DETAILED DESCRIPTION

[0047] Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some of these specific details. The description of the embodiments is merely to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least some well-known structures and techniques are not shown in order to avoid unnecessary obscuring of the present application; and, for clarity, the dimensions of some structures can be exaggerated. In addition, features, structures or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0048] In the description of the present application, it should be noted that, unless otherwise specified, the meaning of "a plurality of" is more than two; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like are merely for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0050] like Figures 1 to 2 As shown, a display module provided by an embodiment of the present application includes: a box body 100, a connecting component 200 and a panel component 300; the connecting component 200 is arranged on the box body 100, and the connecting component 200 includes two or more elastic members 210 arranged at intervals; the panel component 300 is connected to the connecting component 200, and the panel component 300 includes at least two sub-panels 310, each sub-panel 310 is connected to the side of each elastic member 210 away from the box body 100, and the elastic member 210 can be deformed along a thickness direction X perpendicular to the display module so that the sub-panel 310 can be moved along the thickness direction X perpendicular to the display module.

[0051] In this embodiment, the panel assembly 300 is mounted on one side of the housing 100 in the thickness direction X via the connecting assembly 200. The connecting assembly 200 includes two or more elastic members 210, and each sub-panel 310 is connected to the housing 100 via the elastic member 210. The elastic member 210 is deformable along the thickness direction X perpendicular to the display module, thereby allowing the sub-panel 310 connected to the elastic member 210 to move along the thickness direction X perpendicular to the display module. The sub-panels 310 are arranged side by side along the thickness direction X perpendicular to the display module to form a spliced ​​display panel. The gap between two adjacent sub-panels 310 is small, making it difficult to disassemble and assemble. When a target sub-panel 310 is damaged and needs to be disassembled, the sub-panel 310 adjacent to the target sub-panel 310 is moved along the thickness direction X perpendicular to the display module away from the target sub-panel 310 to increase the gap, thereby facilitating the disassembly and assembly of the target sub-panel 310 and improving the performance of the display module.

[0052] It is understandable that the elastic member 210 is deformed with the side connected to the box body 100 as the base point along the thickness direction X perpendicular to the display module, thereby causing the sub-panel 310 connected to the side of the elastic member 210 away from the box body 100 to move along the thickness direction X perpendicular to the display module.

[0053] like Figure 3As shown, in some optional embodiments, the display module also includes at least two electromagnetic parts 220 arranged in the box body 100, each electromagnetic part 220 is arranged between each sub-panel 310 and the box body 100, and each sub-panel 310 is provided with a magnetic body 320 on the side facing the box body 100. The electromagnetic parts 220 and the magnetic bodies 320 are arranged in a one-to-one correspondence, and the magnetic force of the electromagnetic parts 220 is variable so that the sub-panel 310 can be switched between the installation state 20 and the pop-up state 10; in the installation state 20, the sub-panel 310 is adsorbed on the box body 100 by the electromagnetic part 220; in the pop-up state 10, the sub-panel 310 pops out in the direction away from the box body 100.

[0054] In these optional embodiments, an electromagnetic portion 220 is provided between each sub-panel 310 and the housing 100. The electromagnetic portion 220 is magnetic when energized, and the magnitude of the magnetism can be controlled by the strength of the current, and the magnetic pole can be controlled by changing the direction of the current. The magnetic force of the electromagnetic portion 220 is variable, and a magnetic body 320 is provided on the side of each sub-panel 310 facing the housing 100. The electromagnetic portion 220 and the magnetic body 320 are provided in a one-to-one correspondence so that the sub-panel 310 can be transformed between the installed state 20 and the pop-up state 10. In the installed state 20, the magnetic body 320 provided on the sub-panel 310 is adsorbed on the housing 100 by the electromagnetic portion 220. When the sub-panel 310 is transformed from the installed state 20 to the pop-up state 10, the sub-panel 310 pops out in a direction away from the housing 100.

[0055] Optionally, the display module includes multiple electromagnetic parts 220, which are arranged on the side of the box 100 facing the sub-panel 310. Each sub-panel 310 corresponds to at least two electromagnetic parts 220, and the electromagnetic parts 220 are arranged symmetrically along the center of the sub-panel 310 to ensure that the magnetic force exerted on the sub-panel 310 is uniform.

[0056] Optionally, the magnetic body 320 includes a ferromagnetic material, which may include iron, cobalt, nickel, etc.

[0057] Optionally, each sub-panel 310 is a rectangular structure. The rectangular sub-panel 310 corresponds to four electromagnetic parts 220 , and each electromagnetic part 220 is located at four corners of the sub-panel 310 .

[0058] Optionally, the housing 100 has a receiving space, the connecting assembly 200 is disposed in the receiving space, and the housing has an opening communicating with the receiving space on one side facing the sub-panel 310. In the installed state 20, the connecting assembly 200 is located in the receiving space, which helps to ensure the integrity of the display module appearance.

