Abstract
A field emission display (100) includes a cathode plate (110) having a plurality of electron emitters (114), an anode plate (122) having an anode (124) connected to a potential source (126), and an anode voltage pull-down circuit (127) having an input (106) and an output (104). Output (104) is connected to anode (124), and input (106) is connected to potential source (126). Preferably, anode voltage pull-down circuit (127) causes an anode voltage (120) at anode (124) to drop to about ground potential prior to generation of a discharge current by electron emitters (114) for neutralizing positively electrostatically charged surfaces (137, 138) within field emission display (100).
