[0002] With the development of intelligent vehicles, vehicle windows can be used as image display elements, allowing drivers to obtain key information such as road conditions and vehicle status without having to significantly shift their gaze, greatly improving driving safety. Examples include windshield head-up display systems (W-HUD) and augmented reality head-up display systems (AR-HUD) installed on traditional vehicles.

[0062] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0063] And / or: It is just a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0064] Multiple: refers to two or more than two.

[0065] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either directly connected or indirectly connected through an intermediary.

[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. It should be noted that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] Embodiments of the present application provide a black-bordered display glass, a design method for black-bordered display glass, and a vehicle.

[0068] See also Figure 1 , Figure 1 It is a structural schematic diagram of a vehicle 200 provided in an embodiment of the present application.

[0069] For ease of description, a coordinate system is established with the length of the vehicle 200 as the X-axis, the width of the vehicle 200 as the Y-axis, and the height of the vehicle 200 as the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. Figure 1 The shaded surface shown is the XZ plane. The XZ plane is the vertical plane on which the central axis of vehicle 200 lies. The central axis of vehicle 200 extends from the front to the rear of vehicle 200 and runs through the center of vehicle 200. It is parallel to the direction of travel of vehicle 200 and is generally located at the geometric center of vehicle 200, dividing vehicle 200 into two symmetrical parts.

[0070] The X-axis includes a positive X-axis direction and a negative X-axis direction, the Y-axis includes a positive Y-axis direction and a negative Y-axis direction, and the Z-axis includes a positive Z-axis direction and a negative Z-axis direction. In the diagram, the backward direction of vehicle 200 is the positive X-axis direction, and the forward direction of vehicle 200 is the negative X-axis direction. The direction from the passenger seat to the driver's seat is the positive Y-axis direction, and the direction from the driver's seat to the passenger seat is the negative Y-axis direction. The direction from the ground to the top of vehicle 200 is the positive Z-axis direction, and the direction from the top of vehicle 200 to the ground is the negative Z-axis direction.

[0071] The vehicle 200 may include a vehicle body 210 and a black-bordered display glass 100. The black-bordered display glass 100 is fixedly connected to the vehicle body 210. The vehicle body 210 may include a hood 211. The hood 211 is tilted relative to the black-bordered display glass 100. The hood 211 may include a first front edge 211a and a first rear edge 211b. The first rear edge 211b and the first front edge 211a are arranged opposite each other in the longitudinal direction of the vehicle 200 (the X direction in the figure). The first front edge 211a is the end of the hood 211 farthest from the black-bordered display glass 100. The first rear edge 211b is the end of the hood 211 closest to the black-bordered display glass 100.

[0072] It should be noted that Figure 1 The purpose of the diagram is merely to schematically illustrate the connection between the black-bordered display glass 100 and the hood 211, and is not intended to limit the connection locations, specific structures, or quantities of the various devices. In other embodiments of the present application, the vehicle 200 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0073] In recent years, head-up display (HUD) devices have been widely used in vehicles, allowing drivers to obtain key information such as road information and vehicle status without having to move their sight significantly, greatly improving driving safety. For example, the windshield head-up display system (W-HUD) and augmented reality head-up display system (AR-HUD) configured on traditional vehicles. Regardless of W-HUD or AR-HUD, the HUD image is displayed in the light-transmitting area of the windshield, which is easily affected by the light in the driving environment. Especially in strong sunlight, the contrast between the HUD image and the display background is significantly reduced, which greatly reduces the clarity of the HUD image. Unlike the related art, the present application provides a black-bordered display glass, which sets the image display area in the bottom shielding area of the black-bordered display glass, that is, the bottom shielding area is used as the display background for the image display. This not only enables the driver to obtain key information such as road information and vehicle status without having to move his sight significantly, greatly improving driving safety, but also prevents the displayed image from being interfered with by ambient light, and can greatly improve the contrast between the displayed image and the display background. In particular, a through-type panoramic display effect can be designed to display images from A-pillar to A-pillar, thereby realizing a panoramic head-up display (PHUD).

[0074] However, the bottom shielding area of traditional car windshields is too small in the Z-axis direction, typically less than 100mm, or even less than 50mm. This clearly fails to meet the image display size requirements, making the displayed image difficult for the driver to observe, which can pose a driving safety hazard. While setting the bottom shielding area width (i.e., the distance between the upper and lower boundaries of the black border area) based directly on the size of the imaging area can meet imaging requirements, it fails to consider the visibility between the driver's field of view and the hood. This can cause the black border area to obstruct the driver's view of the hood, further affecting the driver's accurate perception of the vehicle's position, especially during low-speed parking, increasing driving risks.

[0075] Thus, the embodiments of the present application provide a black-bordered display glass 100 and a design method for black-bordered display glass 100 that meet ergonomic principles. The size of the bottom shielding area is determined based on the hood position and the driver's eye position information, ensuring that the bottom shielding area meets the size requirements for image display. This prevents the bottom shielding area from obstructing the driver's view of the hood, thereby preventing the bottom shielding area from interfering with the driver's accurate perception of the vehicle's position. This allows the driver to accurately identify the vehicle's position on the road, reducing driving risks. Furthermore, the size of the bottom shielding area fully considers the adaptability and comfort of the driver's eye position, preventing the driver from experiencing visual fatigue when simultaneously observing the image display information and the road surface.

[0076] The structure of the black-border display glass 100 will be described below.

[0077] See also Figure 2 , Figure 2 This is a structural diagram of the black-bordered display glass 100 provided in an embodiment of the present application. For the convenience of illustration, the dotted line is used as the boundary, the shadowed area is the shielding area 20, the area surrounded by the shadow is the light-transmitting area 10, and the area within the shielding area 20 with a different shadow from the shielding area 20 is the image display area 30. However, it should be noted that Figure 2 The division of the light-transmitting area 10 , the shielding area 20 and the image display area 30 is merely an example, and does not represent the actual sizes of the light-transmitting area 10 , the shielding area 20 and the image display area 30 .

