[0087] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0088] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0089] Unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0090] As used herein, “parallel” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°.

[0091] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on another layer or substrate, or that there is an intermediate layer between the layer or element and another layer or substrate.

[0092] This document describes exemplary embodiments with reference to sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and regions is enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Therefore, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0093] Figure 1 is a schematic diagram of a splicing display device provided in some embodiments. As shown in Figure 1, in some splicing display devices, multiple splicing units 1 are spliced ​​together. Each splicing unit 1 includes a housing and at least one display component supported on the housing. In one example, the display component may include a carrier plate and a display substrate supported thereon. The carrier plate is fixed to a corresponding housing, and the display substrate is fixed to the side of the carrier plate away from the housing. The display substrate may include a substrate and a light-emitting element disposed on the substrate. The substrate may be a glass substrate, and the light-emitting element may include a micro-inorganic light-emitting diode.

[0094] During the assembly of the splicing display device, due to limitations in process conditions and the flatness of the cabinet surface itself, it is inevitable that there will be a step difference between adjacent cabinets. This results in a step difference on the display surface of the entire splicing display device at the splicing position of adjacent splicing units 1, which in turn affects the flatness.

[0095] In this embodiment of the disclosure, "step difference" refers to the height difference in the thickness direction of the display component (hereinafter referred to as the Z direction).

[0096] Figure 2 is an exploded view of the splicing display device provided in some embodiments of this disclosure; Figure 3 is an exploded view of the splicing unit in the splicing display device provided in some embodiments of this disclosure; Figure 4 is a side view of two adjacent splicing units provided in some embodiments of this disclosure; Figure 5 is a top view of four splicing units provided in some embodiments of this disclosure; Figure 6 is a perspective view of four splicing units at the splicing position provided in some embodiments of this disclosure; Figure 7 is a perspective view of four cabinets at the splicing position provided in some embodiments of this disclosure; and Figure 8 is a partial perspective view of four cabinets not spliced ​​in some embodiments of this disclosure. As shown in Figures 2 to 8, the splicing display device in the embodiments of this disclosure includes multiple splicing units 1 spliced ​​together, wherein each splicing unit 1 includes a display component 10 and a cabinet 20.

[0097] For example, the display assembly 10 may include a display substrate 11 and a driving circuit board (not shown) for providing signals to the display substrate 11. The display substrate 11 may include a substrate and a light-emitting element located on the substrate. The light-emitting element may include a miniature inorganic light-emitting diode, such as a Mini-LED or Micro-LED. The driving circuit board is located on the non-display side of the display substrate 11 and is electrically connected to the display substrate 11 via a flexible circuit board 13. In an optional example, the display assembly 10 may further include a carrier 12 for supporting the display substrate 11, with the driving circuit board located on the side of the carrier 12 away from the display substrate 11. In one example, the carrier 12 is a plate-like structure, and the carrier 12 may be provided with clearance holes, through which the flexible circuit board 13 passes. A protective shell 14 and the carrier 12 form a protective space, in which the driving circuit board is located. In another example, the carrier 12 may be a frame structure.

[0098] For example, the cabinet 20 is disposed on the non-display side of the display component 10; a support area 30a is provided at the edge of the cabinet 20, the support area 30a has a support surface 30 facing away from the cabinet 20, and the support surface 30 is configured to support at least the display component 10 in the splicing unit 1 to which the support area 30a belongs.

[0099] It is understood that a display assembly may include multiple display panels and a drive circuit board for providing signals to the multiple display panels, and a housing is used to support the multiple display panels in the display assembly. As shown in Figure 2, the display assembly 10 includes two display panels 11, and the housing 20 is used to support the two display panels 11.

[0100] In this arrangement, the support areas 30a in different splicing units 1 are spaced apart, and the support surface 30 of the support area 30a in at least one splicing unit 1 is also configured to support the display components 10 in adjacent splicing units 1.

[0101] In this embodiment of the present disclosure, at least one support area 30a in the splicing unit 1 can simultaneously support the display components 10 in the adjacent splicing unit 1. In this case, even if there is a step difference between two adjacent cabinets 20 during splicing, it can prevent the two adjacent display components 10 from having an obvious step difference at the splicing position.

