Description

[0002] Traditional car dashboards and central control screens are mainly used to display real-time vehicle information, such as speed, fuel level, map navigation, etc. During daily driving, drivers need to constantly lower or tilt their heads to look at the instrument information and central control information, and their eyes will briefly leave the road, which brings driving safety hazards.

DETAILED DESCRIPTION

[0046] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0047] See Figures 1 to 4The vehicle window glass provided in one embodiment of the present application includes a laminated glass 100, a shielding structure 200, a transition layer 300, and a reflector 400. The laminated glass 100 includes a first glass plate 110, an adhesive layer 120, and a second glass plate 130 that are stacked. The laminated glass 100 has a light-transmitting area 610 and a shielding area 620. The shielding structure 200, the transition layer 300, and the reflector 400 are arranged in the shielding area 620. The shielding area 620 is arranged circumferentially around the light-transmitting area 610. The visible light transmittance of the light-transmitting area 610 is greater than or equal to 70%, so that people in the vehicle can observe the environment outside the vehicle through the light-transmitting area 610. The visible light transmittance of the shielding area 620 is less than or equal to 3%, so that it can play a role in shielding, protection, and improving the overall aesthetics.

[0048] exist Figure 1 , the shielding area 620 includes a bottom shielding area 6201 located below the light-transmitting area 610, and the reflector 400 is disposed in the bottom shielding area 6201. Optionally, the shielding area 620 also includes a left shielding area 6202 located to the left of the light-transmitting area 101, a top shielding area 6203 located above the light-transmitting area 101, and a right shielding area 6204 located to the right of the light-transmitting area 101. Preferably, the visible light transmittance of the shielding area 620 is less than or equal to 2%, more preferably less than or equal to 1%, further less than or equal to 0.5%, or even almost equal to 0, i.e., completely opaque.

[0049] Specifically, the first glass plate 110 serves as the outer glass plate of the vehicle window glass. The first glass plate 110 has a first surface 111 in contact with the outside environment and a second surface 112 facing away from the outside environment. The second glass plate 130 serves as the inner glass plate of the vehicle window glass. The second glass plate 130 has a third surface 131 facing away from the inside environment of the vehicle and a fourth surface 132 facing away from the inside environment of the vehicle. The adhesive layer 120 connects the second surface 112 and the third surface 131.

[0050] The first glass plate 110 is transparent glass or tinted glass, has a thickness of 0.7 mm to 4 mm, and has a visible light transmittance greater than or equal to 80%. The second glass plate 130 is transparent glass or tinted glass, has a thickness of 0.7 mm to 4 mm, and has a visible light transmittance greater than or equal to 80%. 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%, 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%, preferably 0.1% to 0.5%, and the visible light transmittance of the tinted glass is 80% to 90%. For example, the first glass plate 110 can be a transparent glass with a thickness of 2.1 mm and a visible light transmittance of 89%, and the second glass plate 130 can be a green glass with a thickness of 1.6 mm and a visible light transmittance of 83%, or a green glass with a thickness of 2.1 mm and a visible light transmittance of 80%.

[0051] Wherein, the adhesive layer 120 is a transparent thermoplastic polymer film or a colored thermoplastic polymer film, and the thickness of the adhesive layer 120 is 0.38mm to 2.28mm. For example, the thickness of the adhesive layer 120 can be, but is not limited to, 0.38mm, 0.76mm, 1.14mm, 1.52mm, 1.9mm, 2.28mm, or other values ​​between 0.38mm and 2.28mm. 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 ionomer (SGP). When the adhesive layer 120 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 120 can be, but is not limited to, 80%, 85%, 90%, 95%, etc. When the adhesive layer 120 is a colored thermoplastic polymer film, the visible light transmittance of the colored thermoplastic polymer film is greater than or equal to 80%. For example, the visible light transmittance of the adhesive layer 120 may be, but is not limited to, 80%, 85%, or 90%. The colored thermoplastic polymer film may be a gray thermoplastic polymer film, a green thermoplastic polymer film, or a blue thermoplastic polymer film.

