Abstract
A spacer (44) for a flat-panel display is formed with a main spacer portion (60), typically shaped like a wall, and a face electrode (66) situated over a face of main spacer portion. The spacer is inserted between two opposing plate structures (40 and 42) of the display. The face electrode causes electrons moving from one of the plate structures to the other to be deflected in such a manner as to compensate for other electron deflection caused by the presence of the spacer. The face electrode is divided into multiple laterally separated segments (661-66N) to improve the accuracy of the compensation along the length of the spacer. A masking step is typically utilized in defining the widths of the segments of the face electrode.
