[0001] The present application relates to the technical field of dimming, in particular to a dimming device and a dimming apparatus. BACKGROUND

[0002] With the development of technology, people's demand for light and heat regulation is increasing, and dimming technology has also attracted more attention. Specifically, dimming technology refers to the technology that the optical properties of dimming materials change under the action of an external electric field, external light intensity and other external factors. Under normal circumstances, the dimming device containing the dimming material will exhibit reversible changes in color and transparency in appearance. In recent years, dimming devices have been widely used in energy-saving windows, automobile rearview mirrors, display devices, mobile terminals and other fields, and have good market application prospects.

[0003] However, for some dimming devices, the dimming material contained therein is very sensitive to water vapor in the environment. After the dimming material contacts with the water vapor, the dimming device is prone to discoloration and failure, thereby accelerating the damage of the dimming device and reducing its service life.

[0012] In some embodiments, the light control film comprises a first substrate layer, a first conductive layer, an electrochromic layer, a second conductive layer and a second substrate layer which are sequentially stacked;

[0013] The edge region of the light control film has first grooves and second grooves which are alternately arranged;

[0014] The first grooves penetrate the first substrate layer, the first conductive layer and the electrochromic layer, and expose part of the second conductive layer to form a first electrode;

[0015] The second grooves penetrate the second substrate layer, the second conductive layer and the electrochromic layer, and expose part of the first conductive layer to form a second electrode.

[0016] In some embodiments, along the arrangement direction of the first grooves and the second grooves, the first grooves have a first step between two adjacent first grooves, and the second grooves have a second step between two adjacent second grooves;

[0017] The length of the first partition portion is less than the length of the first step, and / or the length of the second partition portion is less than the length of the second step.

[0018] In some embodiments, the first step and the second step at least partially overlap to form an overlapping portion; and the overlapping portion between the first partition portion and the second partition portion is located in the overlapping portion.

[0019] In some embodiments, the light control film further comprises a first bus bar and a second bus bar, the first bus bar is at least partially connected with the first electrode, and the second bus bar is at least partially connected with the second electrode;

[0020] The first sealant on the first surface and the second sealant cover the first bus bar, and the first sealant and the second sealant on the second surface cover the second bus bar;

[0021] The first bus bar is provided with a third partition portion, and the projection of the first partition portion is located in the projection of the third partition portion in the projection direction of the light control film along the thickness direction of the light control film; and / or the second bus bar is provided with a fourth partition portion, and the projection of the second partition portion is located in the projection of the fourth partition portion in the projection direction of the light control film along the thickness direction of the light control film.

[0022] In some embodiments, the edge region of the light control film is provided with a plurality of third grooves arranged at intervals, the third grooves being in communication with adjacent first grooves and second grooves.

[0023] The third grooves pass through the first conductive layer, the electrochromic layer and the second conductive layer, and further pass through at least one of the first substrate layer and the second substrate layer.

In addition, the adjacent first sealant and second sealant are spaced apart on the light control film, which avoids the overlapping of the first sealant and the second sealant to cause the local thickness of the edge region to be too large, reduces the thickness difference of the edge region of the light control film, and thereby reduces the risk of the light control film being detached or damaged during the process of laminating and pressing.

DETAILED DESCRIPTION

[0042] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted throughout by the same or similar reference numerals. The embodiments described below by reference to the accompanying drawings are exemplary and are for the purpose of explaining the present application only, and are not to be understood as limiting the present application.

[0043] In the description of the present application, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and are not to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0044] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0045] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connected", "connection", "fixed", and the like, should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. The "end surface" refers to the surface of the light adjusting device or light adjusting film along the thickness direction after being placed on the horizontal plane, that is, the surface connecting the upper and lower surfaces of the light adjusting device or light adjusting film. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] Since the side edge of the light adjusting device is usually in direct contact with the external environment, at this time, water vapor is easy to contact the light adjusting material in the light adjusting device through the side edge of the light adjusting device, thereby causing the light adjusting film to appear discoloration failure and other problems, so it is necessary to seal the edge of the light adjusting film. However, there is a thickness difference in the edge of the light adjusting film, and in the process of sealing the edge of the light adjusting film in the prior art, the sealing glue is bonded with the entire edge of the light adjusting film, which increases the thickness difference of different regions of the edge of the film, causing the light adjusting film to be delaminated or damaged during the film pressing process.

