[0055] (III) Beneficial effects

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

[0057] A thin steel sheet is used to hold two adjacent display units. After unfolding, the gap in front of the display unit is very small, and the spacing between the edge lamp beads of 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 connection tape is a high-strength non-woven fabric. After being fixed with screws, the two display units are directly tightened when unfolded. When used in combination with thin steel sheets, there is basically no gap between adjacent LED light panels, achieving a seamless splicing effect. The center of the longitudinal connection tape is the curling center. The transverse tape plays a role in ensuring the overall flatness. When the transverse tape is replaced with a hinge, the same effect can be achieved. The power supply and signal lines are opened on both sides of the display unit to facilitate the series connection of the display units. The display unit has a built-in detachable receiving card, and multiple longitudinal connection boards connect the longitudinal display units. Multiple display units in series can be curled into a cylinder after multiple circles, which is convenient for transportation and unfolding. When loaded into the air box, the power supply and sending card are set in the air box, and the docking port is set outside the air box to provide power and signal to the LED curled carpet screen display unit. The LED light board is a COB light board or a surface mount light board. The surface of the surface mount light board is encapsulated with GOB process glue filling and can be stepped on. The rear of the profile unit is provided with multiple contact surfaces for contacting the ground, which will not be deformed when stepped on. Due to the curling design, the carpet screen can bend with the ground when the ground is uneven. The carpet screen display unit is ultra-thin and ultra-light overall. The carpet screen is thin and easy to curl up. Each carpet screen display unit is connected by adjacent longitudinal connecting cloth belts. The longitudinal connecting cloth belts or hinges are arranged at the position of the stepped installation structure, located in the middle of the thickness of the display unit, and the stepped shape will not be blocked when curling backwards. The curling angle of two adjacent display units is large. BRIEF DESCRIPTION OF THE DRAWINGS
