Claims (1)
陽極基板と対向した位置に張られたフイラメント
より放出される熱電子により、前記陽極基板上に
塗布した蛍光体を発光させ、表示を行う蛍光表示
管において、前記フイラメントが、電気的に独立
した複数のブロツクに分かれて張られていること
を特徴とする蛍光表示管。 A fluorescent display tube that is housed in a vacuum-tight container and that displays by causing a phosphor coated on the anode substrate to emit light using thermionic electrons emitted from a filament that is placed opposite the anode substrate via a grid. A fluorescent display tube, characterized in that the filament is divided into a plurality of electrically independent blocks.
