Description

Technical Field

[0001] This application belongs to the field of smart terminal technology, specifically relating to a lens and smart glasses. Background Technology

[0002] With the advancement of mobile communication systems, smart glasses are becoming increasingly diverse in style. Smart glasses can serve as a medium for users to interact with the real or virtual world, including Augmented Reality (AR) and Virtual Reality (VR). However, if users want to experience immersive technologies like AR and VR, they need to use different devices, requiring switching between them, which is costly and inconvenient. Summary of the Invention

[0003] This application provides a lens and smart glasses that can solve the problem that users who want to experience immersive technologies such as AR and VR need to use different devices and switch between different devices to experience different technologies, which is quite troublesome.

[0004] In a first aspect, embodiments of this application provide a lens, the lens comprising a first lens layer, a first transparent electrode layer, an electrochromic layer, a second transparent electrode layer, and a second lens layer stacked sequentially;

[0005] In the first mode, the light transmittance of the electrochromic layer is controlled by the first transparent electrode layer and the second transparent electrode layer to be a first light transmittance; in the second mode, the light transmittance of the electrochromic layer is controlled by the first transparent electrode layer and the second transparent electrode layer to be a second light transmittance, wherein the first light transmittance is less than the second light transmittance.

[0006] In a second aspect, embodiments of this application provide a smart glasses, including: a lens, a frame, temples, and a control chip disposed on the frame or temples as described in the first aspect, wherein the lens is disposed on the frame, the frame is connected to the temples, and the lens is electrically connected to the control chip;

[0007] In the first mode, the control chip controls the light transmittance of the lens to a first light transmittance; in the second mode, the control chip controls the light transmittance of the lens to a second light transmittance; the first light transmittance is less than the second light transmittance.

[0008] In this embodiment, the lens includes a first lens layer, a first transparent electrode layer, an electrochromic layer, a second transparent electrode layer, and a second lens layer stacked sequentially. When the lens is in a first mode, the first and second transparent electrode layers control the light transmittance of the electrochromic layer to a first light transmittance. When the lens is in a second mode, the first and second transparent electrode layers control the light transmittance of the electrochromic layer to a second light transmittance, where the first light transmittance is less than the second light transmittance. This embodiment, by incorporating an electrochromic layer in the lens and controlling its light transmittance through the first and second transparent electrode layers, allows the lens to be in a low light transmittance state when the lens needs to be in a first light transmittance state to reduce external light passing through. Conversely, when the lens needs to be in a high light transmittance state, the electrochromic layer is controlled to be in a second light transmittance state to allow external light to pass through. By setting the electrochromic layer, the amount of light passing through the lens can be altered, enabling smart glasses using this lens to freely switch between virtual reality and augmented reality modes without needing to change the smart glasses, making operation simple and convenient.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The following is in conjunction with the appendix Figures 1 to 11 The present application provides a detailed description of a lens 120 and smart glasses 10 through specific embodiments and application scenarios.

[0034] like Figure 1-7 The figure shows a schematic diagram of a lens 120 provided in an embodiment of this application. As shown, the lens 120 includes a first lens layer 121, a first transparent electrode layer 122, an electrochromic layer 1231, a second transparent electrode layer 124, and a second lens layer 125, which are stacked sequentially.

[0035] In the first mode, the light transmittance of the electrochromic layer 1231 is controlled by the first transparent electrode layer 122 and the second transparent electrode layer 124 to be a first light transmittance; in the second mode, the light transmittance of the electrochromic layer 1231 is controlled by the first transparent electrode layer 122 and the second transparent electrode layer 124 to be a second light transmittance, wherein the first light transmittance is less than the second light transmittance.

[0036] Among them, the electrochromic layer 1231 is used for color change.

[0037] It is worth noting that the material of the electrochromic layer 1231 can be the inorganic electrochromic material tungsten trioxide (WO3), or it can be indium tin oxide (ITO), lithium niobate (LiNbO3), etc.

[0038] The first mode can be a low transmittance mode. For example, when lens 120 is applied to smart glasses 10 and the smart glasses are in virtual reality (VR) mode, it is necessary to reduce the amount of external light passing through lens 120. This can be achieved by controlling the transmittance of the electrochromic layer 1231 to a first transmittance mode, thereby blocking at least part of the external light. The second mode can be a high transmittance mode. For example, when lens 120 is applied to smart glasses 10 and the smart glasses are in augmented reality (AR) mode, external light is required. This can be achieved by controlling the transmittance of the electrochromic layer 1231 to a second transmittance mode, allowing external light to pass through.

