Description

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

[0003] However, the light modulation material in the light modulation film is extremely sensitive to environmental moisture. Once it comes into contact with moisture, it is easy to cause discoloration, failure and other problems. These problems will accelerate the damage process of the light modulation film, thereby significantly shortening its service life. Therefore, in the packaging process of the light modulation film, it is particularly important to ensure the sealing performance of the edge of the film. However, the edge of the light modulation device usually has an irregular shape, which makes it difficult to achieve complete sealing effect by using a single sealant, thereby affecting the overall sealing performance of the film.

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

[0048] As shown in Figures 1 to 9 Some embodiments of the present application provide a light adjusting device, mainly used for sealing a light adjusting film 100 with irregular edge shape, to ensure the sealing effect and quality of the light adjusting film 100.

[0049] The light adjusting device includes the light adjusting film 100 and a plurality of glues.

[0050] The light adjusting film 100 has a first substrate layer 120, a first conductive layer 130, a light adjusting layer 140, a second conductive layer 150 and a second substrate layer 160 which are sequentially stacked.

[0051] The first substrate layer 120 and the second substrate layer 160 are both transparent substrates, which are optical grade transparent materials, and can be flexible substrate materials such as Polyethylene Glycol Terephthalate (PET), Polycarbonate (PC), Polyimide (PI), cyclic olefin copolymer or cellulose triacetate. The first substrate layer 120 and the second substrate layer 160 can also be glass substrates.

[0052] In addition, the first conductive layer 130 and the second conductive layer 150 are both transparent conductive layers, which can be transparent conductive materials known to those skilled in the art, such as Indium-Tin Oxide (ITO), Aluminum Zinc Oxide (AZO), Fluorine Doped Tin Oxide (FTO), silver nanowire, graphene, carbon nanotube, metal mesh or silver nanoparticles.

[0053] The first substrate layer 120 has a first surface 121, and the second substrate layer 160 has a second surface 161. The first surface 121 and the second surface 161 are arranged opposite to each other along the stacking direction of the light control film 100, and the edge region of the first surface 121 and the edge region of the second surface 161 are connected by the side surface 170. It can be understood that the first surface 121, the second surface 161 and the side surface 170 are connected to form the outer surface of the light control film 100.

[0054] The edge of the light control film 100 often has an irregular shape, such as the edge region 110 of the light control film 100 having a straight edge region and a curved edge region. Therefore, if the edge region 110 of the light control film 100 is to be completely sealed, a continuous sealing structure needs to be used in the straight edge region and the curved edge region, otherwise a weak sealing position is likely to occur at the connection between the straight edge region and the curved edge region, thereby affecting the sealing effect of the light control film 100.

[0055] Along the side surface of the light control film 100, the light control film 100 is provided with a plurality of glue bodies. One end of each glue body is fixed to the edge region of the first surface 121, and the other end extends to the edge region of the second surface 161 through the side surface 170. The end portions of adjacent two glue bodies partially overlap each other to form an overlapping portion 400.

[0056] Specifically, the plurality of glue bodies include a first glue body 200 and a second glue body 300. The first glue body 200 and the second glue body 300 are arranged in the edge region 110 to respectively seal different parts of the edge region 110 of the light control film 100 through the first glue body 200 and the second glue body 300, so as to ensure the sealing quality of different regions of the edge region 110.

[0057] For example, the first glue body 200 seals the straight edge region of the edge region 110, so as to individually seal the straight edge region through the first glue body 200, thereby ensuring the sealing quality of the straight edge region. The second glue body 300 seals the curved edge region, so as to individually seal the curved edge region through the second glue body 300, thereby ensuring the sealing quality of the curved edge region. It can be understood that the different regions of the edge region 110 are respectively sealed by the first glue body 200 and the second glue body 300, which not only ensures the sealing quality of different regions of the edge region 110, but also effectively improves the sealing efficiency. When the first glue body 200 seals the straight edge region and the second glue body 300 seals the curved edge region, the end portion of the first glue body 200 covers the end portion of the second glue body 300.

[0058] In this embodiment, the first colloid 200 and the second colloid 300 are continuously disposed in the edge region 110, and the ends of the first colloid 200 and the second colloid 300 overlap each other to form an overlapping portion 400. The first colloid 200 and the second colloid 300 are connected to form a continuous closed-loop sealing structure in the edge region 110, thereby forming a complete seal on the edge region 110. This not only reduces the difficulty of sealing the dimming film 100, but also ensures the sealing quality of different areas, thereby preventing external moisture from entering the dimming film 100 through the edge region 110, thus improving the service life of the dimming film 100.

