communication protocol. Alternatively, the three antenna electrodes can be electrically connected and form at least a part of the first antenna. The details of these configurations can be referred to the details of the aforementioned configurations and will not be repeated here.

[0090] In addition, similar to the first lens 11 having the first film 12 and the second film 13, a fourth film can also be provided on the fourth surface 114 of the second lens 17, and the fourth film includes a fourth antenna electrode that is at least partially located in the FOV. The details of the fourth film and the fourth antenna electrode can refer to the details of the second film 13 and the second antenna electrode 131, and are not repeated here. The fourth antenna electrode can be used as part of a fourth antenna, or can be electrically connected to another antenna electrode and used as part of a corresponding antenna. The details of the above configuration can refer to the previous description of the other antenna electrodes, and are not repeated here. Distributing an antenna between different films will reduce the size of the antenna electrode in each layer, thereby reducing the potential obstruction of the FOV by the antenna. In addition, in the case where the lens assembly has multiple of the aforementioned films having antenna electrodes, the antenna electrodes can overlap with each other in the direction in which the eye 21 perceives the FOV.

[0091] In the above, lens assemblies are shown according to embodiments of the present disclosure. In another aspect, according to embodiments of the present disclosure, a wireless electronic device is provided. The wireless electronic device includes at least one lens assembly, each of which is the aforementioned lens assembly.

[0092] Here, the wireless electronic device can take various forms. As an example, the wireless electronic device is smart glasses and includes two lens assemblies corresponding to the left and right lenses of the smart glasses. As another example, the wireless electronic device is a smart monocle and includes a single lens assembly. As another example, the wireless electronic device is a monocular, binocular, or microscope, and the objective lens and / or eyepiece are the lens assemblies. Furthermore, the wireless electronic device can be a smart helmet, and the visor of the smart helmet is the lens assembly.

[0093] In some embodiments, the wireless electronic device further comprises a conductive housing configured to fix or accommodate at least one lens assembly. The entire housing may be made of a conductive material.

[0094] In some embodiments, the two lens assemblies share the RF circuit, and the RF circuit is located between the two lens assemblies. For example, the two lens assemblies correspond to the left lens and the right lens of the smart glasses, and the RF circuit is located at the bridge of the smart glasses.

[0095] In some embodiments, the first antenna of one lens assembly in at least one lens assembly and the first antenna of another lens assembly in at least one lens assembly are configured to send or receive wireless signals in different frequency bands. For example, the first antenna of the left lens of the smart glasses is configured for wireless communication under 2.4 GHz Wi-Fi or Bluetooth, while the first antenna of the right lens of the smart glasses is configured for communication under 5 GHz Wi-Fi. Alternatively, the first antennas of different lens assemblies can be configured to send or receive wireless signals in the same frequency band. In this case, wireless communication can have better coverage, and / or one lens assembly can be used as a backup for the other lens assembly in wireless communication.

[0096] In the following, smart glasses are used as an example of wireless electronic devices for explanation. Figure 13 , Figure 13 FIG is a schematic diagram of a portion of a lens assembly in smart glasses according to another embodiment of the present disclosure. Figure 13 As shown, the right lens of the smart glasses is the aforementioned lens assembly, with a first film 12 including a first antenna electrode (not shown) attached to the first surface of the first lens 11. An impedance matcher 15 electrically connected to the first antenna electrode and a communication cable 14 electrically connected to the impedance matcher 15 are provided on the edge surface of the first lens 11. The communication cable 14 and impedance matcher 15 are covered by the right edge of the right lens frame in the lens assembly and are connected to the RF circuitry (not shown) located in the right temple stem (not shown) of the smart glasses. The right temple stem and right lens frame can be two parts of the frame 13. Alternatively, the right temple stem can be separate from the frame 13 and serve as part of the housing of the smart glasses. The frame 13 and / or the housing can be made of metal. Furthermore, the left lens of the smart glasses can be another lens assembly and can have the same (symmetrical) structure as the right lens.

Therefore, one embodiment may refer to other embodiments for the same or similar components. Since the wireless electronic device disclosed in this embodiment corresponds to the lens disclosed in this embodiment, the description of the device embodiment is simplified, and reference may be made to the relevant portions of the lens assembly embodiment.
