[0055] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the laminated glass region division structure provided in an embodiment of this application; Figure 2 As an embodiment of this application, along Figure 1 A cross-sectional view along line II. This application provides a laminated glass 10, which includes a first transparent substrate 110, a second transparent substrate 120, and an adhesive film 130. The first transparent substrate 110 has a first surface 111 and a second surface 112 disposed opposite to each other. The second transparent substrate 120 has a third surface 121 and a fourth surface 122 disposed opposite to each other, wherein the third surface 121 is disposed adjacent to the second surface 112 relative to the fourth surface 122. The laminated glass 10 has a light-transmitting region R20 and a light-blocking region R10 surrounding at least a portion of the periphery of the light-transmitting region R20. The adhesive film 130 is located between the second surface 112 and the third surface 121 for bonding the first transparent substrate 110 and the second transparent substrate 120. The visible light transmittance of the light-transmitting area R20 is greater than or equal to 70%, and the visible light transmittance of the light-blocking area R10 is less than or equal to 5%. The light-blocking area R10 includes a first region R110 located at the bottom of the light-transmitting area R20.

[0056] In one embodiment, the first transparent substrate 110 and the second transparent substrate 120 are tightly connected by the adhesive film 130. To facilitate and clearly illustrate the layered structure of the laminated glass 10, this application will follow...

[0057] The first transparent substrate 110 and the second transparent substrate 120 can be curved plate members with light transmission performance, such as inorganic glass or organic glass. The inorganic glass can be exemplified by soda-lime-silica glass, alumino-silicate glass, lithium-alumino-silicate glass or borosilicate glass. The organic glass can be exemplified by polycarbonate (PC) glass, polymethyl methacrylate (PMMA) glass, etc. The first transparent substrate 110 and the second transparent substrate 120 can be transparent or colored and have light transmission performance. The material of the first transparent substrate 110 can be the same as or different from the material of the second transparent substrate 120.

[0058] The light transmission region R20 is a region of the laminated glass 10 that can transmit visible light. In order to ensure the driving safety of the laminated glass 10 after being installed on a vehicle, the visible light transmittance of the light transmission region R20 is preferably greater than or equal to 70%. The light blocking region R10 is a region of the laminated glass 10 with low visible light transmittance, and the light blocking region R10 is distributed in the peripheral edge region of the laminated glass 10.

[0059] The bonding film 130 is arranged between the first transparent substrate 110 and the second transparent substrate 120, and is used to bond the first transparent substrate 110 and the second transparent substrate 120. The bonding film 130 has two structures, which will be described in detail later.

[0060] The light-blocking region R10 includes a light-shielding layer 140, which may be a dark ink layer or a colored polymer film. The dark ink layer is disposed on the second surface 112 and / or the third surface 121, and the colored polymer film is disposed between the second surface 112 and the third surface 121. The light-shielding layer 140 has low projected light transmittance. The light-shielding layer 140 is supported on the first transparent substrate 110 or the second transparent substrate 120 and is located in the light-blocking region R10. The light-shielding layer 140 can be formed in the light-blocking region R10 by means of printing ink or the like. Optionally, the projected light transmittance of the light-shielding layer 140 is less than or equal to 5%, preferably less than or equal to 1%. Optionally, the light-shielding layer 140 may also be a dark-colored resin film with low transmittance, or a light-colored resin film with low transmittance. Examples of resin films include body-colored PVB and PET.

[0061] In one embodiment, please continue to refer to Figure 3 , Figure 3 As an embodiment of this application Figure 1 A cross-sectional layered structure diagram of line II. The light-shielding layer 140 is disposed on the second surface 112. In another embodiment, please refer to... Figure 4 , Figure 4 This is another embodiment of the present application. Figure 1 A cross-sectional layered structure diagram of line II. The light-shielding layer 140 is disposed on the third surface 121.

