[0040] 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 terms used in the specification of the template are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] As Figures 1 to 3 Some embodiments of the present application provide a light adjusting device, mainly used to meet the sealing requirements of different areas of the edge portion of the light adjusting film.

[0042] The light adjusting device includes a light adjusting film 100 and a colloid.

[0043] The light adjusting film 100 has an edge portion 110, and the colloid is arranged on the edge portion 110, and the colloid includes a first colloid portion 210 and a second colloid portion 220.

[0044] The first colloid part 210 includes a first protective layer 211 and a first water absorption layer 212, and the first water absorption layer 212 is fixed between the first protective layer 211 and the light-adjusting film sheet 100, so as to adsorb the water vapor close to the light-adjusting film sheet 100 through the first water absorption layer 212 and preliminarily block the water vapor perpendicular to the light-adjusting film sheet 100 through the first protective layer 211, thereby forming a seal at the edge part 110 of the light-adjusting film sheet 100 to prevent the external water vapor from entering the light-adjusting film sheet 100 from the edge part 110.

[0045] In the embodiment, the first protective layer 211 and the first water absorption layer 212 are arranged in a stacked manner, and the first protective layer 211 and the first water absorption layer 212 overlap in the projection in the direction perpendicular to the light-adjusting film sheet 100.

[0046] In addition, the second colloid part 220 includes a second protective layer 221, and the second protective layer is fixed to the surface of the light-adjusting film sheet 100, so as to preliminarily block the edge part 110 of the light-adjusting film sheet 100 through the second protective layer 221 to prevent the external water vapor from entering the light-adjusting film sheet 100 from the area covered by the second protective layer 221.

[0047] It is worth noting that, since the first colloid part 210 includes the first protective layer 211 and the first water absorption layer 212 and the second colloid part 220 includes the second protective layer 221, it can be understood that the first colloid part 210 has an additional first water absorption layer 212 compared with the second colloid part 220, that is, the water-blocking effect of the first colloid part 210 on the edge part 110 is better than the sealing effect of the second colloid part 220 on the edge part 110.

[0048] In addition, it should be noted that, since the first colloid part 210 has an additional first water absorption layer 212 compared with the second colloid part 220, that is, the cost of the first colloid part 210 is higher than that of the second colloid part 220, although the sealing quality of the first colloid part 210 on the edge part 110 is higher than that of the second colloid part 220, if the first colloid part 210 is used to seal the edge part 110, the sealing cost of the edge part 110 will be increased, and if the second colloid part 220 is used to seal the edge part 110, the sealing quality of the edge part 110 will be poor.

[0049] Optionally, the first protective layer 211 and the second protective layer 221 can play the role of bearing and blocking, and can be one or more of polyethylene (PE), polypropylene (PP), polyester (PET), polyvinyl chloride (PVC), polyurethane (PU), nylon (PA), metal foil, and fiberglass.

[0050] The first water absorption layer 212 can be a polymer water absorption material, and can be one or more of polyurethane (PU), epoxy resin, thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), polyacrylic acid (PAA), polyethylene imine (PEIE), and ethylene-vinyl acetate (EVA).

[0051] The present application uses a colloid with stronger water absorption to bond and cover the area where the edge of the light control film 100 is more vulnerable to water vapor intrusion, and uses ordinary colloid to bond the other parts with relatively low risk of water vapor intrusion. In this way, the waterproof requirements of specific areas can be met, and the use cost of the overall colloid can be effectively reduced.

[0052] Specifically, the present application adopts a differentiated sealing method in different areas of the edge portion 110 of the light control film 100. For areas with relatively high risk of water vapor intrusion, the first colloid portion 210 is used to enhance protection and effect and avoid water vapor intrusion. In addition, for areas with relatively low risk of water vapor intrusion, the second colloid portion 220 is used for sealing, that is, by providing the second colloid portion 220, the protection effect of the second colloid portion 220 on the edge portion 110 is ensured, so that the sealing requirements of each area of the light control film 100 are met, and the sealing cost of the edge portion 110 of the light control film 100 is reduced.

