| 摘 要： | 为了解决LED显示屏的条状缺陷问题，通过对电路结构进行观察分析，并进行实验测试，发现条状缺陷通常是由于串联模组电流输入端的片个LED模块出现故障。从而导致LED显示屏出现条状缺陷，因此．LED显示屏出现条状缺陷，其原刚通常是该条状模组的电流输入端的首个LED出现故障，如断路问题：

| Abstract: | In order to solve the problem of strip defects of LED display,through the observation and analysis of the circuit structure,and testing,found that strip defects are usually the result of the first LED module se- ries module current input failure,resulting in LED screen appear strip defects.Therefore,LED displays a strip defects,the cause is usually the first LED current input end of the strip-shaped module failures,such as broken circuit problem. |
