1. Lightning protection measures for installation of buildings and screens
In order to prevent the display screen from being subjected to strong electromagnetic attacks caused by lightning, the screen body and outer packaging protection layer of the display screen must be grounded, and the resistance of the grounded circuit should be less than 3 ohms, so that the current caused by lightning can be discharged from the ground wire in a timely manner.
2. Waterproof, dustproof, and moisture-proof measures for the entire screen body
Seamless connection should be achieved at the connection between the box and the box, as well as at the connection between the screen and the load-bearing installation object, to avoid water leakage and moisture. Good drainage and ventilation measures should be taken inside the screen body, so that if there is water accumulation inside, it can be treated in a timely manner.
3. On the Selection of Circuit Chips
In the northeast region of China, the temperature in winter can generally reach around minus ten degrees Celsius. Therefore, when selecting circuit chips, it is necessary to choose industrial grade chips with a working temperature of minus 40 degrees Celsius or 80 degrees Celsius to avoid situations where the display screen cannot start due to low temperatures.
4. Ventilation measures should be taken inside the screen body
When the screen is powered on and running, it will generate a certain amount of heat. If this heat cannot be discharged and accumulates to a certain extent, it will cause the internal environmental temperature to be too high, which will affect the operation of the integrated circuit. In severe cases, it can cause burning, and the display screen cannot operate. Therefore, it is necessary to take good ventilation and heat dissipation measures inside the screen, and maintain the temperature of the internal environment between -10 ° C and 40 ° C.
