[0004] With the development of automotive intelligence, Head-Up Display (HUD) systems are increasingly being used in automobiles. These systems display images, such as driving information, in real time on the windshield. However, because the windshield is made of laminated glass, the light emitted by the HUD's projection source is reflected when it passes through the two surfaces of the laminated glass in contact with the air. This reflection causes the reflected images on the two surfaces to shift, creating two interfering ghost images, resulting in poor image quality projected onto the windshield.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0071] Please refer to Figures 1 to 3 , 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 Cross-sectional view of Line II; Figure 3 An embodiment of this application follows Figure 1A cross-sectional layered structure diagram of 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, with the third surface 121 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 and is used to bond 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. The first region R110 has one or more first functional display areas R111 for displaying a first image P1.

[0072] 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... Figure 1 The cross-sectional view along line II is rotated 90° counterclockwise, separating all structures of the laminated glass 10 and enlarging the thickness of all structures. For ease of description, the altered view is named "along..." Figure 1 A cross-sectional layered structure diagram of Line II. For example, please refer to... Figure 3 , Figure 3 As an embodiment of this application Figure 1 Cross-sectional layered structure diagram of Line II, Figure 3 That is to Figure 2 The laminated glass 10 was obtained by rotating it 90° counterclockwise, separating all its structures, and magnifying the thickness of each structure. Understandably, the subsequent cross-sectional layered structure diagram is also based on this. Figure 2 and Figure 3 The processing method is illustrated below and will not be elaborated upon further.

[0073] The first transparent substrate 110 and the second transparent substrate 120 can be curved plates with light-transmitting properties, such as inorganic glass or plexiglass. Examples of inorganic glass include soda-lime silicate glass, aluminosilicate glass, lithium aluminum silicate glass, or borosilicate glass, while examples of plexiglass include polycarbonate (PC) glass and polymethyl methacrylate (PMMA) glass. The first transparent substrate 110 and the second transparent substrate 120 can be transparent or colored and have light-transmitting properties. The material of the first transparent substrate 110 and the second transparent substrate 120 can be the same or different.

[0074] The light-transmitting area R20 is the region of the laminated glass 10 that allows visible light to pass through. To ensure driving safety after the laminated glass 10 is installed in a vehicle, the visible light transmittance of the light-transmitting area R20 is preferably greater than or equal to 70%. The light-blocking area R10 refers to the region of the laminated glass 10 with lower visible light transmittance, and the light-blocking area R10 is distributed around the perimeter of the laminated glass 10.

[0075] The adhesive film 130 is disposed 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 adhesive film 130 has two structures, which will be described in detail later.

[0076] The laminated glass 10 further includes a light-shielding layer 140 located in the light-blocking region R10. The light-shielding layer 140 can 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 can also be a dark-colored resin film with low light transmittance. Of course, a light-colored resin film with low light transmittance can also be used. Examples of resin films include body-colored PVB, PET, etc.

[0077] 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.

[0078] 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.

[0079] The following describes one application scenario of the laminated glass 10. When the laminated glass 10 is applied to a vehicle 1, it is installed at a certain angle as a windshield. The first transparent substrate 110 of the laminated glass 10 is the substrate exposed outside the vehicle, and the second transparent substrate 120 is the substrate inside the vehicle. To illustrate the beneficial effects of the laminated glass 10 including the light-shielding layer 140, the case where the laminated glass 10 does not include the light-shielding layer 140 will be described first. The projection device inside the vehicle projects a first image P1 onto the laminated glass 10 to form the first image P1 on the second transparent substrate 120. Objects outside the vehicle can also enter the vehicle through the laminated glass 10. The light from the projection device inside the vehicle, projecting the first image P1 onto the laminated glass 10, is incident on the laminated glass 10 from the fourth surface 122 and is reflected by the fourth surface 122 and the first surface 111, respectively, forming reflected light B and reflected light A. The reflected light B and reflected light A do not coincide, resulting in a reflection ghosting. Light from objects outside the vehicle is incident on the laminated glass 10 from the first surface 111 and penetrates the laminated glass 10 to enter the vehicle interior, forming incident light C. Incident light C produces a transmission ghosting due to the tilted installation and parallel thickness of the laminated glass 10. The laminated glass 10 in this embodiment 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 transmission ghosting.

