The display device comprises an imaging film, a transparent screen and an image projection device. The imaging film is attached to the surface of the transparent screen. The image projection device is used for generating P light and projecting an image to the imaging film through the P light. The transparent screen is arranged at an angle with the outer surface of the center console.

Description

Technical Field

[0001] This application relates to the technical field of vehicle-mounted displays, and more particularly to a driver's cockpit and vehicle. Background Technology

[0002] The cockpits of the automotive, aerospace, and marine industries are equipped with a large number of displays, such as instrument panel screens, main unit screens, and smart displays on the center console. Currently, most of the displays used in smart cockpits are LCD (Liquid Crystal Display) screens. However, using LCD screens is not only expensive, but also lacks a sense of technology and obstructs the view of the occupants. Utility Model Content

[0003] Embodiments of this application provide a driver's cockpit and vehicle to enhance the technological feel of the driver's cockpit.

[0004] In a first aspect, embodiments of this application provide a driver's cockpit, including a center console and a display device disposed on the center console. The display device includes an imaging film, a transparent screen, and an image projection device. The imaging film is attached to the surface of the transparent screen. The image projection device generates P-light and projects a projected image onto the imaging film using the P-light. The transparent screen is set at an angle to the outer surface of the center console. The image projection device generates P-light and projects a projected image onto the imaging film using the P-light. The P-light projected by the image projection device hits the surface of the imaging film at a certain angle, thereby reproducing the object light information during the recording process of the imaging film to form an image on the imaging film. In this embodiment, the scheme of generating P-light using an image projection device and forming an image in conjunction with an imaging film effectively reduces or avoids the problem of ghosting caused by side-view lines because P-light has low reflectivity over a wide range of incident angles. Furthermore, since the image projection device eliminates S-light when generating P-light, it prevents S-light scattering at the transparent screen interface, effectively preventing the image information projected by the image projection device from being seen through the windshield from outside the passenger compartment, thus ensuring privacy and security within the passenger compartment. In addition, since the transparent screen and the imaging film attached to its surface are both transparent, it not only expands the field of vision for the occupants but also enhances the technological feel of the cockpit by projecting images onto the transparent screen and imaging film. Moreover, the scheme of forming an image using P-light and an imaging film is less expensive than the LCD screen scheme.

[0005] In addition, the imaging film in this embodiment, based on micro-nano structure to modulate light waves, is only micrometers thick and lightweight, while LCDs require a liquid crystal layer and a backlight module, and HUDs (Head-Up Displays) rely on complex projection optical paths, resulting in significantly larger size and weight. Furthermore, the imaging film in this embodiment supports multi-focal points, polarization multiplexing, and dynamic wavefront shaping, enabling simultaneous imaging, 3D display, and optical communication, while LCDs can only modulate amplitude, and HUDs have limited functionality. Additionally, the vibration-resistant and long-life characteristics of the imaging film in this embodiment make it suitable for the vibration environment of automotive applications; while LCDs may experience a decrease in response speed or backlight degradation after extreme temperatures or prolonged use.

[0006] In some embodiments, the center console includes an instrument panel located in front of the driver's seat and the front passenger seat. A transparent screen is disposed on the upper surface of the instrument panel, forming an angle with the upper surface of the instrument panel. An imaging film is attached to the surface of the transparent screen facing the inside of the passenger compartment. In this embodiment, since the instrument panel is located in front of the driver's seat and the front passenger seat, placing the transparent screen on the upper surface of the instrument panel allows both the driver's seat and the front passenger seat occupants to easily see the image projected onto the imaging film by the image projection device.

[0007] In some embodiments, the transparent screen is located between the driver's seat and the passenger seat in the width direction of the cockpit. In this embodiment, the transparent screen is positioned in the middle of the upper surface of the dashboard, and can replace the traditional central display screen on the dashboard. Because the central display screen has a small display area, it can display limited content and has a poor viewing experience. In this embodiment, since the transparent screen with the imaging film attached is positioned in the middle of the dashboard, and both the transparent screen and the imaging film attached to its surface are transparent, a larger transparent screen can be used without affecting the visibility of the occupants or the driver, thus not compromising driving safety. Furthermore, it effectively enhances the overall technological feel when displaying images.

[0008] In some embodiments, the surface of the transparent screen facing the interior of the passenger compartment is curved. The diffraction direction of the imaging film on the curved surface facing the driver's seat is towards the driver's seat, and the diffraction direction of the imaging film on the curved surface facing the passenger seat is towards the passenger seat. In this embodiment, by making the surface of the transparent screen to which the imaging film is attached curved, the transparent screen can simultaneously face the driver's seat, the passenger seat, and the rear seats. Therefore, the image information projected by the image projection device onto the imaging film on the curved surface can be clearly seen by the occupants in the driver's seat, the passenger seat, and the rear seats simultaneously, without the need for an additional rotating structure, thus reducing the cost of the display device.

[0009] In some embodiments, the surface of the transparent screen facing the inside of the passenger compartment is planar. The driver's cabin also includes a rotating structure for driving the display device to rotate, and is capable of rotating the transparent screen to face the driver's seat, front passenger seat, or rear seats. Because the surface of the transparent screen facing the inside of the passenger compartment is planar, when the imaging film is attached to the planar surface, it is easier to control the incident angle of the light projected by the P-light engine, thereby reducing light reflectivity and minimizing or avoiding the impact of ghosting on the viewing experience. Furthermore, the rotating structure allows the driver, front passenger, and even rear passengers to see the image information projected onto the imaging film by the image projection device, effectively solving the problem that a planar surface cannot provide a wide viewing angle. In addition, the rotatable display device enhances the technological feel of the passenger compartment and improves the user experience.

