With the development of LED display module, the usage rate is rising cause more customers have realized that it is a beneficial tool to expand businesses and bring more profits. However, sometimes the daily maintenance of LED display panel may be neglected, and lifespan of the product can be reduced and the visual effect may be weakened. If you want to know how to ensure the stable performance of the LED displays, there is some practical advice for you to take.

1. Surrounding Environment

The recommended working temperature is -20℃~50℃, and the humidity shall be 10%~ 90%RH. Dampness may lead to corrosion of electronic parts, short circuit or even permanent damage. For more details about anti-moisture instructions, you can refer to LED Display Screen Moisture-proof Instruction.

1. Avoid use or place your LED display modules in an inappropriate environment with high temperature, high humidity, high acid or other extreme conditions. If there are flammable materials, too much gases or dusts, there may not be a good place for you to place your LED displays. For instance, too much dust may hurt the circuit.

2. When the ambient temperature is too high or the heat dissipation can not be implemented well, the LED display board should not be under running for a long time.

2. Starting Up & Turning Off

For starting up, you should turn on the PC and then turn on the display when using the display.

When it comes to turning off your LED screens, the sequences should be: first, LED display; second, control software; finally, computer. If you turn off the computer firstly, it may cause serious consequences such as bright points and burning out.

Besides, the interval between switching on and off should be at least 1 minute. Do not play in full white, red, green, blue, and other full-bright screens for a long time, as the LED screen will be at maximum power and result in the greatest impulse current to the entire power distribution system.

 

 

3. Power Supplying

1.The use of AC power is prohibited, and don’t make positive and negative of the power oppositely. If it happens, burning out may be caused or even worse – fire disaster. And the supply voltage should be 220V ± 10% and 50HZ ± 5%.

2.If some abnormal situations appear, for example, short circuit and tripping, don’t attempt to figure out by powering the LED display module repeatedly before you have targeted the problem in time.

3.Grounding protection is necessary to prevent from been struck by lightning. The lightning protection facilities must be checked frequently and you need to inspect the lightning rods and grounding circuits regularly.

4.Power your large LED display screen gradually, as the maximum power may overload the power distribution system.

In order to avoid excessive current and other emergencies to the LED lamp beads, don’t play all white pictures with the highest brightness for more than half an hour.

4. Cleaning

With prolonged exposure to the wind, sun, rain and dust, LED display module may accumulate dampness, dust or other pernicious materials. Keeping your LED screens clean and tidy sometime can be challenging. Therefore, there are a few effective and harmless cleaning suggestions you can put into practice.

There are a few types of cleaning cloths recommended. The most recommended one is microfiber cloth because of many reasons. First, it is thin and soft while can thoroughly clean the electronic devices and minimum the possibility of damage. Second, these cloths are able to trap larger quantities of dirt and dust as the minuscule fibers intertwined on it. The other recommendations are cotton tea towel, or a cotton handkerchief and some cloths made up of cotton if you don’t have microfiber on hand. Also, you can use soft brushes when cleaning the surface. Please remember don‘t use liquid directly to clean the modules as far as possible.

5. Moistureproof and Storage Ways

1. The temperature requirements of storage: -40℃≤t≤60℃; and after opening the package, the LED products shall be stored when temperature <30℃ and humidity <60%.

2.If your LED display module is power off for many days, a recommended method is to bring up the brightness from a low gray level which can heat the LED boards gradually. There are steps below:

 

Power-On Hours for Different Gray Levels

 

6. Hardware and Software

If there are dots out of control or abnormal modules, please check all the hardware if possible, including whether there are problems that happen on the wiring connection, fans, ventilation filters, etc. And whether the socket is plug-in correctly and so on.

Don’t forget your content can’t run unless the software side of things is taken care of. You need to test the LED display control system including the consistency of the LED screen. For example, whether there are flickers, abnormal color and uneven brightness while showing the images. The management system and antivirus software will need to be kept up-to-date.

 

7. Other Aspects

1.Choosing the protection methods between passive protection and active protection based on the consideration of reducing the harm to your indoor or outdoor LED display modules.

2.Let your outdoor LED display screen have a rest, more than 2 hours a day is a recommended frequency. In the rainy season, turn on large outdoor LED display screen at least once a week and turn on the screen at least once a month for up to 2 hours.

The lifespan of a LED display module is not only related to the raw materials and production processes but also closely related to the daily maintenance. To prolong the service life of LED display, we must develop the habits of maintenance and implement the habits strictly.
