御する構成になる螢光表示装置。 A large number of control electrodes are arranged in parallel at predetermined intervals on the anode on which the phosphor layer is adhered, and the control electrodes are scanned at a predetermined period to select pixels, and synchronized with this scanning. A fluorescent display device in which a display signal is applied to an anode to form a display, comprising: a scanning unit that generates a scanning signal for the control electrode; a driver unit that generates a drive signal for the control electrode based on the scanning signal of the scanning unit; A gate circuit section interposed between this driver section and the scanning section accepts a pulse generated in synchronization with the scanning signal as a trigger pulse, and the next trigger pulse is input within the time of its own output pulse width. and a retriggerable mono-multivibrator that retrigger and maintain the output state at a constant value when the retriggerable mono-multivibrator is activated, and the fluorescent display device is configured to control opening/closing of the gate circuit section by the output of the retriggerable mono-multivibrator. .
