Description

Technical Field

[0001] This application relates to the field of dimming film technology, and more particularly to a wiring structure, dimming film, glass assembly, and vehicle. Background Technology

[0002] A dimming PDLC film is made by coating a polymer-dispersed liquid crystal layer between two ITO films, and then polymerizing the polymer through photocuring or thermal curing. During this process, liquid crystal precipitates from the polymer, forming micron-sized droplets that are uniformly dispersed within the polymer network. Under the influence of an electric field, the liquid crystals undergo reorientation. When the liquid crystal molecules are aligned perpendicular to the film surface, the film becomes transparent; when randomly arranged, the film appears hazy. Therefore, by applying a voltage to ITO1 and ITO2, the liquid crystal molecules in the liquid crystal layer sandwiched between ITO1 and ITO2 are changed from an opaque, disordered distribution to a translucent, ordered arrangement. Light can then pass through the gaps between the liquid crystal molecules on one side of the PDLC film to the other, thus achieving the dimming function of the PDLC film.

[0003] The current method for fabricating electrodes for PDLC films is to attach FPCs.

[0004] Because FPCs have independent pads, they occupy space on the film plane, increasing the black border of the film and reducing the display area. Utility Model Content

[0062] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0063] This application provides a wiring structure 10, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of a wiring structure 10 provided in an exemplary embodiment of this application; Figure 2 yes Figure 1 The wiring structure of the drive axle 10 is shown in the AA cross-sectional view.

[0064] The wiring structure 10 is applied in a dimming diaphragm 100. The wiring structure 10 includes a connecting line 11, which includes a first conductor 111 and a cover film 112.

[0065] The first conductor 111 is made of a conductive material, such as copper. The cover film 112 is an insulating film that covers the first conductor 111 to prevent improper contact between the first conductor 111 and other components. The cover film 112 has a first opening 113, through which the first conductor 111 can be exposed to make electrical contact with other electronic components.

[0066] When the wiring structure 10 is applied to the dimming diaphragm 100, the first conductor 111 makes electrical contact with the first plate electrode 20 of the dimming diaphragm 100 through the first opening 113 to supply power to the first plate electrode 20.

[0067] This application addresses the problem of the first conductor 111 being exposed by directly opening a first opening 113 on the cover film 112 of the connecting line 11. This allows the first conductor 111 to make direct electrical contact with the first plate electrode 20 through the first opening 113 when the wiring structure 10 is placed on the first plate electrode 20 of the dimming film 100. This saves space on the film plane occupied by the connecting line 11, reduces the black border of the film, and increases the display area. It at least partially solves the technical problem in the prior art where the wires occupy space on the film plane due to the independent pads of the FPC, resulting in increased black borders and reduced display area.

[0068] When the first plate electrode 20 includes N partition electrodes 21, N is an integer greater than or equal to 1. Correspondingly, the connecting line 11 includes M first conductors 111, M is an integer greater than or equal to 1. M and N can be equal or unequal. For example, when M is greater than N, when the connecting line 11 is electrically connected to the first plate electrode 20, one or more first conductors 111 can be unconnected to the partition electrodes 21. It can be understood that M can also be less than N. When the connecting line 11 is electrically connected to the first plate electrode 20, one or more partition electrodes 21 can be unconnected to the first conductors 111, that is, one or more partition electrodes 21 are not energized. Similarly, one or more partition electrodes 21 can be simultaneously unconnected to the first conductors 111, and one or more first conductors 111 can be unconnected to the partition electrodes 21.

[0069] The connecting line 11 includes M first conductors 111, and the covering film 112 may have P first openings 113. P is an integer greater than or equal to 1. M and P may be equal or not equal. For example, some first conductors 111 may not have a corresponding first opening 113, that is, they are not in electrical contact with the first plate electrode 20; some first conductors 111 may have two or more first openings 113, that is, they are in electrical contact with the corresponding partition electrode 21 through two or more first openings 113.

