[0037] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0038] It should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this application to those skilled in the art. In the drawings, for clarity, the dimensions and relative dimensions of layers and regions may be exaggerated. The same reference numerals denote the same elements throughout.

[0039] It should be understood that when an element or layer is referred to as "on," "adjacent to," "connected to," or "coupled to" other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, without departing from the teachings of this application, the first element, component, area, layer, or portion discussed below may be referred to as the second element, component, area, layer, or portion.

[0040] Spatial relation terms such as “below,” “under,” “below,” “under,” “above,” “above,” etc., are used herein for convenience of description to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms are intended to also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, then the element or feature described as “below” or “under” the other element or feature will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or otherwise) and the spatial descriptive terms used herein will be interpreted accordingly.

[0041] To fully understand this application, a detailed structure will be presented in the following description to illustrate the technical solutions proposed in this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0042] In related technologies, the current mainstream solution for rear-seat roof screens in vehicles is to install a ceiling-mounted display screen with a folding mechanism. When the folding mechanism is opened, the ceiling-mounted display screen unfolds and displays content, which rear-seat users can directly view. This solution only uses the ceiling-mounted display screen as a direct display application and does not develop projection capabilities for the images displayed on the ceiling-mounted display screen.

[0043] Alternatively, some solutions involve installing a projector inside the vehicle to project images directly onto the sunroof mechanism. In this solution, the image projected onto the sunroof mechanism originates from the projector itself, not from a display screen, and is not specifically designed for projection onto a ceiling-mounted display.

[0044] To address at least one of the aforementioned problems, this application provides a vehicle comprising a display screen and a projection area, wherein, in a first operating state, the display screen directly displays an image; and in a second operating state, the image displayed on the display screen is projected onto the projection area.

[0045] According to the vehicle of this application, the display screen can be used directly as an image display application, or the image displayed on the display screen can be projected onto the area to be projected, so that the area to be projected can be used as an image display application. This realizes the projection development of the image displayed on the display screen, expands the application scenarios of the display screen, and provides users with multiple scene modes for viewing images.

[0046] Example 1

[0047] The following is for reference. Figures 1-4 Describe a vehicle according to an embodiment of this application. The vehicle includes a display screen 110 and a projection area 120, wherein, in a first operating state, the display screen 110 directly displays an image, and the image displayed on the display screen 110 is directly shown to the passengers inside the vehicle; in a second operating state, the display screen 110 directly projects the displayed image onto the projection area 120, that is, the passengers inside the vehicle view the image displayed on the display screen 110 through the projection area 120.

[0048] In this embodiment, the specific installation positions of the display screen 110 and the projection area 120 within the vehicle are not limited, nor are their front-to-back positions. For example, the display screen 110 can be installed on the vehicle roof 130, and the projection area 120 can be connected to it. Alternatively, the display screen 110 can be in front and the projection area 120 in the back, or vice versa. Taking a vehicle with two rows of seats as an example, the display screen 110 and the projection area 120 can be installed in the same row or in the front and back rows respectively. When the display screen 110 and the projection area 120 are installed in the front and back rows respectively, the display screen 110 can be installed in the front row and the projection area 120 in the back row, or vice versa.

[0049] Of course, the above is only an example of a vehicle with two rows of seats. In fact, the display screen 110 and the projection area 120 of this embodiment can also be applied to vehicles with more rows of seats or even vehicles with only one row of seats. Taking the application of the display screen 110 and the projection area 120 to a vehicle with more rows of seats as an example, the display screen 110 and the projection area 120 can be set above the seats in the same row or above different rows of seats, and there is no limitation on this.

[0050] In this embodiment, the vehicle can directly use the display screen 110 as an image display application, or it can directly project the displayed image onto the projection area 120, making the projection area 120 an image display application. This enables projection development of the image displayed on the display screen 110, expands the application scenarios of the display screen 110, and provides users with multiple scene modes for viewing images.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle may also include a first motion mechanism 150, and the display screen 110 is mounted on the vehicle via the first motion mechanism 150. The first motion mechanism 150 is used to drive the display screen 110 to unfold or retract.

