Description

Technical Field

[0001] This invention relates to the field of displays, and more particularly to a display device, a display device control method, and a vehicle. Background Technology

[0002] With the development of in-vehicle intelligent entertainment systems, the types and functions of in-vehicle screens are becoming increasingly diverse, such as in-vehicle ceiling screens, rear entertainment screens, and panoramic screens, which can meet passengers' audio-visual entertainment needs and enhance users' riding experience.

[0003] In related technologies, most automotive screens adopt a rigid, one-piece design, meaning the screen size is fixed. This results in a large installation space requirement, affecting the overall vehicle layout. For example, for automotive ceiling-mounted screens, they typically need to be fixed to the vehicle's ceiling with a crossbeam. Due to the large screen size (especially in the width direction), the crossbeam also needs to be designed to be large in the width direction. Whether the screen is in use or stored away, it will obstruct a large area of ​​the roof, affecting the sense of openness of the roof.

[0004] Therefore, there is an urgent need for a display device, a display device control method, and a vehicle to solve the above problems. Summary of the Invention

[0005] To address the above issues, this invention provides a display device, a display device control method, and a vehicle that can reduce the space occupied by the display device, enhance the flexibility of its use, and ensure that the maximum display size of the display device is not reduced, thereby improving the user's viewing experience.

[0006] This invention provides a display device, comprising:

[0007] Support structure;

[0008] The main structure includes a first base and a second base connected together. The end of the first base away from the second base is connected to a supporting structure, and the first base has a first unfolded position relative to the supporting structure and a first folded position folded and close to the supporting structure; the second base has a second unfolded position relative to the first base and a second folded position folded and close to the first base.

[0009] The display assembly includes a first display unit disposed on a first substrate and a second display unit disposed on a second substrate.

[0010] Based on a unified inventive concept, the present invention also provides a display device control method for controlling the display device of the present invention. The display device has multiple usage modes, and the unfolded states of the first substrate and the second substrate are different in different usage modes.

[0011] The display device control method includes the following steps:

[0012] Obtain the usage mode of the display device;

[0013] The first base is controlled to switch between a first folded position and a first unfolded position according to the usage mode, and the second base is controlled to switch between a second folded position and a second unfolded position.

[0014] Based on the same inventive concept, the present invention also provides a means of transportation, including the display device of the present invention, which is mounted on the mounting base of the means of transportation.

[0015] Compared with the prior art, the display device, display device control method, and vehicle provided by the present invention achieve at least the following beneficial effects:

[0016] The display device provided by this invention allows for the display of content through either the first or second base when in use. Specifically, the first base can be in a first unfolded position and the second base in a second folded position, or vice versa. In either case, the display device can display content using either the unfolded first or second display unit. Alternatively, both the first and second bases can be unfolded, with the first base in the first unfolded position and the second base in the second unfolded position. In this case, the display device can display content using either the first or second display unit, or both. In other words, the display device of this invention has at least two usage modes, selectable according to needs, improving the flexibility of use. Furthermore, when both the first and second bases are unfolded, the display area of ​​the device can be expanded, enhancing the user's viewing experience.

[0017] When the display device is not in use, both the first and second bases can be folded. At this time, the second display unit moves closer to the first display unit on the first base along with the second base. The first display unit then moves closer to the supporting structure along with the first base. Compared to a fixed-size display device, the display device of this invention can effectively reduce its volume through at least two folds, thereby reducing the size of the crossbeam required for installation and the installation space required, which is more conducive to the interior space layout of vehicles. For example, when the display device is applied to the roof of a vehicle, it can reduce the area obstructing the roof, enhance the sense of openness, and improve the user experience.

[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0042] like Figures 1 to 3As shown, the present invention provides a display device that can reduce the space occupied by the display device, enhance the flexibility of use of the display device, and at the same time ensure that the maximum display size of the display device is not reduced, thereby improving the user's viewing experience. The display device includes a support structure 1, a main structure 4, and a display component 2.

[0043] The main structure 4 includes a first base 41 and a second base 42 connected together. The end of the first base 41 away from the second base 42 is connected to the support structure 1. The first base 41 has a first unfolded position relative to the support structure 1 and a first folded position folded towards the support structure 1. The second base 42 has a second unfolded position relative to the first base 41 and a second folded position folded towards the first base 41. The display component 2 includes a first display unit disposed on the first base 41 and a second display unit disposed on the second base 42.