[0070] When the connecting line 11 includes M first conductors 111 and P first openings 113, one first conductor 111 makes electrical contact with one of the N partition electrodes 21 of the first plate electrode 20 through at least one first opening 113, including at least the following cases.

[0071] First, M and N are equal, meaning the number of partition electrodes 21 and the number of first conductors 111 correspond. One first conductor 111 is electrically connected to one partition electrode 21, that is, each partition electrode 21 is electrically connected to one first conductor 111, and each first conductor 111 is connected to one partition electrode 21. In other words, each first conductor 111 and each partition electrode 21 are used, thereby avoiding the situation where some partition electrodes 21 or some first conductors 111 are idle, which is not conducive to the utilization of space.

[0072] Second, M, N and P are equal, that is, the number of partition electrodes 21, first openings 113 and first conductors 111 correspond. One of the M first conductors 111 makes electrical contact with one of the N partition electrodes 21 through one of the P first openings 113, which is a one-to-one correspondence.

[0073] Third, there are partition electrodes 21 that are not connected to the first conductor 111, or / and there are first conductors 111 that are not connected to partition electrodes 21. M and N can be equal, M can be greater than N, or it can be less than N. For example, the partition electrodes 21 on the edge of the first plate electrode 20 are not connected to the first conductor 111, the number of first conductors 111 in the connecting line 11 is increased, or they are spares, so that there are first conductors 111 that are not connected to partition electrodes 21.

[0074] Fourth, there are first conductors 111 that do not have a corresponding first opening 113, or / and there are first conductors 111 that have two or more corresponding first openings 113. For example, a first conductor 111 that is not connected to the partition electrode 21 does not have a corresponding first opening 113, while a first conductor 111 that is connected to the partition electrode 21 has two or more first openings 113, and the first conductor 111 makes electrical contact with the corresponding partition electrode 21 through the two or more first openings 113.

[0075] Specifically, M, N, and P can be set as needed, and no specific limitations are made here. When M is greater than or equal to 2, that is, when there are more than or equal to 2 first conductors 111, the covering film 112 is also used to prevent improper contact between the first conductors 111.

[0076] In some embodiments, the connecting line 11 is flat. Making the connecting line 11 flat reduces space occupation and makes wiring simpler. In addition, flat connecting lines are less prone to scattering, misalignment, or knotting.

[0077] In some implementations, the connecting line 11 is flexible and can be bent and folded. By making the connecting line 11 flexible, spatial adaptability can be improved, allowing for flexible wiring in narrow or complex spaces to adapt to special scenarios such as curved surfaces and corners, while reducing space occupation. After folding, it can be neatly arranged along a preset path to reduce the risk of interference with other functional layers. In addition, it simplifies installation and maintenance.

[0078] Furthermore, the connecting line 11 is an FFC (Flexible Flat Cable), which is a type of flat cable made of flat and soft conductors and a very thin flexible film or paper film bonded together at high temperature, and can be bent and folded.

[0079] This application allows the first conductor 111 to contact the partition electrode 21 through the first opening 113 on the FFC. Since the FFC is relatively soft and the dimming film is relatively hard, the FFC is fully attached to the film and the whole is relatively flat, which is not easy to generate wavy lines. To a certain extent, it can extend the service life of the FFC and improve the overall stability of the dimming film. This solves the technical problem that when using FPC bonding, wavy lines are easily generated at the wiring position. The FPC being in a wavy state for a long time will increase the mechanical stress of the FPC, which may lead to the breakage or damage of the FPC in the long run.

[0080] In addition, FFC can be folded, and the circuit layout can be changed by different folding angles. Compared with FPC, which is not resistant to bending and can only form fixed circuits by etching, FFC is more flexible and can adapt to a variety of complex connection positions. FFC products of the same specification can be folded to fit a variety of different dimming films.

