[0029] 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.

[0030] To overcome the shortcomings of traditional instrument panel displays, center console displays, and head-up displays (HUDs), related technologies, such as displaying in the shielded area of ​​the front windshield, particularly in the bottom shielded area between the vehicle's instrument panel and the translucent area of ​​the front windshield, use the shielded area as the display background for the displayed image. Traditionally, the shielded area is printed with black opaque ceramic ink, so displaying in the shielded area is also called black-bordered display. The content displayed in the black-bordered display can include driving information such as vehicle speed, engine speed, fuel consumption, tire pressure, dynamic navigation, night vision, real-time maps, warning information, entertainment information, and input from external smart devices. Compared with traditional head-up displays (HUDs), black-bordered displays can improve the contrast between the displayed image and the display background, making the displayed content clear enough for the human eye to observe, and reducing the energy consumption of the display elements. Compared with traditional instrument panel displays and center console displays, black-bordered displays can reduce the amount of time the human eye takes its eyes off the road and turns its head, which greatly improves driving safety.

[0031] Specifically, related technologies utilize functional display modules, including but not limited to screens and illuminators, for display. These modules are bonded to the inner surface of the glass using, for example, PVB adhesive. This not only displays various media information to vehicle occupants but also serves as a decorative feature. However, this can lead to adhesive overflow and a step between the functional display module and the glass. This step is abrupt and unsightly on the inner surface of the glass, making it unsightly and prone to damage in the event of a collision.

[0032] Based on the above reasons, the present application provides a technical solution for a vehicle window and a vehicle, which can increase the display function of the product, improve the aesthetics of the product, and reduce collision damage.

[0033] See Figure 1 and Figure 2 , Figure 1 A structural diagram of a vehicle window according to an embodiment of the present application is shown. Figure 2 Shown Figure 1 The structure shown is a cross-sectional view at AA. An embodiment of the present application provides a vehicle window, which includes a glass body 10 , a functional display module 20 and a shielding member 40 .

[0034] The glass body 10 has an inner surface facing the inner environment and an outer surface facing the outer environment.

[0035] The glass body 10 can be either a single glass sheet or a laminated glass formed by combining multiple glass sheets. This embodiment specifically uses a double-layer laminated glass as an example. Optionally, the glass body 10 includes an inner glass sheet 11, an adhesive layer 12, and an outer glass sheet 13, which are sequentially laminated and connected. The inner glass sheet 11 has a first surface 111 and a second surface 112 disposed opposite each other, and the outer glass sheet 13 has a third surface 131 and a fourth surface 132 disposed opposite each other. The second surface 112 is disposed opposite the third surface 131. The first surface 111 is also the inner surface of the glass body 10, and the fourth surface 132 is also the outer surface of the glass body 10.

[0036] In addition, the functional display module 20 has a mounting surface facing the glass body 10 , which is connected to the inner surface. The area of ​​the mounting surface 22 is smaller than that of the inner surface. The functional display module 20 cooperates with the glass body 10 to form a step.

[0037] The display surface 21 refers to the side of the functional display module 20 facing the internal environment.

[0038] Optionally, the functional display module 20 is used to display driving parameters through its display surface 21, including vehicle speed, engine speed, fuel consumption, tire pressure, warning information, mileage, etc. It can also be used to display weather temperature, entertainment information, and can be used for dynamic navigation, night vision, real-life maps, and can be used for interior luminous accessories, etc.

[0039] In addition, the mounting surface 22 corresponds to the side of the function display module 20 facing away from the interior environment.

[0040] Optionally, the vehicle window further includes a first adhesive member 30 , which is connected between the mounting surface 22 and the inner surface so that the functional display module 20 is connected and fixed to the glass body 10 .

[0041] The shielding member 40 is covered on the step, and the shielding member 40 includes a first shielding portion 41 and a second shielding portion 42 connected to the first shielding portion 41. The first shielding portion 41 is arranged at the edge of the display surface 21 of the functional display module 20, and the second shielding portion 42 is arranged on the inner surface outside the functional display module 20.

