Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

[0034] Unless otherwise specified, the "end surface" described in the present application refers to the surface of the light modulation device along the thickness direction after the light modulation device is placed on a horizontal plane.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments of the present application, the light modulation device comprises a light modulation assembly 100 and a sealing member, specifically, the sealing member is located at the edge area of the light modulation assembly 100, and the sealing member comprises a first sealing member 200 and a second sealing member 300.

[0036] The first sealing member 200 and the second sealing member 300 are attached to the light modulation assembly 100, wherein the first sealing member 200 comprises a first protective layer 210 and a first water absorption layer 220, the first protective layer 210 defines a first boundary, the first water absorption layer 220 is located on the side of the first protective layer 210 facing the light modulation assembly 100, and the first water absorption layer 220 is located within the first boundary; and / or, the second sealing member 300 comprises a second protective layer 310 and a second water absorption layer 320, the second protective layer 310 defines a second boundary, the second water absorption layer 320 is located on the side of the second protective layer 310 facing the light modulation assembly 100, and the second water absorption layer 320 is located within the second boundary.

[0037] Referring to Figure 3 and Figure 4As shown, the first seal 200 and the second seal 300 are both attached to the edge areas of the upper and lower sides of the dimming assembly 100, and the first seal 200 and the second seal 300 both extend partially to the outside of the dimming assembly 100. The first seal 200 and the second seal 300 are connected to the external extension of the dimming assembly 100, thereby sealing the end face of the dimming assembly 100 and preventing external moisture from entering from the end face of the dimming assembly 100.

[0038] In some embodiments, the first sealing member 200 is composed of a first protective layer 210 and a first absorbent layer 220. Specifically, the first absorbent layer 220 is disposed on the side of the first protective layer 210 facing the dimming component 100. The area of ​​the first absorbent layer 220 is smaller than the area of ​​the first protective layer 210. When connected to the dimming component 100, the edge area of ​​the first protective layer 210 is directly connected to the dimming component 100 and covers the first absorbent layer 220, so that the first absorbent layer 220 does not come into contact with the external environment.

[0039] In this embodiment, when moisture penetrates in, the first absorbent layer 220 can quickly and effectively absorb this moisture, preventing it from passing through the first absorbent layer 220 and entering the dimming assembly 100, thereby protecting the dimming assembly 100 from damage. The first absorbent layer 220 is located within the first boundary defined by the first protective layer 210, and the first protective layer 210 can completely cover the first absorbent layer 220, providing an additional protective barrier to block dust, dirt, or other contaminants other than external moisture. Through the multi-layer waterproof sealing structure, the reliability and durability of the first seal 200 are improved.

[0040] Similarly, the second sealing element 300 is composed of a second protective layer 310 and a second absorbent layer 320. Specifically, the second absorbent layer 320 is disposed on the side of the second protective layer 310 facing the dimming component 100. The area of ​​the second absorbent layer 320 is smaller than the area of ​​the second protective layer 310. When connected to the dimming component 100, the edge area of ​​the second protective layer 310 is directly connected to the dimming component 100 and covers the second absorbent layer 320, so that the second absorbent layer 320 does not come into contact with the external environment.

[0041] In this embodiment, when moisture penetrates, the second absorbent layer 320 can quickly and effectively absorb this moisture, preventing it from passing through the second absorbent layer 320 and entering the dimming assembly 100, thereby protecting the dimming assembly 100 from damage. The second absorbent layer 320 is located within the second boundary defined by the second protective layer 310, which can completely cover the second absorbent layer 320, providing an additional protective barrier to block dust, dirt, or other contaminants other than external moisture. Through the multi-layer waterproof sealing structure, the reliability and durability of the second seal 300 are improved.

[0042] See Figure 3 and Figure 4 As shown, the first seal 200 and the second seal 300 extend from the end face of the dimming assembly 100. At the end face of the dimming assembly 100, the first protective layer 210 and the second protective layer 310 are connected. Since the first absorbent layer 220 is located within the first boundary of the first protective layer 210 and the second absorbent layer 320 is located within the second boundary of the second protective layer 310, after the first protective layer 210 and the second protective layer 310 are connected, the first absorbent layer 220 and the second absorbent layer 320 are covered inside, thereby preventing external moisture from passing through the first absorbent layer 220 and the second absorbent layer 320 and entering the dimming assembly 100.

