Abstract: The apparatus of the invention is adapted for operating multiple position display devices having a plurality of groups of display cathode segments or elements, with corresponding elements electrically interconnected, an anode electrode associated with each group of display segments, and an auxiliary electrode common to all of the groups of electrodes for preventing spurious glow between them. The simplified circuit biases the OFF cathodes from a voltage divider common to them and the auxiliary electrode, thus eliminating separate biasing for the OFF cathodes. The signals applied to the display tube or panel are also blanked during an interval in advance of signal transitions in the device, for inhibiting spurious glow under varying conditions of operation. Voltage divider apparatus also is provided for biasing the OFF anodes in a nonconductive state at a potential proportional to the tube bias potentials.
