[0020] When in use, the LED advertising display screen 13 is installed on the insulating frame 10 and is located inside the advertising frame 1. The tempered glass panel 3 is sealed on the front of the advertising frame 1 by sealant. The closed sealing does not affect the display of the advertising content and improves the waterproof sealing. A heat dissipation backplane frame 9 is installed on the inner wall of the advertising frame 1. The heat dissipation backplane frame 9 is used to absorb the heat in the advertising frame 1, and exchange heat with the outside through evaporation and back heat transmission, thereby improving the stability of the working performance of the LED advertising display screen 13.
