[0004] With the development of automobile intelligence, head-up display (HUD) systems are increasingly applied to automobiles. The HUD system displays images, such as driving information, on the front windshield in real time.

The reflected images on the two surfaces will be offset, thereby forming two ghost images that interfere with each other, resulting in low image quality projected onto the front windshield. SUMMARY

[0071] Please refer to Figures 1 to 3 , Figure 1 The schematic diagram of the region division structure of the laminated glass provided by the embodiment of the present application; Figure 2 For another embodiment of the present application, the cross-sectional view along Figure 1 line I-I in the embodiment of the present application. Figure 3 For another embodiment of the present application, the cross-sectional view along Figure 1Cross-sectional layered structure diagram along line II. The present application provides a laminated glass 10, comprising 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 being 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 area R110 located at the bottom of the light-transmitting area R20. The first area 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. In order to conveniently and clearly illustrate the layered structure of the laminated glass 10, this application will be described as follows: Figure 1 The cross-sectional view along line II is rotated 90° counterclockwise, and all structures of the laminated glass 10 are separated and the thickness of all structures is magnified. For the convenience of description, the changed view is named along line II. Figure 1 Cross-sectional layered structure diagram of line II. For example, please refer to Figure 3 , Figure 3 For an embodiment of this application Figure 1 The cross-sectional layered structure diagram of the middle II line, Figure 3 That is to Figure 2 The laminated glass 10 is rotated 90° counterclockwise and all structures are separated and the thickness of all structures is magnified. Figure 2 and Figure 3 The processing method is illustrated and will not be described in detail later.

[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 organic glass. Examples of inorganic glass include soda-lime silicate glass, aluminosilicate glass, lithium aluminosilicate glass, or borosilicate glass. Examples of organic glass 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 light-transmitting. The material of the first transparent substrate 110 and the material of the second transparent substrate 120 can be the same or different.

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

[0075] The adhesive film 130 is disposed between the first transparent substrate 110 and the second transparent substrate 120 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 also 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, while the colored polymer film is disposed between the second surface 112 and the third surface 121. The light-shielding layer 140 has a low transmittance of projected light. The light-shielding layer 140 is supported on the first transparent substrate 110 or the second transparent substrate 120 and located in the light-blocking region R10. The light-shielding layer 140 can be formed in the light-blocking region R10 using methods such as printing ink. 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%. The light-shielding layer 140 can also be made of a dark resin film with low transmittance, or a light resin film with low transmittance. Examples of such resin films include body-colored PVB, PET, and the like.

[0077] In one embodiment, please refer to Figure 3 , Figure 3 For an embodiment of this application Figure 1 The light shielding layer 140 is disposed on the second surface 112. In another embodiment, please refer to Figure 4 ,Figure 4 For another embodiment of the present application Figure 1 The cross-sectional layered structure of the I-I line. The light-shielding layer 140 is arranged on the third surface 121.

[0078] Specifically, in one aspect, if the light-shielding layer 140 is not included in the laminated glass 10, the projection light rays of the first image P1 projected by the projection device in the vehicle to the laminated glass 10 from the fourth surface 122 are reflected by the first surface 111 of the first transparent substrate 110, thereby forming the reflected light A. Accordingly, the projection light rays incident to the laminated glass 10 are reflected by the fourth surface 122 of the second transparent substrate 120 to enter the human eye. For the convenience of description, the projection light rays reflected by the fourth surface 122 are named as reflected light B. The reflected light B forms the main image visible to the human eye, and the reflected light A forms the sub-image visible to the human eye, and the sub-image and the main image have a certain offset distance, that is, the ghosting phenomenon occurs. The laminated glass 10 of the embodiment of the present 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 the reflected light B. At the same time, due to the low projection light transmittance of the light-shielding layer 140, the light-shielding layer 140 can be used as the display background of the main image, which improves the recognition degree of the main image and the contrast with the environmental brightness, and can significantly improve the display quality of the main image.

