Description

Sealing structure and display device having the sealing structure

[0001] This application claims priority to Chinese Patent Application No. 202423279726.1, filed on December 27, 2024, entitled "A Sealing Structure and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, the field of display device technology, for example to a sealing structure and a display device having the sealing structure. Background Technology

[0003] A video wall display consists of multiple interconnected display modules. To minimize the impact of the connection points between adjacent display modules on the overall display effect, the distance between the outermost LEDs of one display module and the outermost LEDs of another display module should be consistent with the distance between any two adjacent LEDs within the same display module. If these distances are inconsistent, especially if the distance between the outermost LEDs of one display module and the outermost LEDs of another display module is large, dark lines will appear at the connection points between adjacent display modules when displaying the image.

[0004] As the pixel density of splicing displays increases (the spacing between two adjacent LEDs becomes smaller), the distance between the outermost LEDs of one display module and the outermost LEDs of another display module also needs to be set smaller. Summary of the Invention

Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0035] In existing splicing displays, the lamp panels of the display modules are embedded in a die-cast base shell, meaning the edge of the die-cast base shell covers the outer edge of the lamp panel. As the pixel density of the display increases, the edge of the die-cast base shell also needs to be made thinner, which poses a great challenge to the base shell material and manufacturing process. The product yield is difficult to maintain and may even drop significantly. Moreover, a sealant needs to be applied between the edge of the base shell and the outer edge of the lamp panel to improve waterproof performance. The application of the sealant not only prevents the spacing between the lamp beads at the outermost edges of two adjacent display modules in the splicing display from being further reduced, but also makes it difficult to quickly disassemble the lamp panel and the base shell for maintenance.

[0036] This application provides a sealing structure and a display device to alleviate the current situation where it is difficult to further reduce the gap between the outer edge of the display module and the LED beads.

[0037] The present application will now be described in further detail with reference to the accompanying drawings.

[0038] The sealing structure of this application is schematically shown in conjunction with Figures 1 to 3. The sealing structure includes a lamp plate 10, a frame 20, and a sealing ring 30. The sealing ring 30 is annular and flexible. The sealing ring 30 can be made of silicone material, which allows the sealing ring 30 to be stretched, compressed, or bent.

[0039] As shown in Figures 2 and 3, the lamp panel 10 is mounted on the frame 20. The sealing ring 30 is connected to the frame 20, and the two can be detachably connected. When the frame 20 needs to be disassembled for repair of the lamp panel 10, the sealing ring 30 can be removed directly, followed by the removal of the frame 20. After repair, it can be reinstalled without needing to apply additional glue to the edges of the frame 20 and the lamp panel 10 after repair. The sealing ring 30 surrounds the lamp panel 10, and its inner wall abuts against the outer edge of the lamp panel 10. The sealing ring 30, located between the lamp panel 10 and the frame 20, improves the waterproof performance between them. In some embodiments, the inner circumference of the sealing ring 30 can be smaller than the circumference of the outer edge of the lamp panel 10. This allows for a certain adhesion between the inner wall surface of the sealing ring 30 and the outer edge of the lamp panel 10, thereby improving the tightness of the connection between the sealing ring 30 and the lamp panel 10. In addition to improving waterproof performance, the sealing ring 30 can also serve as a protective structure for the outer edge of the lamp panel 10. In other words, the outer edge of the lamp panel 10 is transformed from the traditional die-cast bottom shell surrounding protection to the sealing ring 30 surrounding protection in this embodiment. The thickness of the sealing ring 30 can be set to be thinner (thinner than the die-cast bottom shell). The distance between the outer edge of the sealing ring 30 and the outermost lamp bead 121 on the lamp panel 10 can be further reduced to improve the pixel density of the display screen.

