[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] In the related art, the display screens configured in vehicles mostly use liquid crystal display screens or LED display screens, which can not only be used to display vehicle status information, but also to realize audio-visual entertainment functions and information interaction functions. However, due to the limitation of the space inside the car, the distance between the display screen and the user is relatively close, resulting in a short viewing distance, and the occupants are prone to fatigue when watching the display screen. This problem is particularly prominent when there are more and more in-vehicle screens and their sizes are getting larger and larger.

[0033] In order to solve the above technical problems, an embodiment of the present disclosure provides a display device and a vehicle, wherein the display device is arranged in the vehicle, and the installation position of the display device is higher than the height of a seat of the vehicle, and the display device includes: an imaging unit and an image source; the imaging unit is used to reflect image light emitted by the image source into an observation area; the imaging unit is located between a virtual image formed by the image light emitted by the image source through the imaging unit and the observation area.

[0034] The imaging unit can be used to reflect image light to an observation area, which can also be called an eye box. When the user's eyes are located in the area, the image light can be received and a virtual image can be seen. The height of the installation position of the display device is higher than the height of the vehicle seat, so that the user can view the virtual image at a more comfortable viewing angle.

[0035] Compared with LCD screens and LED screens, in the display device provided in the embodiment of the present disclosure, the imaging part is located between the virtual image and the observation area. The distance between the virtual image viewed by the virtual user and the user can break through the space limitations of the vehicle itself and reach a distance that is more comfortable for the user to watch, making the user's eyes more comfortable and less prone to fatigue, which helps to improve viewing comfort.

[0036] The display device and vehicle provided in the embodiments of the present disclosure are exemplarily described below in conjunction with the accompanying drawings.

[0037] The embodiment of the present disclosure provides a display device, which is arranged in a vehicle, and the height of the installation position of the display device is higher than the height of the seat of the vehicle. Figure 1-5 As shown, the display device includes: an imaging unit 20 and an image source 10; the imaging unit 20 is used to reflect the image light emitted by the image source 10 into the observation area 30; the imaging unit 20 is located between the virtual image 10′ formed by the image light emitted by the image source 10 through the imaging unit 20 and the observation area 30.

[0038] The display device is arranged in the vehicle to provide image display services to users, and the users include at least one of the driver, the co-driver and the rear passenger. Correspondingly, the observation area 30 includes at least one of the main driver's seat area, the co-driver's seat area and the rear seat area. Optionally, the observation area 30 includes the upper part of each seat area, corresponding to the eye area or the head area of ​​the seat occupant.

[0039] The imaging unit 20 of the display device is an independent imaging component, which is independent of the windshield and is used to receive the image light emitted by the image source 10 and reflect the image light so that the user can see the virtual image 10'. The area where the imaging unit 20 reflects the image light emitted by the image source 10 is the observation area 30, so that the user in the observation area 30 can see the virtual image 10'. The imaging unit 20 can be transparent or opaque.

[0040] The height of the seat may be the height of the seat surface or the height of the upper end of the seat (e.g., the uppermost end of the seat), and the height of the installation position of the imaging unit 20 is higher than the height of the seat. Figure 1 ), the sun visor in front of the co-pilot (as shown Figure 3 as shown) or ceiling (as Figure 4-5 The imaging unit 20 may also be installed on the upper end of the windshield, the upper end of the front seat backrest or the window glass, which is not limited here. In this way, the user can view the virtual image 10' at a horizontal or upward viewing angle, avoiding problems such as cervical discomfort caused by lowering the head.

[0041] Optionally, the angle between the line connecting the center of the virtual image 10' and the center of the observation area 30 and the reference plane is greater than or equal to 0°; wherein the reference plane includes one of a horizontal plane and a road surface on which the vehicle is located. If the line is located above the reference plane, the angle is positive; if the line is located below the reference plane, the angle is negative.

[0042] The angle between the line connecting the center of the virtual image 10′ and the center of the observation area 30 and the reference plane is equal to 0°, that is, the user views the virtual image 10′ at a level perspective; the angle between the line connecting the center of the virtual image 10′ and the center of the observation area 30 and the reference plane is greater than 0°, that is, the user views the virtual image 10′ at an upward perspective; this arrangement avoids problems such as cervical discomfort caused by the user lowering his head to view the display screen.

[0043] Alternatively, in some examples, the virtual image 10 ′ may be a downward viewing angle, but in order to make the user's viewing more comfortable, the downward viewing angle is less than 0° and greater than or equal to −6°.

[0044] It should be noted that the embodiments of the present disclosure only exemplarily illustrate that the display device is disposed at positions such as the sun visor, the roof, the upper end of the windshield, the front seat back, and the window glass, but does not constitute a limitation on the display device provided by the embodiments of the present disclosure. In other embodiments, the display device can be disposed at any appropriate position in the vehicle, which is not limited here.

