Description

[Detailed Description of the Invention] [Summary] Regarding a dot matrix type gas discharge display panel having an electrode terminal structure suitable for aging or repairing broken electrodes, the present invention relates to a dot matrix type gas discharge display panel that has an electrode terminal structure suitable for aging or repairing broken electrodes. A pair of substrates are arranged facing each other with a gas discharge space interposed therebetween, and at least one of the substrates is arranged facing each other with a gas discharge space in between. In a panel configuration in which a plurality of electrodes each having a drive circuit connection terminal at one end are arranged on the substrate facing surface of the substrate, the other end of the plurality of electrodes is made to protrude beyond the edge of the opposing substrate. It is configured as a repair terminal.

[Industrial application field]

The present invention relates to a dot matrix type gas discharge display panel having an electrode terminal structure suitable for repairing aging or electrode breakage.

In recent years, the display shapes of dot matrix type gas discharge display panels have become more diverse as display devices to which they are applied have diversified, and display panels of various sizes have been used, and high-mix low-volume production is also required in manufacturing. There is.

Therefore, in the aging process in manufacturing the gas discharge display panel, the versatility of jigs such as aging short bars that commonly connect multiple electrode terminals of the display panel is increased, and the number of bar jigs is reduced. There is a need for a gas discharge display panel having an electrode terminal structure that improves process efficiency and allows for easy repair of disconnected electrodes.

[Conventional technology]

Conventionally, in dot matrix type gas discharge display panels (hereinafter abbreviated as FDP), the number of display electrodes has been increased to meet the demand for higher resolution, and the pitch of the electrodes has been narrowed. Since the spacing between the connection terminals provided at one end of the electrode is inevitably narrowed, making connection with the drive circuit difficult, the connection terminals 3 are alternately led out to both ends of the glass substrate 1, as shown in FIG. A configuration is adopted in which the spacing between adjacent terminals is widened and the width of each terminal is widened.

Note that the terminal group of the electrode 12 group on the other glass substrate 11, which is disposed opposite to this glass substrate 1 with a gas discharge space in between, may be arranged in the above-mentioned arrangement or as shown in FIG. 3, depending on the size of the display screen. It is led out only to one side of the substrate 11.

By the way, when aging is performed to stabilize the discharge characteristics after filling a discharge gas in a PDP with such a structure, as shown in FIG. For example, one group of drive circuit connection terminals 38 of the plurality of electrodes 2 arranged in a row is commonly connected by a clip-type aging shoulder 4,
The other group of drive circuit connection terminals 3b are commonly connected by a second iodo bar 5. Further, to the other glass substrate 11, a group of drive circuit connection terminals 13 of a plurality of electrodes 12 aligned on one side edge are commonly connected by a third short bar 6.

In this state, the first shodoper 4 and the second iodopar 5 are electrically connected by the connecting bar 7, and
A predetermined AC voltage is applied between the connection bar 7 and the third shorting bar 6 by the AC high voltage generator 8 to discharge the entire discharge display area of the display panel to perform aging, thereby changing the discharge voltage and discharge brightness. Efforts are being made to equalize and stabilize these discharge characteristics.

[Problem to be solved by the invention]

However, in the FDP aging process as described above, each of the electrodes 2, 12 groups, and their drive circuit connection terminals 3a, 3b, and 13 groups are commonly connected by clip-type short bars 4, 5, and 6, respectively. For example, a short bar 4. which some terminals of the drive circuit connection terminal group 3a are commonly connected to. If there is no electrical connection due to poor contact with the electrode, there is a risk that the discharge cells on that electrode will not be discharged. In addition, if a disconnection occurs in the plurality of electrodes 2, the discharge cell formed by the electrode part on the side disconnected from the connection terminal side of the electrode becomes unable to discharge, and aging due to discharge in the entire discharge display area becomes impossible. The problem was that it couldn't be done.

Furthermore, since special short bars and connection bars are used depending on the shape of the FDP, when performing high-mix low-volume production with different panel shapes due to diversifying demand for FDPs, special short bars and connection bars are used to accommodate the wide variety of FDPs. Various short bars and connection bars must be prepared, which causes problems such as wasting of these bar jigs, complicating the management of the jigs, and poor workability.

In view of the above-mentioned conventional problems, the present invention makes aging easier by ensuring discharge in the entire display area by applying a general-purpose short bar without using a dedicated aging short bar and connection bar, and It is an object of the present invention to provide a novel gas discharge display panel in which disconnection of electrodes can be easily repaired.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention arranges a pair of substrates facing each other with a gas discharge space interposed therebetween, and a plurality of electrodes each having a drive circuit connection terminal at one end are arranged on the opposite surface of at least one of the substrates. In this panel configuration, the other ends of the plurality of electrodes are made to protrude beyond the ends of the opposing substrates to serve as repair terminals.

[For production]

In the present invention, if the end of each electrode opposite to the end on which the drive circuit connection terminal is provided is made to protrude beyond the end surface of the opposite substrate and is used as a repair terminal, each drive circuit connection terminal is In addition to the common connection using the clip-type short bar, it is also possible to make a common connection using the short bar on the repair terminal side. Therefore, even if there is a poor contact in either one of the short bars, power can be supplied from the other short bar.