[0059] In some embodiments, such as Figure 1 As shown, the dimming film 100 also includes a central portion, and an edge region 110 is adjacent to the central portion to form the dimming film 100.

[0060] The central portion corresponds to the visible area of ​​the dimming film 100, and the edge area 110 corresponds to the non-visible area of ​​the dimming film 100. The area of ​​the central portion is larger than the area of ​​the edge area 110, and the central portion is used to adjust the transmittance of the dimming film 100 or to adjust the amount of light passing through the dimming film 100. In addition, in some embodiments of this application, the central portion is the color-changing area in the dimming film 100, and the edge area 110 is the non-color-changing area of ​​the dimming film 100.

[0061] like Figures 2 to 9 As shown, in some embodiments of this application, the edge region 110 of the dimming film 100 is provided with a plurality of notches 111, the plurality of notches 111 are spaced apart, the notches 111 penetrate the first conductive layer 130, the dimming layer 140 and the second conductive layer 150, and the notches 111 also penetrate at least one of the first base layer 120 and the second base layer 160.

[0062] It is understood that in some embodiments, the notch 111 penetrates the first substrate layer 120, the first conductive layer 130, the dimming layer 140, and the second conductive layer 150. In other embodiments, the notch 111 penetrates the second substrate layer 160, the second conductive layer 150, the dimming layer 140, and the first conductive layer 130.

[0063] In this embodiment, the notch 111 penetrates the first substrate layer 120, the first conductive layer 130, the dimming layer 140, the second conductive layer 150, and the second substrate layer 160. The structure of the notch 111 can be specifically set according to the thickness of the edge region 110. By controlling the depth of the notch 111 along the thickness direction of the dimming film 100, the thickness of the edge region 110 can be adjusted, reducing thickness differences and improving the uniformity of the edge region 110 thickness. The width d of the notch satisfies: 4mm ≤ d ≤ 12mm.

[0064] Since the first colloid 200 and the second colloid 300 partially overlap to form an overlapping portion 400, it can be understood that the thickness of the overlapping portion 400 is the sum of the thickness of the first colloid 200 and the thickness of the second colloid 300. In other words, the thickness of the edge region 110 in the overlapping portion 400 is greater than the thickness of other areas of the edge region 110, resulting in a large difference in thickness between the edge region 110 in the overlapping portion 400 and other areas. This makes it easy for the edge of the dimming film to detach or break during the lamination and pressing process.

[0065] Based on this, such as Figures 2 to 9 As shown, in some embodiments of this application, projected along the stacking direction of the dimming film 100, the overlapping portion 400 is located in the notch 111, that is, the overlapping portion 400 can be accommodated in the notch 111. By avoiding placing the overlapping portion 400 in other areas of the edge region 110 and increasing the thickness of other areas of the edge region 110, it is possible to avoid the edge region 110 being locally too thick and increasing the thickness difference between various areas of the edge region 110, thereby ensuring the uniformity of the thickness of each area of ​​the edge region 110. It is understood that the thickness of the dimming film 100 at the notch 111 is less than the thickness of other areas of the dimming film 100. By placing the overlapping portion 400 at the notch 111, the corresponding thickness of the dimming film 100 at the notch 111 is increased, thereby reducing the difference between the corresponding thickness of the dimming film 100 at the notch 111 and the corresponding thickness of other areas, ensuring the uniformity of the thickness of the edge region 110 of the dimming film 100, thereby avoiding delamination or breakage during the lamination and pressing process.

[0066] It should be noted that if the width of the notch 111 is small, a portion of the overlapping portion 400 may be disposed within the notch 111, while another portion of the overlapping portion 400 may extend to the first surface 121 and the second surface 161. This results in a significant thickness difference between the thickness of the edge region 110 adjacent to the notch 111 and the thickness of other areas of the edge region 110, potentially leading to delamination or breakage during the lamination and pressing process. Therefore, as... Figure 9 As shown, in some embodiments of this application, along the side of the dimming film 100, the plurality of notches 111 include a first notch 1111 and a second notch 1112, the width of the first notch 1111 is greater than the width of the second notch 1112, and along the projection of the dimming film 100 in the stacking direction, the overlapping portion 400 is located in the first notch 1111.