[0102] For example, in each pair of adjacent splicing units 1, the support surface 30 of at least one support area 30a of one splicing unit 1 is configured to support the display components 10 in the two adjacent splicing units 1, thereby helping to reduce the step difference between the display components 10 of each pair of adjacent splicing units 1.

[0103] Among them, multiple splicing units 1 can be arranged in an array. In this embodiment of the present disclosure, "two adjacent units" can be two adjacent units in the same row or two adjacent units in the same column.

[0104] For example, in any two adjacent splicing units 1, the edges of the two display components 10 that are close to each other are supported on the same support area 30a, which helps to reduce the step difference between the display components 10 of each two adjacent splicing units 1.

[0105] For example, multiple splicing units 1 are arranged in multiple rows and columns, and each display component 10 is a rectangular structure, as shown in Figure 6. In four splicing units 1 located in two adjacent rows and two adjacent columns, the corners of each display component 10 that are close to each other are supported on the support surface 30 of the same support area 30a, so as to prevent step difference from occurring at the splicing position of the four adjacent display components 10 and improve the flatness of the splicing display device.

[0106] For example, referring to Figures 5 to 8, the four splicing units 1 located in two adjacent rows and two adjacent columns are respectively denoted as: upper left splicing unit, upper right splicing unit, lower left splicing unit, and lower right splicing unit. The lower right corner of the housing 20 of the upper left splicing unit is provided with a support area 30a, and the support surface 30 of the support area 30a can simultaneously support the corners of the display components 10 of the four splicing units 1.

[0107] For example, the cabinet 20 has a cutout 20v. During the application of the splicing display device, signal transmission lines can pass through the cutout 20v to provide the drive signals provided by the system motherboard to the drive circuit board. The cabinet 20 has a frame-shaped structure, and the outline of the cabinet 20 projected onto the reference plane (here, "outline" refers to the outer outline) is a polygon. The reference plane is a plane perpendicular to the Z direction. The support area 30a is located in the interior corner region of the polygon, that is, the region located inside the polygon and adjacent to the corner. For example, each cabinet 20 is provided with a support area 30a. Each support area 30a supports the display component 10 in its own splicing unit 1, and also supports the display components 10 in adjacent splicing units 1, so that the positions of every two adjacent display components 10 overlap on the same support area 30a, improving the flatness of the splicing display device.

[0108] For example, each box 20 has the same structure to facilitate standardized production. For example, as shown in Figure 5, each box 20 has a support area 30a at its right edge and lower edge, and the support area 30a at the right edge and the support area 30a at the lower edge can be connected to form an L-shaped integrated structure.

[0109] For example, there is a gap between the display components 10 of two adjacent splicing units 1; as shown in FIG7, at least one support area 30 has a groove 30v, the groove 30v overlaps with the orthographic projection of the aforementioned gap on the reference plane, and a light-absorbing material (not shown) is disposed in the groove 30v. By providing a light-absorbing material, light leakage at the splicing gap position can be reduced, and the dark state consistency of the splicing display device can be improved.

[0110] For example, in Figures 5 to 8, an L-shaped support area 30a is provided at the lower right corner of the housing 20 of the upper left splicing unit. This support area 30a can simultaneously support the corners of the display components 10 of the four splicing units 1. In addition, an L-shaped groove 30v is formed on the L-shaped support area 30a. The intervals between the display components 10 of the upper left splicing unit and the display components 10 of the upper right splicing unit, and the intervals between the display components 10 of the upper left splicing unit and the display components 10 of the lower left splicing unit, all overlap with the orthographic projection of the L-shaped groove 30v on the reference plane.

[0111] For example, the recess 30v includes a first recess extending along the row direction. The spacing between two adjacent display components 10 in the same column overlaps with the orthographic projection of the first recess on the reference plane. The width of the first recess is greater than the spacing width between two adjacent display components 10 in the same column, and the length of the first recess is less than the spacing length between two adjacent display components 10 in the same column. For example, the recess 30v includes a second recess extending along the column direction. The spacing between two adjacent display components 10 in the same row overlaps with the orthographic projection of the second recess on the reference plane. The width of the second recess is greater than the spacing width between two adjacent display components 10 in the same row, and the length of the second recess is less than the spacing length between two adjacent display components 10 in the same row.

