Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a display module and display screen. Background Technology

[0002] Currently, LED displays use high-precision die-cast cabinets to ensure overall flatness. While this approach is effective, the high manufacturing cost of the die-cast cabinets makes them unsuitable for small displays or installations with limited budgets. To address this, existing technologies have employed steel structures as the back frame, with the display modules magnetically attached to the steel structure surface. However, the flatness of this approach depends heavily on the machining precision and installation of the steel structure. Since the flatness of steel structures typically has significant tolerances, this solution still suffers from low module flatness and uneven seams. Utility Model Content

[0003] The main purpose of this utility model is to provide a display module to solve the problems of low flatness and uneven seams in existing steel structure display modules after assembly.

[0004] To achieve the above objectives, this utility model proposes a display module, comprising:

[0005] At least two display units, each display unit having a first splicing side and a second splicing side arranged back to back, the first splicing side having a protruding magnetic snap-fit ​​part; the second splicing side having a snap-fit ​​groove matching the snap-fit ​​part, the snap-fit ​​groove having a connector, the magnetic snap-fit ​​part being embedded in the snap-fit ​​groove and magnetically engaging with the connector, so that the two display units are spliced ​​together.

[0006] Optionally, the magnetic snap-fit ​​part includes a boss and a magnet. The boss protrudes from the first splicing side, and the magnet is disposed on the boss. At least part of the boss can be snapped into the snap-fit ​​groove so that the magnet and the connector are magnetically attracted to each other.

[0007] Optionally, the boss has a mounting groove, and the magnet is at least partially accommodated in the mounting groove.

[0008] Optionally, the end face of the magnet is exposed in the mounting groove, and the connector is disposed at the bottom of the snap-fit ​​groove so that the end face of the connector magnetically engages with the end face of the magnet.

[0009] Optionally, the boss is an arc-shaped boss, the snap-fit ​​groove is an arc-shaped groove, and the arc-shaped boss matches the arc-shaped groove.

[0010] Optionally, the display unit includes a bottom shell and a display panel, the display panel being disposed on the bottom shell, and the boss and the snap-fit ​​groove being integrally formed with the bottom shell.

[0011] Optionally, the magnetic latching portion and the latching groove extend along the thickness direction of the display unit, but do not extend to the display surface of the display unit.

[0012] Optionally, the display unit includes a plurality of magnetic snap-fit ​​parts and a plurality of snap-fit ​​slots, which are disposed opposite to each other on the first splicing side or the second splicing side.

[0013] Optionally, a plurality of magnetic snap-fit ​​portions are spaced apart along the first splicing side, and a plurality of snap-fit ​​slots are spaced apart along the second splicing side, with each magnetic snap-fit ​​portion corresponding to each snap-fit ​​slot.

[0014] This utility model also proposes a display screen, including the above-mentioned display module.

[0015] In this invention, the display module includes at least two display units. Each display unit has a first splicing side and a second splicing side arranged back-to-back. The first splicing side has a protruding magnetic snap-fit ​​part, and the second splicing side has a snap-fit ​​groove that matches the magnetic snap-fit ​​part. A connector is provided in the snap-fit ​​groove. When adjacent display modules are spliced, the magnetic snap-fit ​​part of one display unit snaps into the snap-fit ​​groove of the other display unit and magnetically attracts each other with the connector. The magnetic connection tightly splices the two display units together, eliminating gaps at the splicing point. At the same time, the mutual engagement of the magnetic snap-fit ​​part and the snap-fit ​​groove also plays a guiding and positioning role, ensuring that the display surfaces of adjacent display units are flush after splicing, thus guaranteeing the display effect.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figures 1 to 7 As shown, in one embodiment of the present invention, a display module 100 includes at least two display units 10. Each display unit 10 has a first splicing side 10a and a second splicing side 10b arranged back to back. The first splicing side 10a is provided with a magnetic snap-fit ​​part 20. The second splicing side 10b is provided with a snap-fit ​​groove 30 that matches the snap-fit ​​part. A connector 40 is provided in the snap-fit ​​groove 30. The magnetic snap-fit ​​part 20 is embedded in the snap-fit ​​groove 30 and magnetically attracted to the connector 40 so that the two display units 10 are spliced ​​together.

[0030] In the technical solution of this utility model, the display module 100 includes at least two display units 10. Each display unit 10 has a first splicing side 10a and a second splicing side 10b arranged back-to-back. The first splicing side 10a has a protruding magnetic snap-fit ​​portion 20, and the second splicing side 10b has a snap-fit ​​groove 30 that matches the magnetic snap-fit ​​portion 20. A connector 40 is provided within the snap-fit ​​groove 30. When adjacent display units 10 are spliced, the magnetic snap-fit ​​portion 20 of one display unit 10 snaps into the snap-fit ​​groove 30 of the other display unit 10 and magnetically attracts it to the connector 40. This magnetic connection tightly splices the two display units 10 together, eliminating gaps at the splicing point. Simultaneously, the mutual engagement of the magnetic snap-fit ​​portion 20 and the snap-fit ​​groove 30 also serves a guiding and positioning function, ensuring that the display surfaces 12a of adjacent display units 10 are flush after splicing, thus guaranteeing the display effect.

