The quality of lamp beads and chips of outdoor LED display screens. When purchasing these devices, we must look at the lamp bead products. They must have the characteristics of good stability, small dispersion, small attenuation, and strong voltage resistance. The light effect is good, and it is suitable for many external outdoor conditions such as strong temperature difference.
Outdoor LED display switching power supply, because the design of switching power supply is more safe, so here you must use a power supply that has passed safety certification before you can connect plug-ins, so as to better ensure that the system has good performance in high temperature and humid environments. Electrical connection performance, so that the display screen works well.
In terms of outdoor LED display circuit boards, generally speaking, the engineers of LED display manufacturers will be equipped with flame-retardant epoxy boards, because in this way, the wiring can be standardized, which can well meet the electromagnetic compatibility and circuit stability. Using reliable supporting materials and professional R&D technology as much as possible can make the screen run more stably.
The outdoor LED display is different from other outdoor display products. What we need to pay attention to here is to turn on the screen first and then turn on the screen. However, when the screen is turned off, the screen should be turned on and off first, and then the screen should be turned off. Note that the interval between turning the screen on and off is greater than ten minutes. Because the inrush current of the system is the largest at this time, it is easy to cause damage to the display screen.
The power cord of the computer control part of the outdoor LED display cannot be reversed, and it should be plugged in strictly according to the original position. If the connection is reversed, after the connection is completed, test whether it is live. Because the position and length of communication lines and flat connecting lines cannot be changed at will. Therefore, we should repeat the power-on test and find the problem in time.