[0078] The black-bordered display glass 100 has a light-transmitting area 10, a shielding area 20, and at least one image display area 30. The visible light transmittance of the light-transmitting area 10 is greater than or equal to 70%, and the visible light transmittance of the shielding area 20 is less than or equal to 5%. The light-transmitting area 10 is located in the center of the black-bordered display glass 100 and can be used to provide a field of view for the driver and passengers in the vehicle, ensuring driving safety. The shielding area 20 surrounds and is connected to the periphery of the light-transmitting area 10 and can be used for shielding, protection, and enhancing the overall aesthetics. Preferably, the visible light transmittance of the shielding area 20 is less than or equal to 3%, more preferably less than or equal to 1%, further less than or equal to 0.5%, further less than or equal to 0.05%, or even almost equal to 0, that is, it is opaque.

[0079] The shielding area 20 includes a bottom shielding area 21, a top shielding area 22, a left shielding area 23, and a right shielding area 24. The top shielding area 22 and the bottom shielding area 21 are respectively located on opposite sides of the light-transmitting area 10. The bottom shielding area 21 is located below the light-transmitting area 10, that is, on the negative Z-axis side of the light-transmitting area 10. The top shielding area 22 is located above the light-transmitting area 10, that is, on the positive Z-axis side of the light-transmitting area 10. The left shielding area 23 and the right shielding area 24 are also respectively located on opposite sides of the light-transmitting area 10. The left shielding area 23 is located on the left side of the light-transmitting area 10, that is, on the positive Y-axis side of the light-transmitting area 10. The right shielding area 24 is located on the right side of the light-transmitting area 10, that is, on the negative Y-axis side of the light-transmitting area 10. The bottom shielding area 21 , the left shielding area 23 , the top shielding area 22 and the right shielding area 24 are connected end to end, surround the outer periphery of the light-transmitting area 10 , and form the shielding area 20 .

[0087] The black border display glass 100 may further include a shielding layer 60. The shielding layer 60 is connected to the laminated glass 40 and is disposed around the circumference of the laminated glass 40. The shielding layer 60 is located between the outer glass 41 and the inner glass 43. Alternatively, the shielding layer 60 is located on the side of the inner glass 43 facing away from the outer glass 41. Specifically, Figure 3a As shown, the shielding layer 60 can be connected to the second surface 412 of the outer glass 41. Alternatively, as shown in FIG. Figure 3b As shown, the shielding layer 60 can be connected to the third surface 431 of the inner glass 43. Alternatively, as shown in FIG. Figure 3c As shown, the shielding layer 60 may be connected to the fourth surface 432 of the inner glass 43 .

[0088] Please continue to refer to Figure 3a 、 Figure 3b and Figure 3c The area where the shielding layer 60 is located can form a shielding area 20. Since the shielding layer 60 is typically formed using black ink, those skilled in the art also generally refer to the shielding area 20 as the black-bordered area. The area outside the shielding layer 60 can form a light-transmitting area 10. The shielding layer 60 can be used to shield the edges of the black-bordered display glass 100 and the internal heating structure, thereby enhancing the aesthetics of the vehicle 200. It can also block ultraviolet rays and prevent aging of materials within the vehicle.

[0089] The projection of the shielding layer 60 in the bottom shielding area 21 onto the fourth surface 432 along the thickness direction of the laminated glass 40 (i.e., the thickness direction of the black-bordered display glass 100) covers the image display area 30. In other words, the image display area 30 is located within the projection of the shielding layer 60 in the bottom shielding area 21 onto the fourth surface 432 along the thickness direction of the black-bordered display glass 100. In the embodiment of the present application, the shielding layer 60 in the bottom shielding area 21 can also serve as a display background for the displayed image.

[0090] The shielding layer 60 can be a dark ink layer, an opaque polymer film, or a dimming film. The dark ink layer can be formed by printing ceramic ink or UV ink using a process such as screen printing or inkjet printing, followed by curing or high-temperature sintering. The opaque polymer film can be a body-colored polymer film, for example, by adding a black or brown coloring component during the polymer film manufacturing process; it can also be a polymer film with ink or pigment printed on the surface, for example, by printing black ink or brown pigment on the surface of the polymer film; it can also be a dyed or colored polymer film, for example, by coloring the polymer film with a black or brown dye; the material of the polymer film can be polyvinyl butyral (PVB), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. Preferably, the thickness of the opaque polymer film is less than or equal to 0.3 mm, and specific examples include 0.3 mm, 0.25 mm, 0.2 mm, 0.15 mm, 0.1 mm, 0.08 mm, 0.05 mm, 0.02 mm, etc., so that the opaque polymer film has a smaller impact on the overall thickness of the laminated glass structure. It is more preferably less than or equal to 0.1 mm, and even more preferably less than or equal to 0.05 mm. The dimming film can be a polymer dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a dye liquid crystal film (LC), etc. The minimum visible light transmittance of the dimming film is less than or equal to 5%, for example, 3%, 2%, 1%, 0.5%, or 0%. In addition, the maximum visible light transmittance of the dimming film can be set as needed, for example, 10%, 20%, 30%, 50%, 70%, 80%, etc. For example, the visible light transmittance of the dimming film can be adjusted between 0% and 20%, between 0.5% and 50%, or between 0% and 70%. The dimming film can meet the visible light transmittance requirements in multiple scenarios. For example, when black-border display is required, the dimming film is in an opaque state (visible light transmittance is less than or equal to 5%, or even 0%) to improve the contrast between the displayed image and the display background. When no display is required, the dimming film is in a transparent state (visible light transmittance is greater than or equal to 70%) to achieve transparency in a larger area of the black-border display glass 100.

[0091] The shielding layer 60 may include a sub-shielding layer 61. The sub-shielding layer 61 is located within the bottom shielding region 21 of the black-bordered display glass 100 and extends along the width of the black-bordered display glass 100. The width of the black-bordered display glass 100 is parallel to the Y-axis. The sub-shielding layer 61 may include a bottom edge 611 and a top edge 612. The bottom edge 611 is the bottommost edge of the sub-shielding layer 61 in the Z-axis direction, and the top edge 612 is the topmost edge of the sub-shielding layer 61 in the Z-axis direction.

[0092] In the embodiment of the present application, the sub-shielding layer 61 is the shielding layer 60 located in the bottom shielding area 21. The sub-shielding layer 61 can be a single-layer structure, specifically provided on the second surface 412, or provided on the third surface 431, or provided on the fourth surface 432, or provided between the adhesive layer 42 and the second surface 412, or provided between the adhesive layer 42 and the third surface 431. The sub-shielding layer 61 can also be a double-layer structure or a multi-layer structure, for example, one layer provided on the second surface 412 and another layer provided on the third surface 431, or one layer provided on the second surface 412 and another layer provided on the fourth surface 432, or one layer provided on the second surface 412 and another layer provided between the adhesive layer 42 and the third surface 431, or one layer provided between the adhesive layer 42 and the second surface 412 and another layer provided on the third surface 431.

