[0066] A video wall display device is composed of multiple display modules spliced ​​together. In some products, the display modules are mounted on a cabinet and include a display substrate and a bracket supporting the display substrate. Currently, when splicing display modules, each display module is usually connected to the cabinet along its thickness direction. This splicing method is inconvenient, and when splicing to form a video wall display device with narrow seams, adjacent display modules are prone to collisions and other problems.

[0067] This disclosure provides a mounting structure for a display module. The display module includes a mounting structure and at least one display substrate disposed on the mounting structure. The display substrate can be a light-emitting diode (LED) display substrate, which includes a substrate and a plurality of light-emitting elements disposed on the substrate. The substrate can be a glass substrate, and the light-emitting elements can be Mini-LED devices or Micro-LED devices. The mounting structure provided in this disclosure is used to mount the entire display module on a mounting bracket.

[0068] like Figure 1 , Figure 2A , Figure 2B , Figure 8 , Figure 9 As shown, the mounting structure 100 of the display module 1 includes: a support frame 130, an adapter plate 110, a guide member 140, a sliding member 13a, and a mounting member 120. It has a support surface and a mounting surface arranged opposite to each other, the support surface being used to support at least one display substrate 200. The adapter plate 110 is disposed on the side of the mounting surface away from the support surface, the adapter plate 110 is connected to the support frame 130, and the adapter plate 110 is movable relative to the support frame 130 in a direction parallel to the support surface. Figure 3 and Figure 7 As shown, the guide member 140 is disposed on the side of the adapter plate 110 facing the support frame 130 and includes a slide rail 14a. The guide member 140 is configured to rotate about a preset axis perpendicular to the support surface, thereby switching between at least two guiding states, such that the extension direction of the slide rail 14a switches between at least two preset directions parallel to the support surface. For example, the preset axis passes through the guide member 140, such as... Figure 7 As shown, when the mounting structure 100 is in an upright state, the guide member 140 can be rotated to switch between three guiding states. In the first guiding state, as... Figure 7 As shown in Figure (a), slide 14a tilts to the left, forming a "\" shape; in the second guiding state, as... Figure 7 As shown in Figure (b), slide 14a extends along the height direction of mounting structure 100; in the third guide state, as... Figure 7 As shown in Figure (c), slide 14a is tilted to the right, forming a " / " shape.

[0069] Figure 7The guiding state of the guide member 140 is only an example. In actual applications, the guide member 149 can switch between two guiding states, three guiding states, or more guiding states.

[0070] like Figure 2A As shown, the sliding member 13a is fixedly connected to the support frame 130 and slidably mounted on the slide rail 14a. The slide rail 14a can be a recessed groove or a protruding slide rail. The mounting member 120 is located on the side of the adapter plate 110 away from the support frame 130 and is used to connect with the adapter plate 110 and the mounting bracket 500.

[0071] like Figure 11 As shown, taking a splicing display device comprising three rows of display modules 1, each row of display modules 1 mounted on a mounting bracket 500 as an example, when splicing the three rows of display modules 1, for the middle row of display modules 1, when assembling each display module 1 with the mounting bracket 500, the mounting component 120 can be fixed to the mounting bracket 500 first, and then the adapter plate 110 with the guide component 140 is connected to the mounting component 120; wherein, the slide rail 14a of the guide component 140 extends along the direction of gravity; then, the support frame 130 carrying the display substrate 200 is assembled with the guide component 140. Specifically, the sliding component 13a on the support frame 130 is installed on the slide rail 14a of the guide component 140, and the support frame 130 is connected to the adapter plate 110. Under the action of gravity, the support frame 130 drives the display substrate 200 to slide along the slide rail 14a until the sliding component 13a is located at the bottom end of the slide rail 14a. For the right-hand column of display modules, when assembling each display module 1 with the mounting bracket 500, the mounting component 120 can be fixed to the mounting bracket 500 first, and then the adapter plate 110 with the guide component 140 can be connected to the mounting component 120. The slide rail 14a of the guide component 140 is inclined to the right (e.g., Figure 10 As shown in the diagram, the extension direction of the slide 14a is in a " / " shape. Then, the support frame 130 carrying the display substrate 200 is assembled with the guide member 140. Specifically, the sliding member 13a on the support frame 130 is installed on the top of the slide 14a, and the support frame 130 is connected to the adapter plate 110. At this time, there is a certain gap between the display modules in the right column and the display modules in the middle column. Then, the display modules are released, allowing the support frame 130 carrying the display substrate 200 to slide along the slide 14a under gravity (as shown in the diagram). Figure 10As shown in Figure (b), where the arrows indicate the sliding direction, the slider 13a slides along the slide rail 14a until it reaches the bottom, thus pressing the edges of the right-side display modules against the adjacent display modules. The assembly process for the left-side display modules is similar to that for the right-side modules, except that the guide 140 is rotated to the left during assembly, causing the slide rail 14a to tilt to the left, i.e., the extension direction of the slide rail 14a is in a "\" shape. Then, the slider 13a is installed at the top of the slide rail 14a, creating a certain gap between the left-side display modules and the middle-side display modules. After releasing the display modules, they slide along the slide rail 14a under gravity, thus pressing against the adjacent display modules. Figure 11 The arrows in the diagram indicate the direction of extension of the slide 14a on the guide 140 during the assembly of the corresponding display module.