[0112] For example, the distance between any two adjacent support areas 30a of splicing units 1 (D1 and D2 as indicated in Figure 5) is greater than or equal to 60mm. In this case, when the display component 10 is simultaneously attached to the support areas 30a of multiple splicing units 1, even if there is a step difference between the support surfaces 30 of the support areas 30a in different splicing units 1, it can be ensured that different positions of the display component 10 form a smooth transition without any abrupt height changes.

[0113] For example, as shown in Figures 7 to 9, one of every two adjacent cabinets 20 is designated as the first cabinet and the other as the second cabinet. Both the first and second cabinets include a main structure 21. The first cabinet also includes a first eaves structure 22 disposed on the main structure 21. The first eaves structure 22 is configured to cover part of the edge area of ​​the main structure 21 of the second cabinet, and the support surface 30 is located on the surface of the first eaves structure 22 facing the display component 10. During the assembly of the splicing display device, multiple cabinets 20 can be assembled first, such that the first eaves structure 22 of one of every two adjacent cabinets 20 overlaps the main structure 21 of the other cabinet 20, thereby facilitating the overlap of adjacent positions of two adjacent display components 10 on the same support area 30a.

[0114] For example, the surface of the first eaves structure 22 facing the display component 10 is a concave-convex surface, which includes a connected convex surface and a concave surface. The convex surface is located on the side of the concave surface extending towards the display component 10, and the area where the convex surface is located serves as the support area 30a. The convex surface is the aforementioned support surface 30. In one example, there is a height difference (h as shown in FIG. 4) between the convex surface and the concave surface extending, and this height difference h is in the range of 1 to 1.5 mm. When a part of the display component 10 overlaps the support surface 30 (i.e., the convex surface) and another part overlaps the concave surface, a smooth transition can be created between different positions of the display component 10, improving the flatness of the splicing display device.

[0115] For example, multiple splicing units 1 are arranged in multiple rows along the height direction of the splicing display device, with each row including multiple splicing units 1. Each cabinet 20 has a first eaves structure 22 on its right and lower edges. Figure 9 shows a perspective view of the lower right corner of the cabinet 20. Among the multiple splicing units 1, except for the bottommost row and the rightmost column, in each of the remaining splicing units 1, the first eaves structure 22 on the right edge of the cabinet 20 overlaps with the main structure 21 of the right cabinet 20; the first eaves structure 22 on the lower edge overlaps with the main structure 21 of the lower cabinet 20.

[0116] Figure 10 is a schematic diagram of the upper left corner position of the splicing unit 1 provided in some embodiments of this disclosure. As shown in Figure 10, the edge of each display component 10 extends beyond the edge of the cabinet 20. That is, a portion of the orthographic projection of the display component 10 on the reference surface extends beyond the orthographic projection of the cabinet 20 on the reference surface. The width of the extended portion is between 1 and 2 mm to prevent the display component 10 from being damaged due to excessive extension.

[0117] For example, as shown in Figure 8, the second housing also includes a limiting post 24 disposed on the main structure 21. As shown in Figures 8 and 9, the first roof structure 22 has a clearance notch 22v, and part of the limiting post 24 is located in the clearance notch 22v. During the assembly of multiple housings 20, for any two adjacent housings 20, the two housings 20 can be aligned first, so that the limiting post 24 of one housing 20 is located in the clearance notch 22v of the first extension platform of the other housing 20, thereby preventing the two housings 20 from moving relative to each other in the X and Y directions. Then, the two adjacent housings 20 are fixedly connected to improve the accuracy of the relative position of the adjacent housings 20. The X direction is perpendicular to the Y direction, and both the X and Y directions are perpendicular to the Z direction.

[0118] For example, any two adjacent housings 20 can be detachably connected by fasteners. For instance, there may be multiple fasteners, which may include a first screw. As shown in Figures 8 and 9, in any two adjacent housings 20, one housing 20 has a first screw hole V1, and the other housing 20 has a second screw hole V2 corresponding to the first screw hole V1. The first screw extends parallel to the X direction, passes through the first screw hole V1, and is screwed into the second screw hole V2, thereby connecting the two adjacent housings 20. For example, adjacent housings 20 arranged along the X direction are connected by a first screw extending along the X direction, and adjacent housings 20 arranged along the Y direction are connected by a first screw extending along the Y direction.

