With the rapid development of science and technology today, LED display screens are frequently used in large-scale events such as advertisements, performances, parties, press releases, and the stability of the display screen plays a vital role in the whole process, especially at the performance site. Active rental series. In order to achieve various display effects, it is necessary to frequently change the splicing shape of the display screen. The requirements for the display screen are not only convenient for installation and debugging, but also extremely stable. So how to improve the stability of the rental LED stage screen? The following explains from three aspects: 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 screen are LED lights, driver ICs, power supplies, power signal connectors and excellent structural design. Our requirements for material selection are: internationally well-known brands, related tests that are higher than the industry standard requirements, and requirements for various protection functions. For example, switching power supply selection requirements: overheat protection, AC input must support wide voltage and 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 that the cabinet is beautiful and fashionable.
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 an extremely fast speed When the standby device works, the whole switching process will not affect the display effect on site. For example, in order to meet the needs of the stage scene, the display screen needs to be mobile spliced in the live broadcast scene. If due to the negligence of the staff or other reasons, a certain display signal input line in the middle of the large screen becomes loose, in the conventional control scheme, from the loose box body to the end of the signal cascade, all the display screens There will be no signal. If a hot backup solution is added to the control system, the hot backup function will be activated when the signal line is loosened, and the display can still work normally without any impact on the live broadcast 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. For example: when a cabinet has a relatively high internal temperature due to the environment or other factors, the power supply inside the cabinet will be protected from over-temperature 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 position of the abnormal box, and notify the staff to deal with it in time. Ensure the normal working condition of the display screen.
In short, to improve the stability of the display screen must be comprehensively considered from various aspects such as material selection, hardware design, system control scheme and so on. An experienced and powerful RD team is required.
