Although the LED electronic large screen has a long viewing distance and high brightness, if it is in the haze weather for a long time, it will also cause different degrees of damage to the screen. So when the outdoor LED electronic large screen encounters the haze weather, how to solve it, and what kind of harm will the haze weather cause to the screen? The following is a brief analysis by the mini photoelectric LED display manufacturers.
Hazards and solutions of haze in outdoor LED electronic large screen
First of all, what is haze? The main components of haze weather are the mixture of sulfur dioxide, nitrogen oxides and inhalable particles. The first two are gaseous pollutants, which combine with fog to make the sky gray instantly. Fog itself is a non-toxic and harmless natural phenomenon, but the formation of haze is mainly caused by a large number of particles suspended in the air and meteorological conditions. Condensation and haze often occur in case of temperature inversion.
So what kind of harm will haze do to LED electronic large screen? Since there is often water vapor in foggy places, it means that the humidity in the air is very high, and the water vapor will flow into the screen through the air, causing the LED electronic large screen to be affected by moisture. If the humidity is too high, the PCB board, power supply and power line of LED electronic large screen will be easily oxidized and corroded, or even short-circuit, and then failure.
Haze often has a lot of suspended dust, which will enter into the LED display through the ventilation holes, and even accelerate the wear or damage of fans and other equipment. If dust enters the surface of the control device inside the LED display, it will not only reduce the heat dissipation and insulation performance of the display, but also accelerate the aging of the display, affecting the normal service life of the screen.
Therefore, customers must pay attention to protection before purchase and after use. Before purchasing, we must see the dust-proof level of LED electronic large screen produced by LED display manufacturers. As for the dust-proof level, the international standard is ipox-ip6x, which is a design level to prevent the invasion of foreign matters. If it is installed in the northern areas with more sand and haze weather, it is required that the protection level of the front and back of the LED electronic large screen must reach IP65, that is, it must adopt complete dust-proof structure, that is, it must be sealed in the state of spraying water. The protection grade of LED outdoor display produced by mini photoelectric LED display manufacturers is IP65. For some customized products, the protection grade can reach IP68, which can be used in haze, rain, high temperature and other weather conditions.
In addition, after SMD lamp beads and driving IC are packaged, mini LED display manufacturers will carry out anti-corrosion treatment on PCB, that is, coating three anti paint on the surface, which can play the role of anti-corrosion, dust prevention and moisture resistance. In addition, select the advantage of power supply and power cord, and check whether the screen welding is easy to be corroded during the installation process, and whether it has done antirust treatment.
In addition, end users should pay attention to regular dust removal during use, or let LED display manufacturers send technology to regular maintenance and inspection. Avoid wet weather dust absorption of moisture in the air, resulting in screen short circuit, and even PCB and electronic components mildew and other situations.
The above is the mini photoelectric LED display manufacturers brief analysis of outdoor LED electronic large screen encountered haze hazards and solutions. Haze weather will produce a lot of water vapor and dust. If it enters into the screen, it will lead to short circuit, oxidation, corrosion and mildew of electronic components, which will damage the screen and affect the service life of the screen. Therefore, customers should recognize the protection level when purchasing products, and carry out regular cleaning and maintenance.
