Abstract
The present invention provides a spacer assembly which is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly when the spacer assembly is subjected to flat panel display operating voltages. The present invention further provides a spacer assembly which accomplishes the above achievement and which does not degrade severely when subjected to electron bombardment. The present invention further provides a spacer assembly which accomplishes both of the above-listed achievements and which does not significantly contribute to contamination of the vacuum environment of the flat panel display or be susceptible to contamination that may evolve within the tube. Specifically, in one embodiment, the present invention is comprised of a spacer structure which has a specific secondary electron emission coefficient function associated therewith. The material comprising the spacer structure is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly when the spacer assembly is subjected to flat panel display operating voltages.
