This is due to their adverse effects on the screen. This is why protecting the LED display or Screen from water is crucial to increase its durability. However, the big questions are, “How do you protect LED displays from Humidity?” and “How to keep display boards from blowing over moisture issues?”

Keep reading to find out; this article will answer all your questions about indoor and outdoor LED display protection. However, before we dive into the different ways to protect LED displays from humidity, Let’s find out what LED displays are all about. Let’s proceed!

What are LED Displays?

LED display, also known as LED screen, is a screen display technology that uses Light-Emiting Diodes (LED) panels as its light source.  It comprises green, blue, and red LEDs mounted in a fixed pattern. These diodes collectively form an image on the Display by varying the brightness of each LED.

These displays are made of Pixels, making it possible to display images, texts, characters, and videos depending on the screen type. These pixels can be bicolor (consisting of two types of colors), Monochromatic (single color), and Polychromatic LEDs. 

Many small and large electronic devices currently use LED displays as a screen and a medium of interaction between the user and the device. LED displays are one of the main screen displays being used commercially today. 

This is because of its efficiency and low energy consumption, which is majorly needed by chargeable and handheld devices such as tablets and mobile devices. Aside from its efficiency and low energy consumption, it produces greater light intensity and more brilliance than its other alternatives. 

These LED screens are often waterproof and most suitable for indoor and outdoor use. They are used in many applicable instances, such as billboards, theatres, conference rooms, shows, tall buildings, and events, to mention but a few.

The world of display technology was brought to life in 1962 thanks to the brilliance of Nick Holonyak’s invention of the first practical LED. This invention led to the first practical LED display (HP Model 5082-7000 numeric indicator) in 1968 by Gerald P. Pighini and Howard C. Borden at Hewlett Packard.

In 1969, they introduced what is known as the first intelligent LED display and the first LED device to utilize integrated circuit technology, replacing the Nixie tube. This introduction thus became the basis for the development of later LED displays. Today, there are many LED displays available. 

Hence, extra care and attention should be taken in its maintenance to avoid contact with moisture, which can damage it or reduce its lifespan or durability. How can moisture damage an LED display? Well, Let’s find out!

How Does Moisture Destroy Your LED Display?

Moisture refers to a small amount of water and other liquids capable of making something wet or moist. Moisture and electronics are like two worlds apart that can never meet or join. This is true even for LED displays. Liquid in its variety of forms can have a great adverse effect on the performance of LED displays.

The integral LED display parts are easily liable to moisture, resulting in short-circuiting and weak conditions. When an LED screen isn’t in use, the LEDs absorb moisture from the air, whether outdoors or indoors. 

The LED will absorb more moisture when exposed to such high humidity for an extended period. Generally, water and other liquids capable of conducting electricity easily should be kept far away from the LED display. 

However, aside from this safety precaution, there are other ways to protect your indoor and outdoor LED displays from moisture and humidity, which we shall discuss next. Let’s dive in! 

Ways to Protect Your Indoor LED Displays From Humidity

Here are some preventive measures to put in place to ensure the maintenance and durability of your indoor LED display against humidity.

1. Install Dehumidifier and Air Conditioning Units

People often buy an LED display screen, and when the product’s lifespan is not up to par with their expectations, they blame it on poor product quality. However, most times, the problem is a result of poor product maintenance. LED displays are fragile products and should be handled properly indoors or outdoors.

Hence, the first tip on how to protect your LED display from humidity is to install air conditioning units and dehumidifiers. During moist and rainy seasons, air conditioning and reliable dehumidifiers are used to dehumidify the indoor and the LED display area. This helps to prevent the appearance of condensation on the screen. 

Room dehumidifiers shouldn’t be chosen exclusively based on their power and size. Your room’s conditions should also be considered for the best resolution. For instance, If there’s a little moisture in the room, choosing a smaller portative dehumidifier is advisable. 

In Contrast, a damper area will need a large power unit to decrease humidity and dry the area quickly and efficiently. This keeps your Display dry and increases its lifespan.

2. Enclosures and Sealing

Although many indoor LED displays have built-in water resistance to prevent damage, this does not guarantee extreme protection from possible risks. Elevated humidity levels have a high risk of impairing an LED display. One way to control this is using a waterproof enclosure or sealing on the LED screen to offer additional moisture safety. 

Generally, LED vapor-tight fixtures can assist in preventing water stains and expanding the lifespan of the LED display. However, be mindful when using bromine and chlorine disinfectants straight on the LED display screen, as they may compel the weakening of the LED chips and screen.

3. Humidity Monitoring Sensors

Another significant tip on how to protect your LED display from humidity indoor is to equip your LED display panel with a temperature and humidity monitoring sensor to monitor the humidity around your display.

Ideally, the humidity around your Display should not exceed 40-60%. In contrast, the temperature of the fine pixel pitch display should not exceed a temperature of  <30°C and humidity <60% RH for its optimal storage environment. When the proximate humidity of the atmosphere surpasses 65% RH, the LED screen should be dehumidified physically.