[0062] Specifically, on the one hand, if the laminated glass 10 does not include the light-shielding layer 140, the projection light of the first image P1 projected by the projection device in the vehicle onto the laminated glass 10 is incident on the fourth surface 122 and reflected by the first surface 111 of the first transparent substrate 110, thereby forming the reflected light A. Correspondingly, the projection light incident on the laminated glass 10 is reflected by the fourth surface 122 of the second transparent substrate 120 and enters the human eye. For ease of description, the projection light reflected by the fourth surface 122 is named reflected light B. The reflected light B forms a primary image visible to the human eye, and the reflected light A forms a secondary image visible to the human eye. There is a certain offset distance between the secondary image and the primary image, i.e., a ghosting phenomenon occurs. The laminated glass 10 of this application includes the light-shielding layer 140, which can reduce or even block the reflected light A, thereby weakening or even blocking the ghosting caused by the reflected light A and reflected light B. Meanwhile, since the light-shielding layer 140 has low light transmittance, it can serve as a display background for the main image, improving the recognition of the main image and its contrast with the ambient brightness, thus significantly improving the display quality of the main image.

[0063] The application will be described below in an application scenario of the laminated glass 10. When the laminated glass 10 is applied to the vehicle 1, the laminated glass 10 is installed on the vehicle 1 as a front windshield glass at a certain inclination angle. The first transparent substrate 110 in the laminated glass 10 is the substrate of the laminated glass 10 exposed outside the vehicle, and the second transparent substrate 120 is the substrate of the laminated glass 10 inside the vehicle. In order to illustrate the beneficial effects of the laminated glass 10 including the light shielding layer 140, the laminated glass 10 without the light shielding layer 140 will be introduced first. The projection device inside the vehicle projects the first image P1 to the laminated glass 10 to form the first image P1 on the second transparent substrate 120. The object outside the vehicle also enters the vehicle through the laminated glass 10. The light of the first image P1 projected by the projection device inside the vehicle to the laminated glass 10 is incident to the laminated glass 10 from the fourth surface 122 and is reflected by the fourth surface 122 and the first surface 111 respectively to form reflected light B and reflected light A, which do not coincide to produce reflection ghosting. The light of the object outside the vehicle is incident to the laminated glass 10 from the first surface 111 and penetrates the laminated glass 10 to enter the vehicle to form incident light C, which produces transmission ghosting due to the inclined installation and parallel thickness of the laminated glass 10. The laminated glass 10 of the application includes the light shielding layer 140, which can reduce or even block the reflected light A and the incident light C, thereby weakening or even blocking the reflection ghosting and the transmission ghosting.

[0064] In summary, the laminated glass 10 provided by the application has the light shielding layer 140 in the light blocking area R10, which can reduce or even block the reflection ghosting and the transmission ghosting. Therefore, the laminated glass 10 provided by the application can make the projected image have a higher quality.

[0065] Please refer to Figure 1 The light blocking area R10 includes a first area R110, a second area R120, and a third area R130. The first area R110 is located at the bottom of the light transmission area R20, has one or more first functional display areas R111 for displaying the first image P1; the second area R120 is located at the top of the light transmission area R20; and the third area R130 is located at the side of the light transmission area R20, and the second area R120 and the third area R130 are used to shield electronic devices or wiring.

[0066] It should be noted that the light blocking area R10 is arranged around the light transmission area R20, i.e. the first area R110, the second area R120, and the third area R130 are located in the light blocking area R10 and surround the light transmission area R20.

[0067] In the embodiment, the light blocking region R10 is divided into three regions, the first region R110 is provided with one or more first functional display regions R111, when the first region R110 is provided with multiple first functional display regions R111, the multiple first functional display regions R111 can be separately provided, or integrally provided, or partially separately provided and partially integrally provided, and each of the first functional display regions R111 is correspondingly used for displaying a first image P1. Optionally, the total area of the first functional display regions R111 accounts for more than 10% of the first region R110, so as to achieve better display effect of the first image P1. The second region R120 and the third region R130 are used for shielding electronic devices or circuits installed in later applications.

[0068] Please refer again to Figure 4 . In an embodiment, the first functional display region R111 is the fourth surface 122, the incident projection light contains 60% to 100% S-polarized light, and the reflectivity of the first functional display region R111 to the incident projection light is greater than or equal to 8%.

[0069] In the embodiment, the projection light preferably contains 100% S-polarized light, which can further improve the reflectivity of the first functional display region R111 to the incident projection light, so as to make the first image P1 clearer.

