Description

TECHNICAL FIELD

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

[0002] The electrochromic phenomenon refers to a reversible color change of an electrochromic material under the action of an applied electric field. The essence is that the electrochromic material undergoes an oxidation-reduction reaction under the action of an applied electric field and current, resulting in a change in the structure of the electrochromic material, and thus a change in the absorption spectrum and optical properties (such as absorbance, transmittance, and reflectance), which is manifested in the reversible change in color and transparency.

[0003] Since the electrochromic material needs to be powered to achieve color change, a lead needs to be provided to connect the electrochromic device to an external power source. When the lead is provided, the conductive layer in the electrochromic device needs to be exposed.

[0004] As shown in FIG. 1, a step structure is provided at the edge of the functional area of the electrochromic device to expose the conductive layer. However, when the lead is connected to the conductive layer, a certain force is applied to the step structure, causing the film layers at the position of the step structure to separate from each other (i.e., film layer separation occurs), which in turn causes the corresponding position of the electrochromic device to fail and be unable to be used normally. With the extension of the use time, the failure area also increases continuously, affecting the normal use of the electrochromic device. Figure 1 SUMMARY

[0005] The present application provides an electrochromic device and apparatus to prevent film layer separation in the functional area.

[0006] The present application provides:

[0007] An electrochromic device, comprising a first substrate, an electrochromic film, and a second substrate which are sequentially stacked;

[0008] The electrochromic film includes a functional area, and the electrochromic device further includes a first sealing member and a lead-out structure group, the first sealing member is arranged around the functional area, and the first sealing member is connected between the first substrate and the second substrate.

[0009] The electrochromic film includes at least one conductive layer, and at least one of the conductive layers is provided through the first sealing member and protrudes from the side of the first sealing member away from the functional area to form at least one mounting portion.

[0013] In some possible embodiments, the mounting portion is bent towards a side away from the electrochromic device, and is fixed on the first substrate and / or the second substrate.

[0014] In some possible embodiments, the electrochromic film is arranged through the first sealing member, and protrudes from a side of the first sealing member away from the functional area to form at least one protruding structure.

[0016] In some possible embodiments, a groove is formed in the at least one protruding structure, and the groove is in communication with the mounting portion, and the lead-out structure group is connected to the mounting portion through the groove.

[0017] In some possible embodiments, the electrochromic device further comprises a second sealing member, which is arranged at least in the groove.

[0018] In some possible embodiments, the at least one protruding structure is arranged to be wrapped by the second sealing member.

[0019] In some possible embodiments, the electrochromic device further comprises a third sealing member, which is arranged at least in the circumferential direction of the at least one protruding structure.

[0020] In some possible embodiments, the third sealing member is arranged in the circumferential direction of the electrochromic film.

[0021] In some possible embodiments, the electrochromic film comprises two conductive layers, the electrochromic device comprises one mounting portion, the mounting portion comprises a first sub-mounting portion and a second sub-mounting portion which are insulated from each other, and the first sub-mounting portion and the second sub-mounting portion are formed in the same conductive layer.

[0022] The first sub-mounting portion is in conduction with another conductive layer, and the second sub-mounting portion is in conduction with the conductive layer in which the second sub-mounting portion is arranged.

[0023] In addition, the present application also provides an electrochromic device comprising the electrochromic device provided by the present application.

[0024] The application provides an electrochromic device and apparatus. The electrochromic device comprises a first sealing member, a lead-out structure group, and a first substrate, an electrochromic film and a second substrate which are sequentially stacked.

The lead-out structure group is connected to the at least one mounting portion.

[0025] In the application, the connection position of the lead-out structure group and the conductive layer is arranged on the side of the first sealing member away from the functional area. On one hand, when the lead-out structure group and the mounting portion are connected, the film layer separation problem occurs on the side of the first sealing member away from the functional area, that is, the film layer separation problem does not occur in the functional area, so that the normal use of the functional area can be ensured. On the other hand, the first sealing member can also block the film layer separation problem, reduce the probability that the film layer separation problem extends from the mounting portion position to the functional area, ensure the use of the functional area, and accordingly, the service life of the electrochromic device can be prolonged.

