[0020] This disclosure is not limited to the embodiments shown in the accompanying drawings, but includes modifications to the configuration based on the manufacturing process. Therefore, the areas illustrated in the drawings are schematic, and the shapes of the areas shown illustrate specific shapes of the areas of an element, but are not intended to be limiting.

[0021] Reference Figure 1-4 As shown, this embodiment of the present disclosure provides a splicing screen, including a first display screen 10, a second display screen 20, and a driving device 50. The driving device 50 is used to drive at least one of the first display screen 10 and the second display screen 20 to move, so that the first display screen 10 and the second display screen 20 switch between a first state and a second state. In the first state, the display surfaces of the first display screen 10 and the second display screen 20 are at the same height and are spliced ​​together. In the second state, the display surfaces of the first display screen 10 and the second display screen 20 have a height difference.

[0022] In this application, in the first state, the first display screen 10 and the second display screen 20 are combined to display the same content, thereby increasing the display area and achieving a display effect similar to a complete large screen. By raising or lowering the first display screen 10 or the second display screen 20, the first display screen 10 and the second display screen 20 can switch between the first state and the second state. In the second state, a height difference is created between the first display screen 10 and the second display screen 20, that is, one of the first display screen 10 and the second display screen 20 is separated from the other in the display direction by a distance, which is the height difference. At this time, the two displays can be used to display different content respectively. This is especially useful in vehicle displays, where space is limited, and the number and size of the installed vehicle equipment are subject to many restrictions. However, by using the splicing screen that can switch between the first state and the second state in this application, on the basis of a large screen display effect, multiple screens can display different content to achieve more display effects.

[0023] The first display screen 10 and the second display screen 20 can be screens with only display functions or screens with touch functions. There are no restrictions on the shape, size, or flexibility of the first display screen 10 and the second display screen 20. Figure 1-2 In the embodiment shown, the first display screen 10 adopts a flat panel display screen, and as... Figure 3-4 In another embodiment shown, the first display screen 10 employs a curved display screen with a bent arc portion thereon. Furthermore, with... Figure 1-4 Taking the illustrated embodiment as an example, the second display screen 20 can protrude from the first display screen 10. To meet different needs, multiple second display screens 20 can be provided, and correspondingly, multiple driving devices 50 can also be provided. The height difference between the display surfaces of the first display screen 10 and the second display screen 20 can be set to be equal to or less than or equal to 2 cm and less than or equal to 5 cm.

[0024] The driving device 50 drives either the first display screen 10 or the second display screen 20, meaning that it can selectively drive the first display screen 10 or the second display screen 20 to move along the display direction, thereby switching the splicing screen between the first state and the second state. Alternatively, it can selectively drive the first display screen 10 or the second display screen 20 to move in a direction away from the display direction, which can also achieve the purpose of switching the splicing screen between the first state and the second state.

[0025] The specific direction of movement is not particularly restricted. Taking the second display screen 20 as an example to create a height difference with the first display screen 10, the projection position of the second display screen 20 on the first display screen 10 in the second state can completely coincide with the position of the second display screen 20 in the first state, or it can not completely coincide and have a certain distance of misalignment.

[0026] The splicing method of the first display screen 10 and the second display screen 20 in the first state can have various implementation methods. For example, the first display screen 10 and the second display screen 20 can adopt a splicing method similar to a jigsaw puzzle, or the first display screen 10 can have a hollow structure, and the second display screen 20 can be embedded in the hollow structure. The driving method of the driving device 50 can be to move either the first display screen 10 or the second display screen 20 along the display direction, or it can be to drive either the first display screen 10 or the second display screen 20 along a side opposite to the display direction, so as to achieve the purpose of switching between the first display screen 10 and the second display screen 20 in the first state and the second state. In order to achieve a better display effect and reduce the black border at the splicing point between the two display screens, both the first display screen 10 and the second display screen 20 can adopt a narrow bezel design to minimize the black border at the splicing point and achieve a better and more integrated display effect. In order for either the first display screen 10 or the second display screen 20 to be driven and moved by the driving device 50, a gap needs to be provided at the splicing point of the first display screen 10 and the second display screen 20. However, for better display effect, the gap needs to be as small as possible, and the size of the gap can be set to less than 1mm.

[0027] The driving device 50 can be a telescopic rod, a lead screw structure, or a slide rail, etc., and the driving direction is consistent with the display direction of the first display screen 10 or the second display screen 20, so that at least one of the first display screen 10 and the second display screen 20 moves in a direction perpendicular to the display surface.