[0053] As shown in FIG. 1, the light control film 100 includes a first colloid portion 210 and a second colloid portion 220. Figure 3As shown, in some embodiments, the first colloidal portion 210 further includes a first barrier layer 213, which is stacked on the side of the first protective layer 211 away from the first absorbent layer 212, so as to further block water vapor in the thickness direction perpendicular to the first protective layer 211, and further prevent external water vapor from entering the dimming film 100 from the thickness direction of the first colloidal portion 210.

[0054] In this embodiment, the first barrier layer 213, the first absorbent layer 212 and the first protective layer 211 are overlapped along the thickness direction of the dimming film 100 to ensure the waterproof effect of the first colloid portion 210 on the edge portion 110.

[0055] The first barrier layer 213 is a water and oxygen barrier layer, and the water and oxygen barrier material in the water and oxygen barrier layer can be one or more of polyethylene terephthalate (PET), polyimide (PI), polyethylene-vinyl acetate copolymer (EVA), polyester, fluorinated ethylene (FEP), and polypropylene (PP).

[0056] like Figures 2 to 7 As shown, in some embodiments, the dimming film 100 includes a first base layer 120, a first conductive layer 130, a dimming layer 140, a second conductive layer 150, and a second base layer 160 stacked sequentially.

[0057] The first substrate 120 and the second substrate 160 are both transparent substrates. The "transparent substrate" is an optically transparent material, which can be a flexible substrate material, such as polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymer, or cellulose triacetate.

[0058] In addition, the first conductive layer 130 and the second conductive layer 150 are both transparent conductive layers, and the material of the transparent conductive layer can be any transparent conductive material known to those skilled in the art, for example, Indium-Tin Oxide (ITO), Aluminum Zinc Oxide (AZO), Fluorine Doped Tin Oxide (FTO), silver nanowire, graphene, carbon nanotube, metal mesh, or silver nanoparticles.

[0059] In some embodiments of the present application, as shown in Figure 1 The edge portion 110 is provided with first grooves 111 and second grooves 112 arranged alternately, and the number of the first grooves 111 and the second grooves 112 can be one, two, or any number of two or more, which can be set according to actual conditions.

[0060] In addition, the first grooves 111 penetrate through the first base layer 120, the first conductive layer 130, and the light-adjusting layer 140, and expose part of the second conductive layer 150, so as to be electrically connected with an external power supply through the exposed part of the second conductive layer 150.

[0061] The second grooves 112 penetrate through the second base layer 160, the second conductive layer 150, and the light-adjusting layer 140, and expose part of the first conductive layer 130, so as to be connected with an external power supply through the exposed part of the first conductive layer 130, thereby connecting the first conductive layer 130 and the second conductive layer 150 with the external power supply, respectively.

[0062] As shown in Figure 4 and Figure 5 The first gel portion 210 and / or the second gel portion 220 cover the surface corresponding to the first grooves 111. Specifically, the surface corresponding to the first grooves 111 is covered by the first gel portion 210, or the surface corresponding to the first grooves 111 is covered by the second gel portion 220, or the surface corresponding to the first grooves 111 is covered by the first gel portion 210 and the second gel portion 220 in cooperation.

[0063] The first gel portion 210 and / or the second gel portion 220 cover the surface corresponding to the second grooves 112. Specifically, the surface corresponding to the second grooves 112 is covered by the first gel portion 210, or the surface corresponding to the second grooves 112 is covered by the second gel portion 220, or the surface corresponding to the second grooves 112 is covered by the first gel portion 210 and the second gel portion 220 in cooperation.

[0064] In the above embodiments of this application, the first colloidal portion 210 adsorbs moisture and forms a barrier to prevent moisture from entering the dimming film 100 from the inner wall of the first groove 111 or the inner wall of the second groove 112, thereby reducing the risk of the electrochromic material in the dimming layer 140 being corroded by moisture. In addition, the second colloidal portion 220 blocks moisture, preventing moisture from entering the dimming film 100 from the inner wall of the first groove 111 or the inner wall of the second groove 112, thereby reducing the risk of the electrochromic material in the dimming layer 140 being corroded by moisture and thus extending the service life of the dimming film 100.

