Abstract
A fluorescent display tube, which has short-length filaments, can be driven by applied voltage of 3-8V to be used for a general fluorescent display tube. The fluorescent display tube can emit sufficient thermal electrons even if the number of filament cathodes is decreased to reduce power consumption of the filaments. The filament cathode is arranged between a first and third supporting plates by one end thereof fixed to the first supporting plate and the other end thereof fixed to the third supporting plate, and the filament cathode having an equal length with the filament cathode extended between the first and third supporting plates is arranged between the second and third supporting plates.
