1. Understand the reasons why the LED display screen's lamp beads are damp
1). High humidity environment:
Imagine that when you are in a humid bathroom or wet outdoors after rain, the air is full of moisture.
Similarly, if the LED display screen is in such a high-humidity environment for a long time, especially when the air temperature drops, the moisture will condense into small water droplets on the surface of the display screen.
If the seal of the display is not good enough, these water droplets may penetrate into the interior and contact components such as lamp beads, causing them to get damp.
2). Insufficient sealing:
When installing or maintaining LED displays, you need to ensure that all gaps are properly sealed. If the seal is aged, damaged, or not tightly fitted during installation, gaps will be left.
These gaps are like small doors that allow external factors such as rain and moisture to easily enter the interior of the display. Once the internal humidity rises, sensitive components such as lamp beads will be affected.
3). Condensation caused by temperature difference:
Imagine that on a cold winter day, you walk from the outside into a warm room, and your glasses may fog up immediately. This is because the temperature difference causes the moisture in the air to condense.
In the same way, when the LED display is in an environment with a large temperature difference between indoors and outdoors, condensation may also form on its surface.
If this condensation is not handled in time, it may penetrate into the interior of the display and damage the lamp beads.
4). Improper maintenance:
Daily maintenance is essential to keep LED displays in good condition. If you use an overly wet cloth or improper methods when cleaning, water stains may be left on the surface of the display. If not cleaned for a long time, these water stains and dust will mix together to form dirt that is difficult to remove, further increasing the risk of moisture on the display.
2. Precautions for moisture on LED display lamp beads
1). Choose an LED display with good moisture-proof performance
1.1). The importance of a high IP protection level:
- IP protection level:
This is an international standard for measuring the dust and water resistance of a product. For example, IP65 means that the product is completely protected from dust, and water spraying from any direction will not cause damage to the interior.
Choosing a display with a high IP protection level is like putting a waterproof coat on your display, protecting it from being affected even on rainy days or in humid environments.
- 특징:
These displays usually use special materials and designs, such as corrosion-resistant metal frames and waterproof rubber rings, as well as well-sealed back panels. Their lamp beads and circuit boards are also specially treated to work stably in humid environments.
1.2). High temperature resistant and anti-oxidation materials:
- High temperature resistant:
The display will generate a certain amount of heat when working. If the material is not resistant to high temperatures, it may deform or age. Choosing high temperature resistant materials can ensure that the display screen can operate stably in high temperature environments and will not be damaged due to excessive temperature.
- Anti-oxidation:
Anti-oxidation materials can resist the erosion of oxygen and other oxidizing substances in the air, preventing the surface of the material from discoloring or losing gloss. This is especially important for display screens that are exposed to outdoor environments for a long time.
1.3). Fine lamp bead design:
- Lamp bead sealing:
Lamp beads are one of the key components of the display screen, and their sealing directly affects the moisture resistance of the display screen. Fine lamp bead design can ensure that each lamp bead is tightly wrapped in waterproof materials to prevent water vapor from penetrating.
- 안정:
In addition to moisture resistance, fine lamp bead design can also improve the stability and life of the lamp beads. They usually have better heat dissipation performance and impact resistance and can work normally in various harsh environments.
2). Optimize the installation environment
2.1). Well-ventilated and dry environment:
- Ventilation:
Good ventilation can help reduce environmental humidity and reduce the accumulation of water vapor. When installing the display screen, make sure there is enough space around for air circulation.
- Dryness:
Avoid installing the display screen in humid or water-prone areas, such as basements, rivers, etc. If the environment itself is relatively humid, you can consider using equipment such as a dehumidifier to reduce humidity.
2.1). Avoid condensation caused by temperature difference:
- Temperature difference control:
Direct air conditioning will cause the surface temperature of the display to drop sharply, thus forming condensation. Therefore, when installing the display, avoid placing it near the air outlet of the air conditioner.
- Insulation measures:
In an environment with a large temperature difference, you can consider installing an insulation layer for the display or using other insulation materials to reduce the impact of the temperature difference. This can prevent the formation of condensation and protect the display from damage.