[0039] It is worth noting that the light transmittance of the lens 120 is controlled by controlling the voltage between the first transparent electrode layer 122 and the second transparent electrode layer 124, thereby controlling the light transmittance of the electrochromic layer 1231. For example, when the light transmittance is zero, the lens 120 becomes black, and when the light transmittance is 100%, the lens 120 becomes transparent. Specifically, a voltage is applied between the first transparent electrode layer 122 and the second transparent electrode layer 124. If there is a positive voltage difference between the first transparent electrode layer 122 and the second transparent electrode layer 124, the light transmittance of the electrochromic layer 1231 is the second light transmittance; if there is a negative voltage difference between the first transparent electrode layer 122 and the second transparent electrode layer 124, the light transmittance of the electrochromic layer 1231 is the first light transmittance.

[0040] The first lens layer 121 and the second lens layer 125 can be used to protect the first transparent electrode layer 122, the electrochromic layer 1231 and the second transparent electrode layer 124.

[0041] In this embodiment, the lens 120 includes a first lens layer 121, a first transparent electrode layer 122, an electrochromic layer 1231, a second transparent electrode layer 124, and a second lens layer 125, which are stacked sequentially. When the lens 120 is in a first mode, the light transmittance of the electrochromic layer 1231 is controlled by the first transparent electrode layer 122 and the second transparent electrode layer 124 to be a first light transmittance. When the lens 120 is in a second mode, the light transmittance of the electrochromic layer 1231 is controlled by the first transparent electrode layer 122 and the second transparent electrode layer 124 to be a second light transmittance, wherein the first light transmittance is less than the second light transmittance. This embodiment of the application provides an electrochromic layer 1231 in the lens 120. The transmittance of the electrochromic layer 1231 is controlled by a first transparent electrode layer 122 and a second transparent electrode layer 124. When the lens 120 needs to be at a low transmittance, the transmittance of the electrochromic layer 1231 is controlled to a first transmittance to reduce external light passing through the lens 120. When the lens 120 needs to be at a high transmittance, the transmittance of the electrochromic layer 1231 is controlled to a second transmittance to allow external light to pass through the lens 120. By providing the electrochromic layer 1231, the amount of light passing through the lens 120 can be changed, allowing the smart glasses 10 using the lens to freely switch between virtual reality mode and augmented reality mode. Both modes can be achieved without replacing the smart glasses 10, making operation simple and convenient.

[0042] In one possible embodiment of this application, the lens 120 may further include an electrolyte layer 1232, which is disposed on the side of the electrochromic layer 1231 opposite to the first transparent electrode layer 122.

[0043] The electrolyte layer 1232 is used to conduct electrons or ions so that the voltage in the transparent electrode layer is transmitted to the electrochromic layer 1231, causing the electrochromic layer 1231 to change color.

[0044] In one specific embodiment of this application, the first light transmittance is zero, and the electrochromic layer 1231 turns black.

[0045] In other words, when the lens 120 needs to be completely opaque, the first transmittance can be set to zero so that the electrochromic layer 1231 turns black, so that external light cannot pass through the lens 120.

[0046] In one possible embodiment of this application, the lens 120 has a dimming area 126 and a wiring area 127. An electrochromic layer 1231 is disposed in the dimming area 126. A first transparent electrode layer 122 is disposed between the first lens layer 121 and the electrochromic layer 1231. A second transparent electrode layer 124 is disposed between the electrochromic layer 1231 and the second lens layer 125. The first transparent electrode layer 122 and the second transparent electrode layer 124 cover the dimming area 126 and extend into the wiring area 127.

[0047] Since the transmittance of the electrochromic layer 1231 needs to be controlled through the first transparent electrode layer 122 and the second transparent electrode layer 124, the lens 120 is divided into two parts: a dimming area 126 and a wiring area 127. The transmittance of the lens 120 is changed in the dimming area 126, and wiring is done in the wiring area 127 to control the transmittance of the electrochromic layer 1231.

[0048] In other words, the control chip that controls the light transmittance of the electrochromic layer 1231 can be connected to the first transparent electrode layer 122 and the second transparent electrode layer 124 through the wiring area 127 so as not to affect the overall light transmittance and aesthetics of the lens 120.

