Fluorescent luminous device including cathodes that receive independently controlled voltages
A fluorescent luminous device which is capable of eliminating arrangement of independently controllable control electrodes and a power supply for applying a negative potential to the control electrodes. A plurality of anode chains and a plurality of filamentary cathodes are arranged in a manner to correspond to each other. A potential across the cathodes is changed over between a zero or negative potential and a positive potential to control the anode dots.