[0080] In summary, the laminated glass 10 provided in this application embodiment has a light-shielding layer 140 located in the light-blocking region R10, which can reduce or even block reflected ghosting and transmitted ghosting. Therefore, the laminated glass 10 provided in this application embodiment can result in high-quality images projected onto it.

[0081] Please refer to again Figure 1 The light-blocking area R10 includes a first area R110 located at the bottom of the light-transmitting area R20, the first area R110 having one or more first functional display areas R111 for displaying a first image P1; a second area R120 located at the top of the light-transmitting area R20; and a third area R130 located on both sides of the light-transmitting area R20, the second area R120 and the third area R130 being used to shield electronic devices or wiring.

[0082] It should be noted that the light blocking area R10 is arranged around the light transmitting area R20, that is, 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 transmitting area R20.

[0083] In this embodiment, the light-blocking area R10 is divided into three regions. The first region R110 is provided with one or more first functional display areas R111. When the first region R110 is provided with multiple first functional display areas R111, the multiple first functional display areas R111 can be set separately, set as one unit, or partially set separately and partially set as one unit. Each first functional display area R111 is used to display one first image P1. Optionally, the total area of ​​the first functional display areas R111 accounts for more than 10% of the first region R110 to achieve a better display effect of the first image P1. The second region R120 and the third region R130 are used to shield electronic devices or circuits installed in later applications.

[0084] Please refer to this again. Figure 4 In one embodiment, the first functional display area R111 is the fourth surface 122, the incident projection light contains 60% to 100% S-polarized light, and the first functional display area R111 has a reflectivity of greater than or equal to 8% for the incident projection light.

[0085] In this embodiment, the projected light preferably contains 100% S-polarized light, which can further improve the reflectivity of the first functional display area R111 to the incident projected light, thereby making the first image P1 clearer.

[0086] Please refer to the above as well. Figure 5 , Figure 6 and Figure 7 , Figure 5 This is another embodiment of the present application. Figure 1 Cross-sectional layered structure diagram of Line II; Figure 6 This is another embodiment of the present application. Figure 1 Cross-sectional layered structure diagram of Line II; Figure 7 This is another embodiment of the present application. Figure 1 A cross-sectional layered structure diagram of the middle II line. The adhesive film 130 is a film of uniform thickness, and the laminated glass 10 further includes a dielectric film 150, which is disposed on the third surface 121 (see...). Figure 6 ), or the fourth surface 122 (refer to Figure 5 ), or encased in the adhesive membrane 130 (see reference ). Figure 7 The dielectric film 150 is located in the first region R110, and the orthographic projection of the dielectric film 150 on the second transparent substrate 120 covers all the first functional display areas R111. The dielectric film 150 has S-polarized light reflection capability.

[0087] In this embodiment, the dielectric film 150 has S-polarized light reflection capability, and the dielectric film 150 is located on the fourth surface 122 (refer to...). Figure 5 ), or the third surface 121 (see Figure 6 ), or encased in the adhesive membrane 130 (see reference ). Figure 7 After being combined with the second transparent substrate 120, the second transparent substrate 120 acquires S-polarized light reflection capability. For example, when the proportion of S-polarized light in the projected light on one side of the second transparent substrate 120 is relatively large, such as 60% to 100%, the reflectivity of the projected light on one side of the second transparent substrate 120 in the light blocking region R10 is relatively large, for example, it can reach 22% when incident at a 60° incident angle. Preferably, the proportion of S-polarized light is 100%, which further weakens or even blocks the reflected light from the first transparent substrate 110. The orthogonal projection of the dielectric 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 on the second transparent substrate 120 by the incident light on one side of the second transparent substrate 120.

[0088] Please refer to the above as well. Figure 5 , Figure 6 and Figure 7 , Figure 5 This is another embodiment of the present application. Figure 1 Cross-sectional layered structure diagram of Line II; Figure 6 This is another embodiment of the present application. Figure 1 Cross-sectional layered structure diagram of Line II; Figure 7 This is another embodiment of the present application. Figure 1 A cross-sectional layered structure diagram of the middle II line. The adhesive film 130 is a film of uniform thickness, and the laminated glass 10 further includes a dielectric film 150, which is disposed on the third surface 121 (see...). Figure 6 ), or the fourth surface 122 (refer to Figure 5 ), or encased in the adhesive membrane 130 (see reference ). Figure 7 The dielectric film 150 is located in the first region R110, and the orthographic projection of the dielectric film 150 on the second transparent substrate 120 covers all the first functional display areas R111. The dielectric film 150 has P-polarized light reflection capability.

