Abstract
A high-resolution carbon nanotube (CNT) -field emission display (FED) was investigated for graphic-displays. The sub-pixel size was 0.2mm × 0.6mm. The panel structure was developed based on the unique stack-structure for character-display of 1.0mm-dot-pitch [1]. The configuration of the display was a metal-backed color-phosphor screen, tall-spacer of 0.5–1.0mm height for individual phosphor line, a metal gate-substrate and CVD-grown-CNT on a metal-electrode. In order to realize 2.0–3.0mm tall spacer, we introduced the new rib structure using a metal sheet. And the CNT emitter was grown on a metal electrode by newly developed technology. The diameter of deposited CNT was reduced down to 6–10nm. And also, a laser irradiation was effective to improve emission characteristics. The experimental panel was performed high luminance and high resolution display. The screen size was 36mm × 36mm.