[0044] When using the display device, only the first base 41 or the second base 42 can be unfolded. That is, the first base 41 is in the first unfolded position and the second base 42 is in the second folded position, or the first base 41 is in the first folded position and the second base 42 is in the second unfolded position. In this case, the display device can display content (such as...) through the unfolded first display unit or second display unit. Figure 2 (As shown). Alternatively, both the first substrate 41 and the second substrate 42 can be unfolded, that is, the first substrate 41 is in the first unfolded position and the second substrate 42 is in the second unfolded position. In this case, the display device can display content through either the first display unit or the second display unit, or it can display content through both the first display unit and the second display unit. That is, the display device of the present invention has at least two usage modes, which can be selected according to needs, improving the flexibility of the display device. Furthermore, when both the first substrate 41 and the second substrate 42 are unfolded, the display area of ​​the display device can be expanded, enhancing the user's viewing experience.

[0045] When both the first substrate 41 and the second substrate 42 are unfolded, content can be displayed through a display unit unfolded on the same side of the first substrate 41 and the second substrate 42, or content can be displayed through display units on different sides of the first substrate 41 and the second substrate 42. For example, when only the first display unit is on the same side of the first substrate 41 and the second substrate 42, the first display unit can display content (such as...). Figure 3 (As shown); when the first display unit and the second display unit are both on the same side of the first base 41 and the second base 42, the first display unit and the second display unit can display content together. Of course, if both the first base 41 and the second base 42 are unfolded, the first display unit and the second display unit are distributed on different sides of the first base 41 and the second base 42, so that one of the first display unit and the second display unit can display content, or both of the first display unit and the second display unit can display content.

[0046] When the display device is not in use, both the first base 41 and the second base 42 can be folded. At this time, the second display unit moves closer to the first display unit on the first base 41 along with the second base 42, and the first display unit moves closer to the support structure 1 along with the first base 41 (e.g., Figure 1 As shown, compared to a fixed-size display device, the display device of the present invention can effectively reduce its volume by folding at least twice, thereby reducing the size of the crossbeam required for installing the display device, reducing the installation space required for installing the display device, and making it more conducive to the interior space layout of vehicles. For example, when the display device is applied to the roof of a vehicle, it can reduce the area obstructing the roof, enhance the sense of transparency of the roof, and improve the user experience.

[0047] In this embodiment, the first substrate 41 and the second substrate 42 can be metal frames or plastic frames. Grooves are provided on the first substrate 41 and the second substrate 42, and the first display unit and the second display unit are embedded in the corresponding grooves.

[0048] See Figure 2 When the first substrate 41 or the second substrate 42 is unfolded, the second display unit and the first display unit can be selectively operated. That is, when only the first substrate 41 or the second substrate 42 is unfolded, the display is made through the display unit on the surface of the first substrate 41 or the second substrate 42. The display surface of the first display unit can face the user, or the display surface of the second display unit can face the user. At this time, by controlling the corresponding first display unit or second display unit to operate, the display device can display content through the first display unit or the second display unit, realizing small-screen viewing.

[0049] See Figure 3 When both the first substrate 41 and the second substrate 42 are unfolded, both the first display unit and the second display unit can operate. That is, when both the first substrate 41 and the second substrate 42 are unfolded, the display is performed through the display unit on the same side of the first substrate 41 and the second substrate 42. For example, if the first display unit is located on the side of the first substrate 41 and the second substrate 42 facing the user, and the second display unit is located on the back, then the first display unit is controlled to operate and display content, while the second display unit may not operate. If both the first display unit and the second display unit are located on the same side of the first substrate 41 and the second substrate 42 and facing the user, then both the first display unit and the second display unit are controlled to operate, enabling the display device to display content through the first display unit or through both the first display unit and the second display unit, achieving large-screen viewing and improving the user's viewing experience.

[0050] Optionally, see Figure 4 , Figure 5 and Figure 7The display device also includes a rotating assembly 3. Both the first base 41 and the second base 42 are connected to the rotating assembly 3. The second base 42 can switch between a second unfolded position and a first unfolded position under the drive of the rotating assembly 3. That is, by driving the second base 42 relative to the first base 41 to fold and unfold, the rotating assembly 3 enables the display device to be folded and stored, and also enables the display device to be unfolded into different states for display.

