Paper Abstract

This paper reports for the first time the electrical conduction and breakdown characteristics of thin-wall ceramic spacers bridging two thin-film electrodes, which represent the FEA cathode and the phosphor anode in a field emission display (FED). Techniques to set up a high aspect- ratio thin-wall spacer were specially developed, without use of glue. An extra-low light detection 3D-imaging system using an intensified CCD camera was developed, without use of glue. An extra-low light detection 3D-imaging system using an intensified CCD camera was developed which was able to identify the location of any light activity in the stressed vacuum-gap, indicative of imminent device failure. The result of this work are highly encouraging in that an approximately 1000 micrometers tall spacer can support approximately 18 kV, at least 80 percent above the expected operational voltage of high voltage FEDs. However, it is likely that the breakdown strength can degrade in the presence of electronic bombardment from the field emitted array in an FED - a subject for future investigations in our laboratory.