[0049] The dimming area 126 can be located in the middle part of the lens 120, and the wiring area 127 can be located at the edge of the 120, so that the wiring does not affect the light passing through the dimming area 126.

[0050] In this embodiment, the electrochromic layer 1231 is only disposed in the dimming area 126, while the first transparent electrode layer 122 and the second transparent electrode layer 124 are disposed in both the dimming area 126 and the wiring area 127, and are connected to the control chip in the wiring area 127. Through this connection method, the connecting components, such as wires or flexible printed circuit boards (FPCs), can be hidden in the wiring area 127 of the lens 120, making the lens 120 look cleaner and more aesthetically pleasing.

[0051] In one possible embodiment of this application, the wiring area 127 includes a first terminal and a second terminal, the first terminal being electrically connected to a first transparent electrode layer 122, and the second terminal being electrically connected to a second transparent electrode layer 124.

[0052] In other words, the portions of the first transparent electrode layer 122 and the second transparent electrode layer 124 that extend to the wiring area 127 can be electrically connected to the terminals for connection to an external control chip, which controls the transparency of the electrochromic layer 1231.

[0053] By setting the first terminal and the second terminal in the wiring area 127, the first terminal, the second terminal, and related wires or flexible circuit boards can be hidden in the wiring area 127 without affecting the dimming area 126, making the lens 120 look cleaner and more aesthetically pleasing overall.

[0054] The first terminal is disposed on the side of the first transparent electrode layer 122 facing the second transparent electrode layer 124, and the second terminal is disposed on the side of the second transparent electrode layer 124 facing the first transparent electrode layer 122.

[0055] In other words, the first terminal and the second terminal can be located in the area opposite to the first transparent electrode layer 122 and the second transparent electrode layer 124. This arrangement allows the first terminal and the second terminal to be hidden between the first transparent electrode layer 122 and the second transparent electrode layer 124, which does not affect the transparency of the electrochromic layer 1231 or the overall aesthetics of the lens 120.

[0056] like Figure 6-11 The figure shows a schematic diagram of the structure of a smart glasses 10 provided in an embodiment of this application. As shown, the smart glasses 10 includes: a lens 120, a frame 110, temples 200 as provided in any of the above embodiments, and a control chip 900 disposed on the frame 110 or the temples 200. The lens 120 is disposed on the frame 110, the frame 110 is connected to the temples 200, and the lens 120 is electrically connected to the control chip 900.

[0057] In the first mode, the control chip 900 controls the light transmittance of the lens 120 to be a first light transmittance; in the second mode, the control chip 900 controls the light transmittance of the lens 120 to be a second light transmittance; the first light transmittance is less than the second light transmittance.

[0058] In other words, the lens 120 provided in the above embodiments can be applied to the smart glasses 10 so that the smart glasses 10 can change the light transmittance to adapt to different scene requirements.

[0059] The first mode can be Virtual Reality (VR) mode, where the smart glasses 10 is in VR mode. In this mode, it is necessary to isolate external light and reduce the amount of external light passing through the smart glasses 10. The control chip 900 can control the light transmittance of the electrochromic layer 1231 to a first light transmittance to block at least part of the external light. The second mode can be Augmented Reality (AR) mode, where the smart glasses 10 is in AR mode. In this mode, external light is required, and it is necessary to allow external light to pass through the smart glasses 10. The control chip 900 can control the light transmittance of the electrochromic layer 1231 to a second light transmittance to allow external light to pass through.

[0060] It is worth noting that the control chip 900 controls the light transmittance of the electrochromic layer 1231 by controlling the voltage between the first transparent electrode layer 122 and the second transparent electrode layer 124. For example, when the light transmittance is zero, the lens 120 becomes black, and when the light transmittance is 100%, the lens 120 becomes transparent. Specifically, when a voltage is applied between the first transparent electrode layer 122 and the second transparent electrode layer 124, if there is a positive voltage difference between the two layers, the light transmittance of the electrochromic layer 1231 is the second light transmittance; if there is a negative voltage difference, the light transmittance of the electrochromic layer 1231 is the first light transmittance.

[0061] The first lens layer 121 and the second lens layer 125 can be used to protect the first transparent electrode layer 122, the electrochromic layer 1231 and the second transparent electrode layer 124, and can also be used for display when the smart glasses 10 is in augmented reality mode. The first lens layer 121 can be set on the side facing the user when the user wears it, and the second lens can be set on the side of the first lens layer 121 away from the user. In this setting, the first lens layer 121 can also be used for display when the smart glasses 10 is in virtual reality mode.