[0093] The image display area 30 is located in the bottom shielding area 21. The image display area 30 has a first reflectivity R1 for the projection light incident at an incident angle of 64° to 75°, and the first reflectivity R1 is ≥ 20%. The number of the image display area 30 can be one (e.g. Figure 2 As shown), there may also be multiple, such as two, three or more than four. The specific amount of image display areas 30 can be designed according to actual needs. When the number of image display areas 30 is multiple, the multiple image display areas 30 can be spaced apart in the width direction of the black-bordered display glass 100 (the Y-axis direction shown in the figure). Alternatively, the multiple image display areas 30 can also be spaced apart in the height direction of the black-bordered display glass 100 (the Z-direction shown in the figure). Alternatively, the multiple image display areas 30 can also be spaced apart in both the length direction and the width direction of the black-bordered display glass 100.

[0094] The image display area 30 may only cover a portion of the bottom shielding area 21, for example, at least 30% of the area, or at least 40% of the area, or at least 50% of the area, or at least 60% of the area, or at least 70% of the area, or at least 80% of the area, or at least 90% of the area of the bottom shielding area 21, or even the entire bottom shielding area 21 to form a through-type panoramic display effect from A-pillar to A-pillar.

[0095] In the embodiment of the present application, vehicle 200 further includes a projection device (not shown) that projects light onto image display area 30, where it is reflected and then enters the human eye, allowing the human eye to observe a clear, ghost-free display image located in front of black-bordered display glass 100. The displayed image can be used to provide information to the driver, such as road information such as navigation routes and traffic signs, vehicle status information such as speed, fuel level, and engine status, and entertainment information such as music and broadcasts.

[0096] In the embodiment of the present application, the wavelength of the projection light is within the range of 380nm to 780nm. The projection light may be incident on the image display area 30 at an incident angle of 67°, with the first reflectivity R1 ≥ 25%; or at an incident angle of 68°, with the first reflectivity R1 ≥ 26%; or at an incident angle of 69°, with the first reflectivity R1 ≥ 28%; or at an incident angle of 70°, with the first reflectivity R1 ≥ 30%.

[0097] The projection light may contain at least 80% S-polarized light and at most 20% P-polarized light. The image display area 30 primarily reflects S-polarized light to form a displayed image. The image display area 30 may utilize the fourth surface 432 of the inner glass 43 to directly reflect the S-polarized light for imaging, or utilize an S-polarized light enhancing reflective element added to the bottom shielding area 21 to reflect the S-polarized light for imaging. The reflectivity of the image display area 30 for S-polarized light in the incident projection light is S-light reflectivity Rs. Preferably, S-light reflectivity Rs ≥ 25%, or S-light reflectivity Rs ≥ 28%, or S-light reflectivity Rs ≥ 29%, or S-light reflectivity Rs ≥ 30%, or S-light reflectivity Rs ≥ 35%, or S-light reflectivity Rs ≥ 40%, or S-light reflectivity Rs ≥ 45%. The image display area 30 designed in the present application has a reflectivity Rs ≥ 25% for S-polarized light in the incident projection light, which can meet the requirements of high contrast and high definition for the displayed image while also meeting the need to reduce power consumption of the projection device. Furthermore, the projection light may contain at least 85% S-polarized light and at most 15% P-polarized light, or at least 90% S-polarized light and at most 10% P-polarized light, or at least 95% S-polarized light and at most 5% P-polarized light, or even almost 100% S-polarized light.

[0098] Among them, the projection light can contain at least 80% P-polarized light and at most 20% S-polarized light. The image display area 30 mainly reflects P-polarized light to form a display image. The image display area 30 can use the P-polarized light enhancement reflective element added in the bottom shielding area 21 to reflect P-polarized light for imaging. The reflectivity of the image display area 30 to the P-polarized light in the incident projection light is the P-light reflectivity Rp. Preferably, the P-light reflectivity Rp ≥ 20%, or the P-light reflectivity Rp ≥ 25%, or the P-light reflectivity Rp ≥ 30%, or the P-light reflectivity Rp ≥ 35%, P-light reflectivity Rp ≥ 40%, or the P-light reflectivity Rp ≥ 45%. The image display area 30 designed in the present application has a reflectivity Rs ≥ 20% for the P-polarized light in the incident projection light, which can not only meet the requirements of high contrast and high definition of the displayed image, but also meet the requirements of reducing the power consumption of the projection device, and can also meet the needs of the driver wearing polarized sunglasses (sunglasses) while driving. Furthermore, the projection light may contain at least 85% P-polarized light and at most 15% S-polarized light, or at least 90% P-polarized light and at most 10% S-polarized light, or at least 95% P-polarized light and at most 5% S-polarized light, or even almost 100% P-polarized light.

[0099] In order to prevent the bottom shielding area 21 from blocking the driver's field of view of the hood 211, the black-bordered display glass designed in the embodiment of the present application satisfies the following requirements: the line between the driver's reference eye point M and the top edge 612 of the sub-shielding layer 61 is a first line, the line between the driver's reference eye point M and the first front edge 211a of the hood 211 is a second line, and the angle between the second line and the Z axis is greater than or equal to the angle between the first line and the Z axis. Specifically, the driver's reference eye point M is first determined, and then a reference plane parallel to the XZ plane is drawn through the reference eye point M. The intersection of the reference plane and the top edge 612 of the sub-shielding layer 61 is the first intersection, and the line between the reference eye point M and the first intersection is the first line; the intersection of the reference plane and the first front edge 211a of the hood 211 is the second intersection, and the line between the reference eye point M and the second intersection is the first line.

[0100] In order to ensure that the driver can simultaneously observe the image display area 30 and the first front edge 211a of the hood 211 while also taking into account the overall aesthetics of the vehicle 200, the angle between the second connecting line and the Z-axis is preferably 0° to 1.5° greater than the angle between the first connecting line and the Z-axis. Specific examples include 0°, 0.1°, 0.2°, 0.3°, 0.4°, 0.5°, 0.6°, 0.7°, 0.8°, 0.9°, 1.0°, 1.1°, 1.2°, 1.3°, 1.4°, 1.5°, etc. When the angle between the second connecting line and the Z-axis is 0° greater than the angle between the first connecting line and the Z-axis, that is, the angle between the second connecting line and the Z-axis is equal to the angle between the first connecting line and the Z-axis, indicating that the first connecting line and the second connecting line coincide with each other. More preferably, the angle between the second line and the Z axis is 0.1° to 1° greater than the angle between the first line and the Z axis; further, the angle between the second line and the Z axis is 0.2° to 0.8° greater than the angle between the first line and the Z axis.

