LED户外全彩屏的MTBF和可靠性

MTBF and Reliability of LED Outdoor Full-color Display

介绍了LED户外全彩屏的平均无故障时间(MTBF)及可靠性,着重讨论了提高全彩屏可靠性的几个问题。提出建立合理的可靠性模型,加强可靠性试验,建立故障分析与纠正措施系统(FRACAS)和确定平均修复时间(MTTR)。

The article introduced MTBF(Mean Time Between Failures) and reliability of LED outdoor fullcolor display, discussed some problems of improving fullcolor display′s reliability.It demonstrated that to build up proper reliability model, enhance reliability test, establish FRACAS(Fail ReportAnalysis Correct Analysis System) and MTTR(Mean Time to Repair) are effective ways to improve the reliability.