[0010] In some embodiments, the transparent screen includes a first plane facing the driver's seat, a second plane facing the passenger seat, and a curved surface facing the rear seats. The curved surface connects the first and second planes. An imaging film is attached to each of the first, second, and curved surfaces. The diffraction direction of the imaging film on the first plane is towards the driver's seat to ensure the driver can see the image. The diffraction direction of the imaging film on the second plane is towards the passenger seat to ensure the passenger can see the image. The diffraction direction of the imaging film on the curved surface is towards the rear seats to ensure the rear passengers can see the image. This eliminates the need for an additional rotating structure, thus reducing the cost of the display device.

[0011] In some embodiments, the image projection device is used to project at least one of the following onto the imaging film: time, map navigation, lyrics, photos, temperature, humidity, warning information, operation feedback synchronization information, call reminders, caller name / number + virtual answer / hang-up buttons, personalized quotes, AR virtual pet / assistant, 3D cartoon character interaction, or air quality index. Because the transparent screen and the imaging film attached to its surface are entirely transparent, they do not obstruct the normal vision of the driver and other passengers, allowing the transparent screen to be designed to be larger to display more information, such as multiple types of the aforementioned information simultaneously.

[0012] In some embodiments, the transparent screen is positioned directly in front of the driver's cockpit, and the image projection device is used to project instrument information onto the imaging film. In this embodiment, the scheme of projecting P-light onto the imaging film using a P-light optical engine to form image information not only reduces costs but also allows for a larger image size compared to that on the instrument panel, making it easier for the driver to view clearly. Furthermore, since the transparent screen and the imaging film attached to the transparent screen are transparent, they do not obstruct the driver's normal field of vision.

[0013] In some embodiments, the instrument information includes at least one of the following: time, map navigation, lyrics, real-time vehicle speed, warning information, blind spot monitoring information, remaining driving range, combined battery / fuel level, tire pressure monitoring, incoming call reminders, driver status monitoring, or passenger cabin interaction information. It is understood that the instrument information may also include other information, such as weather information like temperature and humidity, to facilitate driver warnings.

[0014] In some embodiments, the transparent screen is the windshield of the driver's cockpit. Because the transparent screen is the windshield of the driver's cockpit, the imaging film can be directly applied to the existing windshield of the passenger compartment, and this effect can be achieved in any area of ​​the windshield, resulting in a very high-tech look without taking up space under the steering wheel.

[0015] In some embodiments, the transparent screen extends from directly in front of the driver's seat to directly in front of the passenger seat in the width direction of the driver's cockpit. Because the transparent screen extends from directly in front of the driver's seat to directly in front of the passenger seat in the width direction of the driver's cockpit, it can provide a sufficiently large size for displaying images, enabling the display of more image information.

[0016] In some embodiments, the image projection device includes a first image projection device, a second image projection device, and a third image projection device. The first image projection device is located on the dashboard corresponding to the driver's seat, the second image projection device is located on the dashboard corresponding to the passenger seat, and the third image projection device is located on the dashboard, positioned between the first and second image projection devices in the width direction of the driver's cabin. The first image projection device projects instrument information onto the area of ​​the imaging film corresponding to the driver's seat, the second image projection device projects entertainment information onto the area of ​​the imaging film corresponding to the passenger seat, and the third image projection device projects host information onto the area of ​​the imaging film corresponding to the middle portion of the driver's and passenger seats. In this embodiment, by using the first, second, and third image projection devices to project different image information onto the diffraction light film in different areas of the transparent screen, the driver in the driver's seat can see the instrument information needed for driving, the passenger in the passenger seat can see the entertainment information, and all occupants in the passenger cabin can see the host information, thereby improving the user experience. Furthermore, in this embodiment, since the transparent screen extends from the position directly opposite the driver's seat to the position directly opposite the passenger seat in the width direction of the driver's cabin, there is no need to set up a display device to replace the traditional smart display and a display device to replace the instrument panel. This makes the passenger cabin more integrated. Moreover, since the transparent screen and the imaging film are transparent, they can effectively improve the neatness and aesthetics of the center console and enhance the overall sense of technology.

[0017] In some embodiments, the instrument information includes at least one of the following: time, map navigation, lyrics, real-time vehicle speed, warning information, blind spot monitoring information, remaining driving range, combined battery / fuel level, tire pressure monitoring, incoming call reminders, driver status monitoring, or passenger cabin interaction information;

[0018] Entertainment information includes at least one of the following: lyrics, videos, photos, synchronized operation feedback information, and passenger cabin interactive information;

[0019] The host information includes at least one of the following: time, map navigation, lyrics, video, photos, temperature, humidity, warning information, operation feedback synchronization information, call reminders, caller name / number + virtual answer / hang-up button, personalized quotes, AR virtual pet / assistant, 3D cartoon character interaction, or air quality index and passenger cabin interactive information. It is understood that instrument information can also include entertainment information and host information, and similarly, entertainment information can include instrument information and host information, and host information can also include instrument information and entertainment information.

[0020] In some embodiments, the image projection device is located on the upper surface of the dashboard, and the housing of the image projection device has a fixing part. The transparent screen is fixed to the fixing part of the housing and is set at an angle to the upper surface of the housing. In this embodiment, since the transparent screen is fixed to the housing of the image projection device, and the housing of the image projection device is fixed to the dashboard, the dashboard only needs to consider how to fix and connect it to the image projection device when designing it, and the upper surface of the dashboard can be designed to be smoother and cleaner.

[0021] In some embodiments, the center console also includes a gear shift mount integrated with the instrument panel. The gear shift mount is located between the driver's seat and the passenger seat in the width direction of the driver's cabin. A transparent screen is disposed on the upper surface of the gear shift mount, forming an angle with the upper surface of the gear shift mount. In this embodiment, by providing a transparent screen on the gear shift mount to display images on an imaging film, operability is increased while still decorating the gear shift mount. For example, users can interact with the transparent screen to perform operations such as electronic gear shifting, and the overall design is highly technological.