[0052] Specifically, the display screen 110 can be mounted on the roof 130 of the vehicle via the first motion mechanism 150. The display screen 110 can have an unfolded state and a retracted state. The retracted state of the display screen 110 means that the display screen 110 is in a horizontal or near-horizontal state, making the display screen 110 parallel or nearly parallel to the vehicle; the unfolded state of the display screen 110 means that the display screen 110 is in an upright or tilted state, making the display screen 110 perpendicular to the roof 130 or at a certain angle between the two.

[0053] When the display screen 110 is needed, the first motion mechanism 150 can drive the display screen 110 to unfold, so that the display screen 110 switches from the retracted state to the unfolded state; when the display screen 110 is not needed, the first motion mechanism 150 can drive the display screen 110 to retract, so that the display screen 110 switches from the unfolded state to the retracted state.

[0054] It is worth noting that the first motion mechanism 150 can drive the display screen 110 to deflect (with additional displacement) to unfold or retract the display screen 110. Taking a single-axis rotation mechanism as an example, the single-axis rotation mechanism can drive the display screen 110 to deflect perpendicular to the roof 130 or at a certain angle between them to unfold the display screen 110; alternatively, the single-axis rotation mechanism can also drive the display screen 110 to deflect to a near-horizontal position to retract the display screen 110. Taking a compound motion mechanism as an example, the compound motion mechanism can both drive the display screen 110 to deflect perpendicular to the roof 130 or at a certain angle between them and also drive the display screen 110 to achieve a certain displacement to unfold the display screen 110; alternatively, the compound motion mechanism can also drive the display screen 110 to deflect to a near-horizontal position and drive the display screen 110 to achieve a certain displacement to retract the display screen 110. Of course, in addition to the motion mechanisms described above, the first motion mechanism 150 can also adopt other suitable mechanisms, and this is not limited.

[0055] For example, such as Figure 1 The diagram illustrates a retracted state of the display screen 110 when it is not in use. Figure 2 The diagram shows a display screen 110 in an unfolded state when it is needed. Figure 2 In this process, the image displayed on the display screen 110 is directly projected onto the projection area 120, forming a projected image on the projection area 120. The user's eyes observe the projected image, and the projected image forms a virtual image at a distance along the user's line of sight.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle may also include an optical path calibration device 140, which is disposed on the side of the display screen 110 where the image is displayed, and is used to calibrate the light emitted by the display screen 110.

[0057] Specifically, after the display screen 110 displays an image, the light emitted by the display screen 110 can be calibrated by the optical path calibration device 140 to reduce the light emitted by the display screen 110 that directly enters the user's eyes, so as to prevent the user from directly seeing the image of the display screen 110 and thus affecting the viewing experience of the projection.

[0058] It is understood that the optical path calibration device 140 can take on various structures capable of calibrating light, and there is no limitation on this. For example, such as Figure 4As shown, the optical path calibration device 140 may include: a light-controlling glass 141 and a fixing member 142 disposed at both ends of the light-controlling glass 141. The light-controlling glass 141 is used to reduce the light emitted by the display screen 110 that directly enters the user's eyes, and the fixing member 142 is used to selectively fix or separate from the display screen 110.

[0059] Specifically, the light-controlling glass 141 and the fixing members 142 disposed at both ends can form an I-shaped structural component. The light-controlling glass 141 can be realized by attaching a light-controlling film to the glass, and the fixing members 142 can serve to block light and fix the light-controlling glass 141. Depending on the application scenario, the light-controlling glass 141 can be selectively fixedly connected to or separated from the display screen 110 through the fixing members 142 disposed at both ends. For example, when the display screen 110 is used directly for image display, the fixing members 142 are separated from the display screen 110, so that the display screen 110 is not affected by the optical path calibration device 140 and can be directly used for image display; when the projection area 120 is used for image display, the light-controlling glass 141 is selectively fixedly connected to the display screen 110 through the fixing members 142 disposed at both ends, so that when the first motion mechanism 150 drives the display screen 110 to unfold or retract, the light-controlling glass 141 can unfold or retract accordingly. It is worth noting that, regardless of the fixing method, when the display screen 110 is in the retracted state, the upper end of the fixing member 142 can be fixed to the projection mechanism 260, and the lower end of the fixing member 142 can be fixed to the display screen 110, so that the light-control glass 141 and the display screen 110 are stacked on top of each other, thereby saving interior space.

