Description

Technical Field

[0001] This application relates to the field of dimming technology, and in particular to a dimming device and dimming apparatus. Background Technology

[0002] With technological advancements, the demand for light and heat regulation is increasing, leading to greater attention being paid to dimming technology. Specifically, dimming technology refers to the technique where the optical properties of dimming materials change under the influence of an applied electric field, external light intensity, and other external factors. Typically, this results in reversible changes in the color and transparency of the dimming film containing the material. In recent years, dimming films have been widely used in energy-saving windows, automotive rearview mirrors, display films, mobile terminals, and other fields, demonstrating promising market prospects.

[0003] However, the dimming materials in dimming films are extremely sensitive to environmental moisture. Once exposed to moisture, they are prone to discoloration and failure, which accelerate the damage process and significantly shorten their lifespan. Therefore, ensuring the sealing of the film edges is crucial in the dimming film encapsulation process. The problem is that the edges of dimming devices are often irregularly shaped, making it difficult to achieve a complete seal using a single sealant, thus affecting the overall sealing performance of the film. Summary of the Invention

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a dimming device and dimming apparatus.

[0005] In a first aspect, this application provides a dimming device, comprising: A dimming film having a first surface and a second surface facing away from each other, and a side surface connecting the first surface and the second surface; Multiple colloids, each colloid having one end disposed on the edge region of the first surface and the other end extending through the side to the edge region of the second surface; In this case, two adjacent colloids partially overlap each other to form an overlapping portion.

[0006] In some embodiments, the dimming film has a first base layer, a first conductive layer, a dimming layer, a second conductive layer, and a second base layer stacked sequentially. The edge region of the dimming film has a plurality of notches, which penetrate the first conductive layer, the dimming layer, and the second conductive layer, and also penetrate at least one of the first base layer and the second base layer. The overlapping portion is located in the notch when projected along the stacking direction of the dimming film.

[0007] In some embodiments, the width of the notch is d, where d satisfies: 4mm ≤ d ≤ 12mm.

[0008] In some embodiments, the plurality of notches include a first notch and a second notch along the side of the dimming film, the width of the first notch being greater than the width of the second notch, and the overlapping portion being a projection along the stacking direction of the dimming film, the overlapping portion being located in the first notch.

[0009] In some embodiments, the plurality of colloids include a first colloid and a second colloid; the first colloid includes a first adhesive layer and a second adhesive layer, one end of the first adhesive layer is disposed on the first surface, one end of the second adhesive layer is disposed on the second surface, and the first adhesive layer and the second adhesive layer cooperate to cover the side of the dimming film and then become integral and extend in a direction away from the side. The second colloid includes a third adhesive layer and a fourth adhesive layer. One end of the third adhesive layer is disposed on the first surface, and one end of the fourth adhesive layer is disposed on the second surface. The third adhesive layer and the fourth adhesive layer cooperate to cover the side of the dimming film and then become a single unit and extend in a direction away from the side.

[0010] In some embodiments, the first colloid is disposed in the curved edge region of the dimming film, and the second colloid is disposed in the straight edge region of the dimming film; The first adhesive layer partially covers the third adhesive layer, and the second adhesive layer partially covers the fourth adhesive layer.

[0012] In some embodiments, the dimming device further includes a first busbar and a second busbar, wherein the first busbar is at least partially located within a first groove, and a first adhesive layer and a third adhesive layer cover the first busbar; The second busbar is at least partially located within the second groove; and the second adhesive layer and the fourth adhesive layer cover the second busbar; In some embodiments, the colloid is a composite material, comprising at least a substrate layer and an absorbent layer, wherein the substrate layer and the absorbent layer are stacked.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figures 1 to 9 As shown, some embodiments of this application provide a dimming device, mainly used to seal a dimming diaphragm 100 with irregular edges, to ensure the sealing effect and sealing quality of the dimming diaphragm 100.

[0025] The dimming device includes a dimming diaphragm 100 and multiple colloids.

[0026] The dimming film 100 has a first base layer 120, a first conductive layer 130, a dimming layer 140, a second conductive layer 150 and a second base layer 160 stacked in sequence.

