Abstract:
A damping and muffling structure for EL device, comprising a transparent substrate, a transparent front electrode layer, a lighting layer, an inducing layer and a back electrode layer which are sequentially overlaid on the substrate, the lighting layer, the inducing layer and the back electrode layer being enclosed by a packaging layer, a bus bar being disposed on one side of the front electrode layer, the bus bar and the back electrode layer being connected to a driving circuit which via AC voltage drives the lighting layer to emit light, a damper being disposed on one face of the packaging layer distal from the front electrode layer, an insulating structure being disposed between the damper and the back electrode layer, the damper being made of de-static material, the damper having an area sufficient for covering the bus bar of the front electrode layer, the damper being connected to a grounding pole of the driving circuit.
