Description

Technical Field

[0001] The present application belongs to the technical field of COB display screens, and more specifically, relates to a connection component and a display device. Background Art

[0002] COB (Chip On Board) display is a large-size screen composed of multiple display modules. When in use, each display module displays a different image or color, which is then combined into a complete display screen. It is widely used in commercial advertising, conference presentations, stage performances and other fields.

[0003] Because assembled large-scale screens are difficult to transport, display modules generally need to be transported to the installation site for splicing and assembly. Currently, adjacent display modules are typically connected using magnetic or screw connections during the installation process. While magnetic connections offer high assembly efficiency, the magnets are expensive and easily attract metallic foreign matter, and their limited suction force makes it difficult to ensure seamless splicing of large-scale display modules. Screw connections rely on specialized tools, resulting in low installation efficiency and difficulty tightening or removing screws at the installation site due to the lack of back access.

[0004] Therefore, the existing COB display screen has the defects of low splicing efficiency and poor splicing accuracy. Summary of the Invention

[0050] Reference Figures 1-15 An embodiment of the present application provides a display device, including a display component 100, a connection component 200, a hanging bracket component 400 and an edge-binding component 300.

[0051] Reference Figure 1 、 Figure 2 and Figure 3 The display assembly 100 includes a plurality of display units 110 arranged along a first direction, and the display unit 110 includes a plurality of display modules 101 arranged along a second direction, with the first direction being perpendicular to the second direction. In this embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction. That is, a certain number of display modules 101 are first arranged and interconnected in a vertical direction to form the display unit 110, and then multiple display units 110 are arranged and interconnected in a horizontal direction to form the entire display assembly 100, so that the entire display assembly 100 is composed of multiple display modules 101 arranged in a matrix. Two adjacent display units 110 are connected and fixed by at least one connecting assembly 200.

[0052] In actual applications, a predetermined number of display modules 101 can be spliced ​​along the second direction at the factory to form a plurality of display units 110. Each display unit 110 is in a long strip shape and has a size suitable for transportation. The plurality of display units 110 are then transported to the installation site, where they are spliced ​​along the first direction using the connecting assembly 200 to form the entire display assembly 100. The edging assembly 300 and the hanging bracket assembly 400 are then sequentially installed, thereby reducing the difficulty of assembly at the installation site and improving work efficiency.

[0053] The display module 101 is used to display images and may include a housing and components such as a screen, a backlight module, and a drive circuit disposed therein. The display module 101 has a display surface 101a and a backlight surface 101b that face each other in a third direction. Both the first and second directions are perpendicular to the third direction. In this embodiment, the third direction is a horizontal direction perpendicular to the first direction. The display surface 101a is the front surface of the display module 101, and the backlight surface 101b is the back surface of the display module 101. The display surface 101a is used to display images, and the backlight surface 101b is used to connect to components such as the hanger assembly 400.

[0054] Reference Figure 4 The display module 101 further has two first connecting surfaces 101c facing each other in the second direction. The two first connecting surfaces 101c can be arranged symmetrically. When multiple display modules 101 are connected to form a display unit 110 along the second direction, the two first connecting surfaces 101c facing each other in two adjacent display modules 101 in the second direction abut against each other.

[0055] Both first connection surfaces 101c may be provided with a first connection structure, which is used to securely connect two adjacent display modules 101 in the second direction. The first connection structure may include a snap-fit ​​structure, a bolt connection structure, or a magnetic connection structure, etc., to position and connect the display modules 101 in the second direction, thereby stabilizing the structure of the pre-assembled display unit 110.

[0056] Furthermore, electrical connection structures may be provided on the two first connection surfaces 101c, so that when two adjacent display modules 101 in the second direction are connected, the internal circuits are electrically connected via the electrical connection structures, thereby achieving continuous display of images on each display module 101. The electrical connection structures may be pluggable electrical connectors, elastic contact sheets, or any other structural form capable of transmitting electrical signals.

[0057] The display module 101 further has two second connection surfaces 101d facing each other in the first direction. When multiple display units 110 are connected along the first direction to form the display assembly 100, in two adjacent display modules 101 in the first direction, the two facing second connection surfaces 101d abut against each other.