[0070] Please refer again to Figure 5 , Figure 6 and Figure 7 , Figure 5 is a sectional layered structure view of the embodiment along the line I-I in Figure 1 . Figure 6 is a sectional layered structure view of the embodiment along the line I-I in Figure 1 . Figure 7 is a sectional layered structure view of the embodiment along the line I-I in Figure 1 . The bonding film 130 is an equal-thickness film, the laminated glass 10 further comprises a dielectric film 150, the dielectric film 150 is arranged on the third surface 121 (see Figure 6 ), or the fourth surface 122 (see Figure 5 ), or is wrapped in the bonding film 130 (see Figure 7 ), and the dielectric film 150 is located in the first region R110, the dielectric film 150 has a normal projection on the second transparent substrate 120 covering all the first functional display regions R111, and the dielectric film 150 has S-polarized light reflection capability.

[0071] In the embodiment, the medium film 150 has the S-polarized light reflection ability, and after the medium film 150 is combined with the second transparent substrate 120 at the fourth surface 122 (see Figure 5 ), or the third surface 121 (see Figure 6 ), or is wrapped in the bonding film 130 (see Figure 7 ), the second transparent substrate 120 has the S-polarized light reflection ability. For example, when the S-polarized light accounts for a large proportion in the light projected from the side of the second transparent substrate 120, such as 60% to 100%, the reflectivity of the second transparent substrate 120 to the light projected from the side of the second transparent substrate 120 at the light blocking area R10 is large, such as 22% at the incident angle of 60°, and the preferred S-polarized light accounts for 100%, which further weakens or even blocks the reflected light of the first transparent substrate 110. The orthographic projection of the medium film 150 on the second transparent substrate 120 covers all the first functional display areas R111, which can further improve the brightness and clarity of the reflected light of the second transparent substrate 120.

The bonding film 130 is an equal-thickness film, the laminated glass 10 further includes a medium film 150, the medium film 150 is arranged at the third surface 121 (see Figure 6 ), or the fourth surface 122 (see Figure 5 ), or is wrapped in the bonding film 130 (see Figure 7 ), and the medium film 150 is located in the first area R110, the orthographic projection of the medium film 150 on the second transparent substrate 120 covers all the first functional display areas R111, and the medium film 150 has the P-polarized light reflection ability.

[0073] In the embodiment, the medium film 150 has the P-polarized light reflection ability, and the medium film 150 can be, but is not limited to, a high-refractive layer, a low-refractive layer, a metal film (1-5 silver), or a laminated polyethylene terephthalate (PET), etc. The medium film 150 has the P-polarized light reflection ability at the fourth surface 122 (seeFigure 5 ), or the third surface 121 (see Figure 6 ), or wrapped in the bonding film 130 (see Figure 7 ) and the second transparent substrate 120, so that the second transparent substrate 120 has P-polarized light reflection ability. For example, when the P-polarized light in the light projected from one side of the second transparent substrate 120 accounts for a large proportion, such as 60% to 100%, the second transparent substrate 120 has P-polarized light reflection on the light blocking area R10 on the side of the second transparent substrate 120, such as 20% at an incident angle of 65°, and the preferred P-polarized light accounts for 100%. The reflection of the first transparent substrate 110 is further weakened or even blocked, which can further improve the brightness and clarity of the reflected light on the second transparent substrate 120. The driver wearing sunglasses can also observe the first image P1 of the first functional display area R111.

[0074] Please refer to Figure 8 and Figure 9 , Figure 8 is a schematic diagram of the area division structure of the laminated glass provided by another embodiment of the present application; Figure 9 is a schematic diagram of the area division structure of the laminated glass provided by another embodiment of the present application. The laminated glass 10 further comprises one or more flexible display screens 160, the flexible display screen 160 is arranged in the first area R110, and each flexible display screen 160 corresponds to one first functional display area R111, and the flexible display screen 160 is used to display the first image P1; or one or more first projection light sources 170, the first projection light source 170 is used to project the first image P1 to the first functional display area R111, and each first projection light source 170 corresponds to one first functional display area R111.