[0081] Furthermore, the manufacturing process of FPC is complex, requiring multiple steps such as coating, etching, exposure, and surface treatment, and it is composed of multiple layers, which leads to signal transmission delay and affects the performance of high-speed signal transmission. In contrast, the structure of FFC is much simpler, with only a first conductor 111 sandwiched between the upper and lower films. The simple structure gives it lower impedance and lower signal loss, and more stable electrical performance.

[0082] In some embodiments, the cover film 112 includes an upper film 114 and a lower film 115, with N first conductors 111 disposed between the upper film 114 and the lower film 115. By setting the upper film 114 and the lower film 115, the first conductors 111 are fixed and bonded, ensuring structural stability; in addition, it also has the functions of insulation and protection, isolating the wires to prevent short circuits and resisting the intrusion of moisture, dust, etc., to protect the first conductors 111.

[0083] Specifically, the covering film 112 includes an upper film 114 and a lower film 115. The first opening 113 can be made only on the upper film 114, or only on the lower film 115, or the first opening 113 can be made on both the upper film 114 and the lower film 115. The specific arrangement can be made as needed and is not limited here.

[0084] Furthermore, in order to ensure sufficient contact between the first conductor 111 and the partition electrode 21, specifically, the width b of the first opening 113 is greater than or equal to the width a of the first conductor 111. That is, the width direction of the first conductor 111 can be fully exposed through the first opening 113, so that the first conductor 111 can make sufficient contact with the partition electrode 21 through the first opening 113.

[0085] Furthermore, to facilitate electrical connections between this wiring structure 10 and other electronic components, see [reference needed]. Figure 3 In this embodiment, the wiring structure 10 further includes a connector 12, on which N first conductors 111 are inserted. When it is necessary to electrically connect the wiring structure 10 with other electronic components, the connector 12 can be directly inserted into the other electronic components to complete the connection, which improves the convenience of connection.

[0086] In other embodiments, the connecting line 11 may further include a conductor (not shown), one end of which is fixed to the connector 12, and the other end is electrically connected to the first conductor 111. That is, a conductor is provided between the connector 12 and each first conductor 111, connecting the first conductor 111 to the connector 12. By providing the conductor, connections of different distances can be accommodated.

[0087] This application also provides a dimming film 100, such as Figure 3 and Figure 4 As shown, the dimming diaphragm 100 includes a first flat plate electrode 20 and the aforementioned wiring structure 10. The wiring structure 10 is disposed on the first flat plate electrode 20, and the first conductor 111 is in electrical contact with the first flat plate electrode 20 through the first opening 113.

[0088] The dimming diaphragm 100 has all the beneficial effects of the aforementioned wiring structure 10, which will not be repeated here.

[0089] Specifically, the dimming film 100 further includes a second flat plate electrode 30, a dimming layer 40, and two transparent substrates 50. The dimming layer 40 is disposed between the first flat plate electrode 20 and the second flat plate electrode 30. The two transparent substrates 50 are located on both sides, and the first flat plate electrode 20, the dimming layer 40, and the second flat plate electrode 30 are fixed between the two transparent substrates 50.

[0090] Specifically, the first plate electrode 20 and the second plate electrode 30 are ITO, or indium tin oxide, a metal oxide thin film material with high transparency and good conductivity. It is usually deposited as an electrode layer on the transparent substrate of the dimming film. Its function is to transmit current through its conductivity. When a voltage is applied, it drives the liquid crystal molecules or electrochromic materials in the dimming film to change their arrangement state, thereby achieving the adjustment of light transmittance (such as switching from transparent to a fogged state).