[0051] See Figure 5 , Figure 6 and Figure 7 The rotating assembly 3 includes a first mounting bracket 31, a second mounting bracket 32, and a driving component 33. The first mounting bracket 31 is connected to the first base 41, the second mounting bracket 32 ​​is connected to the first mounting bracket 31, and the second base 42 is connected to the second mounting bracket 32. The driving component 33 is disposed on the first mounting bracket 31, and its output end is electrically connected to the second mounting bracket 32, used to drive the second mounting bracket 32 ​​to rotate the second base 42 relative to the first base 41. In this embodiment, the second mounting bracket 32 ​​is rotatably connected to the first mounting bracket 31. When the second base 42 needs to be unfolded, the driving component 33 is activated, causing the second mounting bracket 32 ​​to rotate relative to the first mounting bracket 31. The second display unit then unfolds or folds relative to the first display unit along with the second base 42, enabling either the first or second display unit to be displayed individually, or the first and second display units to be displayed synchronously.

[0052] For example, the drive element 33 can be a brushless motor, which can achieve precise speed and torque control. The brushless motor is small in size and can be integrated on the first mounting bracket 31. In other embodiments, the drive element 33 can also be a micro servo motor, as long as it can drive the second mounting bracket 32 ​​to rotate the second base 42 relative to the first base 41.

[0053] Optionally, see Figure 7 The rotating component 3 also includes a transmission structure 34, which comprises multiple transmission gear sets 341 and an output shaft 342. The output end of the drive component 33 is connected to the first transmission gear set 341 among the multiple transmission gear sets 341, one end of the output shaft 342 is connected to the last transmission gear set 341 among the multiple transmission gear sets 341, and the other end of the output shaft 342 is connected to the second mounting bracket 32. The drive component 33 is connected to the output shaft 342 through multiple transmission gear sets 341, which can achieve multi-stage speed reduction. While ensuring transmission efficiency, the structure is more compact and smaller in size. Furthermore, the arrangement of multiple transmission gear sets 341 can increase the output torque of the output shaft 342, so that the second base 42 can be smoothly unfolded or folded relative to the first base 41 at a suitable speed, avoiding damage to the display component 2 and improving the stability of unfolding and folding actions.

[0054] For example, three transmission gear sets 341 are provided, enabling the output shaft 342 to achieve three-stage reduction, ensuring that the output torque of the output shaft 342 is sufficiently large, and ensuring the stability of the second base 42 relative to the first base 41 during unfolding and folding. In other embodiments, two or more transmission gear sets 341 may be provided. In specific design, the number of transmission gear sets 341 can be adaptively selected according to factors such as the unfolding and folding speed requirements and load-bearing capacity requirements of the second base 42, and is not limited to the number of transmission gear sets 341 listed above.

[0055] Optionally, the second substrate 42 has multiple second unfolded positions, and the unfolding angle of the second substrate 42 relative to the first substrate 41 is different in different second unfolded positions. This configuration allows the user to adjust the unfolding angle of the second substrate 42 according to actual needs, placing the second display unit at different display angles to meet various usage requirements. Figure 8 As shown, the second substrate 42 can unfold relative to the first substrate 41 by less than 90 degrees. Figure 9 As shown, the second substrate 42 can also be unfolded relative to the first substrate 41 by more than 90 degrees but less than 180 degrees. For example... Figure 10 As shown, the second substrate 42 can also be unfolded approximately 180 degrees relative to the first substrate 41. Of course, the second substrate 42 can also be unfolded 180 degrees relative to the first substrate 41, as... Figure 3 As shown.

[0056] See Figure 7 A damping element 35 is provided on the output shaft 342, and the second base 42 can be held in different second unfolded positions under the action of the damping element 35. That is, the presence of the damping element 35 allows the second base 42 to hover and stably maintain its current position when unfolded at different angles relative to the first base 41, so that the second display unit or the first display unit can display content at different unfolded angles.

[0057] For example, the damping element 35 may be an adaptive damper, which is sleeved on the output shaft 342 and allows the output shaft 342 to be suspended at any angle.