[0047] As shown in Figures 1 to 9 Some embodiments of the present application provide a light adjusting device, which comprises a light adjusting film 100, a first sealing glue 200 and a second sealing glue 300.

[0048] As shown in Figure 1 The light adjusting film 100 has an edge area 110, which is a non-visible area in the light adjusting film 100. It should be noted that the light adjusting film 100 also includes a central part, and the edge area 110 is adjacent to the central part and surrounds the central part to form the light adjusting film 100. The central part corresponds to the visible area of the light adjusting film 100. The area of the central part is larger than the area of the edge area 110, and the central part adjusts the transmittance of the light adjusting film 100 or adjusts the amount of light passing through the light adjusting film 100. In addition, in some embodiments of the present application, the central part is a discoloration area in the light adjusting film 100, and the edge area 110 is a non-discoloration area of the light adjusting film 100.

[0049] Along the thickness direction of the light adjusting film 100, the light adjusting film 100 has a first surface 111, a second surface 112 and an end surface connecting the first surface 111 and the second surface 112, which are oppositely arranged. The "end surface" in the present application refers to the outer surface of the device along the thickness direction after the device is placed on the horizontal plane.

[0050] The first sealant 200 is arranged on the first surface 111 and the second surface 112, and the second sealant 300 is arranged on the first surface 111 and the second surface 112.

[0051] As shown in Figure 4 and Figure 5 In some embodiments of the present application, the light control film 100 comprises an end surface 119 connecting the first surface 111 and the second surface 112, i.e. the side of the end surface 119 adjacent to the first surface 111 is connected with the edge of the first surface 111, and the side of the end surface 119 adjacent to the second surface 112 is connected with the edge of the second surface 112, so as to form the outer surface of the light control film 100.

[0052] It can be understood that in the above embodiments, the first sealant 200 covers part of the end surface 119 and part of the second surface 112, which increases the contact area between the first sealant 200 and the edge area 110, effectively prevents the sealant from peeling off in the area of the end surface 119 close to the second surface 112, improves the stability of the adhesion between the first sealant 200 and the edge area 110, and avoids liquid or water vapor from entering the light control film 100 through the end surface 119.

[0053] In some other embodiments, the second sealant 300 covers the end surface 119, and the second sealant 300 covers part of the first surface 111, which increases the contact area between the second sealant 300 and the edge area 110, effectively prevents the sealant from peeling off in the area of the end surface 119 close to the first surface 111, improves the stability of the adhesion between the second sealant 300 and the edge area 110, and avoids liquid or water vapor from entering the light control film 100 through the end surface 119.

[0054] In some other embodiments, the two ends of the first sealant 200 and the second sealant 300 pass through the end surface 119 and are fixed on the first surface 111 and the second surface 112, respectively.

[0055] Further, as shown in Figure 2 and Figure 3As shown, the first sealant 200 and the second sealant 300 are respectively disposed along the edge region 110 of the dimming film 100. Adjacent first sealants 200 and second sealants 300 are spaced apart from each other, that is, the first sealants 200 and second sealants 300 are disposed alternately on the first surface 111 and alternately on the second surface 112. Therefore, the first sealants 200 and second sealants 300 can be prevented from overlapping, thus ensuring the uniformity of the thickness of the edge region 110. It should be noted that there is a thickness difference in the edge region 110 of the dimming film 100. If the sealants in the edge region 110 overlap, the thickness of the overlapping part will be greater than the thickness of other edge regions, resulting in a greater thickness difference in the edge region 110. This makes it easy for the dimming film 100 to detach or break during the lamination process.

[0056] In this embodiment, the interval between adjacent first sealant 200 and second sealant 300 is W, and the range of W is 2mm-12mm. Specifically, the length of W can be any length range among 2mm-3mm, 3mm-4mm, 4mm-5mm, 5mm-6mm, 6mm-7mm, 7mm-8mm, 8mm-9mm, 9mm-10mm, 10-11mm, and 11-12mm.