[0075] Please refer to Figure 8In the embodiment, the first functional display area R111 is provided with the flexible display screen 160, each of the flexible display screen 160 corresponds to one of the first functional display area R111, and each of the flexible display screen 160 is arranged between the light shielding layer 140 and the third surface 121 or the fourth surface 122. The flexible display screen 160 can be, but is not limited to, a MiniLED display screen, a MicroLED display screen or an OLED display screen. The flexible display screen 160 adopts a direct image generation form, the first image P1 emitted by the flexible display screen 160 directly transmits through the second transparent substrate 120 or does not need to transmit through the second transparent substrate 120, without the influence of the reflected light of the first transparent substrate 110, further avoiding the ghosting caused by the reflection of the first transparent substrate 110 and the second transparent substrate 120.

[0076] In another embodiment, referring to Figure 9 , each of the first projection light source 170 corresponds to one of the first functional display area R111, and the first projection light source 170 is arranged on one side of the second transparent substrate 120. Optionally, the proportion of S-polarized light in the first projection light source 170 is 60% to 100%, which can improve the definition of the first image P1 in cooperation with the medium film 150 having the S-polarized light reflection capability. Preferably, the proportion of S-polarized light in the first projection light source 170 is 100%, which can further improve the definition of the first image P1.

[0077] In yet another embodiment, when the laminated glass 10 has a plurality of the first functional display area R111, the flexible display screen 160 and the first projection light source 170 are used in combination, a part of the flexible display screen 160 corresponds to a part of the first functional display area R111, and the other part of the first projection light source 170 corresponds to the remaining first functional display area R111. This embodiment further increases the diversity of the first functional display area R111 on the basis of weakening the ghosting caused by the reflection of the first transparent substrate 110 and the second transparent substrate 120, and can optimize the installation of the laminated glass 10 according to the actual application.

[0078] It should be noted that the flexible display screen 160 or the first functional display area R111 is closer to the fourth surface 122 than the light shielding layer 140, so that the light shielding layer 140 can serve as a display background of the first image P1. The light shielding layer 140 can be, but is not limited to, a dark ink layer or a colored polymer film. At the same time, the projection display distance of the first image P1 is 0.5m to 5m.

[0079] Referring to Figure 10 , Figure 10This is a schematic diagram of the laminated glass region division structure provided in another embodiment of this application. The light-transmitting region R20 also has a main viewing area R210, the lower boundary of which is at least 25mm higher than the upper boundary of the first region R110.

[0080] In this embodiment, the lower boundary of the main field of view R210 is at least 25mm higher than the upper boundary of the first region R110. This avoids the optically sensitive area and prevents optical distortion between the first region R110 and the main field of view R210, which would interfere with the imaging in the first region R110 and the main field of view R210.

[0081] Please refer to this again. Figure 10 The main field of view R210 also has one or more second functional display areas R211, which are used to display the second image P2, and the projection display distance of the second image P2 is more than 7.5m.

[0082] In this embodiment, a second functional display area R211 is added to the laminated glass 10, and the area of ​​the second functional display area R211 is larger than that of the first functional display area R111, enabling the laminated glass 10 to display a larger second image P2, thus enriching the image display of the laminated glass 10. The projection light forming the first image P1 is incident on the projection display area of ​​the first functional display area R111 at an angle of 50°-72°, and the projection display area of ​​the first functional display area R111 has a reflectivity greater than or equal to 4% for the projection light forming the first image P1; the projection light forming the second image P2 is incident on the projection display area of ​​the second functional display area R211 at an angle of 50°-72°, and the projection display area of ​​the second functional display area R211 has a reflectivity greater than or equal to 8% for the projection light forming the second image P2.

[0083] Please refer to Figure 11 and Figure 12 , Figure 11 This is another embodiment of the present application. Figure 10 Cross-sectional layered structure diagram of Line II; Figure 12 This is another embodiment of the present application. Figure 10 A cross-sectional layered structure diagram of line II. The thickness of the adhesive film 130 gradually decreases along the direction from the second region R120 to the first region R110, and the orthographic projection of the adhesive film 130 on the second transparent substrate 120 covers all the second functional display areas R211.

