In the rapid development of science and technology today, LED display in the advertising, performances, parties, press releases and other large activities frequently used, and the stability of the display in the whole process plays a vital role, especially the performance site Activities of the rental series. In order to achieve a variety of display, you need to often change the display splicing modeling, the requirements of the display not only to facilitate the installation and debugging, but also a very high stability. So how to improve the stability of the rental LED stage screen? The following from the material selection, system control program, display working status real-time monitoring of three aspects to illustrate.
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, to higher than the industry standard requirements for testing, as well as a variety of protection requirements. Such as switching power supply selection requirements: overheat protection, AC input to support wide voltage, anti-surge. DC output should be over-voltage, over-current protection. Structural design to ensure that the box beautiful fashion at the same time, but also to ensure a good way to heat and fast stitching.
Each part of the system control program has a hot backup function, including video transmission, receiving equipment, signal transmission cable, etc., it can ensure that the system in a certain part of the accident situation, the system can automatically diagnose and switch at an extremely fast speed To the standby equipment work, the entire switching process will not have an impact on the display of the scene. For example: to meet the needs of the stage scene, the display needs to live on the live scene stitching modeling. If a display screen signal input line is loose in the middle of a large screen due to staff negligence or other reasons, in the conventional control scheme, from the beginning of the loose box to the end of the signal cascade, all displays Will have no signal. If the control system to join the hot backup program, the signal line in the moment, the hot backup function is activated, the display can still work properly, will not bring any impact to the live scene.
