Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to providing an lead electrode, an electrochromic component, and a color-changing device. Background Technology

[0002] Lead-out electrodes are conductive elements used in electronic devices to connect internal circuits or electronic modules to external circuits.

[0003] In traditional electronic device connection structures, each electronic module is typically electrically connected to external circuits via an independent lead-out electrode. However, with the increase in the functionality and integration of electronic devices, the number of independent lead-out electrodes required also increases, leading to complex circuit layouts, difficult wiring, and multiple independent lead-out electrodes occupying a large amount of wiring space, which is not conducive to the miniaturization of electronic devices. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0049] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0050] In some embodiments, refer to Figure 1 As shown, this application provides a lead electrode 1, including: a first end 101 and a second end 102. The first end 101 is provided with a plurality of first electrical connection points 103, each first electrical connection point 103 being connected to a different power supply terminal; the second end 102 is provided with a plurality of second electrical connection points 104, each second electrical connection point 104 being connected to an external circuit; the first electrical connection points 103 and the second electrical connection points 104 are connected in a one-to-one correspondence.

[0051] Lead electrode 1 refers to a conductive element in an electronic device used to connect an internal power supply terminal to an external circuit. Examples include FPC (Flexible Printed Circuit), PCB (Printed Circuit Board), and connectors. The power supply terminal refers to the internal circuitry or electronic module that needs to receive electrical signal input; it can be various functional units such as sensors, displays, processors, camera modules, and radio frequency modules. External circuitry refers to the circuit system outside of the internal modules of the electronic device, including but not limited to the motherboard, power supply unit, and control circuitry.

[0052] The first end 101 is the end that leads out the electrode 1 and is used to connect to the end to be powered, serving as the interface between the lead-out electrode 1 and the end to be powered. The first end 101 is provided with multiple first electrical connection points 103. Each first electrical connection point 103 can be understood as a specific electrical contact position located on the first end 101. Each first electrical connection point 103 is a conductive element, such as a metal pad, pin, or contact, responsible for transmitting one electrical signal. Furthermore, the multiple first electrical connection points 103 can be arranged in a certain layout to form an interface array. As an example, if three electronic modules (such as a sensor, a display screen, and a processor) all have signal transmission requirements, then three first electrical connection points 103 can be provided on the first end 101, each corresponding to one of the three electronic modules.

[0053] The second end 102 is the other end of the lead-out electrode 1 and is used to connect to an external circuit, serving as the interface between the lead-out electrode 1 and the external circuit. Multiple second electrical connection points 104 are provided on the second end 102. Each second electrical connection point 104 can be understood as a specific electrical contact position located on the second end 102. Each second electrical connection point 104 is a conductive element, such as a metal pad, pin, or contact, responsible for transmitting one electrical signal. Furthermore, multiple second electrical connection points 104 can be arranged in a certain layout to form an interface array. In addition, circuitry can be integrated or printed on the lead-out electrode 1 to ensure a one-to-one electrical connection between the first electrical connection point 103 and the second electrical connection point 104, thereby facilitating the transmission or control of electrical signals from various electronic modules.

[0054] During assembly, different terminals to be powered can be connected one-to-one with multiple first electrical connection points 103 on the first end 101 of the lead electrode 1, and external circuits can be connected to multiple second electrical connection points 104 on the second end 102 of the lead electrode 1. In this way, electrical signals can be transmitted from the external circuit to the terminals to be powered via the second electrical connection points 104 and the first electrical connection points 103, or the electrical signals can be transmitted from the terminals to be powered via the first electrical connection points 103 and the second electrical connection points 104 to the external circuit, thereby achieving accurate transmission of electrical signals.

[0055] Therefore, the embodiments of this application can simultaneously connect multiple power supply terminals through an integrated lead electrode 1, realizing the integrated transmission of multiple signals. This allows multiple power supply terminals and external circuits to share a single lead electrode interface, thereby reducing the number of traces, simplifying wiring, improving space utilization, and effectively solving the problems of complex wiring and large space occupation caused by multiple independent lead electrodes in traditional electronic devices.

[0056] The lead electrode 1 provided in this application embodiment can be applied to various electronic devices, such as displays, sensor arrays (e.g., temperature, humidity, pressure sensors), wearable devices (e.g., smartwatches, health trackers), solar panels, electrochromic films, etc. The electrochromic component provided in this application will be described below.

