Description

Technical Field

[0001] This application relates to the field of vehicle window technology, and in particular to a black-bordered display window and vehicle. Background Technology

[0002] With the evolution of the era of intelligent network connectivity, vehicles can provide various types of information to passengers, such as vehicle information, road information, and social media information. This can generally be achieved through vehicle head-up displays (HUDs), instrument panels, central control screens, passenger-side displays, and combinations thereof, to meet the needs of multi-form, near-far, and multi-level display, thereby bringing passengers a more comfortable, safe, intelligent experience and richer information.

[0003] Displays on dashboards and central control screens require drivers to look down, briefly taking their eyes off the road and creating a driving safety hazard. Traditional head-up displays (HUDs) show the image in the windshield's translucent area, with the external environment serving as the background. The brightness of the external environment and other interfering light can affect the driver's ability to see the HUD image, thus reducing driving safety and visual comfort. Summary of the Invention

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] like Figure 1 As shown, this application provides a black-rimmed display window that can be installed on a vehicle as a windshield, rear windshield, or side window. The black-rimmed display window includes a glass body 10 and a functional reflective element 20. The glass body 10 has a light-transmitting area 101 and a circumferentially arranged shielding area 102 surrounding the light-transmitting area 101. The visible light transmittance of the light-transmitting area 101 is greater than or equal to 70%, which facilitates the observation of the external environment by occupants of the vehicle. The visible light transmittance of the shielding area 102 is less than or equal to 5%, which helps to provide shielding, protection, and enhance the overall aesthetics. The functional reflective element 20 is disposed within the shielding area 102 of the glass body 10.

[0037] exist Figure 1 In the structure, the shielding area 102 includes a bottom shielding area 1021 located below the light-transmitting area 101, and the functional reflective element 20 is disposed in the bottom shielding area 1021. Optionally, the shielding area 102 also includes a left shielding area 1022 located to the left of the light-transmitting area 101, a top shielding area 1023 located above the light-transmitting area 101, and a right shielding area 1024 located to the right of the light-transmitting area 101. Preferably, the visible light transmittance of the shielding area 102 is less than or equal to 3%, more preferably less than or equal to 1%, or even equal to 0, i.e., it is opaque.

[0038] This application uses the functional reflective element 20 to reflect the projected light 301 projected by the image generation unit 30 to form an observable image, thereby partially or even completely replacing the traditional instrument panel, or even eliminating the traditional instrument panel. This allows the driver to have a better field of vision and spend more time observing the external situation, while also making it easier to obtain the necessary information for assisted driving, greatly improving driving safety. At the same time, the shading area 102 is also commonly referred to as the black border area. This application sets the functional reflective element 20 in the shading area 102, especially in the bottom shading area 1021, so that the shading area 102, especially the bottom shading area 1021, serves as the background for image display. This can better block external ambient light, avoid unnecessary interference to the line of sight, and also make the image display clearer, achieving higher contrast and color gamut.

[0039] It should be noted that when the functional reflective element 20 is in operation, it can display vehicle driving information, various patterns, or play videos, and can be used in various scenarios such as greeting guests, creating an atmosphere, watching movies, and working. Optionally, the functional reflective element 20 can be used to display driving parameters, including vehicle speed, engine speed, fuel consumption, tire pressure, warning information, mileage, etc., and can also be used to display weather temperature, entertainment information, and can be used for dynamic navigation, night vision, real-view maps, etc.

[0040] like Figure 2 As shown, in one embodiment, a black-rimmed display window is used as a windshield. The glass body 10 includes an outer glass panel 11, an adhesive layer 12, and an inner glass panel 13 stacked sequentially. The outer glass panel 11 has a first surface 111 and a second surface 112 facing away from each other. The inner glass panel 13 has a third surface 131 and a fourth surface 132 facing away from each other. The second surface 112 and the third surface 131 are opposite to each other. The adhesive layer 12 is used to bond the outer glass panel 11 and the inner glass panel 13 together to form a laminated glass structure. When the black-rimmed display window is installed on a vehicle, the outer glass panel 11 is located on the outside of the vehicle, and the first surface 111 is the exposed outer surface of the black-rimmed display window on the outside of the vehicle; the inner glass panel 13 is located on the inside of the vehicle, and the fourth surface 132 is the exposed inner surface of the black-rimmed display window on the inside of the vehicle.

