[15p-F203-14] Low-power-consumption flat-panel light-emitting device driven by field-emission electron source using high-crystalline carbon nanotube
Keywords:carbon nanotube, field emission, cathode luminescence device
The flat-panel light-emitting device constructed to play a role in reducing power consumption and saving energy in field-emission electron sources featured a line-sequential-scanning-type electrode structure equipped with electrodes for on-and-off controls of electron emissions on a thin electrode film, on which a high-crystalline single-walled carbon nanotube (SWCNT) was uniformly distributed. The device successfully emitted electrons on the flat panel in a stable manner. A technology for amplifying the luminance output by controlling the persistence characteristics of a fluorescent screen was also successfully developed. By combining such elemental technologies, a flat-panel light-emission device, as a stand-alone plannar lighting, that achieves high-luminance efficiency of over 60 lm/W and energy-conserved driving was assembled.
We formulated a fundamental design technology for a flat-panel light-emission device that can control electron-emission switching in an arbitrary manner. In our attempt to assemble a field-emission (FE)-type electronic device through a wet process, we achieved low power consumption and high-luminance efficiency. Based on the results, the application of a high-crystalline SWCNT was determined to be effective in conserving energy in FE electron sources. The creation of field-emission electron sources that are driven with ultra-low power consumption, along with applications that utilize such devices, are expected in the future.
