Abstract:In order to estimate the lifetime of Vacuum Fluorescent Display (VFD) in a short time, four constant stress accelerated life tests (CSALT) are carried out with its filament temperature increased. The lifetime prediction software for VFD is developed by a hybrid programming method of VB and MATLAB based on COM component, and the life estimation is achieved. The results indicate that the test design scheme and lifetime prediction method are correct and feasible. The accurate accelerated parameter calculated by this software makes it possible to predict the VFD lifetime rapidly.