[0119] In addition, multiple fasteners may also include a second screw. As shown in Figure 11, in any two adjacent housings 20, one housing 20 is provided with a first mounting part 71, and the first mounting part 71 has a third screw hole V3. The other housing 20 is provided with a second mounting part 72, and the second mounting part 72 has a fourth screw hole V4. The first mounting part 71 and the second mounting part 72 are arranged in the Z direction. The second screw extends in the Z direction, passes through the fourth screw hole V4 and is screwed into the third screw hole V3, thereby connecting the two adjacent housings 20.

[0120] Figure 12A is a cross-sectional view obtained along the cutting line AA' of Figure 6. Exemplarily, as shown in Figures 3, 6, 7, and 12A, the splicing unit 1 further includes a first magnetic component 50. The first magnetic component 50 includes a first part 51 and a second part 52 that are magnetically attracted to each other. The first part 51 is disposed on the display component 10, for example, on the support plate 12 of the display component 10. The second part 52 is disposed on the housing 20. In one example, one of the first part 51 and the second part 52 is a magnet, and the other is made of a ferromagnetic material, such as iron, so that the first part 51 and the second part 52 can approach each other or even attract each other. In another example, both the first part 51 and the second part 52 are magnets, and the magnetic poles at their two ends that are close to each other are opposite, which also allows the first part 51 and the second part 52 to approach each other or even attract each other.

[0121] As shown in Figure 12A, the splicing unit 1 further includes a mounting base 53, which is disposed on the housing 20 and configured to move relative to the housing 20 along the Z direction; wherein, the second component 52 is fixed on the mounting base 53. In this embodiment of the present disclosure, by controlling the movement of the mounting base 53 relative to the housing 20 in the Z direction, the display component 10 can be adjusted in the Z direction, thereby further improving the flatness of the display surface of the splicing display device.

[0122] For example, as shown in FIG12A, the housing 20 has a threaded hole V0. The mounting base 53 includes a mounting part 531 and a screw part 532. At least a portion of the screw part 532 is located in the threaded hole V0. The mounting part 531 is fixedly connected to one end of the screw part. The second component 52 is fixed on the mounting part 531. By rotating the mounting base 53, the mounting base 53 can be moved relative to the housing 20 in the Z direction.

[0123] For example, as shown in Figures 6, 8, and 12A, the housing 20 may include a positioning structure 54 integrally formed with the main structure 21. The positioning structure 54 has a positioning groove 54v, and a threaded hole V0 may be formed at the bottom of the positioning groove 54v. The mounting part 531 of the mounting base 53 and the second component 52 are located in the positioning groove 54v. For example, a positioning structure 542 is provided at two diagonal positions (such as the upper left corner and the lower right corner) of each housing 20; at the other two diagonal positions (such as the upper right corner and the lower left corner) of each housing 20, the mounting base 53 is directly threaded to the main structure 21 of the housing 20, that is, no positioning structure 54 is provided on the outer periphery of the mounting base 53.

[0124] For example, when the central axis of the positioning groove 54v is collinear with the central axis of the corresponding first component 51, there is a certain gap between the two ends of the first component 51 in the X direction and the inner side of the positioning groove 54v (d1 and d2 as shown in Figures 6 and 12A, where (d1+d2) ranges from 3mm to 5mm). Furthermore, the surface of the positioning structure 54 facing the display component 10 is higher than the surface of the second component 52 facing the display component 10 and the surface of the mounting portion 531 facing the display component 10 in the positioning groove 54v. In this case, during the splicing of two adjacent splicing units in the X direction, the presence of the positioning structure 54 and the positioning groove 54v prevents them from being squeezed or bumped, providing space redundancy during splicing. Correspondingly, when supporting two adjacent display components in the X direction on the housing, the presence of the positioning structure 54 and the positioning groove 54v prevents them from being squeezed or bumped, providing space redundancy during placement.

[0125] For the positioning structure 54 shown in Figures 6 and 12A, when the central axis of the positioning groove 54v is collinear with the central axis of the corresponding first component 51, there can also be a certain gap between the two ends of the first component 51 in the Y direction and the inner side of the positioning groove 54v, so as to prevent the two adjacent display components from colliding in the Y direction during the splicing process.

