Abstract
A spacer ( ) for a flat-panel display is formed with a main spacer portion ( ), typically shaped like a wall, and a face electrode ( ) situated over a face of main spacer portion. The spacer is inserted between two opposing plate structures ( and ) 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 ( ) 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.
