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 adjustable light and heat 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 color and transparency in dimming devices containing the material. In recent years, dimming devices have been widely used in energy-saving windows, automotive rearview mirrors, display devices, and mobile terminals, demonstrating promising market prospects.

[0003] However, for some dimming devices, the stability of the dimming material within the device is easily affected by the environment during use. After prolonged use, some dimming material may precipitate out, spreading to the electrodes located at the device's edges. This affects the conductivity at the device's edges, thereby impacting the color-changing performance. Utility Model Content

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] like Figures 1 to 7 As shown, some embodiments of this application provide a dimming device having a thickness direction. The dimming device includes a dimming diaphragm 100, a first sealing member 200, and a second sealing member 300. The first sealing member 200 and the second sealing member 300 are mainly used to block the precipitated substances and extend the path of the dimming material precipitated in the dimming device, so as to improve the stability and safety of the dimming device during use.

[0056] The dimming device can be an electrochromic dimming device, a liquid crystal dimming device, a photochromic dimming device, etc. The dimming device includes a dimming medium and conductive substrates disposed on both sides of the dimming medium. Preferably, the dimming device is an electrochromic dimming device. Optionally, the dimming medium is one or a combination of two or more of liquid dimming media, solid dimming media, or sol-gel dimming media. Preferably, the dimming medium is a solid dimming medium. More preferably, the dimming medium is a solid electrochromic layer, which includes an ion storage layer, an electrolyte layer, and a color-changing material layer stacked sequentially.

[0057] In some embodiments of this application, the dimming film 100 includes a first base layer 150, a first conductive layer 160, an electrochromic layer 170, a second conductive layer 180, and a second base layer 190, which are stacked sequentially.

[0058] The first substrate layer 150 and the second substrate layer 190 are both transparent substrates. The "transparent substrate" is an optical-grade transparent material, which can be a flexible substrate material, such as polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymer, or cellulose triacetate.

[0059] In addition, both the first conductive layer 160 and the second conductive layer 180 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.

[0060] Furthermore, the dimming film 100 includes a first surface 110 and a second surface 120 disposed opposite to each other along its thickness direction, and a peripheral surface located between and connecting the first surface 110 and the second surface 120. The dimming film 100 has an edge region 130, which, as understood, is... Figure 1Taking the dimming film 100 as an example, the edge region 130 refers to the four peripheral edges of the film. Correspondingly, the four peripheral edges and peripheral surfaces of the first surface 110 and the second surface 120 together form the edge region 130. The edge region 130 is provided with a plurality of mutually spaced first grooves 131 and a plurality of mutually spaced second grooves 132. Along the thickness direction, each first groove 131 penetrates the first surface 110, that is, the opening of the first groove 131 along the thickness direction faces the first surface 110, and the edge of the opening of the first groove 131 is flush with the first surface 110. In addition, each second groove 132 penetrates the second surface 120, that is, the opening of the second groove 132 along the thickness direction faces the second surface 120, and the edge of the opening of the second groove 132 is flush with the second surface 120.

[0061] It is understandable that, along the thickness direction, the openings of the first groove 131 and the second groove 132 are set in opposite directions.

[0062] In some embodiments, along the thickness direction, the projections of each first groove 131 and an adjacent second groove 132 on the plane containing the first surface 110 or the second surface 120 are offset from each other.

[0063] The dimming device includes at least one first seal 200 and at least one second seal 300. It is understood that the number of first seals 200 and second seals 300 can be one, two, or more, depending on the specific circumstances. The first seals 200 and 300 are respectively disposed in the edge region 130 along the arrangement direction of the plurality of first grooves 131 and the plurality of second grooves 132, covering all first grooves 131 and all second grooves 132 to seal the edge region 130. Specifically, in this application, "covering" means that the seal is in contact with the bottom and side walls of the corresponding groove, and the seal extends to the first surface 110 or the second surface 120 near the groove.

[0064] The first sealing member 200 and the second sealing member 300 may both be strip-shaped. A portion of the first sealing member 200 and a portion of the second sealing member 300 are disposed on the first surface 110 and cooperate to cover the first groove 131. It should be noted that, in this embodiment, along the thickness direction, the first sealing member 200 disposed on the first surface 110 covers at least a portion of the plurality of first grooves 131; that is, the first sealing member 200 disposed on the first surface 110 completely covers at least one first groove 131. Furthermore, the second sealing member 300 disposed on the first surface 110 covers another portion of the first grooves 131. It should be noted that, as mentioned here, the second sealing member 300 covering another portion of the first grooves 131 means that the second sealing member 300 covers the first grooves 131 that were not previously covered by the second sealing member 300; that is, the second sealing member 300 disposed on the first surface 110 completely covers the first groove 131.

