Description

TECHNICAL FIELD

[0001] The present application relates to the structure of electrochromic anti-glare mirror. BACKGROUND

[0002] All-inorganic electrochromic devices are widely used in anti-glare rearview mirror (inside and outside mirrors of car), solar sunshades, solar anti-glare glasses, anti-glare ski goggles, etc. due to the reversible reaction of transparent and colored by low voltage regulation to achieve different transmittance changes, and the comfortable function of anti-glare after color changing.

[0003] Some electrochromic devices use hollow cavity filled with argon gas to protect the device life. When the hollow cavity is damaged, the water vapor in the air will corrode the device and make the device fail. Some electrochromic devices are sandwiched electrochromic devices, which are packaged by sandwiching a glass sheet between two glass sheets. Although this structure is more stable and reliable than the hollow structure, it still has the problem of not being thin enough and being easily damaged due to insufficient sealing.

Also, the

[0032] The structure of the all-inorganic electrochromic anti-glare mirror in Embodiment 1 of the present application is shown in FIG. 1, and the fabrication process thereof is shown in FIG. 2. Figure 1 Figure 2

[0033] Referring to FIG. 1, the all-inorganic electrochromic anti-glare mirror in Embodiment 1 of the present application includes a substrate 10, a first electrode layer 20, an electrochromic layer 30, a second electrode layer 40, and a protective layer 50. Figure 1 ​​The structure of the all-inorganic electrochromic anti-glare mirror in Embodiment 1 of this application includes a light-transmitting substrate 100, an all-inorganic electrochromic unit 200 formed on the light-transmitting substrate 100, a water vapor absorbing membrane 301 disposed on the radially outer side of the all-inorganic electrochromic unit 200, a first high-reflectivity layer 401 deposited on the electrochromic unit and the water vapor absorbing membrane 301, a first sealing portion 3021 of an organic sealing layer 302 formed on the outer side of the water vapor absorbing membrane 301, and a second sealing portion 3022 of the organic sealing layer 302 formed on the outer side of the first high-reflectivity layer 401. The first sealing portion 3021 and the second sealing portion 3022 are integrally connected to form the organic sealing layer 302.

[0034] The light-transmitting substrate 100 can be a completely transparent material, such as a glass substrate (e.g., ordinary glass, tempered glass) or a polymer substrate, with a thickness of approximately 0.7 mm to approximately 6 mm. Substrate materials with varying transparency can also be used depending on the specific requirements.

[0035] The water-absorbing vapor barrier 301 is formed by coating a mixed resin adhesive around the all-inorganic electrochromic unit 200 and then thermosetting it. The mixed resin adhesive is formed by thoroughly mixing SGP ionomer interlayer powder and a water-absorbing resin formed by 4A molecular sieve and polyurethane, followed by mixing with anhydrous thermosetting epoxy resin.

[0036] like Figure 5 As shown, the water vapor-absorbing diaphragm 301 is preferably formed using the following steps: Step S01, the SGP membrane is crushed to form SGP powder; Step S02, the SGP powder is thoroughly mixed with a water-absorbing resin formed from 4A molecular sieve and polyurethane, and the entire process can be carried out in a vacuum mixing tank filled with argon (Ar); Step S03, anhydrous thermosetting epoxy resin is added to the mixed powder and thoroughly stirred to form a mixed resin adhesive; Step S04, the mixed resin adhesive is coated and then thermosetting to form the water vapor-absorbing diaphragm 301. This water vapor-absorbing diaphragm 301 can both absorb water vapor and ensure the stability of the electrochromic unit 200.

[0037] The material of the first high reflectivity layer 401 is selected from one or more of chromium (Cr), silver (Ag), aluminum (Al), zirconium (Zr), and tungsten (W). Taking silver (Ag) and chromium (Cr) as an example, the high reflectivity layer can be a composite layer of silver and chromium, for example, the bottom layer is a deposited silver layer and the top layer is a sputtered deposited chromium layer. The high reflectivity layer can also be a single layer, for example, it can be a single layer of chromium.

