【発明の詳細な説明】 本発明は螢光表示管の駆動方法に関する。[Detailed description of the invention] The present invention relates to a method for driving a fluorescent display tube.

とするためには。Now, FIG. 3 shows a conventional method for driving a multi-digit fluorescent display tube. Direct current or alternating current is applied to the filament, and a pulse with a voltage of eD=eo in Fig. 3 is applied to the anode segment and the grid, and by selecting the anode segment, an arbitrary character is displayed. . Turn off the opposite digit
In order to do that.
フィラメントに連続的に電圧を印加しているため。Because voltage is continuously applied to the filament.

、カプトオフ電圧ｌｘを必要とする。Even if the grid is set to O(V), the electron current flows in avoiding the vicinity of the grid lines, so it is not possible to completely extinguish the light emission, so a cap-off voltage lx is required.
本発明の目的けこの欠点を除去する駆動方法を提供する

Turns ON during planking/grid signal time. At this time, the grid and the anode segment are in the OFF state, and there is no electron flow from the filament to the anode, and the anode segment does not emit light. Therefore, if the front drive method shown in FIG. 6 is adopted, it is sufficient to satisfy the potential relationship shown in FIG. 4, and the conventional cutoff voltage BK becomes unnecessary.
