[0024] refer to Figure 1 One embodiment of the present invention provides a display device 100 including a frame 10, a plurality of display modules 20 mounted on the frame 10, and a power supply box 30 mounted on the frame 10, etc., the power supply box 30 being used to supply power to the display modules 20. In this embodiment, there are 8 display modules 20, mounted on the frame 10 in a 4-row, 2-column arrangement; however, the present invention is not limited to this specific configuration.

[0025] In this embodiment, the display module 20 is an LED display module, including a substrate and an LED display array mounted on the front side of the substrate. The front side of the display module 20 is the light-emitting surface and needs to face the audience when in use. Figure 1 The back side of the substrate is shown schematically.

[0026] In this embodiment, the frame 10 includes four sequentially connected borders 11, with adjacent borders 11 connected by corner brackets 13. The borders 11 and corner brackets 13 are detachably connected, allowing for the selection of appropriate lengths of borders 11 to form a frame 10 of suitable size as needed.

[0027] In this embodiment, the four frame members form a rectangle, namely the top frame, bottom frame, left frame, and right frame. The frame 10 also includes two vertical beams 15 and six horizontal beams 17. The two vertical beams 15 are arranged in parallel, with each end of each beam connected to the top and bottom frame respectively. One vertical beam 15 is connected to the left frame by three horizontal beams 17, and the other vertical beam 15 is connected to the right frame by three horizontal beams 17. The display module 20 is positioned in the corresponding grids defined by the horizontal beams 17. The power supply box 30 is installed on the two vertical beams 15 to supply power to the display module 20.

[0028] refer to Figure 2 and Figure 3 The power supply box 30 is mounted to the vertical beam 15 via a connecting plate 39. The power supply box 30 is elongated and has a cable 37 at one end for connecting to an external power source, etc.

[0029] In this embodiment, the power supply box 30 includes a box body 31 and a top cover 33, with the top cover 33 mounted to the open end of the box body 31. One side of the top cover 33 is rotatably mounted to one side of the box body 31 via several hinges 35, and the other side of the top cover 33 is equipped with several latches 36 for locking to the other side of the box body 31. The box body 31 and the top cover 33 form a closed space for housing circuit boards and related components.

[0030] refer to Figure 4The power supply box body 31 includes a base plate 31a and a first sidewall 31b extending upward from the edge of the base plate 31a. The outer surface of the base plate 31a has an outwardly extending connecting seat 32, which is integrally formed with the base plate 31a. A connector is disposed within the connecting seat 32 to connect with the display module 20. Preferably, an annular sealing ring is fitted around the outer periphery of the connecting seat 32 to enhance its waterproof connection with the display module 20.

[0031] refer to Figure 5 and Figure 6 The power supply box 30 also includes a first waterproof component 41 and a second waterproof component 43 sandwiched between the box body 31 and the top cover 33. The first waterproof component 41 and the second waterproof component 43 form a double waterproof layer in at least a partial area to strengthen the waterproof connection between the box body 31 and the top cover 33. The first waterproof component 41 and the second waterproof component 43 can be arranged adjacent to each other or at a certain distance.

[0032] In this embodiment, the first waterproof component 41 is sandwiched between the top edge 31d of the first sidewall 31b and the top cover 33, and the second waterproof component 43 is sandwiched between the outer side of the first sidewall 31b and the top cover 33.

[0033] refer to Figures 6 to 9 The first waterproof component 41 is a closed-loop ring. The bottom surface 34 of the top cover 33 is provided with a first receiving groove 33c, and the first waterproof component 41 is received in the first receiving groove 33c. In this embodiment, the first waterproof component 41 is provided with a first groove 42 on the side near the box body 31, and the first groove 42 of the first waterproof component 41 is installed to the top edge 31d of the first side wall 31b, thereby enhancing stability and waterproofness.

[0034] The second waterproof component 43 can also be a closed-loop ring. In an alternative embodiment, the second waterproof component 43 is a non-closed-loop ring, or formed from several discrete waterproof components. Preferably, the second waterproof component 43 has a D-shaped cross-section, including a sealing plane 43a and a sealing arc surface 43b sequentially connected to each other. The sealing plane 43a abuts against the first sidewall 31b of the base 31, and the sealing arc surface 43b abuts against the sidewall 35 of the top cover 33. The first sidewall 31b of the housing 31 is provided with a second receiving groove 31c, and the second waterproof component 43 is received in the second receiving groove 31c. Understandably, in an alternative embodiment, the second receiving groove 31c can be located on the sidewall 35 of the top cover 33.

[0035] Preferably, the second waterproof component 43 is provided with a through hole 44 extending along its length direction, and the diameter direction of the through hole 44 is squeezed by the box body 31 and the top cover 33.
