  • Method of driving field emission device (FED) and method of aging FED using the same
    Publication number: 20070257865
    Abstract: A method for driving a field emission device (FED) applies an alternating (AC) voltage as a driving voltage for emitting electrons in a field emission device comprising cathode electrode including an emitter and an anode electrode facing the cathode electrode. A method for aging an FED uses a constant voltage so that electrons cannot be emitted from the electron emission source, and an AC voltage so that electrons can be periodically emitted from the emitter when the FED is aged.