[0031] It should be noted that the magnetic snap-fit ​​part 20 in this embodiment is provided on the first splicing side 10a of the display unit 10. The magnetic snap-fit ​​part 20 can be in the form of a mounting base being provided on the first splicing side 10a and a magnet 22 or the like being provided on the mounting base; or it can be a protrusion being formed on the display unit 10 and a magnetic coating layer being coated on the surface of the protrusion; or it can be that the magnet 22 or the like is fixed on the first splicing side 10a and the magnetic snap-fit ​​part 20 is directly formed. This embodiment is not limited to these, and all of the above are within the protection scope of this utility model. In this embodiment, the snap-fit ​​groove 30 is located on the second splicing side 10b of the display unit 10. The connector 40 can be a permanent magnet such as neodymium iron boron or ferrite, which has the opposite magnetic properties to the magnetic snap-fit ​​part 20. It can also be a metal such as iron, nickel, or steel that can be magnetically attracted by the magnetic snap-fit ​​part 20. The connector 40 can be detachably installed in the snap-fit ​​groove 30 by means of threaded connection, glue adhesion, snap-fit ​​connection, etc. Magnetic coating layer can also be coated on the groove wall of the snap-fit ​​groove 30 to form the connector 40. As long as the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 can be magnetically connected, this embodiment is not limited to this. All of the above are within the protection scope of this utility model. It should be noted that the depth of the slot 30 should be greater than or equal to the insertion length of the magnetic snap-fit ​​part 20, and the position of the magnetic snap-fit ​​part 20 on the first splicing side 10a should correspond to the position of the slot 30 on the second splicing side 10b. This ensures that when two display units 10 are spliced, the magnetic snap-fit ​​part 20 of one display unit 10 can be completely snapped into the slot 30 of the other display unit 10, and the bottom shells 11 of both units can fit tightly together, ensuring that there are no gaps at the splicing point after the display units 10 are spliced. In this configuration, multiple display units 10 are spliced ​​together to form a flat display module 100, which is then laid on the steel structure. Free positioning can be achieved through the magnetic cooperation of the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30. During installation, precise alignment is not required; they only need to be roughly close together, and the display units 10 can be spliced ​​together by magnetic force. This means that the flatness of the display unit 10 no longer depends on the steel structure, and there is no need to consider the processing precision of the steel structure. This can eliminate the error caused by the unevenness of the steel structure itself, ensuring the display effect of the display module 100.

[0032] See Figures 1 to 7As shown, further, in one embodiment of this utility model, the magnetic snap-fit ​​part 20 includes a boss 21 and a magnet 22. The boss 21 protrudes from the first splicing side 10a, and the magnet 22 is disposed on the boss 21. At least part of the boss 21 can be snapped into the snap-fit ​​groove 30 so that the magnet 22 and the connector 40 are magnetically attracted to each other. It should be noted that the boss 21 in this embodiment can be arc-shaped, square, triangular, etc. Correspondingly, the shape of the snap-fit ​​groove 30 matches the boss 21. The boss 21 can be detachably installed on the display unit 10 by bolts, buckles, etc. In this way, the boss 21 can also be finely adjusted on the display unit 10 by setting a U-shaped groove or other structure. Alternatively, the boss 21 and the display unit 10 can be integrally formed by injection molding, die casting, etc. The magnet 22 can be disposed on the surface of the boss 21, or it can be embedded in the boss 21 under the premise of ensuring magnetic connection with the connector 40. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. By setting the boss 21 as the mounting base of the magnet 22, the boss 21 can withstand the stress of pushing, pulling and sliding parallel to the splicing surface, preventing the display unit 10 from being misaligned and avoiding the phenomenon of the magnet 22 chipping or breaking when simply relying on the magnet 22 for snapping.

