Development of an advanced Heed (High Efficiency Electro-Emission Device)

It is shown that the emission characteristics of a previously reported MIS-type electron emission device termed HEED (High Efficiency Electro-Emission Device) can be significantly improved by appropriate arrangements of the emission site structures. Using this emitter as an excitation source, a 4-inch prototype flat panel display has been fabricated on a glass substrate. The panel operates well at a practical brightness of 2000 cd/m/sup 2/.
