Field Emission Property Studies and Fabrication of Diode FED with Improved Cold-Cathode Emitter

Abstract

Using the soda-lime glass as substrate, the improved printed cold-cathode emitters were prepared for the field emission display device. The indium-tin-oxide film over the substrate surface was divided into discrete indium-tin-oxide stripes. With the screen-printing process, the two parallel silver electrodes were fabricated on one indium-tin-oxide stripes and the carbon nanotube was prepared over the silver electrode surface. It was found that the carbon nanotube on the edge of cathode electrode would emit more electrons. For preventing the damage of carbon nanotube cathode, the previous silver slurry baking process was adopted. Then, the baked silver slurry layer and the printed carbon nanotube pastes would be simultaneous sintered. The detailed fabrication and vacuum-packaging process for the whole display device were also given. The fully-sealed display device possessed better field emission property and high display brightness for the green phosphor, whose fabrication process was simple and low-cost.
