Abstract
PURPOSE: To eliminate the depth effect of the distance between a face plate and a fluorescent screen by providing a fluorescent layer on the face plate.
CONSTITUTION: A positive potential is applied to a grid 7 and an anode by making a filament 8 discharge thermions by supplying electric current and heating the filament 8 after activating the same. The current flowing from the filament 8 to the anode excites a fluorescent substance 6. The fluorescence projects outside throuth a transparent electrode 5, a translucent electrode 3 and a face plate 2. The brightness is adjusted according to the purposes by controlling the anode current density.