[0057] In some embodiments, refer to Figure 1 and Figure 2 As shown, this application also provides an electrochromic component, including: a membrane body 2 and an output electrode 1 as described in the above embodiment. The membrane body 2 includes a plurality of color-changing regions 201. The output electrode 1 includes a first output electrode 105 and a second output electrode 106. A plurality of first electrical connection points 103 on the first output electrode 105 are respectively connected to the positive electrodes of the plurality of color-changing regions 201, and a plurality of first electrical connection points 103 on the second output electrode 106 are respectively connected to the negative electrodes of the plurality of color-changing regions 201.

[0058] The diaphragm body 2 is the element that carries the electrochromic function and may include one or more layers of electrochromic materials. These materials have electrochromic properties, meaning their color or transparency can change according to the applied voltage. Furthermore, the diaphragm body 2 is divided into multiple regions, each of which is an independent color-changing unit, i.e., a color-changing region 201. The first lead electrode 105 and the second lead electrode 106 are elements used to provide electrical signal input to these color-changing regions 201. The first lead electrode 105 and the second lead electrode 106 can be connected to an external controller. Through the first lead electrode 105 and the second lead electrode 106, the controller's power supply and / or control signals can be transmitted to the corresponding color-changing regions 201 via the first electrical connection point 103 and the second electrical connection point 104, thereby precisely controlling the voltage applied to each color-changing region 201, causing different regions to display different color or transparency states, thus achieving changes in patterns, information, or visual effects. For example, in the application scenario of smart windows, the membrane body 2 can be an electrochromic glass, and users can adjust the amount of light entering the room by adjusting the transparency of different areas through the controller; in the application scenario of displays, the membrane body 2 can be a screen used to display dynamic images or text, and users can adjust the display and brightness of the screen by adjusting the transparency of different areas through the controller.

[0059] Multiple first electrical connection points 103 on the first lead electrode 105 are electrically connected one-to-one to the positive terminals of different color-changing regions 201 of the diaphragm body 2, providing positive electrical signals to each color-changing region 201. Similarly, multiple first electrical connection points 103 on the second lead electrode 106 are electrically connected one-to-one to the negative terminals of different color-changing regions 201 of the diaphragm body 2, providing negative electrical signals to each color-changing region 201, thus forming a complete circuit. This ensures that each color-changing region 201 receives the correct electrical signal, thereby independently adjusting its own color or transparency state.

[0060] For example, such as Figure 2 and Figure 3 As shown, the diaphragm body 2 includes three independent color-changing regions (labeled A, B, and C). The first lead-out electrode 105 has three first electrical connection points (labeled P1, P2, and P3) and three second electrical connection points (labeled P11, P12, and P13). P1 is connected to the positive terminal of color-changing region A; P2 is connected to the positive terminal of color-changing region B; and P3 is connected to the positive terminal of color-changing region C. P11, P12, and P13 are respectively connected to an external power supply circuit and / or a control circuit. Figure 4 As shown, the second lead electrode 106 is provided with three first electrical connection points (marked as Q1, Q2, Q3) and three second electrical connection points (marked as Q11, Q12, Q13). Q1 is connected to the negative terminal of color-changing area A; Q2 is connected to the negative terminal of color-changing area B; Q3 is connected to the negative terminal of color-changing area C; and Q11, Q12, and Q13 are respectively connected to the external power supply circuit and / or control circuit to form a complete loop.

[0061] When the color of a certain color-changing area is changed, an appropriate voltage can be applied through the corresponding electrical connection point on the first lead electrode 105. For example, if the color of color-changing area B is to be changed, a voltage can be applied to the positive terminal of color-changing area B through P2, and Q2 on the second lead electrode 106 is connected to the negative terminal of color-changing area B to form a closed circuit.

[0062] It is understood that this application can achieve independent control of all color-changing regions 201 on the same membrane body 2 using only a pair of lead electrodes 1, without the need to configure a pair of lead electrodes 1 for each color-changing region 201. This not only simplifies the overall design but also reduces the number of required wires, which is beneficial for the miniaturization and high-efficiency operation of the device.

[0063] In some embodiments, refer to Figures 2 to 5 As shown, the first end 101 of the first lead electrode 105 is a contoured structure of the edge of the diaphragm body 2; and / or, the first end 101 of the second lead electrode 106 is a contoured structure of the edge of the diaphragm body 2.

