Claims

[Scope of utility model registration request]

A fluorescent display tube in which thermoelectrons emitted from a filament installed in a vacuum-tight container are accelerated and controlled by a grid, and display patterns such as letters, numbers, and figures coated with a fluorescent substance selectively collide with each other to emit light. A fluorescent display tube characterized in that it has one or more voltage application points other than both ends of the filament that emit thermoelectrons.
