Daily maintenance of outdoor led display

With the rapid development of science and technology, large-screen display products have gradually become an indispensable part of our daily life, especially the outdoor led display is closely related to our lives, and it can be seen everywhere in the city. Whether in the business center, sports center or dance stage, outdoor led display plays an important role.

Outdoor led display as a long-term use of the product, the general service life of more than five years, then during this period to regularly maintenance and maintenance, in order to better ensure normal use and extend the service life.

Outdoor led display in the use of the process, there are many reasons for damage, need to waterproof, dustproof, heat dissipation, anti-corrosion, anti-static, anti-lightning, anti-small animals, and regular maintenance and overhaul.

1.Reasonable use and operation of outdoor led display screen

In the process of long-term use, long-term high brightness display should be avoided to prevent lamp beads from being damaged due to overheating. In addition, the working status of the led display should be checked regularly, and timely measures should be taken if anomalies are found. During operation, pay attention to avoid excessive vibration and collision, so as to avoid loosening or damage to the internal components of the display.

2.Clean the outdoor led display regularly

♦Cabinet interior cleaning

For outdoor led screen panel, dust in the atmosphere enters the device through the ventilation hole, which will speed up wear and even damage equipment such as fans, and dust will also fall on the surface of the internal control devices of the display screen, reducing thermal conductivity and insulation performance. In the case of wet weather, dust absorbs moisture in the air leading to short circuit, long-term can also lead to PCB board and electronic components mildew, resulting in the technical performance of the equipment decline, failure, so the cleaning of the display equipment seems simple, in fact, is a very important way in the maintenance work. When cleaning the dust inside the display screen, remember to disconnect the power supply and operate carefully.

♦ Screen surface cleaning

After the LED electronic display is used for a long time, the dust and impurities accumulated on the surface of the screen should be cleaned. First of all, we must consider the purchase of a better quality cleaning set, the cost of cleaning liquid, can effectively clean the dust and other stains on the LED screen. At the same time, it is important to note that we must not spray water on the screen, but to spray a little cleaning liquid on the cleaning cloth, and then gently wipe along the same direction, and before cleaning, you need to pull out the power cord. Finally, use the vacuum cleaner to absorb the water droplets and water marks left after dry and wet washing to ensure that the display mask is clean and dust-free.

3.Waterproof and lightning protection maintenance measures for outdoor led display

Due to the unpredictability of the outdoor environment, outdoor led displays are vulnerable to erosion by rain and wind. Therefore, in the installation and maintenance of outdoor led display, it is necessary to ensure its good waterproof performance, which includes the use of waterproof sealant to seal the outer frame of the led display to prevent moisture infiltration into the interior. In addition, we can also use a waterproof cover or waterproof shell to protect the led display to prevent rain from directly contacting the surface of the led display, and lightning protection devices should be installed to prevent lightning strikes from causing damage to the led display.

4.Fastening of outdoor led display board

Large-scale LED display is a high power consumption equipment, after running for quite a period of time, due to multiple start and stop and operation, the power supply part of the terminal due to cold and heat will cause loose, contact is not strong, serious heat ignition next to the plastic components, signal terminal will also due to the environmental temperature changes loose, moisture erosion leads to poor contact, resulting in equipment failure, Therefore, the tightness of the connecting parts in the equipment must be checked frequently. When fasteners are adjusted, they should be forced evenly and properly to ensure firmness and effectiveness.

In general, the maintenance of outdoor led displays is the key to ensuring their normal operation and extending their life. Regular cleaning, waterproof and lightning protection, regular inspection and maintenance and rational use and operation are essential maintenance measures, only the correct maintenance and maintenance, in order to better enjoy the visual experience and economic benefits brought by outdoor led display.
