Abstract: An improved distribution system and method of operating the same are provided. In one embodiment, the distribution system includes a plate for loading a plurality of substrates thereon, a first transfer assembly for transferring the substrates from the plate to a conveyer, and a distribution assembly for distributing the substrates transferred by the conveyer to a first testing assembly and a second testing assembly. The distribution assembly includes a first sub-conveyer and a second sub-conveyer, and the outlet of one of the first sub-conveyer and the second sub-conveyer corresponds to the inlet of one of the first testing assembly and the second testing assembly.

Abstract: The present invention relates to a phosphor for a plasma display panel and a method for producing the same. The phosphor is formed by coating a metallic oxide having a high polarity to a surface of a green phosphor Zn2SiO4:Mn with a thickness 10 nm to 0.5 ?m. The concentration of a metallic oxide is in a range of 1 to 50 weight % with respect to the green phosphor. According to the green phosphor for the plasma display panel of the present invention, which is made with coating, a metallic oxide having a positive polarity to a surface of a phosphor can be adjusted, thereby enhancing the discharge characteristics when the panel is driven.
