As we all know, LCD screens need to be protected from moisture and humidity, but how to protect some LCD screens used outdoors? In some areas, it is a difficult problem to protect indoor LCD screens from moisture during the rainy season. Today, let's talk about this.

First, let's look at the indoor LCD screen. When installing it, it must be installed in a ventilated place. The windows should be opened frequently for proper ventilation to make the indoor environment relatively stable, which will help the water vapor on the surface of the LCD screen evaporate quickly. However, this cannot be done when the humidity is high during the rainy season. You can also place desiccant indoors or turn on the air conditioner to dehumidify, which are relatively effective methods.

Next, we will look at the protection of outdoor LCD screens, which is also very important. Due to the complex environment, we must not only prevent moisture and humidity, but also do daily protection such as waterproofing. Especially in rainy seasons, a good sealing device can effectively reduce the damage of rain to LCD screens and components. Regularly cleaning the inside and outside of the LCD screen can not only effectively dissipate heat but also reduce water vapor adhesion to extend the service life of the LCD screen.

As time goes by, too much humidity will damage the internal parts of the machine (such as PCB boards, circuits, iron frames, etc.), which requires us to take these issues into consideration during production. The surface of the PCB board is coated with three-yellow paint during manufacturing, which has an anti-corrosion effect; high-quality accessories should be used for circuits and small accessories; the iron frame is most likely to rust, so it must be treated with anti-rust.

Finally, whether it is indoors or outdoors, the most effective method is to use it frequently. Heat will be generated during use, which can effectively evaporate water vapor. Therefore, the humidity of an LCD screen that is frequently used is much lower than that of an LCD screen that is not frequently used.