[0041] The outer glass plate 11 is transparent or tinted glass with a thickness of 0.7 mm to 4 mm and a visible light transmittance greater than 70%. The inner glass plate 13 is also transparent or tinted glass with a thickness of 0.7 mm to 4 mm and a visible light transmittance greater than 70%. The total iron content (calculated as Fe2O3) of the transparent glass is less than or equal to 0.1%, even less than or equal to 0.05%, and further less than or equal to 0.01%, and the visible light transmittance of the transparent glass is 80% to 95%; the total iron content (calculated as Fe2O3) of the tinted glass is 0.1% to 0.8%, even 0.1% to 0.5%, and the visible light transmittance of the tinted glass is 75% to 90%. For example, the outer glass plate 11 can be a 2.1 mm thick transparent glass with a visible light transmittance of 89%, and the inner glass plate 13 can be a 1.6 mm thick green glass with a visible light transmittance of 83%, or a 2.1 mm thick green glass with a visible light transmittance of 80%.

[0042] The adhesive layer 12 is a transparent or colored thermoplastic polymer film, and its thickness is 0.38 mm to 2.28 mm. For example, the thickness of the adhesive layer 12 can be, but is not limited to, 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, 1.9 mm, 2.28 mm, or other values ​​between 0.38 mm and 2.28 mm. The material of the thermoplastic polymer film can be selected from at least one of polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), and ionic polymer (SGP). When the adhesive layer 12 is a transparent thermoplastic polymer, the visible light transmittance of the transparent thermoplastic polymer is greater than or equal to 80%. For example, the visible light transmittance of the adhesive layer 12 can be, but is not limited to, 80%, 85%, 90%, or 95%. When the adhesive layer 12 is a colored thermoplastic polymer film, the visible light transmittance of the colored thermoplastic polymer film is greater than 70%. For example, the visible light transmittance of the adhesive layer 12 can be, but is not limited to, 75%, 80%, 85%, or 90%. The colored thermoplastic polymer film can be a gray thermoplastic polymer film, a green thermoplastic polymer film, or a blue thermoplastic polymer film.

[0043] In some embodiments, the left-side shielding area 1022, the top shielding area 1023, and the right-side shielding area 1024 are all dark ink layers 14. Ceramic ink or ultraviolet ink is printed onto the second surface 112 using processes such as screen printing or inkjet printing, and then cured or sintered at high temperature to form the dark ink layer 14. The dark ink layer 14 is disposed around the perimeter of the second surface 112. It can be understood that the dark ink layer 14 may also be located only on the third surface 131, or only on the fourth surface 132, or simultaneously on the second surface 112 and the fourth surface 132, or simultaneously on the second surface 112 and the third surface 131, or simultaneously on the third surface 131 and the fourth surface 132, or simultaneously on the second surface 112, the third surface 131, and the fourth surface 132. To avoid mirror reflections in the left-side shielding area 1022, the top shielding area 1023, and the right-side shielding area 1024 that could interfere with the vision of occupants, the surface roughness Ra of the dark ink layer 14 is preferably greater than or equal to 1 μm, for example, 1.1 μm, 1.2 μm, 1.3 μm, 1.4 μm, 1.5 μm, 1.8 μm, 2.0 μm, 2.5 μm, 3.0 μm, 3.5 μm, or 4.0 μm. The surface roughness Ra of the dark ink layer 14 is preferably 2μm to 8μm, and even more preferably 4.5μm to 7μm, considering production cost and printing process convenience. The surface roughness Ra is also preferably 2μm to 8μm, and more preferably 4.5μm to 7μm. The surface roughness Ra value is measured using a surface roughness tester.

[0044] In this application, the area within the bottom shielding area 1021 where the functional reflective element 20 is provided is the display area, and other areas within the bottom shielding area 1021 where the functional reflective element 20 is not provided are non-display areas. The image generation unit 30 projects the projection light 301 onto the display area at an incident angle of 40° to 85°. The display area reflects the incident projection light 301 into the eyes of the occupants of the vehicle, thereby forming a display image. The display area has a first reflectivity RL1 greater than or equal to 8% for the incident projection light 301. Since the bottom shielding area 1021 serves as the display background for the display image, a clear display image can be obtained while reducing the power of the image generation unit 30 to prevent the image generation unit 30 from overheating, thereby reducing the unit size and volume of the image generation unit 30, which is beneficial for design optimization and cost reduction. Preferably, the first reflectivity RL1 is greater than or equal to 10%, and can be specifically 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, etc., more preferably greater than or equal to 15%, even more preferably greater than or equal to 20%, even greater than or equal to 25%, and even more than or equal to 30%.