[0038] Although the organic sealing layer 302 is described as being divided into a first sealing layer part 3021 and a second sealing layer part 3022 for the sake of convenience of description, it should be understood that the two are integrated to form the organic sealing layer 302 and have the same material, for example, a resin material, in particular, an epoxy resin, in particular, selected from optically transparent epoxy resin glue, organic anhydrous photo oil, etc. The organic sealing layer 302 can be formed by evaporation, spraying, spin coating, inkjet printing, printing, etc.

[0039] The structure of the all-inorganic electrochromic unit 200 in the anti-glare mirror in Embodiment 1 is shown in Figure 1

[0040] The materials of the first conductive layer 201 and the second conductive layer 205 are selected from one or more of indium tin oxide (ITO), aluminum zinc oxide (AZO), boron zinc oxide (BZO), gallium zinc oxide (GZO), indium gallium zinc oxide (IGZO), and fluorine-doped tin oxide (FTO).

[0041] The first electrochromic layer 202 and the second electrochromic layer 204 have an ionic complementary relationship and can realize linked color change, for example, the first electrochromic layer 202 has reduced light transmittance when it obtains ions, and the second electrochromic layer 204 has reduced light transmittance when it loses ions. For example, the material of the first electrochromic layer 202 is selected from one or more of tungsten oxide (WOx), molybdenum oxide (MoOx), niobium oxide (NbOx), titanium oxide (TiOx), and tantalum oxide (TaOx). The material of the second electrochromic layer 204 is selected from one or more of nickel oxide (NiOx), iridium oxide (IrOx), manganese oxide (MnOx), cobalt oxide (CoOx), tungsten nickel oxide (WNizOx), tungsten iridium oxide (WIrzOx), tungsten manganese oxide (WMnzOx), and tungsten cobalt oxide (WCozOx).

[0042] The material of the ion-conducting layer (IC) 203 is selected from one or a mixture of the following materials: lithium silicon oxide (LiSizOx), lithium tantalum oxide (LiTazOxNy), lithium niobium oxide (LiNbzOx), lithium cobalt oxide (LiCozOx), lithium aluminum oxide (LiAlzOx), lithium phosphorus oxynitride (LiPzOx), and lithium boron oxide (LiBzOx).

[0043] ​The inorganic sealing layer 206 is made of one or more of the following materials or a mixture thereof: silicon oxide (SiOx), niobium oxide (NbOx), aluminum oxide (AlOx), boron oxide (BOx) and silicon nitride (SiON) and aluminum nitride (AlON) in the form of an alternating inorganic sealing film layer of not less than four layers.

[0044] This application utilizes an encapsulation structure formed by combining an inorganic and an organic sealing layer to reduce the impact of a single encapsulation glass layer on transmittance. This increases the transmittance variation range of the electrochromic device, allowing for ultra-thin device structures and rapid encapsulation of arbitrary shapes and structures. The inorganic sealing layer 206 provides high-density moisture barrier but has pores, while the organic sealing layer 302 exhibits strong leveling properties, adhesion, and high strength. The moisture-absorbing membrane 301 maintains the dryness of the inorganic sealing layer and provides moisture barrier functionality.

[0045] As described above, the material of the water-absorbing vapor barrier 301 can be formed by applying a mixed resin adhesive, which is made by thoroughly mixing SGP ionomer interlayer powder and a water-absorbing resin formed by 4A molecular sieve and polyurethane, and then mixing it with an anhydrous thermosetting resin, to the perimeter and then thermosetting it. Application can be achieved using processes such as dispensing, inkjet printing, printing, or spraying.

[0046] The photosensitive element is a thin-film surface-mount photosensitive element, 501A or 501B. The photosensitive element is integrated through an IC driver module. This integrated photosensitive element allows for effective active adaptive adjustment; it automatically captures light intensity and adaptively adjusts to ensure eye comfort and improve safety. Specifically, the photosensitive element can be a photoelectric conversion sensor based on the semiconductor photoelectric effect, generating a light intensity signal by capturing light intensity. The controller receives this signal and controls the tinting depth of the electrochromic layer and the entire anti-glare rearview mirror based on this signal. The basic control principle is as follows: when strong light shines on the rearview mirror surface, the photosensitive element captures the light intensity signal. If the controller determines that the light intensity from the front of the vehicle is greater than the light intensity from the rear, it disables the anti-glare function, and the mirror color remains normal. Conversely, if the controller determines that the light intensity from the front of the vehicle is less than the light intensity from the rear, it activates the anti-glare function, and the mirror color darkens. The photosensitive element can be directly sealed inside a moisture barrier layer.