[0065] like Figure 4 As shown, in some embodiments, the first colloid portion 210 includes a first adhesive layer 214 and a second adhesive layer 215. The first adhesive layer 214 includes a first sub-protective layer 2141 and a first sub-absorbent layer 2142. The first sub-absorbent layer 2142 is disposed on the side of the first sub-protective layer 2141 facing the dimming film 100, and the first sub-absorbent layer 2142 covers the surface corresponding to the first groove 111 and at least a portion of the side surface of the dimming film. In addition, the second adhesive layer 215 includes a second sub-protective layer 2151 and a second sub-absorbent layer 2152. The second sub-absorbent layer 2152 is disposed on the side of the second sub-protective layer 2151 facing the dimming film 100, and the second sub-absorbent layer 2152 covers the surface corresponding to the second groove 112 and at least part of the side surface of the dimming film, so that the first sub-absorbent layer 2142 and the second sub-absorbent layer 2152 respectively adsorb water vapor to form a barrier effect, preventing water vapor from entering the dimming film 100 from the first sub-absorbent layer 2142 and the second sub-absorbent layer 2152.

[0066] In some embodiments, the first colloid portion 210 includes a first adhesive layer 214 and a second adhesive layer 215. The first adhesive layer 214 and the second adhesive layer 215 are connected to form a connecting portion 230 on the side of the dimming film. Specifically, the connecting portion 230 has a connecting end, which is the end of the connecting portion away from the dimming film. The distance between the connecting end and the side of the dimming film 100 is X, which satisfies: 0 < X ​​≤ 30 mm.

[0067] In this embodiment, the first adhesive layer 214 is disposed on one side of the dimming film 100 in the thickness direction, and the second adhesive layer 215 is disposed on the other side of the dimming film 100 in the thickness direction, and the first adhesive layer 214 and the second adhesive layer 215 are connected to each other on the side of the dimming film 100.

[0068] See Figure 4As shown, in order to improve the strength of the sealing of the side surface of the light control film sheet 100, a length is provided between the end of the connecting portion and the side surface of the light control film sheet 100, and the length is the spacing X between the connecting end of the connecting portion and the side surface of the light control film sheet 100. When X is too small, the first adhesive layer 214 and the second adhesive layer 215 are easily separated from each other, and cannot form stable adhesion. In addition, when water vapor invades the light control film sheet 100 along the first direction, especially when water vapor invades the light control film sheet 100 along the bonding surface of the first adhesive layer 214 and the second adhesive layer 215, a longer water vapor invasion path cannot be formed, thereby increasing the risk of water vapor invasion. When X is too large, the proportion of the non-color-changing area of the light control film sheet 100 is increased. Here, the proportion of the non-color-changing area is the ratio of the non-color-changing area of the light control film sheet 100 to the total area of the light control film sheet 100. When the proportion of the non-color-changing area is large, the proportion of the color-changing area that can realize the light control function is correspondingly reduced, thereby reducing the use experience of the light control film sheet 100.

[0069] In some embodiments, the value of X is in the range of 0 < X ≤ 30 mm, for example, X can be 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 7 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., which can be set according to actual conditions.

[0070] In some embodiments, the first sub-water absorption layer 2142 at least partially covers the first groove 111, and the second sub-water absorption layer 2152 at least partially covers the edge portion 110 of the second base layer 160. The first sub-water absorption layer 2142 and the second sub-water absorption layer 2152 are bonded on the side surface to form part of the connecting portion 230, so as to improve the stability of the connection between the first sub-water absorption layer 2142 and the second sub-water absorption layer 2152, and the stability of the connection between the first adhesive layer 214 and the second adhesive layer 215.

[0071] In some embodiments, the second sub-water absorption layer 2152 at least partially covers the second groove 112, and the first sub-water absorption layer 2142 at least partially covers the edge portion 110 of the first base layer 120. The first sub-water absorption layer 2142 and the second sub-water absorption layer 2152 are bonded on the side surface to form part of the connecting portion 230, so as to improve the stability of the connection between the first sub-water absorption layer 2142 and the second sub-water absorption layer 2152, and the stability of the connection between the first adhesive layer 214 and the second adhesive layer 215.