[0067] like Figure 9As shown, the width of the first gap 1111 is greater than the width of the second gap 1112, and the projection of the overlap portion 400 along the stacking direction of the light control film 100 is located in the first gap 1111. It can be understood that the overlap portion 400 is arranged in the gap 111 with a larger width, so that the overlap portion 400 can be completely accommodated in the gap 111, so as to avoid the overlap portion 400 being too thick, thereby ensuring the uniformity of the thickness of the edge area 110 of the light control film 100.

[0068] As shown in FIG. 1, the light control film 100 includes a first electrode 151, a second electrode 131, a first gap 111, a second gap 112, and an overlap portion 400. Figure 10 and Figure 11 As shown, in some embodiments of the present application, the width of the gap 111 along the side of the light control film is d, wherein the value range of d is 4mm≤d≤12mm.

[0069] It can be understood that the value range of d can be any one of 4mm≤d≤5mm, 5mm≤d≤6mm, 6mm≤d≤7mm, 7mm≤d≤8mm, 8mm≤d≤9mm, 9mm≤d≤10mm, 10mm≤d≤11mm, 11mm≤d≤12mm, which can be specifically set according to actual conditions.

[0070] It should be noted that when the value of d is too large, the area of the gap 111 of the edge area 110 increases, which reduces the area of the electrode region (the first electrode 151 and the second electrode 131) of the edge area 110, and increases the time for the current to pass through the first conductive layer 130 and the second conductive layer 150 of the edge area 110 to other regions of the light control film 100 when the light control film 100 forms an electrical connection with an external power source through the first electrode 151 and the second electrode 131, thereby reducing the color changing speed of the light control film 100.

[0071] In addition, when the value of the gap 111 is too small, i.e., the distance between the two ends of the gap 111 along the arrangement direction of the first gel 200 and the second gel 300 is reduced, the first conductive layer 130 and the second conductive layer 150 exposed at the two ends of the gap 111 are likely to be in contact during the process of laminating and pressing the light control film 100, which may cause a short circuit of the light control film 100, and when the gap 111 is too small, the overlap portion 400 is difficult to be completely accommodated in the gap 111, which not only increases the thickness of the light control device at the gap 111, but also increases the risk of laminating.

[0072] Therefore, the present application sets the width of the gap 111 between 4mm and 12mm to ensure the stability and quality of the bonding of the overlapping portion 400 at the gap 111, and the overlapping portion 400 can be accommodated in the gap 111, thereby avoiding the increase of the thickness at the gap 111, and effectively controlling the electrode area of the edge area 110 to ensure the color changing speed of the dimming film 100. In addition, it can also avoid the contact between the first conductive layer 130 and the second conductive layer 150 exposed at both ends of the gap 111 during the lamination of the dimming film 100, and the short circuit of the dimming film 100, thereby ensuring the safety and stability of the dimming film 100 during use.

[0073] As shown in Figure 1 In some embodiments of the present application, the edge area 110 of the dimming film 100 is provided with first grooves 112 and second grooves 113 arranged alternately.

[0074] The first grooves 112 penetrate the first substrate layer 120, the first conductive layer 130 and the dimming layer 140, and expose part of the second conductive layer 150, so as to form a first electrode 151 through the exposed part of the second conductive layer 150, and electrically connect the first electrode 151 with an external power supply.

[0075] In addition, the second grooves 113 penetrate the second substrate layer 160, the second conductive layer 150 and the dimming layer 140, and expose part of the first conductive layer 130, so as to form a second electrode 131 through the exposed part of the first conductive layer 130, and electrically connect the second electrode 131 with an external power supply, thereby connecting the first conductive layer 130 and the second conductive layer 150 with the external power supply respectively.

[0076] In the present embodiment, the gap 111 communicates with the first grooves 112 and the second grooves 113. By arranging the first adhesive 200 and the second adhesive 300 in the edge area 110, different areas of the edge area 110 are sealed by the first adhesive 200 and the second adhesive 300 respectively, which not only ensures the sealing quality of different areas of the edge area 110, but also effectively improves the sealing efficiency. By arranging the overlapping portion in the gap 111 to reduce the thickness difference between the areas of the edge area 110, the thickness of the edge area 110 is kept uniform, thereby ensuring the stability and safety of the lamination.