[0058] Optionally, an angle detection element is provided on the output shaft 342 to detect the rotation angle of the output shaft 342. When the output shaft 342 drives the second substrate 42 to rotate relative to the first substrate 41, the angle detection element monitors the rotation angle of the output shaft 342 in real time, thus monitoring the unfolding angle of the second substrate 42. After the user selects the unfolding angle of the second substrate 42, the drive unit 33 drives the output shaft 342 to rotate. When the rotation angle measured by the angle detection element reaches the unfolding angle selected by the user, the drive unit 33 stops, thus keeping the second display unit at the user-selected display angle, making the control more intelligent.

[0059] For example, the angle detection element is a high-precision encoder. In other embodiments, the angle detection element can also be a rotation sensor or the like, as long as it meets the angle detection requirements.

[0060] Optionally, see Figure 5 , Figure 6 and Figure 7 The first mounting frame 31 includes a mounting housing and a first connecting portion 311 disposed within the mounting housing. The driving component 33 and the transmission structure 34 are both located within the mounting housing, and the first connecting portion 311 is connected to the first base 41. Placing moving parts such as the driving component 33 and the transmission structure 34 within the mounting housing makes the exterior of the rotating assembly 3 neater and safer during folding and unfolding. When the driving component 33 drives the output shaft 342 to rotate, the mounting housing and the first base 41 remain stationary. The output shaft 342 drives the second mounting frame 32 to rotate relative to the mounting housing, thereby causing the second base 42 to rotate and unfold or fold relative to the first base 41.

[0061] In this embodiment, the mounting housing is cylindrical, the drive component 33 is fixed inside the cylindrical mounting housing, and the output shaft 342 is coaxially arranged inside the mounting housing. Multiple transmission gear sets 341 of the transmission structure 34 are sequentially arranged axially between the drive component 33 and the output shaft 342. The structure is compact, reducing the overall volume of the rotating assembly 3. In other embodiments, the mounting housing can also be of other shapes, as long as it can accommodate or fix components such as the drive component 33 and the transmission structure 34. The shape of the mounting housing is not limited here.

[0062] Optionally, the first connecting part 311 is a first connecting ear that is fixedly connected to the mounting housing. The first connecting ear and the first base 41 can be fixed by fasteners such as screws, or the first connecting ear can also be glued to the first base 41.

[0063] For example, two first connecting portions 311 are provided at intervals on the mounting housing to enhance the connection stability between the first mounting bracket 31 and the first base 41. In other embodiments, the number of first connecting portions 311 can be set according to actual needs, and is not limited to the number listed above.

[0064] See Figure 7 The second mounting bracket 32 ​​includes a rotating part 321 and a connecting part 322 connected together. The rotating part 321 is electrically connected to the output end of the driving member 33, and the second connecting part 322 is connected to the second base 42. In this embodiment, the rotating part 321 is connected to the output shaft 342 of the transmission structure 34. When the driving member 33 drives the output shaft 342 to rotate, the output shaft 342 drives the rotating part 321 to rotate, causing the second base 42 to rotate and unfold or fold relative to the first base 41.

[0065] Optionally, the second connecting part 322 is a second connecting ear that is fixedly connected to the rotating part 321. The second connecting ear and the second base 42 can be fixed by fasteners such as screws, or the second connecting ear can also be glued to the second base 42.

[0066] For example, two second mounting brackets 32 are provided, and the rotating parts 321 of the two second mounting brackets 32 are respectively rotatably connected to the two ends of the mounting housing. Both second connecting parts 322 are connected to the second base 42, which can enhance the stability of the rotational connection between the second base 42 and the first base 41.

[0067] Optionally, see Figure 1 and Figure 2 The support structure 1 is provided with a receiving groove 11. When the first base 41 is in the first folded position and the second base 42 is in the second folded position, both the first display unit and the second display unit are located in the receiving groove 11. This arrangement allows the first base 41 and the second base 42 to be embedded in the receiving groove 11 when both are folded, that is, the entire display device is embedded in the receiving groove 11, making storage neater and more aesthetically pleasing.

[0068] Optionally, the support structure 1 includes a crossbeam and a decorative panel. The crossbeam is mounted on the mounting base, and the decorative panel is connected to the crossbeam and has a receiving groove 11. The crossbeam provides a mounting base for the decorative panel and the display device. The decorative panel can be used to embed the display device, ensuring stable and reliable installation of the display device while also considering aesthetics.

[0069] For example, when the display device is applied to a vehicle, the mounting base can be the roof inside the vehicle, with the crossbeam fixed to the roof. When both the first base 41 and the second base 42 are folded, the entire display device is embedded in the decorative panel receiving groove 11, making the roof more flat and aesthetically pleasing.

