Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a laminated glass area dividing structure provided in an embodiment of the present application; FIG. 2 is a cross-sectional view taken along line I-I of FIG. 1 according to an embodiment of the present application. The present application provides a laminated glass 10, the laminated glass 10 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 opposite to each other. The second transparent substrate 120 has a third surface 121 and a fourth surface 122 disposed opposite to each other, and the third surface 121 is disposed adjacent to the second surface 112 compared to the fourth surface 122. The laminated glass 10 has a light-transmitting region R20 and a light-blocking region R10 surrounding at least part 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 for adhering the first transparent substrate 110 and the second transparent substrate 120. The visible light transmittance of the light transmitting region R20 is greater than or equal to 70%, the visible light transmittance of the light blocking region R10 is less than or equal to 5%, and the light blocking region R10 includes a first region R110 at the bottom of the light transmitting region R20, the first region R110 having one or more first functional display regions R111 for displaying a first image P1.

In one embodiment, the first transparent substrate 110 and the second transparent substrate 120 are closely connected by the adhesive film 130. For convenience and clarity of illustrating the layered structure of the laminated glass 10, the present application will rotate counterclockwise by 90 ° in a sectional view along line I-I in fig. 1, and separate all the structures of the laminated glass 10 and enlarge the thicknesses of all the structures, and for convenience of description, the figure after the change will be named as a sectional layered structure diagram along line I-I in fig. 1. For example, referring to fig. 3, fig. 3 is a cross-sectional layered structure view along line I-I of fig. 1 according to an embodiment of the present application, and fig. 3 is a view obtained by rotating fig. 2 counterclockwise by 90 °, separating all structures of the laminated glass 10, and enlarging the thickness of all structures. It is to be understood that the cross-sectional layered structure diagram described later is also illustrated with reference to the processing manner of fig. 2 and 3, and is not described again later.

The first transparent substrate 110 and the second transparent substrate 120 may be a curved plate having a light-transmitting property, for example, inorganic glass or organic glass, the inorganic glass may be soda-lime-silica glass, aluminosilicate glass, lithium-aluminosilicate glass, or borosilicate glass, and the organic glass may be Polycarbonate (PC) glass, polymethyl methacrylate (PMMA) glass, or the like. The first transparent substrate 110 and the second transparent substrate 120 may be transparent, or may be colored and have a light-transmitting property. The material of the first transparent substrate 110 and the material of the second transparent substrate 120 may be the same or different.

The light transmitting region R20 is a region of the laminated glass 10 through which visible light can pass, and in order to ensure driving safety after the laminated glass 10 is mounted on a vehicle, the visible light transmittance of the light transmitting region R20 is preferably 70% or more. The light blocking region R10 is a region where the visible light transmittance of the laminated glass 10 is low, and the light blocking regions R10 are distributed in the peripheral edge region of the laminated glass 10.

The adhesive film 130 is disposed between the first transparent substrate 110 and the second transparent substrate 120, and is used to adhere 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.

The light blocking region R10 includes a light blocking layer 140. the light blocking layer 140 may be a dark color ink layer disposed on the second surface 112 and/or the third surface 121 or a colored polymer film disposed between the second surface 112 and the third surface 121. The light-shielding layer 140 has a low transmittance of the projected light, and the light-shielding layer 140 is carried 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 may be formed on the light blocking region R10 by printing ink or the like. Optionally, the transmittance of the projected light of the light shielding layer 140 is less than or equal to 5%, and preferably less than or equal to 1%. Alternatively, the light shielding layer 140 may be a resin film with a dark color and low light transmittance, and of course, a resin film with a light color and low light transmittance may be used, and examples of the resin film may be bulk-colored PVB, PET, and the like.

In an embodiment, please continue to refer to fig. 3, fig. 3 is a cross-sectional layered structure diagram taken along line I-I of fig. 1 according to an embodiment of the present disclosure. The light shielding layer 140 is disposed on the second surface 112. In another embodiment, please refer to fig. 4, fig. 4 is a cross-sectional layered structure diagram of another embodiment of the present application along the line I-I in fig. 1. The light-shielding layer 140 is disposed on the third surface 121.

