Abstract
A field emission display (FED) consists of a cathode plate including a plurality of emitter lines formed on a cathode substrate, a gate frame positioned over the cathode plate, the gate frame including a plurality of gate wires, and an anode plate including a plurality of phosphor lines positioned over the gate frame. The plurality of phosphor lines are aligned with the plurality of emitter lines. In some variations, the FED includes a plurality of linear isolation barriers separating one or more of the plurality of emitter lines. In some variations, the linear isolation barriers are in the form of ribs or trenches.
