[Industrial applications]

The present invention relates to an aging method for a gas discharge display panel in which the aging is facilitated by improving the electrode terminal structure so that the discharge in the entire discharge display area can be secured and the disconnection of the electrode can be complemented.

In recent years, with respect to the display shape of the dot matrix type gas discharge display panel, display panels of various sizes have been used in accordance with the diversification of display devices to which these are applied, and it is demanded that a large variety of products be produced in small quantities. There is.

Therefore, in the aging process in the production of the gas discharge display panel, the versatility of jigs such as an aging short bar for commonly connecting a plurality of electrode terminals of the display panel is improved and the number of bar jigs is increased. There is a need for an aging method for a gas discharge display panel in which the process efficiency is improved, the discharge is secured in the entire discharge display area, and the electrode disconnection can be complemented to improve the electrode terminal structure to facilitate aging.

[Conventional technology]

Conventionally, in a dot matrix type gas discharge display panel (hereinafter abbreviated as PDP), the number of display electrodes is increased and the arrangement pitch of the electrodes is narrowed due to the demand for higher resolution. Since the space between the connection terminals provided at one end of the electrode is inevitably narrowed and solder connection with the drive circuit becomes difficult, the connection terminals 3 are alternately arranged on both ends of the glass substrate 1 as shown in FIG. The width of each terminal is expanded while the distance between the adjacent terminals is widened.

It should be noted that the terminal group of the electrodes 12 on the other glass substrate 11 facing the glass substrate 1 via the gas discharge space has the above-described arrangement according to the size of the display screen, or the third group.
It is led out only to one side of the substrate 11 as shown in the figure.

By the way, when the discharge gas is filled in the PDP having such a structure and then the aging is performed to stabilize the discharge characteristics, as shown in FIG. The plurality of electrodes 2 arranged in an array
, One drive circuit connecting terminal 3a group is commonly connected by a clip-type aging first short bar 4,
The other drive circuit connection terminal 3b group is commonly connected by the second short bar 5. Further, to the other glass substrate 11, a group of drive circuit connecting terminals 13 of a plurality of electrodes 12 arranged at one end is connected in common by a third short bar 6.

In this state, the first short bar 4 and the second short bar 5 are electrically connected by the connecting bar 7, and a predetermined high voltage is generated by the AC high voltage generator 8 between the connecting bar 7 and the third short bar 6. By applying an AC voltage, the entire discharge display area of the display panel is discharged and aging is performed to make the discharge voltage and discharge luminance uniform and stabilize the discharge characteristics.

[Problems to be solved by the invention]

However, in the aging process of the PDP as described above, the respective electrodes 2 and 12 commonly connect their drive circuit connecting terminals 3a, 3b and 13 by the clip type short bars 4, 5 and 6. Due to the constitution, for example, when some terminals of the drive circuit connecting terminal 3a group are not electrically connected due to poor contact with the short bar 4 commonly connected, the discharge cell on the electrode is discharged. There is a fear that it will not be done. Further, when a disconnection occurs in the plurality of electrodes 2, the discharge cells formed in the electrode portion on the side cut from the connection terminal side of the electrodes become incapable of discharging, and the aging due to the discharge of the entire discharge display area is caused. There was a problem that I could not.

Furthermore, since a short bar and a connecting bar are used depending on the shape of the PDP, when a large number of different types of panels with different panel shapes are produced in response to diversifying demand for PDPs, a dedicated bar corresponding to those various types is used. It is necessary to prepare various short bars and connecting bars, which wastes these bar jigs and makes the jig management complicated.
Furthermore, there is a problem that workability is poor.

In view of the above-mentioned conventional problems, the present invention does not use a dedicated aging short bar and a connection bar,
An object of the present invention is to provide a new gas discharge display panel aging method that can ensure discharge in the entire display area by applying a general-purpose short bar to facilitate aging and easily repair electrode disconnection. Is.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention arranges a pair of substrates so as to be opposed to each other with a gas discharge space therebetween, and at least one of the substrates has a plurality of electrodes extending at both ends thereof from the opposite substrates. The electrodes are provided with a drive circuit connection terminal at one end and a repair terminal at the other end, and the electrodes are connected to the drive circuit connection terminal of an electrode at one end side of the substrate. A aging method for discharging the entire discharge display area of the gas discharge display panel in which the repairing terminals of the adjacent electrodes are displaced in the extending direction of the electrodes,
A method in which all terminals of each drive circuit connecting terminal and repair terminal at both ends of the substrate are commonly connected by a short bar, and an aging voltage is applied to all terminals at both ends commonly connected. And

(Operation)

In the present invention, the repair terminal of the electrode adjacent to the drive circuit connection terminal of the electrode on one end side of the substrate is displaced in the extending direction of the electrode and the terminal is smaller than the area of the drive circuit connection terminal. In addition, since both terminals are formed in a zigzag shape, even if the arrangement pitch of each electrode is narrowed for high-resolution display, the interval between the connection terminals provided at one end thereof is expanded, It becomes easy to electrically connect each connection terminal to the drive circuit by soldering or the like.

Moreover, in the aging step, in addition to the common connection by the clip type short bar to each drive circuit connecting terminal, the common connection can be made by the short bar on the repair terminal side. Therefore, even if there is a contact failure in any one of the short bars, power can be supplied from the other short bar.