[0043] In this embodiment, the first protective layer 210 and the second protective layer 310 can serve as load-bearing and protective materials, and can be one or more of polyethylene (PE), polypropylene (PP), polyester (PET), polyvinyl chloride (PVC), polyurethane (PU), nylon (PA), metal film, and fiberglass.

[0044] Optionally, the first absorbent layer 220 and the second absorbent layer 320 can be polymer absorbent materials, such as polyurethane (PU), epoxy resin, thermoplastic polyolefin (TPO), polyacrylic acid (PAA), polyethylene imine (PEIE), and polyethylene-vinyl acetate copolymer (EVA), or one or more of these.

[0045] The dimming assembly 100 includes a first surface and a second surface. A first seal 200 is partially attached to the first surface, a second seal 300 is partially attached to the second surface, and the remaining portions of the first seal 200 and the remaining portions of the second seal 300 are attached to the end face of the dimming assembly 100 to form an extension.

[0046] In some embodiments, a portion of the first seal 200 is fitted to the edge area of ​​the first surface, and a portion of the second seal 300 is fitted to the edge area of ​​the second surface. The remaining portions of the first seal 200 and the second seal 300 extend to the end face of the dimming assembly 100 and are interconnected to form an extension. The extension covers the end face of the dimming assembly 100 to seal the end face of the dimming assembly 100 and prevent external moisture from entering the interior of the dimming assembly 100 from the end face.

[0047] In some embodiments, the extension has an extension end, which is the end of the extension away from the dimming assembly 100, and the distance between the extension end and the end face of the dimming assembly 100 is X, satisfying: 0 < X ​​≤ 30 mm.

[0048] See Figure 3 and Figure 4 As shown, in order to improve the sealing strength of the end face of the dimming component 100, a certain length is provided between the end of the extension and the end face of the dimming component 100. This length is the distance X between the extension end of the extension and the end face of the dimming component 100. When X is too small, the first seal 200 and the second seal 300 can easily separate from each other and cannot form a stable bond. It is also impossible to form a long water vapor intrusion path when water vapor invades the dimming component 100 along the first direction, especially when water vapor invades the dimming component 100 along the bonding surface of the first seal 200 and the second seal 300, thus increasing the risk of water vapor intrusion. When X is too large, it will increase the proportion of the non-color-changing area of ​​the dimming component 100. Here, the proportion of the non-color-changing area is the ratio of the non-color-changing area of ​​the dimming component 100 to the total area of ​​the dimming component 100. When the proportion of the non-color-changing area is large, the proportion of the color-changing area that can realize the dimming function will decrease accordingly.

[0049] Wherein, the value of X ranges from 0 to 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., and can be specifically set according to the actual situation. Preferably, 0.2 mm ≤ X ≤ 5 mm. More preferably, 0.5 mm ≤ X ≤ 3 mm.

[0050] In some embodiments, the dimming assembly 100 includes a third surface located on its end face, a first absorbent layer 220 is attached to the third surface, a second absorbent layer 320 is attached to the third surface, the ends of the first absorbent layer 220 and the ends of the second absorbent layer 320 are connected at the end face of the dimming assembly 100 to cover the third surface, or the first absorbent layer 220 and the second absorbent layer 320 are partially attached at the end face of the dimming assembly 100 to form an attachment portion covering the third surface, and an extension portion covers the attachment portion.

[0051] See Figure 3 and Figure 4 As shown, in one embodiment, when the first seal 200 and the second seal 300 are both set in stages, the first absorbent layer 220 and the second absorbent layer 320 can be set at the edge area of ​​the dimming component 100 first, and then the first protective layer 210 can be attached to the first absorbent layer 220 and the second protective layer 310 can be attached to the second absorbent layer 320 to form a composite seal, thereby improving the sealing performance at the edge area of ​​the dimming component 100 and reducing the overall thickness.

