How to improve the stability of the stage LED rental screen

In recent years, LED displays have been used more and more frequently in large-scale events such as advertising, performances, parties, press releases, and weddings. Moreover, with the development of technology and changes in demand, higher requirements for LED rental screen functions have also been proposed. For example, in order to achieve various better stage display effects, it is necessary to frequently change the display splicing shape, which is not only convenient to install and debug, but also has high stability. So how to improve the stability of the rental LED stage screen? Puxun Electronics will make detailed explanations from three aspects: material selection, system control scheme and real-time monitoring of display working status.

We all know that the most important factor in determining the quality of LED display is its raw materials; like LED lights, driver ICs, power supplies, power signal connectors, etc. Our requirements for material selection are: internationally renowned brands, which are required to be tested in accordance with industry standards and various protection functions. For example, switching power supply selection requirements: there is overheat protection, AC input should support wide voltage, anti-surge. The DC output should have overvoltage and overcurrent protection. The structural design ensures a good heat dissipation method and a fast splicing method while ensuring the appearance and fashion of the box.

Because of the particularity of the leasing industry, it is extremely demanding for its stability at work. Therefore, each link of the system control scheme has a hot backup function, including a video transmitting and receiving device, a signal transmission cable, and the like. It can ensure that when an unexpected situation occurs in a certain part of the system, the system can automatically diagnose and switch to the standby device at an extremely fast speed. The entire switching process will not affect the display effect of the scene. For example, in order to meet the needs of the stage scene, the LED rental screen needs to be moved and stitched at the live broadcast site. If a display signal input line in the middle of a large screen is loosened due to staff negligence or other reasons, in the conventional control scheme, from the occurrence of the loose box to the end of the signal cascade, all the displays 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 leased LED stage screen can still work normally without any impact on the live broadcast site.

The working status of the display can be monitored in real time by computer, including temperature, humidity, voltage, smoke, working status of the cooling fan, and so on. Automatic adjustment of various conditions can occur, providing location and alarms for anomalies. For example, when a cabinet has a relatively high internal temperature due to environmental or other factors, the power inside the cabinet may be over-temperature protected at any time without timely processing. If the display is monitored in this situation, the system will reduce the internal temperature of the display by intelligently adjusting the operating state of the display. When the intelligent adjustment can't lower the temperature to the set target, the system will alarm by the staff setting mode, and provide the abnormal box position to notify the staff to deal with it in time. Ensure the normal working state of the display and safe use.

In short, to improve the stability of the stage LED rental display should be considered from the material selection, hardware design, system control program and so on.
