First, the display to clean up the work
For the lower degree of protection of the display, especially the outdoor screen, the air easily from the ventilation holes into the device, will accelerate the equipment and other equipment, such as wear and even damage. Dust may also fall on the surface of the control device inside the display, reducing thermal conductivity and insulation performance. Dust in the face of moisture can cause short air in the air. Long term damage to the PCB and electronic components can cause the device The technical performance of the decline, a failure. Therefore, the cleaning of the display looks simple, but in fact is a very important step in the maintenance work.
Second, the regular display of the fastening of the connection
LED display is a high power consumption equipment, when running for some time, due to multiple start and stop operation, which power supply part of the terminal due to hot and cold will cause loose, contact is not strong, the formation of virtual joint, serious heat Ignite the plastic parts next to it. Signal terminals will also be due to ambient temperature hot and cold changes loose, moisture erosion caused by poor contact, which led to equipment failure, it must be on the LED display connector for regular fastening. In the fastener adjustment, should be forced evenly and appropriate to ensure that strong and effective.
Third, the regular surface cleaning work on the display
LED display cleaning is a high-altitude operations, need to be equipped with professional cleaning team. Cleaning operations using high-altitude sling way (commonly known as Spider-Man) or the use of hanger, configure the professional cleaning equipment, cleaning personnel according to the screen on the different dirt to choose a different cleaning agent targeted cleaning, so as not to damage the LED lamp And the mask under the premise of the completion of the display cleaning work. Cleaning need to pay attention to two points: First, before cleaning, need to pull out the power cord. Second, the choice of cleaning fluid, cleaning fluids generally include electrolytes, high purity distilled water, anti-static liquid, etc., to choose good quality, in order to effectively clean the screen dust and other stains.
