During this period, the weather in Shenzhen has always been gloomy, with occasional showers of moderate to moderate rain. There are small water droplets hanging on the walls, making people feel that the air is moist. It feels like girls can naturally hydrate without taking care of their skin when going out, which makes people have to admit that the weather in the south really has the potential to drive Aquarius crazy.
The south has a lot of rain and humid weather, which drives people crazy not only by the sentimental Aquarius, but also by electronic products including LED displays. For display screens, moisture can affect the normal operation of the circuit board, cause short circuits, and damage the functionality and lifespan of the display screen. It is necessary to master some moisture-proof knowledge during this special season.
1、 Indoor display screen moisture-proof
Indoor air humidity is lower than outdoor, and it is much easier to waterproof and dust-proof than outdoor screens. To avoid abnormal display on the display screen caused by humid indoor air, the following methods can be used to reduce humidity.
1. Moderate ventilation. Moderate ventilation can help the water vapor attached to the display screen evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in windless and humid weather, as this can increase indoor humidity.
2. Place desiccant indoors. By using physical moisture absorption methods to reduce moisture in the air, the indoor environment becomes dry, so there is no need to worry about the display screen getting damp.
3. Turn on the air conditioning for dehumidification. If air conditioning is installed in the space where the display screen is installed, the air conditioning can be turned on for dehumidification in humid weather.
2、 Outdoor display screen moisture-proof
The outdoor display screen itself is located in a more complex environment than indoors, and of course, indoor screen moisture prevention measures can also be taken. However, outdoor screens not only need to consider moisture issues, but also need to do daily maintenance work such as waterproofing and dust prevention. A good sealed installation can help reduce the risk of water ingress on the display screen, regularly clean the dust adhering to the inside and outside of the display screen, and also help the display screen dissipate heat better and reduce the adhesion of water vapor.
In short, whether indoors or outdoors, the most effective way to avoid moisture damaging the function of the display screen is to use it frequently. The working display screen itself will generate some heat, which can evaporate some water vapor, greatly reducing the possibility of moisture causing short circuits. Therefore, the humidity impact on frequently used displays is much smaller than that on infrequently used displays.
