Characterization of an advanced HEED (High Efficiency Electron-emission Device)

We recently developed a new-type cold cathode termed HEED (High-Efficiency Electron-emission Device) based on the Metal-Insulator-Semiconductor (MIS) diode. It has been shown that by arranging the device and surface structures the emission characteristics can be significantly improved. Using the advanced HEED as an excitation source, a 4-inch prototype flat panel display has been fabricated on a glass substrate. The panel operates well with a practical brightness at a relatively low driving voltage. The occasional reactivation technique is very effective to prolong the operation life of this device.