[0058] A second connection structure may also be provided on the two second connection surfaces 101d to position the mutual connection between the two adjacent display units 110, ensure the relative position of the display modules 101 at the same height in the two adjacent display units 110, and further ensure the continuity and accuracy of the image display on the entire display assembly 100.

[0059] For example, one of the second connection surfaces 101d has a protruding positioning post, and another second connection surface 101d has a positioning hole. The positioning hole and the positioning post have matching shapes, and the orthographic projection of the positioning post on the fourth connection surface falls within the positioning hole. When two adjacent display units 110 are spliced ​​together in the first direction, the positioning post can be accurately inserted into the positioning hole facing the adjacent display units 110, thereby achieving the desired positional alignment of the two adjacent display units 110 in the first direction. The number of positioning posts and positioning holes can be one or more.

[0060] The connecting assembly 200 is disposed between two adjacent display units 110 and is used to apply a force to push the two display units 110 toward each other, thereby achieving a stable connection between the two display units 110. Specifically, the connecting assembly 200 can be connected between two display modules 101 adjacent in a first direction in two adjacent display units 110. For example, the connecting assembly 200 can be used to connect two display modules 101 located at the sides of two display units 110.

[0061] Reference Figure 5-Figure 8The connection assembly 200 includes a locking structure and a tightening member 220. The locking structure includes two locking members 210, each for connecting to a corresponding display unit 110. The locking members 210 have first guide slopes 2111. The first guide slopes 2111 on the two locking members 210 are arranged in a first direction and are disposed opposite each other. The spacing between the first guide slopes 2111 on the two locking members 210 in the first direction gradually increases along the driving direction. The tightening member 220 has two second guide slopes 2211 facing each other. The two second guide slopes 2211 are arranged in the first direction. The spacing between the two second guide slopes 2211 in the first direction gradually increases along the driving direction.

[0062] Each second guide slope 2211 can slide and abut against the corresponding first guide slope 2111. When the tightening member 220 moves toward the two locking members 210 along the driving direction, the first guide slope 2111 and the second guide slope 2211 slide relative to each other, applying a locking force to the two first guide slopes 2111 that drives the two locking members 210 toward each other in the first direction, thereby applying a locking force to the two display units 110. The driving direction is perpendicular to the first direction. In this embodiment, the driving direction is parallel to the third direction and is the direction in which the tightening member 220 moves toward the locking structure.

[0063] The locking member 210 can be a block or rod-shaped component of any shape. In this embodiment, the locking member 210 is a block structure extending along the first direction. The locking member 210 can be connected to any position of the display unit 110. In this embodiment, the locking member 210 is connected to the end of the display unit 110 in the second direction, that is, the locking member 210 is connected to the uppermost or lowermost display module 101 in the display unit 110, so as to facilitate operation of the connection assembly 200 during installation. Specifically, the locking member 210 can be connected to the first connecting surface 101c of the topmost or bottommost display module 101 in the display unit 110. The connection between the locking member 210 and the first connecting surface 101c can be a combination of any one or more methods such as plug-in connection, snap-fit ​​connection, and bolt connection, so that when the two locking members 210 slide toward each other, they drive the two display modules 101 closer to each other, that is, a locking force in the first direction is applied to the two display modules 101, thereby realizing rapid connection of two adjacent display units 110 in the first direction.

[0064] In this embodiment, a hook portion 212 is protruded from one side of the locking member 210 facing the display module 101 , and a hook groove 1011 is formed on the surface of the display module 101 facing the locking member 210 . The hook portion 212 on each locking member 210 is hooked into the corresponding hook groove 1011 on the display module 101 .

[0065] The hook portion 212 may be an L-shaped protrusion protruding from one side of the locking member 210, with its end facing away from the locking member 210 forming a hook head that bends toward the body of the locking member 210. The hook groove 1011 is a groove structure that matches the shape of the hook portion 212. The hook groove 1011 may be provided on the first connecting surface 101c of the display module 101. When multiple display modules 101 are connected along the second direction to form the display unit 110, the top or bottom end surface of the display unit 110 will each have a hook groove 1011 that mates with the hook portion 212, thereby enabling connection of the locking member 210 to the top or bottom end surface of the display unit 110. It can be understood that each first connecting surface 101c should be provided with at least two hooking grooves 1011, and the two hooking grooves 1011 are respectively located on both sides of the first connecting surface 101c in the first direction, so that one connecting component 200 can be used on both sides of the display unit 110 to connect to the adjacent display unit 110.