[0022] In some embodiments, the incident angle of the image projection device onto the imaging film is 25°-68°. When the incident angle of the image projection device onto the imaging film is within this range, the reflectivity of the P-light is low, which can effectively reduce the impact of ghosting on the passenger's viewing experience.

[0023] In some embodiments, the driver's cockpit also includes an angle adjustment structure located on the center console. This structure is connected to a transparent screen and is used to adjust the angle between the transparent screen and the outer surface of the center console. Since the angle adjustment structure can adjust the angle between the transparent screen and the outer surface of the center console—for example, adjusting the angle between the transparent screen and the upper surface of the dashboard—for instance, when the occupant reclines their seat, the structure can drive the transparent screen to tilt forward toward the inside of the passenger compartment. This ensures a better relative position between the occupant and the transparent screen, improving the viewing experience for the occupant in different postures.

[0024] In some embodiments, the image projection device includes a P-ray optical engine and a reflector. The P-ray generated by the P-ray optical engine is projected onto the reflector, which reflects the P-ray projected by the P-ray optical engine onto the imaging film. The placement of the reflector allows for more flexible positioning of the P-ray optical engine, facilitating miniaturization of the image projection device. For example, the P-ray optical engine and reflector can be housed within the casing of the image projection device, or the image projection device can be designed with a cylindrical casing, which is not only aesthetically pleasing and technologically advanced but also reduces the overall size of the image projection device.

[0025] In some embodiments, the P-ray engine and the reflector are located on opposite sides of the transparent screen along its thickness. This arrangement not only facilitates angle adjustment of the P-ray beam emitted by the P-ray engine by the reflector, but also allows for miniaturization of the image projection device. Furthermore, since the P-ray engine is located on the side of the transparent screen away from the imaging film, the heat generated by the P-ray engine can be prevented from affecting the imaging film, thus avoiding thermal deformation. It is understood that...

[0026] In some embodiments, the P-optical engine includes an image generation module (DLP) and a polarizer. This P-optical engine features high contrast, high response speed, and strong resistance to ambient light.

[0027] Alternatively, the image generation module LCOS, with its P-optical engine, can reduce optical loss and support ultra-high resolution and precise phase modulation.

[0028] Alternatively, an image generation module LCD can be used. This solution features a low-cost, mature P-optical engine and easy-to-integrate transmissive polarization modulation.

[0029] In some embodiments, the imaging film is a HOE thin film. In this embodiment, the HOE thin film is based on the principle of holographic interference, utilizing a photosensitive material to record the interference fringes of the object light and reference light, forming a microstructure to diffract and control the optical path. It achieves optical functions by changing the phase, wavelength, and propagation direction of the light wave, replacing traditional refractive / reflective elements. It is not only ultra-thin and flexible, significantly reducing the weight of the optical system, but also can integrate multiple optical functions, supporting wide-angle and large-area fabrication, and can significantly improve optical efficiency and integration.

[0052] The following section will first explain some of the terms used in the embodiments of this application.

[0053] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0054] In this specification, the terms "vertical" and "parallel" are explained.

[0055] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0056] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, allowing for situations where the parallelism is not absolute due to factors such as assembly tolerances, design tolerances, and structural flatness. These situations may lead to the sliding mating part and the first door panel not being absolutely parallel, but this application also defines such situations as parallelism.

[0057] With the rapid development of smart cockpits, numerous displays are installed in cockpits across the automotive, aerospace, and maritime sectors, including instrument clusters, main unit screens, and even decorative displays. Currently, most displays used in smart cockpits are LCD (Liquid Crystal Display) screens; however, LCD screens are not only costly but also lack a high-tech feel. Therefore, this application provides a display device that is not only low-cost and technologically advanced but also effectively improves the field of vision for occupants. The display device in this embodiment can be applied to vehicles, as well as to other modes of transportation such as airplanes, spacecraft, and ships. For ease of description, this application uses an in-vehicle display device as an example. However, it should be understood that this should not be construed as limiting the scope of this application.

[0058] Figure 1 This is a schematic diagram of the structure of a vehicle 1 provided in an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the structure of the cockpit 2 in the embodiment.

[0059] Reference Figure 1 and Figure 2 In this embodiment, vehicle 1 includes a driver's cabin 2 and wheels 3. The driver's cabin 2 includes a passenger compartment 10 and a center console 20, a display device 30, a driver's seat 41, a front passenger seat 42, and rear seats 43, all located within the passenger compartment 10. The center console 20 is located in front of the driver's seat 41 and the front passenger seat 42. That is, along the length of the driver's cabin 2, the center console 20, the driver's seat 41, the front passenger seat 42, and the rear seats 43 are arranged sequentially from front to back.

[0060] Specifically, refer to Figure 2In this embodiment, the center console 20 includes an instrument panel 21 located in front of the driver's seat 41 and the passenger seat 42, and a gear shift mounting platform 22 located between the driver's seat 41 and the passenger seat 42. The instrument panel 21 and the gear shift mounting platform 22 can be a single, integrated design or separate designs. The gear shift mounting platform 22 separates the driver's seat 41 and the passenger seat 42, effectively preventing accidental interference from the passenger in the passenger seat 42. Furthermore, the gear shift mounting platform 22 can also be used to install a gear shifter, provide cup holders, a wireless charging dock, or a storage compartment. It is understood that the display device 30 in this embodiment can be located not only on the instrument panel 21 but also on the gear shift mounting platform 22. The instrument panel 21 can not only house the display device 30 but can also be used to install a gear shifter, a storage compartment, a steering wheel, an instrument panel, or a main unit display screen. The display device 30 in this embodiment does not require a traditional LCD screen, which is more technological. The display device 30 can be used to replace one or more of the instrument panel, host display screen or central control display wizard on the traditional center console 20.

