Abstract

The invention belongs to luminescent material applied technique field. And it relates to plasma phosphor paste and its synthetic method. The paste is made up of high volatilization point solvent, plasma phosphor, more than two medium materials, and polysiloxanes. The synthetic method includes the following steps: adding the medium material into the high volatilization point solvent; then adding into polysiloxanes to form medium glue liquor; mixing PDP phosphor with the medium glue liquor; and grinding. The formed material has the advantages of simple technological process, and easy operation. And it is adapted for mass production.

Description

technical field [0001] The invention belongs to the technical field of luminescent material application, and relates to a plasma phosphor slurry and its synthesis. Background technique [0002] Currently, in the global flat panel display market, the color plasma flat panel display device has become one of the important development directions in the field of information display because of its unique advantages. In recent years, the market of color plasma flat-panel displays has expanded rapidly, and color plasma TVs have begun to enter families in our country. The color plasma phosphor paste is one of the key materials for the manufacture of plasma displays, which cannot be produced in my country now. Several domestic production and development units of color plasma flat panel display devices use high-priced imported paste, which seriously affects the development of my country's PDP display technology. [0003] At present, domestic phosphor paste is made by uniformly disper...
