[0033] The first surface is away from the first adhesive layer 11, and the second surface is connected to the first adhesive layer 11. The optical element layer 12 is arranged between the first adhesive layer 11 and the second adhesive layer 14, and the transition layer 13 is arranged between the first adhesive layer 11 and the second adhesive layer 14.

The second adhesive layer 14 is bonded to the second glass plate 15 and the optical element layer 12, and the second adhesive layer 14 is bonded to the second glass plate 15 and the transition layer 13.

[0034] The thickness of the outer glass plate is 0.7 mm to 4.0 mm, the visible light transmittance of the first glass plate 10 is ≥ 70%, that is, the visible light transmittance of the outer glass plate is greater than or equal to 70%, the outer glass plate is transparent glass, the total iron content of the transparent glass (in terms of Fe2O3) is less than or equal to 0.1%, even less than or equal to 0.05%, further less than or equal to 0.01%, and the visible light transmittance of the transparent glass is 80% to 95%. For example, the outer glass plate can be a transparent glass with a thickness of 2.1 mm and a visible light transmittance of 89%. The thickness of the outer glass plate is preferably 1.6 mm to 3.5 mm.

[0035] The thickness of the inner glass plate is 0.7 mm to 4.0 mm, and the visible light transmittance of the second glass plate 15 is ≥ 70%, that is, the visible light transmittance of the inner glass plate is greater than or equal to 70%.

[0036] The first adhesive layer 11 and the second adhesive layer 14 can both be transparent thermoplastic polymer films or colored thermoplastic polymer films, and the thickness of the first adhesive layer 11 and the second adhesive layer 14 is 0.38mm to 2.28mm. For example, the thickness of the first adhesive layer 11 and the second adhesive layer 14 can be, but not limited to, 0.38mm, or 0.76mm, or 1.14mm, or 1.52mm, or 1.9mm, or 2.28mm, or other values ​​between 0.38mm and 2.28mm. The material of the thermoplastic polymer film can be selected from at least one of polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA) and ionic polymer (SGP). Optionally, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 is ≥80%. When the first adhesive layer 11 and the second adhesive layer 14 are transparent thermoplastic polymers, the visible light transmittance of the transparent thermoplastic polymer is greater than or equal to 80%. For example, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 can be, but not limited to, 80%, 85%, 90%, or 95%. When the first adhesive layer 11 and the second adhesive layer 14 are colored thermoplastic polymer films, the visible light transmittance of the colored thermoplastic polymer film is greater than or equal to 70%. For example, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 can be, but not limited to, 70%, 75%, 80%, 85%, or 90%. The colored thermoplastic polymer film can be selected from gray thermoplastic polymer films, green thermoplastic polymer films, or blue thermoplastic polymer films. Exemplarily, the first adhesive layer 11 and the second adhesive layer 14 can be a single-layer structure or a multi-layer structure. The multi-layer structure can be exemplified by a double-layer structure, a three-layer structure, a four-layer structure, a five-layer structure, etc. The first adhesive layer 11 and the second adhesive layer 14 may also have other functions, such as adding infrared absorbers to provide sun protection or heat insulation functions, or adding ultraviolet absorbers to provide ultraviolet isolation functions, or at least one layer of the multilayer structure has a higher plasticizer content to provide sound insulation functions.

[0037] The optical element layer 12 can also be understood as a dimming layer, which has a dimming function. The optical element layer 12 can be a polymer dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a dye liquid crystal film (LC), etc. Preferably, the optical element layer 12 can be a dye liquid crystal (LC) containing a transparent sealing glue, that is, the optical element layer 12 can be a dye liquid crystal film (LC). The minimum visible light transmittance of the optical element layer 12 is less than or equal to 3%, such as 3%, 2%, 1%, 0.5%, 0%. In addition, the maximum visible light transmittance of the optical element layer 12 is set as needed, such as 10%, 20%, 30%, 50%, 70%, 80%, etc. For example: the visible light transmittance of the optical element layer 12 can be adjusted between 0% and 20%, can also be adjusted between 0.5% and 50%, can also be adjusted between 0% and 70%, etc.

