In the outdoor LED large screen environment, the quality requirements are higher, and there are many factors to be considered.
1. From the perspective of the application of LED large screen, 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. 2. From an application point of view, there is a reason for a product that meets user needs. Due to its cheap price, maturity and stability, the dual-primary color display has a large market in terms of no blue characters and color display. 3. The direction and distance of the outdoor screen play a decisive role in the price. The farther away, the larger the pixel and the brighter it is. Displays in the northeast are much less expensive than those in the southwest. 4. The joint between the screen and the building must be strictly waterproof and leak-proof. The filter should adopt good drainage measures, and once there is accumulated water, it can be discharged smoothly. 5. Install lightning protection devices on LED displays and buildings. The display body and the casing are well grounded, the grounding resistance is less than 3, and the large current caused by lightning can be discharged in time. 6. Install ventilation equipment for cooling to ensure that the internal temperature of the screen is between -10-40. A fan can also be installed at the rear of the screen to dissipate heat. 7. Select an industrial-grade integrated circuit chip with a working temperature of -40-80 to prevent the screen from not starting when the temperature is too low in winter.
