Abstract
Description
vehicle
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 8, 2023, with application number 202311154319.5 and application name “Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of vehicle display screens, and in particular to vehicles. Background Art
[0003] Vehicles are an essential means of transportation for humans. With the advancement of intelligent automotive connectivity, cars can now provide drivers and passengers with a wide range of information, including vehicle information, road information, ADAS, and social media feeds. This information is typically provided through head-up displays (HUDs and ARHUDs), instrument clusters, central control screens, passenger-side displays, and combinations thereof, providing multi-format, near- and far-field, multi-level displays. This delivers a more comfortable, safe, and intelligent experience, along with richer information presentation.
[0004] However, the instrument panel / center console / passenger display is typically located on the dashboard, closer to the front passenger. This proximity and spatial arrangement result in poor viewing angles for the screens. For example, this requires lowering or tilting the head to view displayed information, temporarily removing the view from the road, which can pose additional safety risks. Certain screens are susceptible to strong reflective glare in certain situations, resulting in unclear display. Head-up displays (HUDs) primarily project images through reflection off the windshield, often at long distances. This creates a degree of distortion in the virtual image, which can easily overlap and confuse objects in the forward field of view. Contrast is also insufficient, making some displayed information difficult to discern, particularly in rainy conditions or during traffic congestion.

[0055] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0056] The present application provides a vehicle 1. Referring to Figures 1 to 3, the vehicle 1 includes a vehicle body 10, an instrument panel 12, a front windshield 20, and a panoramic display screen 30. The vehicle body 10 includes a vehicle body main body 11 and a vehicle body front opening 13. The vehicle body front opening 13 is provided in the vehicle body main body 11. The instrument panel 12 is provided in the interior space of the vehicle body 11. The front windshield 20 is installed in the vehicle body front opening 13, and the front windshield 20 and the instrument panel 12 are arranged at an angle, and the angle is substantially equal to the loading angle of the front windshield 20. The loading angle of the front windshield 20 is the angle between the front windshield 20 and the horizontal plane when the front windshield 20 is in the loaded state, indicating the degree of inclination of the front windshield 20. The loading angle is generally 18° to 45°, for example, 25°, 30°, 35°, 40°, etc.
[0057] The front windshield 20 includes a light-shielding layer 21 and a transparent area 22. The light-shielding layer 21 surrounds the perimeter of the front windshield 20. The area of the front windshield 20 where the light-shielding layer 21 is located has a low visible light transmittance, shielding and protecting interior components from aging and damage caused by direct sunlight, thereby increasing the service life of the components. The light-shielding layer 21 also shields the interior components, ensuring an overall aesthetic appearance when viewed from the outside. The light-shielding layer 21 can be a dark ink layer or a colored polymer film. The light-shielding layer 21 can be formed using printing ink or other methods. Alternatively, a dark resin film with low light transmittance can be used. Alternatively, a light-colored resin film with low light transmittance can be used. Examples of such resin films include body-colored PVB and PET. The transparent area 22, which is the central area of the front windshield 20 where the light-shielding layer 21 is not located, has a high visible light transmittance that meets safety standards. Preferably, the visible light transmittance of the transparent area 22 is greater than or equal to 70%.
[0058] The light-shielding layer 21 includes an upper light-shielding layer, a left light-shielding layer, a right light-shielding layer, and a lower light-shielding layer. The upper light-shielding layer is located in the top area of the front windshield 20, the left light-shielding layer is located in the left area of the front windshield 20, the right light-shielding layer is located in the right area of the front windshield 20, and the lower light-shielding layer is located in the bottom area of the front windshield 20. The upper light-shielding layer, the left light-shielding layer, and the right light-shielding layer have a visible light transmittance of less than or equal to 1%, or even substantially equal to 0, i.e., they are opaque. The lower light-shielding layer is disposed adjacent to the instrument panel 12 and has a visible light transmittance of less than or equal to 5%, preferably less than or equal to 3%, more preferably less than or equal to 1%, or even substantially equal to 0, i.e., they are opaque.