[0060] Of course, in addition to being fixedly connected to the display screen 110 in the manner described above so that it unfolds or retracts when the display screen 110 unfolds or retracts, the optical path calibration device 140 may also be disconnected from the display screen 110. The optical path calibration device 140 may have a separate motion mechanism (to distinguish it from the first motion mechanism 150, it can be called the third motion mechanism, the structure of which can be analogous to the structure of the first motion mechanism 150, and there is no limitation thereto). The optical path calibration device 140 is set on the roof 130 through the third motion mechanism, and the optical path calibration device 140 is driven to unfold or retract through the third motion mechanism so as to calibrate the light emitted by the display screen 110 when the projection area 120 is used for image display.

[0061] It is worth noting that when the display screen 110 directly projects the displayed image onto the projection area 120, the optical path calibration device 140 is also in the deployed state. The oblique light emitted by the display screen 110 is blocked by the light-controlling glass 141 and the fixing member 142, thereby reducing the light from the display screen 110 that directly enters the user's eyes and preventing the user from directly seeing the image on the display screen 110. At this time, the image displayed on the display screen 110 is inverted, which ensures that the projected image onto the projection area 120 is an upright image.

[0062] In some embodiments, the projection area 120 may include a sunroof glass disposed in the vehicle; wherein the sunroof glass has an inner surface facing the interior of the vehicle, the inner surface of the sunroof glass being used to receive the image displayed on the display screen 110.

[0063] Specifically, the image displayed on screen 110 can be directly projected onto the skylight glass, forming a magnified transparent projection image. The skylight glass can be made of PDLC, LC, or EC materials to create a switchable black background. This allows for a black projection background during projection, reducing the impact of external light and increasing projection clarity. Alternatively, ink can be applied to the projection area of ​​the skylight glass to create a fixed projection background, which also prevents interference from external light (this method cannot change the transparency of the projection area when projection is not needed, but it is less expensive).

[0064] In some embodiments, the vehicle may further include a rotating mechanism connected to the sunroof glass, which drives the sunroof glass to rotate. The rotating mechanism can be implemented as a pivot or the like, and is not limited thereto. By driving the sunroof glass to rotate through the rotating mechanism, the angle of the projected image onto the sunroof glass can be adjusted, making the angle of the projected image more vertical, allowing passengers to view the projected image in a normal sitting posture and improving the user's viewing experience. For example, Figure 3 The diagram shows how the angle of the projected image changes after the sunroof glass is rotated by a certain angle. As can be seen, the angle of the projected image becomes more vertical after the change.

[0065] In some embodiments, such as Figure 2 As shown, the projection area 120 may also include a polarizing reflective film, which is disposed on one side of the inner surface of the skylight glass; wherein, the polarizing reflective film is used to filter out useless light in the projection and reflect useful light in the projection onto the skylight glass.

[0066] Specifically, the polarizing reflective film has a first surface and a second surface, and the first surface of the polarizing reflective film can be attached to the inner surface of the skylight glass. When the projection area 120 is used for displaying an image, the light emitted by the display screen 110 is first directly projected onto the polarizing reflective film. The polarizing reflective film can filter out useless light in the light and reflect the useful light reflected from the skylight glass back onto the skylight glass, thereby improving the brightness of the projected image formed on the skylight glass.

[0067] In some embodiments, such as Figure 2 As shown, the projection area 120 may also include a liquid crystal mirror, which is disposed on one side of the inner surface of the skylight glass; wherein, the liquid crystal mirror is used to switch the polarization of the light in the projection by its own on / off state.

[0068] Liquid crystal mirrors, also known as LC mirrors, are lenses in which liquid crystal molecules can change their arrangement according to external stimuli (such as electric fields, temperature, etc.), thereby adjusting the transmission, reflection, or polarization characteristics of light.

[0069] In this embodiment, when the projection area 120 does not include a polarizing reflective film, the liquid crystal mirror can be bonded to the inner surface of the sunroof glass; when the projection area 120 includes a polarizing reflective film, the liquid crystal mirror can be bonded to the second surface of the polarizing reflective film. When the projection area 120 is used for image display, the light emitted from the display screen 110 is first projected onto the liquid crystal mirror via the projection mechanism 260. The liquid crystal mirror can be used to control the polarizing characteristics of the incident light, so that when the liquid crystal mirror is open or closed, the projection area 120 is in a high-reflection state, which can be used to improve the brightness of the projected image formed on the sunroof glass; and when the liquid crystal mirror is closed or open, the projection area 120 is in a high-transmission state, which can be used to enhance the lighting inside the vehicle and improve the brightness of the external scenery. Thus, the contrast of the projected image formed on the sunroof glass can be improved by the liquid crystal mirror.