[0047] like Figure 2 As shown, the manufacturing process of the all-inorganic electrochromic anti-glare mirror in Embodiment 1 is as follows:

[0048] Step S1, a first conductive layer (CL1) 201 is formed on the light-transmitting substrate 100, which is also called a first transparent electrode layer; the forming step includes depositing a material layer selected from one or more of indium tin oxide (ITO), aluminum zinc oxide (AZO), boron zinc oxide (BZO), gallium zinc oxide (GZO), indium gallium zinc oxide (IGZO), fluorine-doped tin oxide (FTO).

[0049] Step S2, a first electrochromic layer (EC1) 202 is formed on the first conductive layer 201, which is also called a bottom electrochromic layer.

The material is selected from the following materials or their mixtures: lithium silicon oxide (LiSizOx), lithium tantalum oxide (LiTazOx), lithium niobium oxide (LiNbzOx), lithium cobalt oxide (LiCozOx), lithium aluminum oxide (LiAlzOx), lithium phosphorus oxide (LiPzOx), lithium boron oxide (LiBzOx).

[0051] Step S4, a second electrochromic layer 204 is formed on the ion-conducting layer 203. The forming step includes depositing a second electrochromic layer 204 film on the ion-conducting layer 203, with a film thickness of 150-650 nm, and the material is selected from nickel oxide (NiOx), iridium oxide (IrOx), manganese oxide (MnOx), cobalt oxide (CoOx), tungsten nickel oxide (WNizOx), tungsten iridium oxide (WIrzOx), tungsten manganese oxide (WMnzOx), tungsten cobalt oxide (WCozOx).

[0052] Step S5, a second conductive layer (CL2) 205 is formed on the second electrochromic layer 204, which is also called a second transparent electrode layer. The forming step of the second conductive layer includes depositing a layered material selected from one or more of indium tin oxide (ITO), aluminum zinc oxide (AZO), boron zinc oxide (BZO), gallium zinc oxide (GZO), indium gallium zinc oxide (IGZO), fluorine-doped tin oxide (FTO) on the second electrochromic layer EC2.

[0053] Step S6, forming an inorganic sealing layer 206 on the second conductive layer 205, the material of the inorganic sealing layer 206 is selected from one or more of silicon oxide (SiOx), niobium oxide (NbOx), aluminum oxide (AlOx), boron oxide (BOx), and silicon nitride (SiON), aluminum nitride (AlON) is alternately formed, and an inorganic sealing film layer with no less than four layers of alternation is formed.

[0054] Step S7: forming a water vapor absorbing membrane 301 on the periphery of the electrochromic unit 200, the thickness of the water vapor absorbing membrane is 800 nm to 2.0 um; the processing technology can be to use dispensing, inkjet printing, printing, spraying and other processes to fully mix SGP plasma polymer interlayer powder and water-absorbing resin formed by 4A molecular sieve and polyurethane, and then mix with anhydrous thermosetting resin to form a mixed resin glue, which is coated on the periphery of the electrochromic unit and heat cured to form a water vapor absorbing membrane.

[0055] In addition to the above-mentioned SGP, PVE and PU can also be used as the polymer material of the water vapor absorbing membrane. In addition, in the water vapor absorbing membrane, the total proportion of one or more of SGP, PVE and PU is 15% to 50%, the total proportion of the water-absorbing resin formed by 4A molecular sieve and polyurethane is 20% to 35%, and the remaining 15% to 70% of anhydrous thermosetting transparent epoxy resin glue is added, and the mixed resin glue formed after being fully mixed.