[0070] Optionally, see Figure 2 and combined Figure 4The display device also includes a connecting shaft 5, through which the first base 41 is connected to the support structure 1. In this embodiment, the first base 41 is rotatably connected to the support structure 1 via the connecting shaft 5, so as to realize the rotational folding and unfolding of the first base 41 relative to the support structure 1. For example, two rotating slots can be provided on the support structure 1, and the connecting shaft 5 is fixedly connected to the first base 41. The two ends of the connecting shaft 5 are rotatably engaged with the two rotating slots one-to-one, so that the first base 41 can rotate relative to the support structure 1.

[0071] In other embodiments, a drive motor can be provided on the support structure 1. The output end of the drive motor is connected to the connecting shaft 5. The drive motor drives the connecting shaft 5 to rotate the first base 41 relative to the support structure 1, thereby realizing the electric control of the first base 41 to unfold and fold.

[0072] Optionally, a multi-stage transmission gear can be provided between the output end of the drive motor and the connecting shaft 5 to make the first base 41 unfold and fold more smoothly. Furthermore, an adaptive damper can be provided on the connecting shaft 5 so that the connecting shaft 5 can rotate at different angles, so that when the first base 41 unfolds at different angles, the second base 42 can be suspended and stably maintained at the current position.

[0073] The display device provided by the present invention includes a display component 2. Optionally, see [reference needed]. Figure 2 , Figure 3 and Figure 4 The display component 2 includes a first display screen 21 and a second display screen 22. The first display screen 21 is a first display unit, disposed on the same side of the first substrate 41 and the second substrate 42. The second display screen 22 is a second display unit, disposed on the second substrate 42, and located on the side opposite to the first display screen 21. Figure 2 As shown, when the first base 41 is in the first unfolded position and the second base 42 is in the second folded position, the display surface of the second display screen 22 faces the user, and corresponding content can be displayed by illuminating the second display screen 22. Figure 3 As shown, when both the first substrate 41 and the second substrate 42 are unfolded, the display surface of the first display screen 21 faces the user, and the corresponding content can be displayed by turning on the first display screen 21.

[0074] Optionally, the first display screen 21 can be a flexible display screen, and the second display screen 22 can be a rigid display screen or a flexible display screen. That is, the first display screen 21 can be folded or unfolded with the movement of the first substrate 41 and the second substrate 42. Since the second display screen 22 is on the side of the second substrate 42 opposite to the first display screen 21, the second display screen 22 does not need to be folded, so a rigid display screen or a flexible display screen can be used.

[0075] See Figure 1 and Figure 2 When the first base 41 is in the first folded position and the second base 42 is in the second folded position, the second display unit is located on the side of the first display unit facing the support structure 1. That is, the second base 42 is folded inside the first base 41. When a small-screen display is needed, the first base 41 is unfolded relative to the support structure 1, so that the display surface of the second display screen 22 faces the user, and the second display screen 22 can be controlled to display the corresponding content. When a large-screen display is needed, the second base 42 is unfolded relative to the first base 41 again, so that the display surface of the first display screen 21 faces the user, and the first display screen 21 can be controlled to display the corresponding content on a large screen. At this time, the second display screen 22 can be inactive.

[0076] Optionally, refer to Figure 2 In the orientation of the middle, the first base 41 is rotatably connected to the rear side of the receiving groove 11 via the connecting shaft 5.

[0077] Optionally, please refer to Figure 5 The display component 2 includes a third display screen 23, which includes a first display section 231 and a second display section 232 connected together. The first display section 231 is a first display unit, and the second display section 232 is a second display unit. The first display section 231 and the second display section 232 are located on the same side of the first substrate 41 and the second substrate 42. When the second substrate 42 rotates relative to the first substrate 41, the third display screen 23 folds or unfolds accordingly to achieve small-screen or large-screen display.

[0078] Optionally, the third display screen 23 can be a flexible display screen, allowing the first display section 231 and the second display section 232 to be folded and unfolded relative to each other.

[0079] Optionally, such as Figure 5 As shown, the third display screen 23 is bonded and fixed to the first substrate 41 and the second substrate 42 using structural adhesive 6.

