Led display moisture-proof knowledge


      An LED display screen with a protective cover, including a circuit board and an array of LED lights  welded on the circuit board on the circuit board , including a protective cover on the circuit board The PC protective cover  of the LED lamp ; the PC protective cover  protrudes downwards with horizontal ribs  and vertical ribs to form a grid array, and each grid is equipped with an LED Lights. Provide higher safety protection for the surface of the display screen, make it have higher water resistance, improve the protection level of the display screen, and be used outdoors or in harsh environments. At the same time, it can be walked and stepped on, and has a strong anti-slip ability , It is not easy to slip after being wet.

         Whether it is indoors or outdoors, the most effective way to avoid moisture damage is that the display function is frequently used. The working state of the display itself will generate a certain amount of heat, and some water vapor can evaporate, thereby greatly reducing the possibility of short circuit caused by moisture. Therefore, display screens with much lower relative humidity are not used for display screens that are often used; for LED displays, humidity will affect the normal operation of the circuit board, cause short circuits, and damage the function and life of the display. In this special season, it is necessary to master some moisture-proof knowledge.

      1.Indoor LED display is moisture-proof

      The humidity of the indoor air is lower than that of the outside, and it is much easier to prevent water and dust than outdoor screens. In order to avoid that it is abnormal that the indoor air humidified by the LED display, the following method can be used to reduce the humidity.
One. Moderate ventilation. Moderate ventilation can help the water vapor attached to the display to evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in windless and humid weather, as this will increase indoor humidity.

(1.) Place desiccant in the room. Use physical moisture absorption to reduce the moisture in the air and dry the room so you don't have to worry about the screen getting wet.

(2.) Turn on the air conditioner dehumidifier. If the air-conditioned space is displayed during installation, you can turn on the air-conditioning dehumidifier in humid weather.

      2. Moisture-proof of outdoor led display
      The environment of outdoor LED display is more complicated than that of indoor display. Of course, indoor display can also adopt moisture-proof measures, but outdoor display should not only consider the issue of humidity, but also do daily maintenance work such as waterproof and dustproof. A well-sealed installation helps the display reduce the risk of water ingress, regularly cleans the dust attached to the inside and outside of the display, and also helps the display to dissipate heat and reduce water vapor adhesion.