[0064] The first end 101 of the first lead electrode 105 and / or the second lead electrode 106 is configured to match the edge contour of the diaphragm body 2, i.e., "conformal". For example, if the edge of the diaphragm body 2 is curved, the first end 101 of the lead electrode is also configured to be the same curved shape.

[0065] This design allows the first end 101 of the lead electrode to be tightly attached to the edge of the diaphragm body 2, enabling the first electrical connection point 103 on the first end 101 to be easily connected to the positive and negative poles of the strain gauge region 201 on the diaphragm body 2. This avoids unstable or failed electrical signal transmission due to gaps, thus achieving a highly efficient and reliable electrical connection. Furthermore, the tight attachment also improves the overall aesthetics.

[0066] In one example, such as Figure 2 As shown, multiple color-changing areas 201 are arranged in sequence; the first end 101 of the first lead electrode 105 is sequentially attached to the local edge region of each color-changing area 201, and / or, the first end 101 of the second lead electrode 106 is sequentially attached to the local edge region of each color-changing area 201.

[0067] The first end 101 of the first lead electrode 105 is configured to be sequentially attached to the local edge region of the side of each color-changing area 201. This facilitates direct electrical connection of the first electrical connection point 103 on the first end 101 to the positive electrode of each color-changing area 201. Similarly, the first end 101 of the second lead electrode 106 is also sequentially attached to the local edge region of the side of each color-changing area 201, facilitating direct electrical connection of the first electrical connection point 103 on the first end 101 to the negative electrode of the color-changing area 201. Because of this direct attachment method, conductive components such as wires and copper foil are eliminated, simplifying the wiring and assembly process and making the entire structure more compact.

[0068] In another example, such as Figure 5 As shown, unlike the example above, in this example, the first end 101 of the first lead electrode 105 and / or the second lead electrode 106 is not attached to each color-changing area 201. For example, it can be attached to the edge of one or two color-changing areas 201. The first electrical connection point 103 on the first end 101 can be directly connected to the positive and negative poles of the attached color-changing area 201, while it can be electrically connected to the unattached color-changing area 201 through conductive parts such as wires and copper foil.

[0069] Therefore, the connection between the first end 101 of the lead electrode 1 and the color-changing area 201 in this embodiment is flexible and diverse, which can meet different design requirements.

[0070] In some embodiments, refer to Figure 6 and Figure 7As shown, the membrane body 2 includes a first base layer 202, a first conductive layer 203, an electrochromic layer 204, a second conductive layer 205, and a second base layer 206 arranged sequentially. The membrane body 2 has a plurality of first grooves 207 and a plurality of second grooves 208. The first grooves 207 penetrate the first base layer 202, the first conductive layer 203, and the electrochromic layer 204 to form a positive electrode, and the second grooves 208 penetrate the second base layer 206, the second conductive layer 205, and the electrochromic layer 204 to form a negative electrode.

[0071] The first substrate layer 202 and the second substrate layer 206 serve as the basic support layers for the entire membrane body 2. Both are transparent substrates. The "transparent substrate" is an optically transparent material, specifically a flexible substrate material, such as polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymers, or cellulose triacetate. The first substrate layer 202 and the second substrate layer 206 can also be made of glass substrates.

[0072] Both the first conductive layer 203 and the second conductive layer 205 are transparent conductive layers. The material of the "transparent conductive layer" can be any transparent conductive material well known to those skilled in the art, such as indium-tin oxide (ITO), aluminum zinc oxide (AZO), fluorine-doped tin oxide (FTO), silver nanowires, graphene, carbon nanotubes, metal meshes, or silver nanoparticles.

[0073] The electrochromic layer 204 is a sheet composed of one or more layers of gel-state or solid materials, such as polymer-dispersed liquid crystal (PDLC) layers, suspended particle devices (SPD) layers, and electrochromic (EC) layers. For electrochromic (EC) type electrochromic layers, they may include a color-changing material layer, an electrolyte layer, and an ion storage layer stacked sequentially. The materials of the color-changing material layer, electrolyte layer, and ion storage layer can be those found in the prior art, and this application does not impose any special limitations on them.

