Abstract
A device for controlling an electric field at a cathode sub-pixel region of a field emission display comprising a cathode substrate having a plurality of emitter lines formed on the cathode substrate and a gate frame having a plurality of gate wires positioned over respective the plurality of emitter lines. Each of the plurality of gate wires has a cross section shaped to produce an electric field between adjacent ones of the plurality of gate wires that is substantially uniform and substantially flat across the cathode sub-pixel region of respective ones of the plurality of emitter lines. The cathode sub-pixel region is defined as a portion of each of the plurality of emitter lines in between the adjacent ones of the plurality of gate wires.
