How to waterproof and moisture-proof LED display in rainy season? After mid-to-late May, the "plum rain weather" came as scheduled, and the phenomenon of heavy rain flooding the city continued to take place. We know that the lamp beads of the display are MSD components (humidity sensitive devices), so this wet and rainy weather is a big challenge for full-color LED displays. So how to deal with the problem of moisture ingress or even water ingress in the LED display during the rainy season?
The challenge of the climate in southern China to LED display devices in summer
LED display should pay attention to ventilation and dehumidification
For indoor display screens, first of all, moderate ventilation. Proper ventilation can help the water vapor attached to the display to evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in some windless and humid air, which will increase the indoor humidity; secondly, place a desiccant indoors and use physical moisture absorption methods to reduce the moisture in the air; or turn on the air conditioner to dehumidify, if the display If an air conditioner is installed in the installation space, the air conditioner can be turned on for dehumidification in humid weather.
LED display focuses on waterproofing
El entorno de la pantalla LED exterior en sí es más complicado que el interior, y se pueden usar métodos interiores para evitar la humedad, pero la pantalla exterior no solo debe considerar el problema de la humedad, sino también realizar el trabajo de mantenimiento diario como la impermeabilización, especialmente en la temporada de lluvias, por lo que es bueno La instalación sellada puede ayudar a la pantalla a reducir el riesgo de ingreso de agua, limpiar regularmente el polvo adherido al interior y exterior de la pantalla, y también ayudar a la pantalla a disipar mejor el calor y reducir la adherencia de vapor de agua.
Moisture entering may cause outdoor LED display dead light
So the most important thing is that the most important thing about outdoor full-color LED display waterproofing is prevention during production and construction.
In the process of use, excessive humidity causes the PCB board, power supply, power cord and other components of the LED display to be more likely to be oxidized and corroded, and cause failure. So this requires that when we make LED displays, the PCB boards should be treated with anti-corrosion, such as coating the surface with three-proof paint, etc., and high-quality accessories should be used for the power supply and power cord. The selected waterproof box has good airtightness, and the screen must reach IP65. Welding is the place most likely to be corroded. Pay attention to the protection work, especially the frame, which is easy to rust, and do a good job of anti-rust treatment.
Secondly, for different unit board materials, professional waterproof coatings are needed. Here is an example of a P10 full-color outdoor LED display. First of all, confirm whether the P10 full-color outdoor unit board is magnetized or screwed (the screwing effect is good, the magnet is slightly worse); secondly, whether there is a waterproof groove on the unit board kit, if there is, the front waterproofing is basically not a big problem, even The unit board is fixed with magnets, there is no problem. Finally, we also need to pay attention to the waterproof problem of the backplane of the outdoor LED display, because in the process of using the display, the backplane LED display is not only a heat dissipation treatment, but also a great convenience in dealing with the waterproof performance. sex. When dealing with the waterproof coating on the back, pay more attention to the waterproof performance of the small strip-shaped display aluminum-plastic panel on the back. Use an electric drill to design a row of drains under the aluminum-plastic panel, which is beneficial to the waterproof of the display and the heat dissipation of the display. The best display processing method.
La otra parte debe implementarse en el sitio de construcción de hormigón; en el diseño estructural se combinan prevención y drenaje; Después de determinar la estructura, de acuerdo con las características de la estructura, se puede considerar que tiene una estructura de tubo de burbuja hueca, una tasa de compresión pequeña y una tasa de elongación de rotura. Material de la tira de sellado con gran rendimiento; Después de seleccionar el material de la tira de sellado, es necesario diseñar una superficie de contacto adecuada y una fuerza de contacto de acuerdo con las características del material de la tira de sellado para hacer que la tira de sellado adquiera una forma densa. En algunas instalaciones, ranuras impermeables y otras ubicaciones, haga una protección clave para garantizar que no haya acumulación de agua dentro de la pantalla. Solo de esta manera se puede utilizar la pantalla de visualización en la temporada de lluvias sin problemas de calidad causados por factores humanos.
Indoor LED displays in high temperature and high humidity areas need to be dehumidified frequently
Por último, tanto si se trata de una pantalla interior como de una pantalla exterior, la forma más eficaz de evitar daños en el funcionamiento de la pantalla es utilizarla con frecuencia. La pantalla en el estado de funcionamiento generará algo de calor, que puede evaporar algo de vapor de agua, lo que reduce en gran medida la posibilidad de un cortocircuito causado por la humedad. Por lo tanto, la pantalla de visualización que se usa con frecuencia tiene un impacto mucho menor sobre la humedad de la pantalla de visualización que no se usa comúnmente. Los expertos de la industria sugieren que la pantalla LED debe usarse al menos una vez a la semana durante la temporada de lluvias, y la pantalla debe encenderse al menos una vez al mes durante más de 2 horas.
In addition to the installed LED display screens should pay attention to waterproof and moisture-proof in the rainy season, the engineering contractors and distributors also need to understand the treatment methods of the LED display screens entering the warehouse.
