The impact of smog on outdoor high-brightness LCD advertising machine

Many cities in northern China often see gray skies in the morning, especially in winter, because of the rapid development of many heavy industries, the gray sky is actually a thing called smog. It is estimated that many people do not know what is smog, its main constituent substance is formed by a mixture of sulfur dioxide, nitrogen oxides and respirable particulate matter, the former two are gaseous pollutants, which combine with the fog to make the sky instantly gray. In fact, fog is a non-toxic and harmless natural phenomenon, and the formation of haze is mainly the result of a large number of particles suspended in the air and meteorological conditions.

Smog is often accompanied by haze, haze appears at the same time, water vapor, static wind, temperature inversion, condensation nucleus and other conditions are indispensable. Haze is a collection of dust suspended in the air, various tiny particles, etc., of which the dust particles suspended in the air are the core substance of haze. If under the influence of haze for a long time, all kinds of fine dust in the air will enter the equipment by the ventilation hole, and the equipment such as fans will accelerate wear and even damage, and the dust will fall on the surface of the internal control device of the outdoor high-brightness LCD advertising player, which not only reduces the heat dissipation and insulation performance of the display, but also accelerates the aging of the display and affects the normal service life.

The toxins in the smog not only seriously endanger people's health, but also have a great impact on the operation of outdoor high-brightness LCD advertising machines. In fact, you can distinguish between haze and haze, because the main harm of the two to the display is not the same.

1. The harm of fog to outdoor high-brightness LCD screen advertising machine
Fog is formed by the condensation of water vapor in the air. That is to say, the humidity in the air is relatively large, which will cause the LED display to be damp. Excessive humidity will cause the PCB board, power supply, power cord and other devices of the display to be easily oxidized and corroded, or even short circuit, and then produce failure.