[0084] In the embodiment, the thickness of the adhesive film 130 gradually decreases from the second region R120 to the first region R110. In other words, the adhesive film 130 is a wedge-shaped film. Optionally, the wedge angle of the adhesive film 130 due to the thickness gradually decreasing is 0.15 mrad to 0.55 mrad, and the normal projection of the portion of the adhesive film 130 having the thickness gradually decreasing structure on the second transparent substrate 120 covers all the second functional display regions R211. The second functional display regions R211 are the fourth surface 122, and the projection light forming the second image P2 contains 60% to 100% S-polarized light, and the reflectivity of the second functional display regions R211 to the projection light forming the second image P2 incident at 50° to 72° is greater than or equal to 8%. Preferably, the projection light forming the second image P2 contains 100% S-polarized light. The thickness gradually decreasing adhesive film 130 corrects the ghost image of the reflected light of the first transparent substrate 110 and the second transparent substrate 120 on the second functional display regions R211 through the wedge angle. Meanwhile, when the laminated glass 10 has a plurality of the second functional display regions R211, the wedge angles of the adhesive film 130 on different second functional display regions R211 can be equal or unequal. The size, shape and position of each second functional display region R211 are different, and the angle of the light source incident is also different, so different wedge angles are needed to correct the ghost image of the reflected light of the first transparent substrate 110 and the second transparent substrate 120 on the second functional display regions R211. Of course, if the setting conditions of each second functional display region R211 are consistent, the same wedge angle can also be used.

[0085] Please refer to Figure 11 In an embodiment, the light shielding layer 140 is arranged on the third surface 121, the adhesive film 130 is arranged between the light shielding layer 140 and the second surface 112, the normal projection of the portion of the adhesive film 130 having the thickness gradually decreasing structure on the second transparent substrate 120 covers all the second functional display regions R211, and the adhesive film 130 can correct the ghost image of the reflected light of the first transparent substrate 110 and the second transparent substrate 120 on the second functional display regions R211, thereby improving the clarity of the second image P2. In another embodiment, please refer to Figure 12The light shielding layer 140 is arranged on the second surface 112, the bonding film 130 is arranged between the light shielding layer 140 and the third surface 121, and the normal projection of the portion with the thickness gradient structure of the bonding film 130 on the second transparent substrate 120 covers all the second functional display areas R211. The bonding film 130 can correct the ghost image formed by the reflected light of the first transparent substrate 110 and the second transparent substrate 120 in the second functional display area R211, and improve the definition of the second image P2. Alternatively, the normal projection of the portion with the thickness gradient structure of the bonding film 130 on the second transparent substrate 120 covers all the first functional display areas R111 and all the second functional display areas R211. The bonding film 130 can correct the ghost image formed by the reflected light of the first transparent substrate 110 and the second transparent substrate 120 in the first functional display area R111 and the second functional display area R211, which not only improves the definition of the second image P2, but also further improves the definition of the first image P1, and improves the manufacturing efficiency of the bonding film 130, the first transparent substrate 110 and the second transparent substrate 120.

[0104] The present application provides a head-up display system, in one embodiment (e.g. Figure 9 ), the head-up display system comprises the first projection light source 170 and the laminated glass 10 according to any of the embodiments comprising only the first functional display area R111.

[0108] In yet another embodiment, the projection light forming the first image P1 comprises 60%-100% S-polarized light, and the projection light forming the second image P2 comprises 60%-100% S-polarized light.

[0109] It should be noted that, preferably, the projection light comprises 100% S-polarized light or 100% P-polarized light, which can achieve better projection effect.

[0110] Reference is made to Figure 27 , Figure 27 A vehicle schematic is provided. A vehicle 1 is also provided, which comprises the laminated glass 10 according to any of the embodiments described above, and the vehicle 1 further comprises a vehicle body 20; the laminated glass 10 is arranged on the vehicle body 20. The laminated glass 10 is described above and will not be repeated here. When the laminated glass 10 is applied to the vehicle 1, the first transparent substrate 110 is arranged on the outside of the vehicle 1, and the second transparent substrate 120 is arranged on the inside of the vehicle 1.