[0072] As can be seen, by utilizing the mounting structure 100 in this embodiment, when multiple display modules 1 are installed one by one on the mounting bracket 500 to achieve splicing between the multiple display modules 1, the guide members 140 in adjacent rows of display modules 1 can be in different guiding states. This ensures that when the sliding member 13a on the support frame 130 is at the top of the slide rail 14a, there is a large gap between the display module 1 to be installed and the adjacent display module 1, thereby preventing collisions between adjacent display modules 1. Afterwards, the display module 1 to be installed is released, and under the action of gravity, it slides along the slide rail 14a, thus pressing against the adjacent display module 1. This mounting structure 100 facilitates the splicing of multiple display modules 1 and prevents collisions between them.

[0073] In some examples, the adapter plate 110 can be magnetically connected to the support frame 130; in other examples, the cooperation between the slider 13a and the slide rail 14a allows the support frame 130 and the adapter plate 110 to move relative to each other in the extension direction of the slide rail 14a, while maintaining connection in the direction perpendicular to the support surface. This disclosure describes an embodiment where the adapter plate 110 and the support frame 130 are magnetically connected as an example.

[0074] Specifically, in some embodiments, such as Figure 2A and Figure 2BAs shown, the support frame 130 includes a support plate 131 and a protective shell 132. The support plate 131 has a support surface and a back surface disposed opposite to each other, and a clearance hole 131v is formed on the support plate 131. The protective shell 132 is disposed opposite to the support plate 131 and defines a receiving space for accommodating the drive circuit board 400. For example, the protective shell 132 can be detachably connected to the support plate 131 by fasteners such as screws. The drive circuit board 400 is used for electrical connection to the display substrate 200 through a flexible circuit board 300, which passes through the clearance hole 131v. A portion of the back surface of the support plate 131 is covered by the protective shell 132, and the mounting surface of the support frame 130 includes the portion of the back surface not covered by the protective shell 132, as well as the surface of the protective shell 132 away from the support plate 131. A slider 13a is fixed to the surface of the protective shell 132 away from the support plate 131.

[0075] In this embodiment, the display substrate 200 is supported by the support frame 130 of the mounting structure 100, and the display module 1 is mounted on the mounting bracket 500 by the adapter plate 110 and the mounting component 120. There is no need to set up a cabinet, thereby simplifying the overall structure of the display module 1 and improving the integration of the whole machine.

[0076] In some embodiments, such as Figure 3 and Figure 6 As shown, the adapter plate 110 includes: an adapter plate body 111 and a first adsorption member 112 fixedly connected to the adapter plate body 111, such as... Figure 2A As shown, the support frame 130 includes a second adsorption member 133, which is arranged opposite to the first adsorption member 112. One of the first adsorption member 112 and the second adsorption member 133 is made of a magnet, and the other is made of iron. For example, the first adsorption member 112 is a permanent magnet, and the second adsorption member 133 is made of iron.

[0077] In one example, the second adsorption member 133 can be an iron nail fixed to the protective shell 132, with the iron nail threaded to the protective shell 132; or, the second adsorption member 133 can also be bonded to the protective shell 132 by an adhesive material, or the second adsorption member 133 can be snapped into the protective shell 132.

