[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figures 1 to 2 This invention provides an LED display module for sealing connection with the housing 100 of an LED display device. The LED display module includes a lamp panel 200 and a reinforcing frame 300. The lamp panel 200 is disposed on the housing 100, and the surrounding plate 120 is sealingly connected to the back of the lamp panel 200. The reinforcing frame 300 is connected to the back of the lamp panel 200. A sealing edge area is reserved around the reinforcing frame 300 on the back of the lamp panel 200, and the sealing edge area is used for sealing connection of the LED display module to the housing 100.

[0034] During the assembly process, when assembling the reinforcing frame 300 with the lamp panel 200, the lamp panel 200 is first fixedly attached to a flat plate with a high degree of flatness, ensuring that the display surface of the lamp panel 200 remains flat. This can be achieved by clamping, pressing, or using negative pressure relying on atmospheric pressure to press it onto the surface of the fixture. Then, adhesive is applied to the bonding area (this step can also be done earlier, depending on the curing time). The reinforcing frame 300 is then placed freely on the lamp panel 200 with the bonding area facing down, and the clamping force on the lamp panel 200 is removed after the adhesive has cured.

[0035] Understandably, by setting up the reinforcing frame 300, which is fixedly installed on the back side of the lamp panel 200, the reinforcing frame 300 can be made of high-strength material to ensure the flatness of the lamp panel 200. At the same time, a sealing edge area is reserved around the back of the lamp panel 200 and the reinforcing frame 300. The sealing edge area is used for sealing the connection of the LED display module's housing 100. Therefore, no waterproofing treatment is required between the reinforcing frame 300 and the lamp panel 200. The overall structure of the reinforcing frame 300 is simple and can be flexibly designed, and there is no need to worry that the reinforcing frame 300 will affect the flatness of the lamp panel 200.

[0036] In some embodiments, please refer to Figures 1 to 3The reinforcing frame 300 is a rectangular frame. It can be understood that when the reinforcing frame 300 is installed on the back side of the lamp panel 200, the distance from each position of the reinforcing frame 300 to the edge of the lamp panel 200 is set between 0.5cm and 8cm. In other words, the reinforcing frame 300 is fixedly installed on the edge area around the lamp panel 200. This arrangement effectively increases the strength of the lamp panel 200, thereby ensuring the flatness of the lamp panel 200.

[0037] In some embodiments, please refer to Figures 1 to 3 The reinforcing frame 300 is bonded or welded to the back of the lamp panel 200. This design effectively increases the strength of the lamp panel 200. Simultaneously, this configuration of the reinforcing frame 300 effectively ensures the integrity of the lamp panel 200, thereby guaranteeing its performance and waterproofing. Alternatively, the reinforcing frame 300 can also be fixed to the back of the lamp panel 200 with screws.

[0038] In some embodiments, please refer to Figures 2 to 3 Along the length of the reinforcing frame 300, notches 320 are sequentially provided on the side of the reinforcing frame 300 closest to the lamp panel 200. It is understood that the edge area of ​​the back side of the lamp panel 200 is sealed to the enclosure panel 120 of the housing 100. With this configuration, the reinforcing frame 300 does not require waterproofing, and the notches 320 can be provided. Simultaneously, the notches 320, spaced sequentially along the extension direction of the reinforcing frame 300, reduce the contact area between the reinforcing frame 300 and the back side of the lamp panel 200, and ensure that the reinforcing frame 300 effectively increases the strength of the lamp panel 200, thereby ensuring the flatness of the lamp panel 200.

[0039] This application also discloses an LED display device, including a housing 100 and the aforementioned LED display module, wherein the housing 100 includes a rear cover plate 110 and a surrounding plate 120 connected around the rear cover plate 110; the lamp plate 200 is disposed on the housing 100, and the surrounding plate 120 is sealed to the back of the lamp plate 200.

[0040] It is understandable that the LED display device uses the aforementioned LED display module. The LED display module is fixed to the back side of the lamp panel 200 by the setting of the reinforcing frame 300. The reinforcing frame 300 can be made of high-strength material to ensure the flatness of the lamp panel 200. At the same time, the enclosure 120 of the housing 100 is sealed to the edge area of ​​the back side of the lamp panel 200. No waterproofing treatment is required between the reinforcing frame 300 and the lamp panel 200. The overall structure of the reinforcing frame 300 is simple and can be flexibly designed. There is no need to worry that the reinforcing frame 300 will affect the flatness of the lamp panel 200.

