From the perspective of LED large screen use, LED large screen full-color screen is the mainstream in the future. Because of the high brightness and full color, it can work all day, but the price is high.
From the application point of view, there is a reason for the existence of products that meet the needs of users. Due to its low price, maturity and stability, dual-primary color displays occupy a large market when displaying text and colors without blue.
The orientation and distance of the outdoor screen play a decisive role in the price. The further the distance, the larger the pixels and the brighter the brightness. Northeast facing monitors are much cheaper than southwest facing monitors.
The screen and the connection between the screen and the building must be strictly waterproof and leak-proof. The filter screen should have good drainage measures, and once there is accumulated water, it can be discharged smoothly.
Install lightning protection devices on large LED screens and buildings. The main body and shell of the display screen are well grounded, and the grounding resistance is less than 3, which can discharge the large current caused by lightning in time.
Install ventilation equipment to cool down, so that the internal temperature of the screen is between -10~40. It is also possible to install an axial fan on the rear and top of the screen to dissipate heat.
Use industrial-grade integrated circuit chips with a working temperature between -40-80 to prevent the display from being unable to start when the temperature is too low in winter.
