How much do you know about the hardware of outdoor LED Screen
Outdoor LED display lamp beads and chip quality. When purchasing these devices, we should see clearly that the lamp bead products must have the characteristics of good stability, small dispersion, small attenuation range and strong pressure resistance. In addition, they have good light distribution effect and adapt to many external outdoor conditions such as strong temperature difference.
Outdoor LED screen switching power supply, because the design of switching power supply is more safe, so the power supply that has passed the safety certification must be used here before the connector can be used, so as to better ensure that the system has good electrical connection performance in the high-temperature and humid environment, so as to make the display screen run well.
In terms of outdoor LED display circuit board, generally speaking, the engineers of Outdoor LED screen manufacturers will be equipped with flame-retardant epoxy plate, because in this way, the wiring can be standardized and 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.
Outdoor LED screen is different from other outdoor display products. If it is not handled well, there is also conflict between switching on and off. Here, we should pay attention to starting the screen first and then turning it on. However, when closing the screen, we should first switch the screen on and off and then turn it off. We should pay attention to that the time interval between switching the screen on and off is greater than ten minutes. Because the impulse current of the system is the largest at this time, it is easy to damage the display screen.
The power cord of the computer control part of the outdoor LED display screen shall not be connected reversely, and shall be inserted in strict accordance with the original position. If the connection is reversed, test whether it is charged after the connection is completed. Because the position and length of communication line and flat connecting line cannot be changed at will. Therefore, we should conduct power on test repeatedly and find problems in time.
