| Abstract: | Abstract— 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 to assure a good color gamut and high anode efficiency without requiring specific focusing electrodes or structure. A computer simulation, written to analyze and improve the device design, shows good correlation with the experimental data and helps predict design margins. A full‐color frit‐sealed display built with this approach demonstrates an excellent color gamut of the phosphor, and the model predicts avenues for further color‐gamut improvements. |