[0045] In some embodiments, to reduce the interference of the mirror reflection generated by the non-display area within the bottom shielding area 1021 on the displayed image generated by the display area, the non-display area has a second reflectivity RL2 for visible light incident at an angle of incidence of 0° to 8°. Preferably, the ratio of the first reflectivity RL1 to the second reflectivity RL2 is greater than or equal to 3, i.e., RL1 / RL2 ≥ 3. Specific examples include 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20. More preferably, the ratio of the first reflectivity RL1 to the second reflectivity RL2 is greater than or equal to 5, further preferably greater than or equal to 8, even more preferably greater than or equal to 10, even greater than or equal to 15, and even more preferably greater than or equal to 20. Specifically, the second reflectivity RL2 is less than or equal to 6%, preferably less than or equal to 4%, more preferably less than or equal to 3%, even more preferably less than or equal to 2%, and even more preferably less than or equal to 1%. The first reflectivity RL1 and the second reflectivity RL2 can be measured according to the Chinese standard GB9656.

[0046] The image generation unit 30 generates projection light 301, which includes at least one of P-polarized light, circularly polarized light, and unpolarized light. Preferably, the projection light 301 contains at least 30% P-polarized light, ensuring that occupants wearing polarized sunglasses can still clearly see the displayed image. Specifically, it can contain 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or even 100% P-polarized light. The image generation unit 30 can be a projector installed inside the dashboard, with the optical path designed to display the image at a distance of 0 to 5 meters in front of the black-bordered display window. Alternatively, the image generation unit 30 can be a display screen installed on the top surface of the dashboard, with the optical path designed to display the image at a distance of 0 to 0.5 meters in front of the black-bordered display window. In this application, displaying the image at 0 meters in front of the black-bordered display window can be understood as displaying the image directly on the black-bordered display window. Specifically, the display screen can be exemplified by thin-film transistor (TFT) display screen, organic light-emitting diode (OLED) display screen, liquid crystal on silicon (LCOS) display screen, digital light processing display screen (DLP) display screen, sub-millimeter light-emitting diode (Mini LED) display screen, micro light-emitting diode (Micro LED) display screen, etc.

[0047] In some embodiments, the functional reflective element 20 can be a diffuse reflection projection layer, which has a reflectivity of at least 8% for the projection light 301 generated by the image generation unit 30. The projection light 301 forms a display image on the diffuse reflection projection layer, and the display image is directly displayed on the black-bordered display window. The diffuse reflection projection layer can achieve almost uniform reflection in all directions according to the Lambertian model, or it can preferentially have the maximum reflectivity in the direction observed by the occupants of the vehicle. Examples of the diffuse reflection projection layer include a black scattering coating, a white screen, and a transparent scattering layer element. The diffuse reflection projection layer can be disposed on the second surface 112, or between the second surface 112 and the third surface 131, or on the third surface 131, or on the fourth surface 132. Preferably, the visible light transmittance of the diffuse reflection projection layer is less than or equal to 50%, specifically 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, and 0%. More preferably, the visible light transmittance of the diffuse reflection projection layer is less than or equal to 5%, thereby allowing the diffuse reflection projection layer to serve as part of the bottom shading area 1021. Preferably, the haze of the diffuse reflection projection layer is 2% to 10%, specifically 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%.

[0048] In some embodiments, the functional reflective element 20 can be a P-polarized light reflective layer, which is used to improve the reflectivity of the display area to P-polarized light, making the reflectivity of the display area to P-polarized light greater than or equal to 8%. Examples of P-polarized light reflective layers include high-low refractive index stacks, metal stacks, and polyethylene terephthalate (PET) stacks. The visible light transmittance of the P-polarized light reflective layer is greater than or equal to 70%. The P-polarized light reflective layer can be disposed on the second surface 112, or between the second surface 112 and the third surface 131, or on the third surface 131, or on the fourth surface 132.

[0049] In some embodiments, the functional reflective element 20 can be an S-polarized light reflective layer, which is used to improve the reflectivity of the display area to S-polarized light, making the reflectivity of the display area to S-polarized light greater than or equal to 8%. Examples of S-polarized light reflective layers include high-low refractive index stacks and metal stacks. The visible light transmittance of the S-polarized light reflective layer is greater than or equal to 70%. To avoid ghosting of the displayed image, the S-polarized light reflective layer is disposed on the fourth surface 132.

[0050] In some embodiments, the functional reflective element 20 can be a mirror ink layer, which is used to increase the reflectivity of the display area to the projected light 301, making the reflectivity of the display area to the projected light 301 greater than or equal to 8%, and the visible light transmittance of the mirror ink layer less than or equal to 5%, specifically 5%, 4%, 3%, 2%, 1%, or 0%, so that the mirror ink layer can be part of the bottom shielding area 1021. The mirror ink layer can be disposed on the second surface 112, or between the second surface 112 and the third surface 131, or on the third surface 131, or on the fourth surface 132. Preferably, the surface roughness Ra of the mirror ink layer is less than or equal to 0.1 μm, more preferably less than or equal to 0.05 μm, and even more preferably less than or equal to 0.025 μm.