[0066] The first guide slope 2111 is an inclined surface on the locking member 210. In some embodiments, a guide groove 211 may be defined on the side of the locking member 210 facing the tightening member 220. The adjacent sidewalls of the two guide grooves 211 on the two locking members 210 are inclined to form the first guide slopes 2111 on the two locking members 210. The inclination angle of the first guide slope 2111 may be 30° to 60° to ensure smooth sliding between the first guide slope 2111 and the second guide slope 2211 and moderate locking force.

[0067] The tightening member 220 can also be a block or rod-shaped structure of any shape. In this embodiment, the tightening member 220 is a rectangular block extending along the first direction. The second guide slopes 2211 are inclined wall surfaces on the tightening member 220. The positions of the two second guide slopes 2211 correspond to the positions of the first guide slopes 2111 on the two locking members 210, and the inclination angles of the second guide slopes 2211 are the same as the inclination angles of the first guide slopes 2111.

[0068] In this embodiment, two protrusions 221 are provided on the side of the tightening member 220 facing the locking member 210. The two sidewalls of the two protrusions 221 facing each other are inclined relative to the tightening member 220 to form two second guide slopes 2211. The two protrusions 221 may be located at the two extending ends of the tightening member 220, respectively. The protrusions 221 can be inserted into corresponding guide slots 211 along the driving direction of the tightening member 220. The guide slots 211 are provided on a side of the locking member 210 facing away from the display module 101, with the notches of the guide slots 211 facing the tightening member 220. As the tightening member 220 moves toward the locking member 210, the protrusions 221 gradually insert into the guide slots 211, causing the second guide slopes 2211 to slide against the first guide slopes 2111, thereby driving the two locking members 210 to slide in the first direction. This structure enables the tightening member 220 to act more stably on the locking member 210 when moving, thereby improving the connection stability and reliability of the connection assembly 200.

[0069] In some embodiments, the connecting assembly 200 further includes a driving member 230 , which is in driving connection with the tightening member 220 and is configured to drive the tightening member 220 to move toward or away from the two locking members 210 .

[0070] The driving member 230 is a component capable of generating a driving force, causing the tightening member 220 to undergo linear reciprocating motion under the action of the driving force, thereby driving the two locking members 210 to move. In this embodiment, the driving member 230 is a bolt, comprising a screw portion 231 and a nut portion 232 connected to one end of the screw portion 231. The tightening member 220 has a first threaded hole 2201 defined between the two raised portions 221, with the screw portion 231 being threadedly connected to the first threaded hole 2201. The nut portion 232 may be provided with a rotation groove in a cross, straight, or plum blossom shape, for facilitating rotation of the nut portion 232 using a tool such as a screwdriver.

[0071] The two locking members 210 are each provided with a bar hole 213 extending in the first direction at one end thereof, stacked in the driving direction, with at least a portion of the bar holes 213 overlapping and communicating with each other. A screw portion 231 is disposed within the two bar holes 213, and a nut portion 232 is located on the side of the locking structure facing away from the locking members 210 and abuts against the locking member 210 farther from the tightening member 220. The screw portion 231 and nut portion 232 serve to limit and support the two locking members 210, thereby stabilizing the relative position of the two locking members 210 and the tightening member 220. Among them, grooves can be provided at the ends of the two locking parts 210 that are close to each other. The grooves on the two locking parts 210 are axially symmetrical and slide with each other so that the two locking parts 210 are flush with each other. During the sliding cooperation process, the two locking parts 210 can maintain parallel and stable movement, while facilitating the connection between the two locking parts 210 and the display modules 101 on both sides.

