Abstract

PURPOSE:To obtain a surface discharge type gas discharge panel that can acquire a high write operation margin by arranging a discharge suppressing stray conductor that is insulated from any electrode at least on one discharge holding electrode on the reverse side of a side adjacent to the write electrode of the protrusion section of individual teeth of a comb. A discharge holding cell Sc is comprised by arranging. CONSTITUTION:Discharge holding electrodes 32 and 33 with individual adjacent and paired protrusion sections of the teeth of a comb 32a and 33a on a lower side glass substrate 31. In addition, a discharge suppressing stray conductor 39 that is insulated from any electrode is arranged on the respective paired electrode holding electrodes 32 and 33 between a write electrode 35 and the write electrode 35 at a side on which the electrode is greatly separated from the protrusion sections 32a and 33a of the respective discharge holding electrodes 32 and 33 through a thick film dielectric layer 34 made of low melting point glass and such on the top. Since the stray conductor 39 has high electric capacity, a wall charge is prevented from spreading over the stray conductor 39 and from extending on the surface of the dielectric layer 34 corresponding to the discharge holding cell Sc at the stray conductor 39 side.

In particular, the present invention relates to a new panel structure that can widen the write operation margin of a surface discharge type gas discharge panel that is composed of a pair of adjacent sustain electrodes and write electrodes.

書込み動作マージンが広くとれない問題がある。In this type of gas discharge panel, a pair of substrates are placed facing each other with a discharge gas filled space in between, and the electrodes constituting the discharge cells are placed on one of the substrates and covered with a dielectric layer. As a result, the requirement for gap accuracy in the gas discharge space between the pair of substrates is significantly relaxed, and
Another advantage is that an ultraviolet ray-reducing phosphor is attached to the inner surface of the other front glass substrate for the cover relative to one of the substrates constituting the discharge cell, thereby making it easy to create a multicolor fluorescent display. However, on the other hand, since the display discharge cells are formed by spreading by lateral discharge along the surface direction of the substrate, there is a problem that generally a wide write operation margin cannot be secured.

This write discharge causes a wall charge to be generated on the surface of the dielectric layer 4 corresponding to the write discharge cell, and the wall charge is accumulated in a form extending to the surface of the dielectric layer N4 corresponding to the adjacent discharge sustaining cell Sc. . Therefore, all pairs of discharge sustaining electrodes 2, 3
By applying a predetermined discharge sustaining voltage Vs between
In order to maintain the discharge by continuing the write discharge only in the discharge sustaining cell Sc which has received the inflow of wall charges, a system is adopted in which the discharge cells are functionally separated.
This prevents the localized concentration of the discharge current at the electrode portion of the ik electrode.

放電パネルが要望されている。However, in the conventional method described above, the operating margin of the write voltage applied to the discharge sustaining electrode 2 and the write electrode is small, so the write voltage must be high enough to generate a predetermined write discharge. When a write discharge is applied, the write discharge in the write discharge cell holder spreads not only to nearby discharge sustaining cells Sc but also to distant discharge sustaining cells Sc, and a write discharge is generated in each of these near and far discharge sustaining cells Sc. Therefore, there is an inconvenience that it is not possible to selectively inherit the writing discharge to the desired discharge sustaining cell Sc and sustain the discharge. For these reasons, there is a demand for a surface discharge type gas discharge panel that can provide a large write operation margin.

When a sufficiently high write voltage is applied to the electrodes 35 to generate a predetermined write discharge, these electrodes;) 2 and 3
A write discharge is generated in the write discharge cell Wc formed at the intersection of the lines 5 and 5. Simultaneously with this write discharge, a perfect charge was generated on the surface of the dielectric layer 34 corresponding to the write discharge cell Wc, and the wall electrode 7ii1 extended to the surface of the dielectric layer 34 corresponding to the adjacent discharge sustaining cell Sc. The floating conductor 39 is placed in the discharge suppressor 1.
The dielectric layer corresponding to the discharge sustaining cell Sc of i'l naturally spreads and extends to the surface of I4, but when this charge reaches the floating conductor 39, it 39
Since 1.5 of the floating body 39 is accumulated in the eson of the floating body 39, the m i't:f spreads beyond this floating body 39, and the ρ floating body 39 is expanded. In 39 cases, the discharge sustaining cells Sr are prevented from extending to the surface of the corresponding dielectric layer 34. Therefore, by continuing to apply a predetermined voltage νS between all the pairs of discharge sustaining electrodes 32 and 33, the discharge sustaining cells S receiving the inflow of wall charges are
The discharge is continued in the form of S++ continuing the write discharge only at c.
) It becomes possible to cause the write discharge to be reliably received in the charge sustaining cell Sc and to sustain the discharge.

It has excellent advantages such as being able to reliably inherit writing discharge to the desired discharge sustaining cell Sc and shifting the discharge sustain, and can be applied to this type of surface discharge type gas discharge panel to improve manufacturing yield. In addition to increasing the voltage by 1:1 J, there are significant practical consequences, such as increasing the margin of voltage setting of the discharge drive power source used for the gas discharge panel.
