The LED display panels 21 are equipped with LED arrays on both sides, thus forming an LED display board that can display on both sides, which can meet people's usage needs. In addition, its mounting base 10 is composed of a base 11 and a hanging bracket 12 connected by a detachable hooking method. The base 11 can be fixed at the target position 30, while the hanging bracket 12 is used to install the LED display screen 20. Therefore, it is convenient for users to install or remove the LED display screen 20 at the target position 30, which is beneficial to the installation and maintenance of the LED display board.

[0026] Preferably, the thickness of the transparent plate 23 is 3mm to 6mm, and transparent materials such as tempered glass plates and PC transparent plates, which are available in the commercial market, can be selected. During the lamination process of LED display screen 20, the transparent plate 23 often needs to be cleaned and dried to remove dust and other impurities adhering to it.

[0027] The optical adhesive 22 can be, but is not limited to, existing transparent non-conductive optical adhesives available on the commercial market, such as ethylene-vinyl acetate copolymer (EVA) film and polyvinyl butyral (PVB) film.

[0028] exist Figure 6In the illustrated embodiment, the LED display panel 21 includes a circuit board 210 with conductive lines formed on both sides and two LED arrays 211 respectively soldered to the conductive lines on both sides of the circuit board 210. Figure 7 In the embodiment shown, the LED display panel 21 includes two circuit boards 210 with conductive lines formed on their outer surfaces that are attached to each other, and two LED arrays 211 respectively soldered to the conductive lines of the two circuit boards 210.

[0029] refer to Figures 1 to 4 In the preferred embodiment shown in the attached drawings, the base 11 is designed as a generally rectangular parallelepiped, including a first top plate 110, first side plates 111 extending rearward from each of the two sides of the first top plate 110, a first upper end plate 112 extending rearward from the upper end edge of the first top plate 110, and a first lower end plate 113 extending rearward from the lower end edge of the first top plate 110. At least one hanging post 114 is provided on the outer surface of each of the two first side plates 111. The hanging post 12 is also designed as a generally rectangular parallelepiped, including a second top plate 120 with a length L2 greater than the length L1 of the first top plate 110, and a first upper end plate 112 extending rearward from the upper end edge of the first top plate 110, and a first lower end plate 113 extending rearward from the lower end edge of the first top plate 110. The second side plate 121 extends rearward from both sides of the second top plate 120, the second upper end plate 122 extends rearward from the upper end edge of the second top plate 120, and the second lower end plate 123 extends rearward from the lower end edge of the second top plate 120. Each of the two second side plates 121 has at least one hook groove 124. The hook groove 124 includes a guide portion 1240 recessed rearward from the rear edge of the second side plate 121 and a positioning portion 1241 extending upward from the guide portion 1240. The hook post 114 is correspondingly inserted into the hook groove 124 so that the hook 12 covers the base 11 and realizes the detachable hooking of the two. Preferably, when the hanger 12 is attached to the base 11, the second upper end plate 122 abuts against the first upper end plate 112, and the two second side plates 121 abut against the two first side plates 111. Therefore, the hanging stability of the hanger 12 is improved by limiting the hanger 12 from above and / or from both sides by the base 11. Preferably, the hanging post 114 is a screw that engages with the first side plate 111. Therefore, after the hanger 12 is attached to the base 11, the hanging post 114 can be tightened to lock the hanger 12.

[0030] See Figures 2 to 4 In some embodiments, the base 11 extends outward from the rear edge of its first upper end plate 112 and the rear edge of its first lower end plate 113 respectively to form at least one mounting plate 115. The mounting plate 115 has mounting holes 1150. By means of the mounting plate 115, the base 11 can be fixed at the target position 30 by fasteners such as expansion bolts.

[0031] In the embodiment shown in the accompanying drawings, the LED display screen 20 is fixed to the mounting bracket 12 by at least two clamping members 13, such as Figures 1 to 3 As shown, the mounting bracket 12 is fixed with at least two longitudinally distributed clamping members 13. Each clamping member 13 includes a connecting portion 130 and clamping arms 131 extending rearward from both sides of the connecting portion 130. A clamping position 132 is formed between the two clamping arms 131. The LED display screen 20 extends rearward to form a clamping portion 230, which is inserted into the clamping position 132. The clamping arms 131 and the clamping portion 230 are connected by connectors 133 such as bolts or screws to fix the LED display screen 20 to the clamping member 13. In some embodiments, the second top plate 120 and the connecting portion 130 can be connected by connectors such as bolts or screws to fix the clamping member 13 to the mounting bracket 12.

[0032] See Figure 2 , Figure 3 and Figure 5 In this embodiment, an opening 231 is formed at the transparent plate 23 on one side of the clamping part 230. A mounting frame 24 is provided corresponding to the opening 231, and the driver board 25 of the LED display 20 is disposed in the mounting frame 24, thus making the structure of the LED display 20 more compact. Preferably, sealant is injected into the mounting frame 24 to wrap the driver board 25, thereby protecting the driver board 25 disposed in the mounting frame 24. The electrical connection between the driver board 25 and the LED display panel 21 can be performed using existing technology, and will not be described in detail here. Referring to the accompanying drawings, decorative plates 26 corresponding to the mounting frame 24 are provided on both sides of the clamping part 230 to improve the overall aesthetics of the LED display.

[0033] See Figures 2 to 4 As shown, in some embodiments, a first wire hole 1200 is formed at the second top plate 120 of the bracket 12, a second wire hole 1100 corresponding to the position of the first wire hole 1200 is formed at the first top plate 110 of the base 11, a third wire hole 1101 is formed at the first upper end plate 112 and the first lower end plate 113 of the base 11, and a fourth wire hole 1201 corresponding to the position of the third wire hole 1101 is formed at the second upper end plate 122 and the second lower end plate 123 of the bracket 12. The power cord 27 of the LED display screen 20 is passed through the first wire hole 1200, the second wire hole 1100, the third wire hole 1101, and the fourth wire hole 1201 to connect to the external power supply. By constraining the power cord 27 with the wire holes, the messy wiring of the power cord 27 can be avoided, ensuring the overall aesthetics of the LED display.

[0034] In some embodiments, the driver board 25 integrates a wireless communication module to receive control signals from the LED display screen 20, thereby reducing the wiring of the LED display screen 20 and facilitating the control and maintenance of the LED display by staff.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
