Compared with the traditional instrument panel display, the human eye's line of sight can leave the road surface less, which greatly improves driving safety. In order to effectively solve the ghosting problem, a laminated coating or film is applied on the glass surface close to the driver. However, this film layer is prone to contamination and difficult to clean, and there will also be wrinkling problems on the curved glass, affecting the customer experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the first object of the present invention is to provide a black-edge display glass, in which an opening or notch is provided on the inner glass plate. By canceling a part of the inner layer glass, the incident light directly enters the reflection surface of the functional reflection layer and is reflected into the human eye, reducing the multiple reflections and refractions of the light between the outer glass plate and the inner glass plate layer, preventing them from being reflected or scattered again, thereby reducing the ghosting phenomenon.

[0004] The second object of the present invention is to provide a black-edge display system.

[0005] The third object of the present invention is to provide a vehicle.

[0006] To solve the above problems, an embodiment of the first aspect of the present invention provides a black-edge display glass, which includes an outer glass plate, an inner glass plate, an adhesive layer and a functional reflection layer.

[0041] An embodiment of the present application provides a vehicle 1000.

[0042] The vehicle 1000 includes a vehicle body 300 and a black-edge display system 100. The black-edge display system 100 includes a black-edge display glass 10 and a projection device 200. The black-edge display glass 10 is installed at the opening of the vehicle body 300. The black-edge display glass 10 divides the vehicle body 300 into the outside and the inside of the vehicle body 300. The projection device 200 is installed inside the vehicle body 300. The projection device 110 is used to emit projection light 701. The projection light 701 contains at least 70% of P-polarized light or contains at least 70% of S-polarized light. The projection light 701 is incident on the black-edge display glass 100. The black-edge display glass 100 reflects the projection light 702 into the eyes 6 of the driver and passengers to form a projection image, so that the driver and passengers can observe the projection image without significantly lowering their heads. As a result, the line of sight of the eyes 6 of the driver and passengers can leave the road surface less, maintaining more attention on the road surface or nearby, which is beneficial to observing the real-time situation outside the vehicle 300, and can more easily obtain necessary information for assisted driving such as driving information and entertainment information, thereby greatly improving driving safety. The image displayed by the black-edge display glass 100 provided in this embodiment can provide comprehensive and real-time driving information, and can partially replace or even completely replace the traditional instrument panel in terms of function. In some application scenarios, the traditional instrument panel can even be cancelled, thereby saving the interior space of the vehicle and optimizing the layout of the cockpit. The black-edge display system 100 can provide clear and intuitive display information without interfering with the normal driving line of sight of the driver and passengers, further optimizing the driving experience.

[0043] Among them, in the design of the black-edge display glass 10, the light source of the projection device 5 mainly contains P-polarized light. This design is to be compatible with polarized sunglasses to ensure that the driver and passengers can still clearly see the displayed image when wearing polarized sunglasses. P-polarized light refers to the light whose polarization direction is parallel to the incident plane. Polarized sunglasses usually filter out S-polarized light (the light whose polarization direction is perpendicular to the incident plane) and allow P-polarized light to pass through. Therefore, the display light source mainly containing P-polarized light can ensure that the displayed image is still clearly visible under polarized sunglasses; the projection device 5 is a TFT-LCD, Mini-LED, Micro-led, DLP, LCOS, LBS, or the like.

[0044] In this embodiment, the vehicle 300 is a sedan. In other embodiments, the vehicle 300 can also be a multi-Purpose Vehicle (MPV), a Sport / Suburban Utility Vehicle (SUV), an Off-Road Vehicle (ORV), a pickup truck, a minivan, a bus, a truck, or the like. The black-edge display glass 100 can be used as the front windshield, rear windshield, side window glass, or corner window glass of the vehicle 300. The following description will be made taking the black-edge display glass 100 as the front windshield as an example.

