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.

[0030] 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 schematically shown. Understandably, the display module 20 generates heat when it is in operation. The display module 20 can transfer heat to the frame 10 by thermal radiation or thermal conduction. Preferably, the display module 20 is thermally connected to the frame 10 so that heat can be transferred to the frame 10 by thermal conduction.

[0031] In this embodiment, the frame 10 includes four sequentially connected outer frame edges 11. Adjacent outer frame edges 11 are connected by corner brackets 13. Both the outer frame edges 11 and the corner brackets 13 are thermally conductive metal parts, thereby transferring heat between them. The outer frame edges 11 and the corner brackets 13 are detachably connected, making it convenient to select an appropriate length of outer frame edge 11 as needed to form a frame 10 of a suitable size.

[0032] In this embodiment, the four outer frame members form a rectangle, namely the upper outer frame, lower outer frame, left outer frame, and right outer 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 the vertical beam 15 connected to the upper and lower outer frame members respectively, forming a thermally conductive connection. One vertical beam 15 is connected to the left outer frame by three horizontal beams 17, and the other vertical beam 15 is connected to the right outer frame by three horizontal beams 17. The vertical beams 15 and horizontal beams 17 are also thermally conductive metal parts, forming thermally conductive connections at their joints. 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.

[0033] refer to Figure 2 After the display device 100 is assembled, the display module 20 covers the front of the frame 10, blocking the frame 10 and the power supply box 30, etc.

[0034] refer to Figure 3 and Figure 4 The frame 10 of the display device 100 is provided with a plurality of connecting portions 18, each connecting portion 18 having a non-circular connecting hole 19. The display module 20 is detachably mounted to the connecting portion 18 via the disassembly structure 50.

The power supply box 30 is elongated and has a cable 37 at one end for connecting to an external power source, etc. The connecting plate 39 is a heat-conducting metal component, which facilitates the conduction of heat from the power supply box 30 to the vertical beam 15.

[0036] 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.

[0037] refer to Figure 7 and Figure 8The power supply box 31 includes a base plate and a first sidewall extending upward from the edge of the base plate. The outer surface of the base plate has an outwardly extending connecting seat 32, which is integrally formed with the base plate 31. 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. The power supply box 30 housing is provided with heat dissipation ridges 33f to accelerate heat dissipation. The heat dissipation ridges 33f are provided at least up to the top cover 33. Understandably, heat dissipation ridges can be provided on both the top cover 33 and the box 31 as needed.

[0038] refer to Figures 7 to 9 The power supply box 30 is detachably mounted to the frame 10 via a connecting plate 39. The connecting plate 39 includes a first connecting portion 46 detachably connected to the power supply box 30 and a second connecting portion 48 detachably connected to the frame 10. The first connecting portion 46 is connected to an end of the power supply box 30, allowing operation from the rear of the frame 10, thereby allowing the power supply box 30 to be installed and removed from the rear of the frame 10. The second connecting portion 48 is connected to the front of the vertical beam 15, allowing operation from the front of the frame 10, thereby allowing the power supply box 30 to be installed and removed from the front of the frame 10. Understandably, if the second connecting portion 48 is connected to the rear of the vertical beam 15, the second connecting portion 48 can be operated from the rear of the frame 10; correspondingly, the first connecting portion 46 can be operated from the front of the frame 10.

[0039] In this embodiment, the first connecting part 46 and the second connecting part 48 form an L-shaped bend. The second connecting part 48 is detachably connected to the front of the frame 10, and the first connecting part 46 is detachably connected to the end of the power supply box 30.

[0040] Preferably, both the first connecting part 46 and the second connecting part 48 are sheet-like, and the connecting plate 39 is formed by bending the sheet material. The power supply box 30 is located between the two vertical beams 15. The second connecting part 48 is detachably connected to the two vertical beams 15 by screws, and the first connecting part 46 is detachably connected to the end of the power supply box 30 by screws.

[0041] refer to Figure 10 and Figure 11In this embodiment, the outer frame 11 is provided with frame ridges 11f. The frame ridges 11f accelerate heat dissipation and also have an anti-slip function, making it easier for users to move the frame 10 or display device 100 using the outer frame 11. The vertical beam 15 can also be provided with vertical beam ridges 15f, which also accelerate heat dissipation. The horizontal beam 17 can also be provided with horizontal beam ridges 17f, which also accelerates heat dissipation. When the outer frame 11, vertical beam 15, and horizontal beam 17 are all provided with corresponding ridges, the heat dissipation effect is optimal. Simultaneously, the friction coefficient of the frame 10 is also increased, facilitating user handling. Understandably, ridges can be provided on one or two of the outer frame 11, vertical beam 15, and horizontal beam 17 as needed. Preferably, the frame ridges 11f extend along the length direction of the outer frame 11; the vertical beam ridges 15f extend along the length direction of the vertical beam 15; and the horizontal beam ridges 17f extend along the length direction of the horizontal beam 17.

[0042] In this embodiment, the border ridge 11f is located on the back of the outer border 11; the vertical beam ridge 15f is located on the back of the vertical beam 15; and the horizontal beam ridge 17f is located on the back of the horizontal beam 17. That is, it is set on the back of the frame 10 away from the display module 20.