[0059] The panoramic display screen 30 has a bottom end 301 and a top end 302, which are arranged in opposite directions. The bottom end 301 is fixed to the instrument panel 12, while the top end 302 faces away from the instrument panel 12 and is closer to the front windshield 20. The distance D between the top end 302 and the front windshield 20 is ≤ 150 mm. The panoramic display screen 30 also has a front display surface 303 and a back light-shielding surface 304, which are arranged in opposite directions. The front display surface 303 faces away from the front windshield 20, while the back light-shielding surface 304 faces the front windshield 20. The front display surface 303 has an active display area 31, and this active display area 31 is located above the instrument panel 12. The present application provides a panoramic display screen 30 on the instrument panel 12 so that the display content is between the vehicle instrument panel and the transparent field of view of the front windshield 20, providing stable and clear images for the driver and passengers. Compared with the traditional instrument panel display, the driver's line of sight can be less away from the road, thereby greatly improving driving safety. In addition, the viewing distance of the display content is more friendly, further enhancing the immersive driving experience.
[0060] In some specific embodiments, the color of the light shielding layer 21 is consistent with the color of the back light shielding surface 304, for example, both are black, brown, or brown, thereby improving the overall appearance consistency of the vehicle 1. The visible light transmittance of the panoramic display screen is less than or equal to 1%, or even substantially equal to 0, i.e., completely opaque, thereby improving the display effect of the effective display area 31.
[0061] A coordinate system of vehicle 1 is defined, with the vehicle's travel direction as the X-axis, the vehicle's width as the Y-axis, and the vehicle's height as the Z-axis. The coordinate system XYZ is the coordinate system of vehicle 1. In this application, the positive direction of the X-axis is the opposite direction of the vehicle's travel direction, the positive direction of the Y-axis is the width direction from the left side to the right side of the vehicle's travel direction, and the positive direction of the Z-axis is the direction from the ground to the sky.
[0062] The panoramic display screen 30 is disposed within the interior space of the vehicle body 11, above the instrument panel 12 and adjacent to the front windshield 20. The panoramic display screen 30 includes an active display area 31, which faces the driver and passengers and provides readable display information. Furthermore, the location of the active display area 31 above the instrument panel 12 facilitates viewing and reading of information displayed on the active display area 31 without lowering the driver's head.
[0063] In the present application, the front windshield 20 is a laminated glass structure, specifically comprising an inner glass, an outer glass, and an adhesive layer, the adhesive layer being used to connect the inner and outer glass. The light-shielding layer 21 can be disposed on the inner glass, the outer glass, and / or the adhesive layer. Specifically, as shown in FIG4 , the light-shielding layer 21 is disposed on the surface of the outer glass near the adhesive layer. Alternatively, the light-shielding layer 21 can be disposed on the surface of the inner glass near the adhesive layer, or on the surface of the inner glass facing away from the adhesive layer.
[0064] In some specific embodiments, the back shading surface 304 of the panoramic display screen 30 is black, and the visible light transmittance of the panoramic display screen 30 is 0. Since the panoramic display screen 30 is arranged close to the bottom of the front windshield 20, the lower shading layer of the shading layer 21 can be adaptively reduced in height to reduce costs.
[0065] In other specific embodiments, the lower shading layer has an upper boundary 211 and a lower boundary 212 arranged in opposite directions, the lower boundary 212 is close to the instrument panel 12, and the upper boundary 211 is close to the top 302 of the panoramic display screen 30. The lower shading layer of the shading layer 21 is used to shield the panoramic display screen 30 to avoid problems such as abrupt appearance when observed from the outside of the vehicle. Preferably, the distance between the upper boundary 211 and the upper surface of the instrument panel 12 is greater than or equal to the distance between the top 302 and the upper surface of the instrument panel 12. The lower shading layer can also serve as a secondary background when observing the panoramic display screen 30 from the inside of the vehicle, so that the overall panoramic display screen 30 looks more harmonious and beautiful with surrounding components such as the instrument panel and the shading layer 21, and to a certain extent reduces the interference of stray light from the outside environment on the effective display area 31.