[0078] In one example, such as Figure 6 As shown, the adapter plate body 111 has a first mounting groove V4, and the first adsorption member 112 is embedded in the first mounting groove V4. In another example, the first adsorption member 112 can also be bonded to the adapter plate body 111 using an adhesive material.

[0079] In one example, combined Figure 2A , Figure 4 and Figure 6As shown, there are multiple first adsorption elements 112 and multiple second adsorption elements 133, thereby improving the adsorption stability between the adapter plate 110 and the support frame 130.

[0080] In some embodiments, combined with Figure 6 , Figure 13 As shown, a first limiting portion 143 is provided on the side of the guide member 140 facing the adapter plate 110, and a plurality of second limiting portions 144 are provided on the side of the adapter plate 110 facing the guide member 140. The distance between the geometric center of any second limiting portion 144 and a preset axis is the same, which is a first preset value, for example, less than half the length of the guide member 140. The first limiting portion 143 is configured to engage and be fixed with any one of the plurality of second limiting portions 144. When the guide member 140 is in different guiding states (i.e., when the slide 14a extends along different preset directions), the first limiting portion 143 engages with different second limiting portions 144. In one example, one of the first limiting portion 143 and the second limiting portion 144 is a groove structure, and the other is a protrusion. In this embodiment, the first limiting part 143 is a groove structure and the second limiting part 144 is a protrusion as an example for explanation; of course, in other embodiments, the first limiting part 143 may be a protrusion and the second limiting part 144 may be a groove structure. The groove structure may be a through groove or a blind groove. Furthermore, each guide member 140 may have one or more first limiting parts 143, for example, one first limiting part 143 at each end of the guide member 140.

[0081] By setting the first limiting part 143 and the second limiting part 144, it is ensured that the guide member 140 can remain stable after switching to the required guiding state.

[0082] Figure 12 This is a schematic diagram of the adapter plate 110, guide member 140, limiting member 117, first elastic member 1173 and second elastic member 119 provided in some embodiments of this disclosure. Figure 13 A perspective view and a sectional view of the assembled guide member 140, limiting member 117, first elastic member 1173, and second elastic member 119, as shown below. Figure 12 and Figure 13As shown, the mounting structure 100 may further include a limiting member 117 and a first elastic member 1173. The limiting member 117 includes a connecting post 1171 and a third limiting part 1172. A through hole V11 is provided on the adapter plate body 111, penetrating the adapter plate body 111 along its thickness direction. The connecting post 1171 passes through the through hole V11, and its two ends are respectively connected to the guide member 140 and the third limiting part 1172. The first elastic member 1173 can be an elastic member in a compressed state, and its two ends are respectively connected to the adapter plate 110 and the limiting member 117. The aforementioned preset axis is the central axis of the connecting post 1171. The through hole V11 can be located at the center of the first mounting groove V1 or near the center of the first mounting groove V1.

[0083] When it is necessary to switch the guide member 140 to different guiding states, a force away from the adapter plate 110 is applied to the guide member 140, thereby disengaging the first limiting part 143 from the second limiting part 144. After that, the guide member 140 is rotated to switch to the desired guiding state, and then the guide member 140 is released. Under the elastic action of the first elastic member 1173, a force away from the adapter plate 110 is applied to the third limiting part 1172, that is, a force close to the adapter plate 110 is applied to the guide member 140, thereby engaging and fixing the first limiting part 143 and the second limiting part 144, so that the guide member 140 remains stable.

[0084] In one example, the limiting member 117 can be a bolt, the connecting post 1171 can be the shank of the bolt, and the third limiting part 1172 can be the head of the bolt. The first elastic member 1173 can be a compression spring, which is wound around the connecting post 1171.

[0085] In some embodiments, the slide rail 14a includes a first end near the connecting post 1171 and a second end away from the connecting post 1171. When the slider 13a is located at the first end of the slide rail 14a, the central axis of the connecting post 1171 passes through the slider 13a. In this case, after multiple display modules are assembled and spliced, the slider 13a of each display module is located at the position of the rotation axis of the guide 140, which helps to improve the consistency of the splicing seam.

