The LED stage screen is often accompanied by a feast. Imagine that a concert or party will be halfway through, and the screen will not be too bright or flashing will have much impact on the event. Therefore, it is especially important to improve the stability of the LED stage screen. Specifically, the following three points can improve the stability of the LED stage screen.
Choose materials carefully
LED display materials include LED lights, driver ICs, power supplies, power signal connectors, etc. These are the core elements that determine the quality of LED displays.
Therefore, the 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.
Technical requirements for system control schemes
Because of the particularity of the stage LED display, it is extremely demanding for stability during operation. 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 stage LED display needs to be moved and stitched on the live scene. 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 scheme is added to the control system, the hot backup function is activated at the moment when the signal line is loose, and the stage LED display can still work normally, and will not bring any influence to the live broadcast site.
Real-time monitoring of working status
The working status of the stage LED display can be monitored in real time by computer, including temperature, humidity, voltage, smoke, cooling fan working status 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.
