ABSTRACT:
The present invention provides a method for aging a field emission cold cathode, wherein a gate electrode of the field emission cold cathode is not applied directly with the voltage. The gate electrode remains floated electrically. A high voltage is applied to either an anode electrode or a convergence electrode so as to generate a field with a sufficiently large intensity for causing electron emission from a pointed top of a cone-shaped cathode toward the anode electrode or the convergence electrode.
