Paper Abstract

While considerable work has been done in developing monochrome AC thin-film electro-luminescent (TFEL) displays, primarily using yellow-emitting ZnS:Mn, recent work with green-emitting ZnS:TbF3 offers a second bright color. There is also growing need for and interest in an EL panel incorporating more than one color for visual pattern contrast. Since both of these phosphors and the insulators are transparent thin films, a multiple stack construction was selected, using transparent electrodes. Such panels with rudimentary fixed patterns were successfully fabricated and demonstrated as a feasibility study of the stacked construction and evaluation of the color compatibility of these two phosphors in a single display.