[0101] In the embodiment of the present application, the total length of the image display area 30 in the Y-axis direction is greater than or equal to 850 mm, which is more conducive to displaying more and richer information, allowing the driver to obtain more image display information. Preferably, the total length of the image display area 30 in the Y-axis direction is greater than or equal to 900 mm; more preferably, the total length of the image display area 30 in the Y-axis direction is greater than or equal to 1000 mm; further, the total length of the image display area 30 in the Y-axis direction is greater than or equal to 1100 mm; further, the total length of the image display area 30 in the Y-axis direction is greater than or equal to the length of the bottom shielding area 21 in the Y-axis direction. It is understood that when there is only one image display area 30, the total length of the image display area 30 in the Y-axis direction is the length of one image display area 30; when there are multiple image display areas 30, the total length of the image display area 30 in the Y-axis direction is the sum of the lengths of the multiple image display areas 30.

[0102] In the embodiment of the present application, to meet the requirement of a larger display size for the image display area 30, the distance between the top edge 612 and the bottom edge 611 of the sub-shielding layer 61 is greater than or equal to 150 mm. Specific examples include 150 mm, 160 mm, 180 mm, 200 mm, 220 mm, 240 mm, 250 mm, 260 mm, 280 mm, 300 mm, 320 mm, 340 mm, 350 mm, 360 mm, 380 mm, 400 mm, etc. Preferably, the distance between the top edge 612 and the bottom edge 611 of the sub-shielding layer 61 is 160 mm to 350 mm. More preferably, the distance between the top edge 612 and the bottom edge 611 of the sub-shielding layer 61 is 200 mm to 300 mm. This ensures that the driver can simultaneously observe the image display area 30 and the first front edge 211a of the hood 211, while also taking into account the overall aesthetics of the vehicle 200.

[0103] In the embodiment of the present application, the black-bordered display glass may further include a functional layer (not shown), which is disposed between the second surface 412 and the third surface 431. Specifically, the functional layer may be disposed on the second surface 412, or on the third surface 431, or between the second surface 412 and the adhesive layer 42, or within the adhesive layer 42, or between the adhesive layer 42 and the third surface 431.

[0104] Exemplarily, the functional layer may be a heat-insulating layer. The heat-insulating layer enables the black-edged display glass 100 to have excellent heat-insulating properties, thereby improving the thermal comfort of the vehicle interior environment. The total solar transmittance (TTS) of the black-edged display glass 100 with the heat-insulating layer is less than or equal to 55%, preferably less than or equal to 50%, or even less than or equal to 45%. The lower the total solar transmittance, the better the heat-insulating properties of the black-edged display glass 100. The material of the heat-insulating layer may be one or more of a single silver nanocoating, a double silver nanocoating, a triple silver nanocoating, a quadruple silver nanocoating, an ITO (Indium tin oxide) nanocoating, an FTO (fluorine-doped tin oxide) nanocoating, and an infrared blocking microcoating.

[0105] For example, the functional layer can be an electric heating element. The electric heating element includes a heating layer and at least two busbars, and the busbars are directly electrically connected to the heating layer. The heating layer can be a single silver electric heating coating, a double silver electric heating coating, a triple silver electric heating coating, a quadruple silver electric heating coating, a five silver electric heating coating, a TCO electric heating coating, a metal wire, a printed silver paste wire, a nano silver wire, a carbon fiber wire, a metal grid or a graphene heating sheet. The electric heating element can make the black-bordered display glass 100 have a power of at least 400W / m 2 Heating power density.

[0106] For example, the functional layer may be a dimming element, wherein the dimming element may be a polymer dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a dye liquid crystal film (LC), or the like.

[0107] For example, the functional layer may be an antenna element, which may be a V2X antenna, a 5G antenna, a GNSS antenna, a Bluetooth antenna, a WiFi antenna, an AM antenna, an FM antenna, etc., thereby enabling interaction between the vehicle's main control and the outside world, such as receiving radio broadcasts, 5G communications, V2X communications, and high-precision positioning services.

[0108] The embodiment of the present application also provides a design method for a black-bordered display glass 100 to prepare the black-bordered display glass 100. The structure and related description of the black-bordered display glass 100 involved in the design method can be found in Figure 1-Figure 3c The above description will not be repeated here. Figure 1-Figure 3c The black edge display glass 100 shown in FIG. is used as an example for further description. In the absence of conflict, these descriptions can be applied to Figure 1-Figure 3c Black border display glass 100 is shown.

[0109] Please refer to Figure 1-Figure 3c The design method of the black-border display glass 100 provided in the embodiment of the present application may at least include steps S100 and S200, which are described in detail as follows.

[0110] S100: providing a glass body 50.

[0111] S200: Based on the driver's eye position information, a shielding layer 60 is formed on the glass body 50 to prepare the black-bordered display glass 100. The shielding layer 60 is arranged in a circumferential direction of the glass body 50. The shielding layer 60 may include a sub-shielding layer 61. The sub-shielding layer 61 is located in the bottom shielding area 21 of the black-bordered display glass 100 and extends along the Y-axis direction of the black-bordered display glass 100. The sub-shielding layer 61 may include a bottom edge 611 and a top edge 612. The top edge 612 of the sub-shielding layer 61 and the first front edge 211a of the hood 211 are both located within the driver's field of view.

[0112] Each step will be further described below.

[0113] First, combine Figure 3a 、 Figure 3b and Figure 3c The above-mentioned step S100 will be described.

[0114] S100: providing a glass body 50.

[0115] The glass body 50 can be the outer glass 41. That is, the glass body 50 can serve as the outer glass 41 of the laminated glass 40 described above. Alternatively, the glass body 50 can be the inner glass 43. That is, the glass body 50 can serve as the inner glass 43 of the laminated glass 40 described above.

[0116] Then combine Figure 3a 、 Figure 3b and Figure 3c Let's describe the above step S200.