[0045] See Figure 1 , the black-edge display glass includes an outer glass plate 201, an inner glass plate 202, an adhesive layer 3, and a functional reflection layer 4. The outer glass plate 201 includes a first surface and a second surface arranged opposite to each other. The inner glass plate 202 includes a third surface and a fourth surface arranged opposite to each other. The adhesive layer 3 is connected between the second surface and the third surface; the functional reflection layer 4 is provided between the outer glass plate 201 and the inner glass plate 202; the inner glass plate 202 is provided with an opening or a notch.

[0046] Among them, the first surface is the outer surface of the outer glass plate 201, which is directly exposed to the external environment and has good scratch resistance and weather resistance; the second surface is the inner surface of the outer glass plate 201, which is in contact with the adhesive layer 3 and is used to connect with the inner glass plate 202; the third surface is the outer surface of the inner glass plate 202, which is in contact with the adhesive layer 3 and is used to connect with the outer glass plate 201; the fourth surface is the inner surface of the inner glass plate 202, which is usually the inner side of the glass and can be specially treated according to needs, such as anti-reflection coating or anti-glare treatment; the adhesive layer 3 is located between the second surface of the outer glass plate 201 and the third surface of the inner glass plate 202 and is used to firmly connect the outer glass plate 201 and the inner glass plate 202 together. The adhesive layer 3 is usually made of a transparent polymer material and has good adhesion and optical transparency to ensure the overall strength and transparency of the glass; the functional reflection layer 4 is arranged between the outer glass plate 201 and the inner glass plate 202 and is used to reflect light of a specific wavelength (such as projection light), thereby realizing the display function. The functional reflection layer 4 can be made of a variety of materials, such as metal oxides, nanomaterials or other thin film materials with high reflectivity. The design of the functional reflection layer 4 can ensure that light is effectively reflected within a specific angle and wavelength range, while allowing light of other wavelengths to pass through to maintain the transparency of the glass; an opening or notch is provided on the inner glass plate 202. Equivalent to removing a part of the inner layer of glass, the incident light 701 directly enters the reflection surface of the functional reflection layer 4 and is reflected to the human eye 6. The light passing through the functional reflection layer 4 continues to propagate to the shielding layer 203, and the shielding layer 203 absorbs these lights to prevent them from being reflected or scattered again, thereby reducing the ghosting phenomenon, reducing the multiple reflections and refractions of light between the glass layers, forming a clear display image, and further reducing the possibility of ghosting. At the same time, the structure is simplified, and the manufacturing cost and overall weight are reduced; the functional reflection layer 4 uses a material with a high reflectivity, such as metal oxide or nanomaterial, to ensure that light can be efficiently reflected, and is designed as a thin film structure to reduce the absorption and scattering of light. The reflectivity of the ordinary glass surface to P-polarized light is relatively low, usually not enough to achieve a clear display effect. Therefore, it is necessary to integrate the functional reflection layer 4 (P-light reflection film) on the glass surface to improve the reflectivity of P-polarized light. The adhesive layer 3 uses a transparent polymer material with good adhesion and optical transparency to ensure a firm connection between the outer glass plate 201 and the functional reflection layer 4. The thickness is moderate to reduce the propagation loss of light in the adhesive layer 3. It should be noted here that the opening is a through hole penetrating the glass; the notch is a groove, the opening of which is close to the driver, and the side away from the driver is a thinning area, and the glass thickness of the thinning area ≤ 1.0 mm, which can also achieve the effect of reducing ghosting.

[0047] See Figure 1 and Figure 2, the adhesive layer 3 includes a first adhesive layer 301 and a second adhesive layer 302. The functional reflective layer 4 is disposed between the first adhesive layer 301 and the second adhesive layer 302. The first adhesive layer 301 is located between the functional reflective layer 4 and the second surface, and the second adhesive layer 302 is located between the functional reflective layer 4 and the third surface.