[0059] like Figure 3 As shown, in some optional embodiments, the sub-panel 310 is in the installed state 20 and the elastic member 210 is in a compressed state.

[0060] In these optional embodiments, the sub-panel 310 is attracted by the electromagnetic portion 220 in the installed state 20, and the elastic member 210 is in a compressed state. Optionally, when the magnetic attraction force of the electromagnetic portion 220 is less than the restoring force of the elastic member 210, the restoring force of the elastic member 210 is directed away from the housing 100, thereby causing the sub-panel 310 to pop out in a direction away from the housing 100.

[0061] like Figure 4 As shown, in some optional embodiments, the magnetic body 320 includes a first magnet 321 , and in the installed state 20 , the first magnet 321 and the electromagnetic portion 220 are attracted to each other.

[0062] In these optional embodiments, in the installed state 20, the electromagnetic portion 220 and the first magnet 321 are mutually attracted. Optionally, the electromagnetic portion 220 and the first magnet 321 are disposed opposite each other along the thickness direction X of the display module. The first magnet 321 is disposed on the side of the sub-panel 310 facing the housing 100. In the installed state 20, the first magnet 321 and the electromagnetic portion 220 are disposed in contact with each other.

[0063] Optionally, the first magnet 321 and the electromagnetic portion 220 are spaced apart along the thickness direction X of the display module. It is understandable that the first magnet 321 and the electromagnetic portion 220 are spaced apart and still have magnetic force. When the first magnet 321 and the electromagnetic portion 220 are spaced apart, when the sub-panel 310 moves in the direction perpendicular to the thickness direction X of the display module, no friction occurs between the first magnet 321 and the electromagnetic portion 220, thereby reducing the friction force when the sub-panel 310 moves in the direction perpendicular to the thickness direction X of the display module and improving the flexibility of the sub-panel 310.

[0064] Optionally, in the pop-up state 10, the electromagnetic portion 220 and the first magnet 321 repel each other. The electromagnetic portion 220 can change the magnetic polarity by changing the direction of the current, thereby causing the electromagnetic portion 220 and the first magnet 321 to shift from mutual attraction to mutual repulsion. The repulsive force between the electromagnetic portion 220 and the first magnet 321 can cause the sub-panel 310 to pop out away from the housing 100. The elastic member 210 and the electromagnetic portion 220 work together to shift the sub-panel 310 into the pop-up state 10. If the elastic member 210 is insufficiently elastic, the repulsive force of the electromagnetic portion 220 shifts the sub-panel 310 into the pop-up state 10, thereby increasing the reliability of the display module.

[0065] Optionally, the first magnet 321 is a permanent magnet.

[0066] like Figure 5As shown in some optional embodiments, the display module further comprises a second magnet 230 arranged on the box 100, and the sub-panel 310 further comprises a third magnet 322 arranged on the side of the box 100. In the installation state 20, the first magnet 321 and the electromagnetic part 220 are attracted to each other, and the third magnet 322 and the second magnet 230 are attracted to each other.

[0067] In these optional embodiments, the second magnet 230 is arranged on the box 100, the first magnet 321 and the electromagnetic part 220 are arranged opposite to each other along the thickness direction X of the display module, and the third magnet 322 and the second magnet 230 are arranged opposite to each other along the thickness direction X of the display module. In the installation state 20, the first magnet 321 and the electromagnetic part 220 are attracted to each other, and the third magnet 322 and the second magnet 230 are attracted to each other. When the electromagnetic part 220 is powered off, the electromagnetic part 220 does not generate magnetism, and the sub-panel 310 can be kept in the installation state 20 by the third magnet 322 and the second magnet 230 being attracted to each other, thereby preventing the sub-panel 310 from being ejected by the elastic member 210.

[0068] In the installation state 20, the third magnet 322 and the second magnet 230 are attracted to each other, which can reduce the attraction force of the electromagnetic part 220, thereby reducing the power consumption of the display module. Optionally, in the installation state 20, the attraction force between the third magnet 322 and the second magnet 230 is greater than or equal to the restoring force of the elastic member 210, and the attraction force between the electromagnetic part 220 and the first magnet 321 can be 0.

[0069] Optionally, in the ejection state 10, the magnetic attraction force between the first magnet 321 and the electromagnetic part 220 and the magnetic attraction force between the third magnet 322 and the second magnet 230 are less than the elastic restoring force.

[0070] When the magnetic attraction force between the first magnet 321 and the electromagnetic part 220 and the magnetic attraction force between the third magnet 322 and the second magnet 230 are less than the restoring force of the elastic member 210, the sub-panel 310 is ejected by the restoring force of the elastic member 210.

