碩士 === 國立中正大學 === 化學工程研究所 === 105 === The field emission planar lighting device and seven-segment field emission display were studied. The lighting devices were with a interdigitated cathode and anode structure which allowed lateral electron bombardment to the phosphors. The experiment parameters in the study of lighting device included the voltages, height of spacers, DC/AC operation and the voltages of electric field control electrode, which is a parallel plate to the planar cathode-anode structure. The result shows a maximum luminance of 19210 nits with the uniformity of 93.7 % can be achieved with the anique structure and an optimal operational condition. Seven-segment display with a designed planar structure was studied. The luminance of the seven-segment display is in the range of 5000-9000 nits. Key word: Carbon nanotube、Field emission、Phosphor
