[0043] Optionally, the visible light transmittance of the adhesive layer 12 is ≥70%, or ≥80%, or ≥85%. When the adhesive layer 12 is a transparent thermoplastic polymer, the visible light transmittance of the transparent thermoplastic polymer is greater than or equal to 85%. For example, the visible light transmittance of the adhesive layer 12 can be, but is not limited to, 85%, or 90%, or 95%, etc.

[0044] Optionally, the adhesive layer 12 can be a single-layer structure or a multi-layer structure. Examples of the multi-layer structure can include a double-layer structure, a three-layer structure, a four-layer structure, a five-layer structure, etc. The adhesive layer 12 can also have other functions. For example, adding an infrared absorber to have a sunscreen or heat insulation function, or adding an ultraviolet absorber to have an ultraviolet blocking function, or the plasticizer content of at least one layer of the multi-layer structure is higher to have a sound insulation function.

[0045] The thickness of the inner glass plate 13 is 0.8 mm to 2.5 mm, and the visible light transmittance of the inner glass plate 13 is ≥70%, or ≥80%, or ≥85%, or ≥90%. The inner glass plate 13 is transparent glass, ultra-clear glass or lightly colored glass; the total iron content (calculated as Fe 2 O 3 in the transparent glass (standard white glass) is less than or equal to 0.1%, even less than or equal to 0.05%, and the visible light transmittance of the transparent glass is 80% to 95%.

[0046] The thickness of the outer glass plate 11 and the inner glass plate 13 is 0.8 mm to 2.5 mm, which not only ensures the strength of the laminated glass 1 but also meets the safety standard of the laminated glass 1. In addition, the adhesive layer 12 plays a bonding role and can also improve the toughness and impact resistance of the laminated glass 1.

[0047] The display layer 14 is used to form a display pattern. The display layer 14 can be made of different materials according to actual needs. The display layer 14 is selected from at least one of an electronic ink (E-Ink) module, a Mini-LED module, and an OLED module. In other words, the material of the display layer 14 is selected from at least one of E-Ink, Mini-LED, and OLED. The physical thickness of the display layer 14 is ≤1.5mm, and specific examples include 1.5mm, or 1.2mm, or 1mm, or 0.8mm, or 0.5mm, etc.; preferably, the physical thickness of the display layer 14 is ≤1.2mm; more preferably, the physical thickness of the display layer 14 is ≤0.8mm.

[0048] In this embodiment, a display layer 14 is provided in the laminated glass 1, so that the first display area 103 can perform appearance decoration or external information display on the shielding area 102 as needed, and the internal information display of the second display area 104 in the laminated glass 1 is maintained, thereby making fuller use of the shielding area 102 without raising the shielding area 102, thereby increasing the display area of ​​the laminated glass 1 and improving the appearance performance of the vehicle.

[0049] Optionally, the first display area 103 and the second display area 104 are arranged correspondingly; or, part of the first display area 103 and part of the second display area 104 are arranged correspondingly; or, the first display area 103 and the second display area 104 are arranged alternately.

[0050] Optionally, the display layer 14 includes a protective sublayer and a display sublayer, the protective sublayer covers the display sublayer, the protective sublayer is used to protect the display sublayer, and the display sublayer is used to form the first display image. For example, when the display layer 14 is made of Mini-LED, a TPU protective layer is added to the surface of the display layer 14 so that the display layer 14 forms a multi-layer structure, thereby improving the structural strength of the display layer 14 and extending the service life of the display layer 14.

[0051] Optionally, there is a gap between the display layer 14 and the edge of the laminated glass 1. This arrangement can reduce the contact between the display layer 14 and the moisture in the outside air, protect the display layer 14, and extend the service life of the display layer 14.

[0052] The shielding area 102 formed by the shielding layer 15 is also commonly referred to as the black edge area. The visible light transmittance of the shielding layer 15 is ≤ 0.2%, and specifically, it can be 0.2%, or 0.15%, or 0.1%, or 0.05%, or 0.025%, etc. The material of the shielding layer 15 is selected from at least one of dark ink and opaque polymer film. Among them, the dark ink can be ceramic ink or ultraviolet ink, and the ceramic ink or ultraviolet ink is printed on the third surface by screen printing, inkjet printing and other processes, and the shielding layer 15 is formed after curing or high-temperature sintering. The shielding layer 15 can block the display layer 14 in the thickness direction of the laminated glass 1. The first display area 103 and the second display area 104 are both located in the shielding area 102, so that the shielding layer 15 is used as the display background of the first display image and the second display image, which can better block the external ambient light and avoid unnecessary interference of the line of sight. It can also improve the contrast between the display image and the display background and achieve a higher color gamut, so that the image display is clearer.