[0065] It is understood that the sum of the number of first grooves 131 covered by the first seal 200 and the number of first grooves 131 covered by the second seal 300 is less than or equal to the total number of first grooves 131 provided in the edge area.

[0066] For example, in some embodiments, the number of first grooves 131 is N, where N is a positive integer and N≥2. If the first seal 200 covers x first grooves 131, then the second seal 300 covers Nx first grooves 131, where x and N satisfy the relationship: x<N, and x is a positive integer.

[0067] Additionally, another portion of the first sealing member 200 and another portion of the second sealing member 300 are disposed on the second surface 120 and cooperate to cover the second groove 132. It should be noted that, in this embodiment, along the thickness direction, the first sealing member 200 disposed on the second surface 120 covers a portion of the second groove 132. Specifically, the first sealing member 200 covering a portion of the second groove 132 means that the first sealing member 200 covers one or more of the plurality of second grooves 132; that is, the first sealing member 200 disposed on the second surface 120 covers at least one second groove 132. Furthermore, the second sealing member 300 disposed on the second surface 120 covers another portion of the second groove 132. Specifically, the second sealing member 300 covering another portion of the second groove 132 means that the second sealing member 300 covers the second groove 132 on the second surface 120 side that is not covered by the first sealing member 200; that is, the second sealing member 300 disposed on the second surface 120 completely covers the second groove 132.

[0068] It is understood that the sum of the number of second grooves 132 covered by the first seal 200 and the number of second grooves 132 covered by the second seal 300 is less than or equal to the total number of second grooves 132 provided in the edge area.

[0069] For example, in some embodiments, the number of second grooves 132 is M, where M is a positive integer and M≥2. If the first seal 200 covers y second grooves 132, then the second seal 300 covers My second grooves 132, where y and M satisfy the relationship: y<M, and y is a positive integer.

[0070] In this embodiment, the ends of the first seal 200 and the second seal 300 on the first surface 110 are both located outside the first groove 131. That is, at least a portion of the first seal 200 and the second seal 300 are disposed on the first surface 110. In other words, since the first seal 200 and the second seal 300 disposed on the first surface 110 completely cover the first groove 131, the substances precipitated in the electrochromic layer 170 at the edge of the dimming film 100 can be blocked by the first seal 200 and the second seal 300 when they diffuse outward.

[0071] In addition, the ends of the first seal 200 and the second seal 300 on the second surface 120 are both located outside the second groove 132. That is, another part of the first seal 200 and the second seal 300 is disposed on the second surface 120. In other words, since the first seal 200 and the second seal 300 disposed on the second surface 120 completely cover the second groove 132, the substances precipitated in the electrochromic layer 170 at the edge of the dimming film 100 can be blocked by the first seal 200 and the second seal 300 when they diffuse outward.

[0072] It should be noted that by placing the ends of the first seal 200 and the second seal 300 near the first surface 110 on the first surface 110, and by placing the ends of the first seal 200 and the second seal 300 near the second surface 120 on the second surface 120, not only can the electrochromic layer 170 exposed in the first groove 131 and the second groove 132 be covered and protected, but the precipitated material can also be blocked, thereby preventing the precipitated material from directly contacting the conductive material (such as the metal busbar) in the edge area, thus ensuring that the conductivity of the dimming device is not affected. Furthermore, since the precipitated material has a certain degree of fluidity, it can flow along the length of the seal on the surface of the seal, thus requiring a relatively long flow path to reach the end of the seal. During this process, due to the presence of the first seal 200 and the second seal 300, the precipitated material not only needs to overcome the internal viscosity of the material, but also experiences material dispersion due to the extended path, thus significantly reducing the possibility of the precipitated material overflowing to the end of the seal. Meanwhile, since the first surface 110 and the first groove 131, and the second surface 120 and the second groove 132 are not on the same plane, the precipitated material needs to cross a height difference when diffusing from the groove area to the surface area, thus forming additional resistance during the diffusion process, which further increases the difficulty of the diffusion of the precipitated material.

[0073] In the embodiments of this application, the covering effect of the first sealing member 200 and the second sealing member 300, the extension of the flow path of the precipitated substance, and the height difference between the multiple planes together form multiple physical barriers to block the precipitated substance, effectively suppressing the overflow of the precipitated substance and ensuring that the conductive materials (such as busbars and electrodes) in the dimming device are not corroded by the precipitated substance, thus greatly improving the stability and service life of the dimming device. The electrochromic layer 170 may include a color-changing material layer, an electrolyte layer, and an ion storage layer. The precipitated substance may originate from any one of the above layers, or from two or more layers.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first surface 110 has a first partition area 111, which is located between two adjacent first grooves 131, that is, the first partition area 111 separates the two adjacent first grooves 131.

