| titleOfInvention | Sealing ring and LED display screen |
| abstract | Provided is a sealing ring, including a ring body, wherein the ring body includes a ring groove, a first convex ring is provided on each of the upper and lower surfaces of the bottom wall of the ring groove, and the first convex ring is a closed ring with the same extension direction as the ring groove. The side wall of the ring groove reduces the impact force of water, pressure between the first convex ring and sealed body is increased, and the sealing performance of the first convex ring is improved. Further provided is An LED display screen, including a module, box, power box and a plurality of sealing rings, wherein a first sealing ring is disposed between the power box and box, a second sealing ring is disposed between the box and module; the two rings have good sealing performance, which improves sealing performance of the LED screen. |
