Abstract

In this papaer, 7-segment was implemented using AC powder EL. ZnS:Cu and $BaTiO_3$ was used as a phosphor and dielectric respectively. The preparation of phosphor and dielectic layer was performed with screen printing. The implemented system of 7-segment was divided as following; EL display. driving circuit. software for driving. The properties of fabricated devices was measured with EL spectrum. brightness and J-V.