3). Strengthen sealing treatment
3.1). Application of waterproof glue and sealing strips:
- Waterproof glue:
During the installation process, waterproof glue should be applied to key parts such as the surrounding of the display, the cabinet and the cabinet joint. Waterproof glue can fill the gap and form a waterproof barrier to prevent water vapor from penetrating into the interior of the display.
- Sealing strips:
It is also very important to select high-quality sealing strip materials and install them correctly. These sealing strips should have good elasticity and sealing properties, and be able to adapt to the deformation and movement of the display in different environments.
The hollow tube structure can provide better cushioning and sealing effects, while the low compression set rate and high elongation at break mean that the sealing strip can maintain stable performance in long-term use.
3. Daily maintenance and care of LED display lamp beads
For LED display screens, daily maintenance and care are the keys to ensuring their long-term stable operation and extending their service life. The following are some specific maintenance and care measures:
1.1). Regular dehumidification
- Dehumidification in the rainy season:
In the rainy season, due to the high humidity in the air, water vapor is easy to accumulate around the display screen. Therefore, air conditioners or dehumidifiers should be used regularly to dehumidify the environment around the display screen and keep the environment dry.
- Internal dehumidification:
In addition to the external environment, water vapor may also be generated inside the display screen due to temperature differences, poor sealing, etc. At this time, desiccant can be placed inside the display screen, or the dehumidification function of the display screen (if any) can be turned on to absorb and remove internal moisture.
1.2). Regular cleaning
- Clean dust:
It is very important to regularly clean the dust attached to the inside and outside of the display screen.
Dust not only affects the heat dissipation efficiency of the display screen, but also increases the attachment area of water vapor and accelerates the aging of the display screen.
When cleaning, use a soft cloth to wipe gently, and avoid using chemical solvents and strong detergents to avoid damaging the surface of the display.
- 메모:
During the cleaning process, pay special attention to avoiding water or other liquids splashing directly on the display to avoid short circuits or other damage.
1.3). Avoid long-term non-use
- Light up and dehumidify:
Long-term non-use of the display may cause moisture to accumulate inside it. Therefore, the display should be kept off for as long as possible.
In humid areas, it is recommended to light up the display once a day; in dry areas, it can be lit about three times a week, each time for about two hours. Doing so will help dissipate internal moisture through the display’s own heat.
1.4). Inspection and maintenance
- 정기점검:
Regularly check whether the display’s connecting wires, power cords, radiators and other components are intact, and replace damaged components in time to ensure the normal operation of the display.
- Internal inspection:
In a humid environment, it is also necessary to regularly check whether condensation, frost, etc. occur inside the display. Once these problems are found, measures should be taken immediately to prevent moisture from further damaging the display.
- 전문적인 유지 관리:
In addition to daily inspection and maintenance, professionals should be invited to conduct a comprehensive inspection and maintenance of the display screen regularly. They can use professional equipment and methods to detect and repair potential problems, ensuring that the display screen is always in the best condition.
4. Emergency treatment measures
1). Handling after water ingress or moisture
1.1). Immediately cut off the power supply.
중요성: First and foremost, cut off the power supply of the display screen immediately. This is to prevent short circuits, thereby avoiding further damage and potential safety risks.
Operation: Quickly find the power switch and cut it off to ensure that the display screen is completely powered off.
1.2). Gently wipe the wading area
Tool selection: Use a clean, lint-free, absorbent towel or rag.
Operation method: Gently wipe the wading or damp areas of the screen to absorb most of the moisture on the surface. Avoid excessive force to avoid scratches or damage to the screen.
1.3). Dry the display screen.
Tool selection: Turn on the air conditioner dehumidification mode or use a drying device such as a fan (note that it is not a hot air blower).
Operation method: Set the air conditioner to dehumidification mode and make sure that the air outlet is not blowing directly at the screen. At the same time, a fan is used to blow air on the display screen to accelerate the evaporation of internal water vapor. Pay attention to maintaining an appropriate distance and wind speed to avoid unnecessary damage to the screen.
Note: If the above methods still do not work, you must ask a professional maintenance person to perform maintenance. Be sure to pay attention to electrical safety!
