[0020] Preferably, the thickness of the transparent plate 23 is 3mm to 6mm, and the transparent plate material can be selected from conventional commercially available tempered glass plates, PC transparent plates, etc., but is not limited to these. When manufacturing the LED display screen 20 by laminating, the transparent panel 23 often needs to be cleaned and dried to remove foreign matter such as attached dust.

[0021] The optical adhesive 22 can be selected from conventional commercially available transparent non-conductive optical adhesives such as ethylene-vinyl acetate copolymer (EVA) adhesive film, polyvinyl butyral (PVB) adhesive film, but is not limited to these.

[0022] 6, the LED display panel 21 includes a circuit board 210 having conductive circuits formed on both sides thereof, and two LED arrays 211 welded to the conductive circuits on both sides of the circuit board 210. On the other hand, in the embodiment shown in FIG. 7, the LED display panel 21 includes two circuit boards 210 having conductive circuits formed on their outer surfaces that are bonded together, and two LED arrays 211 welded to the conductive circuits of the two circuit boards 210.

[0023] Referring to Figures 1 to 4, in the preferred embodiment shown in the drawings, the base 11 is designed to be approximately rectangular and includes a first top plate 110, a first side plate 111 extending rearward from each of the two opposite edges of the first top plate 110, a first upper end plate 112 extending rearward from the upper edge of the first top plate 110, and a first lower end plate 113 extending rearward from the lower edge of the first top plate 110, and at least one hanging post 114 is provided on each of the outer surfaces of the two first side plates 111. The seat 12 is designed to be approximately rectangular and includes a second top plate 120 longer than the length L1 of the first top plate 110, second side plates 121 extending rearward from both side edges of the second top plate 120, a second upper end plate 122 extending rearward from the upper edge of the second top plate 120, and a second lower end plate 123 extending rearward from the lower edge of the second top plate 120, and at least one hooking groove 124 is formed in each of the two second side plates 121. The hooking groove 124 includes a guide portion 1240 recessed rearward from the rear edge of the second side plate 121, and a positioning portion 1241 formed by extending upward from the guide portion 1240. By arranging the latch posts 114 in correspondence with the latch grooves 124, the latch seat 12 is placed over the base 11 to achieve detachable latching of the two.

Thus, the base 11 restricts the latch seat 12 from above and / or both sides, improving the latching stability of the latch seat 12. Preferably, the latch posts 114 are screws screwed into the first side plates 111. Thus, when the latch seat 12 is latched to the base 11, the latch seat 12 can be locked by screwing the latch posts 114.

[0024] 2 to 4, in some embodiments, at least one mounting plate 115 is formed extending outward from the rear edge of the first upper end plate 112 and the rear edge of the first lower end plate 113 of the base 11, and a mounting hole 1150 is formed in the mounting plate 115. By installing the mounting plate 115, the base 11 can be fixed to the target position 30 with a fastener such as an expansion bottle.

[0025] In the embodiment shown in the drawings, the LED display screen 20 is fixed to the hanging base 12 by at least two clamping devices 13. As shown in FIGS. 1 to 3 , at least two clamping devices 13 are fixed to the hanging base 12 and are distributed in the longitudinal direction. The clamping device 13 includes a connecting portion 130 and clamping arms 131 extending rearward from both sides of the connecting portion 130, forming a clamping position 132 between the two clamping arms 131. The LED display screen 20 extends rearward to form a clamping portion 230. The clamping portion 230 is disposed at the clamping position 132, and the clamping arms 131 and the clamping portion 230 are connected using connectors 133 such as bolts and screws, thereby fixing the LED display screen 20 to the clamping device 13.