[0072] When the screw portion 231 is rotated by the nut portion 232, the nut portion 232 is pressed against the locking member 210, and the positions of the locking member 210 and the display module 101 are relatively fixed. Thus, the screw portion 231 can drive the tightening member 220 to move toward the two locking members 210 until the protrusion 221 is completely embedded in the guide groove 211 and the second guide slope 2211 is tightly abutted against the first guide slope 2111. At this point, the two locking members 210 approach each other in the first direction, and the hook portion 212 is tightly hooked in the hook groove 1011, thereby achieving a stable connection to the display unit 110. Due to the provision of the bar hole 213, the locking member 210 and the screw portion 231 can slide relative to each other for a certain distance in the first direction without interfering with the movement of the locking member 210.

[0073] Reference Figure 6During actual construction, the two display units 110 are first joined together along the first direction. The two locking members 210 in the connection assembly 200 are then hooked into the hooking slots 1011 of the two display units 110. At this point, the first guide bevels 2111 on the two locking members 210 and the second guide bevels 2211 on the tightening member 220 slide against each other, but no locking force is applied to the two display units 110. Subsequently, the tightening member 220 is moved toward the two locking members 210 by turning the bolt. During this movement, the first and second guide bevels 2111, 2211, slide relative to each other. As the spacing between the first and second guide bevels in the first direction gradually decreases, the two locking members 210 are driven toward each other in the first direction. During this process, the hooking portions 212 on the locking members 210 slide within the hooking slots 1011, applying a thrust to the display module 101, thereby applying a locking force that brings the two display units 110 closer together. Conversely, rotating the bolt in the opposite direction causes the tightening member 220 to move away from the two locking members 210. Once the two locking members 210 are no longer restrained by the tightening member 220, they can move away from each other in the first direction, thereby releasing the lock on the two display units 110 and facilitating disassembly or adjustment of the display assembly 100. Because the threaded connection between the screw portion 231 and the tightening member 220 is self-locking, the tightening member 220 maintains its current position after rotation stops, preventing the locking force of the two locking members 210 from being weakened due to external interference.

[0074] Among them, the nut part 232 of the bolt can be located on the side of the locking part 210 facing the display surface 101a of the display module 101, and the tightening part 220 is located on the side of the locking part 210 facing the backlight surface 101b of the display module 101. When splicing multiple display units 110 at the installation site, the staff only needs to rotate the nut part 232 on the side of the display surface 101a to achieve the connection between two adjacent display units 110. The staff has a larger working space, which improves the convenience of on-site construction operations.

[0075] Reference Figure 9 In another embodiment, a limiting groove 214 is provided on the side wall of at least one guide groove 211, and a limiting portion 222 is provided on the protrusion 221, and the limiting portion 222 is slidably connected in the limiting groove 214 along the driving direction.

[0076] The limiting groove 214 is a groove structure formed on the inner wall of the guide groove 211. The limiting groove 214 can be located on the inner wall of the guide groove 211 facing away from the first guide inclined surface 2111. The limiting portion 222 is a protrusion structure protruding from the protrusion 221 toward the limiting groove 214. The limiting portion 222 is embedded in the limiting groove 214. The length of the limiting groove 214 in the direction of movement of the tightening member 220 (in the axial direction of the screw portion 231) is greater than the thickness of the limiting portion 222, so that the limiting portion 222 can slide within the limiting groove 214.

[0077] The cooperation between the limiting groove 214 and the limiting portion 222 can play a role in limiting the distance of the relative displacement of the tightening member 220 and the locking member 210, thereby preventing the protrusion 221 from being separated from the guide groove 211 when the tightening member 220 moves away from the locking member 210, maintaining the overall structure of the entire connecting component 200, and making it less likely for the connecting component 200 to be scattered or lost during the disassembly process, thereby improving the reliability and durability of the connecting component 200.

[0078] Furthermore, the connecting assembly 200 may also include an elastic member, which is connected between at least one locking member 210 and the tightening member 220. The elastic member can generate a reset force that drives the tightening member 220 to move in the opposite driving direction when the tightening member 220 moves toward the locking member 210, so as to drive the tightening member 220 away from the two locking members 210.