[0126] It should be noted that in Figures 6 and 12A, the positioning structure 54 is illustrated as a cylindrical structure. Of course, the positioning structure 54 can also be set to other shapes, as long as it can limit the positioning of the first component 51 in the X direction. For example, as shown in Figure 12B, the positioning structure 54 is a V-shaped retaining wall, surrounding the mounting base 53 and the second component 52. The threaded hole V0 is opened on the main structure 21 of the housing 20, eliminating the need for the aforementioned positioning groove 54v. Furthermore, the distance between the positioning structure 54 and the corresponding first component 51 in the X direction can be within the range of 3mm to 5mm.

[0127] It should also be noted that the magnetic attraction between the first component 51 and the second component 52 in this embodiment means that there is a mutual magnetic force between the first component 51 and the second component 52, and it is not necessarily required that the first component 51 and the second component 52 be in contact. For example, in practical applications, as shown in FIG12A, there may be a gap between the first component 51 and the second component 52, and the gap may be between 0.2mm and 0.45mm.

[0128] Figure 13 is a schematic diagram of the second component 52 disposed on the mounting base 53 according to some embodiments of this disclosure. Exemplarily, the mounting portion 531 is provided with a mounting groove, and the second component 52 is fixed in the mounting groove, for example, the second component 52 is engaged in the mounting groove. Exemplarily, as shown in Figure 13, the mounting base 53 also has at least two oppositely disposed notches 53v, which communicate with the mounting groove to facilitate the removal of the second component 52 from the mounting groove using a clamping member, thereby facilitating product maintenance.

[0129] Figure 14 is a plan view of multiple boxes 20 provided in some other embodiments of this disclosure. Figure 15 is a schematic diagram of two adjacent boxes 20 in a close proximity position provided in some other embodiments of this disclosure. Figure 16 is a schematic diagram of two adjacent boxes 20 spliced ​​together in some other embodiments of this disclosure. In the embodiments shown in Figures 11 to 13, the splicing display device is similar to the arrangement in the aforementioned embodiments, except that in the embodiments shown in Figures 14 to 16, multiple support areas 30a are provided at least one edge position of each box 20. For example, multiple support areas 30a are provided at the edges of adjacent two sides of each box 20. A straight groove 30v is provided on each support area 30a.

[0130] Figure 17 is a plan view of a plurality of boxes 20 provided in some embodiments of the present disclosure, Figure 18 is a perspective view of a single box 20 in Figure 17, Figure 19 is a partial schematic diagram of four adjacent boxes 20 provided in some embodiments of the present disclosure, and Figure 20 is a schematic diagram of four adjacent boxes 20 spliced ​​together in some embodiments of the present disclosure. The dashed lines L1 and L2 in Figure 20 represent the spacing positions of the four adjacent display components 10. The embodiments shown in Figures 17 to 20 are similar to those shown in Figures 4 to 13. In any two adjacent splicing units 1, the edges of the two display components 10 that are close to each other are supported on the same support area 30a; and in the four splicing units 1 located in two adjacent rows and two adjacent columns, the corners of each display component 10 that are close to each other are supported on the support surface 30 of the same support area 30a; any two adjacent boxes 20 are respectively a first box and a second box, both of which include a main structure 21, and the first box also includes a first eaves structure 22. The first eaves structure 22 is located on the side of the main structure 21 of the second housing facing the display component 10, and a support area 30a is provided on the side of the first eaves structure 22 facing the display component 10.

[0131] The embodiments shown in Figures 17 to 20 differ from those in Figures 4 to 13 only in that, in addition to the main structure 21 and the first eaves structure 22, the first housing also includes a second eaves structure 23. The first eaves structure 22 and the second eaves structure 23 are arranged opposite each other in the Z-direction, with the second eaves structure 23 located on the side of the first eaves structure 22 away from the display component 10. In the Z-direction, the main structure 21 is located between the first eaves structure 22 and the second eaves structure 23. The second eaves structure 23, the first eaves structure 22, and the main structure 21 of the first housing define a limiting groove V5, with a portion of the main structure 21 of the second housing located within the limiting groove V5. The arrangement of the first eaves structure 22 and the second eaves structure 23 allows for limiting the movement of two adjacent housings 20 in the Z-direction.