[0033] See Figures 1 to 7 As shown, further, in one embodiment of this utility model, the boss 21 has a mounting groove 21a, and the magnet 22 is at least partially accommodated in the mounting groove 21a. It should be noted that in this embodiment, the boss 21 has a mounting groove 21a, and the magnet 22 is embedded in the mounting groove 21a. The mounting groove 21a can extend along the thickness direction of the display unit 10 or along a direction perpendicular to the thickness of the display unit 10. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. Further, in this embodiment, a magnetic base 23 is detachably installed in the mounting groove 21a, and the magnet 22 is installed in the magnetic base 23. It can be understood that if the magnet 22 is directly pasted or pressed into the mounting groove 21a, the boss 21 may be damaged if the magnet 22 is damaged and needs to be replaced. By setting the magnetic base 23 as an intermediate support, the magnetic base 23 can be removed when replacing, thus avoiding the above-mentioned problems. Moreover, the magnet 22 can be interference-fitted with the magnetic base 23 to prevent the magnet 22 from loosening or shifting. In this embodiment, by setting a boss 21 with a mounting groove 21a, the boss 21 provides a unique positioning point when the display units 10 are spliced, ensuring that the display units 10 can be spliced ​​in a consistent relative position each time. At the same time, by embedding the magnet 22 in the mounting groove 21a, when the display unit 10 is impacted or pried, the stress will be concentrated on the boss 21 and borne and dispersed by the boss 21, avoiding the magnet 22 from being directly impacted and falling off or the surface of the magnet 22 from being worn, thus ensuring the stability of the magnetic connection.

[0034] See Figures 1 to 7As shown, further, in one embodiment of this utility model, the end face of the magnet 22 protrudes from the mounting groove 21a, and the connector 40 is disposed at the bottom of the snap-fit ​​groove 30 so that the end face of the connector 40 magnetically engages with the end face of the magnet 22. It should be noted that in this embodiment, the mounting groove 21a extends along the thickness direction of the display unit 10, and the magnet 22 is placed within the mounting groove 21a with its end face protruding from it. That is, the magnetic attraction surface of the magnet 22 is parallel to the display surface 12a. Correspondingly, the connector 40 is disposed at the bottom of the snap-fit ​​groove 30, and its magnetic attraction surface is also parallel to the display surface 12a. It can be understood that when two display units 10 are joined, the direction of the magnetic attraction force generated by the two is perpendicular to the display surface 12a of the display unit 10. Preferably, the connector 40 is an iron sheet, which is locked in the snap-fit ​​groove 30 by countersunk screws, or it can be glued to the snap-fit ​​groove 30. This arrangement maximizes the contact area between the magnet 22 and the iron sheet, increasing the locking strength of the two adjacent display units 10 and improving the reliability of the entire splicing display module 100. Furthermore, the magnetic attraction between the magnet 22 and the iron sheet, perpendicular to the display surface 12a, further ensures the flatness of the spliced ​​display units 10. At the same time, the clearance fit between the boss 21 and the locking groove 30 allows for adjustment of the gap between the display units 10, reducing the seam between two adjacent display units 10.

[0035] See Figures 1 to 7 As shown, in one embodiment of this utility model, the boss 21 is an arc-shaped boss 21, and the locking groove 30 is an arc-shaped groove, with the arc-shaped boss 21 matching the arc-shaped groove. It should be noted that both the boss 21 and the locking groove 30 in this embodiment have a semi-circular structure. The semi-circular arc structure forms a good guiding structure. During splicing, the arc edge of the boss 21 can easily slide into the locking groove 30, and the boss 21 is automatically pulled into the locking groove 30 by magnetic attraction, eliminating the need to align the boss 21 and the locking groove 30 during splicing, reducing assembly difficulty and time. At the same time, the arc-shaped boss 21 and the locking groove 30 can withstand repeated insertion and removal and a certain amount of torque, improving the durability of the display unit 10 and the overall service life of the product.

[0036] See Figures 1 to 7As shown, further, in one embodiment of this utility model, the display unit 10 includes a bottom shell 11 and a display panel 12. The display panel 12 is disposed on the bottom shell 11, and the boss 21 and the snap-fit ​​groove 30 are integrally formed with the bottom shell 11. It should be noted that the display panel 12 in this embodiment includes a PCB board and a plurality of LED beads. The plurality of LED beads are disposed on one side surface of the PCB board to form a display surface 12a. The side of the PCB board away from the LED beads is also provided with electrical components such as a driving circuit, a connection circuit, solder pads, and a controller for controlling the LED beads. The bottom shell 11 is fixed on the side of the PCB board away from the display surface 12a. The bottom shell 11, the boss 21, and the snap-fit ​​groove 30 adopt an integrally formed structure, making the three into a whole, reducing production costs, and avoiding errors that may be caused by manual assembly. At the same time, the integrally formed structure has no assembly gaps, which can effectively prevent dust and moisture from entering the module from the connection point, giving the display unit 10 a certain degree of waterproof capability.