[0117] S200: Based on the driver's eye position information, a shielding layer 60 is formed on the glass body 50 to prepare a black-bordered display glass 100. The shielding layer 60 is arranged in a circumferential direction of the glass body 50. The shielding layer 60 may include a sub-shielding layer 61. The sub-shielding layer 61 is located in the bottom shielding area 21 of the black-bordered display glass 100 and extends along the width direction of the black-bordered display glass 100. The width direction of the black-bordered display glass 100 is parallel to the Y-axis direction. The sub-shielding layer 61 may include a bottom edge 611 and a top edge 612. The bottom edge 611 is the bottommost side of the sub-shielding layer 61 in the Z-axis direction, and the top edge 612 is the topmost side of the sub-shielding layer 61 in the Z-axis direction. The top edge 612 and the first front edge 211a of the hood 211 are both located within the driver's field of view.

[0118] In this step, when the glass body 50 is the outer glass 41 of the laminated glass 40, the shielding layer 60 can be connected to the second surface 412 of the outer glass 41. Under these conditions, the process of preparing the black-bordered display glass 100 can be roughly as follows: after forming the shielding layer 60 on the second surface 412 of the outer glass 41, the outer glass 41 with the shielding layer 60 is combined with the inner glass 43 to form the laminated glass 40. At this point, the shielding layer 60 is connected to the laminated glass 40 and, together with the laminated glass 40, forms the black-bordered display glass 100. For example, the shielding layer 60 can be applied to the second surface 412 of the outer glass 41 by printing.

[0119] Alternatively, when the glass body 50 is the inner glass 43 of the laminated glass 40, the shielding layer 60 can be connected to the third surface 431 of the inner glass 43. Under these conditions, the process for preparing the black-bordered display glass 100 can be roughly as follows: after forming the shielding layer 60 on the third surface 431 of the inner glass 43, the inner glass 43 with the shielding layer 60 is combined with the outer glass 41 to form the laminated glass 40. In this case, the shielding layer 60 is connected to the laminated glass 40 and, together with the laminated glass 40, forms the black-bordered display glass 100. For example, the shielding layer 60 can be applied to the third surface 431 of the inner glass 43 by printing.

[0120] Alternatively, when the glass body 50 is the inner glass 43 of the laminated glass 40, the shielding layer 60 can be connected to the fourth surface 432 of the inner glass 43. Under these conditions, the process for preparing the black-bordered display glass 100 can generally include forming the shielding layer 60 on the fourth surface 432 of the inner glass 43, and then laminating the inner glass 43 with the shielding layer 60 with the outer glass 41 to form the laminated glass 40. In this case, the shielding layer 60 is connected to the laminated glass 40 and, together with the laminated glass 40, forms the black-bordered display glass 100. For example, the shielding layer 60 can be applied to the fourth surface 432 of the inner glass 43 by printing.

[0121] In step S200 , the step of forming the shielding layer 60 on the glass body 50 based on the driver's eye position information may include at least steps S210 , S220 , S230 and S240 , which are described in detail below.

[0122] Please refer to Figure 4 , Figure 4 This is a schematic diagram of a state in step S210 in the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0123] S210: Design a reference line 70 based on the driver's eye position information. The orthographic projection of the reference line 70 on the glass body 50 is a reference projection 80. That is, the projection of the reference line 70 on the glass body 50 along the thickness direction of the glass body 50 is the reference projection 80.

[0124] In this step, the reference line 70 can be located on the side of the glass body 50 facing the exterior of the vehicle 200. For example, when the glass body 50 is the outer glass 41, the reference line 70 can be located on the first surface 411 of the outer glass 41. That is, the reference line 70 is located on the outer surface of the black-bordered display glass 100. When the glass body 50 is the inner glass 43, the reference line 70 can be located on the first surface 411 of the outer glass 41 or the third surface 431 of the inner glass 43. Of course, in other embodiments, the reference line 70 can also be located on the side of the glass body 50 facing the interior of the vehicle 200, and this is not a strict limitation.

[0125] In addition, the reference line 70 may extend along the width direction of the black-sided display glass 100, from one end of the black-sided display glass 100 to the other end of the black-sided display glass 100. The two ends of the reference line 70 along the width direction of the black-sided display glass 100 may not extend to the two side edges of the black-sided display glass 100 in the width direction (i.e., the left edge and the right edge in the Y-axis direction). Alternatively, at least one of the two ends of the reference line 70 along the width direction of the black-sided display glass 100 may not extend to the corresponding side edge of the black-sided display glass 100 in the width direction. For example, the left end of the reference line 70 along the width direction of the black-sided display glass 100 may not extend to the left edge of the black-sided display glass 100 in the width direction, or the right end of the reference line 70 along the width direction of the black-sided display glass 100 may not extend to the right edge of the black-sided display glass 100 in the width direction. The shape of the reference line 70 may be adapted to the outline shape of the black-sided display glass 100 in the width direction. That is, if the outline of the black-bordered display glass 100 in its width direction is a curved surface, the reference line 70 will be a curve that matches the outline of the black-bordered display glass 100 in its width direction.

[0126] For example, the length of the reference line 70 along the Y-axis may be greater than or equal to 1000 mm, but not greater than the width of the vehicle 200. It should be noted that the length of the reference line 70 along the Y-axis here refers to the straight-line distance between the two end points of the reference line 70, rather than the actual length of the reference line 70.

[0127] In this step, depending on the design requirements for the position of the shielding layer 60 in the black-bordered display glass 100, the reference projection 80 can be located on the second surface 412 of the outer glass 41, so that the shielding layer 60 manufactured later can be connected to the second surface 412 of the outer glass 41. Alternatively, the reference projection 80 can be located on the third surface 431 of the inner glass 43, so that the shielding layer 60 manufactured later can be connected to the third surface 431 of the inner glass 43. Alternatively, the reference projection 80 can be located on the fourth surface 432 of the inner glass 43, so that the shielding layer 60 manufactured later can be connected to the fourth surface 432 of the inner glass 43.

[0128] Please refer to Figure 1 , step S210 may include at least steps S211, S212, S213, S214, S215, S216 and S217, which are described in detail as follows.

[0129] S211: Establish a coordinate system with the length of the vehicle 200 as the X axis, the width of the vehicle 200 as the Y axis, and the height of the vehicle 200 as the Z axis, wherein the XZ plane is a vertical plane where the center axis of the vehicle 200 is located.