[0111] In this embodiment, the vehicle 1 can be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a van, a bus, a truck, etc. The angle between the laminated glass 10 and the vertical plane is called the vehicle installation angle, and the vehicle installation angle is usually 50°-72°. Without the light shielding layer 140, on the one hand, the reflected light inside the vehicle 1 projected on the first transparent substrate 110 and the second transparent substrate 120 will form ghosting, and on the other hand, the object outside the vehicle 1 will pass through the laminated glass 10 and form ghosting with the reflected light inside the vehicle 1 projected on the laminated glass 10. The arrangement of the light shielding layer 140 weakens or even eliminates the above ghosting; the arrangement of the medium film 150 further weakens or even eliminates the above ghosting and the ghosting effect of the second functional display area R211. When the vehicle installation angle can be 60°, the light transmission medium film 150 is tested on the reflection of the projected light in the first functional display area R111, and the data are as follows in the two tables.

[0112] Table 1 Reflection data of the first functional display area on the light blocking area of the laminated glass without transparent medium film on the projected light.

[0113] Light source type Reflectivity General light source 7.5％ P-polarized light 0.3％ S-polarized light 13％

[0114] Table 2 Reflection data of the first functional display area of the laminated glass with different transparent medium films on the projected light.

[0115] Transparent dielectric film type Light source type Reflectivity Anti-reflective film General light source 5.1％ P-polarized light reflective film P-polarized light 11％ S-polarized light reflective film S-polarized light 22％

[0116] In Table 1, when the light source type is ordinary light source, the light emitted by the ordinary light source is an irregular set of countless polarized light, so that the light intensity cannot be found to be biased in any direction when directly observed. Such light with the same light wave intensity along each direction can also be called natural light. When the light source type is P-polarized light, the P-polarized light accounts for 60% to 100% in the light emitted by the light source. When the light source type is S-polarized light, the S-polarized light accounts for 60% to 100% in the light emitted by the light source. In Table 2, the light source type is described in Table 1, and will not be repeated here. The anti-reflection film is the medium film 150 mentioned above with S-polarized light anti-reflection ability and low reflectivity (less than 6%); the P-polarized light reflection film is the medium film 150 mentioned above with P-polarized light reflection ability; and the S-polarized light reflection film is the medium film 150 mentioned above with S-polarized light reflection ability. As can be seen from the test data of the above two tables, in one embodiment, in the first functional display area R111, when the first projection light source 170 is an ordinary light source, the reflectivity of the fourth surface 122 to the projection of the first projection light source 170 in the first functional display area R111 is reduced from 7.5% to 5.1% after the anti-reflection film is installed. In another embodiment, in the first functional display area R111, when the first projection light source 170 is P-polarized light, the reflectivity of the fourth surface 122 to the projection of the first projection light source 170 in the first functional display area R111 is increased from 0.3% to 11% after the P-polarized light reflection film is installed. In yet another embodiment, in the first functional display area R111, when the first projection light source 170 is S-polarized light, the reflectivity of the fourth surface 122 to the projection of the first projection light source 170 in the first functional display area R111 is increased from 13% to 22% after the S-polarized light reflection film is installed.

[0117] Optionally, the laminated glass 10 further has a transparent conductive layer installed between the first transparent substrate 110 and the second transparent substrate 120, the transparent conductive layer has at least one of the heat insulation ability of reflecting infrared rays and the heating function, and the transparent conductive layer covers more than 80% of the light transmission area R20.

[0118] Optionally, the display distance of the first image P1 is 0.5m to 5m, and the first image P1 can be key information such as driving speed, mailbox oil amount, or engine speed. Optionally, the display distance of the second image P2 is more than 7.5m, and the second image P2 can be larger image display such as route navigation, overspeed warning, or obstacle warning.

[0119] Although the embodiments of the present application have been shown and described above, it is to be understood that the above-described embodiments are merely exemplary, and are not to be construed as limiting the present application, and that modifications, substitutions, replacements and variations of the above-described embodiments can be made by those skilled in the art within the scope of the present application, and such improvements and refinements are also considered to be within the scope of protection of the present application.
