A method for coating a phosphor on a flat display using electrophoretic deposition (EPD) and lithography is provided. In the method, an adhesive strength can be enhanced without passing through a high-temperature thermal treatment process as a post-process. Phosphor powders are coated on a substrate by a field emission display (FED) and then a ultraviolet (UV) curable layer is coated. Then, an adhesive strength of the phosphor can be greatly enhanced through UV irradiation, in comparison with a post-process such as a thermal treatment process. Also, the UV curable layer can be lithographically etched by the UV light, and thus the phosphor can be coated by a predetermined pattern, to then be applied to a next-generation display such as a FED or PDP as an optimal method for full color realization.

Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.

The present invention intends to provide a manufacturing method for a PDP that can continuously apply phosphor ink for a long time and can accurately and evenly produce phosphor layers even when the cell construction is very fine. To do so, phosphor ink is continuously expelled from a nozzle while the nozzle moves relative to channels between partition walls formed on a plate so as to scan and apply phosphor ink to the channels. While doing so the path taken by the nozzle within each channel between a pair of partition walls is adjusted based on position information for the channel. When phosphor particles is successively applied to a plurality of channels, phosphor ink is continuously expelled from the nozzle even when the nozzle is positioned away from the channels. The phosphor ink is composed of: phosphor particles that have an average particle diameter of 0.5 to 5 mum; a mixed solvent in which materials selected from a group consisting of terpineol, butyl carbitol acetate, butyl carbitol, pentandiol, and limonene are mixed; and a binder that is an ethylene group polymer or ethyl cellulose containing at least 49% of ethoxy group (-OC2H5) cellulose molecules.