[0070] In some embodiments, such as Figure 3 As shown, the projection area 120 may also include a free-reflecting mirror, which is slidably and rotatably disposed on one side of the inner surface of the skylight glass; wherein, the free-reflecting mirror is used to receive the image displayed on the display screen 110 instead of the skylight glass.

[0071] Specifically, the free-floating mirror can be mounted on one side of the inner surface of the sunroof glass via a sliding mechanism such as a slide rail. When the projection area 120 also includes a polarizing reflective film and / or a liquid crystal mirror, the free-floating mirror can be slidably mounted on the side of the structure facing the vehicle interior. When the projection area 120 is used for image display, the light emitted from the display screen 110 can be directly projected onto the free-floating mirror, which replaces the sunroof glass to receive the image displayed on the display screen 110, thereby forming a magnified projected image on the free-floating mirror.

[0072] In addition, the free-reflecting mirror can be connected to a rotating mechanism such as a rotating shaft, so that the free-reflecting mirror can rotate, thereby adjusting the angle of the projected image formed on the free-reflecting mirror, making the angle of the projected image more vertical, so that passengers can view the projected image in a normal sitting posture, thus improving the user's viewing experience.

[0073] Understandably, a polarizing reflective film can be added to the free-reflecting mirror to increase the brightness of the projected image formed on the free-reflecting mirror.

[0074] Of course, in some cases, after the light emitted by the display screen 110 is directly projected onto the free reflector, some light may pass through the free reflector, and this part of the light passing through the free reflector can form a projected image on the skylight glass.

[0075] In some embodiments, the free-floating mirror may be a curved mirror, a plane mirror, etc., and there is no limitation thereto.

[0076] Example 2

[0077] The following is for reference. Figures 5-10 A vehicle according to one embodiment of this application is described. The vehicle includes a display screen 210, a projection area 220, and a projection mechanism 260, wherein, in a first operating state, the display screen 210 directly displays an image; and in a second operating state, the projection mechanism 260 projects the image displayed on the display screen 210 onto the projection area 220.

[0078] In this embodiment, the specific installation positions of the display screen 210 and the projection area 220 within the vehicle are not limited, nor are their front-to-back positions. For example, the display screen 210 can be installed on the vehicle roof 230, and the projection area 220 can be connected to it. Alternatively, the display screen 210 can be in front and the projection area 220 in the back, or vice versa. Taking a vehicle with two rows of seats as an example, the display screen 210 and the projection area 220 can be installed in the same row or in the front and back rows respectively. When the display screen 210 and the projection area 220 are installed in the front and back rows respectively, the display screen 210 can be installed in the front row and the projection area 220 in the back row, or vice versa.

[0079] Of course, the above is only an example of a vehicle with two rows of seats. In fact, the display screen 210 and the projection area 220 of this embodiment can also be applied to vehicles with more rows of seats or even vehicles with only one row of seats. Taking the application of the display screen 210 and the projection area 220 to a vehicle with more rows of seats as an example, the display screen 210 and the projection area 220 can be set above the seats in the same row or above different rows of seats, and there is no limitation on this.

[0080] In this embodiment, the vehicle can either directly use the display screen 210 as an image display application, or project the image displayed on the display screen 210 onto the projection area 220, so that the projection area 220 can be used as an image display application. This enables projection development of the image displayed on the display screen 210, expands the application scenarios of the display screen 210, and provides users with multiple scene modes for viewing images.

[0081] In some embodiments, such as Figures 5-7 As shown, the vehicle may also include a first motion mechanism 250, and the display screen 210 is mounted on the vehicle via the first motion mechanism 250. The first motion mechanism 250 is used to drive the display screen 210 to unfold or retract.

[0082] Specifically, the display screen 210 can be mounted on the roof 230 of the vehicle via the first motion mechanism 250. The display screen 210 can have an unfolded state and a retracted state. The retracted state refers to the display screen 210 being in a horizontal or near-horizontal position, making it parallel or nearly parallel to the roof 230. The unfolded state refers to the display screen 210 being in an upright or tilted position, making it perpendicular to the roof 230 or at an angle between them.

