| titleOfInvention | Waterproof LED Display |
| abstract | A waterproof LED display screen includes a PCB board, a mask and a plurality of LED lamp beads, each LED lamp bead is arranged on the PCB board, and the mask is provided with a plurality of accommodating holes, and each accommodating hole corresponds to each LED lamp bead one-to-one. It is connected to the PCB board, and each lamp bead passes through its corresponding accommodating hole. The surface of several LED lamp beads is provided with a transparent wear-resistant hydrophobic coating; the mask is set on the side facing the PCB board and the side facing away from the PCB board. There is an adhesive layer and a superhydrophobic coating, and the adhesive layer is located between the mask and the superhydrophobic coating. The bonding force of the super-hydrophobic coating is improved by the adhesive layer, the bonding strength of the coating is good, and the bonding force between the super-hydrophobic coating and the mask is good, which can play a better waterproof effect. By providing a transparent wear-resistant hydrophobic coating on the surface of the LED lamp beads, the LED lamp beads can have a better waterproof effect, thereby making the LED display screen have a better waterproof effect. |