[0086] In some embodiments, see Figure 12 and Figure 13As shown, the guide member 140 includes a first body portion 141 and a second body portion 142 arranged and connected integrally along its extension direction. The slide 14a is a groove formed on the first body portion 141. The first end of the slide 14a is adjacent to the second body portion 142, that is, the first end of the slide 14a is the end closer to the second body portion 142, which is the so-called "bottom end" in the above splicing process; the second end of the slide 14a is the end away from the second body portion 142, which is the so-called "top end" in the above splicing process. The mounting structure 100 also includes a second elastic member 119, which is used to extend and retract along the extension direction of the slide 14a. The fixed end of the second elastic member 119 is fixedly connected to the guide member 140, and in its natural state, a portion of the second elastic member 119 is located inside the first body portion 141, and the free end of the second elastic member 119 is exposed in the slide 14a.

[0087] In this embodiment of the disclosure, the second elastic member 119 extends partially into the slide rail 14a in its natural state. In this case, during the installation and splicing process of the display module 1, when the sliding member 13a slides from the second end to the first end of the slide rail 14a under the gravity of the display module 1, the second elastic member 119 can play a buffering role to prevent collisions between adjacent display modules 1.

[0088] For example, such as Figure 12 and Figure 13 As shown, the guide member 140 has a receiving cavity 14b inside, which communicates with the slide rail 14a. The second elastic member 119 may include a connected spring 1191 and a support portion 1192. One end of the spring 1191 is fixed to the end of the receiving cavity 14b away from the slide rail 14a, and the other end of the spring 1191 is connected to the support portion 1192. When the second elastic member 119 is in its natural state, a portion of the support portion 1192 extends from the receiving cavity 14b into the slide rail 14a. In this embodiment, by placing a portion of the second elastic member 119 in the receiving cavity 14b inside the guide member 140, the stability of the second elastic member 119 during extension and retraction can be improved, preventing the second elastic member 119 from shaking.

[0089] In some embodiments, such as Figure 3 and Figure 6 As shown, the adapter plate 110 has a first receiving groove V1. At least a portion of the guide member 140 is located in the first receiving groove V1 to prevent the thickness of the adapter plate 110 from being too large and affecting the adsorption force between the adapter plate 110 and the support frame 130.

[0090] For example, the first receiving groove V1 is circular, and the limiting member 117 is located at the center of the first receiving groove V1; when the depth of the first receiving groove V1 is less than the thickness of the guide member 140, a portion of the guide member 140 is located in the first receiving groove V1; when the depth of the first receiving groove V1 is greater than or equal to the thickness of the guide member 140, the entire guide member 140 is located in the first receiving groove V1. Here, the depth of the first receiving groove V1 and the thickness of the guide member 140 refer to the dimensions of the first receiving groove V1 and the guide member 140 in the direction perpendicular to the bearing surface, respectively.

[0091] In some embodiments, such as Figure 3 and Figure 6 As shown, the mounting structure 100 includes multiple guide members 140, and the orthographic projections of the multiple guide members 140 on the adapter plate 110 are respectively located on opposite sides of the orthographic projection of the mounting member 120 on the adapter plate 110. The support frame 130 is provided with sliding members 13a corresponding to each guide member 140. By providing multiple guide members 140 and corresponding sliding members 13a, the display module 1 can remain stable during assembly and splicing.

[0092] For example, the mounting structure 100 includes two guide members 140, and the mounting plate 111 has a first receiving groove V1 corresponding to each guide member 140. A plurality of first magnetic members 151 may be disposed between the two guide members 140.

[0093] In some embodiments, such as Figure 3 As shown, the adapter plate 110 has multiple support blocks 113 on the side opposite to the mounting component 120. These support blocks 113 support the carrier frame 130, and each support block 113 has a support surface opposite to the mounting component 120. The support surfaces of the multiple support blocks 113 are located on the same plane. In this case, it is only necessary to ensure that the support surfaces of the multiple support blocks 113 are on the same plane, thus reducing the flatness requirements on the surface of the mounting plate 111 and lowering the precision requirements of the manufacturing process.

[0094] For example, multiple support blocks 113 are disposed near the edge of the mounting plate 111. For instance, the mounting plate 111 includes a first edge E1 and a second edge E2 arranged along the height direction, and multiple support blocks 113 are disposed near both the first edge E1 and the second edge E2.

