Electromagnetic shielding film, plasma display panel filter using the electromagnetic shielding film, plasma display panel device including the electromagnetic shielding film, and method of manufacturing the electromagnetic shielding film
View Patent ↗Provided are an electromagnetic shielding film capable of improving brightness, a plasma display panel (PDP) filter using the electromagnetic shielding film, a PDP device including the electromagnetic shielding film, and a method of manufacturing the electromagnetic shielding film. The electromagnetic shielding film includes a transparent substrate, an electromagnetic shielding film pattern which is formed on the transparent substrate and whose face opposite to the transparent substrate is blackened, and a black conductive layer pattern which is formed on the electromagnetic shielding film pattern. The method includes (a) forming a non-conductive layer on a conductive substrate, (b) forming a non-conductive layer pattern by patterning the non-conductive layer, (c) forming a black conductive layer pattern on the conductive substrate exposed by the non-conductive layer pattern, (d) forming an electromagnetic shielding film pattern on the black conductive layer pattern, (e) oxidizing the electromagnetic shielding film pattern to blacken the same, and (f) separating the black conductive layer pattern and the electromagnetic shielding film pattern from the conductive substrate using a transparent substrate on a face of which an adhesive is formed.
1. An electromagnetic shielding film, comprising:
a transparent substrate;
an electromagnetic shielding film pattern formed above the transparent substrate, wherein a face of the electromagnetic shielding film pattern facing the transparent substrate is blackened;
a black conductive layer pattern formed above the electromagnetic shielding film pattern;
a first seed layer formed on one side of the black conductive layer pattern; and
a second seed layer formed on the other side of the black conductive layer pattern and is on the electromagnetic shielding film pattern.
2. The electromagnetic shielding film of claim 1 , wherein the black conductive layer pattern includes black nickel.
3. The electromagnetic shielding film of claim 1 , wherein the electromagnetic shielding film pattern includes copper.
4. The electromagnetic shielding film of claim 1 , wherein the first seed layer and the second seed layer are made of nickel.
5. The electromagnetic shielding film of claim 1 , wherein in the electromagnetic shielding film pattern, sidewalls are blackened.
6. A plasma display panel (PDP) filter including the electromagnetic shielding film of claim 1 .
7. A plasma display panel (PDP) device including the PDP filter of claim 6 .