[0053] Embodiment one

[0054] In the embodiment, an electrochromic device is provided, which can reduce the probability of film separation in the functional area 201, thereby prolonging the service life of the electrochromic device.

[0055] As shown in Figures 2 to 4 The electrochromic device includes a first substrate 11, an electrochromic film 20 and a second substrate 12 which are sequentially stacked, that is, the electrochromic film 20 is sandwiched between the two substrates, so that the two substrates can also protect the electrochromic film 20.

[0056] In the embodiment, at least one of the first substrate 11 and the second substrate 12 is a transparent substrate, so that light can pass through to facilitate the display of the optical property change of the electrochromic device. For example, in some embodiments, the first substrate 11 can be a transparent substrate.

[0057] In some embodiments, the transparent substrate can be made of any one or more of polyethylene terephthalate (PET), cyclic olefin copolymer or cellulose triacetate. For example, the transparent substrate can be made of PET and cyclic olefin copolymer, or made of cyclic olefin copolymer and cellulose triacetate, or made of PET and cellulose triacetate, or made of PET, cyclic olefin copolymer and cellulose triacetate.

[0058] In other embodiments, the transparent substrate can also be made of glass, metal and the like.

[0059] As shown in Figures 2 to 4 The electrochromic film 20 includes a functional region 201. It can be understood that the functional region 201 can modulate the light passing through it, specifically in terms of absorption, transmission, reflectance, etc.

[0060] The electrochromic device further includes a first sealing member 40, which is arranged around the periphery of the functional region 201. In addition, the first sealing member 40 is sandwiched between the first substrate 11 and the second substrate 12, and is connected to the first substrate 11 and the second substrate 12. Thus, the first sealing member 40 can provide the electrochromic device with a corresponding water vapor isolation effect to prevent water vapor from entering the functional region 201 and affecting the modulation of light.

[0061] In some embodiments, the first sealing member 40 can be made of a water and oxygen isolation adhesive, such as any one of pressure-sensitive adhesive, hot melt adhesive, ultraviolet curing adhesive, heat curing adhesive, or ultraviolet and heat dual curing adhesive.

[0062] As shown in Figures 2 to 4 The electrochromic film 20 includes two conductive layers 21, i.e. a first conductive layer 211 and a second conductive layer 212, which are arranged in a spaced manner. It can be understood that the first conductive layer 211 and the second conductive layer 212 are insulated to avoid short circuiting and other problems.

[0063] Of course, in other embodiments, the electrochromic film 20 can also include one, three, four, etc. conductive layers 21.

[0064] In some embodiments, at least one of the two conductive layers 21 is a transparent conductive layer to exhibit the optical property change of the electrochromic device. For example, in some embodiments, the first conductive layer 211 can be a transparent conductive layer. It can be understood that when the electrochromic device is transparent on one side, the conductive layer 21 on the corresponding side and the substrate can be simultaneously selected as transparent structures.

[0065] In embodiments, the transparent conductive layer can be made of one or more of indium-tin oxide (ITO), aluminum zinc oxide (AZO), fluorine doped tin oxide (FTO), silver nanowire, graphene, carbon nanotube, metal mesh, or silver nanoparticles.

[0066] Further, at least one of the first conductive layer 211 and the second conductive layer 212 is arranged through the first sealing member 40 and protrudes from a side of the first sealing member 40 away from the functional area 201 to form at least one mounting portion 210, i.e., the mounting portion 210 is located at the side of the first sealing member 40 away from the functional area 201. Correspondingly, the mounting portion 210 can be exposed to the outside.

