[0036] As shown in the drawings, the sealing structure of the present application is schematically shown, which comprises a lamp panel 10, a frame 20 and a sealing ring 30, the sealing ring 30 is annular and has flexibility, and the sealing ring 30 is preferably made of silica gel material, which makes the sealing ring 30 can be stretched, compressed or bent. Figure 2 And Figure 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 maintenance of the lamp panel 10, the sealing ring 30 can be directly removed, and then the frame 20 can be disassembled, and after maintenance, it can be reinstalled without the need to supplement glue on the edges of the frame 20 and the lamp panel 10 after maintenance. The sealing ring 30 is arranged around the lamp panel 10, and the inner wall surface of the sealing ring 30 abuts against the outer edge of the lamp panel 10. The sealing ring 30 is arranged between the lamp panel 10 and the frame 20, which can improve the waterproof performance between the lamp panel 10 and the frame 20. Of course, the inner circumference of the sealing ring 30 can be smaller than the circumference of the outer edge of the lamp panel 10, so that the inner wall surface of the sealing ring 30 and the outer edge of the lamp panel 10 have a certain fit, thereby improving the connection tightness between the sealing ring 30 and the lamp panel 10. In addition to improving the 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 protected by the traditional die-cast bottom shell, which is changed to the protective sealing ring 30 of the present embodiment. The thickness of the sealing ring 30 can be made thinner (thinner than the die-cast bottom shell), and the distance between the outer edge of the sealing ring 30 and the most edge lamp bead 121 on the lamp panel 10 can be further reduced to improve the pixel density of the display screen.