[0048] Among them, the first adhesive layer 301 is located between the second surface of the outer glass plate 201 and the functional reflective layer 4, and is used to firmly connect the outer glass plate 201 and the functional reflective layer 4 together. The first adhesive layer 301 is usually made of a transparent polymer material, such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA), and has good adhesion and optical transparency to ensure the overall strength and transparency of the glass. The second adhesive layer 302 is located between the functional reflective layer 4 and the third surface of the inner glass plate 202, and is used to firmly connect the functional reflective layer 4 and the inner glass plate 202 together. The second adhesive layer 302 is also made of a transparent polymer material, such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA), and has good adhesion and optical transparency. The use of the first adhesive layer 301 and the second adhesive layer 302 ensures a firm connection between the outer glass plate 201, the functional reflective layer 4 and the inner glass plate 202, enhancing the stability and durability of the entire glass structure. The design of the transparent adhesive layer 3 material and the functional reflective layer 4 ensures efficient transmission and reflection of light, while maintaining the transparency of the glass and optimizing the optical performance.

[0049] See Figure 1 and Figure 2 , the functional reflective layer 4 has a P-light reflectivity Rp, and the P-light reflectivity Rp ≥ 10%.

[0050] Among them, the P-light reflectivity (Rp) of the functional reflective layer 4 refers to the reflection ability of this reflective layer to light (P-light) with a polarization direction parallel to the incident plane. The P-light reflectivity is an important parameter to measure the optical performance of the functional reflective layer 4, and it directly affects the brightness and contrast of the displayed image. In the present invention, the P-light reflectivity (Rp) of the functional reflective layer 4 is designed to meet the following conditions: Rp ≥ 10%; this reflectivity level ensures that the functional reflective layer 4 can effectively reflect the incident projection light, thereby forming a clear and bright displayed image on the glass surface. At the same time, the higher reflectivity helps to improve the visibility of the display effect, especially in a relatively dark environment.

[0051] See Figure 1 and Figure 2 , the functional reflective layer 4 has an S-light reflectivity Rs, and the S-light reflectivity Rs ≥ 30%.

[0052] Among them, when the traditional reflective layer processes specific polarized light (such as S light), the reflectivity may be relatively low, affecting the display effect. The functional reflective layer 4 of the present invention has an S light reflectivity Rs, and the S light reflectivity Rs≥30%. This design can significantly improve the reflection efficiency of the display device when processing S light, thereby improving the display quality and energy efficiency.

[0053] See Figure 3 , the black-edge display glass has a light-transmitting area 101 and a shielding area 102, and the functional reflective layer 4 is disposed in the shielding area 102; at least one display area is provided in the shielding area 102, and the opening or notch corresponds to the display area, and the opening or notch at least covers part of the display area.

[0054] Among them, the light-transmitting area 101 is the main part of the glass, which is used to maintain the transparency of the glass, allow light to pass through, and ensure that the driver and passengers can clearly see the road conditions outside the vehicle. The light-transmitting area 101 usually does not contain any display functions, and its main role is to provide a good view. The shielding area 102 is a specific area of the glass, which is used to implement the display function. The shielding area 102 is usually located at the edge or a specific position of the glass to avoid interfering with the normal vision of the driver and passengers. The shielding area 102 realizes the display function by setting the functional reflective layer 4, and at the same time reduces the scattering and reflection of light through the shielding layer 203 to ensure the clarity and contrast of the displayed image. The functional reflective layer 4 is disposed in the shielding area 102 and is used to reflect light of a specific wavelength (such as projection light), thereby realizing the display function. At least one display area is provided in the shielding area 102, which is used to display specific information, such as speed, navigation instructions, warning information, etc. The position and size of the display area can be designed according to specific application requirements to ensure the visibility and readability of the displayed information. The opening or notch at least covers part of the display area to ensure that the display device can project light onto the functional reflective layer 4, thereby forming a display image on the glass surface. The design of the opening or notch can be customized according to the shape and size of the display device to achieve the best display effect. The number and position of the display areas can be designed according to specific application requirements to ensure the visibility and readability of the displayed information.

[0055] See Figure 3 , the shielding area 102 includes a bottom shielding area located below the perspective area, and the display area is located in the bottom shielding area.

[0056] Among them, the shielding area 102 of the black-edge display glass can be further divided into multiple areas according to its position and function, and an important area is the bottom shielding area; the bottom shielding area is located below the light-transmitting area 101, usually at the bottom edge part of the glass. It is used to implement the display function while avoiding interfering with the normal vision of the driver and passengers. Due to its low position, the bottom shielding area 102 can be used to display some information that does not need to be frequently viewed, such as vehicle status information, assisted driving information, etc.

