With the widespread application of LED displays in society, especially in outdoor environments, it has become particularly important to address the challenges brought by humid and rainy weather. Here are detailed strategies for waterproofing and moisture resistance of outdoor LED displays during rainy seasons:

1、 Waterproof and moisture-proof measures during the production and manufacturing stage

Anti corrosion treatment of PCB board:
When making PCB boards for LED display screens, anti-corrosion materials should be used and protective layers such as three proof paint should be applied on their surfaces to improve their corrosion resistance.
Selection of high-quality accessories:
High quality and waterproof accessories should be selected for the power supply and power cord to ensure normal operation in humid environments.
Waterproof enclosure and sealing:
Choose a waterproof box with good sealing to ensure that the box meets the IP65 waterproof rating. This means that the box can prevent dust from entering and withstand the jet water flow in any direction without any harmful effects.
Welding and frame protection:
The welding area is the most susceptible to corrosion and should be protected with special protective materials or processes.
The frame part is prone to rusting and should be treated with rust prevention or corrosion-resistant materials such as stainless steel.

2、 Waterproof and moisture-proof measures during on-site installation and construction

Structure and sealing design:
In terms of structural design, waterproofing and drainage functions should be comprehensively considered to ensure that there is no water accumulation inside the display screen.
Use sealing strip materials with hollow bubble tube structure, low compression permanent deformation rate, and high elongation at break to improve the sealing effect.
Selection and installation of sealing strips:
Design appropriate contact surfaces and contact forces based on the characteristics of the sealing strip material, so that the sealing strip can be tightly compressed together to form a dense sealing layer.
Key protection:
During the installation process, key protection measures should be taken for installation gaps, waterproof grooves, and other locations to ensure that there is no accumulated water inside the display screen.

3、 Waterproof and moisture-proof precautions in daily use

Regular use and lighting:
Outdoor LED display screens need to be used frequently because the screens in working condition can generate heat, which helps evaporate water vapor and reduce the risk of short circuits caused by humidity.
During the rainy season, it is recommended to use the display screen at least once a week and light it up for at least 2 hours per month.
Regular cleaning and maintenance:
Regularly cleaning the dust adhering to the inside and outside of the display screen helps to better dissipate heat and reduce the adhesion of water vapor.

Regularly check the sealing and waterproof performance of the display screen to ensure that there is no damage or aging.

In summary, through a series of waterproof and moisture-proof measures in production, on-site installation and construction, as well as daily use, the service life of outdoor LED displays can be effectively extended, and their normal operation can be ensured even in humid and rainy weather.