[0045] In the related art, for in-vehicle screens such as LCD or LED screens, the user's viewing distance is equal to the distance between the screen and the observation area (i.e., the user's eyes). Due to the limited space in the vehicle, the installation location of these screens cannot be too far away from the user, especially for rear passengers. Users are prone to fatigue when watching the screen at a close distance.

[0046] In this embodiment, the image source 10 is used to emit image light, and the image light is transmitted to the imaging unit 20 along a set optical path. The imaging unit 20 reflects the image light into the observation area 30, so that the user can view the image in the observation area 30. The virtual image 10′ formed by the image light emitted by the image source 10 through the imaging unit 20 is located on the side of the imaging unit 20 away from the observation area 30. The viewing distance of the user is equal to the imaging distance between the virtual image 10′ and the observation area 30. The imaging distance between the virtual image 10′ and the observation area 30 can break through the space limitation of the vehicle itself and reach a distance that is more comfortable for the user to watch. The user's eyes are more comfortable and less prone to fatigue, which helps to improve viewing comfort.

[0047] For example, Figure 2 As shown, the image light emitted by the image source 10 is reflected by the imaging unit 20 into the observation area 30, and a virtual image 10′ is formed on the side of the imaging unit 20 away from the observation area; wherein, the distance between the image source 10 and the imaging unit 20 is L1, the distance between the virtual image 10′ and the imaging unit 20 is L2, and the distance between the imaging unit 20 and the observation area 30 is L3; the viewing distance of the user is equal to the imaging distance between the virtual image 10′ and the observation area 30, that is, the viewing distance is equal to the sum of L2 and L3. Compared with the LCD screen and the LED screen, the distance between the virtual image 10′ and the user is increased, so that the distance between the virtual image viewed by the user and the user can break through the space limitation of the vehicle itself and reach a distance that is more comfortable for the user to watch, so that the user's eyes are more comfortable and less prone to fatigue, which helps to improve viewing comfort.

[0048] The display device provided by the embodiment of the present disclosure is arranged in a vehicle, and the height of the installation position of the display device is higher than the height of the vehicle seat. Compared with the LCD screen and the LED screen, the display device increases the distance between the virtual image 10′ and the user. The distance between the virtual image viewed by the user and the user can break through the space limitation of the vehicle itself and reach a distance that is more comfortable for the user to watch, making the user's eyes more comfortable and less prone to fatigue, which helps to improve viewing comfort.

[0049] In some embodiments, the viewing area is provided for viewing of the virtual image by at least one non-driver user within the vehicle.

[0050] Among them, non-driver users are users other than the driver in the vehicle, including at least one of the co-driver and the rear passenger. Correspondingly, the observation area includes at least one of the main driver's seat area, the co-driver's seat area, and the rear seat area. For example, Figure 3 As shown, the imaging unit 20 of the display device is installed on the sun visor in front of the co-pilot, and the viewing area 30 includes the co-pilot seat area for the co-pilot to view the virtual image 10'. Figure 4As shown, the imaging unit 20 is installed on the roof of the vehicle, and the viewing area 30 includes a rear seat area for rear passengers to view the virtual image 10 ′.

[0051] In some optional embodiments, a corresponding display device may be configured for each seat in the vehicle, and the viewing area of ​​the display device corresponds to the seat. Alternatively, some seats share the same display device, and the viewing area of ​​the display device covers at least part of the shared seat.

[0052] In some embodiments, Figure 1-5 As shown, the display device further includes: a mounting portion; the mounting portion is used to mount the imaging portion 20 at at least one position on a sun visor, a ceiling, a windshield, a vehicle window glass, and a front seat back.

[0053] The imaging unit 20 is an independent display component, including but not limited to an imaging plate and an imaging window, and also includes all imaging components known to those skilled in the art, which are not limited here. The imaging unit 20 can be transparent or opaque.

[0054] Among them, the mounting portion is used to fix the imaging portion 20 at a set mounting position. The embodiment of the present disclosure does not limit the type of the mounting portion, and all components with a fixing function known to those skilled in the art can be selected. For example, the mounting portion may include a double-sided adhesive layer, and the imaging portion 20 is adhered to the set mounting position by utilizing the strong adhesion of the double-sided adhesive layer. Alternatively, the mounting portion may also include a connecting mechanism, such as screws and nuts, to connect the imaging portion 20 to the component at the set mounting position. The mounting position of the imaging portion 20 includes a sun visor, a roof, a windshield, a car window glass, and at least one position on the front seat back.