[0042] It should be noted that the internal environment refers to the environment inside the vehicle; conversely, the external environment refers to the environment outside the vehicle.

[0043] In some embodiments, the material of the first adhesive 30 can be, for example, polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), ionotropic polymer film (SGP), etc., which can achieve the connection and fixation between the mounting surface 22 of the functional display module 20 and the inner surface of the glass body 10.

[0044] The above-mentioned vehicle window has a shielding member 40 covering the step. Specifically, the shielding member 40 includes a first shielding portion 41 and a second shielding portion 42. The first shielding portion 41 is provided at the edge of the display surface 21 of the functional display module 20, and the second shielding portion 42 is provided on the inner surface outside the functional display module 20. In this way, the shielding member 40 plays a shielding role, not only shielding the hard step so that the overall appearance is not abrupt and the aesthetics is enhanced, but also playing a protective role to prevent collision damage or scratches, thereby improving the feasibility of industrial products; it can also shield the overflow defects between the functional display module 20 and the glass body 10 to prevent exposure and observation by people in the car. There is no need for trimming, thereby greatly improving the product performance of the vehicle window.

[0045] In some embodiments, the covering member 40 includes, but is not limited to, a decorative strip.

[0046] To improve the shielding effect, the shielding member 40 is specifically configured as a dark color, including but not limited to various colors such as high-gloss black, high-gloss gray, high-gloss blue, high-gloss purple, black, gray, dark gray, blue, dark blue, purple, or dark purple. The color of the shielding member 40 is ≥ level 4 according to the gray card grade of the Chinese standard gray card.

[0047] Of course, as some optional solutions, the shielding member 40 can also select the required color according to actual needs, and the gray card grade of the color can be less than level 4. The specific adjustment and setting can be flexibly made according to actual needs and is not limited here.

[0048] In some embodiments, the hardness of the shielding member 40 includes, but is not limited to, SHA (SHORE A) 60°-90°, specifically, for example, 60°, 65°, 70°, 75°, 80°, 85°, or 90°, and can be flexibly adjusted and set according to actual needs. When the hardness of the shielding member 40 is less than 60°, the hardness is relatively low, the material is relatively soft, and it is prone to collapse; when the hardness of the shielding member 40 is greater than 90°, the hardness is relatively high, resulting in a risk of easy breakage when subjected to force. Furthermore, if the flatness of the inner surface or the edge of the functional display module 20 is poor, the shielding member 40 cannot be tightly fitted to the inner surface or the edge of the functional display module 20 due to its high hardness, resulting in a gap at the installation position, which is unsightly and has low installation stability.

[0049] In some embodiments, the shielding member 40 is fixed on the inner surface and / or the edge of the functional display module 20 by various means including but not limited to bonding, welding or clamping, as long as it can be firmly connected to the inner surface and / or the edge of the functional display module 20.

[0050] In this embodiment, the shielding member 40 is connected and fixed to any one of the inner surface and the edge of the functional display module 20 , and the other one is in mutual abutment or clearance fit, which can improve the assembly efficiency of the shielding member 40 to a certain extent.

[0051] Of course, optionally, the first shielding portion 41 and the second shielding portion 42 of the shielding member 40 are respectively connected and fixed to the inner surface and the edge of the functional display module 20 , which can improve the installation stability of the shielding member 40 and prevent it from getting loose.

[0052] See also Figure 1 and Figure 2In one embodiment, the vehicle window further includes a second adhesive member 50. The second shielding portion 42 is connected to the inner surface via the second adhesive member 50, and the first shielding portion 41 abuts or loosely fits against the edge of the display surface 21 in a direction perpendicular to the display surface 21. Thus, the second adhesive member 50 disposed on the inner surface and connecting the second shielding portion 42 to the inner surface can, compared to a structure in which the second adhesive member 50 is disposed on the edge of the display surface 21 and connects the first shielding portion 41 to the functional display module 20, reduce the height of the shielding member 40 on the inner surface to a certain extent, thus preventing the shielding member 40 from being too high and thus becoming unsightly. Furthermore, the area of ​​the inner surface is significantly larger than the edge area of ​​the display surface 21, allowing the second adhesive member 50 to be larger, thereby improving installation stability.