[0083] When the display screen 210 is needed, the first motion mechanism 250 can drive the display screen 210 to unfold, so that the display screen 210 switches from the retracted state to the unfolded state; when the display screen 210 is not needed, the first motion mechanism 250 can drive the display screen 210 to retract, so that the display screen 210 switches from the unfolded state to the retracted state.

[0084] It is worth noting that the first motion mechanism 250 can drive the display screen 210 to deflect (with additional displacement) to unfold or retract the display screen 210. Taking a single-axis rotation mechanism as an example, the single-axis rotation mechanism can drive the display screen 210 to deflect perpendicular to the roof 230 or at a certain angle between them to unfold the display screen 210; alternatively, the single-axis rotation mechanism can also drive the display screen 210 to deflect to a near-horizontal position to retract the display screen 210. Taking a compound motion mechanism as an example, the compound motion mechanism can both drive the display screen 210 to deflect perpendicular to the roof 230 or at a certain angle between them and also drive the display screen 210 to achieve a certain displacement to unfold the display screen 210; alternatively, the compound motion mechanism can also drive the display screen 210 to deflect to a near-horizontal position and drive the display screen 210 to achieve a certain displacement to retract the display screen 210. Of course, in addition to the motion mechanisms described above, the first motion mechanism 250 can also adopt other suitable mechanisms, and this is not limited.

[0085] In some embodiments, such as Figures 5-7 As shown, the vehicle may also include a second motion mechanism 270, and the projection mechanism 260 is disposed in the vehicle via the second motion mechanism 270. The second motion mechanism 270 is used to drive the projection mechanism 260 to unfold or retract.

[0086] Specifically, the projection mechanism 260 can be mounted on the vehicle roof 230 via the second motion mechanism 270. The projection mechanism 260 can have an extended state and a retracted state. The retracted state refers to the projection mechanism 260 being in a near-horizontal horizontal position, making it parallel or nearly parallel to the vehicle roof 230. The extended state refers to the projection mechanism 260 being in an upright or tilted position, making it perpendicular to the vehicle roof 230 or at an angle to it.

[0087] When the projection mechanism 260 is needed, the second motion mechanism 270 can drive the projection mechanism 260 to unfold, so that the projection mechanism 260 switches from the retracted state to the unfolded state; when the projection mechanism 260 is not needed, the second motion mechanism 270 can drive the projection mechanism 260 to retract, so that the projection mechanism 260 switches from the unfolded state to the retracted state.

[0088] It is worth noting that the second motion mechanism 270 can drive the projection mechanism 260 to deflect (with additional displacement) to unfold or retract the projection mechanism 260. Taking a single-axis rotation mechanism as an example, the single-axis rotation mechanism can drive the projection mechanism 260 to deflect perpendicular to the roof 230 or at a certain angle between them to unfold the projection mechanism 260; alternatively, the single-axis rotation mechanism can also drive the projection mechanism 260 to deflect to a near-horizontal position to retract the projection mechanism 260. Taking a compound motion mechanism as an example, the compound motion mechanism can both drive the projection mechanism 260 to deflect perpendicular to the roof 230 or at a certain angle between them, and also drive the projection mechanism 260 to achieve a certain displacement to unfold the projection mechanism 260; alternatively, the compound motion mechanism can also drive the projection mechanism 260 to deflect to a near-horizontal position and drive the projection mechanism 260 to achieve a certain displacement to retract the projection mechanism 260. Of course, in addition to the motion mechanism described above, the second motion mechanism 270 may also adopt other suitable mechanisms, and there are no limitations on this.

[0089] In some embodiments, directly using the display screen 210 as an image display application can be considered as a first operating condition. In the first operating condition, such as... Figure 11 As shown, the first motion mechanism 250 drives the display screen 210 to the unfolded state, and the second motion mechanism 270 drives the projection mechanism 260 to the retracted state, so that the display screen 210 can work independently; using the projection area 220 as an image display application can be considered as the second working condition. In the second working condition, such as... Figure 12 Or such as Figure 13 As shown, the first motion mechanism 250 drives the display screen 210 to be in the unfolded state, and the second motion mechanism 270 drives the projection mechanism 260 to be in the unfolded state, so as to project the image displayed on the display screen 210 onto the projection area 220 through the projection mechanism 260.

