ABSTRACT:
A RGB phosphor system for a carbon nanotube (CNT)/field emission device (FED) display operated between about 4-10 kV. The RGB phosphor system is formed on an interior surface of a screen of the CNT/FED display. The RGB phosphor system includes ZnS:Cu, Al (green phosphor), ZnS:Ag,Cl (blue phosphor) and Y2O2S:Eu+3(red phosphor). The average particle size for each of the green, blue and red phosphors should be about 3-4 microns.