[0062] The first transparent electrode layer 122 and the second transparent electrode layer 124 are used to connect to the control chip and receive voltage from the control chip 900, which is then conducted to the electrochromic layer 1231 to control the light transmittance of the electrochromic layer 1231.

[0063] In this embodiment, the smart glasses 10 includes a lens 120, a frame 110, temples 200, and a control chip 900 disposed on the frame 110 or temples 200. The lens 120 is disposed on the frame 110, the frame 110 is connected to the temples 200, and the lens 120 is electrically connected to the control chip 900. In the first mode, the control chip 900 controls the light transmittance of the lens 120 to a first light transmittance. In the second mode, the control chip 900 controls the light transmittance of the lens 120 to a second light transmittance. This embodiment of the application sets up a lens 120 with an electrochromic layer 1231 and a control chip 900 in the smart glasses 10. When the smart glasses 10 needs to be in virtual reality mode, the light transmittance of the lens 120 is controlled to a first light transmittance to reduce the amount of external light passing through the smart glasses 10. When the smart glasses 10 needs to be in augmented reality mode, the light transmittance of the lens 120 is controlled to a second light transmittance to allow external light to pass through the smart glasses 10. By setting up the lens 120 with the electrochromic layer 1231, the smart glasses 10 can freely switch between virtual reality mode and augmented reality mode without replacing the smart glasses 10, which is simple and convenient to operate.

[0064] In one possible implementation of this application, when the smart glasses 10 is in a first mode, the control chip 900 applies a negative voltage difference between the first transparent electrode layer 122 and the second transparent electrode layer 124 of the lens 120 to control the light transmittance of the electrochromic layer 1231 of the lens to a first light transmittance; when the smart glasses 10 is in a second mode, the control chip 900 applies a positive voltage difference between the first transparent electrode layer and the second transparent electrode layer 124 to control the light transmittance of the electrochromic layer 1231 to a second light transmittance.

[0065] In other words, the control chip 900 controls the light transmittance of the lens 120 by controlling the voltage between the first transparent electrode layer 122 and the second transparent electrode layer 124, thereby controlling the light transmittance of the electrochromic layer 1231. For example, when the light transmittance is zero, the lens 120 becomes black, and when the light transmittance is 100%, the lens 120 becomes transparent. Specifically, a voltage is applied between the first transparent electrode layer 122 and the second transparent electrode layer 124. If there is a positive voltage difference between the first transparent electrode layer 122 and the second transparent electrode layer 124, the light transmittance of the electrochromic layer 1231 is the second light transmittance; if there is a negative voltage difference between the first transparent electrode layer 122 and the second transparent electrode layer 124, the light transmittance of the electrochromic layer 1231 is the first light transmittance.

[0066] Specifically, the first transparent electrode layer 122 and the second transparent electrode layer 124 are used to connect to the control chip and receive voltage from the control chip 900, which is then conducted to the electrochromic layer 1231 to control the light transmittance of the electrochromic layer 1231.

[0067] As described above, both the first transparent electrode layer 122 and the second transparent electrode layer 124 are connected to the control chip 900. They can be connected to the control chip through the side of the first transparent electrode layer 122 and the side of the second transparent electrode layer 124, or they can be connected to the control chip through other locations.

[0068] In one possible embodiment of this application, the smart glasses 10 may further include a flexible circuit board 710, and the lens 120 includes a first terminal and a second terminal. The first terminal is electrically connected to a first transparent electrode layer 122, and the second terminal is electrically connected to a second transparent electrode layer 124. The flexible circuit board 710 is connected to the first terminal and the second terminal. The lens 120 is electrically connected to the control chip 900 through the flexible circuit board 710.

[0069] In other words, the first transparent electrode layer 122 and the second transparent electrode layer 124 can be connected to the control chip 900 through the first terminal, the second terminal and the flexible circuit board 710, respectively.

[0070] Since the lens 120 of the smart glasses 10 may be irregular in shape, using a flexible circuit board to connect the first transparent electrode layer 122 and the second transparent electrode layer 124 to the control chip 900 can make the connection smoother and easier to hide in the lens 120.