[0052] For example, when the first absorbent layer 220 and the second absorbent layer 320 are waterproof coatings, the first absorbent layer 220 and the second absorbent layer 320 will have a certain fluidity when they are coated but not cured. When they are connected with the first protective layer 210 and the second protective layer 310 extending to the outside of the dimming component 100, the first protective layer 210 and the second protective layer 310 will put pressure on the waterproof coating, causing the waterproof coating to spread further. The surface adhesion between the waterproof coating and the dimming component 100 will be higher, and the thickness of the waterproof coating will also decrease during the spreading process. This changes the position of the first absorbent layer 220 and the second absorbent layer 320 after curing, and at the same time makes the overall thickness of the first sealing structure 200 and the second sealing structure 300 thinner.

[0053] In some embodiments of this application, such as Figure 3 As shown, the first absorbent layer 220 and the second absorbent layer 320 can cover only the upper and lower edge areas of the dimming component 100, or cover the peripheral surface of the dimming component 100, i.e., the end face of the dimming component 100, or even... Figure 4 As shown, the first absorbent layer 220 and the second absorbent layer 320 can extend to the extension position to form an integral bonding part, at which time the first absorbent layer 220 and the second absorbent layer 320 are connected.

[0054] In some embodiments, the dimming assembly 100 includes a first conductive substrate 110, a dimming dielectric layer 120, and a second conductive substrate 130. The first conductive substrate 110, the dimming dielectric layer 120, and the second conductive substrate 130 are stacked sequentially. The first conductive substrate 110 includes a first base layer 111 and a first conductive layer 112. The first conductive layer 112 is connected to the dimming dielectric layer 120, and the first base layer 111 is disposed on the side of the first conductive layer 112 away from the dimming dielectric layer 120. The second conductive substrate 130 includes a second base layer 131 and a second conductive layer 132. The second conductive layer 132 is connected to the dimming dielectric layer 120, and the second base layer 131 is disposed on the side of the second conductive layer 132 away from the dimming dielectric layer 120.

[0055] Both the first substrate layer 111 and the second substrate layer 131 are transparent substrates. The "transparent substrate" is an optically transparent material, specifically a flexible substrate material, such as polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymers, or cellulose triacetate. The first substrate layer 111 and the second substrate layer 131 can also be glass substrates.

[0056] In addition, both the first conductive layer 112 and the second conductive layer 132 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.

[0057] See Figure 1 and Figure 2 As shown, the edge region of the dimming assembly 100 is further provided with a first groove 410 and a second groove 420. The first groove 410 penetrates the first conductive substrate 110 and the dimming medium layer 120, and at least a portion of the first seal 200 covers the first groove 410. The second groove 420 penetrates the second conductive substrate 130 and the dimming medium layer 120, and at least a portion of the second seal 300 covers the second groove 420.

[0058] The first groove 410 penetrates the first conductive substrate 110 and the dimming dielectric layer 120, and the second groove 420 penetrates the second conductive substrate 130 and the dimming dielectric layer 120, thereby exposing the first conductive substrate 110 and the second conductive substrate 130. This facilitates the electrical connection between the second conductive substrate 130 and the outside through the first groove 410, and the electrical connection between the first conductive substrate 110 and the outside through the second groove 420. At this time, a portion of the first sealing member 200 covers the first groove 410, and a portion of the second sealing member 300 covers the second groove 420. This seals the sidewalls of the first groove 410 and the second groove 420, preventing moisture from entering the dimming dielectric layer 120 through the sidewalls of the first groove 410 and / or the second groove 420, thus affecting the function of the dimming dielectric layer 120 and reducing the service life of the dimming assembly 100.

[0059] See Figure 3 and Figure 4As shown, the dimming assembly 100 also includes a first busbar 140 and a second busbar 150. At least a portion of the first busbar 140 is disposed on the side of the second conductive substrate 130 near the dimming medium layer 120 through a first groove 410. At least a portion of the second busbar 150 is disposed on the side of the first conductive substrate 110 near the dimming medium layer 120 through a second groove 420. Furthermore, a first seal 200 covers the first busbar 140, and a second seal 300 covers the second busbar 150.

