| Abstract(in English) | The EL performance of high frequency driven oxide phosphor TFEL devices using a thick BaTiO_3 ceramic sheet insulator have been demonstrated. The EL characteristics such as luminance, threshold voltage and luminance increase in relation to applied voltage under sinusoidal wave voltage driving were considerably improved by increasing frequency from 60Hz to 10kHz, whereas they remained relatively unchanged when driven by pulse wave voltages. The improvement of L-V characteristics can be explained by considering the dielectric relaxation time of the individual emitting layer and insulating layer. Luminaces above 1000 cd / m^2 for green emission was obtained in Ga_2O_3 : Mn and ZnGa_2O_4 : Mn TFEL devices, driven with a voltage below 120V at 10kHz. |