[0057] See Figure 2 and Figure 3 ,the black-edge display glass further includes a shielding layer 203 disposed within the shielding area 102, the shielding layer 203 being located between the outer glass plate 201 and the functional reflection layer 4, and the material of the shielding layer 203 being selected from at least one of dark ink, opaque polymer film, and dimming film.

[0058] Among them, the shielding layer 203 is an important component of the black-edge display glass, and its position and function are crucial for realizing the display function and optimizing the optical performance; the shielding layer 203 is disposed within the shielding area 102 and is located between the outer glass plate 201 and the functional reflection layer 4. This design ensures that the shielding layer 203 can effectively absorb or block the light passing through the functional reflection layer 4, reducing the ghosting phenomenon, while not affecting the reflection performance of the functional reflection layer 4; the shielding layer 203 can provide additional protection to prevent the functional reflection layer 4 from being affected by the external environment, such as scratches, corrosion, etc., and extend its service life. Dark ink has a high absorption rate and can effectively absorb light, reducing light reflection and scattering. It is suitable for scenarios that require high-contrast displays, such as the shielding area 102 of automotive windshields. It has a low cost, is easy to process, and can provide good optical performance. The dimming film can adjust its light transmittance through external control (such as voltage or current), thereby achieving a dynamic shielding effect. It is suitable for scenarios that require dynamic adjustment of the display effect, such as intelligent automotive windshields. It can dynamically adjust the light transmittance according to the ambient light and user needs, providing a flexible display effect. The opaque polymer film has good optical opacity and mechanical properties and can effectively block the transmission of light. It is suitable for scenarios that require high shielding performance, such as the shielding area 102 of mechanical parts. It has good mechanical properties and durability and can provide a stable shielding effect.

[0059] See Figure 1 ,the functional reflection layer 4 extends more than 1 mm beyond the display area on all sides.

[0060] Among them, in the design of the black-edge display glass, the size of the functional reflection layer 4 is specifically adjusted relative to the display area to ensure the optimization of the display effect and the stability of the structure. The functional reflection layer 4 extends more than 1 mm beyond the display area on all sides. This design ensures that the functional reflection layer 4 can completely cover the display area and form an edge area of more than 1 mm around the display area. The edge area of more than 1 mm can reduce the scattering and reflection of light at the edge of the display area, ensuring the clarity and contrast of the displayed image. The edge area can provide additional mechanical support to ensure a firm connection between the functional reflection layer 4 and the display area. The edge area can prevent light from leaking from the edge of the display area, further reducing the ghosting phenomenon.

[0061] See Figure 2, the second adhesive layer 302 is provided with an opening relative to the display area.

[0062] Among them, the second adhesive layer 302 is provided with an opening relative to the display area, that is, there is no adhesive layer on the surface of the functional reflection layer 4 close to the inner surface of the vehicle; the opening can be formed in the inner adhesive layer by processes such as laser cutting, machining or chemical etching to ensure that the edge of the opening is smooth and free of burrs; the size of the opening should be slightly larger than the size of the display area to ensure that the light can completely cover the display area. For example, the size of the opening can be 1-2 mm larger than the size of the display area, and the specific size should be adjusted according to the light distribution of the display device and the actual requirements of the display area; by reducing the scattering and absorption of light by the adhesive layer, the opening design ensures that the light can directly reach the functional reflection layer 4, thereby optimizing the display effect and improving the clarity and contrast of the displayed image; the opening design reduces the material usage of the adhesive layer and further realizes the lightweight of the glass structure.

[0063] See Figure 3 , the visible light transmittance of the shielding area 102 is less than or equal to 0.1%.