[0130] It should be noted that the origin of the coordinate system can be selected according to the actual application scenario, and there is no strict restriction on this. It only needs to satisfy that the XZ plane in the coordinate system passes through the front and rear of the vehicle 200 and divides the vehicle 200 into two symmetrical parts.

[0131] S212: Determine the driver's reference eye point M in the coordinate system.

[0132] Please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of a state in step S212 of the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 6 This is another state diagram of step S212 in the design method of the black-border display glass 100 provided in an embodiment of the present application. Step S212 may include at least the following steps:

[0133] First, the driver's eye points V1 and V2 are determined.

[0134] Among them, eye point V1 and eye point V2 represent different positions of eye point V. Point V can be determined according to the requirements of the national standard (GB 11562, Driver's forward visual field requirements and measurement methods). Point V is the point that represents the position of the driver's eyes. It is related to the driver's R point (i.e., the intersection of the seat back and the human coccyx) and the designed seat back angle. This point is used to check whether the vehicle 200's visual field meets the requirements. Figure 5 As shown, eye point V1 generally represents the highest point of the driver's eyes and can be used to determine the approximate position of the driver's eyes when the seat is adjusted to the highest position. Eye point V2 generally represents the lowest point of the driver's eyes and can be used to determine the approximate position of the driver's eyes when the seat is adjusted to the lowest position.

[0135] Next, a line segment is drawn connecting the eye point V1 and the eye point V2, and the midpoint of the line segment is recorded as the reference eye point M of the driver.

[0136] It can be understood that by determining the driver's reference eye point M through the eye point V1 and the eye point V2, factors such as the driver's sitting posture in the car, the position of the eyes, and the angle of sight can be fully considered during the preparation of the black-bordered display glass 100, thereby improving the compatibility of the prepared black-bordered display glass 100 with the driver's eye position and the driver's driving comfort.

[0137] Please refer to Figure 7 , Figure 7 This is a schematic diagram of a state in step S213 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0138] S213: Draw a straight line L passing through the reference eye point M and parallel to the Y axis. The straight line L intersects the XZ plane to form an intersection point P0.

[0139] In this step, the XZ plane may be set perpendicular to the straight line L. That is, the straight line L may be a perpendicular line to the XZ plane, and the intersection point P0 is the foot of the perpendicular line L on the XZ plane.

[0140] Please refer to Figure 8 , Figure 8 This is a schematic diagram of a state in step S214 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0141] S214 : Draw a plane S0 passing through the intersection point P0 and perpendicular to the line L. The plane S0 and the cover 211 form an intersection line C0 .

[0142] In this step, the plane S0 may coincide with the XZ plane. That is, the intersection line C0 may be the intersection line between the XZ plane and the cover 211 .

[0143] Please refer to Figure 9 , Figure 9 This is a schematic diagram of a state in step S215 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0144] S215: Form N planes S1 to S2 parallel to plane S0 along any one of the positive and negative directions of the Y axis. N Wherein, N is an integer greater than or equal to 2. N planes S1 to S N Form N intersection points P1~P with the straight line L respectively N . N planes S1~S N They also form N intersection lines C1 to C2 with the cover 211. N .

[0145] It should be noted that Figure 9 The N planes S1 to S2 are formed along the negative direction of the Y axis and are parallel to the plane S0. N The illustration is based on an example of N=5, but in other embodiments, N planes S1 to S2 parallel to the plane S0 may be formed along the positive direction of the Y axis. N , N can also be other values, and there is no strict restriction on this.

[0146] In this step, N planes S1~S N The production process is roughly as follows: along any direction of the positive or negative direction of the Y axis, N planes S1 to S1 are made at a certain interval, passing through the straight line L and parallel to the plane S0. N .

[0147] Among them, in N planes S0~SN In the above example, there is no requirement for the distance between any two adjacent planes, as long as plane S0 and plane S N The distance between them is greater than or equal to 500 mm and does not exceed half of the width of the vehicle 200. N In the example, the distances between any two adjacent planes may be equal or unequal. In addition, since plane S0 coincides with the XZ plane, the plane with a larger N value is closer to both ends of the vehicle 200 in the width direction.

[0148] For example, three planes (i.e., N = 2) can be set, including plane S0, plane S1, and plane S2. The distance between plane S0 and plane S1 is 250 mm, and the distance between plane S1 and plane S2 is also 250 mm. Therefore, the distance between plane S0 and plane S2 is 500 mm. Alternatively, the distance between plane S0 and plane S1 can be 200 mm, and the distance between plane S1 and plane S2 can be 300 mm. Alternatively, the distance between plane S0 and plane S2 can be 500 mm.

[0149] It should be noted that the distance between two planes described in the embodiments of the present application refers to the shortest distance between the two planes.

[0150] It can be understood that in this step, by making N planes S0~S N Form N intersection lines C1 to C1 with the cover 211 respectively N , indicating that during the preparation process of the black-bordered display glass 100, the impact of the position of the hood 211 on the driver's line of sight during driving has been fully considered, so that when the position of the shielding layer 60 is subsequently determined, the shielding layer 60 will not block the driver's view of the hood 211, which can improve driving safety and help the driver accurately identify the position of the entire vehicle on the road, reducing driving risks.

[0151] For a possible implementation, see Figure 9 Along the negative direction of the Y-axis, planes S1, S2, S3, S4, and S5 are sequentially drawn at equal intervals, passing through line L and parallel to plane S0. Planes S1, S2, S3, S4, and S5 intersect line L at points P1, P2, P3, P4, and P5, respectively. Planes S0, S1, S2, S3, S4, and S5 also intersect cover 211 at lines C0, C1, C2, C3, C4, and C5, respectively.

[0152] For example, among plane S1, plane S2, plane S3, plane S4 and plane S5, the distance between any two adjacent planes is 100 mm. The distance between plane S0 and plane S5 is 500 mm.

[0153] Please refer to Figure 10 , Figure 10 This is a schematic diagram of a state in step S216 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0154] S216: Draw a tangent line T0 passing through the intersection point P0 and tangent to the intersection line C0, and a tangent line T0 passing through N intersection points P1 to P N And intersect with N lines C1~C N N tangent lines T1~T N The tangent line T0 and the surface of the glass body 50 facing the outside of the vehicle 200 form an intersection point P0'. N The glass body 50 forms N intersection points P1′ to P2′ with the surface thereof facing the outside of the vehicle 200. N '.