[0079] 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.

[0080] 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.

[0081] 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 on both sides of the light transmission area R20. The second area R120 and the third area R130 are used to shield electronic devices or wiring.

[0082] 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.

[0083] 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.

[0084] 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%.

[0085] 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.

[0086] Please refer again to Figure 5 , Figure 6 and Figure 7 , Figure 5 is a sectional layered structure view of the embodiment of the present application along the line I-I in Figure 1 ; Figure 6 is a sectional layered structure view of the embodiment of the present application along the line I-I in Figure 1 ; Figure 7 is a sectional layered structure view of the embodiment of the present application along the line I-I in Figure 1 . The adhesive 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 adhesive film 130 (see Figure 7 ), and the dielectric film 150 is located in the first region R110, the dielectric film 150 covers all the first functional display regions R111 in orthographic projection on the second transparent substrate 120, and the dielectric film 150 has S-polarized light reflection capability.

[0087] 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 one 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 one 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.

[0089] 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 is arranged 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%. Further weakening or even blocking the reflected light of the first transparent substrate 110 can further improve the brightness and clarity of the reflected light of the incident light on the second transparent substrate 120 on the side of the second transparent substrate 120. It can also achieve the first image P1 of the first functional display area R111 that can be observed by the driver wearing sunglasses.

[0091] 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 shading layer 140 and the third surface 121 or the fourth surface 122.

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.

[0092] In another embodiment, please refer 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.

On the basis of weakening the ghosting caused by the reflection of the first transparent substrate 110 and the second transparent substrate 120, this embodiment increases the diversity of the display of the first functional display area R111, and can optimize the installation of the laminated glass 10 according to the actual application.

[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 shading layer 140, so that the shading layer 140 can serve as a display background of the first image P1. The shading 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.

[0095] Please refer to Figure 10 , Figure 10Schematic diagram of the region division structure of laminated glass provided in another embodiment of the present application: The light-transmitting region R20 further comprises a main viewing region R210, the lower boundary of the main viewing region R210 being at least 25 mm 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 25 mm higher than the upper boundary of the first area R110, so as to avoid the optical sensitivity area and prevent light distortion between the first area R110 and the main field of view R210, thereby preventing interference with the imaging in the first area R110 and the main field of view R210.

[0097] Please refer again Figure 10 The main visual field R210 also has one or more second function display areas R211. The second function display areas R211 are used to display a 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. 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, thereby 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.

[0100] 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 a part of the fourth surface 122, the projection light rays forming the second image P2 contain 60% to 100% S-polarized light, and the reflectivity of the second functional display regions R211 to the projection light rays forming the second image P2 incident at 50° to 72° is greater than or equal to 8%. Preferably, the projection light rays forming the second image P2 contain 100% S-polarized light. The thickness gradually decreasing adhesive film 130 corrects the ghosting of the reflection light rays of the first transparent substrate 110 and the second transparent substrate 120 in the second functional display regions R211 by 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 in 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 incidence is also different, so different wedge angles are needed to correct the ghosting of the reflection light rays of the first transparent substrate 110 and the second transparent substrate 120 in 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.

[0127] 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.

[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 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 in 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 form ghosting with the reflected light in the vehicle 1 projected on the laminated glass 10. The arrangement of the light shielding layer 140 weakens or even eliminates the ghosting described above; the arrangement of the medium film 150 further weakens or even eliminates the ghosting described above and weakens or even eliminates 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 shown in the following two tables.

[0129] Table 1 Reflection data of the first functional display area on the light shielding area of the laminated glass without transparent medium film.

[0130] Light source type Reflectivity General light source 7.5％ P-polarized light 0.3％ S-polarized light 13％

[0131] Table 2 Reflection data of the first functional display area on the light shielding area of the laminated glass with different transparent medium films.

[0132] 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％

[0133] 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.

[0134] 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.

[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 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.

[0136] 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.
