Patent ID: 7710362

Claim:
An electron emission display (EED), comprising: an anode; a panel electrode unit including a scan electrode that extends in one direction of a lattice type panel and a data electrode that extends across the scan electrode; a power supplier for outputting an anode voltage for driving the anode and a panel driving voltage for driving at least one electrode of the panel electrode unit; a driving unit for receiving the panel driving voltage, and for driving said at least one electrode of the panel electrode unit in response to a first control signal; a timing controller for outputting the first control signal for controlling the driving unit; an anode voltage supplier for applying the anode voltage to the anode; an anode voltage detector for detecting the anode voltage, for dividing the detected anode voltage by a predetermined division ratio, and for outputting a result; a comparator for comparing the detected and divided anode voltage with a reference voltage, and for outputting a comparison result as a second control signal; and a first switch for switching the panel driving voltage to said at least one electrode of the panel electrode unit in response to the second control signal.
