Patent ID: 6943487

Claim:
A vacuum fluorescent display, comprising: first and second substrates provided opposing one another, and a side glass provided between the first and second substrates to seal a space therebetween; filaments for emitting electrons when a voltage is applied thereto; first and second filament supports mounted to one of the substrates and supporting opposite sides of each of the filaments; and an anode provided on at least one of the substrates, the anode being illuminated by electrons to realize images; with at least one of the filament supports are formed of complex-type, the complex type filament supports include a fixed plate which is fixed to the one of the substrates, at least one tension arm mounted to the fixed plate, at least one tension head provided on a distal end of each of the tension arms, and at least one tensionless head to which one of the filaments is attached, the tensionless head being mounted to one of the tension arms.
