Cleaning Outdoor Advertising LED display

Why it is important to clean the outdoor LED display screen?

It is important to clean the outdoor LED display screen regularly after screen installation.

In outdoor environment, weather is always changing with day and night, rainy and sunny day.

With changing environment makes changing temperature which also carry dust, water and debris to the surface of the outdoor LED advertising display.

Dust in the atmosphere enters the outdoor LED display screen through the ventilation holes, which will accelerate the wear and tear or even damage the equipment such as fans.

Dust will also fall on the surface of the internal control device of the display, reducing the thermal conductivity and insulation performance.

In humid weather, the dust absorbs moisture in the air and causes a short circuit.

It can also cause mildew on the PCB board and electronic components in the long term, resulting in a decline in the technical performance of the device.

Therefore, the cleaning of the LED display may seem simple, but it is actually a very important part of the maintenance work.

Prevent heat up

Besides, LED display screen is a high power consumption equipment.

After running for a long time, the wiring terminal of the power supply part will become loose due to cold and heat, and the contact will become loose.

In severe cases, it will heat up, or even Ignite the plastic component next to it.

Other reasons for regular cleaning of outdoor LED display

The signal wiring terminals will also become loose due to changes in the ambient temperature.

And moisture erosion will lead to poor contact, which will lead to equipment failure.

Therefore, it should tighten the LED display connector regularly.

When adjusting the fasteners, the force should be even and appropriate to ensure firmness and effectiveness.

If it is not cleaning regularly, the LED display will gradually showing unclear and blurry image existed.

Regular cleaning the LED display can also extend the service life of the device. So, what shall we do for the inspection and cleaning of the outdoor display screen?

Cleaning of the LED display screen

It is necessary to regularly check the integrity of the seal. For the outdoor screen steel structure, check the surface paint and rust.

Pollution is particularly serious for the outdoor screen surface.

If the cleaning of the LED display is a high-altitude operation, a professional cleaning team is required.

The cleaning operation adopts the high-altitude sling method (commonly known as the spider man) or the hanging blue, equipped with professional cleaning equipment.

The cleaning staff chooses different cleaning agents according to the different dirt on the screen to clean in a targeted manner, so as to ensure that the LED tube is not damaged.

Cleaning and maintenance is divided into three steps:

The first step: vacuuming.

First suck and sweep away the dirt and dust on the surface of the display mask.

The second step: wet washing.

Note that you can’t spray the lotion directly on the screen, but spray a little cleaning liquid on the cleaning cloth, and then gently wipe in the same direction. You can also use the soft brush on the vacuum cleaner to scrub the lamp mask to clean the dirt.