[0052] The shielding structure 200 includes a first shielding layer 210 and a second shielding layer 220 disposed in the shielding area 620. The first shielding layer 210 is disposed on the side of the reflector 400 that is closest to the first glass plate 110, i.e., the first shielding layer 210 is located between the first glass plate 110 and the reflector 400. The second shielding layer 220 is disposed on the other side of the reflector 400 that is away from the first glass plate 110. The first shielding layer 210 and the second shielding layer 220 at least partially overlap along the thickness direction of the laminated glass. In other embodiments, the first shielding layer 210 and the second shielding layer 220 completely overlap along the thickness direction (first direction) of the laminated glass.

[0053] The material of the first shielding layer 210 is selected from at least one of dark ink, an opaque polymer film, and a dimming film. The material of the second shielding layer 220 is selected from at least one of dark ink, an opaque polymer film, and a dimming film. The material of the first shielding layer 210 can be the same as or different from the material of the second shielding layer 220. The dark ink can be a ceramic ink or a UV ink. The ceramic ink or UV ink is printed on the second surface 112, the third surface 131, and / or the fourth surface 132 using a process such as screen printing or inkjet printing. After curing or high-temperature sintering, the first shielding layer 210 or the second shielding layer 220 is formed. The thickness of the first shielding layer 210 formed of dark ink is 5 to 40 microns, and the thickness of the second shielding layer 220 formed of dark ink is 5 to 40 microns. The opaque polymer film can be a body-colored polymer film, for example, by adding a black or brown coloring component during the manufacturing process; a surface-printed polymer film with ink or pigment, for example, by printing black ink or brown pigment on the surface of the polymer film; or a dyed or colored polymer film, for example, by coloring the polymer film with a black or brown dye. The polymer film can be made of polyvinyl butyral (PVB), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. The dimming film can be a polymer dispersed liquid crystal film (PDLC), suspended particle film (SPD), electrochromic film (EC), dye liquid crystal film (LC), etc. The minimum visible light transmittance of the dimming film is less than or equal to 3%, 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%. For example, the visible light transmittance of the dimming film can be adjusted between 0% and 20%, between 0.5% and 50%, and 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 3%, or even 0%), improving 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%), achieving transparency in a larger area of ​​the window glass.

[0054] The reflective member 400 is located between the first shielding layer 210 and the second shielding layer 220. The second shielding layer 220 has a through hole 221 arranged along the thickness direction (first direction) of the laminated glass. The projection of the through hole 221 on the reflective member 400 coincides with the outline of the reflective member 400 or is located within the outline of the reflective member 400.

[0055] The reflective element 400 is selected from at least one of a diffuse reflection projection layer, a P-polarized light reflection layer, an S-polarized light reflection layer, and a mirror ink layer. The reflective element 400 can be disposed on the second surface 112, between the second surface 112 and the third surface 131, on the third surface 131, or on the fourth surface 132. The diffuse reflection projection layer has a reflectivity of at least 8% for projection light, and the projection light forms a display image on the diffuse reflection projection layer, which is then directly displayed on the black-bordered display window. Examples of the diffuse reflection projection layer include a black scattering coating, a white curtain, a transparent scattering layer, and the like. The visible light transmittance of the diffuse reflection projection layer is less than or equal to 50%, and specific examples include 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%, allowing it to serve as part of the bottom shielding area 6201. The P-polarized light reflective layer is used to increase the reflectivity of the functional display area 621 for P-polarized light, so that the reflectivity of the functional display area 621 for P-polarized light is greater than or equal to 8%. The P-polarized light reflective layer can be, for example, a high-low refractive index laminate, a metal laminate, or a polyethylene terephthalate (PET) laminate. The visible light transmittance of the P-polarized light reflective layer is greater than or equal to 70%. The S-polarized light reflective layer is used to increase the reflectivity of the functional display area 621 for S-polarized light, so that the reflectivity of the functional display area 621 for S-polarized light is greater than or equal to 8%. The S-polarized light reflective layer can be, for example, a high-low refractive index laminate, a metal laminate, or the like. 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. The mirror ink layer is used to increase the reflectivity of the functional display area 621 to the projection light, ensuring that the reflectivity of the functional display area 621 to the projection light is greater than or equal to 8%. The visible light transmittance of the mirror ink layer is less than or equal to 5%, with specific examples being 5%, 4%, 3%, 2%, 1%, and 0%. This allows the mirror ink layer to serve as part of the bottom shielding area 6201. 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.