[0055] In some embodiments, the mounting portion includes: a moving mechanism; the moving mechanism is used to control the movement of the imaging portion 20 to achieve the deployment of the imaging portion 20 when in use and the folding of the imaging portion 20 when not in use.

[0056] Among them, when the user is not using the display device, the moving mechanism controls the imaging part to be folded up to reduce the occupied space; when the user needs to use the display device, the moving mechanism controls the imaging part to be unfolded, and the display surface of the imaging part 20 faces the observation area 30, and the user can view the virtual image 10′ through the imaging part 20. For example, the moving mechanism includes a rotating shaft. When the user is not using the display device, the imaging part 20 is made parallel to the sun visor, windshield or ceiling by rotating the rotating shaft to reduce the occupied space in the cabin; when the user needs to use the display device, the display surface of the imaging part 20 is made to face the observation area 30 by rotating the rotating shaft, that is, there is a certain angle between the imaging part 20 and the sun visor, windshield or ceiling. For example, Figure 4-5As shown, the imaging unit 20 is installed on the ceiling. When the display device is not in use, the imaging unit 20 is parallel to the ceiling. When the display device is in use, the display surface of the imaging unit 20 is facing the observation area 30. The imaging unit 20 may not be perpendicular to the ceiling (including tilted forward or backward), and may also be perpendicular to the ceiling.

[0057] In some embodiments, the field angle of view (FOV) of the display device ranges from 5° to 25°; and / or the imaging distance between the virtual image and the observation area ranges from 2m to 50m.

[0058] In this embodiment, the field of view FOV of the display device is the angle of the maximum range of the virtual image 10' that can be observed in the observation area 30, and the field of view FOV includes a horizontal field of view angle and a vertical field of view angle. The angle between the line connecting the upper boundary of the virtual image 10' and the center of the observation area 30 and the line connecting the lower boundary of the virtual image 10' and the center of the observation area 30 is the vertical field of view angle. The angle between the line connecting the left boundary of the virtual image 10' and the center of the observation area 30 and the line connecting the right boundary of the virtual image 10' and the center of the observation area 30 is the horizontal field of view angle. The horizontal field of view FOV of the display device has a value range of 5° to 25°. For example, the field of view FOV is set to 5°, 10°, 15° or 20°, etc. Preferably, the field of view angle is 10°. A larger field of view FOV can achieve a larger screen size, which is conducive to increasing the user's sense of immersion.

[0059] The viewing distance is equal to the imaging distance between the virtual image 10 ′ and the observation area 30 , and the imaging distance ranges from 2 m to 50 m; for example, the imaging distance is 2 m, 5 m, 10 m, 15 m, 20 m or 25 m.

[0060] Combination Figure 1-5 , the field of view FOV of the display device is related to the imaging distance and the size of the virtual image 10'. When the imaging distance is fixed, the field of view FOV is positively correlated with the size of the virtual image 10'. The larger the size of the virtual image 10', the larger the corresponding field of view FOV; when the size of the virtual image 10' is fixed, the field of view FOV is inversely proportional to the imaging distance. The larger the imaging distance, the smaller the field of view FOV. The imaging distance and the size of the virtual image are both related to the installation position and the size of the image source 10. By designing the installation position of the image source 10 (i.e., determining the distance between the image source 10 and the imaging unit 20) and the size of the image source, the display device can achieve the expected field of view FOV.

[0061] In some embodiments, Figure 5 As shown, the display device further includes: a reflection unit 40 ; the reflection unit 40 is used to reflect the image light emitted by the image source 10 to the imaging unit 20 .

[0062] The reflecting part 40 is disposed in the optical path between the image source 10 and the imaging part 20, and is used to reflect the image light emitted by the image source 10 to the imaging part 20, and the imaging part 20 reflects the image light into the observation area 30. The purpose of adding the reflecting part 40 in the optical path is to fold the optical path, and reduce the distance between the image source 10 and the imaging part 20 while ensuring that the optical path meets the imaging requirements.

[0063] The reflective portion 40 may be transparent, opaque, or translucent, which is not limited herein. Exemplarily, the reflective portion 40 is translucent and can selectively transmit light of a certain characteristic wavelength, for example, the reflective portion 40 can transmit infrared rays.

[0064] In some embodiments, Figure 6 FIG. 1 is a schematic diagram of a structure of a display device provided by an embodiment of the present disclosure. Figure 6 In the display device, the image source 10 includes at least a first display area 11 and a second display area 12, the optical path of the image light transmitted from the first display area 11 to the imaging portion 20 is a first optical path, and the optical path of the image light transmitted from the second display area 12 to the imaging portion 20 is a second optical path, and the first optical path is greater than the second optical path to form at least two virtual images with different imaging distances.