[0090] In some embodiments, such as Figures 5-7 As shown, when both the projection mechanism 260 and the display screen 210 are in the retracted state, the projection mechanism 260 and the display screen 210 can be stacked vertically to save interior space.

[0091] In some embodiments, such as Figures 5-7As shown, the vehicle may also include an optical path calibration device 240, which is disposed on the side of the display screen 210 where the image is displayed, and is used to calibrate the light emitted by the display screen 210.

[0092] Specifically, after the display screen 210 displays an image, the light emitted by the display screen 210 can be calibrated by the optical path calibration device 240 to reduce the light emitted by the display screen 210 that directly enters the user's eyes, so as to prevent the user from directly seeing the image of the display screen 210 and thus affecting the viewing experience of the projection.

[0093] It is understood that the optical path calibration device 240 can take various structures capable of calibrating light, and there is no limitation on this. For example, the optical path calibration device 240 may include: a light-controlling glass and fixing members disposed at both ends of the light-controlling glass. The light-controlling glass is used to reduce the light emitted by the display screen 210 that directly enters the user's eyes, and the fixing members are used to selectively fix or separate from the display screen 210.

[0094] Specifically, the light-controlling glass and the fixing members at both ends can form an I-shaped structural component. The light-controlling glass can be achieved by attaching a light-controlling film to the glass, and the fixing members can serve to block light and fix the light-controlling glass. Depending on the application scenario, the light-controlling glass can be selectively fixedly connected to or separated from the display screen 210 through the fixing members at both ends. For example, when the display screen 210 is used directly for image display, the fixing members are separated from the display screen 210, so that the display screen 210 is not affected by the optical path calibration device 240 and can be directly used for image display. When the projection area 220 is used for image display, the light-controlling glass is selectively fixedly connected to the display screen 210 through the fixing members at both ends, so that when the first motion mechanism 250 drives the display screen 210 to unfold or retract, the light-controlling glass can unfold or retract accordingly. It is worth noting that, regardless of the fixing method, when the display screen 210 is in the retracted state, the upper end of the fixing member can be fixed to the projection mechanism 260, and the lower end of the fixing member can be fixed to the display screen 210, so that the light-control glass and the display screen 210 can be stacked one on top of the other, thereby saving interior space.

[0095] Of course, in addition to being fixedly connected to the display screen 210 in the manner described above so that it unfolds or retracts when the display screen 210 unfolds or retracts, the optical path calibration device 240 may also be disconnected from the display screen 210. The optical path calibration device 240 may have a separate motion mechanism (to distinguish it from the first motion mechanism 250 and the second motion mechanism 270, it can be called the third motion mechanism. The structure of the third motion mechanism can be analogous to the structure of the first motion mechanism 250 and the second motion mechanism 270, and there is no limitation on it). The optical path calibration device 240 is set on the roof 230 through the third motion mechanism. The third motion mechanism drives the optical path calibration device 240 to unfold or retract so as to calibrate the light emitted by the display screen 210 when the projection area 220 is used for image display.

[0096] In some embodiments, the projection mechanism 260 may include a transmissive projection mechanism 261 or a reflective projection structure. The transmissive projection mechanism 261 projects the image displayed on the screen 210 onto the projection area 220 via transmission, and the projection optical path can be as follows: Figure 8 As shown, the light emitted from the display screen 210 is projected onto the projection area 220 via the transmissive projection mechanism 261, forming a projected image on the projection area 220. The user's eye observes the projected image, which forms a virtual image at a distance along the user's line of sight. The reflective projection mechanism 132 projects the image displayed on the display screen 210 onto the projection area 220 via reflection. The projection light path can be as follows: Figure 10 As shown, the light emitted by the display screen 210 is projected onto the projection area 220 through the reflective projection mechanism 132, forming a projected image on the projection area 220. The user's eyes observe the projected image, and the projected image forms a virtual image at a distance along the user's line of sight.

