Usually, the LED display screen we see is fixed, and the position is rarely changed after installation. However, there are some LED display screens that need to be changed frequently, such as LED rental screen, caravan LED display screen, 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 characteristic of this kind of LED display screen is that it needs to be moved frequently to meet the requirements of different customers, different projects or different venues.
So, what characteristics should these movable LED displays have?
1) For the LED display screen that needs to be moved frequently, a single box cannot be too heavy, which is mainly to facilitate box splicing, handling, disassembly and other operations. If the box is too heavy, the handling and disassembly will be very slow and the efficiency is not high.
2) The waterproof and dustproof grade shall be at least IP65 or above, mainly because many performance projects are completed outdoors, and rain and dust are inevitable outdoors. The protection grade above IP65 can prevent rain or dust from entering the display screen, so as to effectively protect the LED display screen.
3) The power box of the display screen shall be easy to disassemble and the power supply shall be easy to replace. Because the LED display screen, which is often disassembled, installed and debugged, has a certain loss on the power supply, relatively speaking, the failure rate of the power supply will be higher than that of other components. Making the structure of the power box easy to replace is conducive to maintaining the long-term and stable operation of the whole display screen.
4) . the power supply of the display screen needs to have the function of power current 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 whole LED display screen will not be black due to the failure of several power supplies. This function is very important for the LED display screen of digital dance beauty rental, because if the LED display screen used for matching the background performance on the stage is black due to the failure of a power supply, it will affect the effect of the whole program, bring a bad experience to the audience and leave a bad image, and the current sharing backup function of the power supply solves this problem well