[0132] For example, a first eaves structure 22 and a second eaves structure 23 are provided at the edges of adjacent sides of each box 20. In addition, a support area 30a is provided at the edges of adjacent sides of each box 20, and the support area 30a is located on the first eaves structure 22.

[0133] Furthermore, unlike the embodiments shown in Figures 4 to 13, in Figures 17 to 20, the first eaves structure 22 may not have an avoidance notch. The support area 30a may also not have a groove.

[0134] In Figures 17 to 20, two adjacent boxes 20 can be detachably connected by fasteners. The specific connection method can be referred to the descriptions in Figures 4 to 13, which will not be repeated here.

[0135] Currently, in the splicing process of splicing display devices, each display component 10 is usually connected to the cabinet 20 in the Z direction. However, this method is inconvenient when splicing products with narrow seams.

[0136] To address this issue, this disclosure provides a splicing display device comprising multiple splicing units 1 connected together, as shown in Figures 2 and 3. Each splicing unit 1 includes a display component 10 and a housing 20 disposed on the non-display side of the display component 10. The structure of the display component 10 can be found in the description of the above embodiments and will not be repeated here.

[0137] Additionally, as shown in Figure 12A, the splicing unit 1 may further include a first magnetic component 50, which includes a first component 51 and a second component 52 capable of magnetic attraction. The first component 51 is disposed on the display component 10, and the second component 52 is disposed on the housing 20. As shown in Figure 24, the housing 20 has a hollow portion 20v extending through the housing 20 along the Z direction. The arrangement of the second component 52 on the housing 20 can be found in the descriptions of Figures 12A and 13 in the above embodiments, and will not be repeated here. Furthermore, in conjunction with Figures 21 to 24, the splicing unit 1 may further include a magnetic adsorption sheet 61, wherein the magnetic adsorption sheet 61 is configured to be rotatably connected to the display component 10, so that the magnetic adsorption sheet 61 is in one of a first state (as shown in Figure 22) and a second state (as shown in Figure 23); in the first state, the magnetic adsorption sheet 61 is disposed opposite to the surface of the display component 10 facing the housing 20.

[0138] In one example, an auxiliary member 62 is provided on the side of the cutout portion 20v. In the second state, the magnetic adsorption piece 61 extends into the cutout portion 20v and magnetically attracts it to the auxiliary member 62. Either the magnetic adsorption piece 61 or the auxiliary member 62 can be made of a ferromagnetic material, such as iron; the other can be a magnet.

[0139] Alternatively, in another example, in the second state, the magnetic adsorption sheet 61 is magnetically attracted to the magnetic adsorption sheet 61 in the adjacent splicing unit 1. In this case, one of the two magnetic adsorption sheets 61 in adjacent splicing units 1 that are close to each other can be made of a ferromagnetic material, such as iron; the other can be made of a magnet.

[0140] In this embodiment of the disclosure, "mutual magnetic attraction" refers to the magnetic force that attracts two components to each other. The two components can be in contact or there can be a certain gap between them.

[0141] In this embodiment of the present disclosure, a magnetic adsorption sheet 61 is provided on the side of the display component 10 facing the housing 20, and the magnetic adsorption sheet 61 can be in a first state or in a second state. Therefore, during the assembly process of the splicing display device, after the multiple housings 20 are assembled, each display component 10 can be placed on the corresponding housing 20 in sequence. By controlling the state of different magnetic adsorption sheets 61, the force direction of the display component 10 can be controlled, thereby making the gap between two adjacent display components 10 sufficiently small. Specifically, taking the magnetic adsorption piece 61 in the second state and the auxiliary component 62 magnetically attracting each other as an example, as shown in Figure 25, assuming that the splicing display device includes two splicing units 1, after splicing the housings 20 of the two splicing units 1, the display component 10 of the left splicing unit is fixed to the housing 20. Then, the magnetic adsorption piece on the left edge of the display component 10 in the right splicing unit is in the second state, and the magnetic adsorption pieces in other positions are in the first state. This causes the magnetic adsorption piece 61 on the left edge of the right display component 10 to generate a magnetic attraction force with the auxiliary component 62 at the opposite position on the housing 20 (as shown by F1 in Figure 25). At the same time, the display component 10 is subjected to a longitudinal gravity force (as shown by F2 in Figure 25). This causes the resultant force on the right display component 10 to move and squeeze tightly with the left display component 10, as shown by F3.