[0053] Among them, when the first shielding portion 41 abuts against the edge of the display surface 21 in a direction perpendicular to the display surface 21, compared with the clearance fit method, it is more conducive to the shielding member 40 being stably and seamlessly fixed on the glass body 10, preventing the shielding member 40 from falling off the glass body 10.

[0054] Based on the above embodiment, the second adhesive member 50 includes, but is not limited to, tape, PVB material, EVA material, TPU material, or SGP material, as long as it can achieve adhesive fixation between the second shielding portion 42 and the inner surface. In this embodiment, the second adhesive member 50 is preferably tape, specifically double-sided tape, which facilitates the installation of the shielding member 40 on the inner surface without causing adhesive overflow, and provides a high degree of flatness after installation.

[0055] In one embodiment, a first protrusion 411 is provided on the side of the first shielding portion 41 away from the second shielding portion 42, which abuts against the display surface 21. In other words, a relief recess 412 is provided on the side of the first shielding portion 41 closer to the second shielding portion 42. The relief recess 412 cooperates with the display surface 21 to form a cavity without abutting against the display surface 21. As such, only the first protrusion 411 of the first shielding portion 41 abuts against the display surface 21, resulting in a smaller contact area with the display surface 21. Force is concentrated at the point where the first protrusion 411 and the display surface 21 contact each other, thereby allowing the side of the first shielding portion 41 away from the second shielding portion 42 to cling to the edge of the display surface 21. This effectively avoids interference with the functional display module 20 and warping and wrinkling defects that would occur if the entire surface of the first shielding portion 411 were in contact with the display surface 21 in the absence of the first protrusion 411.

[0056] In some embodiments, the distance between the side of the second shielding portion 42 facing the inner surface and the inner surface is smaller than the distance between the side of the first shielding portion 41 facing the inner surface and the inner surface. Along the arrangement direction of the first shielding portion 41 and the second shielding portion 42, the second shielding portion 42 abuts against the side wall of the functional display module 20, and the abutting position is as follows: Figure 2 As shown by the arrow K in the figure, it plays a role in rapid positioning during the assembly process, is suitable for automated tooling installation, and is conducive to improving assembly efficiency.

[0057] Of course, as some optional solutions, along the arrangement direction of the first shielding portion 41 and the second shielding portion 42, the second shielding portion 42 and the side wall of the functional display module 20 do not need to abut each other, but instead provide an assembly gap, for example. The assembly gap includes, but is not limited to, 1 mm to 5 mm, specifically, 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm, etc. This makes manual assembly suitable.

[0058] In some embodiments, the first protrusion 411 abuts the display surface 21, leaving the recess 412 and the display surface 21 free to form a cavity. Along the alignment of the first and second shielding portions 41, 42, the second shielding portion 42 abuts against the sidewall of the functional display module 20. In a direction perpendicular to the inner surface, the second shielding portion 42 is secured to the inner surface via adhesive tape. This securely attaches the shielding member 40 to the inner surface while preventing it from tilting, resulting in a smoother and more aesthetically pleasing overall appearance.

[0059] In some embodiments, the side of the first shielding portion 41 and the second shielding portion 42 facing away from the inner surface may include, but is not limited to, a plane parallel to the inner surface, an inclined surface at an angle, or an irregular shape, which can be configured according to actual needs. In this embodiment, the side of the first shielding portion 41 and the second shielding portion 42 facing away from the inner surface may be, for example, a plane parallel to the inner surface, resulting in a smooth and aesthetically pleasing product appearance.