[0038] When the optical element layer 12 is powered on, as the voltage value applied to the optical element layer 12 changes, the optical element layer 12 has different visible light transmittances and different colors to meet the requirements of visible light transmittance and color in multiple scenes. For example, when black border display is required, the optical element layer 12 is in an opaque state (visible light transmittance is less than or equal to 3%, or even 0%) to improve the contrast between the displayed image and the displayed background. When no display is performed, the optical element layer 12 is in a transparent state (visible light transmittance is greater than or equal to 70%) to achieve transparency in a larger area of ​​the laminated glass 1.

[0039] Under different preset conditions, the transition layer 13 has different visible light transmittances and different colors to match the visible light transmittance and color of the optical element layer 12. Specifically, the material of the transition layer 13 is selected from at least one of a photochromic material, a thermochromic material, and a piezochromic material. For example, when the material of the transition layer 13 is selected from a photochromic material, as the amount of radiation received by the transition layer 13 changes, the transition layer 13 has different visible light transmittances and different colors. For another example, when the material of the transition layer 13 is selected from a thermochromic material, as the temperature value of the transition layer 13 changes, the transition layer 13 has different visible light transmittances and different colors. For another example, when the material of the transition layer 13 is selected from a piezochromic material, as the pressure value to which the transition layer 13 is subjected changes, the transition layer 13 has different visible light transmittances and different colors. In addition, the transition layer 13 is also used to fill the area where the optical element layer 12 is smaller than the laminated glass 1.

[0040] The transition layer 13 and the optical element layer 12 are arranged in the same layer, which can also be understood as that the transition layer 13 and the optical element layer 12 are approximately located in the same structural layer. The thickness of the optical element layer 12 is equal to the thickness of the transition layer 13; or, the thickness of the optical element layer 12 is greater than the thickness of the transition layer 13; or, the thickness of the optical element layer 12 is less than the thickness of the transition layer 13, which is not limited in this embodiment. Preferably, the thickness of the optical element layer 12 is equal to the thickness of the transition layer 13.

[0041] In summary, the laminated glass 1 provided in this embodiment, by providing the transition layer 13 with different visible light transmittance and different colors, the transition layer 13 can have a visible light transmittance and color similar to or the same as the optical element layer 12, so as to achieve a natural connection between the transition layer 13 and the optical element layer 12, thereby improving the appearance performance of the laminated glass 1, improving the user experience, and solving the problem of uneven transition between the transition layer 13 and the optical element layer 12. In addition, the black edge printing on the laminated glass 1 in the related art can be omitted, reducing the production cost and the production process.

[0042] In one embodiment, the transition region 131 has a minimum visible light transmittance TL 1min The optical functional area 121 has a minimum visible light transmittance TL 2min ; Wherein, the laminated glass 1 satisfies the following conditions: |TL 1min -TL 2min ∣=X%, 0≤X≤0.5.

[0043] TL 1min with TL 2min The absolute value of the difference is ≤0.5%, and specifically, it can be 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, or 0, etc. Preferably, 0≤X≤0.3. In this embodiment, TL is defined as 1min with TL 2min The absolute value of the difference makes the minimum values ​​of the visible light transmittance of the transition layer 13 and the optical element layer 12 close to or equal to each other, thereby ensuring that the transition layer 13 can have a visible light transmittance close to or the same as that of the optical element layer 12. When the user observes the laminated glass 1 with their eyes, there can be almost no perceptible change between the transition layer 13 and the optical element, thereby better achieving a natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1, and further improving the user experience.

[0044] In the related art, the frame sealant cannot adjust the visible light transmittance. The visible light transmittance of the frame sealant is 80%. The absolute value of the difference between the minimum visible light transmittance of the frame sealant and the optical functional area 121 is 78.2, which is much larger than 0.5, resulting in an abrupt transition between the optical element layer 12 and the frame sealant.

[0045] In one embodiment, the preset condition includes a first preset value and a second preset value. When changing from the first preset value to the second preset value, the transition zone 131 has a visible light transmittance change value △TL1; when changing from the first voltage value to the second voltage value, the optical functional area 121 has a visible light transmittance change value △TL2; wherein the laminated glass 1 satisfies the following conditions: |△TL1-△TL2|=Y%, 0≤Y≤3.