[0027] Both the first substrate layer 120 and the second substrate layer 160 are transparent substrates. The "transparent substrate" is an optically grade 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 120 and the second substrate layer 160 can also be glass substrates.

[0028] In addition, both the first conductive layer 130 and the second conductive layer 150 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.

[0029] The first substrate layer 120 has a first surface 121, and the second substrate layer 160 has a second surface 161. The first surface 121 and the second surface 161 are disposed opposite to each other along the stacking direction of the dimming film 100. The edge regions 110 of the first surface 121 and the second surface 161 are connected by a side surface 170. It can be understood that the first surface 121, the second surface 161, and the side surface 170 are connected and enclosed to form the outer surface of the dimming film 100.

[0030] The edges of the dimming diaphragm 100 often have irregular shapes, such as the edge area 110 of the dimming diaphragm 100 having straight edge regions and curved edge regions. Therefore, in order to achieve a complete seal of the edge area 110 of the dimming diaphragm 100, a continuous sealing structure needs to be used in the straight edge regions and curved edge regions. Otherwise, weak points in the seal are likely to appear at the connection between the straight edge regions and curved edge regions, thereby affecting the sealing effect of the dimming diaphragm 100.

[0031] Along the side of the dimming film 100, the dimming film 100 is provided with a plurality of colloids, one end of each colloid is fixed to the edge area of ​​the first surface 121, and the other end extends along the side 170 to the edge area of ​​the second surface 161; wherein the ends of two adjacent colloids partially overlap each other to form an overlap portion 400.

[0032] Specifically, the plurality of colloids include a first colloid 200 and a second colloid 300. This application provides the first colloid 200 and the second colloid 300 in the edge region 110 so that different portions of the edge region 110 of the dimming film 100 can be sealed respectively by the first colloid 200 and the second colloid 300, thereby ensuring the sealing quality of different areas of the edge region 110.

[0033] For example, the first colloid 200 seals the straight edge area of ​​the edge region 110, ensuring the sealing quality of the straight edge area by sealing the straight edge area separately with the first colloid 200. The second colloid 300 seals the curved edge area, ensuring the sealing quality of the curved edge area by sealing the curved edge area separately with the second colloid 300. It can be understood that sealing different areas of the edge region 110 separately with the first colloid 200 and the second colloid 300 not only ensures the sealing quality of different areas of the edge region 110, but also effectively improves the sealing efficiency. Specifically, when the first colloid 200 is used to seal the straight edge area and the second colloid 300 is used to seal the curved edge area, the end of the first colloid 200 covers the end of the second colloid 300.

[0034] In this embodiment, the first colloid 200 and the second colloid 300 are continuously disposed in the edge region 110, and the ends of the first colloid 200 and the second colloid 300 overlap each other to form an overlapping portion 400. The first colloid 200 and the second colloid 300 are connected to form a continuous closed-loop sealing structure in the edge region 110, thereby forming a complete seal on the edge region 110. This not only reduces the difficulty of sealing the dimming film 100, but also ensures the sealing quality of different areas, thereby preventing external moisture from entering the dimming film 100 through the edge region 110, thus improving the service life of the dimming film 100.

[0035] In some embodiments, such as Figure 1 As shown, the dimming film 100 also includes a central portion, and an edge region 110 is adjacent to the central portion to form the dimming film 100.

[0036] The central portion corresponds to the visible area of ​​the dimming film 100, and the edge area 110 corresponds to the non-visible area of ​​the dimming film 100. The area of ​​the central portion is larger than the area of ​​the edge area 110, and the central portion is used to adjust the transmittance of the dimming film 100 or to adjust the amount of light passing through the dimming film 100. In addition, in some embodiments of this application, the central portion is the color-changing area in the dimming film 100, and the edge area 110 is the non-color-changing area of ​​the dimming film 100.

[0037] like Figures 2 to 9As shown, in some embodiments of this application, the edge region 110 of the dimming film 100 is provided with a plurality of notches 111, the plurality of notches 111 are spaced apart, the notches 111 penetrate the first conductive layer 130, the dimming layer 140 and the second conductive layer 150, and the notches 111 also penetrate at least one of the first base layer 120 and the second base layer 160.