[0066] In this application, the panoramic display screen 30 extends along the Y-axis and is positioned above the instrument panel 12 and near the lower light-shielding layer. This allows for a larger layout space for the panoramic display screen 30. Furthermore, because the panoramic display screen 30 is positioned relatively high, there's no need to lower your head too much to view the information displayed on the panoramic display screen 30, resulting in a better viewing angle. Compared to traditional heads-up displays, the panoramic display screen 30 is unaffected by the brightness of the exterior environment, providing an independent display experience and a higher contrast between the displayed image and the background. At the same time, the panoramic display screen 30 and the front windshield 20 in the present application are set independently of each other, which can avoid having an overly tilted angle together with the front windshield 20, so that the panoramic display screen 30 can be set at a better tilt angle to obtain a larger layout space and a more comfortable viewing angle between the front windshield 20 and the instrument panel 12, thereby increasing the area of the effective display area 31, increasing the display content, and avoiding the occurrence of darkening, color cast, etc. when the driver and passengers in the vehicle 1 observe the panoramic display screen 30.
[0067] Optionally, the information input of the panoramic display screen 30 can come from internal and external systems such as the vehicle-mounted system (VOS), various sensors, various camera systems, entertainment systems, mobile phone signals, and broadcast signals.
[0068] Referring to Figure 4 , the panoramic display screen 30 and the lower light shielding layer are both located outside the visual field B deduction zone of the front windshield 20, as viewed from the human eye. This prevents the panoramic display screen 30 from obstructing the driver's field of view in front of the vehicle 1 while driving. The human eye is the driver's eye when seated in the vehicle body 11. The visual field B deduction zone of the front windshield 20 complies with the provisions of GB9656 and / or ECE R43.
[0069] Optionally, the top 302 of the panoramic display screen 30 is non-flush to increase the display range of the panoramic display screen 30 according to actual design requirements. A majority of the top 302 is shielded by the lower light-shielding layer. Preferably, at least 55% of the top 302 is shielded by the lower light-shielding layer, i.e., at least 55% of the top 302 does not extend beyond the upper boundary 211 of the lower light-shielding layer in the Z-axis direction. More preferably, at least 60% of the top 302 is shielded by the lower light-shielding layer, or at least 70% of the top 302 is shielded by the lower light-shielding layer, or at least 80% of the top 302 is shielded by the lower light-shielding layer, or at least 90% of the top 302 is shielded by the lower light-shielding layer, or 100% of the top 302 is shielded by the lower light-shielding layer.
[0070] Referring again to Figures 1, 2, and 4, the front windshield 20 is a curved structure that convexes outward along the negative X-axis to reduce the vehicle's drag coefficient, improve resistance to external impacts, and achieve overall harmony and aesthetics. In some embodiments, the panoramic display screen 30 may be a flat plate. In other embodiments, the panoramic display screen 30 may be a curved structure that convexes outward along the negative X-axis, that is, convex toward the front windshield 20. This creates a curved structure that aligns with the front windshield 20, improving the driver's viewing experience and comfort.
[0071] Furthermore, to meet the overall requirements of the smart cockpit, the panoramic display screen 30 is an elongated strip-shaped structure, meaning the ratio of its width to its height is greater than or equal to 2, with specific examples including 2, 3, 5, 8, 10, 12, 15, and 20, more preferably greater than or equal to 5, and even more preferably greater than or equal to 10. The width of the panoramic display screen 30 is the distance it extends along the Y-axis, and is preferably at least 500 mm, with specific examples including 500 mm, 600 mm, 700 mm, 800 mm, 900 mm, 1000 mm, and 1100 mm. More preferably, the width of the panoramic display screen 30 is substantially the same as the width of the front windshield 20, creating a panoramic effect that extends from A-pillar to A-pillar. The height of the panoramic display screen 30 is the distance that the panoramic display screen 30 extends in the Z-axis direction. The height of the panoramic display screen 30 is preferably 30 mm to 250 mm, and specific examples include 30 mm, 50 mm, 80 mm, 100 mm, 150 mm, 200 mm, 250 mm, etc., which is convenient for human eye observation without blocking the driver's field of vision and is also suitable for installation on the dashboard 12.
[0072] Furthermore, the distance between the top 302 and the front windshield 20 is D≤100mm, or D≤50mm, or D≤30mm, or D≤20mm, or D≤10mm, or D≤5mm, so as to increase the distance between the panoramic display screen 30 and the human eye, further facilitate observation by the human eye, and also facilitate the use of the lower shading layer 21 as a secondary background to improve the display effect.
