The prototype of the field emission display with carbon nanotube emitter is developed in this study. The cathode structure is based on the typical top‐gate structure, and electron focusing gate and resistive layer are applied. To improve the brightness and color gamut of the prototype, new phosphor material, SrGa 2 S 4 : Eu, is adopted instead of conventional CRT‐green phosphor. By replacing the green phosphor, the prototype shows significant improvements in the brightness and color gamut. At the anode voltage of 7 kV and the anode current of 2∼3 μA/cm 2 , the brightness is higher than 600 cm/m 2 . The luminous efficiency of the prototype is about 7.7 lm/Watt. The images from color video operation of the prototype are shown.