[0072] In this embodiment, a portion of the connecting portion 230 is formed by bonding the first sub-absorbent layer 2142 and the second sub-absorbent layer 2152 on the side to cover the edge portion 110, thereby preventing the edge portion 110 from being directly exposed to the environment. This increases the difficulty for moisture in the environment to enter the dimming film 100, reduces the probability of moisture contacting the dimming layer 140 in the dimming film 100, reduces the risk of color change failure of the electrochromic material, and thus prolongs the service life of the dimming film 100.

[0073] like Figure 6 As shown, in some embodiments, the second colloid portion 220 includes a third adhesive layer 222 and a fourth adhesive layer 223. The third adhesive layer 222 covers the surface corresponding to the first groove 111 and at least a portion of the side surface of the dimming film 100, and the fourth adhesive layer 223 covers the surface corresponding to the second groove 112 and at least a portion of the side surface of the dimming film 100. In this embodiment, by providing the third adhesive layer 222 and the fourth adhesive layer 223, moisture is prevented from entering the dimming film 100 from the inner wall of the first groove 111 or the inner wall of the second groove 112, reducing the risk of the electrochromic material in the dimming layer 140 being corroded by moisture, thereby extending the service life of the dimming film 100. Optionally, the projections of the third adhesive layer 222 and the fourth adhesive layer 223 in the thickness direction of the dimming film 100 overlap to ensure that the third adhesive layer 222 and the fourth adhesive layer 223 achieve a common seal at the edge portion 110.

[0074] Optionally, in some embodiments, the third adhesive layer 222 and the fourth adhesive layer 223 extend to the side of the dimming diaphragm 100 and are connected to each other. The third adhesive layer 222 and the fourth adhesive layer 223 can be directly bonded together, thereby improving the sealing effect of the dimming diaphragm 100. This sealing method can be applied to dimming diaphragms 100 of different shapes, with a wide range of applications and high flexibility.

[0075] In some embodiments of this application, the first colloid portion 210 is disposed in the first region of the dimming film 100, and the second colloid portion 220 is disposed in the second region of the dimming film, with the first region and the second region being disposed adjacent to each other; at the adjoining location of the first region and the second region, the end of the first colloid portion 210 overlaps with the end of the second colloid portion 220 to form an overlapping portion.

[0076] In this embodiment, by connecting the first colloidal portion 210 and the second colloidal portion 220 to form a continuous colloidal structure, moisture is prevented from entering the dimming layer 140 at the point where the first colloidal portion 210 and the second colloidal portion 220 are disconnected, thereby further improving the sealing quality of the edge portion 110. Furthermore, by sealing the first region and the second region separately, not only can the sealing cost of the dimming film 100 be reduced, but the encapsulation effect of different regions of the edge portion 110 of the dimming film 100 can also be guaranteed, improving the sealing quality of the dimming device.

[0077] In some embodiments of this application, the edge portion is provided with a notch 113, the notch 113 penetrates the first base layer 120, the first conductive layer 130, the dimming layer 140, the second conductive layer 150 and the second base layer 160, and the notch 113 communicates with the first groove 111 and the second groove 112, and the overlapping portion 240 is located in the notch 113.

[0078] like Figure 7 As shown, in this embodiment, the edge portion 110 is provided with a notch 113, which penetrates the first conductive layer 130, the dimming layer 140, and the second conductive layer 150. Furthermore, the notch 113 also penetrates the first base layer 120 and / or the second base layer 160. Adjacent first grooves 111 and second grooves 112 are connected through the notch 113. It should be noted that the thickness at the notch 113 is less than the thickness of the first groove 111 or the second groove 112. The first colloidal portion 210 and the second colloidal portion 220 overlap to form an overlapping portion 240, which is located within the notch 113. This avoids the overlapping portion 240 being located elsewhere, which would result in an excessively thick overlapping portion, thus ensuring the uniformity of the thickness of the edge portion 110 and preventing the edge portion 110 from cracking under stress.

[0079] like Figures 4 to 6 As shown, in some embodiments, the dimming device further includes a first busbar 300 and a second busbar 400, the length directions of the first busbar 300 and the second busbar 400 being parallel to the arrangement direction of the first groove 111 and the second groove 112.

