| Abstract: | The LED display screens have been used in many areas, such as traffic, negotiable securities, telecommunication, advertisement drumbeating and so on. However, the EMI problems which have been brought about should also be paid more attention to. By introducing the working principle of the video LED display screen and analyzing the main EMI factor of the video LED display screen, some effective measures for rectifying above are put forward and some successful debug examples are enumerated. |
