Abstract
Disclosed herein is a PDP filter having a laminated structure of a transparent conductive film type electromagnetic wave-shielding layer and one or more other functional layers, in which at least two edge portions of the surface of the transparent conductive film type electromagnetic wave-shielding layer, which is in contact with the functional layer, are not exposed outside the laminated structure of the PDP filter.
Claims31
A PDP (Plasma Display Panel) filter, having a laminated structure comprising a transparent conductive film type electromagnetic wave-shielding layer and one or more other functional layers, in which none of four edge portions of a surface of the transparent conductive film type electromagnetic wave-shielding layer, which is in contact with the functional layer, are exposed outside the laminated structure of the PDP filter,
- wherein a width of the functional layer is equal to a corresponding width of the transparent conductive film type electromagnetic wave-shielding layer, and the transparent conductive film type electromagnetic wave-shielding layer is not electrically grounded.
A method of manufacturing a PDP (Plasma Display Panel) filter, comprising forming one or more other functional layers on an upper surface, a lower surface or both surfaces of a transparent conductive film type electromagnetic wave-shielding layer using a coating process, in which the coating process is performed on an entire surface of the coating surface of a transparent conductive film type electromagnetic wave-shielding film so as not to expose all edge portions of the coating surface of the transparent conductive film type electromagnetic wave-shielding film,
- wherein a width of the functional layer is equal to a corresponding width of the transparent conductive film type electromagnetic wave-shielding layer, and the transparent conductive film type electromagnetic wave-shielding layer is not electrically grounded.
A PDP (Plasma Display Panel) filter, comprising a transparent substrate, a transparent conductive film type electromagnetic wave-shielding layer including high-refractive transparent thin film layers and metal thin film layers that are alternately laminated on the transparent substrate and a high-refractive transparent thin film layer provided on an uppermost surface of the alternately laminated layers, and a low-refractive transparent thin film layer formed on the uppermost high-refractive transparent thin film layer, in which none of four edge portions of a surface of the transparent conductive film type electromagnetic wave-shielding layer, which is in contact with the low-refractive transparent thin film layer, are exposed,
- wherein a width of the functional layer is equal to a corresponding width of the transparent conductive film type electromagnetic wave-shielding layer and the transparent conductive film type electromagnetic wave-shielding layer is not electrically grounded.
A method of manufacturing a PDP (Plasma Display Panel) filter, comprising:
- alternately laminating high-refractive transparent thin film layers and metal thin film layers on a transparent substrate, and providing a high-refractive transparent thin film layer on an uppermost surface of the alternately laminated layers, thus forming a transparent conductive film type electromagnetic wave-shielding layer;
- and forming a low-refractive transparent thin film layer on the uppermost high-refractive transparent thin layer film layer, in which none of four edge portions of a surface of the transparent conductive film type electromagnetic wave-shielding layer, which is in contact with the low-refractive transparent thin film layer, are exposed,
- wherein a width of the functional layer is equal to a corresponding width of the transparent conductive film type electromagnetic wave-shielding layer, and the transparent conductive film type electromagnetic wave-shielding layer is not electrically grounded.
