These advertising display racks are usually LED fixed products composed of a single modular LED display or multiple modular LED display screens.

[0003] However, this type of LED fixed products can only play the role of displaying pictures. In order to integrate LED fixed products into the display of goods, merchants will place LED fixed products at the back of the product display rack to set off the goods. Since the product display rack is located in front of the LED fixed products, the product display rack will form a certain obstruction to the screen display content of the LED fixed products. As a result, when viewing the goods from the front, the advertising content display effect on the LED fixed products is poor, resulting in defects in the combination of LED fixed products for physical display and static advertising display, and the product display cannot form a good interactive relationship with the LED display screen.
