Outdoor LED displays usually appear in the form of outdoor media. Outdoor media refers to the media that publish advertising information on the roofs of major buildings, in front of doors in commercial areas, on the roadside and other outdoor venues. Because the outdoor display screen has a large area and works in the sun for a long time, it is inevitably covered with dirt and dust, thus affecting the display effect and color reproduction of the display screen. In order to ensure its display effect, we need to regularly clean and maintain the outdoor LED display screen. The cleaning work needs to be equipped with a professional cleaning team, usually using a high-altitude rope (commonly known as spider man) or a crane boat, equipped with professional cleaning equipment, according to different dirt to select targeted cleaning, so as to ensure that the cleaning work is completed without damaging the led lamp beads and masks. First of all, you should buy a cleaning kit with excellent quality (you can't use clean water directly). The cost of cleaning solution generally includes electrolyte, high-purity distilled water, antistatic liquid, etc., which can effectively clean the dust and other stains on the LED display screen. Before cleaning, you need to pull out the power cord, spray a little cleaning solution on the cleaning cloth, and gently wipe it in the same direction.
