Abstract
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.
Claims6
A fluorescent luminous device comprising:
- an anode substrate;
- an anode including a plurality of anode chains, wherein each of said anode chains includes a plurality of anode dots spaced at predetermined intervals on said anode substrate, and wherein said anode dots of said anode chains are connected to corresponding anode dots of other anode chains of said plurality of anode chains;
- an anode drive means for driving said anode dots;
- a plurality of cathodes arranged above respective anode chains of said plurality of anode chains;
- and
- cathode selection means for applying voltages to respective cathodes of said plurality of cathodes independently from other cathodes of said plurality of cathodes, so as to select said anode chains.
