Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-shifting gas discharge panel, and more particularly to a self-shifting gas discharge panel with complete erasure in the final portion of the shift.

For example, as shown in FIG. 1, a self-shifting gas discharge panel has electrodes yi (j=1, 2, 3, . . . )
1 and electrodes ai, bi, ci, di (i: 1, 2, ......
n) were arranged to face each other orthogonally through a discharge gas filled space, a dielectric layer such as low melting point glass was provided on each electrode, and electrodes ai to di were periodically connected to bus lines A to D, respectively. When shifting the discharge spot in the direction of the arrow, as shown in FIG.
The shift voltage shown in is applied. Then, when the written content is shifted to a predetermined position, if a shift voltage is continuously applied only to bus lines C and D at the same time, static display can be performed by the discharge point between electrodes ci and dj and electrode yj. . That is, it will be displayed in the state shown by the circle in FIG. Also, if you continue the self-shift operation,
The discharge spot that has reached electrode dn will be erased the next time a shift voltage is applied to bus line A, but the electric field distribution at this final electrode dn will be different from the electric field in other parts of the panel. The distribution will be significantly different from the distribution, and since there is no place to shift the discharge spot after the final electrode dn, the wall charge at the discharge point on the final electrode dn cannot be sufficiently erased. Therefore, if static display is performed when the discharge spot is not shifted to the discharge point on the electrodes cn, dn, a discharge spot will be generated at the discharge point on the electrodes cn, dn because the previous wall charge remains. This will result in incorrect display. The present invention is a novel invention that improves the above-mentioned drawbacks, and its purpose is to prevent erroneous display from occurring even when the final electrode of self-shifting is used as a display electrode for static display. It is in.

Examples will be described in detail below. FIG. 3 is an explanatory diagram of an embodiment of the present invention, and the same reference numerals as in FIG. 1 indicate the same parts.

When performing a static display after self-shift operation as described above,
If the final electrode dn of self-shifting becomes an electrode for static display by intermittently applying a voltage to bus lines C and D, add an electrode ao that is not for static display, or an electrode bo as shown by the dotted line. It is something to do. Therefore, when a shift voltage is applied to the bus line D and the discharge spot is shifted to the discharge point on the electrode dn, when a shift voltage is applied to the bus line A, the discharge spot is shifted to the discharge point on the electrode ao. , the wall charge at the discharge point on the electrode dn is completely erased, and the electric field distribution of the electrode blood becomes almost the same as that of other parts due to the presence of the electrodes ao and cn on both sides thereof.
In other words, the discharge point on the final electrode dn of self-shift has the same characteristics as the discharge points in other parts, so that it can not only perform self-shift operation but also perform static display by continuously applying voltage to bus lines C and D. This also eliminates the possibility of erroneous display when performing this function. Note that the added electrodes ao or bo will be the final electrodes for actual self-shifting, but the discharge points on these electrodes ao and bo are not for static display, so even if there is residual wall charge, it will not affect static display in any way. It has no effect on

Further, when applying voltage only to the bus line D in the case of static display, it is also possible to further add an electrode connected to the bus line C. Also, in the case where there are three bus bars, it is sufficient to similarly add an electrode connected to the bus bar to which no voltage is applied during static display. As explained above, the present invention provides N bus lines (N is an integer of 2 or more) facing the gas discharge space,
For example, electrodes ai to di connected periodically to bus lines A to D
A shift voltage is sequentially applied to the N busbars to shift the discharge spot, and a specific M busbar (ISM-N-1) among the N busbars is applied, for example, busbar C.
, D in a self-shift type gas discharge panel that displays a stationary display by continuously applying a voltage to the terminals dn and dn. , for example, by arranging an electrode connected to the bus line A, and next to the final electrode for static display, an electrode connected to the bus bar connected to an electrode other than that for static display is provided. , it becomes possible to further shift the discharge spot from the final electrode for static display, and it becomes possible to ensure the disappearance of the wall charge at the discharge point on the final electrode for static display.

This has the advantage that it is possible to prevent a plot display during static display. Also, since a dielectric layer is provided on the electrode provided next to the final electrode for static display in the same way as on other electrodes, the process for forming the transfer body layer is not particularly complicated. do not have.