[0051] In some embodiments, the bottom shielding area 1021 is selected from at least one of a dark ink layer, an opaque polymer film, a dimming film, and a functional reflective element with a visible light transmittance of less than or equal to 5%. The dark ink layer can form the bottom shielding area 1021 alone, or it can be combined with the opaque polymer film, the dimming film, or the functional reflective element to form the bottom shielding area 1021; the opaque polymer film can form the bottom shielding area 1021 alone, or it can be combined with the dark ink layer, the dimming film, or the functional reflective element to form the bottom shielding area 1021; the dimming film is preferably combined with the dark ink layer or the opaque polymer film to form the bottom shielding area 1021; the functional reflective element with a visible light transmittance of less than or equal to 5% is preferably combined with the dark ink layer or the opaque polymer film to form the bottom shielding area 1021. Specifically, it can be flexibly adjusted and set according to actual needs. The bottom shielding area 1021 can be used as a display background for the displayed image, so that the displayed image is not interfered with by the brightness of the external environment, thereby improving the display effect of the functional reflective element 20.

[0052] The opaque polymer film can be a bulk-colored polymer film, such as by adding black or brown coloring components during the manufacturing process; it can also be a polymer film with surface-printed inks or pigments, such as printing black ink or brown pigments onto the surface of the polymer film; or it can be a dyed or colored polymer film, such as coloring the polymer film with black or brown dyes. 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, specifically 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 small impact on the overall thickness of the laminated glass structure. More preferably, it is less than or equal to 0.1 mm, and even more preferably, it is less than or equal to 0.05 mm.

[0053] The dimming film can be a polymer-dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), or 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%. Furthermore, the maximum visible light transmittance of the dimming film can be set as needed, for example, 10%, 20%, 30%, 50%, 70%, or 80%. Specifically, 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 of various scenarios. For example, when black border display is required, the dimming film is in an opaque state (visible light transmittance less than or equal to 5%, or even 0%), improving the contrast between the displayed image and the background. When no display is needed, the dimming film is in a transparent state (visible light transmittance greater than or equal to 70%), achieving greater transparency of the glass body 10.

[0054] Among them, the functional reflective element with a visible light transmittance of less than or equal to 5% can not only realize image display, but also serve as part of the bottom shading area 1021, which is more conducive to the combined design of the bottom shading area 1021 and the functional reflective element.

[0055] exist Figure 2 In this design, the bottom shielding area 1021 is a dark ink layer 14 disposed on the second surface 112, and the functional reflective element 20 is disposed on the third surface 131. The projection of the dark ink layer 14 onto the third surface 131 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background, which can better block ambient light, avoid unnecessary interference to the view, and make the image display clearer, achieving higher contrast and color gamut.

[0056] like Figure 3 As shown, the bottom shielding area 1021 is a dark ink layer 14 disposed on the third surface 131, and the functional reflective element 20 is disposed on the fourth surface 132. The projection of the dark ink layer 14 on the fourth surface 132 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background of the image, which can better block ambient light, avoid unnecessary interference to the view, and make the image display clearer, achieving higher contrast and color gamut.

[0057] like Figure 4As shown, the bottom shielding area 1021 is a dark ink layer 14 disposed on the fourth surface 132. The functional reflective element 20 is disposed on the dark ink layer 14, and the dark ink layer 14 completely covers the projection of the functional reflective element 20 on the fourth surface 132. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background of the image, which can better block ambient light, avoid unnecessary interference to the view, and make the image display clearer, achieving higher contrast and color gamut.

[0058] like Figure 5 As shown, the bottom shielding area 1021 is a combination of a dark ink layer 14 and a functional reflective element 20 with a visible light transmittance of less than or equal to 5%. The dark ink layer 14 is disposed on the second surface 112, and the functional reflective element 20 with a visible light transmittance of less than or equal to 5% is disposed on the third surface 131. The dark ink layer 14 has a hollow area 141, and the dark ink layer 14 partially overlaps with the functional reflective element 20. The area of ​​the functional reflective element 20 is larger than the area of ​​the hollow area 141. The functional reflective element 20 can both display images and serve as part of the background for the displayed image. The dark ink layer 14 serves as another part of the background for the displayed image, which is more conducive to the combined design of the bottom shielding area 1021 and the functional reflective element. Furthermore, it reduces the use of the dark ink layer 14 in the bottom shielding area 1021, further reducing the difficulty of the printing process and improving the bending and forming quality of the outer glass plate 11.

