[0002] LED digital tubes use light-emitting diodes as light-emitting units. The colors include single red, yellow, blue, green, white, yellow-green and other effects. Monochrome and segmented full-color tubes can be used to illuminate the outlines of buildings, roads, and riverbanks. LED digital tubes can be evenly arranged to form a large display area. They can display patterns and texts, and can play video files in different formats. You can download animations, texts and other files on the computer, or use animation design software to design personalized animations, and play various dynamic color-changing graphic effects.

[0003] LED digital tubes are often needed to display different lights and shadows in store promotions and advertisements. Although the existing LED digital tube technology is easy to use and has a long service life, when the LED digital tube is connected to the wires, the wire interface is exposed. If foreign objects collide with the wire interface or the wires shake, the connection between the wires and the LED digital tube may become unstable, resulting in poor light and shadow display effects.
