LED display in the use of a variety of reasons lead to increased current, then if you do not take protective measures, increase the current over a certain period of time and amplitude after the LED display will be damaged. So let's take a closer look at the specific cause of LED damage.
LED display damage to the main reasons are:
1. Sudden increase in voltage.
2. One of the components or printed wiring or other short-circuit and the formation of LED power supply circuit of the local short circuit, so that the local voltage increases.
3.LED display because of their own quality damage caused by a short circuit, then its original voltage drop on the increase to other LED.
4. The internal temperature is too high, so that the characteristics of LED deterioration.
5. Internal water intake.
6. Installation time is not doing anti-static work, LED internal has been hurt by static electricity. Although the application of the normal voltage and current values, but also easily lead to damage to the LED.
