Damping and muffling structure for EL cell

Abstract

A damping and muffling structure for EL cell includes a transparent substrate, a front electrode layer, a lighting layer, an inducing layer, a back electrode layer and an insulating layer. The front electrode layer, lighting layer, inducing layer, back electrode layer and insulating layer are sequentially overlaid on the substrate. A conductive layer is laid between the lighting layer and the inducing layer. The conductive layer is connected to a grounding electrode of a driving circuit, whereby the conductive layer can quickly remove the charge accumulating on the inducing layer so as to minify or even eliminate the vibration and noise of the EL cell.
