With the rapid development of science and technology today, LED rental screens are frequently used in large-scale events such as exhibitions, commercial performances, weddings, conferences, and the stability of the display screen plays a vital role in the whole process, so how to improve LED rental How about the stability of the screen? The following explains from three aspects: material selection, system control scheme, and real-time monitoring of the working status of the screen.
The key materials that determine the stability of the display screen are LED lights, driver ICs, power supplies, power signal connectors and excellent structural design. For example, switching power supply selection requirements: overheating protection, AC input must support wide voltage, anti-surge. The DC output must be protected against overvoltage and overcurrent. The structural design must ensure good heat dissipation and fast splicing while ensuring the appearance and fashion of the cabinet.
Each link of the system control scheme has a hot backup function, including video sending and receiving equipment, signal transmission cables, etc., which can ensure that when an unexpected condition occurs in a certain link of the system, the system can automatically diagnose and switch at a very fast speed When the standby device is working, the whole switching process will not affect the display effect of the scene.
The working status of the display screen can be monitored in real time with a computer, including temperature, humidity, voltage, smoke, working status of the cooling fan, and so on. It can automatically adjust and deal with various situations that occur, and provide locations and alarms for abnormalities. When a cabinet has a relatively high internal temperature due to the environment or other factors, the power supply inside the cabinet will have over-temperature protection at any time if it is not handled in time. If monitoring the working status of the display screen under this condition, the system will reduce the internal temperature of the display screen by intelligently adjusting the working state of the display screen. When the intelligent adjustment cannot reduce the temperature to the set target, the system will alarm through the staff setting method, and provide the location of the abnormal box, and notify the staff to deal with it in time. Ensure the normal working state of the display screen.