[0040] In some embodiments, as shown in FIG3, the sealing ring 30 includes a first sealing member 31 and a second sealing member 32. The first sealing member 31 and the second sealing member 32 are connected and arranged perpendicularly to each other, such that the cross-section of the sealing ring 30 is L-shaped. The inner wall surface of the first sealing member 31 is parallel to the outer wall surface of the lamp panel 10, and the inner wall surface of the first sealing member 31 abuts against the outer wall surface of the lamp panel 10 (i.e., the outer edge of the lamp panel 10). The lamp panel 10 has a back surface 11. One end face of the second sealing member 32 abuts against the back surface 11 of the lamp panel 10, and the other end face of the second sealing member 32 is connected to the frame 20. It can be seen that the first sealing member 31 is configured to connect the lamp panel 10 and provide protection for the outer edge of the lamp panel 10, and the second sealing member 32 is configured to provide a waterproof seal between the lamp panel 10 and the frame 20. In some embodiments, the sealing structure further includes a first connecting component, which includes a first protrusion 33 and a first groove 21 that are detachably fitted together. The first protrusion 33 is disposed on the end face of the second sealing member 32, and the first groove 21 is disposed on the frame 20. The second sealing member 32 is detachably connected to the frame 20 through the first connecting component. Moreover, the first protrusion 33 and the first groove 21 are interference fit, which facilitates assembly and provides a stable connection function.

[0041] To prevent moisture from corroding the lamp panel 10, a potting layer 14 is provided on the lamp panel 10, with the potting layer 14 and the frame 20 located on opposite sides of the lamp panel 10. In some embodiments, a plurality of LED beads 121 are provided on the surface of the lamp panel 10 facing away from the frame 20. The lamp panel 10 is also connected to a face shield 15, which has a plurality of through holes through which the LED beads 121 pass. The face shield 15 can prevent other objects from accidentally impacting the lamp panel 10. In some embodiments, the face shield 15 can also be transparent and light-transmitting, providing protection for the lamp panel 10 while allowing the light emitted by the LED beads 121 on the lamp panel 10 to pass through to the outside.

[0042] In some embodiments, as shown in Figures 2 and 3, the lamp panel 10 has a light-emitting surface 12, on which multiple lamp beads 121 can be disposed. The projected area of ​​the frame 20 on the light-emitting surface 12 is smaller than the projected area of ​​the sealing ring 30 on the light-emitting surface 12. When two adjacent sealing structures are spliced ​​together, their respective sealing rings 30 abut against each other, and the frame 20 will not cause structural interference.

[0043] As shown in Figures 2, 4 and 5, in some embodiments, the sealing structure further includes a second connecting component. The second connecting component includes a second protrusion 34 and a second groove 13 that are detachably fitted together. The second groove 13 is located on the outer edge of the lamp plate 10, and the second protrusion 34 is located on the inner wall surface of the sealing ring 30. The arrangement of the second connecting component makes the connection between the sealing ring 30 and the lamp plate 10 more secure, and the sealing ring 30 and the lamp plate 10 are less likely to loosen.

[0044] In some embodiments, the number of second protrusions 34 and the number of second grooves 13 are the same and both are provided in multiples, with each second protrusion 34 corresponding to one second groove 13.

[0045] As shown in Figure 7, in some embodiments, the cross-section of the lamp panel 10 extends along a curve, that is, the cross-section of the lamp panel 10 can be C-shaped or S-shaped, so as to splice together to form various curved display screens. The sealing ring 30 is made of flexible silicone material, which can change arbitrarily with the shape of the lamp panel 10, making it more versatile.

[0046] This application embodiment also provides a display device, including several of the sealing structures described above. A plurality of LED beads 121 are disposed on the lamp panel 10 for displaying images, and the frame 20 is specifically a bottom shell frame 20 supporting the lamp panel 10.

[0047] In summary, the sealing ring 30 is flexible and can be compressed, stretched, or bent. The sealing ring 30 is connected to the frame 20 and surrounds the lamp panel 10. The inner wall of the sealing ring 30 abuts against the outer edge of the lamp panel 10. The sealing ring 30 not only achieves a waterproof seal between the lamp panel 10 and the frame 20, but also serves as a protection for the outer edge of the lamp panel 10, replacing the traditional die-cast bottom shell or die-cast frame 20 as the protection for the outer edge of the lamp panel 10. The distance between the outer edge of the sealing ring 30 and the outermost lamp bead on the lamp panel 10 can be further reduced to improve the pixel density of the display screen.

[0048] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
