With the rapid development of LED technology, LED displays for indoor close-range viewing are gradually replacing DLP, LCD splicing, and projection products, becoming more and more common. The daily issues and maintenance of products have become increasingly important, not only to ensure the efficiency of the user but also to extend the product’s lifespan.

• Check the display screen environment temperature ≤30°C and humidity ≤60% RH daily to ensure it meets working conditions.
• Use the display screen and supporting equipment at least twice a week for 2 hours each time; if the screen is not used for five consecutive days, perform preheating dehumidification before using it again.

Moisture prevention involves preventing moisture and humidity. The packaging materials of LED displays are mainly epoxy resins and other plastics. Plastics are polymer materials with large gaps between molecules, allowing gaseous water molecules to penetrate the LED product casing. LED products are sensitive to moisture and slowly absorb humidity during use.

Harm of Moisture on LED Devices

When LED devices are exposed to moisture and water vapor infiltrates the devices, halogen-containing water vapor from the air can cause electrochemical reactions with the metals inside the devices when powered on. This can lead to chip short circuits, leakage, or electrode detachment, resulting in abnormal display screen lighting.

LED Device Storage

During transportation and storage of LED devices, use objects to elevate them, and prepare for waterproofing and moisture prevention. Monitoring temperature and humidity during storage is crucial. The optimal storage environment is: temperature <30°C, humidity <60% RH, and desiccants should be added during transportation and storage.

Packaging of Spare Modules/HUB/Receiving Cards

Spare modules, HUBs, receiving cards, etc., should be vacuum-sealed or sealed and treated with desiccants.

Indoor Dehumidification

• Physical dehumidification method: Use a set amount of desiccant indoors to reduce moisture in the air.
• Moderate ventilation: Ensure moderate ventilation when the weather is not humid and there is wind to accelerate water vapor evaporation and reduce indoor relative humidity.
• Air conditioning dehumidification: Use air conditioning for dehumidification in humid weather to reduce moisture absorption.
• Use a dedicated dehumidifier for dehumidification.

Dehumidification of Screen During Use

After installation, the screen should be regularly turned on. If the screen is not used for a long time (generally 5-10 days), perform dehumidification before use. Gradually increase brightness and slowly warm up to remove accumulated moisture inside the screen and dehumidify gradually.

LED Display Usage Precautions – Disinfectant

Exercise caution when using disinfectants containing chlorine, bromine, such as 84 disinfectant, and highly effective disinfectant water, directly spraying them on the LED storage, production, and usage environment.
Common disinfectants include 84 disinfectants, ethanol (alcohol) disinfectants, bromine-containing disinfectant water, chlorine dioxide disinfectant tablets, quaternary ammonium salt disinfectants (e.g., Jieer Mie), etc. These disinfectants can effectively disinfect surfaces of objects like desks and floors. However, improper use of chlorine-containing 84 disinfectants, bromine-containing disinfectants, and chlorine dioxide disinfectant tablets may corrode our LED displays and light bulbs.

Screen Dust Removal

For optimal display performance, it is recommended to use an anti-static soft brush to clean dust from the screen surface monthly.

As technology matures and costs decrease, the application of small-pitch LED displays in commercial display markets such as conference rooms, education, shopping malls, and cinemas will become more common. The daily issues and maintenance of products have become increasingly important, not only to ensure the efficiency of the user but also to extend the product’s lifespan.
