Abstract

A process for anodically bonding an array of spacer columns to one of the inner major faces on one of the generally planar plates of an evacuated, flat panel video display. The process includes using a generally planar plate having a plurality of spacer column attachment sites; providing electrical interconnection between all attachment sites; coating each attachment site with a patch of oxidizable material; providing an array of unattached permanent glass spacer columns, each unattached permanent spacer column being of uniform length and being positioned longitudinally perpendicular to a single plane, with the plane intersecting the midpoint of each unattached spacer column; positioning the array such that an end of one permanent spacer column is in contact with the oxidizable material patch at each attachment site; and anodically bonding the contacting end of each permanent spacer column to the oxidizable material layer.