[0075] It should be noted that in some embodiments, there are multiple first partition areas 111, which are spaced apart to form the first surface 110. It is understood that the first groove 131 and the first partition areas 111 are alternately arranged on one side of the first surface 110 of the edge area 130.

[0076] The second surface 120 has a second partition region 121 located between two adjacent second grooves 132, i.e., the second partition region 121 separates two adjacent second grooves 132. In some embodiments, there are multiple second partition regions 121, which are spaced apart to form the second surface 120. It is understood that the second grooves 132 and the second partition regions 121 are alternately arranged on one side of the second surface 120 of the edge region 130.

[0077] In addition, a portion of the first seal 200 and the second seal 300 may be disposed in the first partition area 111. In this embodiment, the ends of the first seal 200 and the second seal 300 on the first surface 110 are disposed in the first partition area 111 so that the first seal 200 and the second seal 300 on the first surface 110 form a barrier to the precipitated material, thereby preventing the precipitated material in the dimming film 100 from overflowing from the first partition area 111.

[0078] In this embodiment, the other parts of the first seal 200 and the second seal 300 can be disposed in the second partition area 121. The ends of the first seal 200 and the second seal 300 on the second surface 120 are disposed in the second partition area 121 so that the first seal 200 and the second seal 300 on the second surface 120 can block the precipitated material to prevent the precipitated material in the dimming film 100 from overflowing from the second partition area 121.

[0079] like Figures 2 to 5 As shown, in some embodiments of this application, the first sealant 200 includes a first sealant 210 and a second sealant 220.

[0080] The first sealant 210 is disposed on one side of the first surface 110 in the edge region 130. It should be noted that the first sealant 200 disposed on the first surface 110 covers at least part of the first groove 131. Specifically, the first sealant 210 in the first sealant 200 covers at least a portion of the plurality of first grooves 131. By placing the end of the first sealant 210 in the first partition region 111, the first sealant 210 simultaneously has the functions of covering the side of the electrochromic layer 170 in the first groove 131 and extending the flow path of the precipitated material. At the same time, by utilizing the height difference between the first groove 131 and the first surface 110, a physical barrier system is formed to prevent the spread of the precipitated material, effectively preventing the precipitated material from diffusing into the area where the busbar is located, thereby ensuring that the internal busbar of the dimming device is not affected by the erosion of the precipitated material, thereby improving the stability and service life of the dimming device.

[0081] In addition, the second sealant 220 is disposed on one side of the edge area 130 located on the second surface 120. It should be noted that the first sealant 200 disposed on the second surface 120 covers at least part of the second groove 132. Specifically, the second sealant 220 in the first sealant 200 covers a portion of the second groove 132. By placing the end of the second sealant 220 in the second partition area 121, the second sealant 220 simultaneously has the functions of covering the side of the electrochromic layer 170 in the second groove 132 and extending the flow path of the precipitated material. At the same time, by utilizing the height difference between the second groove 132 and the second surface 120, a physical barrier system is formed to prevent the spread of the precipitated material, effectively preventing the precipitated material from diffusing into the area where the busbar is located, thereby protecting the internal busbar of the dimming device from the erosion of the precipitated material, thereby improving the stability and service life of the dimming device.

[0082] like Figures 2 to 5 As shown, in some embodiments of this application, the second seal 300 includes a third sealant 310 and a fourth sealant 320.

[0083] The third sealant 310 is disposed on one side of the edge region 130 located on the first surface 110. It should be noted that the second sealant 300 disposed on the first surface 110 covers at least a portion of the first groove 131. Specifically, the third sealant 310 of the second sealant 300 covers at least a portion of the multiple first grooves 131. By placing the end of the third sealant 310 in the first partition region 111, the third sealant 310 simultaneously has the functions of covering the side of the electrochromic layer 170 in the first groove 131 and extending the flow path of the precipitated material. At the same time, by utilizing the height difference between the first groove 131 and the first surface 110, a physical barrier system is formed to prevent the spread of the precipitated material, effectively preventing the precipitated material from diffusing into the area where the busbar is located, thereby protecting the internal busbar of the dimming device from the erosion of the precipitated material, thereby improving the stability and service life of the dimming device.