[0061] It is understandable that in some other implementations, the gear shift mounting platform 22 may be omitted, and only the instrument panel 21 may be retained.

[0062] Figure 3 for Figure 2 A schematic diagram of the structure of the intelligent cockpit after the hidden passenger compartment 10 is shown in the embodiment; Figure 4 for Figure 3 A schematic diagram illustrating the working principle of the display device 30 in this embodiment.

[0063] Reference Figure 3 and Figure 4 In this embodiment, the display device 30 includes a transparent screen 31, an imaging film 32, and an image projection device 33.

[0064] The transparent screen 31 can be made of transparent glass or transparent plastic, etc. Compared to traditional non-transparent LCD screens, the transparent screen 31 avoids obstructing the view of the occupants inside the passenger compartment 10, thus effectively increasing the occupants' effective field of vision. The transparent screen 31 is mounted on the center console 20, specifically at an angle to the outer surface of the center console 20, for example... Figure 3 As shown in the embodiment, the transparent screen 31 is disposed on the upper surface of the instrument panel 21, and is set at an angle to the upper surface of the instrument panel 21, for example, at a 90-degree angle, that is, the upper surface of the instrument panel 21 and the transparent screen 31 are perpendicular to each other, so as to facilitate viewing by the occupants in the passenger compartment 10. It is understood that in some other embodiments, the transparent screen 31 may also be disposed on the gear shift mounting platform 22.

[0065] The imaging film 32 has periodic or non-periodic microstructures (such as gratings, nanopillars, etc.) designed on its surface or inside. When light passes through the microstructure, the phase delay difference at different positions forms wavefront shaping, achieving focusing, beam splitting, or polarization control. Based on the Huygens-Fresnel principle, the light wavefront is reconstructed using the diffraction effect. When light passes through the periodic or non-periodic subwavelength structure, the phase delay difference at different positions changes the propagation path of the light. Through the synergistic effect of interference and diffraction, focusing or an image is formed at a specific position. The imaging film 32 provides precise control of the light wavefront through its structure, replacing the refractive imaging of traditional lenses, and achieving ultra-thin, lightweight, or complex light field manipulation.

[0066] The imaging film 32 can be a holographic optical element (HOE), or it can be an embossed grating, a metasurface, or a photonic sieve, etc.

[0067] A Holographic Image (HOE) may include a substrate layer and a holographic recording layer. The substrate layer is typically a transparent thin film material, such as a photopolymer film or a polyimide film. These materials possess excellent optical transparency and mechanical properties, enabling the recording of holograms. The holographic recording layer sits atop the substrate layer and can be fabricated using materials such as aromatic acrylates or pyrrolidone. The holographic recording layer records the interference fringes between the object light wave and the reference light wave using the principles of holography, forming a grating structure. This records the amplitude and phase information of the light wave, determining the diffraction characteristics of the HOE. Furthermore, the HOE may include a protective layer to protect the holographic recording layer from environmental damage. This protective layer can be a transparent organic or inorganic material, possessing properties such as scratch resistance and corrosion resistance.

[0068] Because of its high diffraction efficiency, HOE ensures that most of the incident light is effectively used for image reconstruction, producing a sufficiently bright reconstructed image even in bright light environments. Simultaneously, HOE exhibits angle selectivity and wavelength selectivity, selectively enhancing the brightness of the target image while suppressing stray light from other directions, significantly improving image contrast and sharpness. Since HOE operates based on the principle of light diffraction, unlike traditional display technologies that rely on the intensity contrast of reflected or transmitted light to display information, it can still produce a clear image in bright light environments, effectively resisting ambient light interference, even with strong ambient light.

[0069] The imaging film 32 is attached to the surface 311 of the transparent screen 31, specifically, the imaging film 32 can be attached to the surface 311 of the transparent screen 31 facing the inside of the passenger compartment 10. Since the imaging film 32 is also transparent, the display panel composed of the imaging film 32 and the transparent screen 31 is also transparent, which will not affect the view of passengers inside the passenger compartment 10. Moreover, since the image information is displayed on a transparent display panel, it appears to be highly technological.

[0070] The image projection device 33 generates P-light and projects the image onto the imaging film 32. The reproduction light (P-light) projected by the image projection device 33 hits the surface of the imaging film 32 at a certain angle, thereby reproducing the object light information recorded by the imaging film 32 to form an image on the imaging film 32. In this embodiment, in the scheme of forming an image by the P-light generated by the image projection device 33 and the imaging film 32, since the reflectivity of P-light is low in most incident angle ranges, the problem of ghosting on the side of the eyeball can be effectively reduced or avoided. Moreover, since the image projection device 33 generates P-light and eliminates S-light, the scattering of S-light at the interface of the transparent screen 31 can be avoided, thereby effectively preventing the image information projected by the image projection device 33 from being seen through the windshield 11 outside the passenger cabin 10, thus ensuring the privacy and security of the passenger cabin 10.

[0071] Furthermore, since the imaging film 32 in this embodiment is based on micro-nano structure to control light waves, its thickness is only on the micrometer scale, making it lightweight. In contrast, LCDs require a liquid crystal layer and a backlight module, while HUDs (Head-Up Displays) rely on complex projection optical paths, resulting in significantly larger size and weight. Moreover, the imaging film 32 in this embodiment supports multi-focus, polarization multiplexing, and dynamic wavefront shaping, enabling simultaneous imaging, 3D display, and optical communication, while LCDs can only modulate amplitude, and HUDs have limited functionality. Additionally, the vibration resistance and long lifespan of the imaging film 32 in this embodiment make it suitable for the vibration environment of automotive applications; whereas LCDs may experience a decrease in response speed or backlight degradation after extreme temperatures or prolonged use.

