Abstract
PURPOSE: To make uniform the illuminating luminance of the fluorescent display electrode, by adjusting the distance between the filament and fluorescent display electrode to between the filament and control electrode every electrode.
CONSTITUTION: A number of fluorescent display electrode 3 is placed in a row in front 2 of the rectangular shape base 1, and the filament 4 is extended before it, and the control electrode 6 of lattice shape is placed between the filament 4 and the fluorescent display electrode 3. Further, the electrodes 3 and 6 are of the same potential. In the display unit of thus constitution, the intermediate anchor 11 makes smaller the distance between the intermediate part 4a and the fluorescent display electrode 3 than that at the both ends 4b. Thus, the uniform illuminating luminance is made by correcting the darker luminance of the display electrode 3 at the middle due to the effect of the filament AC drive than the display electrode 3 at the both ends. Or, the similar effect can be obtained by locating the arrangement of the control electrodes 6a,6b... closer to the filament 4 according to the closer distance for the intermediate section.