[0056] The transition layer 300 is disposed on the other side of the reflector 400 away from the first glass plate 110. The projection of the transition layer 300 on the second shielding layer 220 is at least partially located within the through-hole 221. The transition layer 300 can be located on the same surface as the second shielding layer 220, or on different surfaces. When the transition layer 300 and the second shielding layer 220 are located on the same surface, the transition layer 300 is completely located within the through-hole 221, and the outer contour of the transition layer 300 coincides with the contour of the through-hole 221. The visible light transmittance of the transition layer 300 is less than that of the second glass plate 130 and greater than that of the second shielding layer 220. In some embodiments, the thickness of the transition layer 300 is less than or equal to the thickness of the second shielding layer 220.

[0057] The material of the transition layer 300 is selected from at least one of dark ink, an opaque polymer film, and a dimming film. The material of the transition layer 300 can be the same as or different from that of the second shielding layer 220. The dark ink can be ceramic ink or UV ink. The ceramic ink or UV ink is printed on the second surface 112, the third surface 131, and / or the fourth surface 132 using a process such as screen printing or inkjet printing. The transition layer 300 is formed after curing or high-temperature sintering. The thickness of the transition layer 300 formed from the dark ink is 5 to 40 microns. The opaque polymer film can be a body-colored polymer film, for example, by adding a black or brown coloring component during the manufacturing process; a surface-printed polymer film with ink or pigment, for example, by printing black ink or brown pigment on the surface of the polymer film; or a dyed or colored polymer film, for example, by coloring the polymer film with a black or brown dye. The polymer film can be made of polyvinyl butyral (PVB), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. The dimming film can be a polymer dispersed liquid crystal film (PDLC), suspended particle film (SPD), electrochromic film (EC), dye liquid crystal film (LC), etc. The minimum visible light transmittance of the dimming film is less than or equal to 3%, 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%. For example, the visible light transmittance of the dimming film can be adjusted between 0% and 20%, 0.5% and 50%, or 0% and 70%. The dimming film can meet the brightness transition requirements in multiple scenarios. For example, when black border display is required, the visible light transmittance of the dimming film is less than that of the second glass plate 130 and greater than that of the second shielding layer 220, creating a visually comfortable brightness transition zone. When black border display is not required, the visible light transmittance of the dimming film is equal to that of the second shielding layer 220, achieving overall appearance consistency.

[0058] In the present application, the second shielding layer 220 is provided with a through hole 221 extending along the first direction, which allows the projection light of the image generating element 500 to enter and then be incident on the reflective element 400. The reflective element 400 reflects part of the incident projection light to form an image that can be observed by the driver. At this time, the driver does not need to lower his head to observe the image, allowing the driver to have a better field of vision and a longer time to observe the external situation. At the same time, it is easier to obtain the necessary information for assisted driving, greatly improving driving safety, thereby being able to partially replace or even completely replace the traditional instrument panel, or even eliminate the traditional instrument panel. At the same time, the shielding area 620 is also commonly referred to as the black edge area. In the present application, the reflective element 400 is set in the bottom shielding area 6201, so that the bottom shielding area 6201 serves as the background for image display, which can better block the external ambient light, avoid unnecessary interference with the line of sight, and make the image display clearer, achieving higher contrast and color gamut.

