How to maintain LED screens in harsh winter weather?

1. Lightning protection measures for the installation building and screen body. In order to protect the display screen from strong electromagnetic attacks caused by lightning, the screen body and outer packaging protective layer of the display screen must be kept grounded, and the grounding The resistance of the line should be less than 3 ohms, so that the current caused by lightning can be drained away from the ground wire in time.

2. Waterproof, dustproof and moisture-proof measures for the entire screen

Seamless connections must be made at the connection between the box and the box, as well as between the screen and the force-bearing installation object. , to avoid water leakage and moisture. There must be good drainage and ventilation measures inside the screen so that if water accumulates inside, it can be dealt with promptly.

3. Regarding the selection of circuit chips

In the northeastern region of my country, the temperature in winter can generally reach minus ten degrees, so when choosing a circuit chip, you must It is necessary to choose an industrial-grade chip with an operating temperature of minus 40 degrees Celsius to 80 degrees Celsius to avoid the situation where the display cannot be started due to too low temperature.

4. Ventilation measures must be taken inside the screen

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 environment temperature to be too high, which will affect the work of the integrated circuit. In severe cases, it may cause burnout, and the display will not be able to operate. Therefore, ventilation and heat dissipation measures must be taken inside the screen to keep the temperature of the internal environment between minus 10 degrees and 40 degrees. 5. Selection of high-brightness wicks

Choosing LED tubes with high luminous brightness allows us to still display good results under direct sunlight, and can also enhance the contrast with the surrounding environment, making the picture more accessible to a wider audience, even at long distances and with a wide viewing angle. There are still good performances.
