The display screen main body is composed of an LED panel 1, a protective surface layer 2, and a curved glass surface layer 3. The installation frame main body includes two upper and lower frame side plates 10 and a support sleeve plate 11 arranged in an arc shape;

[0039] It should be noted that: the installation frame main body itself is arranged in an arc shape, and the curved glass surface layer 3 is also arranged in a matching curved shape. The LED panel 1 and the protective surface layer 2 are linear when not being shaped, which is convenient for processing internal components.

[0040] The LED panel 1 is composed of an insulating bonding layer 101 and a plurality of LED array layers 102 uniformly arranged on the insulating bonding layer 101. The LED array layer 102 is densely provided with light-emitting diode display units;

[0041] Among them, the light-emitting diode display units distributed on the LED array layer 102 have their pins connected to the metal inside the wiring holes 6, so as to achieve a combined type with the wiring assembly strip 4 and enable an effective connection with the wiring contact member 8;

[0042] Furthermore, the LED array layer 102 is composed of LED strip plates arranged in a trapezoidal long strip and densely arranged. Both the upper and lower ends of the LED strip plates are provided with positioning holes 5 in a semicircular shape in pairs. The bottom of the positioning holes 5 is provided with wiring holes 6 connected to the LED strip plates.

[0043] The advantage of the above further measure is that it can achieve an effective current connection of the LED lights in the LED array layer 102 while completing the assembly.

[0044] The protective surface layer 2 is composed of a rear hardening layer 201 and a fitting and assembly layer 202. One side of the fitting and assembly layer 202 is provided with an assembly opening adapted to the LED surface layer. Both sides of the fitting and assembly layer 202 are provided with wiring assembly strips 4 connected to the LED surface layer;

[0046] The rear hardening layer 201 is composed of an outer frame body and an internal resin layer. A liquid injection port 203 penetrating the side wall is provided at the top of the outer frame body. The internal resin layer is formed by injecting liquid from the liquid injection port 203, and it is in an arc shape after solidification. This enables the internal resin layer to be in an arc shape itself after solidification, so as to ensure that the LED panel 1 and the protective surface layer 2 are in a curved state and meet the angle requirements of the curved LED display screen;

[0053] S4. Pour resin: Inject the liquid resin solution from the liquid injection port 203 provided on the outer frame into the outer frame, and gradually wait for the liquid resin to solidify to form a curved built-in resin layer.

[0054] S5. Preliminary assembly: After the built-in resin layer solidifies, take out the LED panel 1 and the protective layer 2 from the shaping device and place them into the curved glass surface layer 3 to form the display screen main body in combination.

[0055] S6. Assembly combination: Install the two frame side plates 10 at the top and bottom. After the frame side plates 10 are installed, wrap and install the support sleeve plates 11 at both ends on the other two side plates of the display screen main body to complete the installation of the installation frame main body and the display screen main body.

[0056] Based on the above: When combining the wiring assembly strip 4 with the LED panel 1 in S2, it is necessary to satisfy the corresponding installation of the positioning holes 5 provided on the LED strip plates and the assembly positioning sleeves 7. In S6, the support sleeve plates 11 squeeze and clamp the frame side plates 10 between the display screen main boards, and firmly connect the support sleeve plates 11 and the frame side plates 10 by adhesion. During the entire assembly process, there is no need to use screws and equipment, which can significantly reduce the processing cost, reduce the process steps, and achieve the effect of optimizing the processing technology.