[0077] As shown in Figure 12 and Figure 13As shown, in some embodiments of this application, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161, and / or, the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161. It is understood that in some embodiments, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161 to form a seal on the edge area 110 of the dimming film 100, increasing the difficulty for moisture in the environment to enter the dimming film 100, reducing the probability of moisture contacting the dimming layer 140 in the dimming film 100, reducing the risk of discoloration and failure of the dimming film 100, thereby improving the service life of the dimming device.

[0078] In some embodiments, the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161 to form a sealing effect on the edge area 110 of the dimming film 100 through the second colloid 300. This increases the difficulty for moisture in the environment to enter the dimming film 100, reduces the probability of moisture contacting the dimming layer 140 in the dimming film 100, reduces the risk of discoloration and failure of the dimming film 100, and thus improves the service life of the dimming device.

[0079] In some embodiments, the first colloid 200 at least covers the first surface 121, the first groove 112, and the second surface 161, and the second colloid 300 at least covers the first surface 121, the second groove 113, and the second surface 161. It is understood that by disposing the first colloid 200 at the first groove 112 and the second colloid 300 at the second groove 113, the first colloid 200 can seal the first groove 112, ensuring the sealing quality of the edge area 110 at the first groove 112, and the second colloid 300 can seal the second groove 113, ensuring the sealing quality of the edge area 110 at the second groove 113.

[0080] like Figures 2 to 9 As shown, in some embodiments of this application, the plurality of colloids includes a first colloid 200 and a second colloid 300.

[0081] The first colloid 200 includes a first adhesive layer 210 and a second adhesive layer 220. One end of the first adhesive layer 210 is disposed on the first surface 121, and one end of the second adhesive layer 220 is disposed on the second surface 161. The first adhesive layer 210 and the second adhesive layer 220 cooperate to cover the side surface 170 of the dimming film 100 and then become a single unit and extend in a direction away from the side surface 170.

[0082] The second colloid 300 includes a third adhesive layer 310 and a fourth adhesive layer 320. One end of the third adhesive layer 310 is disposed on the first surface 121, and one end of the fourth adhesive layer 320 is disposed on the second surface 161. The third adhesive layer 310 and the fourth adhesive layer 320 cooperate to cover the side surface 170 of the dimming film 100 and are then integrated and extend in a direction away from the side surface 170.

[0083] Since the first colloid 200 and the second colloid 300 partially overlap at the notch 111 to form an overlapping portion, the first adhesive layer 210 can partially overlap with the second colloid 300 at the notch 111 to form an overlapping portion, and the second adhesive layer 220 can partially overlap with the second colloid 300 at the notch 111 to form an overlapping portion; in addition, the first colloid 200 and the third adhesive layer 310 can partially overlap at the notch 111 to form an overlapping portion, and the first colloid 200 and the fourth adhesive layer 320 can partially overlap at the notch 111 to form an overlapping portion.

[0084] Specifically, such as Figure 2 As shown, in this embodiment, the first adhesive layer 210 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0085] like Figure 3 As shown, in this embodiment, the second adhesive layer 220 and the third adhesive layer 310 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0086] like Figure 4 As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0087] like Figure 5 As shown, in this embodiment, the second adhesive layer 220, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0088] like Figure 6 As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220 and the third adhesive layer 310 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0089] like Figure 7 As shown, in this embodiment, the first adhesive layer 210, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0090] like Figure 8As shown, in this embodiment, the first adhesive layer 210, the second adhesive layer 220, the third adhesive layer 310 and the fourth adhesive layer 320 partially overlap each other at the notch 111 to form an overlapping portion 400.

[0091] like Figure 12 As shown, in this embodiment, the first adhesive layer 210 and the second adhesive layer 220 extend to cover the side surface 170, and the distance from the side of the connection between the first adhesive layer 210 and the second adhesive layer 220 away from the side surface 170 is equal to the thickness of the first adhesive layer 210 or the thickness of the second adhesive layer 220, that is, the first adhesive layer 210 and the second adhesive layer 220 are integrally connected and formed on the side surface 170. In addition, the third adhesive layer 310 and the fourth adhesive layer 320 extend to cover the side surface 170, and the third adhesive layer 310 and the fourth adhesive layer 320 are integrally formed on the peripheral side surface to form a "U"-shaped sealing structure in the edge area 110. This not only seals the edge area 110, but also reduces the width occupied by the "U"-shaped sealing structure in the edge area 110, thereby adapting to edge areas with small sealing widths and ensuring sealing quality. It can be understood that in this embodiment, both the first adhesive 200 and the second adhesive 300 are set as "U"-shaped sealing structures in the edge area.