[0056] Step S8: forming a first high reflection layer 401 above the electrochromic unit 200 and the water vapor absorbing membrane 301, the material of the first high reflection layer 401 is selected from one or more of chromium (Cr), silver (Ag), aluminum (Al), zirconium (Zr), and tungsten (W). Taking silver (Ag) and chromium (Cr) as an example, the high reflection layer can be a composite layer of silver and chromium, for example, the bottom layer is a sputtered silver layer, and the upper layer is a sputtered chromium layer. The first high reflection layer can be a single layer, for example, it can also be a single layer of chromium.

[0057] Step S9: forming an organic sealing layer 302: the thickness of the organic sealing layer is 500 um to 3000 um, and the material is selected from optically transparent epoxy resin glue, organic anhydrous photo oil and the like. Evaporation, spraying, spin coating, inkjet printing, printing and the like can be used to form an organic sealing layer 302 on the surface of the first high reflection layer 401 and the water vapor absorbing membrane 301.

[0058] In the embodiment of the present application, the step S81 of adding a photosensitive element is also included: in this step, the photosensitive element 501A, 501B is attached to the surface of the first high reflection layer 401 by patching process.

[0059] The structure of the electrochromic anti-glare mirror in Embodiment 2 of the present application is as follows: Figure 3As shown, it also includes a light-transmitting substrate 100, a full-inorganic electrochromic unit 200 formed on the light-transmitting substrate 100, a water-vapor-absorbing membrane 301 arranged on the outside of the full-inorganic electrochromic unit 200 in the radial direction, a first high-reflection layer 401 deposited on the electrochromic unit and the water-vapor-absorbing membrane 301, a first sealing part 3021 of an organic sealing layer 302 formed on the outside of the water-vapor-absorbing membrane 301, a second sealing part 3022 of the organic sealing layer 302 formed on the outside of the first high-reflection layer 401, and the first sealing part 3021 and the second sealing part 3022 being integrated to form the organic sealing layer 302.

[0060] Unlike in Example 1, the outside of the bottom of the full-inorganic electrochromic unit 200 in the radial direction in Example 2 is provided with a second high-reflection layer 402. The water-vapor-absorbing membrane 301 is arranged on the outside of the full-inorganic electrochromic unit 200 in the radial direction between the first high-reflection layer 401 and the second high-reflection layer 402; and the first sealing part 3021 of the organic sealing layer is formed on the outside of the first high-reflection layer 401, the second high-reflection layer 401, and the water-vapor-absorbing membrane 301 therebetween.

[0061] The first conductive layer 201 of the full-inorganic electrochromic unit 200 closest to the light-transmitting substrate 100 also has a two-part structure, namely a first conductive layer first part 2011 located inside the radial direction of the second high-reflection layer 402 and a first conductive layer second part 2012 located above the second high-reflection layer 402, and the first conductive layer first part 2011 and the first conductive layer second part 2012 have a size difference in the radial direction due to the presence of the second high-reflection layer.

[0062] The manufacturing steps of the full-inorganic electrochromic anti-glare mirror in Example 2 are similar to those in Example 1, as shown in Figure 4 The difference lies in the following steps:

[0063] In step S1, a first part 2011 of a first conductive layer (CL1) 201 is formed on a glass substrate 100, a second high-reflection layer 402 is formed on the outside of the first part 2011 of the first conductive layer in the radial direction, and a second part 2012 of the first conductive layer is formed on the first part 2011 of the first conductive layer and the second high-reflection layer 402.

[0064] The radial position of the electrode of the full-inorganic electrochromic unit 200 can be arranged above the second high-reflection layer 402, so that the electrode cannot be seen from below the light-transmitting substrate.

[0065] In the electrochromic anti-glare mirror in some embodiments of the present application, the first high reflection layer and the second high reflection layer can be made into various forms such as semi-transmission and full reflection according to the use requirements.

[0066] Through the sealing process of the organic-inorganic multilayer, the substrate of any structure and shape can be processed, and the advantages of ultra-thin, high-transmission, environmental stability and the like can be realized.