[0038] It is understood that in some embodiments, the notch 111 penetrates the first substrate layer 120, the first conductive layer 130, the dimming layer 140, and the second conductive layer 150. In other embodiments, the notch 111 penetrates the second substrate layer 160, the second conductive layer 150, the dimming layer 140, and the first conductive layer 130.

[0039] In this embodiment, the notch 111 penetrates the first substrate layer 120, the first conductive layer 130, the dimming layer 140, the second conductive layer 150, and the second substrate layer 160. The structure of the notch 111 can be specifically set according to the thickness of the edge region 110. By controlling the depth of the notch 111 along the thickness direction of the dimming film 100, the thickness of the edge region 110 can be adjusted, reducing thickness differences and improving the uniformity of the edge region 110 thickness. The width d of the notch satisfies: 4mm ≤ d ≤ 12mm.

[0040] Since the first colloid 200 and the second colloid 300 partially overlap to form an overlapping portion 400, it can be understood that the thickness of the overlapping portion 400 is the sum of the thickness of the first colloid 200 and the thickness of the second colloid 300. In other words, the thickness of the edge region 110 in the overlapping portion 400 is greater than the thickness of other areas of the edge region 110, resulting in a large difference in thickness between the edge region 110 in the overlapping portion 400 and other areas. This makes it easy for the edge of the dimming film to detach or break during the lamination and pressing process.

[0041] Based on this, such as Figures 2 to 9As shown, in some embodiments of this application, projected along the stacking direction of the dimming film 100, the overlapping portion 400 is located in the notch 111, that is, the overlapping portion 400 can be accommodated in the notch 111. By avoiding placing the overlapping portion 400 in other areas of the edge region 110 and increasing the thickness of other areas of the edge region 110, it is possible to avoid the edge region 110 being locally too thick and increasing the thickness difference between various areas of the edge region 110, thereby ensuring the uniformity of the thickness of each area of ​​the edge region 110. It is understood that the thickness of the dimming film 100 at the notch 111 is less than the thickness of other areas of the dimming film 100. By placing the overlapping portion 400 at the notch 111, the corresponding thickness of the dimming film 100 at the notch 111 is increased, thereby reducing the difference between the corresponding thickness of the dimming film 100 at the notch 111 and the corresponding thickness of other areas, ensuring the uniformity of the thickness of the edge region 110 of the dimming film 100, thereby avoiding delamination or breakage during the lamination and pressing process.

[0042] It should be noted that if the width of the notch 111 is small, a portion of the overlapping portion 400 may be disposed within the notch 111, while another portion of the overlapping portion 400 may extend to the first surface 121 and the second surface 161. This results in a significant thickness difference between the thickness of the edge region 110 adjacent to the notch 111 and the thickness of other areas of the edge region 110, potentially leading to delamination or breakage during the lamination and pressing process. Therefore, as... Figure 9 As shown, in some embodiments of this application, along the side of the dimming film 100, the plurality of notches 111 include a first notch 1111 and a second notch 1112, the width of the first notch 1111 is greater than the width of the second notch 1112, and along the projection of the dimming film 100 in the stacking direction, the overlapping portion 400 is located in the first notch 1111.

[0043] like Figure 9 As shown, the width of the first notch 1111 is greater than the width of the second notch 1112, and along the projection of the dimming film 100 in the stacking direction, the overlapping portion 400 is located in the first notch 1111. It can be understood that the overlapping portion 400 is disposed in the wider notch 111 so that the overlapping portion 400 can be completely accommodated in the notch 111, thereby avoiding the overlapping portion 400 being too thick and ensuring the uniformity of the thickness of the edge region 110 of the dimming film 100.

[0044] like Figure 10 and Figure 11 As shown, in some embodiments of this application, the width of the notch 111 along the side of the dimming film is d, where the value of d ranges from 4mm ≤ d ≤ 12mm.