[0072] Reference Figure 3 and Figure 4 In this embodiment, the image projection device 33 includes a P-light optical engine 331 and a reflector 332. The P-light generated by the P-light optical engine 331 is projected onto the reflector 332, which reflects the P-light projected by the P-light optical engine 331 onto the imaging film 32. The placement of the reflector 332 allows for more flexible positioning of the P-light optical engine 331, facilitating miniaturization of the image projection device 33. For example, the P-light optical engine 331 and the reflector 332 can both be housed within the casing 333 of the image projection device 33. Figure 3The cylindrical housing 333 is not only aesthetically pleasing and technologically advanced, but also reduces the size of the image projection device 33. It is understood that in some other embodiments, the reflector 332 may be omitted, and light may be projected directly onto the imaging film 32 via the P-light engine 331. Furthermore, the housing 333 of the image projection device 33 can be not only cylindrical, but also angular, rhomboid, or other shapes.

[0073] In this embodiment, the P-light optical engine 331 is used to generate P-light while filtering other light rays, such as S-light. Any device capable of generating P-light falls under the category of the P-light optical engine 331 in this embodiment. For example, in some implementations, the P-light optical engine 331 includes a DLP (Digital Light Processing) and a polarizer. The DLP uses a DMD (Digital Micromirror Device) array of micromirrors to reflect unpolarized light and controls the light intensity distribution by rapidly flipping the micromirrors. When the reflected light passes through the polarizer, only the P-light (linearly polarized light parallel to the incident plane) aligned with the transmission axis of the polarizer passes through, while other polarization components are blocked. By modulating the reflection path and polarization filtering, P-polarized light is output in a directional manner to achieve the purpose of projecting P-light onto the imaging film 32. The P-light optical engine 331 in this embodiment has high contrast, high response speed, and resistance to ambient light intensity.

[0074] In other embodiments, the P-optical engine 331 can also be an image generation module LCOS (Liquid Crystal on Silicon). LCOS modulates the polarization state through a silicon-based reflective liquid crystal layer: after incident P-light (linearly polarized) penetrates the liquid crystal layer, the liquid crystal molecules are voltage-controlled to change their polarization direction; the light reflected to the silicon substrate passes through the liquid crystal layer a second time, and the polarization state is precisely modulated. Finally, a polarizer filters out specific P-light components to achieve the purpose of projecting P-light onto the imaging film 32. In this embodiment, the P-optical engine 331 can reduce light loss and support ultra-high resolution and precise phase modulation.

[0075] In other embodiments, the P-optical engine 331 can also be an image generation module LCD. The LCD is based on transmissive liquid crystal polarization control: the unpolarized light from the backlight is converted into P-light by the front polarizer, and the liquid crystal molecules change the polarization direction of the light according to the twist angle of the electrical signal; the rear polarizer (analyzer) only allows light with the same direction as the original P-light to pass through, while the other components are blocked, so as to achieve the purpose of projecting P-light onto the imaging film 32. The P-optical engine 331 in this embodiment is low in cost, technologically mature, and easy to integrate with transmissive polarization modulation.

[0076] Reference Figure 4In this embodiment, the P-light mechanism 331 and the reflector 332 are located on opposite sides of the transparent screen 31 in the thickness direction of the transparent screen 31. Specifically, the reflector 332 can be located on the side of the transparent screen 31 where the imaging film 32 is located. By positioning the P-light mechanism 331 and the reflector 332 on opposite sides of the transparent screen 31 in the thickness direction, it is not only beneficial for the reflector 332 to adjust the angle of the P-light emitted by the P-light mechanism 331, but also for the miniaturization design of the image projection device 33. Furthermore, since the P-light mechanism 331 is located on the side of the transparent screen 31 away from the side where the imaging film 32 is located, the heat generated by the P-light mechanism 331 can be avoided from affecting the imaging film 32, thus preventing thermal deformation of the imaging film 32. It is understood that in some other embodiments, the P-light mechanism 331 and the reflector 332 can be placed on the same side of the transparent screen 31 in the thickness direction. Moreover, the number of reflectors 332 is not limited; they can be placed on the same side of the transparent screen 31. Figure 4 The embodiment may have only one reflector 332, or it may have multiple reflectors 332.

[0077] Reference Figure 3 In this embodiment, the transparent screen 31 is disposed on the upper surface of the dashboard 21, and in the width direction Y of the driver's cabin 2, the transparent screen 31 is located between the driver's seat 41 and the passenger seat 42. In this embodiment, the transparent screen 31 is disposed in the middle of the upper surface of the dashboard 21, and can be used to replace the traditional sprite display in the middle of the dashboard 21. Since the sprite display has a small display area, it can display less content and has a poor viewing experience. In this embodiment, since the transparent screen 31 with the imaging film 32 attached is disposed in the middle of the dashboard 21, a larger transparent screen 31 can be disposed without affecting the field of vision of the occupants in the passenger compartment 10, nor the driver's field of vision, and therefore does not affect the driver's driving safety. Moreover, since the transparent screen 31 with the imaging film 32 attached is transparent, it can improve the overall technological feel when displaying images.

[0078] Specifically, Figure 3 The image projection device 33 in this embodiment is used to project one or more of the following onto the imaging film 32: time, map navigation, lyrics, images, photos, temperature, humidity, warning information, operation feedback synchronization information, call reminders, caller name / number + answer / hang up virtual buttons, personalized quotes, AR virtual pets / assistants, 3D cartoon character interaction, or air quality index.