[0084] Furthermore, the fourth sealant 320 is disposed on one side of the edge region 130 located on the second surface 120. It should be noted that since the second sealant 300 disposed on the second surface 120 covers at least part of the second groove 132, specifically, the fourth sealant 320 in the second sealant 300 covers at least a portion of the multiple second grooves 132, by placing the end of the fourth sealant 320 in the second partition region 121, the fourth sealant 320 simultaneously has the functions of covering the side of the electrochromic layer 170 in the second groove 132 and extending the flow path of the precipitated material. At the same time, by utilizing the height difference between the second groove 132 and the second surface 120, a physical barrier system is formed to prevent the spread of the precipitated material, effectively preventing the precipitated material from diffusing into the area where the busbar is located, thereby protecting the internal busbar of the dimming device from the erosion of the precipitated material, thereby improving the stability and service life of the dimming device.

[0085] like Figure 1 As shown, in some embodiments, the dimming diaphragm 100 further includes a central portion, with an edge region 130 adjacent to the central portion to form the dimming diaphragm 100.

[0086] The central portion corresponds to the visible area of ​​the dimming film 100, while the edge area 130 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 130, and the central portion serves to adjust the transmittance of the dimming film 100 or the amount of light passing through it. Additionally, in some embodiments of this application, the central portion is the color-changing area of ​​the dimming film 100, and the edge area 130 is the non-color-changing area of ​​the dimming film 100.

[0087] like Figure 2 As shown, in some embodiments of this application, the first seal 200 and the second seal 300 are spaced apart along the arrangement direction of the first and second grooves. A first gap 400 is formed between the first sealant 210 and the third sealant 310, and the projection of the first gap 400 along the thickness direction is located in the first partition region 111. It should be noted that during the lamination process, air bubbles may form between the layers inside the dimmer under compressive stress, causing protrusions. By spaced apart the first sealant 210 and the third sealant 310, residual gas at the protrusions can be discharged from the first gap 400 during lamination, thereby ensuring the flatness and thickness uniformity of the dimmer device.

[0088] In addition, the ends of the first sealant 210 near the third sealant 310 and the ends of the third sealant 310 near the first sealant 210 are spaced apart on the same first partition area 111, so as to form a seal for the first groove 131 by the first sealant 210 and the third sealant 310, and at the same time, to block the substances precipitated from the side of the electrochromic layer 170.

[0089] A second gap 500 is formed between the second sealant 220 and the fourth sealant 320, and the projection of the second gap 500 along the thickness direction is located in the second partition region 121. It should be noted that during the lamination process, air bubbles may form between the layers inside the dimming device under compressive stress, causing protrusions. By spaced the second sealant 220 and the fourth sealant 320, residual gas at the protrusions can be discharged through the second gap during lamination, thereby ensuring the flatness and thickness uniformity of the dimming device.

[0090] In addition, the ends of the second sealant 220 near the fourth sealant 320 and the ends of the fourth sealant 320 near the second sealant 220 are spaced apart on the same second partition area 121, so as to form a seal for the second groove 132 by the second sealant 220 and the fourth sealant 320, and at the same time, to block the substances precipitated from the side of the electrochromic layer 170.

[0091] In the above embodiment, along the thickness direction, the projections of the first gap portion 400 and the second gap portion 500 on the first surface 110 are spaced apart from each other.

[0092] like Figure 3 As shown, in some embodiments of this application, one end of the first sealant 210 and one end of the third sealant 310 overlap to form a first overlap portion 600, and the projection of the first overlap portion 600 along the thickness direction is located in the first partition region 111. It is understood that the ends of the first sealant 210 near the third sealant 310 and the ends of the third sealant 310 near the first sealant 210 are disposed on the same first partition region 111 and connected to each other to form the first overlap portion 600, thereby forming a sealing structure on the first surface 110 to further improve the sealing quality of the first groove 131, thereby blocking substances precipitated from the side of the electrochromic layer 170.

[0093] Wherein, one end of the second sealant 220 and one end of the fourth sealant 320 overlap to form a second overlap portion 700, and the projection of the second overlap portion 700 along the thickness direction is located in the second partition area 121.

[0094] It is understood that the ends of the second sealant 220 near the fourth sealant 320 and the ends of the fourth sealant 320 near the second sealant 220 are disposed on the same second partition area 121 and are connected to each other to form a second overlap 700, thereby forming a sealing structure on the second surface 120 to further improve the sealing quality of the second groove, thereby blocking the substances precipitated from the side of the electrochromic layer 170.

[0095] In the above embodiment, along the thickness direction, the projections of the first overlapping portion 600 and the second overlapping portion 700 on the first surface 110 are spaced apart from each other.

[0096] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the edge region 130 includes a peripheral side surface 140 connecting the first surface 110 and the second surface 120. The peripheral side surface 140 is located between and connected to the first surface 110 and the second surface 120. It should be noted that the edge of the first surface 110, the edge of the peripheral side surface 140, and the edge of the second surface 120 are connected to form the outer surface of the edge region 130.

