Cleaning and precautions for LED display
As a medium for indoor and outdoor display, LED electronic display screen will inevitably fail due to factors such as pollution, looseness, vibration, heat, and large temperature changes, which will affect the normal use of the display screen. Therefore, regular cleaning and maintenance of the display screen is essential. So what do we mainly do on a daily basis?

1. Clean up
For display screens with lower protection levels, especially outdoor screens, dust in the atmosphere enters the device through the ventilation holes, which will accelerate wear and tear or even damage to fans and other devices. Dust will also fall on the surface of the control card device inside the display screen, 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 for a long time, resulting in the technical performance of the device. Descends, malfunctions. Therefore, the cleaning of the LED display screen seems to be simple, but it is actually a very important part of the maintenance work.

2. Fastening
The LED display screen is a high-consumption equipment. After running for a long time, due to repeated start-stop and operation, the connection terminals of the power supply part will be loose due to cold and heat, the contact is not firm, and a virtual connection is formed. Ignite the plastic components next to it. The signal terminals will also loosen due to changes in ambient temperature and heat, and moisture erosion will lead to poor contact, which will lead to equipment failure. Therefore, the connectors of the LED display must be fixed regularly. When adjusting the fastening device, the force should be even and appropriate to ensure firmness and effectiveness.

3. Clean the display surface
Visually inspect and inspect the LED display in two states of bright screen and black screen. Including: whether the surface of the display screen is polluted, the purpose is to understand the influence of the surface dirt on the luminous characteristics; whether there is damage and cracks on the surface of the display screen; whether the communication and distribution cable lines are normal; Therefore, it is necessary to regularly check the integrity of the seal; for the outdoor screen steel structure, check the surface paint and rust; for the outdoor screen surface pollution is particularly serious, also To clean the display surface.

LED display cleaning is a high-altitude operation, and a professional cleaning team is required. The cleaning operation adopts the method of high-altitude sling (commonly known as spider man) or the use of hanging baskets, and is equipped with professional cleaning equipment. The cleaning personnel should choose different cleaning agents according to different dirt on the targeted cleaning, so as to ensure that the LED lamps are not damaged. Complete the cleaning of the display screen under the premise of and the mask.

There are two points to pay attention to when preparing for cleaning:
1. Unplug the power cord before cleaning.
2. The choice of cleaning liquid, the cleaning liquid generally includes electrolyte, high-purity distilled water, antistatic liquid, etc., to choose good quality, in order to effectively clean the dust and other stains on the LED screen.

Cleaning and maintenance is divided into three steps:
The first step of vacuuming: first vacuum and sweep the dirt and dust on the surface of the display mask.
The second step of wet cleaning: Be careful not to spray the cleaning liquid directly on the screen, but to spray a little cleaning liquid on the cleaning cloth, and then gently wipe it in the same direction. You can also use the soft brush on the vacuum cleaner to brush the lamp mask to remove the dirt.
The third step of drying: Use a vacuum cleaner to absorb the water marks left after wet cleaning to ensure that the display mask is clean and dust-free.
