[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] Please see Figures 1 to 2 An LED display unit 10 provided in this embodiment of the present invention includes a housing 100, a display module 200, a HUB board 300, and a power supply 400. The housing 100 includes a rear cover plate 110 and a surrounding member 120 connected around the rear cover plate 110. The display module 200 is disposed on the surrounding member 120, and the surrounding member 120 is sealed to the back side of the display module 200. The HUB board 300 is disposed inside the rear cover plate 110 and located on the back side of the display module 200. The power supply 400 is disposed inside the rear cover plate 110 and located on the back side of the display module 200, and the power supply 400 is electrically connected to the HUB board 300.

[0044] Understandably, the power supply 400 is located inside the enclosure 100 for direct electrical connection to the HUB. This arrangement eliminates the need for complex circuitry to connect the power supply 400 to the display module 200, thus facilitating the manufacturing of the LED display unit 10. The enclosure 120 of the enclosure 100 is sealed to the back of the display module 200, providing waterproofing for the HUB board 300 and power supply 400 inside the enclosure 100. Furthermore, the LED display unit 10 does not require a separate power supply 400 enclosure for installation, further simplifying the structure of the LED display unit 10, thereby facilitating its manufacturing and reducing production costs.

[0045] In some embodiments, please refer to Figures 1 to 2 The LED display unit 10 also includes a sealing ring 500, which abuts against the enclosure 120 and the display module 200. That is, one side of the sealing ring 500 is sealed and attached to the edge surface of the enclosure 120, and the other side is sealed and attached to the edge area of ​​the back of the display module 200. Thus, the back side of the display module 200 is sealed and connected to the enclosure 120 through the sealing ring 500.

[0046] In some embodiments, please refer to Figures 1 to 3The sealing ring 500 has a first positioning protrusion 520 along its periphery, and the enclosing member 120 has a first positioning groove 121 along its enclosing direction. The first positioning groove 121 is U-shaped, and the first positioning protrusion 520 is embedded in the first positioning groove 121. This arrangement achieves relative positioning between the enclosing member 120 and the sealing ring 500, effectively preventing poor sealing of the display module 200 due to movement of the sealing ring 500. More precisely, the sealing ring 500 can precisely fit the gap between the enclosing member 120 and the display module 200, thereby ensuring a sealed connection between the enclosing member 120 and the display module 200. Alternatively, the first positioning protrusion 520 can be provided on the enclosing member 120, and the first positioning groove 121 can be provided on the sealing ring 500, with the first positioning protrusion 520 embedded in the first positioning groove 121.

[0047] It is understandable that the first positioning protrusion 520 is disposed on the sealing ring 500. The first positioning protrusion 520 can be hidden in the first positioning groove 121 on the enclosure 120. With this arrangement, when the sealing ring 500 is applied between the display module 200 and the enclosure 120, the sealing ring 500 occupies less space in its thickness direction, thereby ensuring the aesthetics of the LED display unit 10.

[0048] In some embodiments, please refer to Figures 1 to 3 The sealing ring 500 has a dovetail structure 510 on its outer edge and / or inner edge, thus providing dovetail portions on both sides. The sealing ring 500 is positioned between the display module 200 and the enclosure 120. One dovetail portion of the dovetail structure 510 fits against the edge of the enclosure 120, and the other dovetail portion fits against the edge area of ​​the display module 200. Therefore, the sealing ring 500 is tightly connected between the display module 200 and the enclosure 120. When external water flows through the sealing ring 500, the water pressure causes the dovetail structure 510 to fit even more tightly against the edge area of ​​the enclosure 120 and the display module 200, ensuring a sealed connection between the display module 200 and the enclosure 120, thereby achieving better waterproof and dustproof effects.

[0049] In some embodiments, please refer to Figures 2 to 4 The inner periphery of the sealing ring 500 is provided with first lugs 523 in sequence, and each first lug 523 is provided with a first positioning post 5231 (see reference). Figure 5 and Figure 6Simultaneously, the inner side of the enclosure 120 is provided with second lugs 123 in sequence, and each second lug 123 is provided with a second positioning hole 610. First positioning pins 5231 are inserted into the first positioning holes 1231. With this arrangement, the enclosure 120 and the sealing ring 500 are positioned relative to each other, and the sealing ring 500 can precisely fit into the gap between the enclosure 120 and the display module 200, thereby ensuring a sealed connection between the enclosure 120 and the display module 200. Alternatively, the first positioning pins 5231 can be provided on the enclosure 120, the first positioning holes 1231 can be provided on the sealing ring 500, and the first positioning protrusions 520 can be embedded in the first positioning holes 1231.