[0073] Optionally, the spacing between the top 302 and the front windshield 20 is designed to be non-uniform, and the shape matching design is performed specifically according to the shape of the front windshield 20, the front opening 13 of the vehicle body and other structures to improve the design aesthetics of the panoramic display screen 30 and the driver's experience.
[0074] 1 , 2 , 5 and 6 , along the width direction of the vehicle body 11 (i.e., the Y-axis direction), the panoramic display screen 30 has a central area 313 and end areas 314 located at opposite ends of the central area 313 , and the curvature radius of the central area 313 is greater than the curvature radius of the end areas 314 .
[0075] In this embodiment, the radius of curvature of the central region 313 is greater than the radius of curvature of the end portions, so that the curvature of the end portions can better match the contoured surface of the front windshield 20 closer to the A-pillar. Furthermore, the larger radius of curvature of the central region 313 makes it flatter, facilitating the driver's viewing of the information displayed on the panoramic display screen 30 and reducing manufacturing complexity.
[0076] Optionally, the radius of curvature of the end region 314 is 300 mm to 1500 mm, and the radius of curvature of the central region 313 is 1500 mm to 10,000 mm. For example, the radius of curvature of the end region 314 may be, but is not limited to, 300 mm, 600 mm, 900 mm, 1200 mm, 1500 mm, or other values between 1200 mm and 1500 mm. The radius of curvature of the central region 313 may be 1500 mm, 3000 mm, 4500 mm, 6000 mm, 7500 mm, 9000 mm, 10,000 mm, or other values between 1500 mm and 10,000 mm.
[0077] Optionally, the curvature radius of each portion of the end region 314 may have different values, which may be specifically designed based on actual installation requirements. The curvature radius of each portion of the central region 313 may have different values, which may be specifically designed based on actual installation requirements.
[0078] Referring again to FIG. 2 and FIG. 4 to FIG. 6 , in this embodiment, the panoramic display screen 30 is curved along the width direction of the vehicle body 11 .
[0079] Referring again to Figures 1 and 2, in this embodiment, the vehicle body 10 further includes a first A-pillar 14 and a second A-pillar 15, which are disposed at opposite ends of the vehicle body front opening 13 along the width direction of the vehicle body 11. The panoramic display screen 30 has a first end 315 and a second end 316 that are oppositely disposed. The first end 315 is disposed adjacent to the first A-pillar 14, and the second end 316 is disposed adjacent to the second A-pillar 15. The panoramic display screen 30 is continuously arranged along the direction from the first A-pillar 14 to the second A-pillar 15, presenting a panoramic display to the driver and enhancing the driving experience.
[0080] Referring to Figures 7 and 8, a plane passing through a first eye position and parallel to the direction of travel of the vehicle 1 is located between the first end 315 and the second end 316. A plane passing through a second eye position and parallel to the direction of travel of the vehicle 1 is located between the first end 315 and the second end 316. The first eye position is the position of the passenger's eyes when the passenger is in the first driving position within the vehicle body 11, and the second eye position is the position of the passenger's eyes when the passenger is in the second driving position within the vehicle body 11. The first driving position is the primary driving position and the second driving position is the secondary driving position, or the first driving position is the secondary driving position and the second driving position is the primary driving position.
[0081] In this embodiment, the first driving position is the primary driving position and the second driving position is the co-pilot position, or the first driving position is the co-pilot position and the second driving position is the primary driving position. The first eye position is the position of the passenger's eyes when the passenger is in the first driving position within the vehicle body 11, and the second eye position is the position of the passenger's eyes when the passenger is in the second driving position within the vehicle body 11.
[0082] For illustration, assuming the first driver's seat is the primary driver's seat and the second driver's seat is the secondary driver's seat, plane A, which passes through the first eye position and is parallel to the XZ plane, is located between the first end 315 and the second end 316. In other words, the first end 315 at least extends beyond plane A. Plane B, which passes through the second eye position and is parallel to the XZ plane, is located between the first end 315 and the second end 316. In other words, the second end 316 at least extends beyond plane B. Therefore, the field of view of the occupants in the first and second driver's seats, facing the negative direction of the X-axis, falls within the display range of the panoramic display screen 30, improving the viewing experience of the occupants of the panoramic display screen 30.