[0057] Based on this, in this embodiment, by misaligning the first sealant 200 and the second sealant 300, the sealing quality of the first sealant 200 and the second sealant 300 on the edge area 110 of the dimming film 100 is ensured, while preventing the orthographic projections of the first sealant 200 and the second sealant 300 along the thickness direction of the dimming film 100 from overlapping, thereby reducing the thickness difference of the edge area 110 and reducing the risk of the dimming film detaching or breaking during the lamination process.

[0058] It should be noted that, in the embodiments of this application, the first sealant 200 and the second sealant 300 can be any one of rubber-type sealant, resin-type sealant, oil-based sealant, vulcanized sealant, heat-converting sealant, oxidation-curing sealant, solvent-evaporating and solidifying sealant, liquid sealant, and high-elasticity sealant.

[0059] like Figures 2 to 7 As shown in some embodiments of this application, it should be noted that the dimming film 100 includes a first base layer 120, a first conductive layer 130, an electrochromic layer 140, a second conductive layer 150, and a second base layer 160 stacked sequentially.

[0060] The first substrate layer 120 and the second substrate layer 160 are both transparent substrates, which are optical-grade transparent materials, and can be flexible substrate materials such as polyethylene glycol terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymer, or cellulose triacetate. The first substrate layer 120 and the second substrate layer 160 can also be glass substrates.

[0061] In addition, the first conductive layer 130 and the second conductive layer 150 are both transparent conductive layers, which can be transparent conductive materials known to those skilled in the art, such as indium-tin oxide (ITO), aluminum zinc oxide (AZO), fluorine-doped tin oxide (FTO), silver nanowire, graphene, carbon nanotube, metal mesh, or silver nanoparticles.

[0062] The electrochromic layer 140 is a sheet layer composed of one or more layers of gel or solid material, such as a polymer dispersed liquid crystal (PDLC) layer, a suspended particle device (SPD), and an electrochromic (EC) type. For the electrochromic (EC) type electrochromic layer 140, it can include a color-changing material layer, an electrolyte layer, and an ion storage layer stacked in order. The materials of the color-changing material layer, the electrolyte layer, and the ion storage layer can be materials in the prior art, which are not specially limited in the present application.

[0063] In some embodiments of the present application, the edge area 110 of the light modulating film 100 has first grooves 113 and second grooves 114 arranged alternately, and the number of the first grooves 113 and the second grooves 114 can be one, two, or any number of two or more, which can be set according to actual conditions.

[0064] In addition, the first grooves 113 penetrate the first substrate layer 120, the first conductive layer 130, and the electrochromic layer 140, and expose a part of the second conductive layer 150, so as to form a first electrode 151 through the exposed part of the second conductive layer 150, and to electrically connect the first electrode 151 with an external power supply.

[0065] The second groove 114 penetrates the second base layer 160, the second conductive layer 150 and the electrochromic layer 140, and exposes part of the first conductive layer 130 to form a second electrode 131, so as to connect the first conductive layer 130 and the second conductive layer 150 with the external power supply through the second electrode 131.

[0066] In some embodiments of the present application, as shown in Figure 5 The first sealant 200 and the second sealant 300 form a "U"-shaped sealing structure on the end surface 119 respectively to seal the edges of the light modulation film 100.

[0067] In other embodiments, as shown in Figure 4 and Figure 6 The first sealant 200 includes a first sealing layer 210 and a second sealing layer 220, and the second sealant 300 includes a third sealing layer 310 and a fourth sealing layer 320. The first sealing layer 210 covering the first surface and the second sealing layer 220 covering the second surface form a "Y"-shaped sealing structure on the end surface. In addition, the third sealing layer 310 covering the first surface 111 and the fourth sealing layer 320 covering the second surface 112 form a "Y"-shaped sealing structure on the end surface, thereby sealing the edges of the light modulation film 100.

[0068] For example, the first sealant 200 can be a Y-shaped sealant, and the second sealant 300 can be a U-shaped sealant; or, the first sealant 200 can be a U-shaped sealant, and the second sealant 300 can be a U-shaped sealant; or, the first sealant 200 can be a U-shaped sealant, and the second sealant 300 can be a Y-shaped sealant; or, the first sealant 200 can be a Y-shaped sealant, and the second sealant 300 can be a Y-shaped sealant.