[0067] The electrochromic anti-glare mirror in some embodiments of the present application simplifies the current electrochromic anti-glare rearview mirror sandwich structure, and uses the perfect combination of the single-substrate piece anti-glare all-inorganic process and the organic / inorganic packaging process. The advantages of arbitrary shape and large-area uniformity, ultra-wide temperature suitability can be realized, and the matching degree of the double-substrate piece and the unstable process difficulty of the electrochromic unit (organic color-changing gel) in the middle do not need to be considered.

[0068] Unlike the organic anti-glare rearview mirror, the electrochromic anti-glare mirror in some embodiments of the present application can realize the use condition of ultra-low temperature -48℃~150 degrees through the combination of the all-inorganic structure of the electrochromic unit and the organic / inorganic flexible packaging technology. All film layers are prepared on a single-substrate piece, low cost, high yield, and multiple forms; and can have a wide range of complex applications. It is more conducive to the preparation of flexible, single-curved, ultra-thin anti-glare rearview mirrors, anti-glare sunshade transparent plates, and anti-glare sunglasses, and can be widely applied to 3C products, intelligent anti-glare helmets, anti-glare rearview mirrors inside and outside the vehicle, anti-glare sunshades, anti-glare ski goggles, anti-glare sunglasses, and anti-glare lenses.

[0069] The electrochromic anti-glare mirror in some embodiments of the present application can greatly block the invasion of water vapor by setting a water vapor absorption membrane around the electrochromic unit, so that the service life of the device is greatly improved, and the weather resistance is better. Through the full coverage of the inorganic-organic multilayer sealing layer, the device can adapt to various harsh environments, perfectly realize ultra-thin and flexible rapid packaging, and greatly improve the application range of the product and the transmittance of the initial transparent state of the electrochromic unit.

[0070] The water vapor absorption membrane in the electrochromic anti-glare mirror in some embodiments of the present application is formed by fully mixing polymer powder and water absorption type resin formed by 4A molecular sieve and polyurethane, then mixing with anhydrous resin glue powder to form a mixed resin glue, and coating the mixed resin glue around the prime number electrochromic unit and performing heat curing.

[0071] In some embodiments, the water-vapor absorbing diaphragm is preferably formed by the following steps: crushing the SGP film to form a powder; thoroughly mixing the powder with a water-vapor absorbing resin formed by 4A molecular sieve and polyurethane, the mixing being performed in a vacuum mixing tank filled with argon (Ar); adding anhydrous thermosetting resin to the mixed powder and thoroughly stirring to form a mixed resin glue; coating the mixed resin glue and performing heat curing to form the water-vapor absorbing diaphragm. The water-vapor absorbing diaphragm can absorb water vapor and ensure the stability of the electrochromic device.

[0072] The water-vapor absorbing diaphragm is formed with an organic sealing layer on the outer side in the radial direction, which can be a sealing layer of resin material and has a water-vapor isolation function, in which the internal water vapor is absorbed and eliminated by the water-vapor absorbing diaphragm.

[0073] The electrochromic anti-glare mirror in some embodiments of the present application can be well actively and adaptively adjusted by integrating a photosensitive element; the intensity of light is automatically captured for active adaptive adjustment, ensuring the comfort and safety of the glasses. The photosensitive element can be a photoelectric conversion sensor based on semiconductor photoelectric effect, which generates a light intensity signal by capturing light intensity, and a controller receives and controls the coloring depth of the electrochromic layer and the entire anti-glare rearview mirror based on the light intensity signal. The basic control principle is that when strong light irradiates the surface of the rearview mirror, the photosensitive element will capture the light intensity signal, and the controller will determine that the headlight intensity is greater than the rear light intensity, and then the controller will not start the anti-glare function, and the mirror color remains normal. Conversely, when the controller determines that the headlight intensity is less than the rear light intensity, the anti-glare function is started, and the mirror color becomes darker. The photosensitive element can be attached to the first high-reflective layer and sealed in the organic sealing layer.

[0074] In the electrochromic anti-glare mirror in some embodiments of the present application, electronic display products such as streaming media, OLED screens, and HUDs can also be integrated in the organic sealing layer, especially the second sealing part of the organic sealing layer, to provide additional functions.

[0075] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
