Abstract
A partial discharge method for operating a field emission display (,) having an anode (,), a spacer (,), and a plurality of electron emitters (,) includes the steps of causing electron emitters (,) to emit electrons (,), applying a scanning mode anode voltage to the anode (,), where the scanning mode anode voltage is selected to cause electrons (,) to be attracted toward anode (,), and, thereafter, applying a partial discharge voltage to anode (,). The partial discharge voltage is equal to about a maximum discharge voltage, where the maximum discharge voltage is defined as the maximum voltage that can be applied to anode (,) during the discharge mode of operation while maintaining invisibility of spacer (,).
