摘要:
A method for forming flat display panel phosphor dots is disclosed wherein a conventional printing method or procedure is used in combination with an optical method.The paste film containing the phosphor, photoresist and powdered glass is coated on the surface of the dielectric layer, e.g. lead glass layer by means of the printing method. The paste layer is irradiated by a ultraviolet light through a mask, and after the development of the paste layer has been completed, the remaining hardened portions of the paste layer are subjected to a heat treatment. In this way, phosphor dots having a desired shape can be formed very firmly and very exactly at certain predetermined portions on said dielectric layer.