[0059] Furthermore, the transition layer 300 provided herein blocks the edge regions of the reflector 400 in the thickness direction (first direction) of the laminated glass, while the central region of the reflector 400 is not blocked by the transition layer 300. The central region of the reflector 400 not blocked by the transition layer 300 serves as the display portion 410 of the reflector 400. Projection light entering through the through-hole 221 is incident on the display portion 410, which reflects the projection light to form an image. Because the image brightness in the region where the display portion 410 is located is higher, while the brightness of the second shielding layer 220 is lower, there is a significant brightness contrast between the two. By providing this portion of the transition layer 300 between the display portion 410 and the second shielding layer 220, a brightness transition is achieved between the darker second shielding layer 220 and the brighter display portion 410. This reduces glare to the driver due to the significant brightness contrast, improves visual comfort, and reduces visual fatigue during extended driving, resulting in enhanced driving safety.

[0060] See Figure 1 、 Figure 2 、 Figure 12 and Figure 13Specifically, the central area of ​​the reflector 400 that is not blocked by the transition layer 300 is defined as the display portion 410. The display portion 410 is used to reflect the projection light entering through the through hole 221. The projection of the display portion 410 within the through hole 221 is the functional display area 621. The functional display area 621 is located within the shielding area 620. When no image is displayed, the shielding area 620 can effectively shield the functional display area 621, thereby improving the aesthetics. The portion of the transition layer 300 located between the display portion 410 and the second shielding layer 220 surrounds the outside of the functional display area 621 to form a visual transition area 622. The functional display area 621 is used to effectively display images, and the visual transition area 622 is used to transition the brightness between the functional display area 621 and the shielding area 620.

[0061] Functional display area 621 can display vehicle driving information, various graphics, or play videos, and can be used in various scenarios such as welcoming guests, creating an atmosphere, watching movies, and working. Optionally, it can be used to display driving parameters, including vehicle speed, engine speed, fuel consumption, tire pressure, warning messages, mileage, etc. It can also be used to display weather temperature, entertainment information, dynamic navigation, night vision, real-time map, etc.

[0062] In some embodiments, the visible light transmittance of the second glass plate 130 is greater than or equal to 80%, the visible light transmittance of the second shielding layer 220 is less than or equal to 3%, and the visible light transmittance of the transition layer 300 is greater than 3% and less than 80%, to achieve a better brightness transition. Preferably, the visible light transmittance of the transition layer 300 is between 5% and 70%. More preferably, the visible light transmittance of the transition layer 300 is between 10% and 60%. Even more preferably, the visible light transmittance of the transition layer 300 is between 20% and 50%.

[0063] See Figure 1 and Figure 2 The shielding area 620 is arranged around the outside of the light-transmitting area 610, and the function display area 621 is located in the bottom shielding area 6201. The number of the function display area 621 can be as follows: Figure 1 The one shown can also be Figure 2 Four are shown, and other quantities such as two, three or even more can also be designed according to actual products.

[0064] In some embodiments, the ratio of the total area of ​​the functional display area 621 to the area of ​​the bottom shielding area 6201 is a, 10% ≤ a ≤ 90%. It is understood that if a is less than 10%, the display effect of the functional display area 621 is not obvious, which is not conducive to more clear image display. If a is greater than 90%, the manufacturing process of the second shielding layer 220 is increased and the overall aesthetics of the vehicle window glass are not good. When the above range is met, both of the above aspects can be well balanced.

[0065] Preferably, a≤80%. At the same time, preferably, a≥30%, more preferably, a≥40%, more preferably, a≥50%.

[0066] See Figures 3 to 5 In some embodiments, the first shielding layer 210 is disposed on the second surface 112, and the second shielding layer 220 and the transition layer 300 are both disposed on the fourth surface 132. The transition layer 300 is located within the through hole 221, and the outer contour of the transition layer 300 coincides with the contour of the through hole 221. The width of the transition layer 300 extends from the contour of the through hole 221 toward the center of the through hole 221.

