Let's analyze this black screen event from a professional point of view. Why does the LED display suddenly black? On how to make a black screen LED display. The black screen phenomenon may be caused by various reasons, such as poor signal line or power line contact, signal receiving card failure, display power failure, power distribution system failure, etc. Any problem may cause a black screen phenomenon. First, it is necessary to ensure the quality and reliability of any component of the LED display body, and it is not possible to reduce the quality in order to price. Connectors, receiver cards, power supplies, etc. must be of high quality. Second, system backup, including software backup and hardware backup, automatically switch to the backup line when the line is bad. Third, the control system has the data double backup function, synchronous asynchronous free switching, and can work offline after running, to ensure that the LED display will never be black after the computer failure. Therefore, LED display reliability and system backup in important scenarios are particularly important. When choosing a LED display manufacturer, you must choose a big brand, and the quality is guaranteed. According to the analysis of LED display industry insiders: "The specific reason for the display failure is not good. Only the professional technicians at the scene know the actual situation.
