[0003] The screen size of the conventional LED display screen has been determined at the beginning of the design, and it cannot be changed after the equipment is formed. When the user needs to increase the size of the screen display area, the display area of the LED display screen cannot be increased; The display screen is too bulky and fragile. When the user needs to rotate the placed LED display screen, it often needs to be manually rotated, which is not only laborious but also easy to break the LED display screen.
