<p>A drive circuit for a fluorescent display tube used for displaying numerals, characters, and so on, which circuit includes a plurality of drivers for switching the potential of segments and/or grids of the fluorescent display tube. Part or all of the drivers each has a plurality of transistor elements whose drive timings differ from each other, thereby decreasing the transition speed of the output signals of the drivers and preventing the drivers from being destroyed by excessive voltage caused by the switching operation thereof.</p> |