[0089] In this embodiment, the dielectric film 150 has P-polarized light reflection capability. The dielectric film 150 may be, but is not limited to, a high refractive index layer, a low refractive index layer, a metal film (1-5 silver), or a laminated polyethylene terephthalate (PET), etc. The dielectric film 150 is located on the fourth surface 122 (refer to...). Figure 5 ), or the third surface 121 (see Figure 6 ), or encased in the adhesive membrane 130 (see reference ). Figure 7 After being combined with the second transparent substrate 120, the second transparent substrate 120 acquires P-polarized light reflection capability. For example, when the proportion of P-polarized light in the projected light on one side of the second transparent substrate 120 is relatively large, such as 60% to 100%, the second transparent substrate 120 reflects P-polarized projected light on one side of the second transparent substrate 120 in the light blocking region R10. For example, this can reach 20% when incident at a 65° angle of incidence, and preferably 100%. This further weakens or even blocks the reflected light from the first transparent substrate 110, which can further improve the brightness and clarity of the reflected light on the second transparent substrate 120 from the incident light on one side of the second transparent substrate 120. It can also enable the driver to observe the first image P1 in the first functional display area R111 while wearing sunglasses.

[0090] Please refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the laminated glass region division structure provided in another embodiment of this application; Figure 9 This is a schematic diagram of the region division structure of laminated glass provided in another embodiment of this application. The laminated glass 10 further includes one or more flexible display screens 160, which are disposed in the first region R110, and each flexible display screen 160 corresponds to one first functional display area R111. The flexible display screen 160 is used to display a first image P1; or one or more first projection light sources 170, which are used to project the first image P1 onto the first functional display area R111, and each first projection light source 170 corresponds to one first functional display area R111.

[0091] Please refer to Figure 8In this embodiment, the first functional display area R111 is provided with the flexible display screen 160. Each flexible display screen 160 corresponds to one first functional display area R111, and each flexible display screen 160 is disposed between the light-shielding layer 140 and the third surface 121 or disposed on 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 / or an OLED display screen. The flexible display screen 160 directly generates images. The first image P1 emitted by the flexible display screen 160 directly passes through the second transparent substrate 120 or does not need to pass through the second transparent substrate 120, without the influence of reflected light from the first transparent substrate 110, further avoiding the formation of ghosting by reflected light from the first transparent substrate 110 and the second transparent substrate 120.

[0092] In another embodiment, please refer to Figure 9 Each of the first projection light sources 170 corresponds to one of the first functional display areas R111, and the first projection light source 170 is disposed on one side of the second transparent substrate 120. Optionally, the S-polarized light content in the first projection light source 170 is 60% to 100%, which, in conjunction with the dielectric film 150 having S-polarized light reflectivity, can improve the clarity of the first image P1. Preferably, the S-polarized light content in the first projection light source 170 is 100%, which can further improve the clarity of the first image P1.

[0093] In another embodiment, when the laminated glass 10 has multiple first functional display areas R111, the flexible display screen 160 and the first projection light source 170 are used in combination. The flexible display screen 160 is configured to correspond to a portion of the first functional display areas R111, and the first projection light source 170 is configured to correspond to the remaining first functional display areas R111. This embodiment, while reducing the ghosting caused by reflected light from the first transparent substrate 110 and the second transparent substrate 120, increases the diversity of the first functional display areas R111, and allows for optimization of the installation of the laminated glass 10 according to actual applications.

[0094] 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 the display background for the first image P1. The light-shielding layer 140 may be, but is not limited to, a dark ink layer or a colored polymer film. Meanwhile, the projection display distance of the first image P1 is 0.5m to 5m.