[0046] For example, the first preset value is 0Wh solar radiation, and the second preset value is 7.22Wh solar radiation. When the first preset value changes to the second preset value, the transition area 131 has a visible light transmittance change value △TL1 of 32.1%; the first voltage value is 0V, the second voltage value is 6.6V, and the optical functional area 121 has a visible light transmittance change value △TL2 of 35%. △TL1 and TL 2min The absolute value of the difference △TL2 is 2.9%, which is less than 3%.

[0047] Specifically, the relationship between the solar radiation and the visible light transmittance TL1 of the transition zone 131 is determined by the photochromic material itself. Under a certain radiation amount, the photochromic material has a corresponding TL1 value. Combined with |△TL1-△TL2|=Y%, the △TL2 value can be determined, and then the TL2 value is locked, thereby the voltage value corresponding to the TL2 value. The collected light signal is then converted into an electrical signal through the sensing controller 16, and the electrical signal is matched and set with the voltage value corresponding to the TL2 value, thereby realizing the linkage between the transition layer 13 and the optical element layer 12.

[0048] The absolute value of the difference between △TL1 and △TL2 is ≤3%, and specific examples include 3%, 2.5%, 2%, 1.5%, 1%, 0.5%, or 0, etc. Preferably, 0≤Y≤2, and more preferably, 0≤Y≤1. In this embodiment, the absolute value of the difference between △TL1 and △TL2 is limited to control the optical element layer 12 and the transition layer 13 to have similar or equal visible light transmittance under different environments. No matter how the environment changes, when the user observes the laminated glass 1 with his eyes, the transition layer 13 and the optical element can have almost imperceptible changes, so as to better achieve a natural connection between the transition layer 13 and the optical element layer 12, further improve the appearance performance of the laminated glass 1, and further improve the user experience.

[0049] In the related art, the frame sealant cannot adjust the visible light transmittance. The visible light transmittance of the frame sealant is 80%. When the TL maximum value of the optical element layer 12 is taken, the absolute value of the difference between the visible light transmittance change value of the frame sealant and the optical functional area 121 is 33.2, which is much larger than 3, resulting in an abrupt transition between the optical element layer 12 and the frame sealant.

[0050] In one embodiment, the reflection color of the transition zone 131 to visible light has Lab1 values: L1, a1, b1; the reflection color of the optical functional zone 121 to visible light has Lab2 values: L2, a2, b2; wherein the laminated glass 1 satisfies the following conditions: △E≤3.5.

[0051] The color difference value △E≤3.5, which can be specifically exemplified as 3, or 2.5, or 2, or 1.5, or 1, or 0.5, or 0, etc., preferably, △E≤2. In this embodiment, the color difference value △E is limited to control the optical element layer 12 and the transition layer 13 to have similar or equal colors in different environments. No matter how the environment changes, when the user observes the laminated glass 1 with their eyes, the transition layer 13 and the optical element can have almost imperceptible changes, so as to better achieve a natural connection between the transition layer 13 and the optical element layer 12, further improve the appearance performance of the laminated glass 1, and further improve the user experience.

[0052] In one embodiment, the reflection color of the transition zone 131 to visible light has a transmission Lab1 value: transmission L1, transmission a1, transmission b1; the reflection color of the optical functional zone 121 to visible light has a transmission Lab2 value: transmission L2, transmission a2, transmission b2; wherein the laminated glass 1 satisfies the following conditions: △Transmission E≤3.5.

[0053] The transmittance Lab value refers to the Lab value of the color obtained by the transmittance measurement method. △Transmittance E≤3.5, which can be specifically exemplified as 3, or 2.5, or 2, or 1.5, or 1, or 0.5, or 0, etc. Preferably, △Transmittance E≤2; this embodiment further controls the optical element layer 12 and the transition layer 13 to have similar or equal colors under different environments by limiting the transmittance color difference value △Transmittance E, so as to better achieve the natural connection between the transition layer 13 and the optical element layer 12, further improve the appearance performance of the laminated glass 1, and further improve the user experience.

