Claims

[Scope of utility model registration request]

(1) It has a plurality of display bodies consisting of a plurality of segments,
Each segment is arranged on the same plane of the substrate, and has an anode that is commonly connected within each segment, and control electrodes that are arranged alternately with an insulating space between them and are commonly connected within each display body. a fluorescent display tube having a phosphor layer coated on the surface of the anode opposite to the cathode, which emits light by the impingement of electrons from the cathode; Segment scanning means for supplying a segment scanning signal; and a light emission command for selectively supplying a light emission command signal to a control electrode of each display body to which a segment to be emitted among the segments to which the segment scanning signal is supplied belongs. A fluorescent display device comprising a signal means.

(2) The segment scanning means sends an anode signal to the anode of each segment held at a first blocking voltage that blocks electrons from hitting the control electrode as a segment scanning signal in place of the blocking voltage. The light emission command signal means is maintained at a second blocking voltage that prevents the phosphor layer from emitting light. Utility model registration claim 1: A second light-emitting voltage that enables the phosphor layer to emit light is supplied to the control electrode of each display body as a light-emission command signal in place of the blocking voltage. Fluorescent display tube device as described.