[0045] It is understandable that the value of d can be any of the following ranges: 4mm≤d≤5mm, 5mm≤d≤6mm, 6mm≤d≤7mm, 7mm≤d≤8mm, 8mm≤d≤9mm, 9mm≤d≤10mm, 10mm≤d≤11mm, and 11mm≤d≤12mm. The value can be set according to the actual situation.

[0046] It should be noted that when the value of d is too large, it will cause the area of ​​the notch 111 in the edge region 110 to increase, which will cause the area of ​​the electrode region (first electrode 151 and second electrode 131) in the edge region 110 to decrease. As a result, when the dimming film 100 is electrically connected to the external power supply through the first electrode 151 and the second electrode 131 respectively, the time for the current to be conducted through the first conductive layer 130 and the second conductive layer 150 of the edge region 110 to other areas of the dimming film 100 will increase, which will reduce the color-changing speed of the dimming film 100.

[0047] Furthermore, when the value of the notch 111 is too small, that is, along the arrangement direction of the first colloid 200 and the second colloid 300, the distance between the two ends of the notch 111 decreases. During the lamination and pressing process of the dimming film 100, the first conductive layer 130 and the second conductive layer 150 exposed at both ends of the notch 111 are prone to contact, resulting in a short circuit in the dimming film 100. Moreover, when the notch 111 is too small, it will also make it difficult for the overlapping part 400 to be completely contained in the notch 111, which not only increases the thickness of the dimming device at the notch 111, but also increases the risk of lamination.

[0048] Therefore, this application sets the width of the notch 111 between 4mm and 12mm to ensure the stability and bonding quality of the overlapping portion 400 at the notch 111, and the overlapping portion 400 can be accommodated in the notch 111, thereby avoiding the increase in thickness at the notch 111. It also effectively controls the electrode area of ​​the edge region 110 to ensure the color-changing speed of the dimming film 100. Furthermore, it avoids contact between the first conductive layer 130 and the second conductive layer 150 exposed at both ends of the notch 111 during the lamination and pressing process of the dimming film 100, thus preventing a short circuit in the dimming film 100 and ensuring its safety and stability during use.

[0049] like Figure 1 As shown, in some embodiments of this application, the edge region 110 of the dimming film 100 is provided with alternating first grooves 112 and second grooves 113.

[0050] The first groove 112 penetrates the first base layer 120, the first conductive layer 130 and the dimming layer 140, and exposes a portion of the second conductive layer 150, so as to form a first electrode 151 through the exposed portion of the second conductive layer 150, and to be electrically connected to an external power source through the first electrode 151.

[0051] In addition, the second groove 113 penetrates the second base layer 160, the second conductive layer 150 and the dimming layer 140, and exposes a portion of the first conductive layer 130, so as to form a second electrode 131 through the exposed portion of the first conductive layer 130, and to connect to an external power source through the second electrode 131, thereby connecting the first conductive layer 130 and the second conductive layer 150 to the external power source respectively.

[0052] In this embodiment, the notch 111 communicates with the first groove 112 and the second groove 113. By providing the first adhesive 200 and the second adhesive 300 in the edge region 110, different areas of the edge region 110 can be sealed separately by the first adhesive 200 and the second adhesive 300. This not only ensures the sealing quality of different areas of the edge region 110, but also effectively improves the sealing efficiency. By setting the overlapping part in the notch 111 to reduce the thickness difference between the various areas of the edge region 110, the thickness of the edge region 110 remains uniform, ensuring the stability and safety of the assembled piece.

[0053] like Figure 12 and Figure 13 As shown, in some embodiments of this application, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161, and / or, the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161. It is understood that in some embodiments, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161 to form a seal on the edge area 110 of the dimming film 100, increasing the difficulty for moisture in the environment to enter the dimming film 100, reducing the probability of moisture contacting the dimming layer 140 in the dimming film 100, reducing the risk of discoloration and failure of the dimming film 100, thereby improving the service life of the dimming device.

[0054] In some embodiments, the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161 to form a sealing effect on the edge area 110 of the dimming film 100 through the second colloid 300. This increases the difficulty for moisture in the environment to enter the dimming film 100, reduces the probability of moisture contacting the dimming layer 140 in the dimming film 100, reduces the risk of discoloration and failure of the dimming film 100, and thus improves the service life of the dimming device.