[0071] The first terminal and the second terminal can be contact surfaces 600 (PAD) respectively disposed on two opposite surfaces of the first transparent electrode layer 122 and the second transparent electrode layer 124. A gold surface, i.e., contact surface 600, is also disposed at a preset position on the flexible circuit board 710. The first transparent electrode layer 122 and the second transparent electrode layer 124 are both connected to the contact surface 600 on the flexible circuit board 710 through the contact surface 600.

[0072] In other words, the first transparent electrode layer 122 and the second transparent electrode layer 124 are in contact with the contact surface 600 on the flexible circuit board 710 through the contact surface 600, so as to achieve mutual connection.

[0073] Specifically, they can be connected by welding or by using conductive materials.

[0074] In one example, the contact surface 600 of the first transparent electrode layer 122 and the second transparent electrode layer 124 is connected to the contact surface 600 of the flexible circuit board 710 through an anisotropic conductive adhesive film 800.

[0075] Since the lenses 120 of the smart glasses 10 are generally small in size and thin, welding may not provide a strong bond, affecting usability. Therefore, in this embodiment, an anisotropic conductive film (ACF) is used to connect the contact surfaces 600 of the first transparent electrode layer 122 and the second transparent electrode layer 124 to the contact surface 600 of the flexible circuit board 710. The anisotropic conductive film 800 can solve the problem of connecting fine wires that some connectors cannot handle. Therefore, using anisotropic conductive film 800 for connection makes the connection more secure.

[0076] In one example, the flexible circuit board 710 can be connected to the control chip 900 via the first connector 730, or via other means such as soldering.

[0077] To facilitate assembly, the embodiments of this application use a first connector 730 to connect the flexible circuit board 710 to the control chip 900. Compared with direct soldering or bonding, using a connector makes assembly more convenient.

[0078] The first connector 730 includes a male end and a female end, which are respectively disposed on the flexible circuit board 710 and the control chip 900. After the male end and the female end make contact, the flexible circuit board 710 and the control chip 900 are electrically connected.

[0079] In one possible embodiment of this application, the smart glasses 10 further includes a switch 400 disposed on the temple 200. The switch 400 is connected to the control chip 900, and the control chip 900 controls the light transmittance of the lens 120 according to the switching of the switch 400.

[0080] In this embodiment, a switch 400 is used to control the light transmittance of the lens 120, making control more convenient. When the user needs the smart glasses 10 to be in virtual reality mode, the switch 400 can be operated to set the light transmittance of the lens 120 to the first light transmittance to reduce the amount of external light passing through the smart glasses 10. When the user needs the smart glasses 10 to be in augmented reality mode, the switch 400 can be operated to set the light transmittance of the lens 120 to the second light transmittance to allow external light to pass through the smart glasses 10. The smart glasses 10 can be switched between virtual reality mode and augmented reality mode at will by operating the switch 400, making operation more convenient.

[0081] Optionally, the smart glasses 10 may also include a power switch 500, which is connected to a toggle switch 400. The toggle switch 400 can only be operated after the power switch 500 is turned on. By setting the power switch 500, accidental operation by the user can be avoided.

[0082] In one example, the toggle switch 400 is connected to the control chip 900 via a second flexible circuit board 720.

[0083] Since the temple 200 is thin, it may also be irregular in shape, such as curved or zigzag structure. Using a second flexible circuit board 720 can make the connection smoother, the connection more secure, and easier to hide in the temple 200.

[0084] The second flexible circuit board 720 can be connected to the control chip via the second connector 740.

[0085] In this embodiment, a second connector 740 is used to connect the second flexible circuit board to the control chip. Compared with direct soldering or bonding, using a connector makes assembly more convenient.

[0086] The second connector 740 includes a male end and a female end, which are respectively disposed on the second flexible circuit board 720 and the control chip 900. After the male end and the female end make contact, the second flexible circuit board 720 and the control chip 900 are electrically connected.

[0087] The connector described in the above embodiments may be one part, for example, the male end is soldered to the circuit board 1000 (Printed Circuit Board, PCB) where the control chip 900 is located, and the other part, such as the female end, is soldered to the flexible circuit board 710 or the second flexible circuit board 720. During assembly, the two parts are plugged together to achieve mutual connection, so that the flexible circuit board 710 and the control chip 900 are electrically connected, and the second flexible circuit board 720 and the control chip 900 are electrically connected.

[0088] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
