Abstract

PURPOSE:To obtain a discharge transition type gas discharge panel serviceable for practical use by putting the positional relation of the charge transition electrodes with the write electrode to the most suitable condition. CONSTITUTION:When defining the terminal of the write electrode 3 side of the transition electrodes 4 and 5 forming a write discharge cell as A, the terminal of the delete electrode 6 side as B and the terminal on the side of the transition electrodes 4 and 5 of the write electrode 3 as W, the constitution shall be so that the angle theta formed by WAB may not exceed 135 deg., while the write electrode 3 may not face the transition electrode 5 exceeding 1/2 of the transition electrode width. Thereby, a charge transition type gas discharge panel exceeding the write motion margin 20V can be obtained and put to practical use.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to an electromagnetic wave generator which has a regular configuration of multiphase band-shaped transition electrodes.
i! Writing into a discharge transition channel consisting of a regular array of transition cells A desired display pattern is created by injecting display data as a charge from a write electrode provided at one end of the channel constituting the discharge cell and moving it by the transition electrode. The present invention relates to a dead discharge cell of a charge transition type gas discharge panel having an erase unit for erasing unnecessary display data while obtaining the data.

A conventional charge transition type gas discharge panel generally has a structure shown in FIG. FIG. 1 shows a cross section of a transition channel I/r of a charge transition type gas discharge panel. The charge displacement type scum discharge panel shown in this figure displays the charge leaked from the write electrode 3 by discharging and transferring it to the transition electrodes 4 and 5. Therefore, when writing, the charge is removed from the pole 3. The discharge margin at 1fji between the write electrode 3 and the transition electrode a1 during injection directly influences the operating margin of the charge transition type gas discharge panel. The margin of the above-mentioned pumping operation is conventionally narrow at 10 to 15 V, and it has not yet been put to practical use.

Therefore, an object of the present invention is to find the optimum conditions for the positional relationship between the charge transition electrode and the write electrode of a charge transfer type gas discharge panel, and to provide a charge transition type gas discharge panel that can be put to practical use.

According to the present invention, when A is the insertion electrode opening of the transition electrode forming a write discharge cell, B is the end on the erase electrode side, and W is the end of the write electrode, (WAB≦135° and write A charge transition type gas panel can be obtained in which the electrode does not face the transition electrode by more than 1/2 of the width of the transition electrode.

In the present invention, the writing electrode W and the transition shown in FIG. 4th section l・Dynon John θ of the schematic diagram shown
We fabricated a charge transition type gas discharge panel with a structure in which d and d were varied in various ways, and attempted to determine the relationship between the writing voltage, the optimal position fr of the sliding door and the transition electrode.

The results are shown in FIGS. 3 and 4. As shown in FIG. 3, as the angle θ between the unraveling electrode and the transition electrode increases, the write voltage Vw increases, while the operating margin (Vsmax −Vsmin) of the charge transition type gas discharge panel increases.
) does not change. However, this increase in write voltage is not a desirable phenomenon for the drive circuit of the charge transition type gas discharge panel.

Generally, the maximum rating of an inexpensive and practical driving transistor is 220V for writing. Therefore, when the angle θ is θ≧13, the writing voltage is 220 V or more, which is not practical. Also, from FIG. 4, as the opposing portion d between the writing electrode and the transition electrode increases, It is observed that the write operation margin decreases.

Considering the conditions for putting a charge transition type gas discharge panel into practical use, an operating margin of at least 20 V is required due to drive voltage fluctuations, life characteristics, and other requirements.

From this, it can be seen that the area that can be practically compressed is d≦÷. Here, W indicates the width of the transition electrode, and d indicates the opposing portion of the write electrode and the transition electrode.

From the above, it has been found that the positional relationship between the write electrode and the transition electrode, expressed using the above-mentioned θ and d, is optimal when the following conditional expression is satisfied.

〉 0 θ: 135 d≦÷ Therefore, in this patent, for example, θ= that satisfies the above conditions.
A charge transition type gas discharge panel having a structure of 60° transition electrode pitch of 0.6 mytr + transition electrode width of 0.2 m was fabricated. As a result, the write operation margin is 25
It was possible to obtain a charge transition type gas discharge panel of V or higher.

As explained above, by following the positional relationship between the write electrode and the transition electrode according to this patent, it was possible to obtain a charge transition type gas discharge panel with a write operation margin of 20 V or more, and it was possible to put it into practical use.
