Abstract

A field emission display (100) includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a bulk-resistive spacer (108) extending between the anode plate (104) and the cathode plate (102). The bulk-resistive spacer (108) is made from an electrically conductive material. The resistivity of the electrically conductive material is selected to remove impinging charges while preventing excessive power loss due to electrical current through the bulk-resistive spacer (108) from the anode plate (104) to the cathode plate (102).