[0060] In one embodiment, the second shielding portion 42 is provided with a second protrusion 421 extending toward the inner surface on a side away from the first shielding portion 41. The second protrusion 421 is spaced apart from the inner surface. In this way, the second protrusion 421 not only provides a shielding function but also enhances the waterproof and dustproof effect. Furthermore, when the first protrusion 411 abuts the display surface 21, due to the space between the second protrusion 421 and the inner surface, the second shielding portion 42 is firmly bonded to the inner surface via the second adhesive 50, compared to a structure in which the second protrusion 421 abuts the inner surface, and is not easily loosened. This prevents over-positioning and resulting weak adhesion defects caused by the first protrusion 411 and the second protrusion 421 abutting the display surface 21 and the inner surface at the same time.

[0061] In some embodiments, the size d of the gap between the second protrusion 421 and the inner surface satisfies: 0 < d ≤ 1 mm. Specifically, for example, it can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm. Thus, when the value of d does not exceed 1 mm, the size d of the gap is small, which can play a good shielding role, has a good waterproof and dustproof effect, and can avoid the unappealing appearance when the size of the gap is too large.

[0062] Of course, as some optional solutions, d can also be any value greater than 1 mm.

[0063] In some embodiments, the distance h between the side of the first shielding portion 41 facing away from the display surface 21 and the display surface 21 includes but is not limited to being set as 1 mm ≤ h ≤ 3 mm. Specifically, for example, it can be 1 mm, 2 mm or 3 mm, etc. Thus, when the distance h is less than 1 mm, due to the small distance h, it will result in not meeting the machining accuracy requirements of the machine, making it impossible to manufacture the shielding member 40. When the distance h is too large, that is, the thickness of the first shielding portion 41 in the direction perpendicular to the display surface 21 is too large, causing material waste and increasing the cost.

[0064] In addition, along the arrangement direction of the first shielding portion 41 and the second shielding portion 42, the width W1 of the first shielding portion 41 includes but is not limited to being set as 1 mm ≤ W1 ≤ 15 mm. Specifically, for example, it can be 1 mm, 3 mm, 4 mm, 5 mm, 7 mm, 10 mm or 15 mm. Additionally, the width W2 of the second shielding portion 42 includes but is not limited to being set as 1 mm ≤ W2 ≤ 20 mm. Specifically, for example, it can be 1 mm, 3 mm, 4 mm, 5 mm, 7 mm, 10 mm, 15 mm or 20 mm. Thus, if the sizes of the width W1 and the width W2 are set too small, it will affect the shielding effect and cause the defect of being prone to looseness. If they are set too large, it will lead to material waste.

[0065] Of course, as some optional solutions, h can also be set as any value greater than 3 mm. In addition, W1 can also be set as any value greater than 15 mm, and W2 can also be set as any value greater than 20 mm. This embodiment does not limit this here.

[0066] In some embodiments, along the arrangement direction of the first shielding portion 41 and the second shielding portion 42, the width W1 of the first shielding portion 41 and the width W2 of the second shielding portion 42 satisfy the relationship: 0.2 < W1 / W2 < 1. Among them, W1 / W2 is specifically, for example, 0.3, 0.5, 0.7, 0.8 or 0.9, etc. Thus, the width W1 is small, and the area occupied by the edge of the display surface 21 is relatively small, making the display area of the display surface 21 larger. At the same time, the width W2 is large, so that the width of the second bonding member 50 can be larger, which is conducive to firmly bonding the shielding member 40 to the inner surface and not being prone to looseness.

[0067] Of course, in some optional solutions, W1 / W2 can also be any value less than or equal to 0.2 and greater than or equal to 1, and can be flexibly adjusted and set according to actual needs.

