Fabrication of Combined Type Insulation Wall in a Field Emission Display with Carbon Nanotube Emitters

Abstract

Using insulation slurry as material, the combined type insulation wall was developed with the high-effective screen-printing process. Two parts were mainly included for the combined type insulation wall, which was the lower insulation wall prepared on the cathode panel and the upper insulation wall fabricated on the anode panel, respectively. The fabricated combined type insulation wall possessed better insulation performance, and was used to separate the cathode and anode panel. Using carbon nanotube as cathode material, the field emission display with the combined type insulation wall was fabricated, and the detailed manufacture process was also presented. The sealed field emission display showed high luminance brightness, stable emission current and good field emission properties.