[0064] Among them, the visible light transmittance of the shielding area 102 is less than or equal to 0.1%. This requirement ensures that the shielding area 102 can effectively block most visible light, reduce the light transmission, thereby optimizing the display effect, reducing background interference, and enhancing the contrast and clarity of the displayed image. The low visible light transmittance ensures that the shielding area 102 can effectively block the background light, reduce the scattering and reflection of light, thereby enhancing the contrast and clarity of the displayed image. This design makes the displayed image clearer and brighter, especially in a strong light environment, and can significantly improve the display effect. The low visible light transmittance reduces the interference of the background light on the displayed image, enabling the driver and passengers to focus more on the displayed information and reducing visual fatigue. This is crucial for driving safety and user experience, especially in a complex driving environment.

[0065] See Figure 4 , the distance between the upper edge of the functional reflection layer 4 and the upper edge of the inner glass plate notch is D1, the distance between the lower edge of the functional reflection layer 4 and the lower edge of the inner glass plate notch is D2, the distance between the left edge of the functional reflection layer 4 and the left edge of the inner glass plate notch is D3, the distance between the right edge of the functional reflection layer 4 and the right edge of the inner glass plate notch is D4, D1≥1mm; D2≥1mm; D3≥1mm; D4≥1mm.

[0066] Among them, in the design of the black-edge display glass, the edge distance between the functional reflective layer 4 and the inner glass notch is an important design parameter, which directly affects the display effect and structural stability. The edge distance ensures sufficient space between the functional reflective layer 4 and the notch, reducing light scattering and reflection in the edge area, thereby optimizing the display effect and improving the clarity and contrast of the displayed image. The design of the edge distance can also reduce the ghosting phenomenon and further enhance the display effect. The edge distance provides additional mechanical support to ensure that the functional reflective layer 4 does not come into contact with or rub against the notch during use, thereby extending its service life. The design of the edge distance can also reduce the risk of deformation or damage to the functional reflective layer 4 caused by thermal expansion or mechanical stress. The design of the edge distance takes into account the feasibility of the manufacturing process to ensure accurate positioning and assembly during production, improving production efficiency and product quality.

[0067] The following will illustrate the specific structure of the black-edge display system 100 with two specific embodiments as examples.

[0068] See Figure 5 , an inner glass plate 202 has a notch; a second adhesive layer 302 is disposed in the notch of the inner glass plate 202 and is encapsulated with the side edge of the notch of the inner glass plate 202 by means of overflow glue, wherein the height of the overflow glue is not higher than the thickness of the inner glass plate 202. The overflow glue portion of the second adhesive layer 302 forms a sealing edge to ensure the airtightness of the encapsulation. The notch depth of the inner glass plate 202 matches the thickness of the second adhesive layer 302 to ensure uniform distribution of the overflow glue portion. The material of the second adhesive layer 302 has good weather resistance and anti-aging performance to extend the service life of the encapsulation structure.

[0069] See Figure 6 , the notch of the black-edge display glass 100 is an inverted U-shaped notch, that is, the lower edge of the glass is an open notch; the inverted U-shaped notch is a special notch design, and its shape is similar to the inverted letter "U". In this design, the lower edge of the notch is open and there is no closed bottom.

[0070] See Figure 7, the P-polarized reflective film is only integrated in the driver's display area. The P-polarized reflective film is used to reflect P-polarized light to ensure that the driver's display screen can clearly display key driving information, such as speed, navigation instructions, warning messages, etc. Only the inner glass 202 corresponding to the driver's display area is grooved to display key information for the driver and passengers; the P-polarized reflective film can be in the form of a coating or a film. The coating deposits a high-reflectivity thin film on the glass surface through vacuum coating technology; the film attaches the reflective film to the glass surface through a film pasting process. The design of the co-pilot entertainment screen display area focuses on providing entertainment content to ensure the comfort of passengers. The following are the specific design features of the co-pilot entertainment screen display area: No reflective film is set: Design choice: The P-polarized reflective film is not set in the co-pilot entertainment screen display area to reduce optical interference and improve the display effect. Display type: The co-pilot entertainment screen is an S-polarized screen, mainly displaying entertainment content, such as videos, music, etc. Display content: It includes multimedia content, games, etc. to ensure the entertainment experience of passengers.