[0068] In one embodiment, the glass body 10 is provided with a light-transmitting area 101 and a shielding area 102 arranged on the periphery of the light-transmitting area 101. Specifically, the shielding area 102 is arranged circumferentially around the light-transmitting area 101. The visible light transmittance of the light-transmitting area 101 is greater than or equal to 70%, and is used for the visible area; at least one functional display module 20 is provided and arranged in the shielding area 102, and the visible light transmittance of the shielding area 102 is less than or equal to 10%, which can be used as a display background for the displayed image, so that the displayed image is not affected by the brightness of the external environment of the vehicle, thereby improving the display effect of the functional display module 20. Among them, the functional display module 20 is arranged in the shielding area 102 of the glass body 10, which means that along the direction perpendicular to the surface of the glass body 10, the projection of the functional display module 20 on the glass body 10 is all located inside the shielding area 102. In addition, the vehicle windows include, but are not limited to, the front windshield, rear windshield, side windshields, or sunroof glass. The vehicle window in this application is exemplified by the front windshield, and the shielding area 102 is the opaque area of ​​the front windshield. The functional display module 20 can be a one-piece structure, or it can be provided as a plurality, such as two, three, or any other number, and arranged separately from each other. For example, the functional display module 20 is provided as a plurality, and the plurality of functional display modules 20 can be arranged in the bottom shielding area 1021 near the instrument panel on the front windshield, or can be arranged separately in the bottom shielding area 1021 near the instrument panel, the side shielding area 1023 near the A-pillar, and the top shielding area 1022 near the interior rearview mirror.

[0069] Of course, as some optional solutions, the functional display module 20 can also be arranged in the light-transmitting area 101. Compared with being arranged in the light-transmitting area 101, arranging the functional display module 20 in the shielding area 102 can fully utilize the shielding area 102, while not blocking the line of sight due to being arranged in the light-transmitting area 101. Therefore, the structural form of being arranged in the light-transmitting area 101 is not specifically described in this embodiment.

[0070] Among them, since the glue overflow defects and the steps formed on the side of the functional display module 20 close to the light-transmitting area 101 are easily observed, in this embodiment, the shielding member 40 is at least arranged on the side of the functional display module 20 close to the light-transmitting area 101, or is only arranged on the side of the functional display module 20 close to the light-transmitting area 101, thereby achieving a better shielding effect, making the product more beautiful, and saving materials.

[0071] In another embodiment, the shielding member 40 is arranged around the circumference of the functional display module 20 .

[0072] Since the glue overflow defect and the step formed on the side of the functional display module 20 away from the light-transmitting area 101 are close to the edge and are therefore not easily observed by people inside the vehicle, optionally, the shielding member 40 is not arranged on the side of the functional display module 20 away from the light-transmitting area 101, and the shielding member 40 is arranged on the rest of the functional display module 20. In this way, a better shielding effect is achieved, making the product more beautiful, while saving materials.

[0073] In some embodiments, the outer contour of the function display module 20 includes, but is not limited to, a rectangle, a circle, an ellipse, a triangle, a pentagon, or other regular and irregular shapes. In this embodiment, a commonly used rectangle is used as an example for illustration.

[0074] When the outer periphery of the function display module 20 is set to a rectangle, in one example, Figure 1 or Figure 3 As shown, a shielding member 40 is arranged on the side of the functional display module 20 facing the light-transmitting area 101; in another example, as shown in FIG. Figure 4 As shown, the shielding member 40 is not arranged on the side of the function display module 20 away from the light-transmitting area 101 , and the shielding members 40 are arranged on the other three sides of the function display module 20 .

[0075] In one embodiment, the functional display module 20 can be a projection display component, specifically including a reflective element, which cooperates with an image light source located inside the vehicle to reflect the projection light of the image light source to form a display image to the human eye.

[0076] When there are multiple functional display modules 20, a single image light source can be used to emit multiple projection lights to different functional display modules 20; alternatively, multiple image light sources can be used, each emitting projection lights to a corresponding functional display module 20. Furthermore, the multiple displayed images can all be virtual images, all be real images, or a combination of both.

[0077] In another embodiment, the functional display module 20 may also be a self-luminous display component, specifically including an image generating element that emits light and directly transmits the displayed image to the human eye. The image generating element includes, but is not limited to, a light-emitting panel, a thin-film transistor display (TFT), an organic light-emitting diode display (OLED), a liquid crystal on silicon (LCOS), a digital light processing display (DLP), a sub-millimeter light-emitting diode display (Mini LED), a micro light-emitting diode display (Micro LED), and the like.