[0067] As shown in the drawings, Figure 3 The electrochromic device further includes a lead-out structure group 30, which can be connected to the at least one mounting portion 210 to realize the connection of the lead-out structure group 30 with the first conductive layer 211 and the second conductive layer 212. It can be understood that the lead-out structure group 30 can be used as a lead-out electrode of the electrochromic device to realize the electrical connection of the electrochromic device with a power supply and other electrical elements. Correspondingly, the lead-out structure group 30 can include a first lead-out structure 31 and a second lead-out structure 32, which can be used as a positive lead-out electrode and a negative lead-out electrode of the electrochromic device, respectively. In some embodiments, the lead-out structure group 30 can be a wire or a conductive sheet.

[0068] During the processing of the electrochromic device, the lead-out structure group 30 is usually connected to the first conductive layer 211 and / or the second conductive layer 212 by pressing, welding or other methods. During this operation, stress will be applied to the corresponding conductive layer 21, which is easy to cause the separation of the film layers of the electrochromic device, thereby causing the failure of the area of the electrochromic device where the film layers are separated, and the electrochromic device cannot modulate light.

[0069] In this application, the mounting portion 210 for connecting the lead-out structure group 30 is arranged at the side of the first sealing member 40 away from the functional area 201, i.e., the mounting portion 210 is isolated from the functional area 201 to avoid the separation of the film layers in the functional area 201, so as to ensure the normal use of the functional area 201. In addition, since the first sealing member 40 is located between the mounting portion 210 and the functional area 201, the separation of the film layers at the position of the mounting portion 210 can be blocked by the first sealing member 40, so as to avoid the spread of the separation of the film layers to the functional area 201 with the extension of the use time, thereby ensuring the normal use of the functional area 201. Correspondingly, the service life of the electrochromic device can also be extended.

[0070] Embodiment Two

[0071] In the embodiment, an electrochromic device is provided. It can be understood that the embodiment can be a further improvement based on the first embodiment.

[0072] As shown in the drawings, Figures 3 to 5As shown, the electrochromic film 20 also includes an electrochromic layer 22 and two substrates 23, namely a first substrate 231 and a second substrate 232. A first conductive layer 211 and a second conductive layer 212 are disposed on opposite sides of the electrochromic layer 22 to apply a corresponding voltage to the electrochromic layer 22. The first substrate 231 is disposed between the first conductive layer 211 and the first substrate 11, and the second substrate 232 is disposed between the second conductive layer 212 and the second substrate 12.

[0073] Understandably, the substrate 23 can serve as a carrier for the corresponding conductive layer 21, providing a platform and support for the corresponding conductive layer 21. Accordingly, the substrate 23 can be extended from the corresponding side of the mounting portion 210, that is, the substrate 23 at the corresponding position and the conductive layer 21 are together inserted into the first sealing member 40, and protrude from the side of the first sealing member 40 away from the functional area 201.

[0074] In some embodiments, the material of the substrate 23 may be selected from one or more combinations of PET, cyclic olefin copolymers, or cellulose triacetate. For example, a combination of PET and cyclic olefin copolymers, a combination of cyclic olefin copolymers and cellulose triacetate, a combination of PET and cellulose triacetate, or a combination of PET, cyclic olefin copolymers, and cellulose triacetate.

[0075] In this embodiment, the electrochromic layer 22 may be a gel-state electrochromic structure, or a single-layer or multi-layer all-solid-state electrochromic structure. For example, the electrochromic layer 22 may be made of polymer-dispersed liquid crystal (PDLC) glass, a suspended particle device (SPD), or the like.

[0076] like Figure 5 As shown, in some embodiments, the electrochromic layer 22 may include an electrochromic material layer 221, an electrolyte layer 222, and a counter electrode layer 223 stacked sequentially. The electrochromic material layer 221 may be disposed near the first conductive layer 211, and the counter electrode layer 223 may be disposed near the second conductive layer 212.

[0077] like Figure 4 As shown, in some embodiments, the electrochromic film 20 can be connected to the two substrates by adhesive bonding. Accordingly, an adhesive layer 50 can be formed between the first substrate 11 and the first substrate 231, and an adhesive layer 50 can also be formed between the second substrate 12 and the second substrate 232.