[0142] Similarly, when the auxiliary component 62 is not provided on the cabinet 20, the display component 10 can be moved relative to each other by relying on the magnetic attraction between the magnetic adsorption pieces 61 in the adjacent splicing unit 1.

[0143] For example, as shown in Figures 22 and 23, the splicing unit 1 further includes a mounting component 63, which includes a movable part 632, a fixed part 631, and a rotating shaft 633. The movable part 632 is fixedly connected to the display component 10, and the movable part 632 is rotatably connected to the fixed part 631 via the rotating shaft 633. The rotating shaft 633 extends along the surface of the display component 10 toward the housing 20. The magnetic adsorption sheet 61 is fixed on the movable part 632, thereby achieving an indirect rotatable connection between the magnetic adsorption sheet 61 and the display component 10 by means of the mounting component 63.

[0144] For example, both the movable part 632 and the fixed part 631 can be plate-shaped structures. The fixed part 631 can be connected to the carrier plate 12 of the display assembly 10. For example, the fixed part 631 can be fixed to the carrier plate 12 by welding, bonding, or by screws or other connectors. The magnetic adsorption piece 61 can be fixed to the movable part 632 by bonding, welding, or other methods, or by screws or other connectors. Alternatively, a mounting groove can be provided on the movable part 632, and the magnetic adsorption piece 61 can engage in the mounting groove. This disclosure does not limit the shape of the magnetic adsorption piece 61; it can be circular, elliptical, rectangular, or other irregular shapes.

[0145] For example, multiple splicing units 1 are arranged sequentially in a first direction (hereinafter referred to as the X direction). Specifically, the multiple splicing units 1 can be arranged in an array, with the X direction being the row direction, and the X direction can be perpendicular to the height direction of the splicing display device. The splicing display device can be installed on a wall or other mounting base, and the height direction of the splicing display device is the height direction when the splicing display device is in use. The multiple splicing units 1 can be arranged in one row and multiple columns, or in multiple rows and multiple columns.

[0146] The display component 10 includes a first edge and a second edge disposed opposite to each other in the X direction. Mounting members 63 and magnetic adsorption pieces 61 are disposed near both the first and second edges. The pivot 633 of the mounting member 63 near the first edge extends in the same direction as the first edge, and the pivot 633 of the mounting member 63 near the second edge extends in the same direction as the second edge. Multiple mounting members 63 and multiple magnetic adsorption pieces 61 can be disposed near both the first and second edges.

[0147] Figure 26 shows the force direction of the display components of splicing unit 1 during the assembly process. The force direction of each display component is shown by the arrow in Figure 26. Taking a splicing display device comprising two rows and four columns of splicing units 1 as an example, as shown in Figure 26, during the splicing process, the magnetic adsorption pieces 61 on the left side of each splicing unit 1 in the first and second columns, and the magnetic adsorption pieces 61 on the right side of each splicing unit 1 in the third and fourth columns, are in a first state. The magnetic adsorption pieces 61 on the right side of each splicing unit 1 in the first and second columns, and the magnetic adsorption pieces 61 on the left side of each splicing unit 1 in the third and fourth columns, are in a second state. In this case, after each display component 10 is placed on its corresponding housing 20, the magnetic adsorption between the magnetic adsorption pieces 61 and the corresponding auxiliary components 62, along with the gravity of the display components 10 themselves, causes the display components 10 in each splicing unit 1 in the first and second columns to be subjected to a force in the lower right direction, and the display components 10 in each splicing unit 1 in the third and fourth columns to be subjected to a force in the lower left direction, thereby automatically squeezing the splicing units 1 on the left and right sides of the splicing display device together. This method can improve the installation efficiency of the splicing display device and reduce the installation difficulty.

[0148] In this disclosure, the embodiments shown in Figures 21 to 26 can be combined with the embodiments shown in Figures 4 to 20. Specifically, when a magnetic adsorption sheet 61 is provided on the display component 10, the display component 10 can be supported on the housing 20, or a support area 30a can be provided on the housing 20, and the display component 10 can be supported on the support surface 30 of the support area 30a. The specific overlapping method of the display component 10 on the support area 30a, the connection method between adjacent housings 20, and the connection method between the display component 10 and the housing 20 can all be referred to the description of Figures 4 to 20 above, and will not be repeated here.