Specifically, on the one hand, if the light shielding layer 140 is not included in the laminated glass 10, the projection light of the projection device in the vehicle, which projects the first image P1 to the laminated glass 10, is incident on the laminated glass 10 from the fourth surface 122, and is reflected by the first surface 111 of the first transparent substrate 110, so as to form the reflected light a. Accordingly, 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, and for convenience of description, the projection light reflected by the fourth surface 122 is named as reflected light B. The reflected light B forms a main image visible to human eyes, the reflected light A forms an auxiliary image visible to human eyes, and a certain offset distance is reserved between the auxiliary image and the main image, namely a ghost phenomenon is generated. The laminated glass 10 according to the embodiment of the present application, which includes the light shielding layer 140, can reduce or even block the reflected light a, thereby weakening or even blocking a double image generated by the reflected light a and the reflected light B. Meanwhile, since the projection light transmittance of the light shielding layer 140 is low, the light shielding layer 140 can be used as a display background of the main image, so that the recognition degree of the main image and the contrast with the ambient brightness are improved, and the display quality of the main image can be remarkably improved.

An application scenario of the laminated glass 10 is described below. When the laminated glass 10 is applied to a vehicle 1, the laminated glass 10 is mounted on the vehicle 1 at a certain inclination angle as a front windshield. The first transparent substrate 110 in the laminated glass 10 is a substrate of the laminated glass 10 exposed outside the vehicle, and the second transparent substrate 120 is a substrate of the laminated glass 10 inside the vehicle. In order to explain the advantageous effects when the laminated glass 10 includes the light-shielding layer 140, a case where the light-shielding layer 140 is not included in the laminated glass 10 will be described. A projection device in the vehicle projects a first image P1 to 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. Light rays projected by a projection device in the vehicle from the first image P1 to the laminated glass 10 are incident on the laminated glass 10 from the fourth surface 122 and are reflected by the fourth surface 122 and the first surface 111, respectively, to form reflected light B and reflected light a, which are not overlapped to generate a reflected double image. The incident light C, which is formed by the light of the object outside the vehicle entering the laminated glass 10 from the first surface 111 and penetrating the laminated glass 10 into the vehicle, generates a transmission double image due to the oblique installation and the parallel thickness of the laminated glass 10. The inclusion of the light-shielding layer 140 in the laminated glass 10 according to the embodiment of the present application can reduce or even block the reflected light a and the incident light C, thereby weakening or even blocking the reflection ghost and the transmission ghost.

In summary, the laminated glass 10 provided by the embodiment of the present application has the light shielding layer 140 located in the light blocking region R10, so as to reduce or even block reflection double images and transmission double images. Therefore, the laminated glass 10 provided by the embodiment of the present application can enable the quality of the image projected thereon to be higher.

Referring to fig. 1 again, the light blocking region R10 includes a first region R110, the first region R110 is located at the bottom of the light transmissive region R20, and the first region R110 has one or more first functional display regions R111 for displaying a first image P1; a second region R120, the second region R120 being located at the top of the light-transmitting region R20; and a third region R130, the third region R130 is located at a side of the light-transmitting region R20, and the second region R120 and the third region R130 are used for shielding an electronic device or a trace.

It should be noted that the light blocking region R10 is disposed around the light transmissive region R20, that is, the first region R110, the second region R120, and the third region R130 are located in the light blocking region R10 and surround the light transmissive region R20.

In this embodiment, the light blocking region R10 is divided into three regions, the first region R110 is provided with one or more first function display regions R111, when the first region R110 is provided with a plurality of first function display regions R111, the plurality of first function display regions R111 may be separately provided, or integrally provided, or partially separately provided and partially integrally provided, and each of the first function display regions R111 is correspondingly used for displaying one of the first images P1. Optionally, the total area of the first functional display region R111 occupies more than 10% of the first region R110, so as 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 wires installed in a later application.