[0037] See Figures 1 to 7 As shown, further, in one embodiment of this utility model, the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 extend along the thickness direction of the display unit 10, but do not extend to the display surface 12a of the display unit 10. It should be noted that in this embodiment, the magnetic snap-fit ​​part 20 extends a certain thickness from the bottom surface of the bottom shell 11 along the thickness direction of the display unit 10 on the first splicing side 10a, but does not extend to the display panel 12. Correspondingly, the snap-fit ​​groove 30 is opened from the bottom surface of the bottom shell 11 along the thickness direction of the display unit 10 on the second splicing side 10b, but does not extend to the display panel 12. That is, the snap-fit ​​groove 30 only penetrates the bottom surface of the bottom shell 11. It can be understood that when the display unit 10 is spliced, the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 engage along their thickness direction to limit the position, so that the position of the display unit 10 is fixed after splicing, further ensuring the flatness of the display unit 10 after splicing. Of course, the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 can also be located between the bottom surface of the bottom shell 11 and the display panel 12, so that the magnetic snap-fit ​​part 20 will not be visible when viewed from the display surface 12a after the display unit 10 is spliced, thus avoiding affecting the display effect. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0038] See Figures 1 to 7As shown, further, in one embodiment of this utility model, the display unit 10 includes a plurality of magnetic snap-fit ​​portions 20 and a plurality of snap-fit ​​slots 30, which are disposed opposite to each other on the first splicing side 10a or the second splicing side 10b. It should be noted that the display unit 10 of this embodiment has a plurality of magnetic snap-fit ​​portions 20 and a plurality of snap-fit ​​slots 30. This can be because the first splicing side 10a has a plurality of magnetic snap-fit ​​portions 20, and the second splicing side 10b has a plurality of corresponding snap-fit ​​slots 30. Alternatively, the first splicing side 10a has a plurality of staggered magnetic snap-fit ​​portions 20 and snap-fit ​​slots 30, and the second splicing side 10b also has a plurality of staggered magnetic snap-fit ​​portions 20 and snap-fit ​​slots 30, with the magnetic snap-fit ​​portions 20 of the first splicing side 10a and the snap-fit ​​slots 30 of the second splicing side 10b arranged symmetrically. This embodiment provides multiple magnetic snap-fit ​​parts 20 and multiple corresponding snap-fit ​​slots 30, enabling adjacent display modules 100 to have multiple snap-fit ​​points during splicing, thereby forming multiple constraint points and increasing the connection strength and stability of the spliced ​​display modules 100. Specifically, this embodiment can adjust the number of magnetic snap-fit ​​parts 20 and snap-fit ​​slots 30 according to the size of the display unit 10 to achieve splicing of adjacent display units 10. This embodiment is not limited to these limitations, and all of the above are within the protection scope of this utility model.

[0039] See Figures 1 to 7 As shown, further, in one embodiment of this utility model, multiple magnetic snap-fit ​​parts 20 are spaced apart along the first splicing side 10a, and multiple snap-fit ​​slots 30 are spaced apart along the second splicing side 10b, with each magnetic snap-fit ​​part 20 corresponding to each snap-fit ​​slot 30. It should be noted that in this embodiment, the first splicing side 10a of the display unit 10 is provided with multiple magnetic snap-fit ​​parts 20 at intervals, and the second splicing side 10b is provided with multiple corresponding snap-fit ​​slots 30 at intervals. This splicing structure allows the magnetic snap-fit ​​parts 20 and snap-fit ​​slots 30 to form multiple splicing points when adjacent display units 10 are spliced, making the stress points relatively dispersed, and the error of each splicing point is independent and will not be transmitted or accumulated to the next splicing point. This can effectively reduce the relative twisting between individual display units 10. Therefore, no matter how large the screen size is spliced, the gap can be kept consistent, and the overall flatness is better. At the same time, each connection point has a corresponding allowance for fine adjustment, making splicing installation more convenient, and the spliced ​​screen structure is more stable.

[0040] This embodiment provides a display screen 1000, including the display module 100 described above. It should be noted that, as... Figure 7As shown, the display screen 1000 in this embodiment also includes a cabinet, which can be a steel structure cabinet or a die-cast cabinet. Several display units 10 are spliced ​​together to form a display module 100, that is, the screen of the display screen 1000. After splicing, they are laid on the cabinet to form a complete display screen 1000. The display module 100 includes at least two display units 10. The display unit 10 has a first splicing side 10a and a second splicing side 10b arranged back to back. The first splicing side 10a is provided with a magnetic snap-fit ​​part 20. The second splicing side 10b is provided with a snap-fit ​​groove 30 that matches the snap-fit ​​part. A connector 40 is provided in the snap-fit ​​groove 30. The magnetic snap-fit ​​part 20 is embedded in the snap-fit ​​groove 30 and magnetically engaged with the connector 40 so that the two display units 10 are fitted together. By setting the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 to magnetically attract each other, adjacent display units 10 can be spliced ​​together. Since the mutual interlocking of the magnetic snap-fit ​​part 20 and the snap-fit ​​groove 30 has a guiding and positioning function, the influence caused by the unevenness of the steel structure itself is eliminated, and the unevenness and gap problems of the display module 100 installed on the steel structure box are solved.

[0041] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