[0079] Reference Figure 3In this embodiment, the image projection device 33 is mounted on the upper surface of the dashboard 21. The housing 333 of the image projection device 33 has a fixing part 3331. The transparent screen 31 is fixed to the fixing part 3331 of the housing 333, and is set at an angle to the upper surface of the housing 333. Since the transparent screen 31 is fixed to the housing 333 of the image projection device 33, and the housing 333 of the image projection device 33 is fixed to the dashboard 21, the dashboard 21 only needs to be designed to be fixedly connected to the image projection device 33, allowing for a smoother and cleaner upper surface design.

[0080] like Figure 3 As shown, the fixing part 3331 on the housing 333 of the image projection device 33 is a fixing groove, and the transparent screen 31 is fixed in the fixing groove. It is understood that in some other embodiments, the fixing part 3331 on the housing 333 can also be other forms, as long as it can stably fix the transparent screen 31 on the housing 333 of the image projection device 33.

[0081] It is understood that in some other embodiments, a groove may be provided on the upper surface of the instrument panel 21 for mounting the image projection device 33. In some embodiments, the transparent screen 31 may be directly fixed to the instrument panel 21, for example, by means of a fixing structure.

[0082] Reference Figure 3 In this embodiment, the transparent screen 31 is generally flat, and the surface 311 of the transparent screen 31 facing the inside of the passenger compartment 10 is also generally flat. The driver's cabin 2 also includes a rotating structure 50, which drives the display device 30 to rotate, and can rotate the transparent screen 31 to face the driver's seat 41, the front passenger seat 42, or the rear seat 43. Since the surface 311 of the transparent screen 31 facing the inside of the passenger compartment 10 is flat, when the imaging film 32 is attached to the flat surface, it is easier to control the incident angle of the light projected by the P-light engine 331, thereby reducing the reflectivity of the light and reducing or avoiding the impact of ghosting on the viewing experience. Moreover, through the setting of the rotating structure 50, the driver, front passenger, and even rear passengers can all see the image information projected by the image projection device 33 onto the imaging film 32, thus effectively solving the disadvantage that a flat surface cannot meet the requirement of a wide viewing angle. In addition, since the display device 30 can rotate, the passenger compartment 10 has a strong sense of technology, which can improve the user experience.

[0083] Specifically, such as Figure 3As in the embodiment, the rotating structure 50 can be a rotatable disc-shaped structure. The housing 333 of the image projection device 33 is disposed on the rotating structure 50, and the transparent screen 31 is disposed on the housing 333 of the image projection device 33. Thus, when the rotating structure 50 drives the housing 333 of the image projection device 33 to rotate, it will not affect the relative position of the image projection device 33 and the transparent screen 31, thereby not affecting the normal projection of the image projection device 33.

[0084] It is understood that in some other embodiments, the rotating structure 50 may also be of other forms or structures, as long as it can drive the display device 30 to rotate.

[0085] In order to ensure that the image information projected by the image projection device 33 onto the imaging film 32 can be clearly seen in different scenarios, refer to Figure 3 In this embodiment, the driver's cockpit 2 also includes an angle adjustment structure 60, which is mounted on the center console 20 and connected to the transparent screen 31. The angle adjustment structure 60 is used to adjust the angle between the transparent screen 31 and the outer surface of the center console 20. Since the angle adjustment structure 60 can adjust the angle between the transparent screen 31 and the outer surface of the center console 20, such as adjusting the angle between the transparent screen 31 and the upper surface of the dashboard 21, for example, when the occupant adjusts the seat angle to a greater rearward position, the angle adjustment structure 60 can drive the transparent screen 31 to tilt forward towards the inside of the passenger compartment 10, ensuring a better relative position between the occupant and the transparent screen 31, thereby improving the viewing effect for the occupant in different postures.

[0086] like Figure 3 As shown in the embodiment, the angle adjustment structure 60 is disposed on the rotating structure 50 and connected to the housing 333 of the image projection device 33. Thus, when the angle adjustment structure 60 adjusts the angle of the transparent screen 31, the relative position of the transparent screen 31 and the image projection device 33 does not change, thereby not affecting the normal projection of the image projection device 33.

[0087] It is understood that the angle adjustment structure 60 for the transparent screen 31 and the rotation structure 50 for the transparent screen 31 in this embodiment can be automatically adjusted. For example, when the driver is sitting normally and the passenger in the front seat 42 is in a semi-reclined position, when the rotation structure 50 drives the display device 30 to rotate towards the driver, the angle adjustment structure 60 adjusts the transparent screen 31 to be nearly upright relative to its upper surface. When the rotation structure drives the display device 30 to rotate towards the passenger, the angle adjustment structure 60 adjusts the transparent screen 31 to tilt forward appropriately to ensure normal viewing for the passenger. Of course, the angle adjustment structure 60 and the rotation structure 50 can also be manually controlled to achieve the adjustment purpose.

[0088] Figure 5 for Figure 4The embodiment displays a graph showing the relationship between the reflectivity of the display device 30 and the incident angle α. The horizontal axis represents the incident angle α, and the vertical axis represents the reflectivity of the light. Figure 5 The solid line curve shows the relationship between the reflectivity of the P-light projected by the image projection device 33 and the incident angle α, while the dashed line curve shows the relationship between the reflectivity of the S-light and the incident angle α.

[0089] Reference Figure 4 and Figure 5 In this embodiment, the incident angle α of the image projection device 33 projecting onto the imaging film 32 is 25°-68°. When the incident angle α of the image projection device 33 projecting onto the imaging film 32 is within this range, the reflectivity of the P-light is much lower than that of the S-light when the incident angle α is 25°-68°. Therefore, compared to the S-light, the P-light can effectively reduce the probability of ghosting within this range, thereby reducing the impact on the passenger's viewing experience.

