Abstract
A field emission display apparatus including a field emission display panel and a driving device for the field emission display panel. The driving device includes a power supply unit, the power supply unit including an abnormal current detection unit and a discharge circuit. The abnormal current detection unit generates an arc-current detection signal when the value of a current flowing between a negative anode voltage terminal of the field emission display panel and a common ground line is larger than an upper limit. The discharge circuit generates a short circuit between an anode plate of the field emission display panel and the negative anode voltage terminal when the arc-current detection signal is generated from the abnormal current detection unit.