[0067] Specifically, the cross-sectional shape of the through hole 221 may be circular, elliptical, triangular, square, polygonal or irregular, and the transition layer 300 may match the shape thereof.

[0068] In some embodiments, the distance between the outer and inner contours of the transition layer 300 is no less than 0.5 mm, meaning the width of the transition layer 300 is no less than 0.5 mm. This allows for a more pronounced brightness transition, further improving visual comfort and reducing manufacturing complexity. Preferably, the width of the transition layer 300 is no less than 3 mm and no more than 30 mm. More preferably, the width of the transition layer 300 is no less than 5 mm and no more than 20 mm.

[0069] See Figure 11 In other embodiments, the transition layer 300 is located between the reflector 400 and the second shielding layer 220. Specifically, the transition layer 300 is located on the fourth surface 132, and the second shielding layer 220 is located on the surface of the transition layer 300 facing away from the fourth surface 132. A portion of the projection of the transition layer 300 on the second shielding layer 220 overlaps with the second shielding layer 220, while another portion is located within the through-hole 221. It is understood that the transition layer 300 can also be located on the third surface 131, and the second shielding layer 220 on the fourth surface.

[0070] See Figures 3 to 5 In some embodiments, the projection of the through hole 221 on the reflector 400 coincides with or is located within the outline of the reflector 400. Preferably, the projection of the through hole 221 on the reflector 400 is located within the outline of the reflector 400, and the distance between the outline of the projection of the through hole 221 on the reflector 400 and the outline of the reflector 400 is no less than 2 mm, so that the second shielding layer 220 can effectively shield the reflector 400, so that the reflector 400 is not exposed when the driver looks out from inside the vehicle. More preferably, the distance between the outline of the projection of the through hole 221 on the reflector 400 and the outline of the reflector 400 is no less than 5 mm, or even no less than 10 mm.

[0071] In some embodiments, the projections of the first shielding layer located in the bottom shielding area 6201 and the second shielding layer 220 located in the bottom shielding area 6201 along the thickness direction (first direction) of the laminated glass overlap with each other. When looking from outside the vehicle to inside the vehicle, the first shielding layer 210 can block the second shielding layer 220 so that it will not be exposed, which is more aesthetically pleasing.

[0072] In other embodiments, the height of the first shielding layer located in the bottom shielding area 6201 along the height direction of the laminated glass is greater than the height of the second shielding layer 220 located in the bottom shielding area 6201 along the height direction of the laminated glass. When viewed from outside the vehicle looking into the interior, the first shielding layer 210 can shield the second shielding layer 220 from being exposed, thereby enhancing the aesthetics. Specifically, the height difference between the first shielding layer 210 and the second shielding layer 220 is greater than 0 and no greater than 30 mm; alternatively, the height difference between the first shielding layer 210 and the second shielding layer 220 is greater than 1 and no greater than 25 mm; alternatively, the height difference between the first shielding layer 210 and the second shielding layer 220 is greater than 5 and no greater than 15 mm.

[0073] exist Figure 3 and Figure 4 In the embodiment, the first shielding layer 210 is located on the second surface 112 , the second shielding layer 220 is located on the fourth surface 132 , the transition layer 300 is located on the fourth surface 132 , and the reflector 400 is located on the third surface 131 .

[0074] exist Figure 6 In the embodiment, the first shielding layer 210 is located on the second surface 112 , the second shielding layer 220 is located on the third surface 131 , the transition layer 300 is located on the third surface 131 , and the reflector 400 is located on the surface of the first shielding layer 210 facing away from the first glass plate 110 .

[0075] exist Figure 7 In the embodiment, the first shielding layer 210 is located on the second surface 112, the second shielding layer 220 is located on the third surface 131, the transition layer 300 is located on the third surface 131, and the reflective element 400 is located in the adhesive layer 120. In this case, the adhesive layer 120 can be two thermoplastic polymer films, and the reflective element 400 is sandwiched between the two thermoplastic polymer films.