[0092] like Figure 13 As shown, in some embodiments of this application, the first colloid 200 includes a first adhesive layer 210 and a second adhesive layer 220. One end of the first adhesive layer 210 is disposed on the first surface 121, and one end of the second adhesive layer is disposed on the second surface 161. The first adhesive layer 210 and the second adhesive layer 220 respectively extend to cover the side surface 170, and the distance from the side of the connection between the first adhesive layer 210 and the second adhesive layer 220 away from the side surface 170 to the side surface 170 is greater than the thickness of the first adhesive layer 210 or the thickness of the second adhesive layer 220, that is, the first adhesive layer 210 and the second adhesive layer 220 overlap on the peripheral side surface. Similarly, the third adhesive layer 310 and the fourth adhesive layer 320 extend to cover the side surface 170 and overlap at the side surface 170 to form a "Y"-shaped sealing structure at the edge area 110. This not only improves the sealing quality of the edge area 110 but also prevents liquid or moisture from entering the dimming diaphragm 100 from the connection between the side surface 170 and the first surface 121, or from the connection between the side surface 170 and the second surface 161. This reduces the probability of moisture contacting the dimming material in the dimming diaphragm 100, reduces the risk of discoloration and failure of the dimming material, and thus improves the service life of the dimming diaphragm 100. It is understood that in this embodiment, both the first adhesive 200 and the second adhesive 300 are configured with a "Y"-shaped sealing structure at the edge area.

[0093] In the above embodiment, the first glue 200 and the second glue 300 can be used to set different sealing modes in different areas of the edge area 110. It can be understood that the "Y" shaped sealing structure extends at the side surface 170, which is beneficial for the dispersion of the wrinkles, and can be applied to both the straight edge area and the curved edge area; the "U" shaped sealing structure is bent at the side surface 170, and the bending part is prone to form wrinkles, which can be applied to the straight edge area. By setting different types of sealing structures, the sealing quality and sealing effect of the edge area 110 in each area can be ensured, and the flatness of the edge area sealing can also be improved.

[0094] In some embodiments, the first glue 200 is arranged in the curved edge area of the light control film 100, and the second glue 300 is arranged in the straight edge area of the light control film 100; the first glue layer 210 partially covers the third glue layer 310, and the second glue layer 220 partially covers the fourth glue layer 320.

[0095] In the present embodiment, the first glue 200 in the curved edge area and the second glue 300 in the straight edge area can be set in steps. For example, the second glue 300 in the straight edge area can be arranged along the straight edge area according to the length of the straight edge by using a roll material, and the first glue 200 in the curved edge area can be bonded by using a sheet material consistent with the shape of the curved edge area. It can be understood that when the second glue 300 is set first and then the first glue 200 is set, the first glue 200 in the curved edge area will cover the end part of the second glue 300 in the straight edge area to form a continuous first glue 200 and second glue 300. In addition, the curved edge area of the light control film 100 is usually shorter, and the straight edge area is usually longer. When the first glue 200 in the curved edge area is set later, it is more convenient to use the end part of the second glue 300 for positioning. Especially when the curved edge area is located between two straight edge areas, the two ends of the first glue 200 on the curved edge area can be positioned by the end parts of the two second glues 300 respectively, so as to avoid positioning the first glue 200 at each place on the curved edge area, thereby reducing the difficulty of setting the first glue 200 in the curved edge area and simplifying the production process of the light control film 100.

[0096] The light control device further comprises a first bus bar 500 and a second bus bar 600, the first bus bar 500 is at least partially located in the first groove 112, and the first glue layer 210 and the third glue layer 310 cover the first bus bar 500; the second bus bar 600 is at least partially located in the second groove 113, and the second glue layer 220 and the fourth glue layer 320 cover the second bus bar.

[0097] In the embodiments of the present application, as shown in Figure 12 and Figure 13As shown, the first bus bar 500 is at least partially located in the first groove 112, and the second bus bar 600 is at least partially located in the second groove 113. By arranging the first bus bar 500 and the second bus bar 600, the first electrode 151 in the first groove 112 and the first bus bar 500 are connected, and the second electrode 131 in the second groove 113 and the second bus bar 600 are connected, so that the light control film 100 is powered by the first bus bar 500 and the second bus bar 600, and the transmittance of the light control film 100 is adjusted.

