Method for forming phosphor layers of plasma display panel and apparatus therefor

摘要

To form a plurality of stripe-like phosphor layers on a surface of a substrate in forming a plasma display panel, the surface having a plurality of parallel ribs disposed thereon and grooves defined between pairs of adjacent ribs, the following steps are carried out: providing a filamentary body formed from a phosphor paste composed of a phosphor substance and a first synthetic resin; placing a moulded filamentary body in each groove; filling the grooves with a solvent optionally containing a second synthetic resin compatible with the first synthetic resin; and conducting a sintering treatment of the substrate to form the phosphor layers in the grooves. An apparatus for this purpose has a mounting base (51) for mounting thereon a substrate (21) having a plurality of parallel ribs (r) disposed thereon and grooves (g) defined between pairs of adjacent ribs, and a supplier (53) for supplying a filamentary body (54) into the grooves, the filamentary body being made of a phosphor substance and a synthetic resin.
