11 Moisture-proof Tips for Small Pixel Pitch LED Displays

With the popularity of small pixel pitch LED displays, their daily operation and maintenance need to be given more attention, as this not only ensures work efficiency but also extends their lifespan.

LED display screens are electronic devices that are extremely sensitive to moisture and are more prone to damage due to humidity in daily use. Therefore, keeping fine pixel pitch LED screens from humidity is an important part of LED screen maintenance.

Why Should You Keep Small Pixel Pitch LED Displays from Humidity?

Dehumidification and moisture prevention for LED displays refer to preventing water vapor from entering the internal components of the LED screens and preventing the LED screens from operating in a humid environment.

1. Prevent Condensation

The components of LED display screens are mainly encapsulated with plastic materials such as epoxy resin, which are polymer materials with large gaps between molecules. Therefore, gaseous water molecules can penetrate the LED casing and infiltrate the moisture-sensitive components through these gaps. When the indoor humidity level is high, condensation water can form on the LED screens, causing water stains and moisture to penetrate the internal casing, resulting in screen malfunctions. Keeping small pixel-pitch LED displays helps prevent condensation.

2. Maintain Image Quality

Operating LED displays in high-humidity environments can affect the image quality, resulting in pixel blur or distortion, reducing overall clarity and sharpness. By dehumidifying and maintaining the LED display screen, the expected image quality can be maintained, ensuring that viewers can fully appreciate the high-resolution visual effects.

3. Extend Lifespan

Moisture is one of the common causes of small pitch LED screen failures. When halogen-containing water vapor infiltrates the internal components of the LED display, the halogens can undergo electrochemical reactions with the metals inside the device when powered on, causing leakage, short circuits, corrosion, and other damage. Dehumidifying and maintaining the LED screens helps prevent these issues, prolonging the lifespan of the screens and reducing costly repair or replacement expenses.

4. Reduce Downtime

If the small pitch LED display is damaged due to moisture, it may require repairs or replacement, resulting in downtime. This is particularly problematic for businesses that rely on LED displays for advertising, information dissemination, or entertainment. Regular maintenance and dehumidification of the LED screens can minimize the risk of downtime and ensure uninterrupted operation. Over time, this can save costs and achieve a higher return on investment.

Anyway, protecting fine pixel pitch LED displays from humidity is crucial for maintaining image quality, extending display lifespan, reducing downtime, and maximizing return on investment.

11 Tips for Protecting Small Pixel Pitch LED Displays from Humidity

Transportation and Storage of LED Components

1. When transporting and storing LED components, take precautions to prevent water from coming into direct contact with the LED display screen, which may include padding them with objects or isolating them with waterproof materials.
2. The storage environment for LED components is equally important. Invest in a humidity monitor to regularly track the humidity levels in the room. Ideally, humidity should be maintained between 40-60%. The optimal storage environment for fine pixel pitch LED displays is: temperature <30°C, humidity <60% RH. In addition, it is necessary to check daily if the environmental temperature meets the working conditions.
3. During the transportation and storage of LED screens and their components, desiccants can be added to absorb moisture in the air.

Packaging of LED Components

1. Vacuum packaging or sealing of LED modules, HUBs, receiver cards, and other components and placing desiccants inside the packaging.
2. Consider using a professional LED display manufacturer for packaging and installation, as they are experts in this field and can provide you with the perfect solution for small pixel pitch LED displays.

Dehumidification of LED Displays in Use

1. After the installation of the narrow pixel pitch LED display, it should be regularly powered on and used. It is recommended to use the LED screen and its supporting equipment at least twice a week for 2 hours each time.
2. If the LED display is not used for a long time (usually 5-10 days), it should be dehumidified before use. Gradually increasing the brightness and slowly warming up the screen will help remove accumulated moisture inside the display.
3. Consider applying a waterproof coating or sealant on the LED screen to provide additional moisture protection. This can help prevent water stains and extend the lifespan of the LED display. However, be cautious when using disinfectants containing chlorine and bromine directly on the LED display screen, as they may cause corrosion to the screen and LED chips.
4. Regularly clean the LED screens to remove any accumulated dust or debris, which will help prevent moisture buildup and potential damage.

Indoor Dehumidification

1. Achieve physical dehumidification by placing a specific amount of desiccants indoors to absorb moisture from the air.
2. Ensure to open windows for ventilation when the weather is clear to accelerate the evaporation of indoor water vapor, thereby reducing the relative humidity of the indoor environment. Also, make sure that the LED display screen is installed in a well-ventilated area, which will help prevent moisture accumulation in the surrounding environment of the screen.
3. During humid and rainy seasons, air conditioning and dedicated dehumidifiers can be used to dehumidify the LED display and the indoor area, preventing the formation of condensation on the screen.With the maturity and widespread application of high-definition display technology, small pixel pitch LED displays are gradually replacing DLP, LCD splicing, and projectors. They are widely used in commercial display scenarios such as conference rooms, education, shopping malls, and cinemas. To maximize your return on investment and ensure the best display quality, it‘s critical to follow these tips to protect small pixel pitch LED displays from moisture.