[0091] The dimming layer 40 is specifically a liquid crystal. The liquid crystal in the dimming film 100 plays a core optical adjustment role, and its molecular arrangement can change with the electric field: when no voltage is applied, the liquid crystal molecules are arranged randomly, and light is scattered when it passes through, making the dimming film appear foggy (opaque); after voltage is applied, the liquid crystal molecules are arranged in an orderly manner under the influence of the electric field, and light can pass through smoothly, and the dimming film becomes transparent. This electrically controlled reversible change in molecular arrangement allows the dimming film to switch its transmittance in real time, realizing functions such as privacy protection and light adjustment. At the same time, the liquid crystal material has a fast response speed and low power consumption, which can ensure the stable operation of the dimming film in different scenarios. It is a key functional material for realizing the dynamic optical performance of the dimming film.

[0092] The transparent substrate 50 serves as a supporting framework in the dimming film, providing a physical foundation for each functional layer of the dimming film (such as ITO, liquid crystal, etc.), and ensuring the stability and flatness of each layer structure.

[0093] See also Figure 5 and Figure 6 In some embodiments, the first plate electrode 20 includes N partitioned electrodes 21; there are M first conductors 111 and P first openings 113, wherein one first conductor 111 is electrically contacted with one of the N partitioned electrodes 21 through at least one first opening 113. M, N, and P are integers greater than or equal to 1. The specific relationship between M, N, and P is described above and will not be repeated here. The first conductor 111 is electrically contacted with the first connection area 22 through the first opening 113 to facilitate control of the partitioned electrodes 21.

[0094] In some embodiments, each partition electrode 21 is provided with an exposed first connection area 22, and the first conductor 111 is electrically contacted with the first connection area 22 through the first opening 113. Specifically, the second plate electrode 30 and the transparent substrate 50 on which the second plate electrode 30 is located can be halved, and then the liquid crystal for dimming function can be erased to form the first connection area 22. By providing the first connection area 22 on the partition electrode 21, the position where the first conductor 111 is connected to the partition electrode 21 is defined.

[0095] In some embodiments, the first connection area 22 is located on one side of the partition electrode 21. By setting the first connection area 22 on one side of the first flat plate electrode 20, the edge space of the partition electrode 21 can be effectively utilized, avoiding the blocking of the light-transmitting area in the middle of the partition electrode 21 by the connecting line 11, thus ensuring the optical performance of the dimming film; at the same time, it facilitates neat wiring, reduces the risk of interference between the connecting line 11 and other functional layers, enhances structural reliability, and the edge connection method is easier to operate during installation and maintenance.

[0096] In some embodiments, the width L of the first connection area 22 is greater than or equal to 6.5 mm. Setting the width L of the first connection area 22 to be greater than or equal to 6.5 mm facilitates the arrangement of the connection line 11.

[0097] Furthermore, the width L of the first connection area 22 is greater than or equal to the width h of the connecting line 11. In this case, the connecting line 11 only includes the first conductor 111 and does not include the second conductor 131. By setting the width L of the first connection area 22 to be greater than or equal to the width h of the connecting line 11, the connecting line 11 can be arranged on the first connection area 22, avoiding the problem of unstable contact between the first conductor 111 and the first connection area 22 due to the edge of the connecting line 11 extending beyond the first connection area 22, thus improving the stability of the first conductor 111 and the first connection area 22.

[0098] To improve the stability of the electrical contact, in this embodiment, each first connection area 22 is provided with a first silver paste layer 23 that is in electrical contact with the first conductor 111. Since the conductivity of silver paste is hundreds of times that of ITO, the first silver paste layer 23 is provided on the first connection area 22 to ensure higher stability of the electrical contact and improve the contact stability between the first conductor 111 and the first connection area 22.

[0099] Furthermore, the width s of the first silver paste layer 23 is smaller than the width L of the first connection area 22. By setting the width s of the first silver paste layer 23 to be smaller than the width L of the first connection area 22, the current conduction range can be limited by reducing the conductive area of ​​the silver paste, and it can also be ensured that the silver paste is located in the non-transparent edge area where the first connection area 22 is located, thus avoiding blocking the middle transparent area and affecting the optical performance of the dimming film.