[0090] In some embodiments, the incident angle α of the image projection device 33 projecting onto the imaging film 32 is 50°-65°. For example... Figure 5 As shown, within this range, ghosting can be almost completely avoided, resulting in the best viewing experience.

[0091] Figure 6 This is a structural schematic diagram of another embodiment of the present application where the driver's cockpit 2 is hidden behind the passenger compartment 10. Figure 6 Same as the example Figure 3 The working principle of the display device 30 in the embodiment is the same. In addition, the transparent screen 31 is also the same. Figure 3 As in the embodiment, it is positioned in the middle of the upper surface of the instrument panel 21. Figure 6 and Figure 3 The parts that are the same as in the embodiments will not be repeated here. Figure 3 The difference in this embodiment is that, in order to ensure that the occupants in the driver's seat 41, the front passenger seat 42, and the rear seat 43 can clearly see the image information projected by the image projection device 33 onto the imaging film 32, Figure 6 In this embodiment, the surface 311 of the transparent screen 31 facing the inner side of the passenger compartment 10 is curved. The diffraction direction of the imaging film 32 on the curved surface facing the driver's seat 41 is towards the driver's seat 41, and the diffraction direction of the imaging film 32 on the curved surface facing the passenger seat 42 is towards the passenger seat 42. In this embodiment, by making the surface 311 on which the imaging film 32 is attached to the transparent screen 31 curved, the transparent screen 31 can simultaneously face the driver's seat 41, the passenger seat 42, and the rear seat 43. Therefore, the image information projected by the image projection device 33 onto the imaging film 32 on the curved surface can be clearly seen simultaneously by the occupants of the driver's seat 41, the passenger seat 42, and the rear seat 43, without requiring simultaneous viewing. Figure 3The same rotating structure 50 is added as in the embodiment to reduce the cost of the display device 30.

[0092] Figure 7 This is a structural schematic diagram of another embodiment of the present application where the driver's cockpit 2 is hidden behind the passenger compartment 10. Figure 7 Same as the example Figure 3 The working principle of the display device 30 in the embodiment is the same. In addition, the transparent screen 31 is also the same. Figure 3 As in the embodiment, it is positioned in the middle of the upper surface of the instrument panel 21. Figure 7 and Figure 3 The parts that are the same as in the embodiments will not be repeated here. Figure 3 The difference in this embodiment is that, in order to ensure that the occupants in the driver's seat 41, the front passenger seat 42, and the rear seat 43 can clearly see the image information projected by the image projection device 33 onto the imaging film 32, Figure 7 The transparent screen 31 in this embodiment includes a first plane 312 facing the driver's seat 41, a second plane 313 facing the passenger seat 42, and a curved surface 314 facing the rear seats 43. The curved surface 314 connects the first plane 312 and the second plane 313. An imaging film 32 is attached to each of the first plane 312, the second plane 313, and the curved surface 314. The diffraction direction of the imaging film 32 on the first plane 312 is towards the driver's seat 41 to ensure the driver can see the image. The diffraction direction of the imaging film 32 on the second plane 313 is towards the passenger seat 42 to ensure the passenger can see the image. The diffraction direction of the imaging film 32 on the curved surface 314 is towards the rear seats 43 to ensure the rear passengers can see the image. This eliminates the need for... Figure 3 The same rotating structure 50 is added as in the embodiment to reduce the cost of the display device 30.

[0093] The display device 30 in this application can not only be... Figure 3 , Figure 6 and Figure 7 The same implementation example is used to replace the traditional in-vehicle display, and can also be used with... Figure 8 Similar to the previous implementation, it is used to replace the traditional instrument panel in the vehicle cabin to display instrument information. For example... Figure 8 Example, Figure 8 This is a structural schematic diagram of another embodiment of the present application where the driver's cockpit 2 is hidden behind the passenger compartment 10. Figure 8 Same as the example Figure 3 The working principle of the display device 30 in the embodiment is the same. Figure 8 and Figure 3 The parts that are the same as in the embodiments will not be repeated here. Figure 3 The difference in the embodiments is that, Figure 8In this embodiment, the transparent screen 31 is positioned directly in front of the driver's cockpit 2, and the image projection device 33 projects instrument information onto the imaging film 32. Specifically, the instrument information may include at least one of the following: time, map navigation, lyrics, real-time vehicle speed, warning information, blind spot monitoring information, remaining driving range, combined battery / fuel level, tire pressure monitoring, incoming call reminders, driver status monitoring, or passenger cabin interaction information. In this embodiment, the scheme of projecting P-light onto the imaging film 32 using the P-light optical engine 331 to form image information not only reduces costs but also allows for a larger image size compared to that on the instrument panel, making it easier for the driver to view clearly. Furthermore, since the transparent screen 31 and the imaging film 32 attached to the transparent screen 31 are transparent, they do not obstruct the driver's normal field of vision.

[0094] In some other embodiments, the transparent screen 31 is the windshield 11 of the driver's cabin 2, so that the windshield 11 of the passenger cabin 10 itself can be used to attach the imaging film 32, and the effect can be achieved in any area of ​​the windshield 11, which looks very high-tech and does not take up the space under the steering wheel.

[0095] It is understood that the transparent screen 31 in this embodiment can be as follows: Figure 8 The embodiment is flat, but it can also be in other forms.

[0096] It is understood that this embodiment can also be equipped with Figure 3 The angle adjustment structure 60 in the embodiment is used to adjust the angle between the transparent screen 31 and the upper surface of the dashboard 21.

