  • Patent number: 5312279
    Abstract: A vacuum fluorescent display and a manufacturing method thereof are disclosed. The vacuum fluorescent display has a faceplate and a substrate forming a vacuum-space, segments, filaments, grids, pin leads, stands for fixing filaments and a stationary base for fixing the stands. The stationary base is a hollowed-out rectangle which includes a pair of parallel setters for welding the stands on opposing sides of the substrate and a pair of spacing strips for maintaining the interval between the setters. The base is fixed to the substrate, and then setters are separated from each other by removing the spacing strips. The ends of setters extend outwardly from the vacuum-space to serve as a conductor to the filament.