[0095] In some embodiments, combined with Figure 3 and Figure 6As shown, the mounting structure 100 also includes multiple threaded rods 114. The adapter plate 110 has threaded holes V3 that match the threaded rods 114. Specifically, the threaded holes V3 penetrate the mounting plate 111 along its thickness direction, and the threaded rods 114 pass through the threaded holes V3, with the length of the threaded rods 114 greater than the depth of the threaded holes V3. When multiple display modules 1 are spliced ​​together and there is a step difference in the display surfaces of different display modules 1, the threaded rods 114 are rotated to support the support frame 130, thereby making the display surfaces of the different display modules 1 flush.

[0096] For example, the mounting structure 100 includes at least four threaded rods 114, with at least two threaded rods 114 provided at positions near the first edge E1 and the second edge E2 of the mounting plate 111, thereby improving the support stability of the support frame 130.

[0097] Figure 14 This is an exploded view of the mounting component 120 and the drive mechanism provided in some embodiments of this disclosure, such as... Figure 8 and Figure 14 As shown, the mounting component 120 includes a first mounting portion 121, a second mounting portion 122, and a third mounting portion 123. The first mounting portion 121 is connected to the adapter plate 110. The second mounting portion 122 and the third mounting portion 123 are located on the side of the first mounting portion 121 away from the adapter plate 110 and are disposed opposite to each other. The second mounting portion 122 and the third mounting portion 123 can be connected to the first mounting portion 121 as an integral structure. The second mounting portion 122 and the third mounting portion 123 can be connected to the mounting bracket using fasteners such as screws, for example... Figure 14 As shown, both the second mounting portion 122 and the third mounting portion 123 are provided with screw holes 124v. When the mounting component 120 is connected to the mounting bracket 500, the second mounting portion 122 and the third mounting portion 123 are positioned on opposite sides of the mounting bracket 500, and screws 124 are screwed into the screw holes 124v on the second mounting portion 122 and the third mounting portion 123 to clamp the mounting bracket 500. Of course, other methods can also be used to connect the mounting component 120 to the mounting bracket 500.

[0098] In some embodiments, the adapter plate 110 is magnetically connected to the mounting member 120. For example, in combination with... Figures 4 to 6As shown, the adapter plate 110 further includes a third adsorption member 115, which is disposed on the side of the mounting plate 111 facing the mounting member 120. The mounting member 120 further includes a fourth adsorption member 116 corresponding to the third adsorption member 115, which is disposed on the side of the first mounting portion 121 facing the adapter plate 110. The third adsorption member 115 and the fourth adsorption member 116 are magnetically attracted. For example, one of the third adsorption member 115 and the fourth adsorption member 116 is made of a magnet, and the other is made of iron. Exemplarily, a second mounting groove is formed on the mounting plate 111 of the adapter plate 110, and the third adsorption member 115 is embedded in the second mounting groove; or, the third adsorption member 115 is bonded to the mounting plate 111 by an adhesive material. A third mounting groove is formed on the first mounting portion 121, and the fourth adsorption member 116 is embedded in the third mounting groove; or, the fourth adsorption member 116 is bonded to the first mounting portion 121 by an adhesive material. The number of third adsorption components 115 and fourth adsorption components 116 are both multiple, in order to improve the magnetic attraction stability between the adapter plate 110 and the mounting component 120.

[0099] In some embodiments, the mounting structure 100 further includes a driving mechanism for driving the adapter plate 110 to move relative to the mounting member 120 in a direction parallel to the bearing surface. By driving the adapter plate 110 through the driving mechanism, the position of the support frame 130 can be adjusted in a plane parallel to the bearing surface. When the mounting structure 100 is used in a display module, the driving action of the driving mechanism causes the support frame 130 and the display substrate it supports to move, thereby further improving the consistency of the splicing seam.

