ABSTRACT:
A fluorescent display tube includes in the casing a plurality of anode display portions formed of segment electrodes each having a fluorescent material layer thereon, cathodes and control electrodes disposed opposite to the anode display portions, lead-in wires led out in an air-tight manner from the casing and electrically connected to the segment electrodes, the control electrodes and the cathodes, a plurality of conductive section each connected to the adjacent common segment electrodes through a corresponding conductive wiring film, the lead-in wires for the segment electrode terminal each having at the end thereof in the casing a contact with a spring portion, the contact coming in contact with the corresponding conductive section by the action of the spring portion as well as a conductive adhesive applied thereto thereby establishing an electrical connection.
A method of producing a fluorescent display tube includes forming an anode plate, forming electrode assembly framework, forming a casing using the anode plate, upper cover and the electrode assembly framework by sealing and removing unnecessary parts after sealing.