[0097] It is understood that the transmissive projection mechanism 261 can have various structural components, and there is no limitation on this. For example, such as Figure 9 As shown, the transmissive projection mechanism 261 may include a first polarizer 2611, a semi-reflective freeform mirror 2612, a second polarizer 2613, a reflective polarizing film 2614, and a lens 2615 arranged sequentially and coaxially. The light emitted from the display screen 210 first passes through the first polarizer 2611, then undergoes multiple reflections between the semi-reflective freeform mirror 2612 and the reflective polarizing film 2614, and finally passes through the lens 2615 to be projected onto the projection area 220.

[0098] More specifically, the first polarizer 2611 and the second polarizer 2613 can be quarter-wave plates, etc., and the lens 2615 can be a planar transparent lens 2615, a freeform lens 2615, etc., without limitation. The transmissive projection mechanism 261 may also include a corresponding fixing structure for fixing the first polarizer 2611, the semi-reflective freeform mirror 2612, the second polarizer 2613, the reflective polarizing film 2614, and the lens 2615.

[0099] After the light emitted from the display screen 210 enters the transmissive projection mechanism 261, the light path can be as follows: Figure 6 As shown. Specifically, the light emitted from the display screen 210 (which can be calibrated first by the optical path calibration device 240 if present) first passes through the first polarizer 2611 to become right-handed circularly polarized light. The light then passes through the semi-reflective freeform mirror 2612, and then through the second polarizer 2613 to become linearly polarized light. This light in the same vibration direction is subsequently reflected back by the reflective polarizing film 2614. The reflected light passes through the second polarizer 2613 to become right-handed circularly polarized light, and then is reflected by the semi-reflective freeform mirror 2612 to become left-handed circularly polarized light. After passing through the second polarizer 2613, it becomes linearly polarized light. This linearly polarized light in the same vibration direction can pass through the reflective polarizing film 2614 and then through the lens 2615 to be projected onto the projection area 220. After the above multiple reflections, the image displayed on the display screen 210 can form a magnified projected image on the projection area 220. Generally speaking, the transmissive projection mechanism 261 of this embodiment can achieve image magnification of more than 10 times.

[0100] It is understood that reflective projection structures can have various constituent structures, and there is no limitation on this. For example, the reflective projection mechanism 132 may include a freeform surface mirror for reflecting the light emitted from the display screen 210 onto the projection area 220.

[0101] More specifically, the reflective projection mechanism 132 may also include a fixing structure for securing the freeform surface mirror.

[0102] When the image displayed on the screen 210 is projected onto the projection area 220 by the reflective projection mechanism 132, the optical path can be as follows: Figure 10 As shown. Specifically, the light emitted from the display screen 210 (which can be calibrated first by the optical path calibration device 240 if present) is incident on the freeform surface mirror. The freeform surface mirror reflects the light, projecting it onto the projection area 220 to form a magnified projected image. Generally speaking, the reflective projection mechanism 132 of this embodiment can achieve image magnification of more than 7 times.

[0103] In some embodiments, such as Figure 12 The diagram illustrates a scenario where, when the projection mechanism 260 is a transmissive projection mechanism 261, the first motion mechanism 250 drives the display screen 210 to be in an unfolded state, and the second motion mechanism 270 drives the transmissive projection mechanism 261 to be in an unfolded state. The display screen 210 and the transmissive projection mechanism 261 are parallel or nearly parallel, so that the light emitted from the display screen 210 is transmitted through the transmissive projection mechanism 261 to the projection area 220. Figure 13 The diagram shows a schematic of a projection mechanism 260 being a reflective projection mechanism 132, in which the first motion mechanism 250 drives the display screen 210 to be in an unfolded state and the second motion mechanism 270 drives the transmissive projection mechanism 261 to be in an unfolded state. The display screen 210 and the transmissive projector are in a non-parallel state so that the light emitted by the display screen 210 is reflected by the reflective projection mechanism 132 to the projection area 220.

[0104] In some embodiments, such as Figure 6 As shown, the projection area 220 may include a sunroof glass 221, which is disposed in the vehicle; wherein, the sunroof glass 221 has an inner surface facing the interior of the vehicle, and the inner surface of the sunroof glass 221 is used to receive the projection of the projection mechanism 260.

[0105] Specifically, the image displayed on the screen 210 can be projected onto the skylight glass 221 via the projection mechanism 260, thereby forming an enlarged transparent projected image on the skylight glass 221. The skylight glass 221 can be a non-PDLC skylight, a non-LC skylight, a non-EC skylight, etc.

