Static electricity is a major killer of LED displays. It not only reduces the life of the display, but can even discharge and breakdown the electronic components inside the display, damaging the screen. Whether it is an indoor LED display or an outdoor LED display, static electricity is easily generated during use, causing safety hazards to the display. By adding a grounding wire to the display screen, the static electricity generated by the display screen can be transmitted to the earth in a timely manner; in addition, workers must wear an electrostatic bracelet when operating the display screen to prevent screen damage caused by static electricity carried by the human body.
Condensation is also a huge threat to LED displays and is extremely harmful to outdoor displays. Although the outdoor display screen will be waterproofed, condensation is caused by the condensation of water vapor in the air, and small droplets will adhere to the surface of the PCB board and module of the display screen. If waterproofing is not done, the PCB board and module will be corroded, resulting in reduced lifespan or even damage to the LED display. The solution is to choose a display with a coated waterproof coating when purchasing a display, or apply a layer of conformal paint to the screen body.
Low-temperature environments will also affect the operation of LED displays. Most outdoor LED displays operate in a temperature range of -20°C to 60°C. Too low a temperature will cause the activity of some semiconductor components to decrease, or even prevent normal startup. Others Plastic components may crack due to freezing temperatures. Therefore, when purchasing an LED display, try to pay attention to its working temperature. Do not light up the LED screen when the temperature is too low, and regularly check whether the screen is damaged. In extreme cold conditions, you can install a heater on the display. device.
