According to market surveys and user feedback, LED displays generally begin to expose problems within half a year to one year after they are newly set up in actual use environments, and the status of the display becomes unstable, among which frequent minor problems include lamp bead damage/ The brightness attenuation of the bright spots or the whole unit is inconsistent (does not affect the use but affects the appearance), the big problem is that the direct screen and black screen need to stop maintenance.
Failure maintenance of outdoor LED display screens usually cannot be completed by ordinary equipment maintenance personnel. Generally speaking, manufacturers need to arrange engineers for maintenance, and the maintenance process is also very troublesome. The damaged target display unit needs to be disassembled for maintenance or directly replaced (usually maintenance is preferred, and the new display unit is directly replaced. The brightness of the old and new display units is attenuated. The curve is inconsistent, and it is easy to form the phenomenon of Yin-Yang screen with different brightness), which is very time-consuming.