Additionally, monitoring the environmental temperature around the LED display daily is advised to ensure it is within the right temperature and meets the working conditions.

4. Frequent Cleaning and Maintenance

Regular Cleaning and Maintenance of indoor LED displays is another way to ensure their protection. Proper care must be taken in cleaning the Display to avoid damage. To ensure its maintenance, the following maintenance recommendations must be noted. 

  • Don’t sprinkle water on the screen while in use.
  • Ensure the LED display is turned off during and after prolonged use. This will help remove moisture buildup caused by the heat dissipating while the TV runs.

5. Ensure Proper Ventilation

One means to secure the LED display’s durability is to make sure the environment where it is kept is suitably ventilated with low-humid air. To aid the evaporation of indoor water, ensure windows are open when the weather is clear, thus reducing the close humidity of the indoor environment.  

Although ventilation devices are often installed on LED displays, ensure that the display screen is installed and kept in a suitably ventilated area, which will aid in reduced moisture assemblage in the surrounding atmosphere of the screen. It can aid in the fast moisture evaporation and reduce the indoor relative humidity.

6. Acquire LED Displays Made From Moisture-Resistant Materials 

Moisture-proof of LED display screens has been an issue of worry and concern for end users. To address this issue, many LED display producers have been devoted to heightening the protection capacity of LED display screens to improve the product quality and longevity of the protected LED display. 

This addresses the users’ problems and solves the industry pain point. When it comes to LED display protection, the water-proof and moisture-proof methods are two efficient ways to guarantee the protection of the Display. While most people often mistake them as the same, they are different. 

Waterproof methods avoid water absorption, while moisture-proof measures aim to keep off humidity and moisture. While it is good to buy waterproof LED displays, it is more advisable to go for moisture-resistant LED displays, ensuring a longer lifespan for your indoor LED display.

7. Install Anti-Condensation Heaters

Anti-condensation heaters are created to maintain the temperature of an electrical chamber. It helps to keep the air inside the electrical panel warm and ensures that dew points and water droplets are prevented from forming on the component. They eliminate the water vapor inside the enclosures and provide frost protection by maintaining the internal temperature of electrical enclosures above freezing temperature. 

Anti-condensation space (Panel) Heaters help prevent condensation through convection— transferring heat through the bulk movement of molecules within fluids such as liquids and gases. Mounting an Anti-condensation heater in the room where your indoor LED display is kept helps to protect it from malfunctions, unwanted failures, and extreme component wear. 

To prevent the formation of condensation, it is therefore sufficient and paramount to keep the temperature inside the panel a few degrees above the dew point temperature. This can be achieved through the installation of one or more anti-condensation heaters.

8. Use Desiccants

A desiccant is a hygroscopic material used to maintain and ensure a state of dryness. It helps to remove and prevent humidity from the air. This creates a moisture-free atmosphere, unlike a humectant that promotes moisture retention.  

Moisture in electronics can result in permanent damage and corrosion. This is applicable even with LED displays. However, with the use of desiccants, this damage can be deterred. Using desiccant can help to lessen the moisture in the air and keep the indoor environment where the LED display is kept dry by absorbing the moisture in the room. 

Your mind is sure to be at rest because, with these desiccants, you don’t have to worry about your LED display getting damaged by water. While many types of desiccants exist, the most commonly used are clay and silicone gel.

9. Follow Manufacturer Guidelines

A common mistake most people make when it comes to electronics is that they don’t bother reading the manual that comes with the electrical appliances. Most people think it’s a waste of time and then resort to doing it alone because they feel they know how to install appliances. 

Then, when anything goes wrong, they blame it on the product. However, no matter how knowledgeable you think you are, those user guides added to the appliance will make your work easier and faster. This is because the product manufacturers who put the guide there already know how their products work. 

Following these guides will help prevent any damage from the wrong installation. This is also why most manufacturers go as far as including a warranty certification. These certifications were included so that if any fault came from using their appliance with the guide, they would be held accountable for the damage. 

This is to show you that they have trust in their products, and for you to use the product the right way, you also have to trust them by following the guidelines in the manual. This is also a good way to protect your LED display from humidity because reading the manual will help you understand what temperature works for the LED display and the right way to maintain the product.

10. Regular Sensor Calibration

As you are already aware, a humidity sensor, better known as a hygrometer, helps monitor and measure the moisture content in the air. It is a one-sure, trusted paddy for controlling and understanding the amount of humidity around us. 

While it is true that these sensors are a trusted means of moisture measurement, we must also take an essential step in ensuring the accurate performance and reliable reading of these humidity sensors. This step is known as calibration. 

Calibrating humidity monitors and sensors regularly is extremely important. This is because it helps ensure that these instruments perform within their producers’ specifications. Through Calibration, you get to know if measurements made with these instruments are accurate so that quality can be preserved.