[0069] It should be noted that in the above embodiments of the present application, the inner surface of the first groove 113 includes the side surfaces of the first base layer 120, the first conductive layer 130 and the electrochromic layer 140, and the inner surface of the second groove 114 includes the side surfaces of the second base layer 160, the second conductive layer 150 and the electrochromic layer 140.

[0070] In the light-adjusting film 100, the stability of the color-changing material in the electrochromic layer 140 is crucial to the color-changing effect of the entire light-adjusting device. By arranging the first sealant 200, the inner surface of the first groove 113 or the inner surface of the second groove 114 can be covered and sealed. Similarly, by arranging the second sealant 300, the inner surface of the first groove 113 or the inner surface of the second groove 114 can be covered and sealed, so as to avoid water vapor, impurities and other pollutants from entering the inside of the electrochromic layer 140 through the inner surface of the first groove 113 or the inner surface of the second groove 114, thereby achieving the sealing protection of the electrochromic layer 140 in the central part of the light-adjusting film.

[0071] In the present application, the first sealant 200 and the second sealant 300 are arranged to strengthen the sealing at the inner surface of the first groove 113 and the inner surface of the second groove 114, so as to better ensure the sealing effect. At the same time, since the edge area 110 of the light-adjusting film 100 has the first groove 113 and the second groove 114 arranged alternately, the thickness at the first groove 113 and the second groove 114 is relatively thin, while the thickness between the first groove 113 and the second groove 114 is relatively thick. Therefore, considering the thickness difference of the edge area 110, the first sealant 200 and the second sealant 300 are separated from each other and arranged alternately along the first groove 113 and the second groove 114 of the edge area 110, so as to control the thickness of the edge area 110 of the light-adjusting film 100 and avoid the thickness difference between the groove and the non-groove of the edge area 110 of the light-adjusting film 100 being too large, which may cause the light-adjusting film 100 to be delaminated or damaged during the pressing process.

[0072] For example, one end of each first sealant 200 is arranged at the first surface 111 and covers the inner surface of the first groove 113, and the other end extends to the second surface 112 through the end face 119; one end of each second sealant 300 is arranged at the second surface 112 and covers the inner surface of the second groove 114, and the other end extends to the first surface 111 through the end face 119; the first sealant 200 and the second sealant 300 are arranged alternately along the edge area 110 of the light-adjusting film 100.

[0073] For example, one end of each first sealant 200 is arranged at the first surface 111 and covers the inner surface of the first groove 113, and the other end extends to the second surface 112 through the end face 119; one end of each second sealant 300 is arranged at the second surface 112 and covers the inner surface of the second groove 114, and the other end extends to the first surface 111 through the end face 119; the first sealant 200 and the second sealant 300 are arranged alternately along the edge area 110 of the light-adjusting film 100. Figure 2As shown, the first surface 111 forms a first partition 400 between the adjacent first sealant 200 and second sealant 300; and the second surface 112 forms a second partition 500 between the adjacent first sealant 200 and second sealant 300. Specifically, in some embodiments of the present application, the first sealant layer 210 and the third sealant layer 310 are arranged in an interval along the arrangement direction of the first groove 113 and the second groove 114, and a first partition 400 is formed between two adjacent first sealant layer 210 and third sealant layer 310; and / or, the third sealant layer and the fourth sealant layer are arranged in an interval along the arrangement direction of the first groove and the second groove, and a second partition 500 is formed between two adjacent second sealant layer 220 and fourth sealant layer 320.

[0074] It can be understood that, in the present embodiment, the first sealant layer 210 and the third sealant layer 310 are arranged in an interval along the arrangement direction of the first groove 113 and the second groove 114, and a first partition 400 is formed between two adjacent first sealant layer 210 and third sealant layer 310, so as to form a space for the edge area 110 through the first partition 400. By controlling the position of the interval between two adjacent first sealant layer 210 and third sealant layer 310, that is, by adjusting the position of the first partition 400 on the first surface 111, the thickness difference of the edge area 110 can be adjusted.

[0075] It can be understood that, in the present embodiment, the first sealant layer 210 and the third sealant layer 310 are arranged in an interval along the arrangement direction of the first groove 113 and the second groove 114, and a first partition 400 is formed between two adjacent first sealant layer 210 and third sealant layer 310, so as to form a space for the edge area 110 through the first partition 400. By controlling the position of the interval between two adjacent first sealant layer 210 and third sealant layer 310, that is, by adjusting the position of the first partition 400 on the first surface 111, the thickness difference of the edge area 110 can be adjusted.

