Is formed. Further, an X bus electrode 5b is formed on the X transparent electrode 5a, and a Y bus electrode 6b is formed on the Y transparent electrode 6a. Further, a dielectric layer 8a is formed so as to completely cover the X transparent electrode 5a and the X bus electrode 5b and the Y transparent electrode 6a and the Y bus electrode 6b, and a protective film (not shown) is formed on the dielectric layer 8a. MgO, etc.) 7
Are formed.

The rear glass substrate and the front glass substrate are joined in the direction of the arrow in FIG. 2 so that the protective film 7 on the front glass substrate 4 contacts the partition wall 9 on the rear glass substrate 12. . The groove between the partition walls between the pair of X electrode 5 and Y electrode 6 such that the bus electrode is on the outer side of the transparent electrode forms a discharge space 13 of one cell.

[0005] The address electrode 11 is an electrode that selectively causes a cell that performs a sustain discharge to perform a discharge. X transparent electrode 5a
The X electrode 5 including the X bus electrode 5b functions as an electrode for performing sustain discharge with the Y electrode, and the Y electrode 6 including the Y transparent electrode 6a and the Y bus electrode 6b is maintained between the Y electrode 6 and the address electrode 11. The cell that performs the discharge selectively discharges, and also functions as an electrode that performs a sustain discharge with the X electrode 5.

FIG. 3 shows a wiring diagram of an example of the above electrode. One end of the X electrode 5, which is the first electrode, is commonly connected to the outside of the cell, or is commonly connected to a plurality of blocks, and a common drive voltage is applied to each block. You. Y electrodes Y1 to Ym as second electrodes
(M is the number of Y electrodes) and address electrodes A1 to An (n is the number of address electrodes), which are third electrodes, are individually arranged one by one, so that different driving waveforms can be applied to each of them. ing.

As shown in Japanese Patent Application Laid-Open No. 6-186927, the driving sequence of a general AC type PDP is such that one field is divided into two or more subfields, and these subfields are reset. Period 1
, An address period 2, and a sustain discharge period 3.

FIG. 4 shows an embodiment of a conventional subfield driving method. The horizontal axis represents time, and the vertical axis represents Y electrodes Y1 to Ym. Here, 1 field 15
Is composed of eight subfields SF1 to SF8 and a blank 14 generated by a difference between the total time of all the subfields and one cycle period of the vertical synchronization signal Vsync.

FIG. 5 shows the structure of the subfield SFi. The subfield SFi includes a reset period 1, an address period 2, and a sustain discharge period 3, and all the subfields SFi have the same configuration.
The reset period 1 is a period for performing a reset discharge, and generates excited particles and charged particles that facilitate address discharge in the address period. The address period 2 is a period in which a cell for performing the sustain discharge is selected and the address discharge is performed between the Y electrode 6 and the address electrode 11, and thereafter, the X electrode 5
And a Y-electrode 6 causes a sustain discharge.

In the reset period 1, the charges are made uniform or the charges are erased in all the cells. Address period 2
In the sustain discharge period 3, cells for performing sustain discharge for displaying an image in the sustain discharge period 3 are sequentially subjected to address discharge for each horizontal line and selected. In the sustain discharge period 3, sustain discharge pulses having the same voltage and the same pulse width are applied to the X electrode and the Y electrode alternately at regular intervals. In the selected cell,
Sustain discharge is performed by the number of sustain discharge pulses NSF1 to NSF8 given to each subfield SF1 to SF8. For example, when the number of subfields is eight, the ratio of the number of times of sustain discharge is used as an example, and N formed by a binary code is used.
If SF1 ::: NSF8 = 1: 2: 4: 8 ::: 128, the combination of these subfields SFn is 256.

FIG. 6 shows a driving waveform in an address period 2 in one embodiment of the conventional driving method. The horizontal axis represents time, the vertical axis from top to bottom, (a) shows the voltage waveform applied to the X electrode 5,
(B) shows the voltage waveform applied to the Y1 electrode of the Y electrode 6, (c)
Shows the applied voltage waveform of the Y2 electrode of the Y electrode 6, and (d) shows the applied voltage waveform of the Ym electrode of the Y electrode 6. (E) and (f) show the voltage waveform applied to the address electrode 11. (E) shows the case where all cells in the vertical direction are selected, and (f) shows the case where the first cell and the last cell in the vertical direction are selected.

During the address period, a voltage Vxsc, for example, 60 [V] is applied to the X electrode 5 as shown in FIG. Although a voltage Vyb, for example, -70 [V] is applied to the Y electrode 6 as shown in FIGS. 6B, 6C and 6D, an address discharge for selecting a cell for performing a sustain discharge is performed. Is performed for each horizontal line, for example, 1
FIG. 6B shows the second line, and FIG. 6C shows the second line.
The voltage Vys is applied to the last line as shown in FIG.
c, for example, a scan pulse SPm of -150 [V] is sequentially applied.

At this time, as shown in FIG. 6E, a voltage Va, for example, an address pulse APm of 60 [V] is applied to the address electrode 11 during the address period 2 in correspondence with the scan pulse SPm of all the lines. Then, address electrode 1
1 in all vertical cells on the address electrodes 11 and Y
A potential difference between the electrodes 6 equal to or higher than the discharge starting voltage, for example, 210
[V] is generated, and discharge is sequentially performed between these electrodes. X
Since the potential difference between the electrode 5 and the Y electrode 6 is slightly lower than the discharge starting voltage, for example, 210 [V], immediately after this, the discharge between the address electrode 11 and the Y electrode 6 is almost simultaneously performed with the X electrode 5. The transition is made between the Y electrodes 6. Then, a discharge is performed between the X electrode 5 and the Y electrode 6, and wall charges required for the sustain discharge are sequentially formed on the surfaces of the MgO films on the X electrode 5 and the Y electrode 6, respectively. Hereinafter, these two discharges are collectively referred to as an address discharge.

As another example, when an address pulse APm as shown in FIG. 6 (f) is applied, address discharge occurs only in cells on the address electrode 11 corresponding to the first line and the last line. Done.

[0015]

The conventional address period 2

For this reason, as the number of cells increases as the definition of the panel increases, the address period becomes longer, and the number of address discharges increases.
A cell in which the address discharge is performed later has a larger amount of accumulated charge, a potential difference between the address electrode 11 and the Y electrode 6 becomes smaller, and it becomes difficult to perform the address discharge. Also,
In a cell in which the address discharge is performed late in the address period, the excited particles and the charged particles generated in the reset period attenuate over time, so that it is difficult to perform the address discharge. As a result, in a high-definition panel, non-lighted cells in which address discharge is not performed and sustain discharge is not performed are likely to occur, causing a problem that an address voltage operation margin is narrowed when driving the entire panel.

An object of the present invention is to eliminate the non-lighted cells, expand the address operation margin, and provide high uniformity and high quality over the entire panel by reliably performing address discharge on the entire panel even in a high definition display.