[0080] In some embodiments, when the first base 41 is in the first folded position and the second base 42 is in the second folded position, the second display unit is located on the side of the first display unit facing the support structure 1. That is, the second base 42 is folded inside the first base 41, and the second display part 232 of the third display screen 23 rotates and folds clockwise around the output pivot 342. In this case, the second display part 232 can be designed as a double-sided display screen. When a small screen display is required, the first base 41 is unfolded relative to the support structure 1, and the side of the second display part 232 facing away from the first display part 231 faces the user, controlling the content displayed on the side of the second display part 232 facing away from the first display part 231. When a large screen display is required, the second base 42 is unfolded relative to the first base 41 again, so that the content is displayed on the same side of the first display part 231 and the second display part 232.

[0081] In some embodiments, the design can also be such that when the first base 41 is in the first folded position and the second base 42 is in the second folded position, the second display unit is located on the side of the first display unit facing away from the support structure 1. That is, the second base 42 is folded outside the first base 41, and the second display part 232 of the third display screen 23 rotates and folds counterclockwise around the output pivot 342. When a small screen display is required, only the first base 41 (or only the second base 42) can be unfolded, allowing the first display part 231 (or the second display part 232) to display content. When a large screen display is required, the second base 42 (first base 41) is unfolded again, allowing the first display part 231 and the second display part 232 to display content simultaneously.

[0082] Optionally, see Figure 11 The display component 2 includes a fourth display screen 24 and a fifth display screen 25. The fourth display screen 24 is a first display unit, and the fifth display screen 25 is a second display unit. The fourth display screen 24 and the fifth display screen 25 are located on the same side of the first substrate 41 and the second substrate 42. When both the first substrate 41 and the second substrate 42 are unfolded, the fourth display screen 24 and the fifth display screen 25 are spliced ​​together to form a large screen, thereby realizing a large-screen display.

[0083] For example, the second base 42 is rotated and folded counterclockwise relative to the first base 41 around the output shaft 342. When the first base 41 is in the first folded position and the second base 42 is in the second folded position, the fifth display screen 25 is located on the side of the fourth display screen 24 facing away from the support structure 1. At this time, when only the first base 41 or the second base 42 is unfolded, the display surface of the fourth display screen 24 or the fifth display screen 25 faces the user, enabling small-screen display.

[0084] Optionally, the fourth display screen 24 is bonded to the first substrate 41 by structural adhesive 6, and the fifth display screen 25 is bonded to the second substrate 42 by structural adhesive 6.

[0085] Optionally, the fourth display screen 24 is a rigid display screen or a flexible display screen. The fifth display screen 25 is a rigid display screen or a flexible display screen.

[0086] In some embodiments, the fourth display screen 24 and the fifth display screen 25 can both be rigid display screens, such as liquid crystal displays. When the first substrate 41 and the second substrate 42 are both unfolded, the fourth display screen 24 and the fifth display screen 25 are spliced ​​together. Through splicing screen control technology, the fourth display screen 24 and the fifth display screen 25 can display the same image together, ensuring that the display area of ​​the display component 2 is large enough.

[0087] In some embodiments, the fourth display screen 24 and the fifth display screen 25 can both be rigid or flexible displays. Micro LED technology can be used to process the fourth display screen 24 and the fifth display screen 25 so that neither of them has a black border. When the first substrate 41 and the second substrate 42 are both unfolded, there is no black border between the fourth display screen 24 and the fifth display screen 25, which can ensure the display size and display effect of the display device.

[0088] The present invention also provides a display device control method for controlling the display device as described above. The display device has multiple usage modes, and the first substrate 41 and the second substrate 42 have different unfolding states in different usage modes.

[0089] The display device control method includes the following steps:

[0090] S1. Obtain the usage mode of the display device;

[0091] S2. Control the first base 41 to switch between the first folded position and the first unfolded position according to the usage mode, and control the second base 42 to switch between the second folded position and the second unfolded position.

[0092] When using the display device, users can select the usage mode according to their needs. Once the usage mode is determined, they can control the first substrate 41 or the second substrate 42 to unfold individually to achieve a small screen display, or control both the first substrate 41 and the second substrate 42 to unfold to achieve a large screen display, thus meeting the different viewing needs of users.

[0093] In step S2, the second base 42 is unfolded or folded relative to the first base 41 by the drive component 33 of the rotating assembly 3, and the first base 41 is unfolded or folded relative to the support structure 1 by the drive motor. Alternatively, the first base 41 can be unfolded or folded manually.