[0079] The elastic member can be a spring 240 or an elastic rubber structure, with its ends fixed to corresponding connection points of the locking member 210 and the tightening member 220. In this embodiment, the elastic member is a spring 240, which is disposed between the locking member 210 and the tightening member 220, near the tightening member 220. Furthermore, the locking member 210 has a receiving groove 215 on the side facing the tightening member 220, and the spring 240 is located within the receiving groove 215, making the overall structure more compact.

[0080] When the bolt rotates forward and drives the tightening member 220 to move toward the locking member 210, the spring 240 is compressed and stores elastic potential energy; when the bolt rotates in the reverse direction, the spring 240 continuously applies a thrust to the tightening member 220 to move away from the locking member 210, and keeps the nut portion 232 of the bolt pressed against the locking member 210, so that the tightening member 220 can gradually move away from the locking member 210 as the bolt is reversed, and then, under the action of the first guide bevel 2111 and the second guide bevel 2211, the two locking members 210 are driven to move away from each other, thereby releasing the locking force on the two display modules 101.

[0081] Reference Figure 1 and Figure 10 The edging component 300 is used to surround the peripheral side of the display component 100, shielding the side walls of the display modules 101 located at the edge of the display component 100, thereby further strengthening the structure of each display module 101 in the display component 100 and beautifying the overall appearance.

[0082] In some embodiments, the edge-wrapping assembly 300 includes a first edge-wrapping assembly 310 and a plurality of second edge-wrapping assembly 320. The first edge-wrapping assembly 310 and the plurality of second edge-wrapping assembly 320 are disposed together around the periphery of the display assembly 100, and the first edge-wrapping assembly 310 has a receiving chamber 3111. The display device further includes an electronic component disposed within the receiving chamber 3111.

[0083] The total number of first and second edge wrappings 310, 320 is the same as the number of sidewalls surrounding the display assembly 100. The first edge wrapping 310 and the plurality of second edge wrappings 320 are respectively connected to different positions of the display assembly 100 and can be adapted to the installation requirements of the display assembly 100. In this embodiment, the display assembly 100 is generally rectangular and has four sidewalls. The edge wrapping assembly 300 includes a first edge wrapping 310 and three second edge wrappings 320. The first edge wrapping 310 is mounted on the bottom surface of the display assembly 100, and the three second edge wrappings 320 are respectively mounted on the top surface and left and right side surfaces of the display assembly 100.

[0084] The accommodating chamber 3111 is a hollow structure provided within the first edge 310 and is used to house the electronic components required by the display assembly 100. Electronic components are electronic devices used to control the display of the display module 101 or perform other related operations within the display device, such as an audio module for playing audio or a wireless communication module for wireless communication with the display assembly 100. Electronic components can also be cable circuits used to electrically connect two adjacent display units 110. The provision of the accommodating chamber 3111 within the first edge 310 provides installation space for the electronic components used with the display assembly 100, facilitating their installation and maintenance.

[0085] Reference Figure 11 and Figure 12 In some embodiments, the first edging 310 may include multiple edging boxes 311 and at least one cover plate 312. The multiple edging boxes 311 correspond one-to-one to the multiple display units 110, and each edging box 311 is connected to a corresponding display unit 110. The accommodating chamber 3111 is disposed in the edging box 311, and the edging box 311 further has an opening connecting the accommodating chamber 3111 with the external space. The cover plate 312 is detachably connected to the multiple edging boxes 311 and seals the opening on each edging box 311, so as to facilitate the installation, maintenance, or replacement of the electronic components in the accommodating chamber 3111.

[0086] Among them, the edging box 311 refers to an independent shell structure that matches the number of display units 110. The interior of the edging box 311 is hollow to form a accommodating chamber 3111, and the edging box 311 can be opened on both sides in the first direction so that the accommodating chambers 3111 of two adjacent edging boxes 311 can be connected to each other, which is convenient for the installation and arrangement of electronic components in the accommodating chamber 3111.