[0054] In the related art, the color of the frame sealant cannot be adjusted, and the transmittance color difference value Δtransmittance E between the frame sealant and the optical functional area 121 is 46.3, which is much larger than 3.5, resulting in an abrupt color transition between the optical element layer 12 and the frame sealant.

[0055] In one embodiment, the reflection color of the transition zone 131 to visible light has a reflection Lab1 value: reflection L1, reflection a1, reflection b1; the reflection color of the optical functional zone 121 to visible light has a reflection Lab2 value: reflection L2, reflection a2, reflection b2; wherein the laminated glass 1 satisfies the following conditions: △Reflection E≤3.5.

[0056] The reflective Lab value refers to the color of the light reflected from the surface of an object expressed in the Lab color space. △Reflection E≤3.5, which can be specifically exemplified as 3, or 2.5, or 2, or 1.5, or 1, or 0.5, or 0, etc. Preferably, △Reflection E≤2; This embodiment further controls the optical element layer 12 and the transition layer 13 to have similar or equal colors under different environments by limiting the reflective color difference value △Reflection E, so as to better achieve the natural connection between the transition layer 13 and the optical element layer 12, further improve the appearance performance of the laminated glass 1, and further improve the user experience.

[0057] In the related art, the color of the frame sealant cannot be adjusted, and the reflection color difference value △ reflection E between the frame sealant and the optical functional area 121 is 46.3, which is much larger than 3.5, resulting in an abrupt color transition between the optical element layer 12 and the frame sealant.

[0058] Please refer to Figure 1-Figure 2 In one embodiment, the laminated glass 1 includes a first surface 1a and a second surface 1b that are arranged opposite to each other, the first surface 1a is farther away from the ground than the second surface 1b, and the transition layer 13 is arranged between the optical element layer 12 and the first surface 1a.

[0059] The first surface 1a can also be understood as the top edge of the laminated glass 1, and the second surface 1b can also be understood as the bottom edge of the laminated glass 1. In the related art, when the laminated glass 1 is applied to a vehicle, the area between the upper optical element layer 12 and the glass boundary will be exposed to the field of vision during the lifting process of the laminated glass 1, and the color transition will be abrupt, which will reduce the appearance performance of the laminated glass 1 and the user's experience.

[0060] The transition layer 13 is disposed above the optical element layer 12, that is, the transition layer 13 is disposed between the optical element layer 12 and the first surface 1a of the laminated glass 1. During the lifting and lowering process of the laminated glass 1, since the transition layer 13 can maintain a visible light transmittance and color similar to or the same as that of the optical element layer 12, the transition layer 13 and the optical element layer 12 are naturally connected, thereby improving the user experience and solving the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0061] Please refer to Figure 3-Figure 4 In one embodiment, the transition layer 13 is disposed around the periphery of the optical element layer 12 .

[0062] The transition layer 13 is arranged above, below, to the left, and to the right of the optical element layer 12, that is, the transition layer 13 is arranged around the optical element layer 12. The transition layer 13 can maintain a visible light transmittance and color similar to or the same as those of the optical element layer 12, thereby ensuring that no matter how the laminated glass 1 is moved, the transition layer 13 and the optical element layer 12 are naturally connected, further improving the user experience and solving the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0063] Please refer to Figure 1-Figure 3 In one embodiment, the laminated glass 1 further includes a sensor controller 16 electrically connected to the optical element layer 12, wherein the sensor controller 16 is used to obtain change information of the transition layer 13 and to regulate the optical element layer 12 so that the optical element layer 12 has a preset visible light transmittance and a preset color.

[0064] The sensing controller 16 can be a controller having a photoresistor. For example, when the material of the transition layer 13 is selected from a photochromic material, as the amount of radiation received by the transition layer 13 changes, the transition layer 13 has different visible light transmittances and different colors. According to the change of the transition layer 13, the resistance value of the photoresistor also changes, so that the sensing controller 16 obtains the change information of the transition layer 13; the sensing controller 16 adjusts the voltage value applied to the optical element layer 12 according to the change information of the transition layer 13, so that the optical element layer 12 has a visible light transmittance and color similar to or the same as that of the transition layer 13. Optionally, the sensing controller 16 is arranged in the transition layer 13. The sensing controller 16 is arranged between the first glass plate 10 and the second glass plate 15.