[0065] The virtual images at different imaging distances may at least partially overlap in the direction of the line of sight, or may not overlap, which is not limited here. For example, in the case of non-overlap, information such as instant messaging and phone notifications may be displayed on the near layer, and audio and video content may be displayed on the far layer, but it is not limited thereto.

[0066] For example, Figure 6 As shown, in the display device, the image source 10 includes a first display area 11 and a second display area 12, the optical path of the image light transmitted from the first display area 11 to the imaging unit 20 is the first optical path, and the image light emitted from the first display area 11 forms a first virtual image 11′ through the imaging unit 20; the optical path of the image light transmitted from the second display area 12 to the imaging unit 20 is the second optical path, and the image light emitted from the second display area 12 forms a second virtual image 12′ through the imaging unit 20. This arrangement realizes multi-level imaging and meets more diverse usage requirements.

[0067] It should be noted that Figure 6It is only exemplarily shown that by setting a first reflector 41 in the optical path between the first display area 11 and the imaging unit 20, and setting a second reflector 42 in the optical path between the second display area 12 and the imaging unit 20, the first reflector 41 corresponds to the first display area 11, and the second reflector 42 corresponds to the second display area 12, the optical paths of the image light emitted from different display areas are different, thereby achieving imaging at different distances, but it does not constitute a limitation on the display device provided by the embodiment of the present disclosure. In other embodiments, other methods can also be used to achieve different optical paths from different display areas to the imaging unit, such as setting a medium part with different refractive index in the optical path, which is not limited here.

[0068] It should be noted that Figure 6 The image source 10 is shown to include two display areas, and two virtual images with different imaging distances are formed accordingly, but it does not constitute a limitation on the display device provided in the embodiment of the present disclosure. In other embodiments, the image source 10 may include more display areas or include multiple image sources 10 to form a corresponding number of virtual images, which is not limited here.

[0069] In some embodiments, the display device also includes: a directional speaker; the directional speaker is configured in a one-to-one correspondence with the display device; the directional speaker is used to direct the sound emitted by the directional speaker to the corresponding target area to avoid mutual interference of the sounds; wherein the target area includes the observation area of ​​the display device.

[0070] In the related art, when multiple display devices are installed in a vehicle, when the multiple display devices are used at the same time, it will cause sound interference between the display devices, and it is also easy to affect the driver's safe driving of the vehicle.

[0071] In this embodiment, a directional speaker is configured for each display device, and the directional speaker propagates the sound to the target area corresponding to the display device, so that users in the target area can hear the sound, thereby avoiding sound interference between different display devices. The target area at least includes the viewing area of ​​the display device, and users at different positions within the target area can all hear the sound emitted by the speaker.

[0072] The sound propagation direction of the directional speaker is basically the same as the direction of the imaging part toward the observation area; for example, taking a display device located in the middle of the ceiling as an example, the display device is used to provide image display services to rear passengers, and the observation area includes the rear seat area. The imaging part of the display device faces the rear of the car, and the directional speaker configured for the display device propagates the sound toward the rear of the car, avoiding interference with the display device set at the front of the car. When multiple display devices are set in the back row, the target areas of the directional speakers of different display devices do not overlap to avoid interference.

[0073] In some embodiments, the display device further includes: a common speaker; at least part of the display device in the vehicle is connected to the common speaker; and the common speaker is used to propagate the sound emitted by the common speaker to at least part of the target area in the vehicle.

[0074] In this embodiment, the display device further includes a common speaker, and when the display images of at least two display devices in the vehicle are the same, the sound can be propagated to the target areas of the at least two display devices through the common speaker. For example, when users in different seats in the vehicle use different display devices to watch the same movie or the same program, the sound can be propagated to the target areas corresponding to the display devices through the common speaker, so that users in different target areas can hear the sound.

[0075] It should be noted that the public speaker and the directional speaker can be independent audio devices or the same audio device. The audio device includes at least two working modes: directional propagation and public playback. The corresponding working mode can be selected according to the content played by the display device, which is not limited here.

[0076] It should be noted that the application scenario of the display device provided by the embodiment of the present disclosure is not limited to vehicles, but can also be applied to other means of transportation, such as airplanes, ferries, and high-speed railways, etc., which are not limited here.

[0077] On the basis of the above-mentioned implementation manner, the embodiment of the present disclosure further provides a vehicle, including: any one of the above-mentioned display devices, which has corresponding beneficial effects and is not limited here to avoid repeated description.

[0078] The vehicle includes, but is not limited to, electric vehicles, fuel vehicles, and hybrid vehicles, and also includes all types of vehicles known to those skilled in the art, which are not limited here. In other embodiments, the vehicle also includes all combined components or on-board equipment known to those skilled in the art, such as sun visors, audio systems, and laser radars, which are not limited here.

[0079] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0080] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