[0028] As a specific implementation method, such as Figure 1-4 As shown, the first display screen 10 includes a first display module, which has a cutout portion 11 extending through its thickness direction. In a first state, the second display screen 20 is located within the cutout portion 11; in a second state, the second display screen 20 is located outside the cutout portion 11. The cutout portion 11 can be disposed within the display area of ​​the first display screen 10, and can be square, circular, elliptical, or other shapes. Figure 1-2 As shown, the cutout portion 11 is circular and is located on the lower part of the first display screen 10. The first display screen 10 needs to be sealed at the cutout portion 11 using waterproof adhesive or similar methods. Figure 9 As shown, a waterproof structure 22 is also provided at the outer edge of the second display screen 20.

[0029] Optionally, such as Figure 7-10 As shown, the first display screen 10 also includes a support layer 13 located on the side of the first display module away from its light-emitting direction. The support layer 13 has a recessed receiving portion 40 at a position corresponding to the cutout portion 11, extending away from the first display module. A driving device 50 is located in the receiving portion 40 and connected to the second display screen 20, used to drive the second display screen 20 to move in a direction perpendicular to the display surface. The support layer 13 can be a metal support component and is used to protect the first display module. The receiving portion can be integrally formed with the support layer 13, or it can be mounted on the support layer 13 by welding, snap-fitting, screwing, etc. The first display screen 10 and the second display screen 20 can have similar structures, both having a support layer. This support layer is not only used for connection to the receiving portion 40 but also for supporting and protecting the display screen. Figure 1-4 As shown, the display area and volume of the first display screen 10 are much larger than those of the second display screen 20. Based on structural strength and heat dissipation requirements, the thickness of the support layer 13 of the first display screen 10 is typically greater than the thickness of the support layer of the second display screen 20. The thickness of the support layer 13 of the first display screen 10 can be set to 0.3-1mm, and the thickness of the support layer of the second display screen 20 can be set to 0.05-0.15mm. Furthermore, for displays using flexible screens, such as… Figure 3-4 In order to satisfy the bending characteristics of the first display screen 10, its support layer 13 can be locally thinned or hollowed out.

[0030] Furthermore, such as Figure 8-11 As shown, the splicing screen also includes a touch device 30, which is fixedly connected to the second display screen 20 and located on the side of the second display screen 20 away from its light emission direction; the touch device 30 is used to receive touch commands from the user when it is started; in the first state, the touch device 30 is located in the accommodating portion 40; in the second state, at least a portion of the touch device 30 is located outside the accommodating portion 40.

[0031] In the second state, because the two display screens have a height difference, the one that protrudes above the other display screen, i.e. Figure 1-4The second display screen 20 can have a touch device 30 for user operation on the side opposite to the display direction. The touch device 30 can have various implementations, such as traditional mechanical knobs or slider-type adjustment structures. In the second state, these touch devices 30 can be exposed to the display direction of the first display screen 10, allowing the user to directly operate these structures. Compared to voice control or touch operation on a tablet screen, this provides a physical operating experience and reduces reliance on vision, allowing direct tactile operation. During operation, the user's gaze remains focused on the road conditions, thus reducing safety hazards caused by operation while driving. In addition, combined with computer software, one touch device 30 can perform the functions of multiple traditional mechanical adjustment devices. For example, when adjusting, the user can select the content being adjusted, such as volume or air conditioning temperature, while the touch device 30 only adjusts the currently displayed adjustment content.

[0032] As an optional implementation method, such as Figure 8-11 As shown, the touch device 30 includes a ring-shaped touch screen 31. The orthographic projection outline of the ring-shaped touch screen 31 on the display surface coincides with the orthographic projection outline of the second display screen 20 on the display surface, or the orthographic projection outline of the ring-shaped touch screen 31 on the display surface is located within the orthographic projection outline of the second display screen 20 on the display surface; that is, the diameter of the ring-shaped touch screen 31 is less than or equal to the diameter of the second display screen 20. More preferably, the cross-sectional shape of the ring-shaped touch screen 31 is set to be the same as that of the second display screen 20, so that the user can easily touch the ring-shaped touch screen 31 directly during operation. In addition, at least a portion of the outer peripheral surface of the ring-shaped touch screen 31 is a touch area, and in the second state it is located outside the receiving portion for user operation. The ring-shaped touch screen 31 also includes an adapter cable 32 for connecting to a control device or vehicle system, etc.

