Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for writing in a discharge transition channel consisting of a regular array of discharge transition cells regularly configured with multi-phase band-like transition electrodes. The transition of a charge transition type gas discharge panel is characterized in that a desired display pattern is obtained by injecting display data as a charge from a write electrode and moving it by a transition electrode, while erasing unnecessary display data by an erase electrode. This relates to electrode structure.

A conventional charge transition type gas discharge panel generally has a structure shown in FIG. FIG. 1 shows a cross section along a transition channel of a charge transition type gas discharge panel.

The charge transition type gas discharge panel shown in this figure displays the charge input from the write electrode 3 by discharging it through the transition electrodes 4 and 5. Therefore, the margin of this transition operation directly affects the charge transition type gas discharge. Affects the operating margin of the panel. The conventional charge transition type gas discharge panel has a narrow transition operation margin of about IOV to 15V, and has not yet been put to practical use.

Therefore, the present invention clarifies the optimal structural conditions of the electrode width and pitch of the charge transition electrode of the charge transition type gas discharge panel,
It is an object of the present invention to provide a charge transition type gas discharge panel having a transition electrode structure that can realize display over a wide range of pitches.

According to the present invention, a charge transition type gas discharge panel is characterized in that it has a structure that satisfies the conditional expression taπ1−〇−, where W is the width of the transition electrode, P is the electrode pitch, and d is the discharge gap. is obtained.

In this patent, it is assumed that the charge transition operation of the charge transition type gas discharge panel consists of a three-stage process, and the parameter θl indicates the intensity of the discharge occurring in each process.

An attempt was made to find a conditional expression that determines the optimal dimension of the transition electrode depending on the definition of θ2.

The operation process of the above charge transition will be explained below.

First stage of charge transition operation; display data is held in the form of discharge maintenance.
A discharge is generated between the end of the n-th transition electrode at C and the end of the next (n+1)-th transition electrode, and display data is transferred to the n]-1st transition electrode.

Second stage: This is a transition stage in which the discharge generated in the first stage grows over the entire surface of the transition electrode and combines the first stage discharge with the subsequent third stage discharge.

Third stage: A discharge similar to that in the first stage is generated at the 11th+1st and +1+2nd transition electrodes, and display data is transferred to the 11th+2nd electrodes.

In the charge transition type gas discharge panel, the transition operation is realized only when the three stages described above are organically combined.

Therefore, in order for the charge transition type gas discharge panel to have a sufficient operating margin for practical use, it is necessary to find an optimum value for the combination of the above three stages. For this reason, the parameter θ1 shown below. θ, and manufacture charge transition type gas discharge panels with various transition electrode structures,
The relationship between operating margin and transition electrode structure is analyzed.

Below is the parameter θ1. The definition of θ is given below.

(Figure 2 is shown schematically.) Parameter θ1. Definition of θ, θ, is the angle from one end of a transition electrode to the end of the next transition electrode.

θ,: The angle at which the end of the transition electrode is viewed from a position on the center line of the transition electrode and separated by the distance of the discharge gap length.

FIG. 3 shows the results of analysis using the parameters θ1 and 42 defined as above. The difference between the maximum transition voltage Vsmax and the minimum transition voltage Vsmin (Vsm
axVsmin) is the operating margin of the charge transition type gas discharge panel. It can be seen from the figure that the operating margin tends to decrease as θ weight/θ2 increases.

When considering the conditions under which a charge transition type gas discharge panel can be put to practical use, an operating margin of at least 20 cm is required due to requirements such as drive breakdown voltage fluctuations and life characteristics. Therefore, if we look at the region that satisfies the operating margin of 20 V or more from FIG. 9, we find that it is the region expressed by the conditional expressions θ1/θ, -H1,5.

If this is replaced by the above-mentioned transition electrode width W, electrode pitch P, and discharge gap d, the following conditional expression is obtained.

12d tan w In this patent, for example, P=0.
6mmr W=0.2mrue C1=0.25*+x