[0100] In some embodiments, combined with Figure 5 , Figure 14 and Figure 15As shown, a force-bearing column 118 is provided on the side of the adapter plate 110 facing the mounting member 120, and the force-bearing column 118 is fixedly connected to the adapter plate 110. A second receiving groove V2 is provided on the mounting member 120, and the second receiving groove V2 has an opening facing the adapter plate 110. The second receiving groove V2 is formed on the first mounting part 121. The second receiving groove V2 can be a through groove that penetrates the first mounting part 121 in a direction perpendicular to the bearing surface, or it can be a blind groove. At least a portion of the force-bearing column 118 extends into the second receiving groove V2 through the opening. The projected area of ​​the force-bearing column 118 on the adapter plate 110 is smaller than the projected area of ​​the opening of the second receiving groove V2 on the adapter plate 110. Furthermore, the force-bearing column 118 can move relative to the opening in a direction parallel to the bearing surface. The size of the force-bearing column 118 and the opening of the second receiving groove V2 satisfies the following condition: when the central axis of the force-bearing column 118 coincides with the central axis of the opening, the edge of the projected area of ​​the force-bearing column 118 on the adapter plate 110 does not contact the edge of the projected area of ​​the opening on the adapter plate 110. A driving mechanism applies force to the force-bearing column 118 in a first direction and a second direction to drive the adapter plate 110 to move relative to the mounting member 120 along the first and second directions. The first and second directions intersect and are both parallel to the bearing surface. For example, the first direction is perpendicular to the second direction.

[0101] In some embodiments, the first mounting portion 121 of the mounting member 120 includes a first end face facing the adapter plate 110 and a side face connected to the first end face. A plurality of mounting holes 121v are provided around the second receiving groove V2, communicating with the second receiving groove V2 and extending in a direction away from the central axis of the second receiving groove V2. The mounting holes 121v can be through holes, that is, the mounting holes 121v extend from the second receiving groove V2 to the side face of the mounting member 120. The extending direction of the mounting holes 121v is the axial direction of the mounting holes 121v. The mounting holes 121v provided on opposite sides of the second receiving groove V2 along the first direction extend along the first direction, and the mounting holes 121v provided on opposite sides of the second receiving groove V2 along the second direction extend along the second direction.

[0102] In some embodiments, the force-bearing column 118 is driven to move in a first direction and a second direction by magnetic force, specifically, as shown in the example below. Figure 14 and Figure 15 As shown, the driving mechanism includes multiple magnetic components, which are respectively disposed on opposite sides of the force-bearing column 118 along a first direction and on opposite sides along a second direction. Each magnetic component includes a first magnetic element 151 and a second magnetic element 152 that are oppositely disposed and magnetically repulsive. The first magnetic element 151 is fixedly connected to the force-bearing column 118, and the second magnetic element 152 is connected to the mounting component 120. For example, the second magnetic element 152 can be disposed in a mounting hole 121v. The mounting hole 121v can be a through hole.

[0103] The magnetic force between the first magnetic element 151 and the second magnetic element 152 is adjustable, and / or the second magnetic element 152 is axially movable along the mounting hole 121v.

[0104] In one example, the second magnetic element 152 is an electromagnet, and the magnetic force between the first magnetic element 151 and the second magnetic element 152 is changed by adjusting the current flowing through the electromagnet.

[0105] For example, the dimensions of the force-bearing column 118 in both the first direction and the second direction are between 12 and 20 mm to facilitate the installation of the first magnetic element 115. When the central axis of the force-bearing column 118 coincides with the central axis of the opening, there is an annular gap between the orthographic projection edge of the force-bearing column 118 on the adapter plate 110 and the orthographic projection edge of the opening on the adapter plate 110. The width of this annular gap is between 5 and 8 mm to ensure that sufficient magnetic force can be generated between the first magnetic element 151 and the second magnetic element 152.

[0106] For example, the orthographic projection of the force-bearing column 118 and the orthographic projection of the opening are truly similar in shape to each other. For example, the orthographic projection of the force-bearing column 118 and the orthographic projection of the opening are both polygons (e.g., rectangles, octagons, decagons, etc., even-numbered polygons). They can also be other shapes, as long as the shape has two oppositely arranged sides parallel to the direction to be adjusted (the first direction and the second direction), such as a cross shape.

