これを改良し、ドライバーＩＣやマイクロコンピュータ
などのＩＣ素子チップを蛍光表示管の真空外囲器内に保
持し、システムトータルとしてのスペース効率をあげる
と共に、プリント基板を有効に活用して、コスト低減を
狙ったＣＩＧ （チップイングラス）タイプ蛍光表示管
がある。By improving this, IC element chips such as driver ICs and microcomputers are held within the vacuum envelope of the fluorescent display tube, increasing space efficiency as a whole system, and making effective use of printed circuit boards to reduce costs. There is a CIG (chip-in-glass) type fluorescent display tube aimed at this purpose.
上述した従来のＣＩＧタイプ蛍光表示管は、真空外囲器
の大きさに制限があり、電気的に駆動するのに必要なド
ライバーＩＣチップを全て真空外囲器内に入れることは
極めて難しく、コスト低域にも限度があった。The conventional CIG type fluorescent display tube mentioned above has a limited vacuum envelope size, and it is extremely difficult to fit all the driver IC chips required for electrical drive into the vacuum envelope, resulting in high cost. There were also limits to the low range.
ここで、真空外囲器の外面を利用してドライバーＩＣチ
ップ等を搭載する方法が考えられた。Here, a method of mounting a driver IC chip and the like using the outer surface of the vacuum envelope has been considered.
すなわち、真空外囲器の一部を突出させて、この部分に
コの字状の金具を嵌合し、真空外囲器内と外面との電気
的接続をなすタイプがある。That is, there is a type in which a part of the vacuum envelope protrudes and a U-shaped metal fitting is fitted into this part to establish an electrical connection between the inside of the vacuum envelope and the outer surface.
しかし、この構造においては、コの字状の金具を保持す
るためエポキシ樹脂を被せたり、又、シリコン系の樹脂
をかぶせたりしなければならず、高温と低温時の熱膨張
率の違いにより、真空外囲器の一部にクラックを生じて
、表示器としての機能を失うなどの欠点があった。However, in this structure, it is necessary to cover the U-shaped metal fitting with epoxy resin or silicone resin to hold it, and due to the difference in thermal expansion coefficient at high and low temperatures, There were drawbacks such as cracks appearing in a part of the vacuum envelope and loss of function as an indicator.
本発明の目的は、容易にドライバーＩＣチップを搭載で
き、コスト低域が可能で表示器としての機能を失うこと
のない蛍光表示管を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a fluorescent display tube that can be easily equipped with a driver IC chip, can be manufactured at low cost, and does not lose its function as a display device.

チップに電気的に接続されたリードを有している。The present invention has an anode coated with a phosphor, a grid for controlling light emission, and a filament serving as an electron supply source in a vacuum envelope, and the anode is provided on a part of the outer surface of the vacuum envelope. In a fluorescent display tube including a driver IC chip that drives at least one electrode of the grid and the filament, one end is connected to the anode, the grid, and at least one electrode of the filament. the driver IC, the other end of which passes through the vacuum envelope, and is provided on the outer surface of the vacuum envelope;
It has leads electrically connected to the chip.
次に、本発明の実施例について図面を参照して説明する

第２の実施例は、第２図に示すように、視認方向が第１
図の第１の実施例と逆の場合で、平面発光形とよばれる
蛍光表示管に適用した例である。In the first embodiment, as shown in FIG. 1, the lead 2 passes through the vacuum envelope and is pulled out to the outside, and is bent to form an Ag pad on the surface of the vacuum envelope 2 in advance. The lead connection portion 4 is soldered to the lead connection portion 4. In the second embodiment, the circuit connecting the lead connection portion 4 and the driver IC chip 3 may both be formed of a thin film such as A2 or ^ff+Ni, as shown in FIG. 1st
This is an example in which the present invention is applied to a fluorescent display tube called a flat emission type, which is the opposite case to the first embodiment shown in the figure.
