光固化三维立体打印用液晶显示屏寿命测评试验研究

Research on TFT-LCD Life Test for 3D Printing

以典型光固化三维立体打印用液晶显示屏产品为研究对象,通过客户端不良信息收集,识别影响整机光固化功能组件液晶显示屏关键特性并确定其失效阈值。利用基于产品性能退化的寿命评价方法进行实验设计与实施,通过分布检验、Weibull概率纸法、模型回归和拟合找到该产品的可靠度、累计失效概率、故障率,为技术人员在可靠性预计与维保方面提供技术指导。

Typical light-curing 3D printing LCD products were taken as the research object.Through the collection of bad information from the clients,the key characteristics of LCD that could affect the light curing function of the whole machine were identified and the failure threshold was determined.The life evaluation method was used based on product performance degradation to carry out the experimental design and implementation.Through the distribution test,Weibull probability paper method,model regression and fitting,the reliability,cumulative failure probability,and failure rate of the product could be found,which was expected to provide technical guidance on maintenance.
