PRINTABLE NANO-SIZED COLD CATHODE SLURRY AND ITS USE

WIPO Patent Application WO/2006/081715

A1

The present invention disclose a printable nano-sized cold cathode slurry, and a method of producing a field emission type cold cathode using the same. The slurry use electroconductive nano-sized materials, inorganic binders, organic solvents and adjuvants as its main components. The weight ratio of the electroconductive nano­sized materials and the inorganic binders is 0.1:110:1. The organic solvents and the adjuvants in the slurry are removed by heat treatment. In the cold cathode produced with the slurry, the electroconductive nano-sized materials and the inorganic binders form a compactly cumulated composite emission structure with a thickness of several microns to hundreds microns. In order to further increase the emission characteristics, using a selective etching technology aim at the inorganic binders to remove the solidified binders on the surface, and exposure the electroconductive nano-sized materials beneath them. So, the field emission characteristics of the cold cathode are increased. The cold cathode slurry can be used to produce film-type or array-type cold cathode, be used as a electric source in field emission type display device, cold cathode light source and other places need cold cathode.