[0074] The first groove 207 penetrates the first substrate layer 202, the first conductive layer 203, and the electrochromic layer 204, exposing a portion of the second conductive layer 205 as a positive electrode. This facilitates the introduction of external power or control signals into the second conductive layer 205, thereby driving the electrochromic layer 204 to change color. The second groove 208 penetrates the second substrate layer 206, the second conductive layer 205, and the electrochromic layer 204, exposing a portion of the first conductive layer 203 as a negative electrode, forming part of a closed circuit. This allows current to flow out from the first conductive layer 203, completing the electrochemical cycle. Furthermore, a first busbar 209 can be disposed on the side of the first substrate layer 202 away from the first conductive layer 203, and the first busbar 209 is electrically connected to the second conductive layer 205 through the first groove 207. A second busbar 210 can also be disposed on the side of the second substrate layer 206 away from the second conductive layer 205, and the second busbar 210 is electrically connected to the first conductive layer 203 through the second groove 208. That is, busbars are provided on both sides of the diaphragm body 2 in the thickness direction, thereby forming a structure connecting multiple electrodes at the edge of the diaphragm body 2 and accelerating the color change speed of the diaphragm body 2. The first busbar 209 and the second busbar 210 can be made of conductive materials well known to those skilled in the art, such as at least one of conductive silver paste, conductive copper paste, conductive carbon paste, nano silver conductive ink, copper foil, copper wire and conductive film.

[0075] Understandably, the groove design directly exposes the corresponding conductive layer, allowing the lead-out electrodes or busbars to be directly attached to these exposed areas without the need for additional soldering or crimping of wires. This greatly simplifies the manufacturing process and electrical connections, saves space required for additional wiring, and is beneficial for the miniaturization of equipment.

[0076] Furthermore, multiple first grooves 207 are provided on the front edge of the membrane body 2, and multiple second grooves 208 are provided on the reverse edge of the membrane body 2. Then, through a cutting process, the conductive layer and the electrochromic layer 204 can be cut along the tangent between adjacent color-changing areas 201, thus achieving a multi-zone design. For example, the original structure of the membrane body 2 includes a first base layer 202, a first conductive layer 203, an electrochromic layer 204, a second conductive layer 205, and a second base layer 206. Through laser cutting, the first conductive layer 203, the electrochromic layer 204, and the second conductive layer 205 can be cut, leaving the first base layer 202 and the second base layer 206. With this design, this application does not need to process the electrodes of each color-changing area 201 of the membrane body 2 separately; only one electrode processing is needed around the edge of the membrane to complete the electrode processing of each color-changing area 201, effectively simplifying the electrode processing process. Furthermore, the sectional tangent can be hidden inside the base layer, making it difficult to observe, thereby improving the overall aesthetics.

[0077] It should be noted that the positive electrode is provided on the front edge of each color-changing area 201 on the diaphragm body 2, and the negative electrode is provided on the back edge. The positive and negative electrodes refer to the electrical connection points provided on the device for connection to the outside. For example, the positive electrode may include any area on the first busbar 209, or the positive electrode (i.e., the portion of the second conductive layer 205 exposed at the bottom of the first groove 207), etc. Similarly, the negative electrode may include any area on the second busbar 210, or the negative electrode (i.e., the portion of the first conductive layer 203 exposed at the bottom of the second groove 208), etc.

[0078] In some embodiments, refer to Figure 7 As shown, the edge of the membrane body 2 is provided with multiple positive electrodes and multiple negative electrodes; the electrochromic assembly also includes multiple first busbars 209 and multiple second busbars 210, with multiple positive electrodes of the same color-changing area 201 connected through the first busbars 209; and multiple negative electrodes of the same color-changing area 201 connected through the second busbars 210.

[0079] Multiple positive electrodes (i.e., the portion of the second conductive layer 205 exposed at the bottom of the first groove 207) and negative electrodes (i.e., the portion of the first conductive layer 203 exposed at the bottom of the second groove 208) are disposed along the edge of the diaphragm body 2. These electrodes are responsible for receiving externally applied voltage signals and transmitting them to the corresponding color-changing areas 201. The entire electrode layout along the edge of the diaphragm body 2 is n-shaped, as shown below. Figure 2 As shown, this design achieves a color-changing effect from the periphery towards the center. The first busbar 209 can be made of a material with good conductivity and mechanical strength (such as copper foil, aluminum foil, etc.) and is used to connect all the positive electrodes within the same color-changing area 201, forming a unified positive input terminal. The second busbar 210 can be made of a material with good conductivity and mechanical strength (such as copper foil, aluminum foil, etc.) and is used to connect all the negative electrodes within the same color-changing area 201, forming a unified negative output terminal. When a positive voltage is applied to the first busbar 209, the current is evenly distributed to each positive electrode through the busbar, thereby affecting the color or transparency change of the entire color-changing area 201. Similarly, the second busbar 210 is responsible for connecting the negative electrodes together, ensuring that the current can flow out smoothly.

