[0055] (3) Beneficial effects

[0056] The beneficial effects of the present invention are:

[0057] A thin steel sheet is used to hold two adjacent display units together. After unfolding, the gap between the front of the display units is very small, and the spacing between the lamp beads at the edges of the two adjacent display units is consistent, which is suitable for carpet screens with small spacing. Each display unit can be disassembled independently for easy maintenance or replacement. The thin steel sheet is set on the back of the light board and is integrally formed with the back light board. The steel sheet is pressed between the fiberglass boards. The thickness of the steel sheet is 0.2-0.3mm and can be bent multiple times. The studs that fix the light board are pressed into the steel sheet, and the steel sheet cannot be pulled out, which is more secure. Multiple protrusions are provided on one side of the thin steel sheet, which are inserted into the grooves on the back of the other side of the adjacent light board. The protrusions and grooves can be circular or inverted trapezoidal.

[0058] The longitudinal connecting tape is made of high-strength non-woven fabric. After screwing, the two display units are directly tensioned when unfolded. When combined with thin steel sheets, adjacent LED panels are virtually gap-free, achieving a seamless connection. The center of the longitudinal connecting tape serves as the curling center. The transverse tape ensures overall flatness, and the same effect can be achieved when the transverse tape is replaced with a hinge. Power and signal routing is provided on both sides of the display unit, facilitating serial connection of the units. Each unit has a built-in removable receiver card, and multiple longitudinal connecting plates connect the vertical display units. Multiple serially connected display units can be rolled into a cylindrical shape for easy transport and deployment. When installed in an airbox, the power supply and transmitter card are located inside the box, and docking ports are provided on the outside of the box to provide power and signal to the LED curling carpet display units. The LED panels are either COB or surface-mount panels. The surface of the surface-mount panels is encapsulated using a GOB process and is steppable. The rear of the profile unit features multiple ground-contact surfaces, ensuring it remains stable when stepped on. Its curved design allows it to bend with the ground when the floor is uneven. The carpet screen display unit is ultra-thin and lightweight, offering a thin thickness and easy roll-up. Each carpet screen display unit is connected by adjacent longitudinal connecting strips, which are positioned or hinged within the stepped mounting structure, midway through the thickness of the display unit. This allows the stepped shape to be rolled back without obstructing the display unit, allowing for a wide roll-up angle between adjacent display units. BRIEF DESCRIPTION OF THE DRAWINGS
