Abstract: With carbon nanotube as cold cathode, the field emission display based on the improved film-electrode was fabricated. The indium tin oxide film covered on the glass surface was etched to form the film-electrode. For one film-electrode stripe, the left bar electrode and the right bar electrode were formed on the both side of the bottom electrode. The carbon nanotube would be prepared on the bottom electrode surface. The cathode covering layer fabricated with the sintered insulation slurry would cover the left and right bar electrodes. It was confirmed that the emission current could be controlled by the formed electric-field with the improved film-electrode.

Abstract: With photolithography process and screen printing technique, the compound cold cathode electrode was developed on the cathode glass plate for improving the field emission ability and emission uniformity of CNT cathode. The compound cold cathode electrode mainly consisted of the indium tin oxide (ITO) blocks which was the divided ITO thin film, the bar silver stripes fabricated by the solidified silver slurry and the cathode insulation layer with good insulation performance. Carbon nanotubes were prepared to form the field emitters, and the diode type field emission display (FED) was fabricated. The manufacture process was also presented in detail. The vacuum sealed FED exhibited better field emission characteristic, low operating voltage and high display brightness.

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.

Abstract: Silver slurry was used as conducting material, and the improved silver cathode electrode was fabricated. The CNT paste formed as field emitters was screen-printed on the surface of silver cathode electrode. The diode FED panel with CNT field emitters was sealed, and the fabrication of cathode substrate and anode substrate was described. The screen-printing technology and the sintering process were employed in the course of device fabrication for the silver cathode electrode. The field emission current was measured and the emission image was presented. The packaged FED showed good field emission characteristics and better field emission uniformity, which the manufacture process was also low-cost, feasible and simple.
