A Study for the Fabrication of Wall-Shaped Support Spacer in a Field Emission Display Panel

Abstract

Using insulation slurry as composite material, the wall-shaped support spacer was designed and fabricated on the cathode back-plane. In the fabrication course of support spacer, the high effective screen-printing technique was employed to prepare the insulation slurry layer on the separation layer surface of cathode back-plane. And the conventional sintering process was utilized to solidify the printed insulation slurry layer subsequently. Many insulation slurry layers were sintered and stacked to form the support spacer arranged in equilateral triangle form. The carbon nanotube was used as field emitter, and the field emission display panel was fabricated and sealed with glass frit, which possessed good field emission characteristics and better image uniformity.