[0041] In some embodiments, please refer to Figures 1 to 2 The LED display device also includes a locking mechanism 400. Multiple locking mechanisms 400 can be provided and distributed at multiple positions on the back side of the lamp panel 200. Each locking mechanism 400 includes a first locking module 410 and a second locking module 420. The first locking module 410 is connected to the housing 100, for example, it is fixedly connected to the rear cover plate 110 of the housing 100. The second locking module 420 is connected to the reinforcing frame 300 and / or the back of the lamp panel 200. The first locking module 410 and the second locking module 420 are locked together, thereby securely mounting the lamp panel 200 onto the housing 100, and thus sealing the edge area of ​​the back side of the housing 100 with the edge area of ​​the lamp panel 200.

[0042] In some embodiments, please refer to Figures 1 to 2 A mounting base 310 is fixedly provided on the back of the lamp panel 200. For example, the mounting base 310 is bonded, welded, or fixed to the back side of the lamp panel 200 by screws. The mounting base 310 is located near the corner of the reinforcing frame 300 and is connected to the corner of the reinforcing frame 300. The second locking module 420 is connected to the mounting base 310.

[0043] Understandably, through the mounting base 310, the second locking module 420 is conveniently installed on the back side of the lamp panel 200; and the mounting base 310 is connected to the reinforcing frame 300, thereby increasing the stability of the mounting base 310, and thus allowing the second locking module 420 to be securely installed on the back side of the lamp panel 200, thereby allowing the lamp panel 200 to be securely installed on the housing 100. The reinforcing frame 300 has a fixing function for the mounting base 310, thereby preventing the mounting base 310 from affecting the flatness of the flat plate when installed on the second locking module 420.

[0044] Furthermore, the mounting base 310 has connecting sleeves 311 on both sides, and the ends of the connecting sleeves 311 are fixedly connected to the back side of the lamp panel 200. For example, the ends of the connecting sleeves 311 are bonded to the back side of the lamp panel 200; at the same time, the back of the lamp panel 200 is provided with a positioning post 210, which passes through the connecting sleeves 311 of the mounting base 310, and the base of the second locking module 420 is provided with a fixing member connected to the positioning post 210. For example, the positioning post 210 is provided with a threaded hole, and the fixing member can be a screw, which is threadedly connected to the threaded hole of the positioning post 210, thereby fixing the base of the second locking module 420 to the mounting base 310.

[0045] Understandably, the positioning post 210 is set on the back of the light panel 200 to position the mounting base 310, thereby positioning the reinforcing frame 300 and ensuring the flatness of the light panel 200. At the same time, the positioning post 210 also facilitates the installation of the second locking module 420 on the mounting base 310, making the assembly of the LED display device more convenient.

[0046] In some embodiments, please refer to Figure 1 The LED display device also includes a sealing ring 600, which abuts against the enclosure 120 and the lamp panel 200. That is, one side of the sealing ring 600 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 lamp panel 200. Thus, the back side of the lamp panel 200 is sealed and connected to the enclosure 120 through the sealing ring 600.

[0047] In some embodiments, please refer to Figures 4 to 6 The LED display device also includes a perimeter 500, which includes an annular perimeter 510 and an annular cover 520. The annular perimeter 510 surrounds the lamp panel 200 and has a sufficiently large height to protrude from the front side of the lamp panel 200. This arrangement allows sealant to be injected into the front side of the lamp panel 200 to form a potting layer that protects the LED light-emitting beads on the front side of the lamp panel 200. The potting layer is located inside the annular perimeter 510.

[0048] Meanwhile, the annular cover 520 covers the edge area of ​​the lamp panel 200 near the housing 100, and the annular cover 520 can be used with the sealing ring 600 (see reference). Figure 1 Sealed connection. Of course, if the sealing ring 600 is not provided, the annular cover 520 is directly sealed to the edge of the enclosure 120. As can be seen from the above, the enclosure 500 not only facilitates the installation of a potting layer on the front side of the lamp panel 200, but also ensures the sealing between the lamp panel 200 and the housing 100.

[0049] Furthermore, the lamp panel 200 is provided with slots 220 around its perimeter, and the annular circumference 510 is provided with protrusions 511 around its inner perimeter. The protrusions 511 are embedded in the slots 220, thereby securing the circumference 500 around its perimeter and facilitating the installation of the circumference 500.
