37.3: A Carbon Nanotube Field Emission Display with Simple Electron Beam Trajectory Control

A unique gated cathode structure for a Carbon Nanotube-based field emission display has been designed and built. This structure optimizes the electron beam profiles so as to assure high anode electron efficiency and a good color gamut without requiring specific focusing electrodes or structure. A computer simulation written to analyze and aid with the design shows good correlation with the experimental data and also helps to predict design margins. A full color frit-sealed display built with the approach demonstrates an excellent color gamut of the phosphor, and the model predicts avenues for increasing the color gamut further.