[0050] It is understandable that the first positioning post 5231 is set on the sealing ring 500. The first positioning post 5231 can be hidden in the first positioning hole 1231 on the enclosure 120. With this setting, when the sealing ring 500 is applied between the display module 200 and the enclosure 120, the thickness of the sealing ring 500 is small, thereby ensuring the aesthetics of the LED display unit 10.

[0051] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 The sealing ring 500 has an inner section 530, which is cross-shaped and connected to the four sides of the sealing ring 500. The inner section 530 divides the sealing ring 500 into multiple sealing openings; for example, it divides the sealing ring 500 into four sealing openings, each corresponding to one of the four display modules 200, thus sealing the inner sides of the four display modules 200. The inner side of the housing 100 has a support frame 600 that abuts against the inner section 530. The support frame 600 is cross-shaped and adapts to the inner section 530. In practical applications, the support frame 600 can be fitted snugly against the inner side of the inner section 530, keeping the inner section 530 abutting against the back side of the display module 200, thereby ensuring a tight fit between the sealing ring 500 and the back side of the display module 200. The support frame 600 and the housing 100 can be separate components, or the support frame 600 can be fixed to the housing 100 by screws.

[0052] In some embodiments, please refer to the figure. Figure 2 and Figure 4The intermediate section 530 has a second positioning protrusion 533 along its length, and the support frame 600 has a second positioning groove 620 along its surrounding direction. The second positioning groove 620 is U-shaped, and the second positioning protrusion 533 is embedded in the second positioning groove 620. This arrangement achieves relative positioning between the support frame 600 and the intermediate section 530, thus achieving positioning between them. This arrangement also allows the intermediate section 530 to precisely fit within the gap between the support frame 600 and the display module 200, ensuring a sealed connection between them. Alternatively, the second positioning protrusion 533 can be located on the support frame 600, with the second positioning groove 620 on the intermediate section 530 and the second positioning protrusion 533 embedded within it.

[0053] It is understandable that the second positioning protrusion 533 is set on the middle section 530. The second positioning protrusion 533 can be hidden in the second positioning groove 620 on the support frame 600. With this setting, when the middle section 530 is applied between the display module 200 and the support frame 600, the thickness of the middle section 530 is smaller, thereby ensuring the aesthetics of the LED display unit 10.

[0054] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 The intermediate section 530 is provided with second positioning posts 531 sequentially along its length, and the support frame 600 is provided with second positioning holes 610 sequentially along its length. The second positioning posts 531 are inserted into the second positioning holes 610 one by one. This arrangement achieves relative positioning between the support frame 600 and the intermediate section 530, thus ensuring proper positioning between them. Therefore, the intermediate section 530 can precisely fit within the gap between the support frame 600 and the display module 200, ensuring a sealed connection between them. Alternatively, the second positioning posts 531 can be located on the support frame 600, the second positioning holes 610 on the intermediate section 530, and the second positioning protrusions 533 embedded within the second positioning holes 610.

[0055] Understandably, the second positioning post 531 is set on the middle section 530. The second positioning post 531 can be hidden in the second positioning hole 610 on the support frame 600. With this setting, when the middle section 530 is applied between the display module 200 and the support frame 600, the thickness of the middle section 530 is smaller, thereby ensuring the aesthetics of the LED display unit 10.