[0100] To further reduce the space occupied by the wiring of the dimming film 100, such as Figure 7 As shown, specifically, in some embodiments, the second plate electrode 30 is provided with a second connection region 31; the connection line 11 also includes a second conductor 131 that is electrically in contact with the second connection region 31, and the second conductor 131 is at least partially covered within the cover film 112.

[0101] In other words, the connecting line 11 also includes a second conductor 131 that is in electrical contact with the second plate electrode 30. This allows for a compact layout in space-constrained scenarios by utilizing existing line resources, improving system integration and avoiding structural complexity issues caused by rewiring.

[0102] Specifically, the first plate electrode 20 and the transparent substrate 50 on which the first plate electrode 20 is located can be half-cut, and then the liquid crystal with dimming function can be erased to form the second connection area 31.

[0103] Furthermore, the second conductor 131 is at least partially arranged in parallel with the first conductor 111. This arrangement of the second conductor 131 in parallel with the first conductor 111 further enhances system integration. The degree to which the second conductor 131 is arranged in parallel with the first conductor 111 is determined by the position of the second connection region 31.

[0104] Specifically, the second connection area 31 and the first connection area 22 are located on adjacent sides of the dimming film 100. For example, when the first connection area 22 is located on the left edge and the second connection area 31 is located on the lower edge, the second conductor 131 needs to be bent in order to make an electrical connection with the second connection area 31. In this case, the second conductor 131 is in a bent shape. It can be understood that when the first connection area is located on the left edge and the second connection area 31 is located on the upper edge, the second conductor 131 needs to be bent before it can be electrically connected with the second connection area 31. By bending the second conductor 131, the second conductor 131 can be connected to the second connection area 31 of the second plate electrode 30 after bending, so that the position of the second connection area 31 on the second plate electrode 30 can be selected more flexibly, avoiding the limitation of the position of the second connection area 31 on the second plate electrode 30.

[0105] Of course, in other embodiments, the second connection area 31 and the first connection area 22 may also be located on the same side of the dimming film 100. Correspondingly, the second conductor 131 is covered in the cover film 112 and arranged in parallel with the first conductor 111. The cover film 112 has a second opening (not shown in the figure), and the second conductor 131 makes electrical contact with the second plate electrode 30 through the second opening. At this time, the connecting line 11 is located between the first plate electrode 20 and the second plate electrode 30, and the liquid crystal between the second connecting area 31 and the first connecting area 22 has been erased. The first opening 113 is located on the surface opposite to the connecting line 11 and the first connecting area 22, and the second opening is located on the surface opposite to the connecting line 11 and the second connecting area 31. The first conductor 111 is electrically contacted with the first plate electrode 20 through the first opening 113, and the second conductor 131 is electrically contacted with the second plate electrode 30 through the second opening. This achieves the simultaneous presence of the first plate electrode 20 and the second plate electrode 30 on the same side of the dimming film 100, saving the space occupied by the connecting line, reducing the black border of the dimming film 100, and increasing the display area.

[0106] Specifically, the second connection region 31 is L-shaped, I-shaped, or U-shaped. For example, the second connection region 31 is located on both adjacent sides of the second plate electrode 30, which is L-shaped; of course, the second connection region 31 can also be located on only one side of the second plate electrode 30, such as the lower edge, which is I-shaped; understandably, the second connection region 31 can also be located on all three sides of the second plate electrode 30, which is U-shaped, and the specific shape can be set as needed. In this embodiment, the second connection region 31 is L-shaped and located at the adjacent two sides of the second plate electrode 30. By setting the second connection region 31 to L-shape and located at the adjacent two sides of the second plate electrode 30, the conductivity response speed is improved.

[0107] Furthermore, a second silver paste layer 32 is provided on the second connection region 31 to make electrical contact with the second conductor 131. Since the conductivity of silver paste is hundreds of times that of ITO, the second silver paste layer 32 is provided on the second connection region 31 to ensure higher stability of electrical contact and improve the contact stability between the second conductor 131 and the second connection region 31.
