So, in the plasma display system of first execution mode,, therefore can not interdict the discharge space of emitting visible light by above-mentioned bus electrode 43Y, 43Z because the first next door 54a and bus electrode 43Y, 43Z overlap.And, in the plasma display system of above-mentioned first execution mode, the linking part 42b of transparency electrode 42Y, 42Z and above-mentioned bus electrode 43Y, 43Z link, and the elongated portion 42a1 of transparency electrode 42Y, 42Z, 42a2 are projected into the inside of discharge cell, therefore can improve discharging efficiency.
Fig. 7 is the discharge cell and the relevant figure of electrode structure of the plasma display system with Δ shape next door structure of second execution mode.Second execution mode shown in Figure 7 and Fig. 4 are similar to first execution mode shown in Figure 6, it is characterized in that forming depressed part in the elongated portion of transparency electrode.
As shown in Figure 7, have respectively in the inside of discharge cell: X intersects with data electrode, from the first elongated portion 42c1 of scan electrode Y elongation; With intersect with same data electrode X, and from keeping the second elongated portion 42c2 of electrode Z elongation.Wherein, the above-mentioned first elongated portion 42c1 and the second elongated portion 42c2 dispose relative to each other.
The opposite face of this first elongated portion 42c1 and the second elongated portion 42c2 is to make the spacing distance of its central portion C different with the spacing distance of end E, forms first depressed part and the second depressed part 42d1,42d2 in above-mentioned first elongated portion and the second elongated portion 42c1,42c2 respectively.
Promptly, above-mentioned first elongated portion and the second elongated portion 42c1,42c2 are as shown in Figure 7, form first depressed part and the second depressed part 42d1,42d2 at central portion C, therefore when power supply supplies to scan electrode Y respectively and keeps electrode Z, the electric field that is formed on central portion C forms weak electric field, forms highfield in the E of end.Therefore the spacing distance of above-mentioned central portion C forms the long long gap (long gap) of length, and as shown in figure 10, the shape of depressed part 42d1,42d2 is a polygonal, multiple shape such as circle.
The length in the long gap that forms between above-mentioned first depressed part and the second depressed part 42d1, the 42d2 is benchmark with resolution VGA level, has 60～180 μ m with interior length.
So, in the plasma display system of second execution mode, the elongated portion 42c1, the spacing distance between the 42c2 that have applied the transparency electrode of the voltage that is used for causing discharge further form longlyer by above-mentioned depressed part 42d1,42d2 at central portion C, therefore with elongated portion between equidistant first execution mode compare, the bigger anode region of discharging can be guaranteed, thereby contrast can be improved.
Fig. 8 is the discharge cell and the relevant figure of electrode structure of the plasma display system with Δ shape next door structure of the 3rd execution mode.The 3rd execution mode shown in Figure 8 and Fig. 4 are similar to first execution mode shown in Figure 6, it is characterized in that, the shape of data electrode that overlaps with the next door and the data electrode that overlaps with discharge space is different, with data electrode that above-mentioned discharge space overlaps in form the hole.
As shown in Figure 8, hexagonal discharge cell delimited by the first next door 54a and the second next door 54b, and the discharge cell of being delimited by above-mentioned next door 54a, 54b is configured to the Δ shape.
What form on the front substrate keeps electrode pair by scan electrode Y with keep electrode Z and constitute, and each electrode is by transparency electrode 42Y, 42Z, and bus electrode 43Y, 43Z with line width littler than the line width of this transparency electrode 42Y, 42Z constitute.
And above-mentioned transparency electrode 42Y, 42Z have shown in first execution mode: linking part 42b forms along the first next door 54a that hexagonal discharge cell delimited to the Δ shape; And elongated portion 42a1,42a2, in this linking part 42b, have the width and the elongation of regulation in above-mentioned discharge cell inside, relative in couples mutually.