[0106] In some embodiments, such as Figure 6 As shown, the projection area 220 may also include a polarizing reflective film 222, which is disposed on one side of the inner surface of the skylight glass 221; wherein, the polarizing reflective film 222 is used to filter out useless light in the projection and reflect useful light in the projection onto the skylight glass 221.

[0107] Specifically, the polarizing reflective film 222 has a first surface and a second surface, and the first surface of the polarizing reflective film 222 can be attached to the inner surface of the skylight glass 221. When the projection area 220 is used for displaying an image, the light emitted from the display screen 210 is first projected onto the polarizing reflective film 222 through the projection mechanism 260. The polarizing reflective film 222 can filter out useless light in the light and reflect the useful light reflected from the skylight glass 221 back onto the skylight glass 221, thereby improving the brightness of the projected image formed on the skylight glass 221.

[0108] In some embodiments, such as Figure 6As shown, the projection area 220 may also include a liquid crystal mirror 223, which is disposed on one side of the inner surface of the skylight glass 221; wherein, the liquid crystal mirror 223 is used to switch the polarization of the light in the projection by its own on / off state.

[0109] Among them, the liquid crystal mirror 223 can also be called an LC mirror. The liquid crystal molecules in the mirror can change their arrangement state according to external stimuli (such as electric field, temperature, etc.), thereby adjusting the transmission, reflection or polarization characteristics of light.

[0110] In this embodiment, when the projection area 220 does not include the polarizing reflective film 222, the liquid crystal mirror 223 can be attached to the inner surface of the sunroof glass 221; when the projection area 220 includes the polarizing reflective film 222, the liquid crystal mirror 223 can be attached to the second surface of the polarizing reflective film 222. When the projection area 220 is used for image display, the light emitted from the display screen 210 is first projected onto the liquid crystal mirror 223 via the projection mechanism 260. The liquid crystal mirror 223 can be used to control the polarizing characteristics of the incident light. When the liquid crystal mirror 223 is turned on or off, the projection area 220 is in a high-reflection state, which can be used to improve the brightness of the projected image formed on the sunroof glass 221. When the liquid crystal mirror 223 is turned off or on, the projection area 220 is in a high-transmission state, which can be used to enhance the lighting inside the vehicle and improve the brightness of the external scenery. Thus, the contrast of the projected image formed on the sunroof glass 221 can be improved by the liquid crystal mirror 223.

[0111] In some embodiments, such as Figure 7 As shown, the projection area 220 may also include a free-reflecting mirror 224, which is slidably disposed on one side of the inner surface of the skylight glass 221; wherein, the free-reflecting mirror 224 is used to replace the skylight glass 221 to receive the projection of the projection mechanism 260.

[0112] Specifically, the free-floating reflector 224 can be mounted on one side of the inner surface of the sunroof glass 221 via a sliding mechanism such as a slide rail. When the projection area 220 also includes a polarizing reflective film 222 and / or a liquid crystal mirror 223, the free-floating reflector 224 can be slidably mounted on the side of the aforementioned structure facing the vehicle interior. When the projection area 220 is used for image display, the light emitted from the display screen 210 can be projected onto the free-floating reflector 224 via the projection mechanism 260. The free-floating reflector 224 replaces the sunroof glass 221 in receiving the projection from the projection mechanism 260, thereby forming a magnified projected image on the free-floating reflector 224.

[0113] It is understandable that, in order to increase the brightness of the projected image formed on the free-reflecting mirror 224, a polarizing reflective film 222 can also be added to the free-reflecting mirror 224.

[0114] Of course, in some cases, after the light emitted by the display screen 210 is projected onto the free reflector 224 by the projection mechanism 260, some of the light may pass through the free reflector 224. This part of the light passing through the free reflector 224 can form a projected image on the skylight glass 221.

[0115] In some embodiments, the free reflector 224 may be a curved reflector, a plane reflector, etc., and there is no limitation on this.

[0116] In summary, the vehicle according to the embodiments of this application can either directly use the display screen as an image display application, or project the image displayed on the display screen onto the area to be projected through a projection mechanism, so that the area to be projected can be used as an image display application. This achieves compatibility between the area to be projected and the display screen, expands the application scenarios of the display screen, and provides users with multiple scene modes for viewing images.
