Fabrication of Small Triode-Type Cold-Cathode Field Emission Display with Staggered Gate-Electrode Layer

Abstract

Carbon nanotube used as cold cathode, the triode FED with staggered gate-electrode layer structure was fabricated with the screen-printing technique and conventional sintering process. Using superior mica plate as gate substrate material, the silver slurry was prepared to form the staggered gate electrode. The insulation layer was also manufactured over the gate substrate surface. The design and fabrication of the staggered gate-electrode layer was described in detail. By means of glass frit, the whole panel structure was vacuum-sealed. With the fabricated staggered gate-electrode layer, the modulation of electron emission from CNT field emitter by the gate voltage was confirmed. The packaged tridoe FED possessed better field emission uniformity, good image display performance and high display image brightness.