[0098] The first adhesive layer 210 and the third adhesive layer 310 are located on one side of the first surface 121 and cover the first bus bar 500, which fixes the first bus bar 500 and protects the first bus bar 500 from water vapor erosion, thereby affecting the electrical conduction effect of the first bus bar 500. In addition, the second adhesive layer 220 and the fourth adhesive layer 320 are located on one side of the second surface 161 and cover the second bus bar 600, which fixes the second bus bar 600 and protects the second bus bar 600 from water vapor erosion, thereby affecting the electrical conduction effect of the second bus bar 600.

[0099] In some embodiments, an insulating layer (not shown in the figure) is arranged in the gap 111 and between the first bus bar 500 and the second bus bar 600. In this embodiment, the insulating layer is used to isolate the first bus bar 500 and the second bus bar 600 to prevent the first bus bar 500 and the second bus bar 600 from forming a conduction path and causing the light control film 100 to short circuit, thereby improving the reliability of the product.

[0100] In some embodiments, the adhesive is a composite material including at least a substrate layer and a water absorption layer, and the substrate layer and the water absorption layer are stacked.

[0101] In the above embodiments of the present application, the adhesive (including the first adhesive 200 and the second adhesive 300) includes at least a substrate layer and a water absorption layer. The water absorption layer is a polymer water absorption material, which 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). By arranging the water absorption material in the adhesive layer, the effect of the adhesive in preventing water vapor is further improved.

[0102] As shown in the drawings, Figure 14 Some embodiments of the present application provide a light adjusting device, comprising a first substrate layer 700, a first adhesive layer 800 and a light adjusting device according to any one of the embodiments described above, a second adhesive layer 900 and a second substrate layer 1000.

[0103] The light adjusting device further comprises a sealing member 1100, which is arranged between the first substrate layer 700 and the second substrate layer 1000 and surrounds the periphery of the light adjusting device, i.e. one side of the sealing member 1100 facing the first substrate layer 700 is connected to the first substrate layer 700, one side of the sealing member 1100 facing the second substrate layer 1000 is connected to the second substrate layer 1000, and one side of the first adhesive layer 800 and the second adhesive layer 900 facing the sealing member 1100 is connected to the sealing member 1100, so as to form a sealed space by the first substrate layer 700, the sealing member 1100 and the second substrate layer 1000, i.e. the light adjusting device is accommodated in the sealed space.

[0104] Specifically, the first substrate layer 700 and the second substrate layer 1000 are both transparent structures, for example, the first substrate layer 700 and the second substrate layer 1000 can be transparent glass, transparent acrylic plate or transparent PVC plate, etc. Preferably, the first substrate layer 700 and the second substrate layer 1000 are glass, and the light adjusting device is formed by sandwiching the light adjusting device between the first substrate layer 700 and the second substrate layer 1000, so as to avoid the light adjusting film 100 from contacting with external moisture and oxygen, thereby improving the service life of the light adjusting film 100 and the light adjusting device.

[0105] The material of the sealing member 1100 includes conventional glue with water and oxygen blocking effect in the art, for example, one of pressure sensitive glue, hot melt glue, UV light curing glue, heat curing glue or UV and heat double curing glue. It can be understood that in some cases, the sealing member 1100 can adopt the same material as the first adhesive layer 800 and the second adhesive layer 900.

[0106] In addition, the surface of the first substrate layer 700 and / or the second substrate layer 1000 corresponding to the edge area 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 700 and / or the second substrate layer 1000; the shielding layer can be made of metal, black ink or other shielding materials. In order to avoid the user directly seeing the edge area 110 of the light adjusting device through the transparent first substrate layer 700 and / or the second substrate layer 1000, the appearance of the entire device is more beautiful. Therefore, the shielding layer is arranged at the edge of the first substrate layer 700 and / or the second substrate layer 1000, and the shielding layer shields the bus bar and the glue of the light adjusting device, thereby improving the appearance of the light adjusting device.

[0107] The light adjusting device or light adjusting apparatus in some embodiments of the present application is suitable for different light adjusting products, and it can be understood that the light adjusting products have the functions and beneficial effects of the light adjusting device or light adjusting apparatus in any one of the above embodiments, which will not be described one by one here.

The vehicle includes a car, a train, an airplane, a ship, etc. The electronic device includes a mobile phone, a computer, a tablet, a smart wearable device, etc. The glasses include ordinary glasses, AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, sunglasses, or ski goggles, etc.