[0076] It can be understood that, in the present embodiment, the first sealant layer 210 and the third sealant layer 310 are arranged in an interval along the arrangement direction of the first groove 113 and the second groove 114, and a first partition 400 is formed between two adjacent first sealant layer 210 and third sealant layer 310, so as to form a space for the edge area 110 through the first partition 400. By controlling the position of the interval between two adjacent first sealant layer 210 and third sealant layer 310, that is, by adjusting the position of the first partition 400 on the first surface 111, the thickness difference of the edge area 110 can be adjusted.

[0077] It can be understood that, in the present embodiment, the first sealant layer 210 and the third sealant layer 310 are arranged in an interval along the arrangement direction of the first groove 113 and the second groove 114, and a first partition 400 is formed between two adjacent first sealant layer 210 and third sealant layer 310, so as to form a space for the edge area 110 through the first partition 400. By controlling the position of the interval between two adjacent first sealant layer 210 and third sealant layer 310, that is, by adjusting the position of the first partition 400 on the first surface 111, the thickness difference of the edge area 110 can be adjusted.

[0078] In the above embodiments, by arranging the first partitioning portion 400 and the second partitioning portion 500 in the area where the edge area 110 has a larger thickness, the thickness of the area where the edge area 110 has a larger thickness is not increased, and the uniformity of the thickness increase of the area where the edge area 110 has a smaller thickness is ensured, thereby further reducing the thickness difference of the edge area 110, improving the stability and safety of the light control film 100 during the lamination process, and effectively sealing the edge area 110 by the first sealant 200 and the second sealant 300 to ensure the sealing quality of the edge area 110.

[0079] As shown in FIG. 1, in some embodiments of the present application, the orthographic projection of the first partitioning portion 400 and the orthographic projection of the second partitioning portion 500 at least partially coincide along the thickness direction of the light control film 100. Figure 2 In some embodiments, the orthographic projection of the first partitioning portion 400 and the orthographic projection of the second partitioning portion 500 at least partially coincide along the thickness direction of the light control film 100. In other embodiments, as shown in FIG. 2, the orthographic projection of the first partitioning portion 400 and the orthographic projection of the second partitioning portion 500 completely coincide along the thickness direction of the light control film 100.

[0080] Figure 2 It can be understood that the overlapping part between the first partitioning portion 400 and the second partitioning portion 500 can be adjusted according to the thickness difference of the edge area 110. It should be noted that due to the uneven thickness of the edge area 110, by arranging the overlapping part between the first partitioning portion 400 and the second partitioning portion 500 in the area where the edge area 110 has a larger thickness, the first sealant 200 and the second sealant 300 are not arranged in the area where the edge area 110 has a larger thickness, i.e., the first sealant 200 and the second sealant 300 are arranged in the area where the edge area 110 has a relatively smaller thickness, thereby increasing the thickness of the area where the edge area 110 has a smaller thickness, reducing the thickness difference of the edge area 110, and improving the uniformity of the thickness of the edge area 110.

[0081] In some embodiments of the present application, along the arrangement direction of the first grooves 113 and the second grooves 114, the first step 116 is arranged between two adjacent first grooves 113, and the second step 117 is arranged between two adjacent second grooves 114.

[0082] In some embodiments of the present application, along the arrangement direction of the first grooves 113 and the second grooves 114, the first step 116 is arranged between two adjacent first grooves 113, and the second step 117 is arranged between two adjacent second grooves 114.

[0083] ​The length of the first partition part 400 is less than the length of the first step 116, so that the first sealing layer 210 covers a part of the first recess 113 on the first surface 111 and covers another part of the first surface 111, so that the first sealing layer 210 in the first recess 113 can cover the groove wall of the first recess 113, to prevent water vapor from contacting the electrochromic layer 140 from the groove wall of the first recess 113, and to ensure the service life of the color-changing material in the light control film 100.

[0084] In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110. Figure 2 In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110.

[0085] Figure 2 In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110.

[0086] In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110. Figure 2 In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110.