[0097] Furthermore, the display device 30 in this application can also be used to replace the host display screen, such as... Figure 9 Example, Figure 9 This is a structural schematic diagram of another embodiment of the present application where the driver's cockpit 2 is hidden behind the passenger compartment 10. Figure 9 Same as the example Figure 3 The working principle of the display device 30 in the embodiment is the same. Figure 9 and Figure 3 The parts that are the same as in the embodiments will not be repeated here. Figure 3 The difference in the embodiments is that, Figure 9In this embodiment, the transparent screen 31 is disposed on the upper surface of the dashboard 21, and extends from directly in front of the driver's seat 41 to directly in front of the passenger seat 42 in the width direction Y of the driver's cabin 2. In this embodiment, because the transparent screen 31 extends from directly in front of the driver's seat 41 to directly in front of the passenger seat 42 in the width direction Y of the driver's cabin 2, it can provide a sufficiently large size for displaying images, thereby enabling the display of more image information. For example, the display device 30 in this embodiment can be used to display one or more of the following: time, map navigation, lyrics, images, photos, temperature, humidity information, real-time vehicle speed, warning information, haptic feedback synchronization information, blind spot monitoring information, remaining driving range, combined battery / fuel level, tire pressure monitoring, incoming call reminders, caller name / number + virtual answer / hang-up buttons, personalized quotes, AR virtual pet / assistant, 3D cartoon character interaction, air quality index, driver status monitoring, or passenger cabin interaction information.

[0098] Since the transparent screen 31 has a large size in the width direction Y of the cockpit 2, in order to project different information on a split screen, the image projection device 33 includes a first image projection device 33a, a second image projection device 33b and a third image projection device 33c.

[0099] The first image projection device 33a is located on the dashboard 21 at a position corresponding to the driver's seat 41. The first image projection device 33a is used to project instrument information onto the area of ​​the imaging film 32 corresponding to the driver's seat 41. The instrument information includes at least one of the following: time, map navigation, lyrics, real-time vehicle speed, warning information, blind spot monitoring information, remaining driving range, combined battery / fuel level, tire pressure monitoring, incoming call reminder, driver status monitoring, or passenger cabin interaction information.

[0100] The second image projection device 33b is located on the dashboard 21 at a position corresponding to the passenger seat 42. The second image projection device 33b is used to project entertainment information onto the area of ​​the imaging film 32 corresponding to the passenger seat 42. The entertainment information includes at least one of the following: lyrics, images, photos, operation feedback synchronization information, and passenger cabin interaction information.

[0101] The third image projection device 33c is mounted on the dashboard 21 and is located between the first image projection device 33a and the second image projection device 33b in the width direction Y of the driver's cabin 2. The second image projection device 33b is used to project host information onto the area corresponding to the middle part of the imaging film 32 and the driver's seat 41 and the passenger seat 42. The host information includes at least one of the following: time, map navigation, lyrics, video, photos, temperature, humidity, warning information, operation feedback synchronization information, call reminder, caller's name / number + answer / hang up virtual button, personalized quotes, AR virtual pet / assistant, 3D cartoon character interaction, or air quality index and passenger cabin interaction information.

[0102] In this embodiment, the first image projection device 33a, the second image projection device 33b, and the third image projection device 33c project different image information onto the diffraction film of different areas of the transparent screen 31, respectively. This allows the driver in the driver's seat 41 to see the instrument information needed for driving, the passenger in the front passenger seat 42 to see the entertainment information, and all occupants in the passenger compartment 10 to see the host information, thereby improving the user experience. Furthermore, in this embodiment, since the transparent screen 31 extends from the position directly opposite the driver's seat 41 to the position directly opposite the front passenger seat 42 in the width direction Y of the driver's cabin 2, it is unnecessary to install a similar... Figure 3 The embodiment includes a display device 30 for replacing a traditional elf display and Figure 8 The display device 30 used to replace the instrument panel in the embodiment makes the passenger compartment 10 more integrated, and since the transparent screen 31 and the imaging film 32 are transparent, the neatness and aesthetics of the center console 20 can be effectively improved, and the overall sense of technology can be enhanced.

[0103] It is understood that in some other embodiments, only one image projection device 33 may be used, or there may be other numbers of image projection devices 33.

[0104] like Figure 9 In this embodiment, the transparent screen 31 can be set at an acute angle with the upper surface of the dashboard 21 to facilitate viewing by occupants. Of course, in other embodiments, it can also be a right angle or an obtuse angle. It is understood that this embodiment can also be combined with... Figure 3 The angle adjustment structure 60 in the embodiment is used to adjust the angle between the transparent screen 31 and the upper surface of the dashboard 21.

[0105] It is understandable that, in some other embodiments, the transparent screen 31 may also be located in the middle of the upper surface of the dashboard 21, and may be paired with a traditional dashboard or... Figure 8 The embodiment uses a display device 30 to replace the dashboard.

[0106] Figure 10 This is a structural schematic diagram of another embodiment of the present application where the driver's cockpit 2 is hidden behind the passenger compartment 10. Figure 9 Same as the example Figure 3 The working principle of the display device 30 in the embodiment is the same. Figure 10 and Figure 3 The parts that are the same as in the embodiments will not be repeated here. Figure 3 The difference in the embodiments is that, Figure 10 In this embodiment, the transparent screen 31 is disposed on the upper surface of the gear position mounting platform 22, and the transparent screen 31 is set at an angle to the upper surface of the gear position mounting platform 22.

[0107] like Figure 10 As shown in the embodiment, the transparent screen 31 is hexagonal prism in shape, and each side of the hexagonal prism is provided with an imaging film 32. The image projection device 33 can project image information onto the imaging film 32 on each side. The image information projected by the imaging film 32 on each side can be the same or different.

[0108] It is understandable that in some other embodiments, the transparent screen 31 may also be in the form of a flat plate, a cylindrical shape, or other shapes.

[0109] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