[0071] Alternatively, in the ejection state 10, the first magnet 321 and the electromagnetic part 220 are repulsive, and the sum of the repulsive force and the restoring force of the elastic member 210 is greater than the magnetic attraction force between the third magnet 322 and the second magnet 230, thereby causing the sub-panel 310 to be ejected by the repulsive force between the first magnet 321 and the electromagnetic part 220 and the restoring force of the elastic member 210.

[0072] As shown in some optional embodiments, the plurality of first magnets 321 are arranged in a central symmetry with respect to the sub-panel 310. Figure 6 and Figure 7 As shown in some optional embodiments, the plurality of first magnets 321 are arranged in a central symmetry with respect to the sub-panel 310.

[0073] In these optional embodiments, the first magnets 321 are centrally symmetrically distributed relative to the sub-panel 310, so that the magnetic attraction force on the sub-panel 310 is more uniform.

[0074] It can be understood that the electromagnet and the second magnet 230 arranged opposite to the first magnet 321 are both centrally symmetrically distributed relative to the sub-panel 310.

[0075] Optionally, the third magnets 322 are centrally symmetrically distributed relative to the sub-panel 310. Since the magnetic force between the first magnets 321 and the electromagnet 220 is not equal to the magnetic force between the third magnets 322 and the second magnet 230, and the magnetic force between the first magnets 321 and the electromagnet 220 is not equal to the magnetic force between the third magnets 322 and the second magnet 230 during the mutual conversion between the mounted state 20 and the ejected state 10, when the first magnets 321 are centrally symmetrically distributed relative to the sub-panel 310 and the third magnets 322 are centrally symmetrically distributed relative to the sub-panel 310, the magnetic force on the sub-panel 310 is more uniform.

[0076] Optionally, as shown in Figure 6 , the sub-panel 310 includes a middle part 311 and a plurality of side parts 312 arranged around the middle part 311, and the first magnets 321 and the third magnets 322 are arranged on the side parts 312. Arranging the first magnets 321 and the third magnets 322 on the side parts 312 leaves the middle part 311 of the sub-panel 310, so that components such as connecting wires can be arranged in the middle part 311. Arranging the first magnets 321 and the third magnets 322 on the side parts 312 can support the side parts 312, preventing the sub-panel 310 from being inwardly recessed into the box body 100 from the edges of the sub-panel 310 when the sub-panel 310 is mounted.

[0077] Optionally, as shown in Figure 7 , a corner part 313 is connected between two adjacent side parts 312, and the first magnets 321 and the third magnets 322 can be arranged on the corner parts 313. Each corner part 313 is correspondingly provided with at least one first magnet 321 or third magnet 322.

[0078] Optionally, as shown in Figure 7 , the sub-panel 310 has a rectangular structure, and the sub-panel 310 includes four corner parts 313. Two corner parts 313 opposite along one diagonal are respectively provided with the first magnets 321, and two corner parts 313 opposite along the other diagonal are respectively provided with the third magnets 322.

[0079] As shown in Figure 8 and Figure 9 , in some optional embodiments, the connecting assembly 200 includes a plurality of elastic members 210, and the plurality of elastic members 210 are centrally symmetrically distributed relative to the sub-panel 310.

[0080] In these optional embodiments, the elastic members 210 are distributed centrally and symmetrically with respect to the sub-panel 310 , so that the restoring force exerted on the sub-panel 310 can be more uniform.

[0081] Optional, such as Figure 8 As shown, the sub-panel 310 includes a middle portion 311 and a plurality of side portions 312 disposed around the middle portion 311. The elastic member 210 is disposed on the side portions 312. The elastic member 210 is disposed on the side portions 312, leaving the middle portion 311 of the sub-panel 310 free, thereby allowing components such as connecting wires to be disposed in the middle portion 311. Furthermore, the elastic member 210 disposed on the side portions 312 provides support for the side portions 312, preventing the edges of the sub-panel 310 from sinking into the interior of the box 100 when the sub-panel 310 is installed.

[0082] Optional, such as Figure 9 As shown, a corner portion 313 is connected between two adjacent side portions 312 , and each corner portion 313 is correspondingly provided with at least one elastic member 210 .

[0083] Optional, such as Figure 10 As shown, the display module further includes a support portion 400 , which is disposed on a side of the box body 100 facing the sub-panel 310 . The support portion 400 is used to support the sub-panel 310 , and each corner portion 313 is correspondingly provided with at least one support portion 400 .

[0084] The support portion 400 is provided on a side of the box body 100 facing the sub-panel 310 for supporting the sub-panel 310 . The support portion 400 supports the corner portion 313 of the sub-panel 310 to prevent the corner portion 313 of the sub-panel 310 from sinking into the interior of the box body 100 when the sub-panel 310 is installed.