[0087] In some embodiments, as shown in FIG. 1, by making the length of the first partition part 400 less than the length of the first step 116, the length of the first partition part 400 is reduced to increase the contact area between the first sealing layer 210 and the first surface 111 and the contact area between the third sealing layer 310 and the first surface 111, thereby improving the stability of the connection between the first sealing layer 210 and the third sealing layer 310 and the light control film 100, and thereby improving the sealing quality of the first sealant 200 and the second sealant 300 in the edge area 110.

[0088] Figure 7 ​​As shown, in some embodiments of this application, the dimming film 100 further includes a first busbar 600 and a second busbar 700. The first busbar 600 is at least partially connected to the first electrode 151, and the second busbar 700 is at least partially connected to the second electrode 131, so as to accelerate the conductivity of the dimming film 100 and improve the color-changing speed of the dimming film 100 through the first busbar 600 and the second busbar 700. The first sealant 200 and the second sealant 300 on the first surface 111 cover the first busbar 600, and the first sealant 200 and the second sealant 300 on the second surface 112 cover the second busbar 700.

[0089] In some embodiments, the first busbar 600 is provided with a third partition 610, which is projected along the thickness direction of the dimming diaphragm. The orthographic projection of the first partition 600 is located in the orthographic projection of the third partition 610. That is, the end of the first sealing layer 210 or the third sealing layer 310 is provided beyond the end of the first busbar 600. On the one hand, the first busbar 600 is fixed to the first surface 111 by the first sealing layer 210 and the third sealing layer 310, ensuring the stability of the first busbar 600 in the edge region 110. On the other hand, it can prevent the part of the first busbar 600 facing the first partition 400 from being exposed to the outside, thereby preventing the first busbar 600 from being corroded by water vapor in the environment and improving the service life of the first busbar 600.

[0090] In other embodiments, the second busbar 700 is provided with a fourth partition 710, which is projected along the thickness direction of the dimming film. The orthographic projection of the second partition 500 is located in the orthographic projection of the fourth partition 710. That is, the end of the second sealing layer 220 or the fourth sealing layer 320 is provided beyond the end of the second busbar 700. On the one hand, the second busbar 700 is fixed to the second surface 112 by the second sealing layer 220 and the fourth sealing layer 320, ensuring the stability of the second busbar 700 in the edge region 110. On the other hand, it can prevent the part of the second busbar 700 facing the second partition 500 from being exposed to the outside, thereby preventing the second busbar 700 from being corroded by water vapor in the environment and improving the service life of the second busbar 700.

[0091] like Figure 3 and Figure 7 As shown, in some embodiments of this application, the edge region 110 of the dimming film is provided with a plurality of mutually spaced third grooves 115, and the third grooves 115 connect adjacent first grooves 113 and second grooves 114. It can be understood that the third grooves 115 are disposed between adjacent first grooves 113 and second grooves 114.

[0092] The third groove 115 penetrates the first conductive layer 130, the electrochromic layer 140, and the second conductive layer 150, and also penetrates at least one of the first substrate layer 120 and the second substrate layer 160. The structure of the third groove 115 can be specifically set according to the thickness of the edge region 110, so as to adjust the thickness of the edge region 110 by controlling the thickness of the third groove 115 along the thickness direction of the dimming film 100.

[0093] It is understood that in some embodiments, the third groove 115 penetrates the first substrate layer 120, the first conductive layer 130, the electrochromic layer 140, and the second conductive layer 150. In other embodiments, the third groove 115 penetrates the second substrate layer 160, the second conductive layer 150, the electrochromic layer 140, and the first conductive layer 130.

[0094] In the above embodiments of this application, the dimming film 100 is provided with busbars on both sides in the thickness direction. For example, the busbars may be other conductive materials such as conductive copper foil, conductive adhesive and conductive resin. Thus, a multi-electrode structure can be formed at the edge of the dimming film 100 to accelerate the color change speed of the dimming film 100.

[0095] like Figure 8 As shown, in some embodiments of this application, the third groove 115 also penetrates the first base layer 120 and the second base layer 160. An insulating portion 1151 is provided in the third groove 115. The insulating portion 1151 has a first contact surface and a second contact surface disposed opposite to each other. The end of the first busbar 600 near the insulating portion 1151 contacts the first contact surface of the insulating portion 1151, and the end of the second busbar 700 near the insulating portion 1151 contacts the second contact surface of the insulating portion 1151.