[0095] Please refer 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] In this embodiment, the thickness of the adhesive film 130 gradually decreases along the direction from the second region R120 toward the first region R110. In other words, the adhesive film 130 is a wedge-shaped film. Optionally, the wedge angle formed by the thickness gradient of the adhesive film 130 is 0.15 mrad to 0.55 mrad, and the orthographic projection of the portion of the adhesive film 130 with the thickness gradient structure onto the second transparent substrate 120 at least covers all of the second functional display areas R211. The second functional display area R211 is part of the fourth surface 122, and the projection light forming the second image P2 contains 60% to 100% S-polarized light. The reflectivity of the second functional display area R211 to the projection light forming the second image P2 incident at 50°-72° is greater than or equal to 8%. Preferably, the projection light forming the second image P2 contains 100% S-polarized light. The adhesive film 130, with its gradually varying thickness, corrects the ghosting of reflected light from the first transparent substrate 110 and the second transparent substrate 120 in the second functional display area R211 through a wedge angle. Furthermore, when the laminated glass 10 has multiple second functional display areas R211, the wedge angles of the adhesive film 130 in different second functional display areas R211 can be equal or unequal. Since the size, shape, and position of each second functional display area R211 differ, and the angle of incidence of the light source is also different, different wedge angles are needed to correct the ghosting of reflected light from the first transparent substrate 110 and the second transparent substrate 120 in the second functional display area R211. Of course, if the setting conditions of each second functional display area R211 are consistent, the same wedge angle can also be used.

[0101] Please refer to Figure 11 In one embodiment, the light-shielding layer 140 is disposed on the third surface 121, and the adhesive film 130 is disposed between the light-shielding layer 140 and the second surface 112. The portion of the adhesive film 130 with a gradient thickness structure has its orthographic projection on the second transparent substrate 120 covering the entire second functional display area R211. The adhesive film 130 can correct the ghosting formed by reflected light from the first transparent substrate 110 and the second transparent substrate 120 in the second functional display area R211, improving the clarity of the second image P2. In another embodiment, please refer to... Figure 12The light-shielding layer 140 is disposed on the second surface 112, and the adhesive film 130 is disposed between the light-shielding layer 140 and the third surface 121. The portion of the adhesive film 130 with a thickness gradient structure has its orthographic projection on the second transparent substrate 120 covering the entire second functional display area R211. The adhesive film 130 can correct the ghosting formed by reflected light from the first transparent substrate 110 and the second transparent substrate 120 in the second functional display area R211, improving the clarity of the second image P2; or, the portion of the adhesive film 130 with a thickness gradient structure... The orthographic projection on the second transparent substrate 120 covers all the first functional display areas R111 and all the second functional display areas R211. The adhesive film 130 can correct the ghosting formed by the reflected light from the first transparent substrate 110 and the second transparent substrate 120 in the first functional display areas R111 and the second functional display areas R211, which not only improves the clarity of the second image P2, but also further improves the clarity of the first image P1, and also improves the manufacturing efficiency of the adhesive film 130 with the first transparent substrate 110 and the second transparent substrate 120.

[0103] Please refer to Figure 13 ,exist Figure 11Based on the illustrated embodiment, the dielectric film 150 is disposed on the fourth surface 122. In one embodiment, when the light source on one side of the fourth surface 122 contains 60% to 100% P-polarized light, the dielectric film 150 has P-polarized light reflection capability, and the P-polarized light reflectivity of the dielectric film 150 is above 10%. At an incident angle of 50°-72°, the first surface 111 of the first transparent substrate 110 has a very low reflectivity for P-polarized light. For example, at an incident angle of 57°, the P-polarized light reflectivity of the first surface 111 is less than 1%, which weakens the reflected light from the first surface 111, that is, further weakens the ghosting of the reflected light from the light source on one side of the fourth surface 122 on the first surface 111 and the fourth surface 122. In another embodiment, when the light source on one side of the fourth surface 122 contains 60% to 100% S-polarized light, the dielectric film 150 has S-polarized light reflection capability, and the S-polarized light reflectivity of the dielectric film 150 is above 28%, weakening the reflected light from the first surface 111.

The dielectric film 150 has S-polarized light anti-reflection capability and a reflectivity of no more than 6%, which weakens the reflected light of the light source on the fourth surface 122 on the fourth surface 122, thereby weakening the ghosting of the reflected light of the light source on the fourth surface 122 on the first surface 111 and the fourth surface 122 in the second functional display area R211.

In another embodiment (such as...) Figure 25 The head-up system includes the first projection light source 170, the second projection light source 190, and the laminated glass 10 described in any embodiment that includes the second functional display area R211.

[0122] In one embodiment, the projection light forming the first image P1 contains 60%-100% P-polarized light, and the projection light forming the second image P2 contains 60%-100% S-polarized light.

[0123] In another embodiment, the projection light forming the first image P1 contains 60%-100% S-polarized light, and the projection light forming the second image P2 contains 60%-100% P-polarized light.