[0087] The edging box 311 can be fixed to the side of the display unit 110 by means of a snap or bolt connection. The edging box 311 can be connected to the bottom display module 101 when multiple display modules 101 are spliced ​​together to form the display unit 110. After transportation to the installation site, the multiple display units 110 are spliced ​​together to form the copper lock of the display assembly 100. The multiple edging boxes 311 are also connected to each other to form the first edging 310. After the electronic components in the accommodating chamber 3111 are installed, the cover plate 312 is then placed on the multiple edging boxes 311 to seal the cavities on each edging box 311, protecting the electronic components inside while ensuring the structural beauty of the first edging 310.

[0088] The cover plate 312 and the edge binding box 311 can be detachably connected by means of bolts, snaps, or magnets 3112. The number of cover plates 312 can be the same as the number of edge binding boxes 311, and each cover plate 312 is respectively covered on one edge binding box 311. Alternatively, a single cover plate 312 can be provided, and the cover plate 312 is simultaneously covered on multiple edge binding boxes 311 to close the openings of all the edge binding boxes 311.

[0089] In some embodiments, the edging box 311 can be connected to the cover plate 312 by magnetic attraction 3112. Specifically, a magnet can be connected to one side of the edging box 311 and the cavity opening, and the cover plate 312 can be made of a magnetic metal material, such as iron, nickel, cobalt, or an alloy thereof, or an adsorption plate made of a magnetic metal can be provided on the side of the cover plate 312 facing the edging box 311, so that the cover plate 312 can be directly magnetically attracted 3112 and snapped together at the cavity opening of the edging box 311, making it convenient for staff to quickly install and remove the cover plate 312, thereby improving the efficiency of installation and maintenance.

[0090] In some embodiments, the electronic component includes multiple connecting cables, and the multiple connecting cables correspond one-to-one to the multiple edge boxes 311. Each connecting cable is respectively arranged in the accommodating chamber 3111 of each edge box 311 and is electrically connected to the corresponding display unit 110; in the first direction, the cables in two adjacent edge boxes 311 are electrically connected to electrically connect the two adjacent display units 110.

[0091] A connecting cable is a conductor used to transmit electrical signals or electrical energy. In this embodiment, the connecting cables include a signal cable 102 and a power cable 103. The signal cable 102 is used to transmit display data or other control signals, while the power cable 103 is used to provide power to the display unit 110. Each connecting cable in the edging box 311 is electrically connected to the corresponding display unit 110. The connecting cables can be pre-installed in the display module 101, or interfaces for connecting to the connecting cables can be reserved on the surface of the display module 101. When pre-assembling each display unit 110, corresponding connecting cables can be reserved in the edging box 311. After the display units 110 are spliced ​​together to form the display assembly 100, the connecting cables in two adjacent edging boxes 311 are electrically connected to enable communication or shared power supply between the two adjacent display units 110, further improving the convenience of on-site installation.

[0092] Reference Figure 13 In some embodiments, the second edging 320 may include an edging plate 321 and at least one elastic buckle 322. The extension direction of the edging plate 321 is parallel to the extension direction of the corresponding side of the display component 100. The elastic buckle 322 is arranged on the side of the edging plate 321 facing the display component 100. The side wall of the display component 100 facing the display module 101 is provided with a plug hole 1012, and the elastic buckle 322 is elastically plugged into the plug hole 1012.

[0093] The edging plate 321 is a plate-like structure that covers the sides of the display assembly 100. It extends parallel to the sides of the display assembly 100, providing support and protection for the sides. The elastic buckle 322 is an elastically deformable plug-in component, such as a bent elastic metal column.

[0094] The insertion holes 1012 are through-hole structures defined on the sidewalls of the display module 101. Their location and number match those of the elastic buckles 322. In this embodiment, two insertion holes 1012 are defined on both the first connection surface 101c and the second connection surface 101d of the display module 101. The shape of the insertion holes 1012 matches that of the elastic buckles 322. The width of the elastic buckles 322 gradually decreases as it moves away from the edging plate 321, facilitating insertion of the elastic buckles 322 into the insertion holes 1012. The maximum width of the elastic buckles 322 can be greater than the width of the insertion holes 1012.