[0078] In some embodiments, the adhesive layer 50 can be made of optically transparent adhesive material, such as Optically Clear Adhesive (OCA), Solid Optically Clear Adhesive (SCA), Surper Safe Glas (SGP), Liquid Optical Clear Adhesive (LOCA), etc.

[0079] As shown in Figure 2 , Figure 3 and Figure 6 , in some embodiments, the electrochromic device comprises two mounting portions, i.e. a first mounting portion 2101 and a second mounting portion 2102. The two lead-out structures are connected to the two mounting portions 210 one by one, specifically, the first lead-out structure 31 is connected to the first mounting portion 2101, and the second lead-out structure 32 is connected to the second mounting portion 2102.

[0080] Correspondingly, the first substrate 231 is arranged in the first sealing member 40 together with the first conductive layer 211, and protrudes away from the side of the first sealing member 40 far from the functional area 201, so as to form the first mounting portion 2101 on the first conductive layer 211. Similarly, the second substrate 232 is arranged in the first sealing member 40 together with the second conductive layer 212, and protrudes away from the side of the first sealing member 40 far from the functional area 201, so as to form the second mounting portion 2102 on the second conductive layer 212.

[0081] In some embodiments, the first mounting portion 2101 and the second mounting portion 2102 can be arranged one by one on the opposite sides of the electrochromic device in the circumferential direction of the electrochromic device.

[0082] In other embodiments, the first mounting portion 2101 and the second mounting portion 2102 can be located on the adjacent two sides of the electrochromic device. Of course, in other embodiments, the first mounting portion 2101 and the second mounting portion 2102 can also be located on the same side of the electrochromic device.

[0083] As shown in Figure 6 , further, the electrochromic device further comprises a fixing assembly 60, which can be used to fix the mounting portion 210. In embodiments, the fixing assembly 60 can comprise a first fixing member 61 and a second fixing member 62, and the two fixing members can be arranged one by one with the two mounting portions 210, specifically, the first fixing member 61 can be used to fix the first mounting portion 2101, and the second fixing member 62 can be used to fix the second mounting portion 2102.

[0084] In embodiments, the two fixing members are arranged in a similar manner, and the first fixing member 61 is taken as an example for detailed description. In some embodiments, the electrochromic device comprises two mounting portions, i.e. a first mounting portion 2101 and a second mounting portion 2102. The two lead-out structures are connected to the two mounting portions 210 one by one, specifically, the first lead-out structure 31 is connected to the first mounting portion 2101, and the second lead-out structure 32 is connected to the second mounting portion 2102.

[0085] As shown in Figure 6 In some embodiments, the first fixing member 61 can be arranged on the side of the first mounting portion 2101 away from the first substrate 231. The first fixing member 61 can be fixedly connected with the first mounting portion 2101. In addition, the first fixing member 61 is also fixedly connected with the side of the first sealing member 40 away from the functional area 201. That is, the first mounting portion 2101 is further fixedly connected with the first sealing member 40 through the first fixing member 61. Thus, the first mounting portion 2101 can be provided with corresponding fixing and supporting effects, so as to avoid the first mounting portion 2101 from shaking at will and improve the stability of the first mounting portion 2101.

[0086] In some embodiments, the first fixing member 61 can also cover the connection between the first lead-out structure 31 and the first mounting portion 2101, so as to reinforce the connection between the first lead-out structure 31 and the first mounting portion 2101 and enhance the connection strength between the first lead-out structure 31 and the first mounting portion 2101.

[0087] In other embodiments, the first fixing member 61 can also extend to the side edge of the side corresponding to the second substrate 12 in the thickness direction of the electrochromic device and be fixedly connected.

[0088] In other embodiments, the first fixing member 61 can also be arranged on the side of the protruding part of the first substrate 231 away from the first mounting portion 2101. It can be understood that the protruding part of the first substrate 231 can refer to the protruding part of the first substrate 231 away from the side of the functional area 201 of the first sealing member 40. Correspondingly, the first fixing member 61 can be connected between the protruding part of the first substrate 231 and the first sealing member 40. Of course, the first fixing member 61 can also extend to the side edge of the side corresponding to the first substrate 11 and be connected.