[0083] Referring to Figures 1, 2, 9, and 10, the active display area 31 of the panoramic display screen 30 comprises multiple display subareas 317 arranged along the width of the vehicle body 11. Each display subarea 317 of the active display area 31 is equipped with a display unit 3171. The display units 3171 of different display subareas 317 operate independently, and can be switched on or off depending on the input image source signal using the same or different physical display units 3171. Each display subarea 317 is configured to display different information, thereby enhancing the display richness of the active display area 31 and improving the user experience.
[0084] For example, one of the display partitions 317 is displayed by a TFT-LCD display unit 3171, another display partition 317 is displayed by a MicroLED display unit 3171, another display partition 317 is displayed by a MiniLED display unit 3171, and another display partition 317 is displayed by a MicroOLED display unit 3171; or, the multiple display partitions 317 are displayed by TFT-LCD or MicroLED display units 3171 at the same time, etc.
[0085] Optionally, the size of each display partition 317 can be designed based on actual needs. For example, a display partition 317 that needs to display important information can be designed larger. For example, the effective display area 31 includes four display partitions 317. Along the positive direction of the Y axis, the length ratio of the four display partitions 317 is 1:3:2:2 or other ratios.
[0086] In other embodiments, the effective display area 31 has multiple display partitions 317 in the vertical direction of the panoramic display screen 30, that is, when viewed from the driver's perspective toward the panoramic display screen 30, it appears as multiple display partitions 317 distributed up and down, so as to improve the display richness of the panoramic display screen 30 and thus provide a user experience.
[0087] 1, 2, 11, and 12, the panoramic display screen 30 further includes a physical partition 318, which is disposed between two adjacent display sub-areas 317. The display unit 3171 is disposed away from the physical partition 318. The physical partition 318 is not provided with a display unit 3171 and cannot display anything. This separates the two adjacent display sub-areas 317, thereby preventing light interference between the two adjacent display sub-areas 317 and improving the display quality.
[0088] Referring to Figures 1, 2, and 13, the panoramic display screen 30 also has at least one transition zone 319. The transition zone 319 is located between two adjacent display sub-areas 317, and the minimum curvature radius of the panoramic display screen 30 in the transition zone 319 is less than 300 mm, or less than 200 mm, or less than 100 mm. The transition zone 319 is located between two adjacent display sub-areas 317 that have a step difference or a large change in curvature, serving as a local sharp bend to accommodate the needs of different shapes or rapid changes in spatial curves, thereby avoiding distortion of the displayed image in the transition zone 319. For example, in the end region 314 of the panoramic display screen 30 near the A-pillar, two adjacent display sub-areas 317 are on different surfaces and have a step difference, which are connected by the transition zone 319.
[0089] Referring to Figure 14 , the display partition 317 includes multiple image blocks 3172 , and different image blocks 3172 are used to display different images. In at least one display partition 317 , a single display partition 317 includes multiple image blocks 3172 , and different image blocks 3172 can display different images, further enhancing the richness of the panoramic display screen 30 . Furthermore, there is a non-displayed area between two adjacent image blocks 3172 to form a segmentation on the screen, thereby improving the distinction of the image display and further enhancing the user experience. It should be noted that Figure 14 is for illustration only and does not limit the number, shape, position, etc. of the image blocks 3172 in each display partition 317 .
[0090] Referring to Figure 15 , the panoramic display screen 30 includes at least one electronic control unit 320. Each electronic control unit 320 is electrically connected to at least one display unit 3171 and is used to control the display of the display unit 3171. Each electronic control unit 320 includes a power supply and a control unit. Each electronic control unit 320 can independently power and control the display units 3171 of a display partition 317. Alternatively, one electronic control unit 320 can power and control the display units 3171 of multiple display partitions 317. The at least one electronic control unit 320 enables each display partition 317 to operate independently. It should be noted that Figure 15 is for illustration only and does not limit the number of display units 3171 to which each electronic control unit 320 is electrically connected, nor does it limit the number of electronic control units 320.