[0055] In some embodiments, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161, and the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161. It is understood that by disposing the first colloid 200 at the first groove 112 and the second colloid 300 at the second groove 113, the first colloid 200 can seal the first groove 112, ensuring the sealing quality of the edge area 110 at the first groove 112, and the second colloid 300 can seal the second groove 113, ensuring the sealing quality of the edge area 110 at the second groove 113.

[0056] like Figures 2 to 9 As shown, in some embodiments of this application, the plurality of colloids includes a first colloid 200 and a second colloid 300.

[0057] The first colloid 200 includes a first adhesive layer 210 and a second adhesive layer 220. One end of the first adhesive layer 210 is disposed on the first surface 121, and one end of the second adhesive layer 220 is disposed on the second surface 161. The first adhesive layer 210 and the second adhesive layer 220 cooperate to cover the side surface 170 of the dimming film 100 and then become a single unit and extend in a direction away from the side surface 170.

[0058] The second colloid 300 includes a third adhesive layer 310 and a fourth adhesive layer 320. One end of the third adhesive layer 310 is disposed on the first surface 121, and one end of the fourth adhesive layer 320 is disposed on the second surface 161. The third adhesive layer 310 and the fourth adhesive layer 320 cooperate to cover the side surface 170 of the dimming film 100 and are then integrated and extend in a direction away from the side surface 170.

[0059] Since the first colloid 200 and the second colloid 300 partially overlap at the notch 111 to form an overlapping portion, the first adhesive layer 210 can partially overlap with the second colloid 300 at the notch 111 to form an overlapping portion, and the second adhesive layer 220 can partially overlap with the second colloid 300 at the notch 111 to form an overlapping portion; in addition, the first colloid 200 and the third adhesive layer 310 can partially overlap at the notch 111 to form an overlapping portion, and the first colloid 200 and the fourth adhesive layer 320 can partially overlap at the notch 111 to form an overlapping portion.

[0060] Specifically, such as Figure 2 As shown, in this embodiment, the first adhesive layer 210 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0061] like Figure 3 As shown, in this embodiment, the second adhesive layer 220 and the third adhesive layer 310 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0062] like Figure 4 As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0063] like Figure 5 As shown, in this embodiment, the second adhesive layer 220, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0064] like Figure 6 As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220 and the third adhesive layer 310 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0065] like Figure 7 As shown, in this embodiment, the first adhesive layer 210, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0066] like Figure 8 As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0067] like Figure 12As shown, in this embodiment, the first adhesive layer 210 and the second adhesive layer 220 extend to cover the side surface 170, and the distance from the side of the connection between the first adhesive layer 210 and the second adhesive layer 220 away from the side surface 170 is equal to the thickness of the first adhesive layer 210 or the thickness of the second adhesive layer 220, that is, the first adhesive layer 210 and the second adhesive layer 220 are integrally connected and formed on the side surface 170. In addition, the third adhesive layer 310 and the fourth adhesive layer 320 extend to cover the side surface 170, and the third adhesive layer 310 and the fourth adhesive layer 320 are integrally formed on the peripheral side surface to form a "U"-shaped sealing structure in the edge area 110. This not only seals the edge area 110, but also reduces the width occupied by the "U"-shaped sealing structure in the edge area 110, thereby adapting to edge areas with small sealing widths and ensuring sealing quality. It can be understood that in this embodiment, both the first adhesive 200 and the second adhesive 300 are set as "U"-shaped sealing structures in the edge area.