[0089] In some embodiments, the first fixing member 61 and the second fixing member 62 can be made of structural glue to realize the fixed connection between the corresponding mounting portion 210 and the first sealing member 40.

[0090] Embodiment Three

[0091] In the embodiment, an electrochromic device is provided. The difference between the embodiment and the embodiment two is that:

[0092] As shown in Figure 7As shown, in some embodiments, the first mounting portion 2101 and the protruding portion of the first substrate 231 are bent together towards the direction close to the second substrate 12 and extend to the side of the second substrate 12 away from the first substrate 11. In embodiments, the side of the first mounting portion 2101 away from the first substrate 231 can be fixedly connected to the second substrate 12, for example, the first mounting portion 2101 can be adhered to the second substrate 12 by means of adhesion. In embodiments, the adhesion between the first mounting portion 2101 and the second substrate 12 can be achieved by OCA glue, SCA glue, LOCA glue, etc. Thus, the first mounting portion 2101 can be fixed accordingly to improve the stability of the first mounting portion 2101.

[0093] In some embodiments, the second mounting portion 2102 and the protruding portion of the second substrate 232 can also be bent together towards the direction close to the second substrate 12 and extend to the side of the second substrate 12 away from the first substrate 11. In embodiments, the side of the second substrate 232 away from the second mounting portion 2102 can be fixedly connected to the side of the second substrate 12 away from the first substrate 11, for example, the second mounting portion 2102 and the second substrate 12 can also be adhered by means of adhesion. Thus, the second mounting portion 2102 can be fixed to improve the stability of the second mounting portion 2102.

[0094] In other embodiments, the first mounting portion 2101 and the second mounting portion 2102 can be bent together towards the direction close to the first substrate 11 and fixed to the first substrate 11 to improve the stability of the two mounting portions 210.

[0095] Of course, in other embodiments, one of the mounting portions 210 can be bent towards the direction close to the first substrate 11 and fixed to the first substrate 11. The other mounting portion 210 can be bent towards the direction close to the second substrate 12 and fixed to the second substrate 12.

[0096] It can be understood that, in embodiments, the mounting portion 210 can be bent and fixed to the corresponding substrate directly to improve the stability of the mounting portion 210, and accordingly, the fixing assembly 60 can not be required.

[0097] Embodiment Four

[0098] In embodiments, an electrochromic device is provided, which differs from the embodiment two in that:

[0099] As shown in Figure 8 and Figure 9 In embodiments, the electrochromic film 20 is arranged in the first sealing member 40 and protrudes away from the side of the functional area 201 of the first sealing member 40 to form two protruding structures 202, i.e., the first protruding structure 2021 and the second protruding structure 2022.

[0100] It can be understood that each structural layer in the electrochromic film 20 passes through the first sealing member 40 together to form a corresponding protruding structure 202, that is, the protruding structure 202 includes the first substrate 231, the first conductive layer 211, the electrochromic layer 22, the second conductive layer 212 and the second substrate 232 arranged in sequence.

[0101] In the embodiment, two mounting portions 210 can be arranged in one-to-one correspondence with two protruding structures 202. Specifically, the first mounting portion 2101 is formed in the first protruding structure 2021, and the second mounting portion 2102 is formed in the second protruding structure 2022.

[0102] Correspondingly, the two protruding structures 202 can be arranged on opposite sides or adjacent sides of the electrochromic device in the circumferential direction of the electrochromic device.

It can be understood that the protruding structure 202 can have stronger structural stability than the mounting portion 210 and the corresponding substrate 23. Therefore, arranging the mounting portion 210 on the protruding structure 202 can also increase the stability of the corresponding mounting portion 210, which can replace the arrangement of the fixing assembly 60.
