How Should Coastal Countries In Southeast Asia Maintain And Protect LED Displays Screen?


In March, Bibiled began to visit customers in Southeast Asia to discuss LED display screen projects. Since Southeast Asia has a tropical rainforest climate, facing hot and humid seasons of the year, many customers’ questions about protecting and maintaining LED display screens are very important.

As a manufacturer producing LED displays for 7 years, you only need to take the following 4 measures to protect the LED display screen and teach you how to deal with water ingress in the LED display screen; read below, and let’s learn together!

The LED display screen can be installed indoors or outdoors. Indoor LED displays are generally less affected by the environment, while outdoor LED displays are more affected. Therefore, professional LED manufacturers will design outdoor LED displays with waterproof, anti-corrosion, dust-proof, shock-proof, and other functions. However, special protection is still required in bad weather, such as heavy rain and strong wind, especially during the long rainy season.

1.4 protective measures to reduce the damage to your LED display by 80%

  • Take waterproof measures

The LED display screen is vulnerable to heavy rainwater during the rainy season. Once the rainwater seeps into the device, the LED display screen will have problems such as equipment damage and unclear display.

Choose a good-quality outdoor LED display, which will be even better in a waterproof system design.

Adding a waterproof edge or cover around the display screen is necessary during installation. At the same time, a drainage system should also be prepared around the equipment to remove rainwater in time.

  • Take precautions against the wind

In the coastal areas, in addition to the relatively heavy rainfall, there will also be strong winds or typhoons, which will have a certain impact on the LED display.

When installing, be sure to fix the position of the LED display and choose strong nails and bolts to ensure that the seal will not blow down the device.

  • Take lightning protection measures

If the equipment needs to continue to work in thunderstorm weather, professional LED display manufacturers will install lightning protectors and ground wires to protect the equipment from lightning strikes.

If the weather is terrible, it is recommended to turn off the LED display and unplug all the power lines and signal lines.

  • Take dust prevention measures

In addition to the rainy season, Southeast Asia also has a dry season. During the dry season, there will be a lot of dust and impurities in the air, especially in prosperous or industrial areas, which will affect the display effect of the LED display.regularly clean the LED display; for detailed operations, click to learn : Only 4 steps to clean the LED electronic display

2. Oops! What should I do if the LED display screen is flooded?

If you find that the LED display screen has entered the water, start to take the following measures:

  • Cut off the power

The first thing to do is to cut off the power immediately. This is to ensure your safety. The human body is a good conductive medium. It is also an important and basic remedy. Cutting off the power can avoid short circuits and other electrical failures.

  • Remove the LED display

Pour out the water from the inside of the LED display; this step needs to be cleaned very patiently and carefully.

  • Dry screen

There are 3 ways to dry the LED screen:

-dry naturally

Put the LED display in a dry and ventilated place and dry it slowly. This method is only suitable for small areas and not serious cases.

-use desiccant

If the air humidity is relatively high, you can put desiccant around the display; it can not only absorb the moisture in the air to keep the air dry.

-use hair dryers

If you want to dry the display screen quickly, dry the led screen’s surface, but not too close to avoid damage to the circuit board and lamp beads, you can try electric fans, hair dryers, vacuum cleaners, and blowers.

You can use the above three methods according to your actual situation, and they can be used together without contradiction. Our principle is to dry the LED display body completely faster.

-clean circuit board

In this case, you’d better ask a professional to clean it under the guidance of a professional. Although the circuit board is damp, you can use alcohol to wipe it, but if it is not handled correctly, some components on the circuit board will be damaged.

The aging steps of the led screen body after drying:

  • Adjust the brightness (full white) to 10%, power it on, and age for 8-12 hours.
  • Adjust the brightness (full white) to 30%, and power on and age for 12 hours.
  • Adjust the brightness (full white) to 60%, power it on, and age for 12-24 hours.
  • Adjust the brightness (full white) to 80%, power it on, and age for 12-24 hours.
  • Adjust the brightness (full white) to 100%, power it on, and age for 8-12 hours.

-ask professional maintenance personnel to check

Suppose none of the above methods can solve the problem. In that case, it is recommended that you seek the help of professional maintenance personnel so that they can better diagnose the problem and take corrective measures; check whether your LED display is within the maintenance warranty period.


The above are the basic maintenance and protection methods for LED displays. If you do not have any experience in electronic technology, if the LED display has water ingress problems, it is most appropriate to cut off the power while ensuring your safety and then contact professionals to deal with it immediately.
