Electrical Characterization and Modeling of ZnS:Mn ACTFEL Devices with VariousPulse Waveforms

摘要

The electrical response of ZnS:Mn ac thin-film electroluminescent (ACTFEL)devices is studied as characteristics of the driving waveform are systematically varied. Specifically, the conduction turn-on voltage, phosphor conduction charge, and relaxation charge are measured as a function of variations in the maximum amplitude, pulse width, and rise/fall time of the driving waveform. These experimental trends are found to be in excellent agreement with SPICE simulation when a refined equivalent circuit model for the ACTFEL device is employed. Electroluminescence, ACTFEL, SPICE.
