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: 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. 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 staff negligence or other reasons, a display signal input line in the middle of the large screen becomes loose, in a conventional control scheme, from the loose box to the end of the signal cascade, all displays There will be no signal. If a hot backup solution is added to the control system, the hot backup function will be activated at the moment when the signal line is loosened, and the display screen can still work normally without any impact on the live broadcast scene.