[0080] Understandably, using a busbar can significantly reduce the number of connection points required compared to making separate lead-out electrode connections for each individual positive and negative electrode. For example, if a color-changing area 201 has ten positive electrodes, only one first busbar 209 is needed to connect all the positive electrodes, instead of ten separate wires.

[0081] Therefore, by introducing busbars, this embodiment of the application can reduce the number of electrical connection points, making the overall circuit layout simpler, reducing wiring complexity, and minimizing space occupation. Furthermore, centralized management of current input / output through busbars helps achieve uniform current distribution throughout the entire color-changing area 201, reducing problems such as localized overheating or uneven color distribution.

[0082] In some embodiments, refer to Figure 1 and Figure 2 As shown, a plurality of first electrical connection points 103 on the first lead electrode 105 are respectively connected to the positive electrodes of a plurality of color-changing regions 201, including one or more of the following combinations: the first electrical connection point 103 of the first lead electrode 105 is connected to the positive electrode of the corresponding color-changing region 201, or the first electrical connection point 103 of the first lead electrode 105 is connected to the first busbar 209 of the corresponding color-changing region 201, or the first electrical connection point 103 of the first lead electrode 105 and the first busbar 209 of the corresponding color-changing region 201 are connected through a first electrical connector 211.

[0083] Multiple first electrical connection points 103 on the first lead electrode 105 can be directly or indirectly connected to the positive electrode of the corresponding strain color region 201. Several examples are given below for general description.

[0084] For example, such as Figure 3 and Figure 5 As shown, the diaphragm body 2 includes three independent color-changing regions (labeled A, B, and C). The first lead-out electrode 105 has three first electrical connection points (labeled P1, P2, and P3). P1 is directly connected to the positive electrode of color-changing region A (i.e., the portion of the second conductive layer 205 exposed at the bottom of the first groove 207); P2 is directly connected to the positive electrode of color-changing region B; and P3 is directly connected to the positive electrode of color-changing region C. Each first electrical connection point can be connected to the positive electrode by welding or by conductive adhesive.

[0085] For example, such as Figure 3 , Figure 5 and Figure 7 As shown, the diaphragm body 2 includes three independent color-changing regions (labeled A, B, and C). The first lead-out electrode 105 is provided with three first electrical connection points (labeled P1, P2, and P3). P1, P2, and P3 are respectively connected to the first busbars 209 corresponding to the color-changing regions A, B, and C. The connection positions can be on the outside or inside of the first busbars 209. The inside position can specifically include the position on the first substrate layer 202 or the position on the second conductive layer 205 exposed at the bottom of the first groove 207. In this way, electrical signals can be transmitted to the corresponding entire color-changing region through the busbars, which greatly reduces the number of external connection points, improves structural simplicity, and saves space.

[0086] For example, such as Figure 3 and Figure 8 As shown, the diaphragm body 2 includes three independent color-changing zones (labeled A, B, and C). The first lead-out electrode 105 has three first electrical connection points (labeled P1, P2, and P3). P1 is connected to the first busbar 209 of color-changing zone A; P2 is directly connected to the positive electrode of color-changing zone B (i.e., the portion of the second conductive layer 205 exposed at the bottom of the first groove 207); and P3 is connected to the first electrical connector 211 of color-changing zone C, which is connected to its first busbar 209. The first electrical connector 211 can be a wire, conductive adhesive, metal sheet, plug-in terminal, connector, etc. That is, P3 of the first lead-out electrode 105 is connected to the positive electrode of the corresponding color-changing zone C via the first electrical connector 211 and the first busbar 209.

[0087] Therefore, the embodiments of this application provide multiple connection methods between the first lead electrode 105 and the color-changing area 201, thereby improving assembly flexibility.

[0088] In some embodiments, refer to Figure 8 As shown, the first busbar 209 and the first electrical connector 211 corresponding to the same color-changing area are integrally formed.