[0155] For example, when the glass body 50 is the outer glass 41, the tangent line T0 and the first surface 411 of the outer glass 41 form an intersection point P0', and the N tangent lines T1-T N N intersection points P1′ to P2′ are formed with the first surface 411 of the outer glass 41. N '.

[0156] Alternatively, when the glass body 50 is the inner glass 43, the tangent line T0 and the first surface 411 of the outer glass 41 form an intersection point P0', and the N tangent lines T1-T N N intersection points P1′ to P2′ are formed with the first surface 411 of the outer glass 41. N '.

[0157] Alternatively, when the glass body 50 is the inner glass 43, the tangent line T0 and the third surface 431 of the inner glass 43 form an intersection point P0', and the N tangent lines T1-T N N intersection points P1′ to P2′ are formed with the third surface 431 of the inner glass 43. N '.

[0158] Of course, in some other embodiments, when the glass body 50 is the inner glass 43, the tangent line T0 may also form an intersection point P0' with the fourth surface 432 of the inner glass 43, and the N tangent lines T1-T N N intersection points P1′ to P2′ are formed with the fourth surface 432 of the inner glass 43. N ', there is no strict restriction on this.

[0159] For a possible implementation, see Figure 10 In this embodiment, N=5. Specifically, a tangent line T0 is drawn through intersection P0 and tangent to intersection C0. A tangent line T1 is drawn through intersection P1 and tangent to intersection C1. A tangent line T2 is drawn through intersection P2 and tangent to intersection C2. A tangent line T3 is drawn through intersection P3 and tangent to intersection C3. A tangent line T4 is drawn through intersection P4 and tangent to intersection C4. A tangent line T5 is drawn through intersection P5 and tangent to intersection C5. Tangent lines T0, T1, T2, T3, T4, and T5 respectively form intersections P0', P1', P2', P3', P4', and P5' with the first surface 411 of the outer glass 41.

[0160] Please refer to Figure 11 , Figure 11 This is a schematic diagram of a state in step S217 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0161] S217: Connect the intersection point P0' and N intersection points P1' to P2' in sequence N ', to form a reference line 70.

[0162] It can be understood that in step S215, by setting N to an integer greater than or equal to 2, at least two planes can be constructed. These planes intersect with the hood 211 to form at least two intersection lines, so that in step 217, at least two intersection points can be formed on the surface of the glass body 50 facing the outside of the vehicle 200. These intersection points can then be connected to ultimately form the reference line 70.

[0163] Please refer to Figure 12 and Figure 13 , Figure 12 This is another state diagram of step S217 in the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 13 This is another state diagram of step S217 in the design method of the black-border display glass 100 provided in the embodiment of the present application. Figure 13 In FIG. 7 , the first sub-line 71 and the second sub-line 72 are distinguished by a dotted line.

[0164] Step S217 may include at least the following steps:

[0165] Step 1: If Figure 12 As shown, the intersection point P0' and N intersection points P1' to P N ', to form a first sub-line 71. The first sub-line 71 is located on one side of the plane S0. That is, the first sub-line 71 is located on one side of the XZ plane.

[0166] In this step, the length of the first sub-line 71 along the Y axis is equal to the length of the plane S0 and the plane S N Exemplarily, the length of the first sub-line 71 along the Y axis may be greater than or equal to 500 mm.

[0167] Step 2: If Figure 13 As shown, a second sub-line 72 that is mirror-symmetrical to the first sub-line 71 is formed on the other side of the plane S0 (i.e., a second sub-line 72 that is mirror-symmetrical to the first sub-line 71 is formed on the other side of the XZ plane) so that the second sub-line 72 is connected to the first sub-line 71 to form a reference line 70.

[0168] In this step, the length of the second sub-line 72 along the Y axis is equal to the length of the first sub-line 71 along the Y axis. For example, the length of the second sub-line 72 along the Y axis can be greater than or equal to 500 mm. Therefore, the length of the reference line 70 along the Y axis is greater than or equal to 1000 mm. That is, the length of the reference line 70 along the Y axis can be adjusted by adjusting the plane S0 and the plane S N For example, the length of the first sub-line 71 along the Y axis and the length of the second sub-line 72 along the Y axis are both 500 mm. The length of the reference line 70 along the Y axis is 1000 mm.

[0169] The above describes the design steps of the reference line 70 in step S210. The following will describe the detailed steps S220, S230 and S240 of forming the shielding layer 60 on the glass body 50 based on the orthographic projection of the reference line 70 on the glass body 50 (i.e., the reference projection 80).

[0170] Please refer to Figure 14a 、 Figure 14b and Figure 14c , Figure 14a This is a schematic diagram of a state in step S220 of the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 14b This is another state diagram of step S220 in the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 14c This is another state diagram in step S220 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0171] S220: Based on the reference projection 80, a reference edge 90 is formed on the glass body 50. The reference edge 90 may coincide with the reference projection 80 (e.g., Figure 14a Alternatively, the distance between the reference edge 90 and the bottom edge of the glass body 50 is different from the distance between the reference projection 80 and the bottom edge of the glass body 50. That is, the reference edge 90 can be offset from the reference projection 80 (as shown). Figure 14b and Figure 14cAs shown in FIG. 1 , it is understood that the bottom edge of the glass body 50 is the bottommost side of the glass body 50 in the Z-axis direction.

[0172] In this step, the reference projection 80 and the reference edge 90 are located on the same surface. Specifically, the reference projection 80 and the reference edge 90 may both be located on the second surface 412 of the outer glass 41. Alternatively, the reference projection 80 and the reference edge 90 may both be located on the third surface 431 of the inner glass 43. Alternatively, the reference projection 80 and the reference edge 90 may both be located on the fourth surface 432 of the inner glass 43.

[0173] The distance between the reference edge 90 and the bottom edge of the glass body 50 is a first distance d1. The distance between the reference projection 80 and the bottom edge of the glass body 50 is a second distance d2. The difference between the first distance d1 and the second distance d2 is within a range of 0 mm to 20 mm (including the endpoints 0 mm and 20 mm). That is, the distance between the reference edge 90 and the reference projection 80 is within a range of 0 mm to 20 mm (including the endpoints 0 mm and 20 mm). That is, the reference edge 90 can be set within a range of 20 mm around the reference projection 80. It is understood that the difference between the first distance d1 and the second distance d2 can be equal to the absolute value of (d1-d2).

