| 摘要 |
The circuit of the invention is adapted for operation with a display device which includes a plurality of side-by-side groups of display cathode segments, each group having an anode electrode, and there being an auxiliary electrode common to all of the groups of electrodes for electrically isolating each group of display segments and preventing spurious glow between groups. In the circuit, means are provided for providing current flow to the auxiliary electrode in proportion to the total number of display cathode segments glowing at any instant.