[0076] exist Figure 8 In the embodiment, the first shielding layer 210 is located on the second surface 112, the second shielding layer 220 is located in the adhesive layer 120, the transition layer 300 is located in the adhesive layer 120, and the reflector 400 is located on the surface of the first shielding layer 210 facing away from the first glass plate 110. In this case, the adhesive layer 120 can be two thermoplastic polymer films, and the second shielding layer 220 and the transition layer 300 are both sandwiched between the two thermoplastic polymer films.

[0077] exist Figure 9In the embodiment, the first shielding layer 210 is located on the second surface 112 , the reflector 400 is located on the fourth surface 132 , the second shielding layer 220 is located on the surface of the reflector 400 facing away from the first glass plate 110 , and the transition layer 300 is located on the surface of the reflector 400 facing away from the first glass plate 110 .

[0078] exist Figure 10 In the laminated glass, the first shielding layer 210 includes a first shielding portion 211 located on the second surface 112 and a second shielding portion 212 located in the adhesive layer 120. The first shielding portion 211 and the second shielding portion 212 at least partially overlap along the thickness direction (first direction) of the laminated glass. The second shielding layer 220 is located on the fourth surface 132, the transition layer 300 is located on the fourth surface 132, and the reflector 400 is located on the third surface 131. The first shielding portion 211 can be formed by printing dark ink on the second surface 112, and the second shielding portion 212 can be formed using an opaque polymer film or a dimming film.

[0079] exist Figure 11 In the embodiment, the first shielding layer 210 is located on the second surface 112 , the reflector 400 is located on the third surface 131 , the transition layer 300 is located on the fourth surface 132 , and the second shielding layer 220 is located on the surface of the transition layer 300 facing away from the second glass plate 130 .

[0080] See Figures 12 to 14 In some embodiments, the visible light transmittance of the transition layer 300 gradually increases along the contour of the through-hole 221 toward its center, for example, from slightly less than the visible light transmittance of the second shielding layer 220 to slightly less than the visible light transmittance of the second glass plate 130. This allows the visual transition zone 622 to gradually darken from the inside to the outside, resulting in a more uniform, less abrupt brightness change and a more natural transition effect. Preferably, the visible light transmittance of the transition layer 300 increases along the contour of the through-hole 221 toward its center from 4% to 79%, or from 5% to 75%, or from 10% to 70%, or from 15% to 65%, or from 20% to 60%.

[0081] See Figure 12 In some embodiments, the transition layer 300 includes a plurality of solid shielding patterns 310 spaced apart from each other. The material of the solid shielding patterns 310 is at least one selected from dark ink, opaque polymer film, and dimming film. The area between two adjacent solid shielding patterns 310 is not provided with any of the dark ink, opaque polymer film, and dimming film. That is, the area between two adjacent solid shielding patterns 310 is the second glass plate 130. As the total area of ​​the plurality of solid shielding patterns 310 gradually decreases along the contour of the through hole 221 toward its center, the less shielding there is, the higher the visible light transmittance. Specifically, the shape of the solid shielding pattern 310 is not limited and can be set to Figure 12The circular shape shown may also be an ellipse, polygon, or irregular shape. In this embodiment, the visible light transmittance of the transition layer 300 = (visible light transmittance of the solid shielding patterns 310 * the total area of ​​the solid shielding patterns 310 + the visible light transmittance of the area between the solid shielding patterns 310 * the total area of ​​the area between the solid shielding patterns 310) / the total area of ​​the transition layer 300.

[0082] Furthermore, multiple rows of solid shielding patterns 310 are arranged along the outline of the through hole 221 toward its center. The solid shielding patterns 310 in each row have the same area. As the outline of the through hole 221 moves toward its center, the area of ​​each row of solid shielding patterns 310 gradually decreases, and the number of solid shielding patterns 310 in each row gradually increases, achieving a more natural brightness transition.

