At the same time, the segments are connected in series through voltage drop means, and by applying a voltage to one of the segments, a voltage different from the voltage is applied to the other segments due to the voltage drop of the voltage drop means. ,
A fluorescent display tube characterized in that the brightness of each segment is different from each other. (2) The fluorescent display tube according to claim 1, wherein the voltage drop means is a resistive element. (3) The fluorescent display tube according to claim 1, wherein the voltage drop means is a diode.