[0053] In one embodiment, Figure 3 As shown, the bonding layer 12 includes a first bonding sublayer 121 and a second bonding sublayer 122. Along the stacking direction of the laminated glass 1, the outer glass plate 11, the first bonding sublayer 121, the display layer 14, the second bonding sublayer 122, and the inner glass plate 13 are stacked in sequence.

[0054] Optionally, when the bonding layer 12 includes the first bonding sublayer 121 and the second bonding sublayer 122 , the material of the shielding layer 15 is dark ink.

[0055] The bonding layer 12 is a multilayer structure composed of a first bonding sublayer 121 and a second bonding sublayer 122, and the display layer 14 is sandwiched between the first bonding sublayer 121 and the second bonding sublayer 122. The first bonding sublayer 121 is bonded to the outer glass plate 11 and the display layer 14, and the second bonding sublayer 122 is bonded to the display layer 14 and the shielding layer 15. In this embodiment, by disposing the display layer 14 between the two bonding sublayers, the display layer 14 can be better protected and the reliability of the laminated glass 1 can be improved.

[0056] In another embodiment, if Figure 4 As shown, the display layer 14 and the shielding layer 15 are both embedded in the surface of the adhesive layer 12 facing the inner glass plate 13 , and the shielding layer 15 is disposed on the surface of the display layer 14 facing the inner glass plate 13 .

[0057] Optionally, when the material of the shielding layer 15 is an opaque polymer film, the shielding layer may be a part of the bonding layer 12 , that is, the bonding layer 12 and the shielding layer 15 are formed by splicing an opaque polymer and a transparent polymer.

[0058] The display layer 14 is embedded in the adhesive layer 12, and the surface of the shielding layer 15 close to the inner glass plate 13 is flush with the surface of the adhesive layer 12 close to the inner glass plate 13. For example, a cut gray PVB film is used as the shielding layer 15, and a common transparent adhesive layer 12 is used to splice other transparent areas of the laminated glass 1. In this embodiment, by embedding the display layer 14 and the shielding layer 15 in the adhesive layer 12, the overall thickness of the laminated glass 1 can be reduced, providing more space for the arrangement of other film layers in the laminated glass 1.

[0059] The laminated glass 1 further comprises a light-transmitting area 101, and a shielding area 102 is arranged around the light-transmitting area 101. The visible light transmittance of the light-transmitting area 101 is greater than or equal to 70%, and the visible light transmittance of the shielding area 102 is less than or equal to 5%.

[0060] The shielding area 102 includes a bottom shielding area 1021 located below the light-transmitting area 101, a left shielding area 1022 located on the left side of the light-transmitting area 101, a right shielding area 1023 located on the right side of the light-transmitting area 101, and a top shielding area 1024 located above the light-transmitting area 101. Optionally, the first display area 103 and the second display area 104 are located in the bottom shielding area 1021, and / or the left shielding area 1022, and / or the right shielding area 1023, and / or the top shielding area 1024. Preferably, the first display area 103 and the second display area 104 are both located in the bottom shielding area 1021, and the reflective layer 16 is used to receive the projection light and reflect the projection light.

[0061] In the bottom shielding area 1021, the shielding layer 15 has a size range of ≥200 mm in the extension direction from the edge of the laminated glass 1 to the center of the laminated glass 1, and specific examples include 200 mm, or 225 mm, or 250 mm, or 275 mm, or 300 mm, or 350 mm, etc.

[0062] The laminated glass 1 is applied to a vehicle, and the vehicle includes a vehicle interior part, and the vehicle interior part is arranged on the inner surface of the laminated glass 1 facing the interior of the vehicle, and the inner surface of the laminated glass 1 refers to the surface of the laminated glass 1 facing the interior of the vehicle, and the vehicle interior part is arranged in the shielding area 102. The shielding layer 15 can shield the vehicle body glue and the vehicle interior part in the thickness direction of the laminated glass 1, thereby improving the appearance of the vehicle.

[0063] In another embodiment, the laminated glass 1 further includes a reflective layer 16, which is disposed on the surface of the inner glass plate 13. The reflective layer 16 is farther away from the outer glass plate 11 relative to the shielding layer 15. The reflective layer 16 is located in the second display area 104, and the reflective layer 16 is used to receive and reflect the projection light.