[0059] like Figure 6 As shown, the bottom shielding area 1021 is a combination of a dark ink layer 14 and a functional reflective element 20 with a visible light transmittance of less than or equal to 5%. The dark ink layer 14 and the functional reflective element 20 are simultaneously disposed on the second surface 112. The dark ink layer 14 has a hollowed-out area 141, within which the functional reflective element 20 is located. The functional reflective element 20 can both display images and serve as a background for the displayed images. The dark ink layer 14, acting as a shield around the functional reflective element 20, is more conducive to the combined design of the bottom shielding area 1021 and the functional reflective element. Furthermore, it reduces the use of the dark ink layer 14 in the bottom shielding area 1021, further reducing the difficulty of the printing process and improving the bending and forming quality of the outer glass plate 11. It is understood that the dark ink layer 14 and the functional reflective element 20 are also simultaneously disposed on the third surface 131 or on the fourth surface 132.

[0060] like Figure 7As shown, the bottom shielding area 1021 is a combination of a dark ink layer 14 and an opaque polymer film 15. The dark ink layer 14 is disposed on the second surface 112, and the opaque polymer film 15 is disposed in the adhesive layer 12. The functional reflective element 20 is disposed on the third surface 131. The dark ink layer 14 has a hollow area 141, and the opaque polymer film 15 partially overlaps with the functional reflective element 20. The area of ​​the opaque polymer film 15 is larger than the area of ​​the hollow area 141. The projection of the combination of the dark ink layer 14 and the opaque polymer film 15 on the third surface 131 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 and the opaque polymer film or the dimming film 15 together serve as the display background for the image, which can better block ambient light, avoid unnecessary interference to the view, and make the image display clearer, achieving higher contrast and color gamut. Furthermore, the use of the dark ink layer 14 in the bottom shaded area 1021 is reduced, further reducing the difficulty of the printing process and improving the bending quality of the outer glass plate 11. Preferably, the area of ​​the opaque polymer film 15 is larger than the area of ​​the dark ink layer 14 in the bottom shaded area 1021.

[0061] like Figure 8 As shown, the bottom shielding area 1021 is a combination of a dark ink layer 14 and a dimming film 16. The dark ink layer 14 is disposed on the second surface 112, and the dimming film 16 and the functional reflective element 20 are disposed in the adhesive layer 12. The functional reflective element 20 is located between the dimming film 16 and the third surface 131, and at least a portion of the dark ink layer 14 overlaps with the dimming film 16. The projection of the combination of the dark ink layer 14 and the dimming film 16 on the third surface 131 completely covers the projection of the functional reflective element 20 on the third surface 131. When the functional reflective element 20 displays an image, the visible light transmittance of the dimming film 16 is less than or equal to 5%, or even 0%. The dark ink layer 14 and the dimming film 16 together serve as the display background for the image, which can better block ambient light and avoid unnecessary interference with the view. It can also make the image display clearer and achieve higher contrast and color gamut. When the functional reflective element 20 does not display an image, the visible light transmittance of the dimming film 16 is greater than 5%, preferably greater than or equal to 10%, more preferably greater than or equal to 20%, further preferably greater than or equal to 50%, or even greater than or equal to 70%, thereby achieving greater transparency of the glass body 10 and providing a wider field of vision for the occupants. Furthermore, it reduces the use of the dark ink layer 14 in the bottom shielding area 1021, further reducing the difficulty of the printing process and improving the bending and forming quality of the outer glass panel 11. Preferably, the area of ​​the dimming film 16 is larger than the area of ​​the dark ink layer 14 in the bottom shielding area 1021.

[0062] This application also provides a vehicle, which includes an image generation unit 30 and a black-bordered display window of any of the above embodiments. The image generation unit 30 projects a projection light 301 at an incident angle of 40° to 85° onto a display area in a bottom shielding area 1021. The display area reflects the incident projection light 301 into the eyes of the occupants of the vehicle to form a display image.

[0063] When the black-bordered display window is installed on a vehicle, it is preferably used as the vehicle's windshield. However, it is not limited to this; the black-bordered display window can also be used as the rear windshield or side window, thus providing more display application scenarios for the vehicle.

[0064] The vehicles mentioned in this application may include, but are not limited to, passenger cars, multi-purpose vehicles (MPVs), sport / suburban utility vehicles (SUVs), off-road vehicles (ORVs), pickup trucks, vans, buses, and trucks.
