Patent ID: 6958739

Claim:
An aging apparatus of a field emission device provided with a scan driving unit and a panel, the apparatus comprising: an aging operation controlling unit for performing an aging operation by controlling a high voltage of a pulse form applied to an anode electrode of the panel and a voltage applied to the scan driving unit, wherein the aging operation controlling unit comprises: a power controlling unit for applying a power to the scan driving unit by an external power control signal; a pulse generating unit for receiving an external pulse control signal and thereby outputting a pulse signal having a corresponding frequency and a duty cycle; a high voltage applying unit for receiving a pulse signal from the pulse generating unit, converting a direct current high voltage into an alternating current high voltage of a pulse form, and thereby applying to the anode electrode; and a program controlling unit for detecting a voltage and a current applied to the anode electrode of the panel from the high voltage applying unit, comparing the detected current value with a preset limitation current value, and outputting a pulse control signal and a power control signal to the pulse generating unit and the power controlling unit, respectively.