[0089] The first busbar 209 can be made of a material with good conductivity (such as copper foil, aluminum foil, etc.). A portion of it is used to gather multiple positive electrodes in the color-changing area 201. A portion of it can also be designed as a stretchable and flexible "extension" (i.e., the first electrical connector 211) for direct connection to the first electrical connection point 103 on the first lead electrode 105.

[0090] Therefore, in this embodiment, multiple positive electrodes within the same color-changing area 201 can be uniformly connected via the first busbar 209 to achieve balanced voltage distribution. Furthermore, the integrally formed first electrical connector 211 directly connects to the external first lead electrode 105, functioning as a charging wire. This design eliminates the need for additional wires, solder joints, or connectors, reducing the number of components, simplifying the structure and process, and minimizing potential failure points due to wire breakage or poor contact, thus improving long-term stability. Additionally, the integral design avoids the space occupied by traditional wiring, facilitating miniaturization and thinner design of the device.

[0091] In some embodiments, refer to Figure 8 As shown, a first insulating layer 212 is provided between the first busbar 209 and its adjacent first electrical connector 211.

[0092] The specific type of the first insulating layer 212 in this embodiment is not particularly limited, as long as it can serve an insulating function. For example, it can be insulating tape, polyimide film, polyester film, epoxy resin coating, silicone insulating film, alumina ceramic layer, etc. By providing the first insulating layer 212 between the first busbar 209 and its adjacent first electrical connector 211, this embodiment can prevent direct contact between the two conductive components, avoid short circuits caused by accidental contact, improve safety, and the insulating layer can also provide a certain buffering and supporting effect, extending the device life.

[0093] In some embodiments, refer to Figure 1 and Figure 2 As shown, multiple first electrical connection points 103 on the second lead electrode 106 are respectively connected to the negative electrodes of multiple color-changing regions 201, including one or more of the following combinations: the first electrical connection point 103 of the second lead electrode 106 is connected to the negative electrode of the corresponding color-changing region 201, or the first electrical connection point 103 of the second lead electrode 106 is connected to the second busbar 210 of the corresponding color-changing region 201, or the first electrical connection point 103 of the second lead electrode 106 is connected to the second busbar 210 of the corresponding color-changing region 201 through the second electrical connector 213.

[0094] Multiple first electrical connection points 103 on the second lead electrode 106 can be connected to the negative electrode of the corresponding strain color region 201 in a direct or indirect manner. A few examples are given below for general description.

[0095] For example, such as Figure 4 and Figure 5 As shown, the diaphragm body 2 includes three independent color-changing regions (labeled A, B, and C). The second lead electrode 106 has three first electrical connection points (labeled Q1, Q2, and Q3). Q1 is directly connected to the negative electrode of color-changing region A (i.e., the portion of the first conductive layer 203 exposed at the bottom of the second groove 208); Q2 is directly connected to the negative electrode of color-changing region B; and Q3 is directly connected to the negative electrode of color-changing region C. Each first electrical connection point can be connected to the negative electrode by soldering or by using conductive adhesive.

[0096] For example, such as Figure 4 , Figure 5 and Figure 7As shown, the diaphragm body 2 includes three independent color-changing regions (labeled A, B, and C). The second lead electrode 106 is provided with three first electrical connection points (labeled Q1, Q2, and Q3). Q1, Q2, and Q3 are respectively connected to the second busbars 210 corresponding to the color-changing regions A, B, and C. The connection positions can be on the outside or inside of the second busbars 210. The inside position can specifically include the position on the second substrate layer 206 or the position on the part of the first conductive layer 203 exposed at the bottom of the second groove 208. In this way, electrical signals can be transmitted to the corresponding entire color-changing region through the busbars, which greatly reduces the number of external connection points, improves structural simplicity, and saves space.

[0097] For example, such as Figure 4 and Figure 9 As shown, the diaphragm body 2 includes three independent color-changing zones (labeled A, B, and C). The second lead electrode 106 is provided with three first electrical connection points (labeled Q1, Q2, and Q3). Q1 is connected to the second busbar 210 of color-changing zone A; Q2 is connected to the second electrical connector 213 of color-changing zone B, which is connected to its second busbar 210. The second electrical connector 213 can be a wire, conductive adhesive, metal sheet, plug-in terminal, connector, etc. That is, Q2 of the second lead electrode 106 is connected to the negative electrode of the corresponding color-changing zone B through the second electrical connector 213 and the second busbar 210; Q3 is directly connected to the negative electrode of color-changing zone C.

