The first fixing member 14 fixes the fixing plate 10 to the power supply box 13 in a lateral direction, and one time of the first fixing member 14 can fix a plurality of fixing plates 10. Preferably, the first fixing member 14 is fixed to the power supply box 13 by screws. The groove 102 is matched with the slot 141, and the locking protrusion 103 is matched with the through hole 142, so that the first fixing member 14 can prevent the fixing plate 10 from loosening.

Preferably, the first fixing member 14 is provided with a plurality of catching grooves 141 and through holes 142 in a length direction thereof so as to allow a plurality of fixing plates 10 to be pressed.

Referring to fig. 3, 4 and 5, a first limiting groove 104 is disposed on a side of the fixing plate 10 away from the lamp bead. The power box 13 is provided with a beam 132 matching the first limiting groove 104. The first limiting groove 104 is clamped on the cross beam 132 to prevent the fixing plate 10 from loosening in the axial direction, and is easy to position during installation.

Referring to fig. 3, 4 and 5, a second limiting groove 133 for fixing the board 10 is disposed on one side of the power box 13 close to the beam 132. The fixing plate 10 is tightly clamped in the second limiting groove 133 to prevent the fixing plate 10 from moving laterally, so that the fixing plate 10 is easily positioned during installation. The fixing plate 10 is disposed on the power supply box 13, and the fixing plate 10 is completely engaged with the second limiting groove 133, so that the fixing plate 10 has better stability.

Preferably, the second limiting groove 133 is formed by a gap between two sheets fixed to the power supply box 13.

Referring to fig. 1, 3 and 6, although the fixing plates 10 are made of hard material, they are connected in multiple sections or have a large length, and they are inevitably inclined, so that a locking plate 15 is further disposed between each fixing plate 10. The locking plate 15 is provided with a plurality of locking grooves 151 for fixing the fixing plate 10. The clamping plate 15 and the power box 13 have a certain distance; preferably, the screens board 15 sets up a plurality ofly along the axial direction of fixed plate 10, and a screens board 15 can be fixed a plurality of fixed plates 10 for positional stability between the fixed plate 10 both ends is better, avoids because the phenomenon of rocking that the length overlength of fixed plate 10 produced.

Preferably, referring to fig. 3, 6 and 7, the inner wall of the locking groove 151 is provided with a locking protrusion 152 for preventing the fixing plate 10 from slipping out.

Wherein, the side of the fixing plate 10 is provided with a clamping groove 105 matched with the clamping protrusion. When screens board 15 fixes a plurality of fixed plates 10 in screens groove 151, the protruding 152 joint of chucking is in chucking groove 105 for a plurality of fixed plates 10 form a whole, prevent that fixed plate 10 from rocking or droing, and can keep fixed interval between the fixed plate 10.

Wherein, still include HUB board, send the card. The power supply, HUB board and transmitter card are located in the power supply box 13.

Preferably, referring to fig. 5, a hanging ring 16 is disposed at an end of the power box 13 far from the fixing plate 10 for hanging the transparent display screen in the air.

Specifically, referring to fig. 1 and 6, the vertically arranged strip-shaped circuit board 11 may be an integrally formed integral strip; or a plurality of the LED display screens may be longitudinally connected to form a long circuit board 11, because signal transmission weakens with increasing distance, the LED display screens with high light transmittance are often higher. Therefore, according to the requirement, the strip-shaped circuit board 11 is preferably formed by longitudinally connecting a plurality of circuit boards. The signal connector 17 (such as a pin header) is longitudinally arranged between the strip-shaped circuit boards 11, so that the display effect of the LED display screen is clearer. The length of each section of circuit board 11 is determined according to the height of the display screen, the relationship between the signal transmission distance and the attenuation, and the like.

Specifically, the fixing plate 10 may be an integral strip; or a plurality of short strips with the same length as the circuit board can be spliced. The adjacent fixing plates 10 are detachably connected by a connecting member, such as a pin, a snap member, a screw, a connecting piece, etc. Preferably, the connecting piece is of a U-shaped cross section and is provided with a plurality of pin holes.

Besides the LED lamp beads, the circuit board 11 also has a printed circuit. The printed circuit is a carrier for electrically connecting electronic components of the LED display screen. The area of a traditional LED display screen circuit board is almost the same as that of the display screen, and the transparent display screen is hollowed out at the blank position of the circuit board so as to increase the light transmittance. However, compared with the light transmittance of the existing transparent LED display screen, the light transmittance of the LED display screen is greatly improved.