[0095] During installation, the edging plate 321 is placed close to the side of the display module 100 and pressed, causing the head of the elastic buckle 322 to deform under pressure and enter the insertion hole 1012. After passing through the insertion hole 1012, the elastic buckle 322 returns to its original shape, with its wider head being stuck at the inner edge of the insertion hole 1012, thus completing the mechanical locking of the edging plate 321 and the display module 101. During disassembly, the edging plate 321 can be separated by applying reverse force to deform the elastic buckle 322 again, which has the advantages of simple structure and convenient installation.

[0096] Reference Figure 10 and Figure 14 , the rack assembly 400 is used to be installed at the installation position of the display device; the backlight surface 101b of at least one display module 101 is provided with a hook 120, and the hook 120 is hung on the rack assembly 400.

[0097] The bracket assembly 400 refers to a support structure fixed to the installation position of the display device, and the bracket assembly 400 can be a frame-type support structure or a hanging rod-type structure. Figure 15 In this embodiment, the hanger assembly 400 includes two horizontal beams 410 and two vertical beams 420. The two horizontal beams 410 extend parallel to each other in a first direction, and the two vertical beams 420 are respectively connected to the ends of the two horizontal beams 410 to form the hanger assembly 400 with a rectangular frame structure. The horizontal beams 410 and adjacent vertical beams 420 can be connected by fastening bolts 430. Specifically, the extended ends of the horizontal beams 410 can be provided with second threaded holes 4101, and the vertical beams 420 can be provided with bolt holes 4201 in portions corresponding to the extended ends of the horizontal beams 410. The axes of the bolt holes 4201 and the second threaded holes 4101 coincide with each other. The fastening bolts 430 are inserted into the bolt holes 4201 and the second threaded holes 4101, thereby fixedly connecting the horizontal beams 410 and the vertical beams 420.

[0098] The mounting location for securing the display device can be a wall, column, or other stable building structure, or a dedicated mounting bracket. The horizontal beam 410 may be provided with a plurality of first mounting holes 4102 for fasteners such as expansion bolts to secure the bracket assembly 400 to the mounting location. The vertical beam 420 may also be provided with a plurality of second mounting holes 4202 for other types of bolts to secure the bracket assembly 400 to the dedicated mounting bracket.

[0099] The hook 120 can be an L-shaped metal hook with a bending angle that matches the cross-sectional shape of the crossbeam 410 of the hanger assembly 400. The crossbeam 410 in the hanger assembly 400 can be designed as a guide rail structure with a transverse slide groove, allowing the hook 120 to be finely adjusted in the horizontal direction. The hook 120 can be connected to the backlight surface 101b of the display module 101 by bolts, welding, or other fixing methods to ensure a secure connection. In this embodiment, the backlight surface 101b of the display module 101 is provided with a plurality of fixing holes 1013, which can be used to fix the hook 120 to the backlight surface 101b using bolts.

[0100] When installing the display device, after the operator assembles the display component 100, he can install the hook 120 at the corresponding position on the display component 100, and then hang the hook 120 on the beam 410 of the bracket component 400 to achieve stable installation of the display device. The installation process is simple and quick, and can be adjusted according to different installation environments, which improves the flexibility and adaptability of the installation.

[0101] Reference Figure 10 In some embodiments, the display device may further include a control component 500 , which is disposed in the display component 100 or on the backlight surface 101 b of any one or more display modules 101 .

[0102] The control assembly 500 is an electronic module used to control the display assembly 100. The control assembly 500 may include a control box and a circuit board mounted therein. The circuit board integrates a control chip and other necessary electronic components used to control the display of the display module 101. The control assembly 500 can be electrically connected to each display module 101 and the electronic components in the display assembly 100 via cables to implement functions such as controlling the display content of the display module 101, adjusting the display brightness, and receiving external signal input.

[0103] The setting position of the control component 500 can be flexibly adjusted according to the actual needs and installation space of the display device. In this embodiment, the control component 500 is installed on a column of display units 110 near the side, and the connecting cables on the display units 110 are electrically connected to the control component 500, so that the control component 500 can uniformly control all display modules 101 in the entire display component 100. The setting of the control component 500 is not only convenient for operation and maintenance, but also ensures the overall aesthetics of the display device. Furthermore, the control component 500 can be designed as a detachable structure to facilitate replacement or upgrading according to actual needs.