[0033] The orthographic projection outline of the circular touchscreen 31 on the display surface coincides with the orthographic projection outline of the second display screen 20 on the display surface. This means that the cross-sectional shape of the structure enclosed by the circular touchscreen 31 is consistent with the outline of the second display screen 20. The circular touchscreen 31 can be optionally set to a cylindrical shape, in which case it, together with the second display screen 20, can simulate the appearance and control experience of a mechanical knob. Since the circular touchscreen 31 is located behind the second display screen 20, a certain gap can also be provided between the circular touchscreen 31 and the second display screen 20 as needed. Users can slide and rotate the circular touchscreen 31 in the same direction with two fingers to simulate the operation of a mechanical knob. When the circular touchscreen 31 is set to a long strip shape, users can slide from one end of the circular touchscreen 31 to the other end, thus simulating the operation experience of a sliding adjustment structure. Correspondingly, setting the circular touchscreen 31 to a corresponding shape can also provide users with an operation experience similar to other adjustment devices.

[0034] Alternatively, the orthographic projection outline of the ring-shaped touch screen 31 on the display surface can be located within the orthographic projection outline of the second display screen 20 on the display surface, that is, the cross-sectional shape of the structure enclosed by the ring-shaped touch screen 31 is smaller than the outline of the second display screen 20 and is within the outline range of the second display screen 20.

[0035] Optionally, where, such as Figure 6 As shown, a first display screen 10 has a first display driver module 14 for connecting to a control device or display output device on the side opposite to the display direction. The first display screen 10 can be a touch screen. In this case, the first display screen 10 can include a first touch layer, which can be connected to the first display driver module 14 and then to the control device or display output device. The control device or display output device can be a computer host, a vehicle computer, etc.

[0036] The second display screen 20 has a second display driving module 21 on the side opposite to the display direction. Similar to the first display screen 10, the second display screen 20 can also be a touch screen. In this case, the second display screen 20 may include a second touch layer, which can be connected to a control device or a display output device through the second display driving module 21.

[0037] When there are multiple second displays 20 and circular touch screens 31, the second displays 20 and circular touch screens 31 can be set up one-to-one, but the second displays 20 and circular touch screens 31 are two relatively independent components. The circular touch screen 31 can also be connected to a control device or a display output device. The touch commands received by the circular touch screen 31 can be directly transmitted to the control device or the display output device.

[0038] In another implementation, the first display screen 10, the second display screen 20, and the circular touch screen 31 can also be connected to the same driving device, and then connected to the control device or display output device through the driving device.

[0039] When there are multiple second displays 20, multiple touch devices 30 can be provided corresponding to the second displays 20. Understandably, when there are multiple touch devices 30, these touch devices 30 can have different shapes to simulate different operating experiences. Figure 1-11 The cylindrical touch device is shown only as an example and should not be considered a limitation of this application. Users can simulate the operation of a traditional mechanical knob by touching or sliding on the touch area of ​​the circular touch screen 31 and realize the adjustment function. It should be noted that the circular touch screen 31 does not rotate or perform other actions at this time, but only recognizes the user's operation.

[0040] In addition, to further simulate the operating feel of real mechanical knobs and other adjustment devices, the touch device 30 also includes a vibration motor disposed in the space enclosed by the ring-shaped touch screen 31, which is used to provide vibration feedback when the user touches the ring-shaped touch screen 30, thereby simulating the operation of real mechanical knobs, etc.

[0041] As an optional implementation, when at least one of the first display screen 10 and the second display screen 20 receives a user input command to raise, the control device 50 drives the first display screen 10 and the second display screen 20 to move, so as to switch to the second state; when at least one of the first display screen 10 and the second display screen 20 receives a user input command to lower, the control device 50 drives the first display screen 10 and the second display screen 20 to move, so as to switch to the first state.

[0042] Furthermore, in the first state, the first display screen 10 and the second display screen 20 are linked to display the same content; in the second state, the first display screen 10 and the second display screen 20 can display independently. For example, in the second state, the first display screen 10 can display the interface of the content being adjusted, such as the volume adjustment interface or the air conditioning adjustment interface, while the second display screen 20 can display an image of a mechanical knob to further simulate the appearance of a mechanical knob.

[0043] In addition, at least one of the first display screen 10 and the second display screen 20 is a touch screen, which allows users to operate it directly by touch.

[0044] This disclosure also provides an in-vehicle display device, including the splicing screen described above. It can provide a large-screen display within the limited space inside the vehicle, while also achieving more varied display effects.

[0045] It should be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