[0094] Optionally, the display device has at least a first usage mode and a second usage mode. When the user selects the first usage mode, one of the first substrate 41 and the second substrate 42 unfolds, allowing one of the first display unit and the second display unit to operate. When the user selects the second usage mode, both the first substrate 41 and the second substrate 42 unfold, allowing both the first display unit and the second display unit to operate.

[0095] For example, Figure 2 and Figure 4In the display device, when the first base 41 is in the first folded position and the second base 42 is in the second folded position, the second display screen 22 is located on the side of the first display screen 21 facing the support structure 1. In the first usage mode, the first base 41 is unfolded relative to the support structure 1, so that the display surface of the second display screen 22 faces the user, and controlling the second display screen 22 to operate can realize small-screen display. In the second usage mode, in Figure 2 Based on this, the second substrate 42 is unfolded relative to the first substrate 41, such as Figure 3 As shown, the display surface of the first display screen 21 faces the user. By controlling the first display screen 21 to operate, the corresponding content can be displayed on the large screen. At this time, the second display screen 22 located behind the first display screen 21 can be inactive.

[0096] When display component 2 adopts Figure 5 In the structure shown, in the first usage mode, only the first base 41 (or only the second base 42) can be unfolded, allowing the first display unit 231 (or the second display unit 232) to display content. In the second usage mode, both the first base 41 and the second base 42 are unfolded, allowing the first display unit 231 and the second display unit 232 to display content simultaneously.

[0097] The present invention also provides a means of transportation, including the display device as described above, which is mounted on a mounting base of the means of transportation. The means of transportation may be a car, train, airplane, etc., and the display device may be installed inside the means of transportation as needed.

[0098] For example, when a display device is used in a car, it can be mounted on the roof, in which case the roof is the mounting base. Alternatively, the display device can be mounted behind the car seat, in which case the car seat is the mounting base.

[0099] When vehicles adopt the aforementioned display devices, users can choose the usage mode of the display devices according to their needs, realizing small-screen or large-screen display, improving the viewing experience. Furthermore, since the display devices can be folded, they can reduce the space occupied, achieving a reasonable layout of the vehicle's interior space.

[0100] As can be seen from the above embodiments, the display device, display device control method, and vehicle provided by the present invention achieve at least the following beneficial effects:

[0101] The display device provided by the present invention includes: a support structure 1; a main body structure 4, including a first base 41 and a second base 42 connected together, wherein the end of the first base 41 away from the second base 42 is connected to the support structure 1, and the first base 41 has a first unfolded position relative to the support structure 1 and a first folded position folded towards the support structure 1; the second base 42 has a second unfolded position relative to the first base 41 and a second folded position folded towards the first base 41; and a display component 2, including a first display unit disposed on the first base 41 and a second display unit disposed on the second base 42. When using the display device, the present invention can unfold only the first base 41 or the second base 42, that is, the first base 41 is in the first unfolded position and the second base 42 is in the second folded position, or the first base 41 is in the first folded position and the second base 42 is in the second unfolded position. In this case, the display device can display content through the unfolded first display unit or the second display unit. Alternatively, both the first substrate 41 and the second substrate 42 can be unfolded, i.e., the first substrate 41 is in a first unfolded position and the second substrate 42 is in a second unfolded position. In this case, the display device can display content through either the first display unit or the second display unit, or it can display content through both the first display unit and the second display unit. That is, the display device of the present invention has at least two usage modes, which can be selected according to needs, improving the flexibility of the display device. Furthermore, when both the first substrate 41 and the second substrate 42 are unfolded, the display area of ​​the display device can be expanded, enhancing the user's viewing experience.

[0102] When the display device is not in use, both the first base 41 and the second base 42 can be folded. At this time, the second display unit moves closer to the first display unit on the first base 41 along with the second base 42. The first display unit moves closer to the support structure 1 along with the first base 41. Compared to a fixed-size display device, the display device of this invention can effectively reduce its volume through at least two folds, thereby reducing the size of the crossbeam required for installation and the installation space required, which is more conducive to the interior space layout of vehicles. For example, when the display device is applied to the roof of a vehicle, it can reduce the area obstructing the roof, enhance the sense of openness of the roof, and improve the user experience.