[0124] In another embodiment, the projection light forming the first image P1 contains 60%-100% P-polarized light, and the projection light forming the second image P2 contains 60%-100% P-polarized light.

[0125] In another embodiment, the projection light forming the first image P1 contains 60%-100% S-polarized light, and the projection light forming the second image P2 contains 60%-100% S-polarized light.

[0126] It should be noted that, preferably, the above-mentioned projection light contains 100% S-polarized light or 100% P-polarized light, which can achieve better projection effect.

[0127] Please refer to Figure 27 , Figure 27 This application provides a schematic diagram of a vehicle. The application also provides a vehicle 1, which includes the laminated glass 10 described in any of the above embodiments, and the vehicle 1 further includes a vehicle body 20; the laminated glass 10 is disposed 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 disposed on the outer side of the vehicle 1, and the second transparent substrate 120 is disposed on the inner side of the vehicle 1.

[0128] 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 mounting angle, which is typically 50° to 72°. Without the light-shielding layer 140, on the one hand, the reflected light projected from inside the vehicle 1 onto the first transparent substrate 110 and the second transparent substrate 120 will create a ghost image; on the other hand, objects outside the vehicle 1 passing through the laminated glass 10 will also create a ghost image with the reflected light projected from inside the vehicle 1 onto the laminated glass 10. The light-shielding layer 140 weakens or even eliminates the above ghost image; the dielectric film 150 further weakens or even eliminates the above ghost image and weakens or even eliminates the ghost image effect of the second functional display area R211. When the loading angle can be 60°, the reflection of projected light by the light-transmitting medium film 150 in the first functional display area R111 was tested, and the data are shown in the following two tables.

[0129] Table 1. Reflection data of the first functional display area of ​​the laminated glass without a transparent dielectric film on the projected light.

[0130]

[0131] Table 2 shows the reflection data of projected light from laminated glass with different transparent dielectric films in the first functional display area.

[0132] Transparent dielectric film type Light source type reflectivity Anti-reflective coating ordinary light source 5.1％ P-polarized reflective film P polarized light 11％ S-polarized reflective film S polarized light 22％

[0133] In Table 1, when the light source is a common light source, the emitted light is a random collection of countless polarized rays, so the direction of light intensity deviation cannot be detected during direct observation. This type of light, where the intensity of light waves vibrating in all directions is the same, can also be called natural light. When the light source is P-polarized, the proportion of P-polarized light in the emitted light is 60%–100%. When the light source is S-polarized, the proportion of S-polarized light in the emitted light is 60%–100%. For the light source types in Table 2, please refer to the description in Table 1; it will not be repeated here. The antireflective coating is the aforementioned dielectric film 150 with S-polarized light antireflection capability and low reflectivity (less than 6%); the P-polarized reflective film is the aforementioned dielectric film 150 with P-polarized light reflection capability; and the S-polarized reflective film is the aforementioned dielectric film 150 with S-polarized light reflection capability. As can be seen from the experimental data in the two tables above, in one embodiment, in the first functional display area R111, when the first projection light source 170 is a normal light source and the anti-reflection film is installed, the reflectivity of the fourth surface 122 for the projection of the first projection light source 170 in the first functional display area R111 decreases from 7.5% to 5.1%. In another embodiment, in the first functional display area R111, when the first projection light source 170 is P-polarized light and a P-polarized reflective film is installed, the reflectivity of the fourth surface 122 for the projection of the first projection light source 170 in the first functional display area R111 increases from 0.3% to 11%. In yet another embodiment, in the first functional display area R111, when the first projection light source 170 is S-polarized light and an S-polarized reflective film is installed, the reflectivity of the fourth surface 122 for the projection of the first projection light source 170 in the first functional display area R111 increases from 13% to 22%.

[0134] Optionally, the laminated glass 10 further comprises a transparent conductive layer, which is installed between the first transparent substrate 110 and the second transparent substrate 120. The transparent conductive layer has at least one of the ability to reflect infrared rays for heat insulation and a heating function, and the transparent conductive layer covers at least 80% of the light-transmitting area R20.

[0135] 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 vehicle speed, fuel level in the fuel tank, or engine speed; Optionally, the display distance of the second image P2 is 7.5m or more, and the second image P2 can be a larger image display such as route navigation, speeding warning, or obstacle warning.

[0136] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