[0149] Figure 27 is a schematic diagram of the housing 20 and the adjustment component provided in some embodiments of this disclosure, and Figure 28 is an enlarged view of region M in Figure 27. As shown in Figures 27 and 28, in some embodiments, the housings 20 of multiple splicing units 1 form a load-bearing structure 2. The load-bearing structure 2 is provided with an adjustment component, which is configured to connect the load-bearing structure 2 to the mounting base and adjust the installation position of the load-bearing structure 2 on the mounting base.

[0150] The installation base can be a wall or other structures.

[0151] For example, as shown in Figures 27 and 28, the adjustment assembly includes multiple connectors 80 and multiple sliders 83. Each connector 80 includes a first connecting portion 81 and a second connecting portion 82, the second connecting portion 82 being configured to connect to the mounting base. The first connecting portion 81 has a first guide groove 81v. A portion of the first guide groove 81v on the connectors 80 extends along the X direction, and another portion of the first guide groove 81v on the connectors 80 extends along a second direction (hereinafter referred to as the Y direction). The X and Y directions intersect and are both perpendicular to the Z direction; for example, the X direction is perpendicular to the Y direction. Each slider 83 corresponds one-to-one with a first guide groove 81v. The slider 83 is slidably disposed in the corresponding first guide groove 81v (i.e., the slider 83 can undergo relative displacement with the connector 80 along the extension direction of the first guide groove 81v) and is fixedly connected to the bearing structure 2.

[0152] For example, the first guide groove 81v can be a through groove that passes through the second connecting part 82 along the Z direction, and the slider 83 can be a screw that passes through the first guide groove 81v.

[0153] For example, the first connecting part 81 and the second connecting part 82 can be plate-like structures, and the two can be connected as a single structure. Of course, the first connecting part 81 and the second connecting part 82 can also be connected by other connectors.

[0154] In this embodiment, by controlling the sliding member 83 to move along the first guide groove 81v, the bearing structure 2 is displaced relative to the connecting member 80, thereby adjusting the installation position of the bearing structure 2 on the mounting base; compared with the bracket behind the traditional housing 20, the connecting member 80 and the sliding member 83 have simple structures and are easy to install and implement.

[0155] For example, the support structure 2 includes two third edges disposed opposite to each other in the X direction and two fourth edges disposed opposite to each other in the Y direction. Each third edge and each fourth edge is provided with a connector 80. A first guide groove 81v on the connector 80 of the third edge extends in the X direction, and a first guide groove 81v on the connector 80 of the fourth edge extends in the Y direction.

[0156] In this embodiment, the number of connectors 80 provided at each third edge and each fourth edge is not limited. In one example, to improve the installation stability of the load-bearing structure 2, multiple connectors 80 may be provided at each third edge and each fourth edge.

[0157] For example, as shown in Figure 28, a second guide groove 82v is provided on the second connecting portion 82, and the second guide groove 82v extends along the Z direction. The second guide groove 82v can penetrate along the thickness direction of the second connecting portion 82. In practical applications, screws can be inserted into the second guide groove 82v and connected to the mounting base, thereby mounting the second connecting portion 82 onto the mounting base. Since the second guide groove 82v extends along the Z direction, the second connecting portion 82 can move relative to the mounting base along the Z direction, thereby adjusting the position of the splicing display device in the Z direction.

[0158] In this disclosure, the embodiments shown in Figures 27 and 28 can be combined with the embodiments shown in Figures 4 to 26. Specifically, when an adjustment component is provided on the supporting structure 2, the display component 10 can be supported on the housing 20, or a support area 30a can be provided on the housing 20, and the display component 10 can be supported on the support area 30a. For a specific implementation of the display component 10 overlapping the support area 30a, please refer to the description of Figures 4 to 20 above. A first eaves structure 22 can be provided on the housing 20, or both a first eaves structure 22 and a second eaves structure 23 can be provided simultaneously, as detailed in the description of Figures 4 to 20 above. Additionally, when an adjustment component is provided on the supporting structure 2, a magnetic adsorption sheet can also be provided on the display component 10, as detailed in the description above.

[0159] 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.
