Field emission system and method for improving its vacuum

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 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 anode wire.
