How to clean: Outdoor LED displays are gradually entering the "high-definition" era, and the display effect and color reproduction of the picture are particularly important. In addition to uniformity, grayscale, refresh rate, contrast, color gamut and color temperature, the factors that determine these effects are also affected by dirt and dust. Therefore, the outdoor LED display needs to be cleaned regularly to ensure the display effect of the LED screen.
LED electronic display cleaning is a high-altitude operation and requires a professional cleaning team. The cleaning operation adopts the high-altitude rope method (commonly known as Spiderman) or a hanging boat, equipped with professional cleaning equipment. The cleaning personnel choose different cleaning agents according to the different dirt on the screen for targeted cleaning, so as to ensure that the cleaning of the LED electronic display screen is completed without damaging the LED lamp tube and mask.
Cleaning and maintenance are divided into three steps:
Step 1: Vacuuming. First, remove the dirt and dust on the surface of the display screen mask.
Step 2: Wet cleaning. Use water spray and steam humidification to spray the display screen mask, and use the soft brush on the vacuum cleaner to brush the lamp tube mask to clean the dirt.
Step 3: Drying. Use a vacuum cleaner to suck up the water droplets and water marks left after wet cleaning to ensure that the display screen mask is clean and dust-free.
Outdoor LED display screens need regular maintenance to achieve the best display effect