[0080] In some embodiments, the first busbar 300 and the second busbar 400 are disposed between the colloid and the dimming film 100. In other embodiments, the second busbar 400 is disposed between the colloid and the dimming film 100. In the above embodiments, the first busbar 300 and the second busbar 400 are respectively connected to the dimming film 100 through the colloid to ensure the stability of the first busbar 300 and the second busbar 400 on the dimming film 100.

[0081] In addition, the first bus bar 300 is arranged on the side of the second conductive layer 150 away from the second substrate layer 160, and the first bus bar 300 is at least partially connected to the second conductive layer 150 in the first groove 111. The second bus bar 400 is arranged on the side of the first conductive layer 130 away from the first substrate layer 120, and the second bus bar 400 is at least partially connected to the first conductive layer 130 in the second groove 112. Thus, the first bus bar 300 is electrically connected to the second conductive layer 150, and the second bus bar 400 is electrically connected to the first conductive layer 130. By forming electrical connections between the first bus bar 300 and the second bus bar 400 and an external power supply, the dimming film 100 is electrically connected to the external power supply.

[0082] As shown in FIG. 1, some embodiments of the present application provide a dimming device, which includes a first substrate layer 500, a first adhesive layer 600, and a dimming device according to any one of the embodiments described above, a second adhesive layer 700, and a second substrate layer 800. Figure 8

[0083] In some embodiments, the dimming device further includes a sealing member 900, which is arranged between the first substrate layer 500 and the second substrate layer 800 and surrounds the periphery of the dimming device. That is, one side of the sealing member 900 facing the first substrate layer 500 is connected to the first substrate layer 500, and the other side of the sealing member 900 facing the second substrate layer 800 is connected to the second substrate layer 800. The sides of the first adhesive layer 600 and the second adhesive layer 700 facing the sealing member 900 are respectively connected to the sealing member 900. Thus, a sealed space is formed by the first substrate layer 500, the sealing member 900, and the second substrate layer 800, and the dimming device is accommodated in the sealed space.

[0084] Specifically, the first substrate layer 500 and the second substrate layer 800 are both transparent structures. For example, the first substrate layer 500 and the second substrate layer 800 can be transparent glass, transparent acrylic plate, or transparent PVC plate, etc. Preferably, the first substrate layer 500 and the second substrate layer 800 are glass. The dimming device is formed by sandwiching the dimming device between the first substrate layer 500 and the second substrate layer 800, so as to avoid the dimming film 100 from contacting external moisture and oxygen, thereby improving the service life of the dimming film 100 and the dimming device.

[0085] The material of the sealing member 900 includes conventional adhesives with water and oxygen blocking effects in the art, such as one of pressure-sensitive adhesives, hot-melt adhesives, UV light-cured adhesives, heat-cured adhesives, or UV and heat dual-cured adhesives. It can be understood that, in some cases, the sealing member 900 can be made of the same material as the first adhesive layer 600 and the second adhesive layer 700.

[0086] ​In addition, the surface of the first substrate layer 500 and / or the second substrate layer 800 corresponding to the edge portion 110 of the light-adjusting device is provided with a shielding layer, which can be arranged on the inner surface or the outer surface of the first substrate layer 500 and / or the second substrate layer 800; the shielding layer can be made of a shielding material such as metal or black ink. In order to avoid the user directly seeing the edge portion 110 of the light-adjusting device through the transparent first substrate layer 500 and / or the second substrate layer 800, and to make the appearance of the entire device more beautiful. Therefore, the shielding layer is arranged at the edge of the first substrate layer 500 and / or the second substrate layer 800, and the colloidal part of the light-adjusting device is shielded by the shielding layer, thereby improving the beauty of the light-adjusting device.

[0087] The light-adjusting device or the light-adjusting apparatus in the embodiments of the present application can be applied to different types of light-adjusting products. It can be understood that the light-adjusting product has the functions and beneficial effects of the light-adjusting device or the light-adjusting apparatus in any one of the above-mentioned embodiments, which will not be described here one by one.