[0091] Referring again to Figures 1, 2, 9, and 10, in this embodiment, each display partition 317 has at least one display function, and the display functions of each display partition 317 can be switched to achieve diversified display functions. Optionally, the display functions include at least one of providing an indirect field of view (e.g., the functions of the electronic rearview mirror (CMS) and transparent A-pillars), providing vehicle status information (e.g., battery level, speed, RPM, mileage, gear position, turn signals, high beam, seatbelt reminder, low fuel / battery status, steering mode, driving mode, etc.), providing a window for an in-vehicle smart assistant (e.g., a vehicle genie, avatar / cartoon), or providing social media and smart office information (e.g., displaying incoming calls, answering and rejecting them, social communication information, WeChat, text messages, emails, voice / video conferences, weather information, and broadcast information). Preferably, the functions of the electronic rearview mirror (CMS) and transparent A-pillars are preferentially located in the two display partitions 317 at the two ends of the panoramic display screen 30 on the Y-axis, enabling a better viewing angle layout and enhancing the driving experience.
[0092] In this embodiment, the content information displayed by each display partition 317 and the location of the information displayed can be customized based on actual application, user needs, etc. For example, after the vehicle 1 is powered on, one display partition 317 can be configured to provide a view within the front blind spot of the vehicle 1 and to provide a view of the rear side of the vehicle 1 during the period after the vehicle 1 is started but before it starts to travel. Furthermore, the user of the vehicle 1 can switch the order of providing the views and / or the location of the views within the multiple display partitions 317 based on their own preferences, for example, switching from one display partition 317 to another.
[0093] Please refer to Figures 1, 2, 9 and 10 again. In this embodiment, along the center of the panoramic display screen 30 pointing to the two ends of the panoramic display screen 30 in the width direction of the vehicle body 11, the curvature radius of the panoramic display screen 30 at the multiple display partitions 317 gradually becomes smaller.
[0094] In this embodiment, along the direction parallel to the Y direction and from the center of the panoramic display screen 30 towards both ends of the panoramic display screen 30, the curvature of the panoramic display screen 30 at the multiple display partitions 317 gradually decreases. That is, the radius of curvature at the display partition 317 close to the center of the panoramic display screen 30 is greater than the radius of curvature at the display partition 317 far from the center of the panoramic display screen 30. This is beneficial for providing a flatter curvature change in the area close to the center of the panoramic display screen 30 to improve the comfort of observing the panoramic display screen 30, and at both ends of the panoramic display screen 30, it can adapt to the change of the shaping surface of the A-pillar attachment to improve the appearance aesthetics. In addition, the radius of curvature at each location within each display partition 317 can also be a variable value to adapt to the specific vehicle model design. For example, taking the radius of curvature at the middle position of the display partition 317 as the radius of curvature of the display partition 317, along the Y direction, the radii of curvature of the multiple display partitions 317 are R1, R2, R3, R4, RN in sequence, and R1 < R2 < R3 and R3 > R4 > RN are satisfied.
[0095] Please refer to FIGS. 1, FIG. 2 and FIG. 16. The panoramic display screen 30 further includes a support member 32, and the support member 32 is fixedly connected to the panoramic display screen 30 and the vehicle body 10. In another embodiment, the panoramic display screen 30 further includes a support member 32, and the support member 32 is movably connected to the panoramic display screen 30 and the vehicle body 10, and the support member 32 is used to adjust the position and attitude of the panoramic display screen 30. When the support member 32 is fixedly connected to the panoramic display screen 30 and the vehicle body 10, the support member 32 can provide stable support for the panoramic display screen 30. When the support member 32 is movably connected to the panoramic display screen 30 and the vehicle body 10, the support member 32 can adjust the position and attitude of the panoramic display screen 30 (such as lifting up and down, rotating the attitude, etc.), so that the panoramic display screen 30 can provide a more flexible position and display angle to adapt to drivers with different driving habits, drivers with different heights, etc., and improve the adaptability of the panoramic display screen 30. Optionally, one end of the support member 32 is connected to the panoramic display screen 30, and the other end of the support member 32 is connected to the vehicle body main body 11 and / or the instrument panel 12.
