Claims
- 1. An apparatus for forming a plurality of striped phosphor layers on a surface of a substrate of a plasma display panel, the surface having a plurality of parallel ribs disposed thereon and grooves, each groove defined between two adjacent ribs, comprising:a mounting base mounting the substrate thereon; a supplier supplying a filament article into each groove, the filament article being made of a phosphor and a synthetic resin; and a fixing tool fixing an end of the filament article when the filament article is supplied.
- 2. The apparatus of claim 1, wherein the supplier comprises a rotatable cylinder having a circumferential channel thereon, the supplier rotating the cylinder on the substrate to feed the filament article to the corresponding groove through the channel of the cylinder.
- 3. The apparatus of claim 1, wherein the filament article being made by mixing a phosphor and a synthetic resin in a solvent, molding the resultant mixture into a filament shape and evaporating the solvent.
- 4. The apparatus of claim 1,wherein the filament article is made by: providing an ejecting nozzle with a pre determined inner diameter and a rotating endless supporter, ejecting a phosphor paste comprising a phosphor substance and a synthetic resin from the ejecting nozzle into a surface of the rotating endless supporter to form a striped coated line, heat-treating the coated line on the surface, and continuously peeling the resulting filament article from the surface.
- 5. An apparatus for forming a plurality of striped phosphor layers on a surface of a substrate of a plasma display panel, the surface having a plurality of parallel ribs disposed thereon and grooves, each groove defined between two adjacent ribs, comprising:a mounting base mounting the substrate thereon; and a supplier supplying a filament article into each groove, the filament article being made of a phosphor and a synthetic resin, wherein the supplier comprises: a supporter supporting both ends of one of the filament articles in parallel to a corresponding groove above the substrate, a mover moving the mounting base perpendicularly to the corresponding groove to align the filament article with the corresponding groove, and a driver lowering the supporter to place the filament article in the corresponding groove.
