For display systems in extreme environments, Sansi has a lot of project experience. Moreover, in the early stage of research and development, each product has undergone operation tests in harsh environments to ensure that the product can maintain a good operating state during actual use.
For applications in coastal projects, the product can be treated from the following aspects:
1. Selection 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 lamp with a larger volume of the light-emitting tube as much as possible to reduce the occurrence of the “caterpillar phenomenon” under the condition of ensuring the point spacing.

As shown in the figure above, the red, green and blue LED light-emitting chips are packaged in the airtight structure shown in the above figure. Under the condition that the volume of the light-emitting chips remains unchanged, the airtight structure, that is, the larger the volume of the light-emitting tube, the greater the distance between the light-emitting chips. The larger it is, the less likely it is that electrode migration will occur. Thereby reducing the “caterpillar” phenomenon.
2. Protection of components: For exposed components, in order to reduce the contact with moisture and salt in the air and prolong the service life of the components as much as possible, you can paint the surface of the components on the back of the box with conformal 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 a high-salt and high-humidity environment, the surface of the LED lamp beads is painted with nano-protective coatings. This coating is a colorless and transparent material. It forms a nano-protective layer on the surface of electronic components, completely covering the pins of electronic components, effectively preventing electronic components from wading in water and being corroded by acid and alkali salts. Under the premise of not affecting the LED display effect, the LED lamp beads are reduced from the erosion of the external environment and the service life of the LED lamp beads is improved.