[0083] See Figure 13 In some embodiments, the transition layer 300 includes a plurality of hollow light-transmitting patterns 320 spaced apart from each other. The area between two adjacent hollow light-transmitting patterns 320 is provided with at least one of dark ink, an opaque polymer film, and a dimming film. No dark ink, opaque polymer film, or dimming film is provided within the hollow light-transmitting pattern 320, i.e., the hollow light-transmitting pattern 320 represents the second glass plate 130. As the total area of ​​the plurality of hollow light-transmitting patterns 320 decreases along the contour of the through hole 221 toward its center, the less obstruction there is, and the higher the visible light transmittance. Specifically, the shape of the hollow light-transmitting pattern 320 is not limited and can be set to Figure 12 The circular shape shown may also be an ellipse, a polygon, or an irregular shape. In this embodiment, the visible light transmittance of the transition layer 300 = (visible light transmittance of the hollow light-transmitting patterns 320 * the total area of ​​the hollow light-transmitting patterns 320 + the visible light transmittance of the area between the hollow light-transmitting patterns 320 * the total area of ​​the area between the hollow light-transmitting patterns 320) / the total area of ​​the transition layer 300.

[0084] Furthermore, multiple rows of hollow light-transmitting patterns 320 are arranged along the outline of the through hole 221 toward its center. The hollow light-transmitting patterns 320 in each row have the same area. As the area of ​​each row of hollow light-transmitting patterns 320 increases along the outline of the through hole 221 toward its center, the number of solid shielding patterns 310 in each row gradually decreases, achieving a more natural brightness transition.

[0085] See Figure 14 In some embodiments, the transition layer 300 includes a first transition portion 330 and a second transition portion 340 connected to each other, and the second transition portion 340 is arranged around the outside of the first transition portion 330. The first transition portion 330 includes a plurality of solid shielding patterns 310 spaced apart from each other. Figure 12The second transition portion 340 includes a plurality of hollow light-transmitting patterns 320 spaced apart from each other. The arrangement of the second transition portion 340 is similar to that of the embodiment shown in FIG. Figure 13 By combining the two methods, the change in the visible light transmittance of the transition layer 300 as a whole can meet the needs of more complex scenarios.

[0086] An embodiment of the present application provides a vehicle, which includes the window glass of any of the above embodiments, and further includes an image generating member 500, which is used to project the projection light through the through hole 221 to the reflective member 400, and the reflective member 400 is used to reflect the projection light to form a display image. Figure 3 As shown, the image generating element 500 projects the projection light through the through hole 221 onto the fourth surface 132. Part of the projection light is refracted into the second glass plate 130 to form a first refracted light. After the first refracted light reaches the reflective element 400, part of the first refracted light is reflected by the reflective element 400 to form a second reflected light. Part of the second reflected light is refracted on the fourth surface 132 and emitted into the vehicle through the through hole 221, thereby forming a display image observed by the driver. To simplify the diagram, Figure 3 The specific optical path of the projection light within the second glass plate 130 is not specifically shown. When the reflector 400 is located on the fourth surface 132, the projection light is directly projected onto the reflector 400 through the through hole 221, and part of the projection light is reflected by the reflector 400 to directly form a display image observed by the driver.

The display portion 410 is configured to reflect the projection light to form a display image. The image generating element 500 is configured to generate projection light, which includes at least one of P-polarized light, circularly polarized light, and unpolarized light. Preferably, the projection light comprises at least 30% P-polarized light, so that the driver can still clearly see the displayed image even when wearing polarized sunglasses. Specifically, for example, the projection light may comprise 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or even 100% P-polarized light.

[0088] In some embodiments, the image generating unit 500 can be a projector, which is installed inside the instrument panel. Alternatively, the image generating unit 500 can be a display screen, which can be installed on the top surface of the instrument panel. Examples of such displays include thin-film transistor (TFT) displays, organic light-emitting diode (OLED) displays, liquid crystal on silicon (LCOS) displays, digital light processing (DLP) displays, sub-millimeter light-emitting diode (Mini LED) displays, and micro-light-emitting diode (Micro LED) displays.