[0096] Referring to Figures 1 and 17 , within a vertical plane (i.e., the XZ plane) passing through the driver's reference eyepoint and parallel to the vehicle's forward direction, the angle between the line connecting the midpoint of the effective display area 31 and the driver's reference eyepoint and the horizontal line is the lower viewing angle α. This lower viewing angle α is ≤ -5°, α ≤ -8°, or α ≤ -10°. The negative sign indicates downward viewing. A larger absolute value of the lower viewing angle α indicates a lower position of the displayed information within the driver's effective display area 31. For example, the lower viewing angle α can be, but is not limited to, -5°, -6°, -7°, -8°, -9°, -10°, -11°, -12°, -13°, -14°, or -15°. Preferably, the lower viewing angle is -12° ≤ α ≤ -8°. This prevents the displayed information within the effective display area 31 from being too high and interfering with driving, while ensuring that the driver can view the information without having to lower their head too much. The driver's reference eyepoint is set in accordance with standard GB 15084.
[0097] Optionally, the effective display area 31 has a top edge 311 and a bottom edge 312 that are oppositely disposed, with the bottom edge 312 being closer to the instrument panel 12 than the top edge 311. Within a plane passing through the driver's reference eyepoint and parallel to the forward direction of the vehicle 1, the angle formed by a line connecting the top edge 311 and the bottom edge 312 with the driver's reference eyepoint is a viewing angle θ, and the viewing angle θ is ≥ 0.5°, or ≥ 3°, or ≥ 5°. This allows the panoramic display screen 30 to have a larger display range, thereby improving the user experience of the panoramic display screen 30. For example, the viewing angle θ can be, but is not limited to, 0.7°, 1.0°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 5°, 6°, 7°, 8°, etc., and preferably, the viewing angle is 1.5°≤θ≤5°.
[0098] Optionally, in a vertical plane passing through the driver's reference eyepoint and parallel to the vehicle's forward direction, the angle between the active display area 31 and the horizontal plane is defined as an attitude angle β, and this attitude angle β satisfies the following: 45°≤β≤150°. This reduces the effect of strong light from outside the vehicle 1 reflecting off the panoramic display screen 30, particularly the effect of sunlight reflected at noon. This prevents excessive reflection and glare caused by the panoramic display screen 30 reflecting this light, while also preventing or minimizing damage to components within the panoramic display screen 30 from being directly exposed to strong light. For example, the attitude angle β can be limited to 45°, 65°, 85°, 105°, 115°, 125°, 135°, 145°, 150°, or other values between 45° and 150°. Preferably, 70°≤β≤125°, and more preferably, 75°≤β≤100°.
[0099] Referring to FIG. 16 again, the panoramic display screen 30 further includes a buffer portion 33 . The buffer portion 33 is disposed between the panoramic display screen 30 and the front windshield 20 , and the hardness of the buffer portion 33 is SHORE-A ≤ 90.
[0100] In this embodiment, since both the front windshield 20 and the panoramic display screen 30 are made of hard materials, the buffer portion 33 can be provided to prevent the front windshield 20 and the panoramic display screen 30 from coming into too close contact and causing cracking. The buffer portion 33 is a thermoplastic polymer with a hardness of SHORE-A ≤ 90, which can effectively cushion the panoramic display screen 30. The buffer portion 33 can be fixed to the top 302 of the panoramic display screen 30 through integral injection molding, or can be fixed to the inner surface of the front windshield 20 through adhesive bonding, or can be fixed to the back light-shielding surface 304 of the panoramic display screen 30 through adhesive bonding. For example, the material of the buffer portion 33 can be polymethyl methacrylate (PMMA), acrylonitrile butadiene styrene (ABS), polyamide (PA), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polystyrene (PS), thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), polyvinyl butyral (PVB), polyethylene terephthalate (PET), etc.
