英文摘要：

On cathode glass faceplate the new integral type cold cathode was developed. The printed silver slurry was sintered to form the silver bottom electrode. The thin-layer bottom electrode paste including a great deal of carbon nanotube was prepared, and was screen-printed on the silver bottom electrode surface. The ordinary carbon nanotube paste was fabricated on thebaked thin-layer bottom electrode paste. The two types of pastes were simultaneous sintered in the sintering furnace with the protection of high purity argon atmosphere. The sintered thin-layer bottom electrode would combine with the silver bottom electrode, which the carbon nanotube layer was covered on its surface. In one cathode pixel there were two carbon nanotube field emitters. Due to the spare carbon nanotube field emitter, the service life of field emission display could be prolonged greatly. Using thin-layer bottom electrode as interface layer between the silver bottom electrode and the carbon nanotube layer, the adhesion property of carbon nanotube was improved and the reliable ohmic contact had also been confirmed. With carbon nanotube as cathode material, the integral type cold cathode field emission displaY was fabricated, which exhibited good luminescence image quality and better field emission characteristics. Comparing with the ordinary carbon nanotube cathode field emission display, the turn-on electric-field could be reduced from 2. 11 V//am to 1. 68 V/μm, the maximum field emission current could be enhanced from 905. 7 μA to 1 866.2 μA, and the field emission current fluctuation at 367 μA would not exceed 4.5%. The integral type cold cathode field emission display has subsequently been operated for more than 10 days with stable luminance brightness.
