している。Generally, in a gas discharge display panel, a desired image is displayed by selecting a light emitting (discharge) cell by line-sequential scanning and employing gradation control by a subfield method. In other words, rewriting of one screen requires a maximum number of writing times for one discharge cell as many as the number of subfields. Here, particularly in a gas discharge display panel having a large display capacity, it is important to reliably generate an address discharge in a short time for good display quality. For this reason,
DC drive type gas discharge display panels with exposed discharge electrodes often use pilot discharges in addition to display discharges.
In an AC-driven gas discharge display panel in which at least a part of the discharge electrodes is covered with a dielectric, a priming discharge that makes it easier to generate an address discharge is used. The priming discharge plays a role of supplying electrons, ions, or excited atoms or molecules that facilitate the discharge into the discharge cells.

ス幅の書込み放電電圧を印加する必要がある。The occurrence of discharge involves a stochastic factor, and the time from when the address discharge voltage is applied between the discharge electrodes to when the address discharge actually occurs varies statistically. Therefore, whether or not a discharge is generated when a voltage having a predetermined amplitude is applied is stochastic, and the larger the pulse width, the more reliably the discharge is generated. The ratio between the pulse width tpw of the write discharge voltage and the probability P of occurrence of discharge is the rate at which discharge occurs within a unit time after the voltage is applied, and is determined by the state of the discharge cell when the voltage is applied. Using a constant k indicating the likelihood of occurrence of discharge, there is a relationship represented by the following equation: P = 1−exp {−k · (t pw −t f )} (Equation 1) However, in the case of t pw <t f is,
P = 0). Here, t f is a discharge delay time determined by the structure of the discharge cell and the gas composition. In the gas discharge display panel, a good display can be obtained by sufficiently setting the probability of occurrence of discharge at the time of address discharge close to 1. For this purpose, it is necessary to apply a write discharge voltage sufficiently large pulse width for a given t f and k.

As time elapses from the priming discharge,
The probability k of the occurrence of the address discharge within a unit time is reduced.
Therefore, conventionally, the discharge occurrence probability P at the time of application of the address discharge voltage in the discharge cell in which the address discharge is performed at the time when the largest time has elapsed since the priming discharge is 1
, And each address discharge time tpw is set based on this.

Was experimentally confirmed. The behavior of k in FIG.
It shows that the shorter the elapsed time from the priming discharge end time to the writing discharge voltage application time, the shorter the tpw may be, the driving method of the present invention shows that the application time tpw of the writing discharge voltage is reduced according to this relationship. Control is performed differently depending on the application time of the write discharge voltage. Thus, t pw
Is controlled individually, a sufficient discharge occurrence probability can be obtained for the entire address discharge, and the entire period required for the address discharge can be shortened.

The gas discharge display panel is configured by arranging the illustrated discharge cells in a matrix of N rows × M columns. In manufacturing the panel, first, a pair of surface discharge electrodes (row electrodes) 3 composed of mutually transparent and transparent scanning electrodes 3a and sustaining electrodes 3b are formed on the first glass substrate 1 over N rows. After covering the surface discharge electrode pair 3 with the dielectric layer 5, a magnesium oxide layer 7 is formed to obtain a first substrate.

が得られた。On the second glass substrate 2, data electrodes (column electrodes) 4 for selectively controlling discharge are formed over M columns, and after covering the data electrodes 4 with a dielectric layer 6, 9 is applied to obtain a second substrate. A grid-like partition 8 is formed on each of the dielectric layers 5 and 6. When the first substrate 1 and the second substrate are bonded to each other, the internal space is partitioned by the grid-shaped partition walls 8, and each partition is formed as a discharge cell (display cell) forming the discharge space 10.
The two substrates are bonded at an interval of 0.1 to 0.5 mm so that the electrode pair on the surface discharge side and the data electrode are orthogonal to each other. The periphery of the glass substrate was shielded from the outside by frit glass, and an airtight structure was formed except for a glass tube for gas introduction. The inside of the discharge cell is evacuated through a glass tube for gas introduction, and a discharge gas containing a rare gas as a main component is introduced and sealed, so that the gas discharge display elements are two-dimensionally arranged in a matrix in a gas discharge display. A panel was obtained.