[0078] In another embodiment, the multiple functional display modules 20 may also include both image generating elements and reflective elements, so that they can be self-luminous displays or projected displays in conjunction with image light sources.

[0079] Optionally, the proportion of P-polarized light in the projection light emitted by the image light source is 30% to 100%, making it suitable for use with polarized sunglasses to meet the needs of more driving scenarios.

[0080] In a specific embodiment, the shielding area 102 includes a bottom shielding area 1021 located below the light-transmitting area 101, and the functional display module 20 is disposed in the bottom shielding area 1021. Optionally, the shielding area 102 also includes a top shielding area 1022 located above the light-transmitting area 101 and side shielding areas 1023 located on both sides of the light-transmitting area 101. The visible light transmittance of the bottom shielding area 1021, the top shielding area 1022, and the side shielding areas 1023 are each flexibly adjusted and set according to actual needs, for example, less than or equal to 5%, more preferably less than or equal to 3%, and even more preferably less than or equal to 1%.

[0081] In one embodiment, the glass body 10 further includes a first light-blocking layer 14 disposed in a position and shape adapted to the bottom shielding region 1021. Specifically, the first light-blocking layer 14 includes, but is not limited to, being located on the first surface 111, the second surface 112, the third surface 131, the fourth surface 132, or within the adhesive layer 12. The first light-blocking layer 14 can be flexibly adjusted and positioned based on actual needs. The first light-blocking layer 14 is made of a material with low transmittance, thereby forming the bottom shielding region 1021 in the glass body 10.

[0082] The adhesive layer 12 is sandwiched between the second surface 112 and the third surface 131, and is used to bond the outer glass panel 13 to the inner glass panel 11 to form a laminated glass structure. Materials such as polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and ionomeric polymer film (SGP) can be used. Of course, the adhesive layer 12 can also have other functions, such as providing at least one tinted area to act as a shadow band to reduce sunlight interference to the human eye, or adding infrared absorbers to provide sun protection or heat insulation. It can also include at least two layers, one of which has a higher plasticizer content to provide sound insulation, or one of which is wedge-shaped to form a head-up display (HUD) function in the light-transmitting area 101.

[0083] In one embodiment, the vehicle window further includes a second light-blocking layer 60. The second light-blocking layer 60 can be disposed on the mounting surface 22 or in an area on the inner surface corresponding to the functional display module 20. In this manner, the second light-blocking layer 60 at least partially overlaps with the first light-blocking layer 14 along the thickness direction of the glass body 10, serving as a display background for the displayed image. This protects the displayed image from interference from the brightness of the exterior environment, further enhancing the display quality of the functional display module 20.

[0084] In one embodiment, the visible light transmittance of the first light-blocking layer 14 is less than or equal to 5%, more preferably less than or equal to 3%, even more preferably less than or equal to 1%, or even less than or equal to 0.5%, or substantially 0%, i.e., it is completely opaque to visible light. The first light-blocking layer 14 is a dark-colored printed layer or a dark-colored polymer film. The material of the second light-blocking layer 60 can also be a dark-colored printed layer or a dark-colored polymer film consistent with that of the first light-blocking layer 14.

[0085] The dark printing layer may be black or brown ceramic ink or ultraviolet ink, and may be printed on the first surface 111 , the second surface 112 , the third surface 131 or the fourth surface 132 by screen printing, inkjet printing or other processes.

[0086] In addition, the dark polymer film can be a polymer film with body coloring, for example, a coloring component is added during the manufacturing process of the polymer film to obtain black or brown PVB, PET, PVC, etc.; or a polymer film with surface printing pigments, for example, black or brown pigments are printed on the surface of the polymer film, etc.

[0087] In another embodiment, the first light blocking layer 14 is a dimming film, which may be a polymer dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a liquid crystal film (LC), or the like.