[0097] A portion of the first sealant 210 and a portion of the second sealant 220 extend to the peripheral side surface 140, and the portions of the first sealant 210 and the second sealant 220 extending to the peripheral side surface 140 are connected thereto. By connecting the first sealant 210 and the second sealant 220 at the peripheral side surface 140 to form a sealed structure, liquid or moisture can be prevented from entering the dimming diaphragm 100 from the peripheral side surface 140, thereby ensuring the safety and stability of the dimming device.

[0098] Furthermore, the side of the first sealant 210 away from the peripheral side 140 covers a portion of the first surface 110, and the side of the second sealant 220 away from the peripheral side 140 covers a portion of the second surface 120, thereby increasing the contact area between the first sealant 210 and the second sealant 220 and the edge area 130, preventing the first sealant 210 from detaching in the area of ​​the first surface 110 and the second sealant 220 from detaching in the area of ​​the peripheral side 140 near the second surface 120, and improving the stability of the adhesion between the first sealant 210 and the second sealant 220 and the edge area 130.

[0099] Furthermore, a portion of the third sealant 310 and a portion of the fourth sealant 320 extend to the peripheral side surface 140, and the portions of the third sealant 310 and the fourth sealant 320 extending to the peripheral side surface 140 are connected thereto. By connecting the third sealant 310 and the fourth sealant 320 at the peripheral side surface 140 to form a sealed structure, liquid or moisture can be prevented from entering the dimming diaphragm 100 from the peripheral side surface 140, thereby ensuring the safety and stability of the dimming device.

[0100] Furthermore, the side of the third sealant 310 away from the peripheral side 140 covers a portion of the first surface 110, and the side of the fourth sealant 320 away from the peripheral side 140 covers a portion of the second surface 120, thereby increasing the contact area between the third sealant 310 and the fourth sealant 320 and the edge area 130, which can not only effectively prevent the third sealant 310 from delaminating in the area of ​​the first surface 110, but also prevent the fourth sealant 320 from delaminating in the area of ​​the second surface 120, but also improve the stability of the adhesion between the third sealant 310 and the fourth sealant 320 and the edge area 130.

[0101] like Figure 4 As shown, in some embodiments of this application, if the first sealant 210 and the second sealant 220 are connected to each other, overlapped or bonded on the peripheral side 140, that is, the first sealant 210 and the second sealant 220 partially overlap on the peripheral side 140, then the width of the connection between the first sealant 210 and the second sealant 220 on one side of the peripheral side 140 is greater than the thickness of the first sealant 210 or the thickness of the second sealant 220. That is, a portion of the connection between the first sealant 210 and the second sealant 220 extends to the side of the peripheral side 140 away from the center portion, so as to form an integral "Y"-shaped first sealing member 200 by connecting the first sealant 210 and the second sealant 220 on one side of the peripheral side 140, thereby forming a seal on the edge of the dimming film 100. In other words, the first seal 200 forms a "Y" shape in the edge region 130. The "Y"-shaped first seal 200 can offset stress through its own extensibility, thereby reducing or even eliminating its own wrinkles and improving the overall sealing efficiency and performance of the dimming device. Therefore, this "Y"-shaped sealing knot can not only effectively seal the edge region 130, but also ensure the sealing quality. Moreover, the adhesive layer at irregular edges is less prone to wrinkles, ensuring the overall aesthetics and sealing performance of the dimming device, effectively preventing the side edges of the dimming diaphragm 100 from contacting the external environment, thereby improving the service life of the dimming device.

[0102] Furthermore, the third sealant 310 and the fourth sealant 320 are connected to each other, overlapped, or bonded on the peripheral side 140. That is, the connection principle of the third sealant 310 and the fourth sealant 320 on the peripheral side 140 is the same as the connection principle of the first sealant 210 and the second sealant 220 described above, and will not be repeated here. In other words, the second sealant 300 forms a "Y" shape in the edge region 130.

[0103] like Figure 5 As shown, in some embodiments of this application, the first sealant 210 and the second sealant 220 are integrally connected on the peripheral side 140 to form a "U"-shaped first seal 200, and the third sealant 310 and the fourth sealant 320 can also be integrally connected on the peripheral side 140 to form a "U"-shaped second seal 300, thereby forming a seal on the edge of the dimming diaphragm 100. Since the "U"-shaped sealing structure forms a wrap around the edge area 130, the sealing quality of the edge area 130 can be guaranteed, preventing external moisture from entering the edge area 130.