[0107] In another example, such as Figure 14 and Figure 15 As shown, a lead screw 153 and a nut 154 are provided in the mounting hole 121v. The nut 154 is fixedly connected to the inner wall of the mounting hole 121v, and the lead screw 153 is threadedly connected to the nut 154 and fixedly connected to the second magnetic component 152. The lead screws 153 and the corresponding mounting holes 121v provided on opposite sides of the force-bearing column 118 along the first direction extend along the first direction, and the lead screws 153 and the corresponding mounting holes 121v provided on opposite sides of the force-bearing column 118 along the second direction extend along the second direction. When it is necessary to control the force-bearing column 118 to move relative to the mounting member 120 in the first direction, the lead screws 153 on opposite sides of the force-bearing column 118 along the first direction are rotated to move the lead screws 153 along the first direction, thereby driving the second magnetic member 152 to move along the first direction, and thus causing the force-bearing column 118 to move relative to the mounting member 120 in the first direction; when it is necessary to control the force-bearing column 118 to move relative to the mounting member 120 in the second direction, the lead screws 153 on opposite sides of the force-bearing column 118 along the second direction are rotated to move the lead screws 153 along the second direction, thereby driving the second magnetic member 152 to move along the second direction, and thus causing the force-bearing column 118 to move relative to the mounting member 120 in the second direction.

[0108] When the second magnetic element 152 can move axially along the mounting hole 121v, the second magnetic element 152 can be a permanent magnet or an electromagnet.

[0109] In other embodiments, a motor drives the force-bearing column 118 to move in a first direction and a second direction. For example... Figure 16 As shown, the drive mechanism includes multiple drive motors 155, which are respectively disposed on at least one side of the force-bearing column 118 along a first direction and at least one side along a second direction, and are connected to the mounting member 120. For example, multiple mounting holes 121v are installed on opposite sides of the second receiving groove V2 along the first direction and on opposite sides along the second direction. The mounting holes 121v communicate with the second receiving groove V2 and extend in a direction away from the second receiving groove V2. The body 1551 of the drive motor 155 is disposed in the mounting hole 121v, and the drive shaft 1552 of the drive motor 155 is connected to the force-bearing column 118. The body 1551 is used to drive the drive shaft 1552 to extend and retract along its axial direction, so as to drive the force-bearing column 118 to move along the axial direction of the drive shaft 1552.

[0110] For example, drive motors 115 are provided on both sides of the force-bearing column 118 along the first direction and on both sides of the force-bearing column 118 along the second direction. The axial direction of the drive shaft 1552 is the extension direction of the drive shaft 1552, that is, the arrangement direction of the body 1551 of the drive motor 155 and the force-bearing column 118.

[0111] For example, the force-bearing column 118 has a groove on its side facing the drive motor 155, and the end of the drive shaft 1552 extends into the groove. For example, the first direction is... Figure 16 The left and right directions, the second direction is Figure 16 In the vertical direction, the upper and lower drive motors 155 are used to drive the force-bearing column 118 to move in the vertical direction, and the left and right drive motors 155 are used to drive the force-bearing column 118 to move in the left and right direction; and the grooves facing the upper and lower drive motors 155 extend in the left and right direction, so as to ensure that when the force-bearing column 118 moves in the vertical direction, it will not be obstructed by the drive shafts 1552 on both sides; and when it moves in the left and right direction, it will not be obstructed by the drive shafts 1552 on both sides.

[0112] In some other embodiments, a linkage structure is used to drive the force-bearing column 118 to move along a first direction and a second direction. For example... Figure 17As shown, the drive mechanism includes: a driver (not shown) and a first transmission rod 156 and a second transmission rod 157 connected to the driver. The first transmission rod 156 extends along a first direction, and the second transmission rod 157 extends along a second direction and is slidably disposed on the first transmission rod 156. A force-bearing column 118 is connected to the second transmission rod 157. The driver is used to drive the second transmission rod 157 to move relative to the first transmission rod 156 along the first direction, and to drive the first transmission rod 156 to move relative to the mounting member 120 along the second direction.

[0113] The driver can be directly connected to the first transmission rod 156 and the second transmission rod 157 to drive the movement of the first transmission rod 156 and the second transmission rod 157, or it can be driven by transmission components such as a conveyor belt or a conveyor chain.

[0114] In some other embodiments, the force-bearing column 118 is moved by compressing it with a variable-volume airbag. Specifically, for example... Figure 18 As shown, the drive mechanism may further include multiple variable-volume airbags 158, which are located in the second receiving groove V2 and respectively disposed on opposite sides of the force-bearing column 118 along the first direction and the second direction. By inflating and deflating the airbags 158, their volume can be adjusted, thereby driving the force-bearing column 118 to move in the first and second directions. In this case, it is not necessary to open the aforementioned mounting holes on the mounting member 120.

