Abstract

The inorganic powder EL lamp was made by screen printing technique with a phosphor ink and a dielectric ink. The thickness of a phosphor ink layer and a dielectric ink layer is $35{\mu}m$ and $54{\mu}m$ respectively. A increasing ratio of the luminance of inorganic powder EL lamp to be a 1P1PD-phosphor ink layer in which increased voltage at constant frequency is higher 12% than when increased frequency at constant voltage. It is higher 57% than when increased frequency at constant voltage that the rate of increase of the luminance of inorganic powder EL lamp to be a 2PD-phosphor ink layer in which increased voltage at constant frequency. Finally, when increased voltage at constant frequency, a increasing ratio of the luminance of inorganic powder EL lamp to be a 2PD-phosphor ink layer is higher about 40% than that to be a 1P1PD-phosphor ink layer.