[0104] Understandably, by setting the first seal 200 and the second seal 300 in a “U” or “Y” shaped sealing structure in the edge area 130 to cover the peripheral side 140, the edge of the dimming diaphragm 100 is prevented from being directly exposed to the environment. This increases the difficulty for moisture in the environment to enter the dimming diaphragm 100, reduces the probability of moisture contacting the electrochromic layer 170 in the dimming diaphragm 100, reduces the risk of color change failure of the electrochromic material, and thus prolongs the service life of the dimming diaphragm 100.

[0105] like Figure 8 As shown, in some embodiments of this application, the dimming device includes a first substrate layer 1300 and a second substrate layer 1600. The first substrate layer 1300 is disposed on the side of the first substrate layer 150 away from the second substrate layer 190, and the second substrate layer 1600 is disposed on the side of the second substrate layer 190 away from the first substrate layer 150.

[0106] Along the thickness direction, the first substrate layer 1300 and the second substrate layer 1600 completely cover the dimming film 100. In some embodiments, the projections of the first substrate layer 1300 and the second substrate layer 1600 along the thickness direction completely overlap.

[0107] In this embodiment, the distance from the edge of the first substrate layer 1300 or the edge of the second substrate layer 1600 to the edge of the dimming diaphragm 100 is the sealing width L, which is the distance between the edge of the dimming device and the edge of the dimming diaphragm 100.

[0108] Because the sealing width varies in different areas of the dimming device, with some areas having a larger sealing width and others a smaller one, the smaller sealing width often fails to guarantee a sufficient seal under the same sealing conditions, thus failing to effectively seal the edge of the dimming diaphragm 100. For example, if the sealing width L < 30mm, the smaller width allows moisture to easily penetrate the dimming device. If the first sealing element 200 and the second sealing element 300 are spaced apart in the edge area 130, a sealing gap will be formed, reducing the sealing effect and making it difficult to meet the requirements for sealing reliability.

[0109] Based on this, in some embodiments, when the sealing width of this application satisfies the following relationship: L≥30mm, the first sealing member 200 and the second sealing member 300 are spaced apart. It can be understood that, at this time, the sealing width L is relatively long, and the first sealing member 200 and the second sealing member 300 can be spaced apart, which can effectively block external liquids or water vapor, and also block precipitated substances.

[0110] Based on this, such as Figure 8 As shown, in some embodiments of this application, when the sealing width L satisfies the following relationship: L < 30 mm, one end of the first sealing member 200 and one end of the second sealing member 300 overlap, thereby forming an integral sealing structure in the edge area 130 through the first sealing member 200 and the second sealing member 300, and the edge area 130 can be completely sealed through the first sealing member 200 and the second sealing member 300, thereby ensuring the sealing quality of the edge area 130 and the sealing quality of the dimming diaphragm 100.

[0111] It is understandable that by using the first sealing member 200 and the second sealing member 300 to perform corresponding sealing at different sealing widths in the edge area 130 of the dimming diaphragm 100, not only can the sealing quality of the dimming diaphragm 100 be guaranteed to meet the corresponding effective sealing of different areas of the edge area 130 of the dimming diaphragm 100, but also the encapsulation diversity of the edge area 130 of the dimming diaphragm 100 can be achieved.

[0112] Furthermore, it should be noted that since the dimming diaphragm 100 has a multi-layered structure, when an external force is applied to the dimming device, the layers of the dimming diaphragm 100 may separate from each other. Therefore, when the first sealing member 200 and the second sealing member 300 can cover the edges of the dimming diaphragm 100, the risk of layer separation at the edges of the dimming diaphragm 100 can be reduced, thereby increasing the structural stability of the entire dimming device.

[0113] like Figures 2 to 5As shown, the first groove 131 penetrates the first base layer 150, the first conductive layer 160 and the electrochromic layer 170 along the thickness direction, and exposes a portion of the second conductive layer 180. The portion of the second conductive layer 180 exposed by the first groove 131 forms a first electrode 181, thereby enabling the second conductive layer 180 to be electrically connected to an external power source through the first electrode 181.

[0114] In addition, the second groove 132 penetrates the second base layer 190, the second conductive layer 180 and the electrochromic layer 170 along the thickness direction, and exposes a portion of the first conductive layer 160. The portion of the first conductive layer 160 exposed by the second groove 132 forms the second electrode 161, thereby enabling the second conductive layer 180 to be electrically connected to an external power source through the first electrode 181.

[0115] It is understood that by connecting the first electrode 181 and the second electrode 161 to an external power source, the dimming diaphragm 100 is electrically connected to the external power source.

