The invention is to reduce electricity consumption and increase display quality. An fluorescent indicator tube includes a lamp filament for emitting electrons, a positive pole which forms a fluorescent body on a positive electrode which controls movement of electrons, and a positive driving circuit which drives the positive pole on the basis of output voltage of a charge pump voltage increase circuit on the basis of increased input voltage; the fluorescent indicator tube controls the voltage increase action of the to stop or restart the charge pump voltage increase circuit. For changing of theload, the output voltage is approximately constant, thus improving display quality. In the invention, reduction of the output voltage is achieved by stopping the voltage increase motion, so that electricity consumption is reduced than a situation of reducing voltage by consumping electricity due to heating. 本发明旨在降低电力损耗且提升显示品质。荧光显示管包括发射电子的灯丝、在控制电子的移动的阳极电极上形成荧光体而成的阳极及基于升压输入电压的电荷泵型升压电路的输出电压驱动阳极的阳极驱动电路，所述荧光显示管根据电荷泵型升压电路的输出电压