[0060] In some embodiments, a portion of the first busbars 140 are disposed on the side of the second conductive substrate 130 near the dimming dielectric layer 120 via the first groove 410, and another portion of the first busbars 140 are disposed on the side of the first conductive substrate 110 away from the dimming dielectric layer 120. A portion of the second busbars 150 are disposed on the side of the first conductive substrate 110 near the dimming dielectric layer 120 via the second groove 420, and another portion of the second busbars 150 are disposed on the side of the second conductive substrate 130 away from the dimming dielectric layer 120.

[0061] The first busbar 140 and the second busbar 150 can be made of conductive materials well known to those skilled in the art, such as at least one of conductive silver paste, conductive copper paste, conductive carbon paste, nano silver conductive ink, copper foil, copper wire and conductive film.

[0062] By setting the first busbar 140 and the second busbar 150, when the dimming assembly 100 is powered by an external power source, the current can be quickly conducted through the first busbar 140 to the periphery of the second conductive substrate 130, and through the second busbar 150 to the periphery of the first conductive substrate 110, thereby accelerating the color-changing speed of the dimming assembly 100. Furthermore, by covering the first busbar 140 with the first seal 200, corrosion of the first busbar 140 by moisture or other environmental factors can be prevented, thus avoiding impact on its conductivity and consequently affecting the color-changing speed of the dimming assembly 100. Simultaneously, the first seal 200 can enhance the adhesion between the first busbar 140 and the second conductive substrate 130, reducing the probability of localized electrical conduction failure due to partial separation of the first busbar 140 and the second conductive substrate 130, and preventing any impact on the color-changing speed of the dimming assembly 100. Similarly, by covering the second busbar 150 with the second seal 300, the second busbar 150 can be prevented from being corroded by moisture in the environment, which would affect its conductivity and thus affect the color-changing speed of the dimming assembly 100. At the same time, the second seal 300 can also enhance the adhesion between the second busbar 150 and the first conductive substrate 110, reducing the probability of local electrical conduction failure caused by partial separation of the second busbar 150 and the first conductive substrate 110, and avoiding its impact on the color-changing speed of the dimming assembly 100.

[0063] In some embodiments, the first busbar 140 and / or the second busbar 150 are connected to an electrode 500, the electrode 500 is located between the first absorbent layer 220 and the second absorbent layer 320, the first absorbent layer 220 is connected to the side of the electrode 500 facing the first protective layer 210, the second absorbent layer 320 is connected to the side of the electrode 500 facing the second protective layer 310, and the first absorbent layer 220 and the second absorbent layer 320 cover part of the electrode 500.

[0064] See Figure 5 As shown, the first busbar 140 and the second busbar 150 are powered by the electrode 500. In order to ensure the sealing of the connection between the electrode 500 and the first busbar 140 and the second busbar 150, the first sealing member 200 is pasted on the upper surface of the electrode 500 at the position of the electrode 500, the second sealing member 300 is pasted on the lower surface of the electrode 500 at the position of the electrode 500, and the remaining parts of the first sealing member 200 and the remaining parts of the second sealing member 300 are pasted together, thereby achieving the covering of the electrode 500 and preventing external moisture from entering the dimming assembly 100 through the connection between the first sealing member 200 and the electrode 500 and the connection between the second sealing member 300 and the electrode 500.

[0065] Specifically, the first absorbent layer 220 of the first sealing member 200 is connected to the upper surface of the electrode 500, and the second absorbent layer 320 of the second sealing member 300 is connected to the lower surface of the electrode 500. It can be understood that since the area of ​​the first protective layer 210 is larger than that of the first absorbent layer 220, and the area of ​​the second protective layer 310 is larger than that of the second absorbent layer 320, the first protective layer 210 at the edge area of ​​the first absorbent layer 220 is also connected to the upper surface of the electrode 500, and the second protective layer 310 at the edge area of ​​the second absorbent layer 320 is connected to the lower surface of the electrode 500. Correspondingly, the first protective layer 210 at the edge area of ​​the remaining part of the first absorbent layer 220 is connected to the second protective layer 310 at the edge area of ​​the remaining part of the second absorbent layer 320, thereby achieving the covering of the end face of the dimming component 100.