[0096] In this embodiment, the third groove 115 penetrates the first substrate layer 120, the first conductive layer 130, the electrochromic layer 140, the second conductive layer 150, and the second substrate layer 160. By providing the third groove 115 in the overlapping portion 118, the thickness difference of the edge region 110 is reduced, and the uniformity of the thickness of the edge region 110 is improved.

[0097] Furthermore, by providing the insulating portion 1151, it is possible to prevent the first busbar 600 exposed to the first partition portion 400 and the second busbar 700 exposed to the second partition portion 500 from coming into contact under pressure, thus avoiding a short circuit in the dimming diaphragm 100. This ensures the stability and safety of the electrical connection between the first busbar 600 and the second busbar 700 and the external power supply, respectively. It should be noted that in some embodiments, the thickness of the insulating portion 1151 is greater than the thickness of the first groove 113 and / or the second groove 114.

[0098] like Figure 9As shown, some embodiments of the present application provide a dimming device, which comprises a first substrate layer 800, a first adhesive layer 900 and the dimming device of any one of the above embodiments stacked in sequence, a second adhesive layer 1000 and a second substrate layer 1100.

[0099] The dimming device further comprises a sealing member 1200, which is arranged between the first substrate layer 800 and the second substrate layer 1100, i.e. one side of the sealing member 1200 facing the first substrate layer 800 is connected to the first substrate layer 800, and the other side of the sealing member 1200 facing the second substrate layer 1100 is connected to the second substrate layer 1100, and one side of the first adhesive layer 900 and the second adhesive layer 1000 facing the sealing member 1200 is connected to the sealing member 1200, so as to form a sealed space enclosed by the first substrate layer 800, the sealing member 1200 and the second substrate layer 1100, i.e. the dimming device is accommodated in the sealed space.

[0100] Specifically, the first substrate layer 800 and the second substrate layer 1100 are both transparent structures, for example, the first substrate layer 800 and the second substrate layer 1100 can be transparent glass, transparent acrylic plate or transparent PVC plate, etc. Preferably, the first substrate layer 800 and the second substrate layer 1100 are glass, and the dimming device is sandwiched between the first substrate layer 800 and the second substrate layer 1100 to form a sealed dimming device, so as to avoid the dimming film 100 from contacting with external moisture and oxygen, thereby improving the service life of the dimming film 100 and the service life of the dimming device.

[0101] The material of the sealing member 1200 includes conventional glue with water and oxygen blocking effect in the art, for example, one of pressure-sensitive glue, hot melt glue, UV light curing glue, heat curing glue or UV and heat double curing glue. It can be understood that in some cases, the sealing member 1200 can adopt the same material as the first adhesive layer 900 and the second adhesive layer 1000.

[0102] In addition, the surface of the first substrate layer 800 and / or the second substrate layer 1100 corresponding to the edge area 110 of the dimming device is provided with a shielding layer, which can be arranged on the inner surface or the outer surface of the first substrate layer 800 and / or the second substrate layer 1100; the shielding layer can be made of metal, black ink or other shielding materials. In order to avoid the user directly seeing the edge area 110 of the dimming device through the transparent first substrate layer 800 and / or the second substrate layer 1100, and make the appearance of the entire device more beautiful. Therefore, the shielding layer is arranged at the edge of the first substrate layer 800 and / or the second substrate layer 1100, and the shielding layer shields the bus bar and the sealing glue of the dimming device, thereby improving the appearance of the dimming device.

[0103] The light adjusting film sheet 100 or the light adjusting device of some embodiments of the present application can be used in a light adjusting product, which has the functions and beneficial effects of the light adjusting device or the light adjusting device in any of the above embodiments, which will not be repeated here.

[0104] The light adjusting product includes any one of a rearview mirror, a curtain wall, an automobile sunroof, an automobile side window, an automobile windshield, a housing of an electronic product, glasses, a vehicle, and a display panel. The vehicle includes an automobile, a train, an airplane, a ship, etc., and the electronic product includes a mobile phone, a computer, a tablet, a smart wearable device, etc.; the glasses include ordinary glasses, AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, sunglasses, or ski goggles, etc.
