Q: The display screen is installed outdoors, where it is often exposed to the sun and rain, and wind and dust blow the cover, creating a harsh working environment. Electronic equipment that is wet or severely damp may cause short circuit or even fire, causing malfunction or even fire, resulting in losses;
A: The screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures so that it can be drained smoothly once water accumulates.

Q: The display screen may be attacked by strong electricity and magnetism caused by lightning;
A: Install lightning protection devices on display screens and buildings. The main body and shell of the display screen should be well grounded, and the grounding resistance should be less than 3 ohms, so that large currents caused by lightning can be discharged in a timely manner.

Q: The ambient temperature changes greatly. The display itself generates a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, causing the display system to fail to work properly;
A: Install ventilation equipment to cool down the screen so that the internal temperature of the screen is between -10°C and 40°C. An axial flow fan is installed above the back of the screen to discharge heat.
