る利点を有している。A fluorescent display tube having such a CIG structure has a drive circuit section 5.
Since the output section of the display is connected to the anode electrode 4 and the grid electrode 8 in a vacuum, it has the advantage that the number of external terminals can be greatly reduced compared to a general fluorescent display tube that does not have a CIG structure. have.

来る。However, the CIG fluorescent display tube having such a structure has a major problem in the aging method used to improve the brightness of the phosphor. As is well known, the activation and outgassing of the phosphor is achieved by electronic bombardment stimulation from the filament, but in order to increase the luminous efficiency it is necessary to apply a somewhat high voltage, and usually the rated voltage is 2.
Apply ~5 times the anode voltage, and the grid voltage. By applying this voltage, the temperature of both electrodes is increased, and the released residual gas is absorbed by the getter, increasing the degree of vacuum.
Moreover, the luminous efficiency and stability of the phosphor can be improved.

There are only a few C-chips that have a high withstand voltage that is several times higher than the specified voltage required for aging, and they have had the problem of not being able to undergo sufficient aging. For that reason,
Conventional CIG fluorescent display tubes also have problems, such as requiring a method of increasing brightness by increasing the aging time to compensate for the low voltage, which requires a lot of man-hours.

In the figure, a plurality of wiring films 2, an insulating film 3, segment electrodes 4, and an anode substrate 6 which also serves as a drive circuit section (also referred to as a pad section) 5 are laminated and deposited on a glass substrate 1, and a pad is placed on the anode substrate. An external lead-out lead 7 serves as an input terminal of the section 5, and a so-called frame electrode group arranged on a filament cathode 9 is placed at an appropriate distance from a grid 8 integrated with the external lead-out lead 7. Further, an IC chip 11 is mounted on the pad portion 5 by a bonding method or the like, and the entire board is sealed with a light-transmitting cover glass 1θ with low melting point glass, and the terminals of the external drawer portion 7 are energized. , C via the IC chip 11
It has a structure that drives an IG fluorescent display tube. In the present invention, the external lead 24 serving as the negative electrode of the filament cathode 9 and the external lead 25 connected to the Vas [pole of the IC chip 11 are led out to the outside of the vacuum as separate terminals.

が確認された。In the figure, filament power supply 20 and driver power supply 2
An aging power supply 30 is connected between the terminals 10 and 10. That is, as a new aging method, a rated voltage is applied to the circuit section 5 from the driver power supply 21, totaling 1! The electrode is left in the ON state, and then the aging power supply 30 is applied to apply a negative voltage to the bias of the filament to increase the relative potential between the filament and the anode/grid electrode, thereby aging the phosphor. That's what I'm trying to do. In this method, the rated voltage is applied to the drive circuit 5 (IC chip) itself, and all its outputs are turned on. Therefore, there is no need to consider the withstand voltage of the IC chip at the output end. On the other hand, by moving the potential of the filament in the negative direction using the aging power supply 30 provided separately, the potential of the filament and the potential between the anode and the grid electrode are relatively increased, and the voltage between the normal filament and the anode and the grid electrode is increased. Aging is performed by applying a voltage 2 to 5 times higher. As a result of reliability evaluation tests, the CIG fluorescent display tube of the present invention, in which the phosphor portion was aged (increased brightness and gas discharged) at such a high voltage, exhibited excellent characteristics with a small rate of brightness decline. This was confirmed.

４す、信頼性の高い商品を得る事が可能となった。As described above, in the fluorescent display tube having the CIG structure according to the present invention, the external terminal lead is independently led out from the VSS electrode, which is the power supply terminal of the drive circuit section disposed on the glass substrate, to outside the vacuum. As a result, new aging methods such as those described above have become possible. This aging method is a very effective means for CIG fluorescent display tubes, and has made it possible to obtain highly reliable products.
