Abstract:
1. A field emission system, comprising: an upper substrate; a lower substrate disposed under said upper substrate and a field emission area and a getter area defined therebetween; an anode array formed on an inner surface of said upper substrate corresponding to said field emission area and including at least one first anode wire; a phosphor layer formed under said anode array; a cathode array formed on an inner surface of said lower substrate corresponding to said anode array and including at least one first cathode wire; a carbon nanotube (CNT) field emission array including a plurality of CNT units formed on said at least one first cathode wire and each of said CNT units including a plurality of carbon nanotubes; at least one second anode wire formed on said inner surface of said upper substrate corresponding to said getter area; at least one second cathode wire formed on said inner surface of said lower substrate corresponding to said second anode wire; and a plurality of surface-unsaturated carbon nanotubes formed on said second cathode wire.