Please refer to fig. 4 again. In one embodiment, the first functional display region R111 is the fourth surface 112, the incident projection light includes 60% to 100% of 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%.

For example, when the proportion of the S-polarized light in the light projected from the second transparent substrate 120 side is relatively large, such as 60% to 100%, the reflectivity of the light blocking region R10 of the second transparent substrate 120 side to the light projected from the second transparent substrate 120 side is relatively large, such as 22% when the light is incident at an incident angle of 60 °, and the preferred proportion of the S-polarized light is 100%, so as to further weaken or even block the reflected light of the first transparent substrate 110. The orthographic projection of the dielectric film 150 on the second transparent substrate 120 covers all the first functional display regions R111, so that the brightness and definition of the light reflected on the second transparent substrate 120 by the incident light on the second transparent substrate 120 side can be further improved.

The arrangement of the light shielding layer 140 weakens and even eliminates the above ghost; the provision of the dielectric film 150 further weakens or even eliminates the above ghost and weakens or even eliminates the ghost effect of the second functional display region R211. When the loading angle can be 60 °, the reflection of the light-transmitting dielectric film 150 to the projection light in the first functional display region R111 is tested, and the data are shown in the following two tables.

Table 1 reflection data of the first functional display area on the light blocking area for projection light of the laminated glass without the transparent dielectric film.

Light source type	Reflectivity of light
		Common light source	7.5％
P polarized light	0.3％
		S polarized light	13％

Table 2 reflection data of the projection light in the first functional display region of the laminated glass having different transparent dielectric films.

Transparent dielectric film type	Light source type	Reflectivity of light
			Anti-reflection film	Common light source	5.1％
P-polarized light reflecting film	P polarized light	11％
			S-polarized light reflecting film	S polarized light	22％

In table 1, when the light source type is a normal light source, the light emitted by the normal light source is an irregular set of innumerable polarized lights, so that it cannot be found which direction the light intensity is biased to when directly observing. Such light vibrating in all directions with the same intensity of light waves may also be called natural light. When the light source type is P polarized light, the P polarized light in the light emitted by the light source accounts for 60-100%. When the type of the light source is S-polarized light, the S-polarized light in the light emitted by the light source accounts for 60-100%. In table 2, please refer to the description of the light source types in table 1, which is not described herein. The antireflection film is the aforementioned dielectric film 150 with S-polarized light antireflection capability and low reflectivity (less than 6%); the P-polarized light reflecting film is the aforementioned dielectric film 150 having the P-polarized light reflecting ability; the S-polarized light reflecting film is the aforementioned dielectric film 150 having the S-polarized light reflecting ability. As can be seen from the test data of the above two tables, in one embodiment, in the first functional display region R111, after the first projection light source 170 is a normal light source and the antireflection film is installed, the reflectance of the projection of the first projection light source 170 on the first functional display region R111 by the fourth surface 122 is reduced 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 light reflection film is installed, the reflectivity of the fourth surface 122 for the projection of the first projection light source 170 on the first functional display area R111 is increased from 0.3% to 11%. In yet another embodiment, in the first functional display region R111, when the first projection light source 170 is S-polarized light and an S-polarized light reflection film is installed, the reflectivity of the fourth surface 122 for the projection of the first projection light source 170 on the first functional display region R111 is increased from 13% to 22%.

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

Optionally, the display distance of the first image P1 is 0.5m to 5m, and the first image P1 may be key information such as a driving speed, a mailbox oil volume, or an engine speed; alternatively, the second image P2 may be displayed at a distance of 7.5m or more, and the second image P2 may be a larger image display such as a route guidance, a speed reminder, or an obstacle reminder.

Although embodiments of the present application have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present application, and that such changes and modifications are also to be considered as within the scope of the present application.