[0088] In one embodiment, the minimum visible light transmittance of the dimming film is less than or equal to 5%, such as 3%, 2%, 1%, 0.5%, or 0%. In addition, the maximum visible light transmittance of the dimming film can be set as needed, such as 10%, 20%, 30%, 50%, 70%, or 80%.

[0089] For example, the visible light transmittance of the switchable film can be adjusted between 0% and 20%, between 0.5% and 50%, or between 0% and 70%.

[0090] It meets the requirements of visible light transmittance 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%), which improves the contrast between the displayed image and the displayed background. When no display is performed, the dimming film is in a transparent state (visible light transmittance is greater than or equal to 70%), which enables a larger area of ​​the glass body 1010 to be transparent.

[0091] The following specifically describes the function display module 20 including a reflective element as an example.

[0092] In one embodiment, the functional display module 20 includes a reflective element. The reflective element can be a single layer or a multi-layer structure. Taking a single-layer thin-film structure as an example, the thickness of the reflective element is generally approximately the thickness of the inner glass plate 11. The thickness of the reflective element is set to ≤ 2.5 mm, such as 2.0 mm, 1.0 mm, or 0.5 mm. The specific thickness can be flexibly adjusted and set according to actual needs.

[0093] In one embodiment, the material of the reflective element can be the same as that of the inner glass plate 11 or different from each other, and can be a single medium or a composite material.

[0094] It should be noted that the main reflective surface of the reflective element is used to reflect the projection light. The main reflective surface can be located inside the reflective element or on any surface of the reflective element, and can be specifically set according to actual conditions.

[0095] In one embodiment, the reflective element can be a single-layer structure or a multi-layer structure. Specific examples include a single piece of physically tempered glass, a single piece of chemically tempered glass, laminated glass, polycarbonate (PC), polymethyl methacrylate (PMMA), a transparent substrate or an opaque substrate deposited with a P-polarized light reflective coating, a multi-layer resin laminate, etc.

[0096] In one embodiment, the reflective element can be a polarization conversion composite layer that can realize the mutual conversion between P-polarized light and S-polarized light. Specific examples include a 1 / 2 wave plate, a stack of a 1 / 2 wave plate and a circularly polarized reflector, a 1 / 4 wave plate, and a stack of a 1 / 4 wave plate and a circularly polarized reflector.

[0097] In one embodiment, the reflective element is a composite layer with a holographic film, thereby achieving non-specular reflection and allowing for more flexible setting of the incident angle of the light source.

[0098] In one embodiment, the first light blocking layer 14 may have an electric heating element on the side close to the interior of the vehicle, and the electric heating element includes but is not limited to metal wire, copper foil, printed silver paste, transparent conductive layer, etc., which is used to realize electric heating to defrost and defog the functional display module 20.

[0099] In one embodiment, a transparent conductive layer is provided on the fourth surface 132 of the outer glass plate 13. This transparent conductive layer provides heat insulation by reflecting infrared rays and can also provide heating by applying an electric current to the transparent conductive layer. The electric heating element and the transparent conductive layer are independent components and can have different input voltages, conductive contacts, and power densities.

[0100] See also Figure 1 and Figure 2 In one embodiment, the present application also provides a vehicle, including but not limited to a car, a jeep, a bus, a truck, an airplane, a train, a taxi, a coach, etc. The vehicle includes the window of any of the above embodiments.

[0101] In the above-mentioned vehicle, since the shielding member 40 is covered on the step, specifically, the shielding member 40 includes a first shielding portion 41 and a second shielding portion 42. The first shielding portion 41 is provided at the edge of the display surface 21 of the functional display module 20, and the second shielding portion 42 is provided on the inner surface outside the functional display module 20. In this way, the shielding member 40 plays a shielding role, not only shielding the hard steps so that the overall appearance is not abrupt and the aesthetics is enhanced, but also playing a protective role to prevent collision damage or scratches, thereby improving the feasibility of industrial products; it can also shield the overflow defects between the functional display module 20 and the glass body 10 to prevent exposure and observation by people in the car, without the need for trimming, thereby greatly improving the product performance of the car window.
