Rental LED stage screen how to improve stability

LED display screens are frequently used in large-scale events such as advertisements, performances, parties, and news releases, and the stability of the display screen plays a crucial role in the entire process, especially the rental series of live performances. In order to achieve various display effects, it is necessary to change the splicing shape of the display screen frequently. The requirements for the display screen are not only convenient installation and debugging, but also extremely high stability. So how to improve the stability of rental LED stage screen? The following three aspects are explained in terms of material selection, system control scheme, and real-time monitoring of the working status of the display screen.

The key materials that determine the stability of the display are LED lights, driver ICs, power supplies, power signal connectors and excellent structural design. Our requirements for material selection are: internationally renowned brands, relevant tests that are higher than industry standards, and requirements for various protection functions. For example, switching power supply selection requirements: with overheat protection, AC input should support wide voltage, anti-surge. The DC output must have overvoltage and overcurrent protection. The structural design not only guarantees the appearance and fashion of the box, but also ensures a good heat dissipation method and a fast splicing method.

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 situation occurs in a certain link of the system, the system can automatically diagnose and switch at a very fast speed. When the standby device works, the entire switching process will not affect the on-site display effect. For example, in order to meet the needs of the stage scene, the display screen needs to be moved and spliced ​​in the live broadcast scene. If the signal input line of a display screen in the middle of the large screen is loose due to the negligence of the staff or other reasons, in the conventional control scheme, from the loose box to the end of the signal cascade, all display There will be no signal. If a hot backup solution is added to the control system, the hot backup function is activated at the moment when the signal line is loose, and the display screen can still work normally without any impact on the live broadcast site.

The working status of the LED full-color display can be monitored in real time with a computer, including temperature, humidity, voltage, smoke, the working status of the cooling fan, etc. It can automatically adjust and process various situations that occur, and provide location and alarm for abnormality. For example, when a box has a high temperature due to the environment or other factors, the power supply inside the box will be protected against over-temperature at any time if it is not dealt with in time. If the working status of the display screen is monitored under this condition, the system will reduce the internal temperature of the display screen by intelligently adjusting the working status of the display screen. When the intelligent adjustment cannot reduce the temperature to the set target, the system will give an alarm through the setting method of the staff, and provide the position of the abnormal box to notify the staff to deal with it in time. Ensure the normal working state of the display screen.

In short, to improve the stability of the rental LED stage screen, we should comprehensively consider all aspects such as material selection, hardware design, system control scheme and so on. An experienced and powerful R&D team is required.
