Anodically bonded elements for flat-panel displays
Abstract:
A flat-panel display and process for forming the flat-panel display having an array of spacer columns anodically bonded to one of the inner major faces on one of the generally planar plates of the evacuated, flat-panel video display. The process includes providing 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.
