Abstract
A multi-digit luminescent display tube comprises a plurality of luminescent anode segment groups. All anode segment groups may be regularly spaced. Alternatively, at least one single anode segment group may be spaced wider from the remaining regularly spaced ones. A grid is interposed between a cathode and each anode segment group and comprises a pair of grid frame members, or rectangular metal rods, transversely of the cathode. Two of the frame members are made wider on both ends of a series of regularly spaced grids than other frame members of the grid series. Both frame members are also made wider for the single anode segment group than the above-mentioned other frame members.
