Generally, the LED display screen we see is fixed, and the position is rarely changed after installation. However, there are also some LED displays that need to be replaced frequently, such as LED rental screens, caravan LED displays, etc. Led rental screen is mainly used for leasing to the project contractor, such as stage performance, activity performance, tour performance, etc; The caravan LED display screen is mainly used for mobile publicity, temporary performance projects, etc. the characteristics of such LED display screens are that they need to be moved frequently to meet the requirements of different customers, different projects or different venues.
4). The power supply of the display screen shall have the function of power sharing backup. Current sharing backup mainly refers to that when one or several power supplies in a large screen fail, the nearby power supplies will automatically supply power to the display screen, so that the entire LED display screen will not be black due to the failure of some power supplies. This function is extremely important for the LED display screen leased by Wumei. If the LED display screen used for the stage matching with the background performance is black due to the failure of a certain power supply, it will affect the effect of the whole program, give the audience a bad experience and leave a bad impression. The current sharing backup function of the power supply solves this problem well.
