1.How much humidity is the Outdoor LED screen wall safe for?
Humidity refers to the proportion of water contained in the air, expressed as a percentage.
Generally speaking, a humidity of 40-60% is considered a relatively comfortable and healthy indoor humidity range.
A humid environment is considered a situation where the humidity exceeds 70%, and LED screen wall are more susceptible to damage in humid environments than in dry environments.
2.The hazards of LED display panel devices affected by moisture
LED screen wall devices get damp, water vapor penetrates into the device, and water vapor in the air penetrates into the device.
When power is on, the halogen in the water vapor will react electrochemically with the metal in the device.
In severe cases, the chip may be short-circuited, leakage, or lose electrodes, resulting in blind lights and abnormal string lights in the display device.
The weather in autumn and winter is humid and the ambient humidity is high.
If the Outdoor LED display panel has not been used for a long time, if preventive measures are not taken, it will lead to dead lights and string lights after lighting.
3.What are the moisture details of outdoor LED Display panels that are easily overlooked?
3.1. Many countries have long rainy seasons or the installation environment is close to the sea or lake, making moisture unavoidable.
Many customers do not understand the performance and classification of LED Screen wall and think that there is not much difference in heat protection and moisture resistance of all outdoor LED displays.
But sometimes because of this, the purchased Outdoor LED display panel cannot be used for a long time in a humid environment and is damaged.
Therefore, customers should explain the local environment to suppliers when choosing an Outdoor LED displays.
For example, the rainy season is long and needs to be waterproof and moisture-proof. In this way, suppliers can recommend products in a targeted manner and avoid incorrect recommendations due to lack of understanding of the climate in the customer’s country.
However, LEGIDATECH outdoor LED Display products are highly waterproof and moisture-proof and can be used in any environment.
3.2.Choose an Outdoor LED Display Panel that meets the relevant rainproof and waterproof standard IP68
It is rainproof and waterproof. The LED display panel adopts modular design and is made of electronic components.
If it is not rainproof and waterproof, it is easy to cause leakage and short circuit, causing unnecessary losses.
LED displays used in outdoor environments must ensure that the equipment . To meet the relevant rainproof and waterproof standard IP68: the LED module is filled with weatherproof glue and the back is also painted with weatherproof glue to make a waterproof box.
A waterproof rubber ring is used at the connection between the LED module and the LED box.
4.How to prevent moisture after outdoor LED advertising screen is installed?
4.1 If you purchased a led screen with insufficient moisture resistance, we can install moisture-proof equipment when installing the LED display. For example, add waterproof strips to the bottom and sides of the display to prevent water vapor from seeping inside.
In addition, professional waterproof coatings can be used to protect the LED display from moisture and provide additional protection.
4.2 The power supply and control equipment of the LED display must also be moisture-resistant. The power supply and control equipment are usually integrated into the display control box.
We can install a LED humidity sensor in the LED control box and connect it to a fan and dehumidifier to keep the humidity inside the LED control box within a controllable range.
4.3 After the outdoor LED display installation is completed, apply waterproof glue around the LED screen and at the connection between the led cabinet and the led cabinet. Use a box structure for LED installation, and magnetic LED installation is prohibited.
4.4 On the first rainy day or after heavy rain after installation, promptly check whether the interior is damp.
4.5 The ambient humidity is between 10% and 85% RH. The LED display panel should be turned on at least once a day and should work normally for more than 2 hours.
If the ambient humidity is higher than 90% RH, perform dehumidification immediately and ensure normal working for more than 4 hours a day.
4.6 Cleaning and maintenance of LED display panel are also important aspects of their protection. In a humid environment, dust and pollutants tend to adhere to the surface of the led display panel, affecting its heat dissipation effect.
Therefore, regular cleaning of the Outdoor LED display panel is necessary. When cleaning, use a clean cloth and avoid using scratching tools to avoid scratching the LED display surface.
4.7 Check the Outdoor LED wall display panel connectors and circuit boards regularly for corrosion. If corrosion is found, damaged parts must be replaced promptly to avoid further damage.
4.8 The Outdoor LED display cannot be turned off for a long time.
In a high-humidity environment, if the LED screen is not used frequently, the preheating lighting method is compulsory.
LED screen preheat guidance:
Step 1: Preheat at 30%-50% brightness for 4-12 Hours
Step 2: Adjust the brightness to normal brightness (80%- 100%) for 12Hours , the heat from the LED Screen will eliminate the moisture , so that no abnormalities occur during use.
4.9 You should pay attention to the correct switch sequence. First turn on the control computer so that it can operate normally, and then turn on the large LED display panel.
Shut down: Turn off the LED display panel first, then turn off the computer.
Finally, check regularly. After the LED display has been installed for a long time, you should always check whether the circuit is damaged. If there is any damage, repair or replace it in time.
5. Storage requirements of Outdoor LED Screen
5.1 According to the environmental conditions of the Outdoor LED wall display body and control part, avoid insect bites and place anti-rodent poison if necessary.
5.2 Keep the flight cases and packaging boxes dry, place desiccant and dehumidification media, and dry the packaging materials that have entered the water vapor in time to avoid contact with water.
5.3 The warehouse where the screen is stored must be dry and have an industrial dehumidifier placed on a high ground.
5.4 After the wet weather, the stored LED display will light up for testing.
5.5 Outdoor LED Screen is waterproof which doesn’t mean it can be stored outside , when the LED Screen is not on , the heat and humidity can easily steam and damage the components .
If necessary, you can seek technical support from the manufacturer LEGIDATECH.