[0116] In this embodiment, the first surface 110 is disposed on the side of the first base layer 150 away from the second base layer 190, that is, the first surface 110 is located in the edge region of the first base layer 150; the second surface 120 is disposed on the side of the second base layer 190 away from the first base layer 150, that is, the second surface 120 is located in the edge region of the second base layer 190.

[0117] After prolonged use, substances deposited in the electrochromic layer 170 of the dimming device may easily precipitate from the walls of the first groove 131 and / or the second groove 132. If the substances deposited in the electrochromic layer 170 come into contact with the first electrode 181 or the second electrode 161, it may cause a short circuit in the dimming device.

[0118] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the edge region 130 is provided with a plurality of spaced through grooves 133. Along the arrangement direction of the first groove 131 and the second groove 132, a through groove 133 is provided between adjacent first grooves 131 and second grooves 132, and the adjacent first grooves 131 and second grooves 132 are connected by the through groove 133.

[0119] The through-slot 133 penetrates the first substrate layer 150, the first conductive layer 160, the electrochromic layer 170, the second conductive layer 180, and the second substrate layer 190. It should be noted that in the aforementioned embodiment, along the arrangement direction of the first groove 131 and the second groove 132, a portion of the electrochromic layer 170 is exposed to the first groove 131 and the second groove 132. Substances deposited from the electrochromic layer 170 risk contacting the first electrode 181 through the first groove 131 and the second electrode 161 through the second groove 132. Therefore, this application provides a through-slot between the first groove 131 and the second groove 132 to remove the electrochromic layer 170 between the first groove 131 and the second groove 132, thereby preventing substances deposited from the electrochromic layer 170 from contacting the first electrode 181 and the second electrode 161, thus ensuring the safety and stability of the dimming device.

[0120] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the dimming device further includes a first busbar 900 and a second busbar 1000. The first busbar 900 is disposed on the first surface 110 of the edge region 130 and extends along the arrangement direction of the first groove 131 and the second groove 132. The second busbar 1000 is disposed on the second surface 120 of the edge region 130 and extends along the arrangement direction of the first groove 131 and the second groove 132.

[0121] A portion of the first busbar 900 is disposed in the first groove 131, and the first busbar 900 located in the first groove 131 is at least partially connected to the first electrode 181, thereby electrically connecting the second conductive layer 180 and the first busbar 900. Additionally, at least a portion of the first sealant 200 (here, at least a portion of the first sealant 200 refers to the first sealant 210) and at least a portion of the second sealant 300 (here, at least a portion of the second sealant 300 refers to the third sealant 310) are respectively disposed on one side of the first surface 110, covering the first busbar 900, so that the first busbar 900 is fixed to the first surface 110 by the first sealant 200 and the second sealant 300 disposed on the first surface 110, thereby ensuring the stability of the connection between the first busbar 900 and the dimming diaphragm 100. Meanwhile, the first sealing element 200 and the second sealing element 300 disposed on the first surface 110 form a sealing protection for the first busbar 900, so as to prevent the first busbar 900 from contacting other external conductive carriers, thereby ensuring the safety of the dimming device.

[0122] Additionally, a portion of the second busbar 1000 is disposed in the second groove 132, and the second busbar 1000 located in the second groove 132 is at least partially connected to the second electrode 161, thereby electrically connecting the first conductive layer 160 and the second busbar 1000. It should be noted that at least a portion of the first sealant 200 (here, at least a portion of the first sealant 200 refers to the second sealant 220) and at least a portion of the second sealant 300 (here, at least a portion of the second sealant 300 refers to the fourth sealant 320) are respectively disposed on one side of the second surface 120, covering the second busbar 1000, so that the second busbar 1000 is fixed to the second surface 120 by the first sealant 200 and the second sealant 300 disposed on the second surface 120, thereby ensuring the stability of the connection between the second busbar 1000 and the dimming diaphragm 100. Meanwhile, the first seal 200 and the second seal 300 disposed on the second surface 120 form a sealing protection for the second busbar 1000, so as to prevent the second busbar 1000 from contacting other external conductive carriers, thereby ensuring the safety of the dimming device.

[0123] Along the thickness direction, an insulating portion 800 is provided between the first busbar 900 and the second busbar 1000. The insulating portion 800 is disposed in the through groove 133 to separate the first busbar 900 and the second busbar 1000 facing the through groove 133, so as to prevent the first busbar 900 and the second busbar 1000 from contacting each other in the through groove 133 and avoid short circuit.

[0124] For example, along the thickness direction, one side of the insulating portion 800 has a first insulating surface, and the other side of the insulating portion 800 has a second insulating surface. The side of the first busbar 900 facing the insulating portion 800 contacts the first insulating surface, and the side of the second busbar 1000 facing the insulating portion 800 contacts the second insulating surface. Thus, the insulating portion 800 forms an insulating barrier between the first busbar 900 and the second busbar 1000, ensuring the stability and safety of the dimming device.