[0098] Therefore, this application provides multiple connection methods between the second lead electrode 106 and the color-changing area 201, thereby improving assembly flexibility.

[0099] In some embodiments, refer to Figure 9 As shown, the second busbar 210 and the second electrical connector 213 corresponding to the same color-changing area are integrally formed.

[0100] The second busbar 210 can be made of a material with good conductivity (such as copper foil, aluminum foil, etc.). A portion of it is used to gather multiple negative electrodes in the color-changing area 201. A portion of it can also be designed as a stretchable and flexible "extension" (i.e., the second electrical connector 213) for direct connection to the first electrical connection point 103 on the second lead electrode 106.

[0101] Therefore, in this embodiment, multiple negative electrodes within the same color-changing area 201 can be connected uniformly through the second busbar 210 to achieve balanced voltage distribution. Furthermore, the integrally formed second electrical connector 213 directly connects to the external second lead electrode 106, functioning as a charging wire. This design eliminates the need for additional wires, solder joints, or connectors, reducing the number of components, simplifying the structure and process, and minimizing potential failure points due to wire breakage or poor contact, thus improving long-term stability. In addition, the integral design avoids the space occupied by traditional wiring, facilitating miniaturization and thinner design of the device.

[0102] In some embodiments, refer to Figure 9 As shown, a second insulating layer 214 is provided between the second busbar 210 and its adjacent second electrical connector 213.

[0103] The specific type of the second insulating layer 214 in this embodiment is not particularly limited, as long as it can serve an insulating function. For example, it can be insulating tape, polyimide film, polyester film, epoxy resin coating, silicone insulating film, alumina ceramic layer, etc. By providing a second insulating layer 214 between the second busbar 210 and its adjacent second electrical connector 213, this embodiment can prevent direct contact between the two conductive components, avoiding short circuits caused by accidental contact, improving safety, and the insulating layer can also provide some buffering and support, extending the device's lifespan.

[0104] The color-changing device provided in the embodiments of this application will be described below.

[0105] In some embodiments, refer to Figure 10 As shown, this application also provides a color-changing device 3, including: the lead-out electrode 1 of the above embodiments or the electrochromic component of the above embodiments. The specific type of the color-changing device 3 in this application is not particularly limited; for example, it can be a display screen, glass, etc. The glass can include automotive windshields, side windows, and sunroofs, architectural glass, etc.

[0106] Since the color-changing device 3 provided in this application includes the lead-out electrode 1 of the above embodiments or the electrochromic component of the above embodiments, it has all the technical effects of the lead-out electrode 1 of the above embodiments or the electrochromic component of the above embodiments, which will not be elaborated here.

[0107] As an example, such as Figure 10As shown, the color-changing device 3 can be a windshield, including a glass body 301 and an electrochromic component as described in the above embodiment. The diaphragm body 2 of the electrochromic component is sandwiched inside the glass body 301. The first end 101 of the first lead electrode 105 and the first end 101 of the second lead electrode 106 are located inside the glass body 301 to facilitate electrical connection with each color-changing area 201 of the diaphragm body 2. The second end 102 of the first lead electrode 105 and the second end 102 of the second lead electrode 106 are located outside the glass body 301 to facilitate connection with an external power supply circuit and / or control circuit, thereby realizing the electrochromic function. Multiple electrochromic components can be used to form multiple electrochromic zones on the glass body 301. Some of these components can be located in the upper area of ​​the glass body 301 to change the glass's transparency via electrochromic adjustment, thus providing sun shading and preventing glare from affecting driving. The first lead electrode 105 and the second lead electrode 106 are located in the mounting area between adjacent upper electrochromic zones, resulting in a compact structure and small footprint. Additionally, some electrochromic components can be located in the lower area of ​​the glass body 301 to change the glass's transparency via electrochromic adjustment, enabling a head-up display (HUD). A HUD, also known as a head-up display system, is a driver-centric, blind-operated, multi-functional instrument panel. Its function is to project important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see this information without looking down or turning their head, thereby improving driving comfort. Therefore, by applying the electrochromic component to the windshield, the requirements for sun shading and head-up display can be met, thereby improving the user experience.
