Abstract
We have developed a surface conduction electron emitter (SCE) for next-generation flat displays. PdO thin films (approximately 10 nm) produced by the ink-jet process were used for forming the surface conduction electron emitter. The films were electroformed and activated while a certain voltage was applied, and an electron emitter with good characteristics was obtained. A current density of approximately 30 mA/cm2 was attained when an anode voltage of 10 kV was applied. We confirmed operation for 60,000 hours by an acceleration test at a current density of 3 mA/cm2. This current density is required for “good brightness” on the surface conduction electron emitter display (SED).