[0056] Furthermore, to enhance the sealing between the intermediate section 530 and the display module 200 and the support frame 600, protruding wing-shaped structures 532 are provided on opposite sides of the intermediate section 530 (see reference). Figure 2 and Figure 4 More precisely, the wing-shaped structure 532 is designed in the shape of a dovetail structure 510 and is located on both sides of the middle section 530. One side of the wing-shaped structure 532 of the middle section 530 is fitted to the support frame 600, while the other side is fitted to the edge area of ​​the back of the display module 200. Two sets of wing-shaped structures 532 are provided on each side of the middle section 530 for use by adjacent display modules 200. Thus, the middle section 530 is tightly fitted between the display module 200 and the support frame 600, thereby ensuring a tight, sealed connection between the display module 200 and the support frame 600, preventing dust and rainwater from entering the housing 100 through the space between the support frame 600 and the display module 200.

[0057] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 9 The rear cover plate 110 is provided with a first separation plate 111. The first separation plate 111 is usually located in the corner area of ​​the rear cover plate 110. The first separation plate 111 is thinned around its perimeter, for example, the thickness of the thinned part of the first separation plate 111 is one-tenth of the thickness of the first separation plate 111. If no wire needs to pass through the position corresponding to the first separation plate 111, the operator does not need to separate the corresponding first separation plate 111 from the box 100, thereby ensuring the integrity and sealing of the box 100. Of course, if a wire needs to pass through the position corresponding to the first separation plate 111, the operator can easily separate the corresponding first separation plate 111 from the box 100 to allow the wire connected to the power supply 400 to pass through, due to the thinning of the first separation plate 111 around its perimeter.

[0058] Furthermore, the inner side of the first separating plate 111 is provided with a first protrusion 1111, which is columnar in shape and has a first insertion hole for inserting tools. When it is necessary to separate the first separating plate 111 from the rear cover, the operator can insert a tool into the first insertion hole to easily pry the first separating plate 111, thereby forming a clearance hole on the rear cover for wires to pass through.

[0059] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 10The enclosure 120 is provided with a second separation plate 122, which is usually located in the corner area of ​​the enclosure 120. The second separation plate 122 is thinned around its perimeter; for example, the thickness of the thinned portion of the second separation plate 122 is one-tenth of its original thickness. If no wire needs to pass through the location corresponding to the second separation plate 122, the operator does not need to remove the corresponding second separation plate 122 from the enclosure 100, thus ensuring the integrity and sealing of the enclosure 100. Of course, if a wire needs to pass through the location corresponding to the second separation plate 122, the operator can easily remove the corresponding second separation plate 122 from the enclosure 100 due to the thinning around its perimeter, allowing the wire connected to the power supply 400 to pass through.

[0060] Furthermore, the inner side of the second separating plate 122 is provided with a second protrusion 1221, which is columnar in shape and has a second insertion hole for inserting tools. When it is necessary to separate the second separating plate 122 from the enclosure 120, the operator can insert a tool into the second insertion hole to easily pry the second separating plate 122, thereby forming a clearance hole on the enclosure 120 for the wire to pass through.

[0061] It should be noted that the enclosure 100 may only have the first separation plate 111, or only the second separation plate 122, or both. Specifically, when rear maintenance of the LED display unit 10 is required, workers use tools to separate the first separation plate 111, while the second separation plate 122 remains closed to the enclosure 120, facilitating rear maintenance of the LED display unit 10. When front maintenance of the LED display unit 10 is required, workers use tools to separate the second separation plate 122, while the first separation plate 111 remains closed to the enclosure 120, facilitating front maintenance of the LED display unit 10. Therefore, if the enclosure 100 has both the first separation plate 111 and the second separation plate 122, it facilitates both front and rear maintenance of the LED display unit 10.

[0062] This application also discloses a display device 11, as shown in the reference. Figure 1 and Figure 11 It includes the aforementioned LED display unit 10, and multiple LED display units 10 are spliced ​​together.

[0063] It is understandable that the display device 1 uses the aforementioned LED display unit 10, and the power supply 400 of each LED display unit 10 is located inside the housing 100 to be directly electrically connected to the HUB. This arrangement eliminates the need for complex circuitry to connect the power supply 400 to the display module 200, thereby facilitating the production and manufacturing of the LED display unit 10 and consequently the manufacturing of the display device 1. Furthermore, the LED display unit 10 does not have a separate power supply 400 box for installing the power supply 400, which further simplifies the structure of the LED display unit 10, thereby facilitating the production and manufacturing of the display device 1 and saving on the production cost of the display device 1.

[0064] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