Also, in a panel in which one drive circuit connection terminal of the electrode and the other repair terminal are led out alternately on the left and right sides of the substrate for each electrode, the drive circuit connection terminal extended to each side is extended. By simultaneously connecting the terminal and the repairing small terminal, which is led out to be shorter than the terminal, by one clip type short bar, it is possible to commonly connect all the display electrodes. Therefore, one short bar and the connecting bar can be omitted as compared with the conventional example. If two short bars are used to feed power from both ends of the electrode as in the conventional example, even if some of the electrodes have a break, the two short bars ensure reliable operation. Electrical connection can be realized.

Therefore, one short bar in which each drive circuit connection terminal and the repair terminal on one end side on the one substrate are commonly connected, and a short bar commonly connected to each drive circuit connection terminal on the other substrate By applying a predetermined AC voltage during the period, the entire display area can be surely discharged. As a result, the entire discharge display area can be efficiently aged.

Furthermore, if some of the electrodes are broken, disconnection is facilitated by connecting them with lead wires using the connection terminals and repair terminals on both sides of the cutting electrode after the aging. Can be repaired.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of an electrode structure of a PDP according to the present invention, and the same parts as those in FIG. 3 are designated by the same reference numerals.

As shown in the figure, in this embodiment, in order to widen the arrangement interval of the drive circuit connecting terminals 3 of the plurality of electrodes 2 arranged on one glass substrate 1, the drive circuit connecting terminals 3 are arranged.
Are alternately arranged on both sides of the substrate 1 as indicated by 3a and 3b. Further, the electrode end portion on the opposite side of the connection terminals 3a and 3b is located at the position where the drive circuit connection terminals 3a and 3b are arranged adjacently so as to protrude from the end portion of the other opposing substrate. The repair terminals 21a and 21b are arranged in a zigzag manner at the positions up to the arrival, and the extending portions are smaller in area than the drive circuit connecting terminals.

On one of the glass substrates 1, a plurality of electrodes 12 each having a drive circuit connecting terminal 13 at one end are formed on the one glass substrate 1 as in the conventional case.
The other glass substrate 11 in which the above are arranged constitutes a gas discharge space sealed between them, and is arranged so as to face each other such that the plurality of electrodes 2 and 12 are orthogonal to each other.

Therefore, when aging the PDP having such a structure, as shown in the plan view of FIG. 2, the drive circuit connecting terminals 3a and the repair terminals 21a arranged at both ends of the one glass substrate 1 are connected to each other. Each drive circuit connection terminal 3b and each repair terminal 21b are simultaneously connected by a general-purpose clip-type first short bar 22 and a second short bar 23 for aging, respectively, so that each drive circuit connection terminal is connected.
Electrodes 2 connected to 3a and 3b and repair terminals 21a and 21b
Even if there is a broken electrode in one place, all are surely electrically connected.

Therefore, without using a conventional connection bar, the first short bar 22 commonly connecting the drive circuit connection terminal 3a and each repair terminal 21a, or each drive circuit connection terminal 3b and each repair terminal Any one of the second short bars 23 that are commonly connected to 21b is used as the first short bar 22 and the other glass substrate in this embodiment.
Terminals for connecting each drive circuit of a plurality of electrodes 12 arranged on 11
To securely discharge the entire display area by applying a predetermined AC voltage from the AC high voltage generator 8 without using a conventional connecting bar between the clip type third short bars 24 in which 13 are commonly connected. Therefore, the entire discharge display area can be efficiently aged.

In the PDP after the aging is completed, the broken electrode in the plurality of electrodes 2 arranged on the one glass substrate 1 is for connecting the drive circuit at one end of the electrode if it is a simple cut at one place. The terminal 3a and the repair terminal 12a at the other end can be easily repaired by externally connecting them by using a lead wire.

Further, in the above-described present embodiment, an example in which a dot matrix type gas discharge display panel in which driving circuit connecting terminals are led out on three sides is arranged is described, but the present invention is limited to such an example. Instead, for example, a DC drive type or AC drive type dot matrix in which a pair of substrates in which a plurality of electrodes are arranged so as to lead out the drive circuit connection terminals only on one end side are arranged to face each other through a gas discharge space. Type gas discharge display panel, or a pair of substrates in which a plurality of electrodes are arranged so as to lead out the driving circuit connecting terminals alternately on both ends, and a pair of substrates are arranged facing each other through a gas discharge space.
Needless to say, the present invention can be applied to a drive type or AC drive type dot matrix type gas discharge display panel, and similar effects can be obtained.

〔The invention's effect〕

As is clear from the above description, according to the aging method for a gas discharge display panel of the present invention, by providing a repair terminal at the other end of each electrode having a drive circuit connection terminal at one end, dedicated aging Since it is not necessary to use a short bar for connection and a bar for connection, various bar jigs for aging can be reduced, and both ends of a plurality of electrodes can be commonly connected by a general-purpose short bar.
Even if there is a broken electrode at one place in it, electrical connection is surely made, and it is possible to easily discharge the entire display area and efficiently perform aging, etc. And reliability are improved. In addition, even in the case of a simple electrode disconnection at one place, repairing is facilitated by commonly connecting one of the drive circuit connecting terminals and the other repair terminal with a lead wire or the like, which is excellent in practical use.