[0174] For a possible implementation, see Figure 14a , the first distance d1 is equal to the second distance d2. The difference between the first distance d1 and the second distance d2 is equal to 0, that is, the reference edge 90 coincides with the reference projection 80.

[0175] For another possible implementation, see Figure 14b The first distance d1 is smaller than the second distance d2. The difference between the first distance d1 and the second distance d2 can be 0.1 mm, 0.5 mm, 1 mm, 3 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, 16 mm, 17 mm, 18 mm, 20 mm, etc. That is, the reference edge 90 is disposed between the reference projection 80 and the bottom edge of the glass body 50.

[0176] In another possible implementation, please refer to Figure 14c The first distance d1 is greater than the second distance d2, and the difference between the first distance d1 and the second distance d2 can be 0.1 mm, 0.5 mm, 1 mm, 3 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, 16 mm, 17 mm, 18 mm, 20 mm, etc. That is, the reference projection 80 is located between the reference edge 90 and the bottom edge of the glass body 50.

[0177] Please refer to Figure 15a 、 Figure 15b and Figure 15c , Figure 15a This is a schematic diagram of a state in step S230 of the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 15b This is another state diagram of step S230 in the design method of the black-border display glass 100 provided in an embodiment of the present application. Figure 15c This is another state diagram in step S230 of the design method of the black-border display glass 100 provided in an embodiment of the present application.

[0178] S230: forming a sub-shielding layer 61 between the reference edge 90 and the bottom edge of the glass body 50.

[0179] The sub-shielding layer 61 is located within the bottom shielding region 21 of the black-bordered display glass 100 and extends along the width of the black-bordered display glass 100. The width of the black-bordered display glass 100 is parallel to the Y-axis. The sub-shielding layer 61 may include a bottom edge 611 and a top edge 612. The bottom edge 611 is the bottommost edge of the sub-shielding layer 61 in the Z-axis direction, and the top edge 612 is the topmost edge of the sub-shielding layer 61 in the Z-axis direction. The reference edge 90 forms the top edge 612.

[0180] It is understood that the position of the top edge 612 of the sub-shielding layer 61 can be determined based on the position of the reference edge 90, thereby determining the distance between the top edge 612 of the sub-shielding layer 61 and the bottom edge of the glass body 50, thereby facilitating the formation of the sub-shielding layer 61. For example, the sub-shielding layer 61 can be formed by printing black ceramic ink on the glass body 50.

[0181] For a possible implementation, see Figure 15a , the first distance d1 is equal to the second distance d2. That is, the top edge 612 of the sub-shielding layer 61 coincides with the reference projection 80. The top edge 612 is now the optimal upper boundary of the bottom shielding area 21.

[0182] For another possible implementation, see Figure 15b The first distance d1 is smaller than the second distance d2 . That is, the top edge 612 of the sub-shielding layer 61 is disposed between the reference projection 80 and the bottom edge of the glass body 50 .

[0183] In another possible implementation, please refer to Figure 15c The first distance d1 is greater than the second distance d2 . That is, the reference projection 80 is located between the top edge 612 of the sub-shielding layer 61 and the bottom edge of the glass body 50 .

[0184] The following describes the possible locations of the sub-shielding layer 61 through three specific application scenarios.

[0185] In one possible application scenario, the sub-shielding layer 61 is formed on the second surface 412 of the outer glass 41. The top edge 612 of the sub-shielding layer 61 can be arranged to coincide with the reference projection 80. Alternatively, the top edge 612 of the sub-shielding layer 61 can be arranged to be offset from the reference projection 80. For example, the sub-shielding layer 61 can be formed on the second surface 412 of the outer glass 41 by printing black ceramic between the reference edge 90 and the bottom edge of the glass body 50.

[0186] In another possible application scenario, the sub-shielding layer 61 is formed on the third surface 431 of the inner glass 43. The top edge 612 of the sub-shielding layer 61 can be arranged to coincide with the reference projection 80. Alternatively, the top edge 612 of the sub-shielding layer 61 can be arranged to be offset from the reference projection 80. For example, the sub-shielding layer 61 can be formed on the third surface 431 of the inner glass 43 by printing black ceramic between the reference edge 90 and the bottom edge of the glass body 50.

[0187] In another possible application scenario, the sub-shielding layer 61 is formed on the fourth surface 432 of the inner glass 43. The top edge 612 of the sub-shielding layer 61 can be arranged to coincide with the reference projection 80. Alternatively, the top edge 612 of the sub-shielding layer 61 can be arranged to be offset from the reference projection 80. For example, the sub-shielding layer 61 can be formed on the fourth surface 432 of the inner glass 43 by printing black ceramic between the reference edge 90 and the bottom edge of the glass body 50.

[0188] Please refer to Figure 2 S240: forming a shielding layer 60 on the glass body 50. The shielding layer 60 is disposed around the circumference of the glass body 50. The shielding layer 60 may include a sub-shielding layer 61.

[0189] In this step, the shielding layer 60 is an annular layer structure disposed around the glass body 50. Within the shielding layer 60, the shielding layers 60 in other locations, except for the sub-shielding layer 61, can be freely determined based on the vehicle 200 design and regulations. They only need to be able to connect with the sub-shielding layer 61 to form an annular shielding layer. This is not a limitation in the present embodiment.

[0190] In summary, the embodiments of the present application provide a quantitative design method for preparing black-bordered display glass 100 by combining the driver's eye position, the geometry of the hood 211, and the optical path of a panoramic head-up display (PHUD). Specifically, through geometric modeling, a tangent line between the driver's eye point and the front-most upper edge of the hood 211 is established. The intersection of several sets of tangent lines with the black-bordered display glass 100 is connected to form a curve, thereby finding the theoretical top edge 612 of the sub-shielding layer 61 of the shielding layer 60 (i.e., the upper boundary of the bottom shielding area 21). The optimal ergonomic boundary line is determined, and a certain tolerance range (0mm to 20mm) is set for appearance refinement. This achieves an optimal bottom shielding area 21 boundary design that combines the dual requirements of ergonomics and appearance.

[0191] In addition, the embodiment of the present application can maximize the area of the image display area 30 while meeting the field of view requirements by scientifically optimizing the size of the bottom shielding area 21, thereby improving the information carrying capacity of the image display area 30 and avoiding the situation where complex road conditions information is not fully displayed.

[0192] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, according to the idea of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