[0101] Optionally, the panoramic display screen 30 further includes a decorative portion 34, which is fixed to the top 302 of the panoramic display screen 30 and extends in a direction away from the front windshield 20. Specifically, the decorative portion 34 can extend in a direction away from the front display surface 303, or can extend onto the front display surface 303, so as to reduce the poor visual appearance of the abrupt edge, thereby reducing the poor appearance, improving the overall aesthetics of the panoramic display screen 30, and providing a more personalized appearance. The decorative portion 34 can also reduce the impact of direct external strong light on the panoramic display screen 30 and the interference of partially reflected light from the panoramic display screen 30 on the human eye. The decorative portion 34 can be integral with the buffer portion 33, or can be combined, and the decorative portion can be fixed by bonding, attaching, inlaying, injection molding, etc.
[0102] Optionally, the light emitted by the panoramic display screen 30 includes at least one of P-polarized light, circularly polarized light, and unpolarized light. The light emitted by the panoramic display screen 30 contains at least 30% P-polarized light, so that the panoramic display screen 30 is compatible with polarized sunglasses, so that the driver and passengers can still clearly see the display information displayed on the panoramic display screen 30 after wearing polarized sunglasses. For example, it can contain 30%, or 40%, or 50%, or 60%, or 70%, or 80%, or 90%, or 95%, or even 100% P-polarized light.
[0103] Referring to Figure 18, the panoramic display screen 30 further includes an optical film 35. The optical film 35 is provided on the front display surface 303 of the panoramic display screen 30. The optical film 35 includes at least one of a visible light anti-reflection film (AR film), an anti-fingerprint film (AF film), an anti-glare film (AG film), and a composite film of a stacked 1 / 4 phase retarder and a linear polarizing film. In this embodiment, the display effect and durability of the panoramic display screen 30 can be improved by providing the optical film 35. Specifically, when the optical film 35 includes a visible light anti-reflection film, the visible light anti-reflection film can reduce the reflection and scattering of external light by the panoramic display screen 30, and can improve the transmittance and color reproduction ability of the optical surface of the panoramic display screen 30, thereby improving the display effect of the panoramic display screen 30. For example, the material of the visible light anti-reflection film can be a porous silica coating, a high-low refractive index stacked coating, etc. When the optical film 35 is an AF coating, it can improve the anti-fingerprint and anti-oil capabilities of the panoramic display screen 30, effectively preventing fingerprints and oil residue, while also increasing the hardness and wear resistance of the optical surface. For example, the AF film can be a silicone coating, an acrylic coating, a polyurethane coating, a polyacrylate coating, or an organosiloxane coating. When the optical film 35 includes an AG coating, the AG coating can reduce glare and reflections caused by light reflecting off the surface of the panoramic display screen 30, thereby improving visual comfort and clarity for the driver and passengers. For example, the AG film can be diffusely reflective PET. When the optical film 35 includes a composite film of a stacked 1 / 4 phase retarder and a linear polarizing film, external stray light passes through the linear polarizing film and the 1 / 4 phase retarder, and is converted into linearly polarized light and circularly polarized light in sequence; after being reflected by the OLED metal cathode, it is converted into circularly polarized light with opposite rotation directions; and then passes through the 1 / 4 phase retarder, it is converted into linear polarized light with a vibration direction perpendicular to the polarization direction of the linear polarizing film; the linearly polarized light cannot pass through, thereby suppressing the reflection interference of external ambient light.
[0104] Referring to Figure 19, the front windshield 20 has a transparent area 22, and the transparent area 22 includes at least one head-up display area 221. The vehicle 1 also includes a head-up display system 40, and the head-up display system 40 is used to project a head-up display image to the head-up display area 221. The panoramic display screen 30 can be used in conjunction with the head-up display system 40. The head-up display image has a better field of view and a longer virtual image distance than the image displayed on the panoramic display screen 30, so that the overall immersive driving experience is better. Preferably, the head-up display system 40 is an augmented reality head-up display system (AR-HUD), so that the picture seen by the driver is combined with the actual environment. Optionally, there can be one or more head-up display areas 221. The vehicle 1 also includes a central control screen 50, which is arranged on the side of the instrument panel 12 away from the front windshield 20. The central control screen 50 is electrically connected to the panoramic display screen 30 and the head-up display system 40. The panoramic display screen 30 and the head-up display system 40 can be adjusted and controlled through the central control screen 50, thereby improving the convenience of display adjustment.