In addition, in a panel where electrodes are alternately led out on both the left and right sides, the drive circuit connection terminal and the pair small terminal led out on each side can be connected simultaneously using a single clip-type short bar. , it becomes possible to connect all display electrodes in common. Therefore, compared to the conventional example, one shortener and a connecting bar can be omitted. In addition, if the structure is configured such that two short bars are used to supply power from both ends of the electrodes as in the conventional example, even if some of the electrodes are disconnected, the two short bars will ensure that the power is supplied from both ends of the electrodes. Electrical connection can be achieved.

Therefore, one short bar commonly connects each drive circuit connection terminal and pair terminal on one end side of the one board, and one short bar commonly connects each drive circuit connection terminal on the other board. By applying a predetermined alternating current voltage during this period, the entire display area can be reliably discharged. As a result, it becomes possible to efficiently age the entire discharge display area.

Furthermore, if some electrodes are disconnected, the disconnection can be easily removed by using the connection terminals and pair terminals on both sides of the disconnected electrodes and connecting them with lead wires, etc. after the aging process. can be repaired.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing an example of the electrode configuration of an FDP according to the present invention, and parts equivalent to those in FIG. 3 are given the same reference numerals.

As shown in the figure, in this embodiment, in order to widen the spacing between the drive circuit connection terminals 3 of the plurality of electrodes 2 arranged on one glass substrate l, the drive circuit connection terminals 3 are ,
They are arranged alternately at both ends of the substrate 1 as shown at 38 and 3b. Further, the electrode end portions on the opposite side of the connection terminals 3a and 3b are made to protrude beyond the end of the other opposing board to the arrangement position of the drive circuit connection terminals 3a and 3b arranged next to each other. The protruding portions thereof are used as repair terminals 21a and 21b, respectively.

Then, on one glass substrate 1, a plurality of electrodes 1 each having a drive circuit connection terminal 13 at one end are disposed as in the conventional case.
The other glass substrate 11 on which the electrodes 2 are arranged constitutes a sealed gas discharge space therebetween, and each of the plurality of electrodes 2
．． 12 are arranged facing each other so as to be perpendicular to each other.

Therefore, when aging an FDP with such a configuration, each drive circuit connection terminal 3a and each repair terminal 21a provided at both ends of the one glass substrate 1, as shown in the plan view of FIG. By simultaneously connecting each drive circuit connection terminal 3b and each repair terminal 21b with a general-purpose aging clip-type first show door 22 and second second show door 23, each drive circuit connection terminal 3a and each repair terminal 21b are connected simultaneously. All electrodes 2 connected to the pair terminals 21a and 21b are electrically connected even if there is a disconnected electrode among them.

Therefore, without using a conventional connection bar, the first shodper 22 commonly connects each drive circuit connection terminal 3a and each repair terminal 21a, or each drive circuit connection terminal 3b and each repair terminal. In this embodiment, the short bar of one of the second iodopars 23 commonly connected to the second iodopar 21b is connected to the second short bar 22 and each drive circuit of the plurality of electrodes 12 disposed on the other glass substrate 11. By applying a predetermined AC voltage from the AC high voltage generator 8 between the clip-type third shorters 24 to which the connection terminals 13 are commonly connected, without using a conventional connection bar, the entire display area can be reliably covered. This allows the entire discharge display area to be efficiently aged.

In addition, if the broken electrode among the plurality of electrodes 2 arranged on one glass substrate 1 in the FDP after aging is completed, if it is a simple cut in one place, it is necessary to connect one end of the electrode to the drive circuit. Terminal 3a and other end glue pair terminal 21a
This can be easily repaired by connecting them externally using lead wires.

Further, in the above embodiment, an example has been described in which a dot matrix type gas discharge display panel in which drive circuit connection terminals are led out and arranged on three sides is used, but the present invention is limited to such an example. For example, it is a DC drive type or AC drive type dot in which a pair of substrates on which a plurality of electrodes are arranged are placed facing each other across a gas discharge space so that the drive circuit connection terminal is led out only on one end side. A matrix type gas discharge display panel, or a DC drive type in which a pair of substrates on which a plurality of electrodes are arranged so as to alternately lead out drive circuit connection terminals on both ends are arranged facing each other across a gas discharge space, or Needless to say, the present invention can also be applied to an AC-driven dot matrix type gas discharge display panel, and similar effects can be obtained.

〔Effect of the invention〕

As is clear from the above description, according to the gas discharge display panel according to the present invention, by providing a repair terminal at the other end of each electrode having a drive circuit connection terminal at one end, a dedicated aging short bar is provided. There is no need to use connection bars and various bar jigs for aging can be reduced, and both ends of multiple electrodes can be commonly connected using a general-purpose short bar, so even if there is a broken electrode, Even if there is a problem, the electrical connection can be made reliably, and the entire display area can be easily discharged and aged efficiently, improving workability and confidence in the aging process. Furthermore, it is possible to easily repair a simple disconnection of an electrode at one location, which has a practical effect.