[0068] like Figure 13 As shown, in some embodiments of this application, the first colloid 200 includes a first adhesive layer 210 and a second adhesive layer 220. One end of the first adhesive layer 210 is disposed on the first surface 121, and one end of the second adhesive layer is disposed on the second surface 161. The first adhesive layer 210 and the second adhesive layer 220 respectively extend to cover the side surface 170, and the distance from the side of the connection between the first adhesive layer 210 and the second adhesive layer 220 away from the side surface 170 to the side surface 170 is greater than the thickness of the first adhesive layer 210 or the thickness of the second adhesive layer 220, that is, the first adhesive layer 210 and the second adhesive layer 220 overlap on the peripheral side surface. Similarly, the third adhesive layer 310 and the fourth adhesive layer 320 extend to cover the side surface 170 and overlap at the side surface 170 to form a "Y"-shaped sealing structure at the edge area 110. This not only improves the sealing quality of the edge area 110 but also prevents liquid or moisture from entering the dimming diaphragm 100 from the connection between the side surface 170 and the first surface 121, or from the connection between the side surface 170 and the second surface 161. This reduces the probability of moisture contacting the dimming material in the dimming diaphragm 100, reduces the risk of discoloration and failure of the dimming material, and thus improves the service life of the dimming diaphragm 100. It is understood that in this embodiment, both the first adhesive 200 and the second adhesive 300 are configured with a "Y"-shaped sealing structure at the edge area.

[0069] In the above embodiments, the first colloid 200 and the second colloid 300 can be used to set different sealing methods in different areas of the edge region 110. It is understood that the "Y"-shaped sealing structure extends at the side 170, which is beneficial for wrinkle dispersion and can be applied to both straight and curved edge areas; the "U"-shaped sealing structure bends at the side 170, and wrinkles easily form at the bend, making it suitable for straight edge areas. By setting different types of sealing structures, the sealing quality and sealing effect of the edge region 110 in each area can be guaranteed, and the flatness of the edge region seal can also be improved.

[0070] In some embodiments, the first colloid 200 is disposed in the curved edge region of the dimming film 100, and the second colloid 300 is disposed in the straight edge region of the dimming film 100; the first adhesive layer 210 partially covers the third adhesive layer 310, and the second adhesive layer 220 partially covers the fourth adhesive layer 320.

[0071] In this embodiment, the first adhesive 200 in the curved edge region and the second adhesive 300 in the straight edge region can be set in stages. For example, the second adhesive 300 in the straight edge region can be made from a roll of material and set along the length of the straight edge region, while the first adhesive 200 in the curved edge region can be made from a sheet of material with the same shape as the curved edge region for bonding. It is understood that when the second adhesive 300 is set first and then the first adhesive 200 is set, the first adhesive 200 in the curved edge region will cover the end of the second adhesive 300 in the straight edge region, thus forming a continuous first adhesive 200 and second adhesive 300. Furthermore, the curved edge region of the dimming film 100 is usually shorter, while the straight edge region is usually longer. When the first colloid 200 in the curved edge region is set later, it is easier to use the end of the second colloid 300 for positioning. Especially when the curved edge region is located between two straight edge regions, the two ends of the first colloid 200 in the curved edge region can be positioned by the ends of the two second colloids 300 respectively, thereby avoiding the need to position the first colloid 200 at every point in the curved edge region. This reduces the difficulty of setting the first colloid 200 in the curved edge region and simplifies the manufacturing process of the dimming film 100.

[0072] The dimming device also includes a first busbar 500 and a second busbar 600. The first busbar 500 is at least partially located within the first groove 112, and a first adhesive layer 210 and a third adhesive layer 310 cover the first busbar 500. The second busbar 600 is at least partially located within the second groove 113, and a second adhesive layer 220 and a fourth adhesive layer 320 cover the second busbar.

[0073] In the embodiments of this application, such as Figure 12 and Figure 13As shown, the first busbar 500 is at least partially located within the first groove 112, and the second busbar 600 is at least partially located within the second groove 113. By setting the first busbar 500 and the second busbar 600, the first busbar 500 is connected to the first electrode 151 in the first groove 112, and the second busbar 600 is connected to the second electrode 131 in the second groove 113, so that the dimming film 100 can be energized by the first busbar 500 and the second busbar 600, thereby adjusting the transmittance of the dimming film 100.

