How to Clean LED Video Wall?

Do outdoor LED displays​ need cleaning? Undoubtedly, the answer is yes. After being used for some time, LED display bodies would be covered with dust, impurities, dirt, etc, which will, if not cleaned up, adversely affect their operation, and even destroy the displays. Therefore, outdoor LED displays need to be cleaned regularly to ensure their excellent display effect.

LED display cleaning is a high-altitude operation which requires a professional cleaning team. The cleaning operation is conducted using a high-altitude hanging rope together with professional cleaning equipment. The cleaning staff selects different cleaning agents for targeted cleaning according to the sort of dirt on the screen, thereby ensuring that the cleaning is completed without damaging the LED lamps and masks. 

 

Three steps of the cleaning work: 

 

Step 1: Vacuuming. The dirt and dust on the surface of the display mask be removed at first. 

 

Step 2: Washing. Water spray and steam humidification should be sprayed to the screen mask before a soft brush on the vacuum cleaner be used to scrub the lamp mask so as to clean the dirt. 

 

Step 3: Drying. A vacuum cleaner should be used to absorb the water drops and water marks left after the washing step to ensure that the display screen is clean and dust-free. 

 

Cleaning before and after installation of outdoor LED displays: 

 

1. Cleaning before installation:  

 

The current LED display is a semi-finished product, a LED module that has not been installed with a kit. The cleaning at this time should apply a special washing water. Dip the LED module with some washing water before brushing it with a brush to accelerate the dissolution of rosin and the removal of flux and remove dust and impurities. The step is done by the manufacturer. 

 

2. Cleaning after installation: 

 

In order to remove the dust and impurities accumulated after a period of time, you must first consider purchasing a cleaning kit of better quality. The composition of the cleaning solution generally includes the electrolyte, high-purity distilled water, and antistatic liquid which effectively clean dust and other marks. Some netizens think that pure water could also be used and it will not affect the outdoor LED display. 

 

However, the cleaning effect of clean water is poor, and the dust will adhere again after cleaning. Of course, if you want to save money, you can use clean water which is better than cleaning liquids of unknown origin. At the same time, it should be noted that you must not spray water on the screen. You can spray a little cleaning liquid on the cleaning cloth, and then gently wipe with it in the same direction. Before cleaning, you need to pull out the power cord. 

 

Cleaning steps of LED display components: 

 

1. Cleaning of the internal side of the cabinet:

 

For displays with lower protection levels, especially outdoor screens, dust in the atmosphere entering the device through the ventilation holes accelerates the wear and tear of the fan and other devices; it will also fall on the surface of the control device inside the display reducing thermal and insulation performance. In wet weather, dust absorbing moisture in the air causes a short circuit; it can also cause mold mildew on PCB boards and electronic components in a longer term, which undermines and further cease the technical performance of the equipment.

 

Therefore, the cleaning of the display device, which seems to be simple, is actually an important part of the maintenance work. When cleaning the dust inside the display, remember to disconnect the power and operate with care.   

 

2. Cleaning of the surface of the screen body:

 

After being used for a long time, the dust and impurities accumulated on the surface of the surface must be cleaned. In order to remove the dust and impurities accumulated after a period of time, you must first consider purchasing a cleaning kit of better quality. The composition of the cleaning solution generally includes the electrolyte, high-purity distilled water, and antistatic liquid which effectively clean dust and other marks. 

 

At the same time, it should be noted that you must not spray water on the screen but spray a little cleaning liquid on the cleaning cloth, and then gently wipe with it in the same direction. Before cleaning, you need to pull out the power cord. A vacuum cleaner should be used to absorb the water drops and water marks left after the washing step to ensure that the display screen is clean and dust-free. 

 

3. Cleaning of the LED module:

 

Before the LED module is installed, you need to clean it with special washing water. First, dip the LED module with this special washing water and then brush it (note: remember do not add too much at one time). This can accelerate the dissolution and shedding of rosin and achieve a good effect of removing dust and impurities. 

 

Points to attention when cleaning the display: 

First, consider purchasing a cleaning kit of better quality. The composition of the cleaning solution generally includes the electrolyte, high-purity distilled water, and antistatic liquid which effectively clean dust and other marks. 

 

Second, some netizens think that pure water could also be used, and it will not affect the outdoor LED display. However, the cleaning effect of clean water is poor, and the dust will adhere again after cleaning. At the same time, it should be noted that you must not spray water on the screen but spray a little cleaning liquid on the cleaning cloth, and then gently wipe in the same direction. Before cleaning, you need to power the power cord Pull out. 

 

The cleaning of the display is very important whether before or after the screen is installed. Regular cleaning and maintenance of the LED display can effectively extend the life of the LED display.