[0064] For example, the reflective layer 16 is disposed on the surface of the inner glass plate 13 facing the bonding layer 12, and the reflective layer 16 includes at least one metal layer, and the metal layer includes a silver layer or an alloy layer containing silver. In this case, the reflective layer 16 is disposed on the third surface, and the thickness of the metal layer is 9nm to 16nm.

[0065] For another example, the reflective layer 16 is disposed on the surface of the inner glass plate 13 facing away from the adhesive layer 12 , and the reflective layer 16 is composed of an overlapping high refractive index layer and a low refractive index layer.

[0066] At this time, the reflective layer 16 is arranged on the fourth surface. The number of high refractive index layers in the reflective layer 16 is at least one, and the number of low refractive index layers in the reflective layer 16 is at least one. For example, the reflective layer 16 is composed of two high refractive index layers and two low refractive index layers, and its film layer structure is "high refractive index layer / low refractive index layer / high refractive index layer / low refractive index layer". Optionally, the reflective layer 16 is arranged corresponding to the display layer 14. In other words, the orthographic projection of the reflective layer 16 on the inner glass plate 13 overlaps with the orthographic projection of the display layer 14 on the inner glass plate 13. Further optionally, the orthographic projection of the display layer 14 on the inner glass plate 13 is located within the orthographic projection of the reflective layer 16 on the inner glass plate 13.

[0067] The reflective layer 16 can receive and reflect the projection light to improve the light reflectivity of the P polarized light and / or the S polarized light at a preset incident angle, and ensure the stability of the display effect under complex light conditions. The preset incident angle can be 57°. In addition, the reflective layer 16 can also enhance the brightness of the projection display, improve the energy utilization rate of the projection device 21, and thus reduce the energy consumption of the projection device 21, which is beneficial to the miniaturization and heat dissipation design of the projection device 21.

[0068] In one embodiment, the reflective layer 16 has a P light reflectivity RLp ≥ 15% for P polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence, specifically 15%, or 18%, or 20%, or 23%, or 25%, or 28%, or 30%, or 35%, or 40%, etc.; preferably, the reflective layer 16 has a P light reflectivity RLp ≥ 20% for P polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence; more preferably, the reflective layer 16 has a P light reflectivity RLp ≥ 25% for P polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence.

[0069] In another embodiment, the reflective layer 16 has an S light reflectivity RLs≥15% for S polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence, and specific examples include 15%, or 18%, or 20%, or 23%, or 25%, or 28%, or 30%, or 35%, or 40%, etc.; preferably, the reflective layer 16 has an S light reflectivity RLs≥20% for S polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence; more preferably, the reflective layer 16 has an S light reflectivity RLs≥25% for S polarized light with a wavelength of 380nm-780nm incident at a preset angle of incidence.

[0070] In another embodiment, the reflective layer 16 has a P-light reflectivity RLp for P-polarized light with a wavelength of 380nm-780nm incident at a preset incident angle, and has an S-light reflectivity RLs for S-polarized light with a wavelength of 380nm-780nm incident at a preset incident angle, RLp≥15% and RLp≥15%, specifically, RLp≥18% and RLp≥18%, or RLp≥20% and RLp≥20%, or RLp≥23% and RLp≥23%, or RLp≥25% and RLp≥25%, or RLp≥30% and RLp≥30%, etc.; preferably, RLp≥20% and RLp≥20%; more preferably, RLp≥25% and RLp≥25%, etc.

[0071] The reflective layer 16 may be adjusted according to the type of projection device 21. For example, when a pure P-light projection device 21 is used, a reflective layer 16 having a light reflectivity RLp greater than or equal to 15% for P-polarized light may be selected. For another example, when a pure S-light projection device 21 is used, a reflective layer 16 having a light reflectivity RLs greater than or equal to 15% for S-polarized light may be selected. For another example, when a P-light and S-light projection device 21 is used, a reflective layer 16 having a light reflectivity RLp greater than or equal to 15% for P-polarized light and a light reflectivity RLs greater than or equal to 15% for S-polarized light may be selected.

[0072] In summary, in this embodiment, by setting the display layer 14 in the laminated glass 1, the first display area 103 of the display layer 14 and the second display area 104 of the shielding area 102 are independent of each other, do not interfere with each other, and do not affect each other. In addition, the display layer 14 not only enhances the display function, but also can be used for exterior decoration to improve the appearance of the black border area, making the vehicle more beautiful as a whole. By displaying external information in the black border area, the interaction between the vehicle and the outside world can be realized, and the intelligent experience can be enhanced.
