Moisture-proof and anti-salt spray treatment of LED display

2020-11-04

For the application in coastal projects, the products can be processed from the following aspects:
1. The choice of LED lamp beads: In the humid environment of coastal areas, small LED Lamps are prone to electrode migration, resulting in the so-called "caterpillar" phenomenon. In the project, we will choose a light tube with a larger luminous tube volume as much as possible while ensuring the dot spacing to reduce the "caterpillar phenomenon."
2. Protection of components: For exposed components, in order to reduce the contact with moisture and salt in the air, and to extend the service life of the components as much as possible, the surface of the components on the back of the box can be painted with three-proof paint .
3. Protection of LED lamp beads: LED lamp beads are an important part of the LED display. In order to ensure the service life of the lamp beads in the environment of high salt and high humidity, the surface of the LED lamp beads is coated with nano protective coating. This paint is a colorless, transparent material that forms a nano-protective layer on the surface of electronic components to completely cover the pins of electronic components, effectively preventing electronic product components from wading in water and being corroded by acid and alkali salts. Under the premise of not affecting the LED display effect, the erosion of the LED lamp beads by the external environment is reduced, and the service life of the LED lamp beads is increased.
