According to statistics, every year more than 1/4 of the industrial electronic products are damaged by moisture in the world . The harm caused by moisture seriously affects the quality and service lifetime of the industrial electronic products. As a new type of media display product, LED displays are widely used worldwide. Because of their high brightness, seamless connecting, bright colors and long service lifetime, LED displays are widely used for indoor and outdoor fixed installation and rental, such as shopping mall, commercial media, cultural performances, stadiums, public transportation and many other fields.
Due to the waterproof design of the product and a series of technical treatments and quality control during the manufacturing process, the LED displays can be used in harsh outdoor environments. Before the production, the electronic components will be dried, applied three proofing treatments(mold proof, moisture proof and salt spray proof) etc. After being assembled into a finished product, they will be subjected to rigorous tests such as waterproof, high and low temperature, and vibration test to ensure the stability and reliability of the LED displays. However, as the use time of the LED displays gets longer, and the weather changes, the probability of the LED displays getting damp will increase, the reason is that most of the electric components of the LED displays are moisture-sensitive devices, which are easily get damp during operation.
Here are some suggestions to maintain the LED displays:
First of all, we start with the storage of raw materials and moisture prevention in the manufacturing process. As the most important component of the LED displays, LED lamps are the components which most susceptible to moisture and can not be repaired. The mainly packaging material of LED lamps is epoxy resin (a kind of polymer material), while polymer materials have the characteristics of moisture absorption, so the vaporized water molecules can easily enter the package shell, which causes the LED lamps to become damp.
So how do we effectively prevent moisture from the LED lamps? There are several methods as following:
Below are the methods to protect the LED displays from moisture:
For the LED displays screen, in addition to the moisture proof methods we introduced above, the most effective method is to let the LED display work for a period of time every day. Because the LED display will be heated up when the device is working, and the heat can evaporate the water vapor, which greatly reduces the probability of the LED display being damp.
If the LED screen has not been used for more than 7 days, when we turn on the LED display, we should warm it up at first. The suggestion method to warm up and turn on the LED display is: warm up for more than 12 hours at the brightness of 30% ~ 50%, and then light up the LED displays by adjusting the screen brightness to a normal brightness (80% ~ 100%) ), in this way, the moisture inside the LED displays can be removed and there will be no abnormality during the operation.
The daily maintenance of the LED display is really important, proper maintenance can effectively extend the service lifetime of the LED display, reduce the frequency of maintenance, reduce the maintenance cost, improve the efficiency of usage, and most importantly, it brings higher benefits for you.