[0125] In some embodiments of this application, the through-slot 133 penetrates the first conductive layer 160, the electrochromic layer 170, and the second conductive layer 180, and the through-slot 133 also penetrates the first base layer 150 or the second base layer 190.

[0126] It is understood that in some embodiments, the through groove 133 penetrates the first base layer 150, the first conductive layer 160, the electrochromic layer 170, and the second conductive layer 180. In this case, along the arrangement direction of the first groove 131 and the second groove 132, there is also a portion of the second base layer 190 between adjacent first grooves 131 and second grooves 132. The second base layer 190 can form an insulating barrier between the first busbar 900 and the second busbar 1000, which can prevent the first busbar 900 and the second busbar 1000 from contacting each other and ensure the stability of the dimming device.

[0127] In other embodiments, the through groove 133 penetrates the second base layer 190, the second conductive layer 180, the electrochromic layer 170, and the first conductive layer 160. In this case, along the arrangement direction of the first groove 131 and the second groove 132, there is also a portion of the second base layer 190 between adjacent first grooves 131 and second grooves 132. The second base layer 190 can form an insulating barrier between the first busbar 900 and the second busbar 1000, which can prevent the first busbar 900 and the second busbar 1000 from contacting each other and ensure the stability of the dimming device.

[0128] like Figure 6 As shown, in some embodiments of this application, the dimming device further includes a first lead-out portion 1100 and a second lead-out portion 1200. One end of the first lead-out portion 1100 is disposed in the first groove 131 and electrically connected to the first busbar 900. One end of the second lead-out portion 1200 is disposed in the second groove 132 and electrically connected to the second busbar 1000.

[0129] One end of the first lead-out portion 1100 is received in the first groove 131 and connected to the first busbar 900. The other end of the first lead-out portion 1100 can be connected to an external power source to form an electrical connection between the first busbar 900 and the external power source. Similarly, one end of the second lead-out portion 1200 is received in the second groove 132 and connected to the second busbar 1000. The other end of the second lead-out portion 1200 can be connected to an external power source to form an electrical connection between the second busbar 1000 and the external power source.

[0130] like Figure 8 As shown, some embodiments of this application provide a dimming device, including a first substrate layer 1300, a first adhesive layer 1400 and the dimming device in any of the above embodiments, a second adhesive layer 1500 and a second substrate layer 1600 stacked sequentially.

[0131] The dimming device further includes a sealing part 1700, which is disposed between the first substrate layer 1300 and the second substrate layer 1600. Specifically, the sealing part 1700 is connected to the first substrate layer 1300 on the side facing the first substrate layer 1300 and to the second substrate layer 1600 on the side facing the second substrate layer 1600. The first adhesive layer 1400 and the second adhesive layer 1500 are respectively connected to the sealing part 1700 on the side facing the sealing part 1700, so that the first substrate layer 1300, the sealing part 1700 and the second substrate layer 1600 enclose a sealed space, in which the dimming device is housed.

[0132] Specifically, both the first substrate layer 1300 and the second substrate layer 1600 are transparent structures. For example, the first substrate layer 1300 and the second substrate layer 1600 can be transparent glass, transparent acrylic sheets, or transparent PVC sheets. Preferably, the first substrate layer 1300 and the second substrate layer 1600 are glass, and by sandwiching the dimming device between the first substrate layer 1300 and the second substrate layer 1600, 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.

[0133] The material of the sealing part 1700 includes one of the adhesives conventional in the art that have the effect of blocking water and oxygen, such as pressure-sensitive adhesive, hot melt adhesive, UV-curable adhesive, thermosetting adhesive or UV-heated dual-curing adhesive. It is understood that in some cases, the sealing part 1700 may use the same material as the first adhesive layer 1400 and the second adhesive layer 1500.

[0134] Additionally, a shielding layer is provided on the surface of the first substrate layer 1300 and / or the second substrate layer 1600 corresponding to the edge area 130 of the dimming device. The shielding layer can be located on the inner or outer surface of the first substrate layer 1300 and / or the second substrate layer 1600; the shielding layer can be made of shielding materials such as metal or black ink. To prevent users from directly seeing the edge area 130 of the dimming device through the transparent first substrate layer 1300 and / or the second substrate layer 1600, and to improve the overall appearance of the device, a shielding layer is provided at the edge of the first substrate layer 1300 and / or the second substrate layer 1600. This shielding layer also blocks the busbar and sealant of the dimming device, thereby enhancing the aesthetics of the dimming device.
