Description

Technical Field

[0001] The utility model relates to the field of flexible screens, in particular to a magic carpet screen with a flexible transfer soft board. Background Art

[0002] At present, the widespread use of LED screens makes them irreplaceable in the display field, especially in the fields of advertising, stage, building facades, etc. LED screens have been widely used due to their advantages such as bright colors, high brightness and low energy consumption. However, most of the existing magic carpet screens with flexible adapter boards use the traditional wire connection method, that is, each LED lamp bead or light strip is connected to the power supply and control device by manual welding. This manual wire welding method is not only time-consuming and labor-intensive, but also prone to problems such as loose welding and poor contact, which makes maintenance more difficult and reduces the service life of the screen. At the same time, due to the wire welding connection method, the flexibility of the entire screen cloth is poor, and complex bending and folding cannot be achieved, which limits its application scenarios.

[0003] Existing Magic Carpet screens with flexible adapter boards typically require significant time and manual labor to repair. Wire bonding can take hours, and the strength of solder joints cannot be guaranteed. These joints are easily affected by the external environment, leading to poor contact and desoldering. Furthermore, the traditional rigid PCB structure limits the screen's flexibility and foldability, making it difficult to meet the demands of applications requiring high flexibility and portability. Utility Model Content

[0004] To address these issues, the present invention provides a magic carpet screen with a flexible transfer board. By replacing traditional manual wire soldering with a flexible FPC board, the product not only enables automated soldering, significantly improving production efficiency, but also provides stronger solder joints and faster and more convenient maintenance. Furthermore, the flexible FPC board exhibits excellent foldability and flexibility, adapting to complex bending requirements, greatly expanding the application scenarios of the magic carpet screen with a flexible transfer board.

[0007] One or more flexible light strips, one end of each light strip is automatically welded to the light strip welding position by an external welding machine;

[0008] A fabric layer is wrapped around the flexible FPC board and the flexible light strips, and the light beads on the flexible light strips are lit at corresponding positions on the fabric layer;

[0009] A power supply is used to supply power to the flexible light strip and the flexible FPC board.

[0010] As a preferred technical solution, the power source is a battery, and the flexible light strip and the flexible FPC board are powered by the battery.

[0011] As a preferred technical solution, a controller is also included, which is electrically connected to one of the flexible FPC boards and connected to a power supply, and the switching and working mode of each flexible light strip are controlled by the controller.

[0012] As a preferred technical solution, a waterproof layer is provided on the outside of the power supply and the controller, and the waterproof layer is connected to the fabric layer.