[0074] The first adhesive layer 210 and the third adhesive layer 310 are located on one side of the first surface 121, covering the first busbar 500. This serves two purposes: firstly, it bonds and fixes the first busbar 500; secondly, it forms a sealed protection against moisture, preventing it from being corroded by moisture and affecting its electrical conductivity. Similarly, the second adhesive layer 220 and the fourth adhesive layer 320 are located on one side of the second surface 161, covering the second busbar 600. This also serves two purposes: firstly, it bonds and fixes the second busbar 600; secondly, it forms a sealed protection against moisture, preventing it from being corroded by moisture and affecting its electrical conductivity.

[0075] In some embodiments, an insulating layer (not shown) is provided in the notch 111, and the insulating layer is disposed between the first busbar 500 and the second busbar 600. In this embodiment, the insulating layer is used to isolate the first busbar 500 and the second busbar 600, preventing the first busbar 500 and the second busbar 600 from forming a conductive path, which would cause the dimming diaphragm 100 to short-circuit, thereby improving product reliability.

[0076] In some embodiments, the colloid is a composite material, comprising at least a substrate layer and an absorbent layer, wherein the substrate layer and the absorbent layer are stacked.

[0077] In the above embodiments of this application, the colloid (including the first colloid 200 and the second colloid 300) comprises at least a substrate layer and a water-absorbing layer. The water-absorbing layer is a polymeric water-absorbing material, which may be one or more of polyurethane (PU), epoxy resin, thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), polyacrylic acid (PAA), polyethylene imine (PEIE), and polyethylene-vinyl acetate copolymer (EVA). By providing water-absorbing material within the colloid layer, the water-vapor barrier effect of the colloid is further enhanced.

[0078] like Figure 14 As shown, some embodiments of this application provide a dimming device, including a first substrate layer 700, a first adhesive layer 800 and a dimming device as described in any of the above embodiments, a second adhesive layer 900 and a second substrate layer 1000, which are stacked sequentially.

[0079] The dimming device also includes a sealing element 1100, which is disposed between the first substrate layer 700 and the second substrate layer 1000 and surrounds the outer periphery of the dimming device. Specifically, the side of the sealing element 1100 facing the first substrate layer 700 is connected to the first substrate layer 700, and the side of the sealing element 1100 facing the second substrate layer 1000 is connected to the second substrate layer 1000. The first adhesive layer 800 and the second adhesive layer 900 are respectively connected to the sealing element 1100 on the side facing the sealing element 1100, so that a sealed space is formed by the first substrate layer 700, the sealing element 1100 and the second substrate layer 1000, and the dimming device is housed in the sealed space.

[0080] Specifically, both the first substrate layer 700 and the second substrate layer 1000 are transparent structures. For example, the first substrate layer 700 and the second substrate layer 1000 can be transparent glass, transparent acrylic sheets, or transparent PVC sheets. Preferably, the first substrate layer 700 and the second substrate layer 1000 are glass, and by sandwiching the dimming device between the first substrate layer 700 and the second substrate layer 1000, a sealed dimming device is formed, preventing the dimming diaphragm 100 from contacting external moisture and oxygen, thereby improving the service life of the dimming diaphragm 100 and the service life of the dimming device.

[0081] The material of the seal 1100 includes one of the adhesives conventional in the art that have the effect of blocking water and oxygen, such as pressure-sensitive adhesives, hot melt adhesives, UV-curable adhesives, thermosetting adhesives, or UV-heat-cured adhesives. It is understood that in some cases, the seal 1100 may be made of the same material as the first adhesive layer 800 and the second adhesive layer 900.

[0082] Additionally, a shielding layer is provided on the surface of the first substrate layer 700 and / or the second substrate layer 1000 corresponding to the edge area 110 of the dimming device. The shielding layer can be located on the inner or outer surface of the first substrate layer 700 and / or the second substrate layer 1000; the shielding layer can be made of shielding materials such as metal or black ink. To prevent users from directly seeing the edge area 110 of the dimming device through the transparent first substrate layer 700 and / or the second substrate layer 1000, and to improve the overall appearance of the device, a shielding layer is provided at the edge of the first substrate layer 700 and / or the second substrate layer 1000. This shielding layer also blocks the busbar and colloid of the dimming device, thereby enhancing the aesthetics of the dimming device.
