Abstract

Electroluminescence is occurred by electric filed located in the phosphor. Until now most of EL researched have been studied the characteristics of devices that drive over 400Hz and commercialized, but in Problems of life time, natural aging increased with behavior of high frequency in the phosphor. In this paper, we investigated the luminescence characteristics were driven by low frequency($0{\sim}100Hz$). Moreover, we Presented the improvement way in the method device production and drive power as measurement at commercial frequency(60Hz).