[0115] Figure 19 This is a schematic diagram of the leveling components provided in some embodiments of this disclosure. Figure 20 This is a schematic diagram illustrating the use of the leveling assembly 160 to flatten a warped display module 1. Figure 21 This is a schematic diagram of the spliced ​​display module 1 with leveling components, as shown below. Figure 19 and Figure 21 As shown, the mounting structure 100 also includes a leveling assembly 160 disposed on the mounting surface of the support frame 130. The leveling assembly 160 includes multiple fasteners 161 and an adjustment mechanism 162. The fasteners 161 are fixed to the mounting surface and located at the edge of the support frame 130. Furthermore, the fasteners 161 can be disposed in areas of the support plate 131 not covered by the protective shell 132. For example, the fasteners 161 can be block structures, and the fasteners 161 can be connected to the support plate 131 as an integral structure. Alternatively, they can be fixedly connected to the support plate 131 in other ways, such as by bonding the fasteners 161 to the support plate 131 with adhesive material, or by fasteners such as screws.

[0116] The adjustment mechanism 162 is fixed on the mounting surface and connected to the fixing member 161. The adjustment mechanism 162 is used to apply a pulling force or a pushing force to the fixing member 161 to adjust the distance between the fixing member 161 and the adjustment mechanism 162.

[0117] like Figure 20 As shown, when the support frame 130 warps, causing the light-emitting surface of the entire display module 1 to become uneven, the adjustment mechanism 162 applies a pulling force to the fixing member 161 at the warped position, thereby making the support surface of the warped support frame 130 more flat, so as to improve the flatness of the light-emitting surface of the display module 1.

[0118] For example, such as Figure 19 As shown, the support frame 130 is polygonal, and a fixing member 161 is provided at each corner of the polygon; the fixing members 161 at two adjacent corners are connected to the same adjustment mechanism 162, so that the leveling component 160 can be used to flatten the display module 1 when the edge of the display module 1 is warped in any shape.

[0119] The fixing member 161 is connected to the corresponding adjustment mechanism 162 via a connector 163. One end of the connector 163 is connected to the fixing member 161, and the other end is connected to the adjustment mechanism 162. The distance between the two ends of the connector 163 is adjustable.

[0120] For example, the connector 163 can be a pull rope, and the adjusting mechanism 162 has a roller inside. One end of the pull rope is connected to the fixing member 161, and the other end is wound around the roller. By controlling the rotation of the roller, the pull rope is pulled, thereby adjusting the distance between the fixing member 161 and the adjusting mechanism 162.

[0121] For example, the connector 163 is a telescopic rod, the adjusting mechanism 162 is connected to the telescopic rod, and the distance between the fixing member 161 and the adjusting mechanism 162 is adjusted by controlling the extension and retraction of the telescopic rod.

[0122] For example, the fastener 161 and the adjustment mechanism 162 are fixed in the area of ​​the support plate 131 not covered by the protective shell 132.

[0123] This disclosure also provides a display module, including at least one display substrate 200 and the mounting structure 100 in the above embodiments, wherein the display substrate 200 is disposed on the bearing surface of the support frame 130.

[0124] For example, the display substrate 200 can be bonded to the support surface using an adhesive material. Of course, other fasteners can also be used to fix the display substrate 200 to the support surface of the support frame 130.

[0125] In addition, such as Figure 2BAs shown, the display module may also include a flexible circuit board 300 and a driving circuit board 400. The driving circuit board 400 is located in the accommodating space defined by the protective shell 132 and the carrier plate 131. The flexible circuit board 300 passes through the clearance hole on the carrier plate 131 and is electrically connected to the driving circuit board 400 and the display substrate 200, thereby transmitting the driving signal provided by the driving circuit board 400 to the display substrate 200.

[0126] This disclosure also provides a splicing display device, including multiple display modules as described in the above embodiments.

[0127] Multiple splicing display modules can be arranged in an array, for example, in multiple rows and one column, one row and multiple columns, or multiple rows and multiple columns.

[0128] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