[0085] like Figure 11 As shown, in some optional embodiments, a first connecting portion 240 is provided on the side of the box body 100 facing the sub-panel 310, and a second connecting portion 250 is provided on the side of the sub-panel 310 facing the box body 100. The first connecting portion 240 and the second connecting portion 250 are arranged opposite to each other along the thickness direction X, and the two ends of the elastic member 210 are respectively connected to the first connecting portion 240 and the second connecting portion 250.

[0086] In these optional embodiments, the first connecting portion 240 and the second connecting portion 250 are oppositely arranged in the thickness direction X of the display module, and the elastic member 210 is connected to the first connecting portion 240 and the second connecting portion 250 at two ends thereof, respectively, and extends along the thickness direction X of the display module. Optionally, the first connecting portion 240 and the second connecting portion 250 are annular grooves, and the elastic member 210 is sleeved in the first connecting portion 240 and the second connecting portion 250 at two ends thereof, respectively; or the first connecting portion 240 and the second connecting portion 250 are circular protrusions, and the elastic member 210 is sleeved out of the first connecting portion 240 and the second connecting portion 250 at two ends thereof, respectively. The first connecting portion 240 and the second connecting portion 250 are used to fix the position of the elastic member 210 on the sub-panel 310 and the box body 100, so as to ensure that the elastic member 210 can be elongated or compressed along the thickness direction X of the display module in the mounted state 20 and the popped-out state 10, and when the spring is deformed in a direction perpendicular to the thickness direction X of the display module, the elastic member 210 is sleeved out of the first connecting portion 240 and the second connecting portion 250 at two ends thereof, respectively, or the elastic member 210 is sleeved in the first connecting portion 240 and the second connecting portion 250 at two ends thereof, respectively, so as to ensure that the elastic member 210 does not deviate from the box body 100 or the sub-panel 310, and the connection reliability of the elastic member 210 is enhanced.

[0087] As shown in Figure 12 some optional embodiments, the sub-panel 310 includes a screen body 314 and a protective layer 315 arranged in layers, and the orthographic projection of the screen body 314 along the thickness direction X of the display module is located within the orthographic projection of the protective layer 315 along the thickness direction X of the display module.

[0088] In these optional embodiments, the sub-panel 310 includes a screen body 314 and a protective layer 315 arranged in layers, and the orthographic projection of the screen body 314 along the thickness direction X of the display module is located within the orthographic projection of the protective layer 315 along the thickness direction X of the display module, so that when the sub-panels are spliced and switched between the popped-out state 10 and the mounted state 20, the abutting portion between the two adjacent sub-panels 310 is located at the protective layer 315, so that the screen bodies 314 between the two adjacent sub-panels 310 can be prevented from colliding with each other. Optionally, the protective layer 315 is arranged on the side of the screen body 314 facing the box body 100; or the protective layer 315 is arranged on the side of the screen body 314 away from the box body 100.

[0089] As shown in Figure 13 some optional embodiments, the sub-panel 310 includes a screen body 314 and a guide portion 316 arranged in layers, and the guide portion 316 is arranged on the side of the screen body 314 facing the box body 100. The guide portion 316 is provided with an inclined portion 317 on the side facing the box body 100, and the size of the cross section of the inclined portion 317 gradually decreases in the direction close to the box body 100.

[0090] In the optional embodiments, the guide portion 316 is arranged on the side of the screen body 314 facing the box body 100, and the guide portion 316 is provided with an inclined portion 317 facing the box body 100. The inclined portion 317 functions as a guide, wherein the size of the cross section of the inclined portion 317 gradually decreases in the direction away from the box body 100 and in the direction away from the box body 100. During the process of changing the sub-panel 310 from the pop-up state 10 to the installation state 20, the sub-panel 310 is moved towards the side of the box body 100. Since the sub-panel 310 is connected to the box body 100 by the elastic member 210, and the elastic member 210 can be deformed in the direction perpendicular to the thickness direction X of the display module, the sub-panel 310 can be offset to a certain extent during the movement towards the box body 100. The inclined portion 317 of the guide portion 316 can function as a guide during the installation of the sub-panel 310. When the inclined portion 317 abuts against the adjacent sub-panel 310, the inclined portion 317 continues to move towards the direction close to the box body 100, so that the screen body 314 moves towards the direction opposite to the installation position. The arrangement of the guide portion 316 is beneficial to the installation of the sub-panel 310 to the correct position and prevents the collision between the sub-panels 310.

[0091] Optionally, the orthographic projection of the screen body 314 along the thickness direction X of the display module is located in the orthographic projection of the guide portion 316 along the thickness direction X of the display module. Therefore, during the splicing of the sub-panels and the switching between the pop-up state 10 and the installation state 20, the abutment between the adjacent two sub-panels 310 is located in the guide portion 316, so that the collision between the screen bodies 314 of the adjacent two sub-panels 310 can be prevented.