In addition, the data electrode that forms on the substrate overleaf can be divided into roomy bigger X1 of width and narrow less X2 of width.At this moment, the Breadth Maximum d ' of roomy X1 of above-mentioned data electrode compares with the elongated portion 42a1 of transparency electrode, the Breadth Maximum of 42a2, be approximately its 75% to 150%, the Breadth Maximum d of narrow X2 of data electrode compare with the Breadth Maximum of elongated portion 42a1, the 42a2 of transparency electrode be approximately its 5% to 75%.
Therefore, the reason that has roomy X1 in above-mentioned data electrode is to improve the efficient of the relative discharge (address discharge) that produces between scan electrode and data electrode.In the last few years, in order to improve discharging efficiency, scan electrode and keep gaps between electrodes and form greatlyyer, when above-mentioned data electrode has above-mentioned roomy X1, even scan electrode and keep between the electrode and to form long gap, the discharge voltage that is used for discharge relatively can significantly not rise yet, and can improve driving efficient.
Roomy X1 of the data electrode of Xing Chenging can not carry out the formation in hole like this, and forms the electrode with width bigger than above-mentioned narrow X2 width, and can be used as and contain porose electrode and form between a plurality of narrow X3.
Further, the width d ' of above-mentioned roomy X1 can have different width, for example according to the flash-over characteristic in R, B, the G discharge cell at least more than one discharge cell, the width d ' of above-mentioned roomy X1 can form the order of B＞G＞R, also can form the order of B＞R＞G.
As shown in the figure, link above-mentioned a plurality of narrow X3 and when forming roomy X1, width d1, the d2 of each narrow X3 compares with the Breadth Maximum of above-mentioned transparency electrode elongated portion 42a1,42a2, be its 1% to 30%.
Form the hole between each narrow X3, the width h in this hole compare with the Breadth Maximum of above-mentioned transparency electrode elongated portion 42a1,42a2 be its 5% to 80%, compare with the width of the second next door 54b be its 50% to 110%.
If comparing with the width of the above-mentioned second next door 54b, the width h in above-mentioned hole is lower than its 50% o'clock, hole big or small too small, can't demonstrate fully the effect that reduces the data electrode fee of material, when surpassing 110%, hole big or small excessive, relatively width d1, the d2 of the narrow portion of data electrode diminish, and the relative discharging efficiency of keeping between electrode pair and the data electrode descends.
As mentioned above, in the 3rd execution mode, in discharge space, form the width d ' of data electrode bigger, in the data electrode of discharge space, form the hole afterwards, thereby reduce the scan electrode of address discharge and the distance between the active flank between the data electrode, wow and flutter (jitter) phenomenon that produces when reducing the address discharge so, can improve the discharging efficiency of Plasmia indicating panel.
Fig. 9 is the discharge cell with the plasma display system of constructing in Δ shape next door of the 4th execution mode and the figure of electrode structure.The 4th execution mode shown in Figure 9 is characterised in that, as shown in Figure 7, forms depressed part 42d1,42d2 in elongated portion 42c1, the 42c2 of transparency electrode, as shown in Figure 8, forms by roomy X1 and narrow the data electrode that X2 constitutes.
Inside at discharge cell has respectively: intersect with data electrode X, from the first elongated portion 42c1 of scan electrode Y elongation; And intersect, and from keeping the second elongated portion 42c2 of electrode Z elongation with same data electrode X.Wherein, the above-mentioned first elongated portion 42c1 and the second elongated portion 42c2 dispose relative to each other.
The opposite face of this first elongated portion 42c1 and the second elongated portion 42c2 is to make the spacing distance of its central portion C different with the spacing distance of end E, in above-mentioned first elongated portion and the second elongated portion 42c1,42c2, form first depressed part and the second depressed part 42d1,42d2 respectively, as shown in figure 10, can form variety of ways such as polygonal, circle.
Is benchmark by the gap length between the transparency electrode of above-mentioned first depressed part and the second depressed part 42d1,42d2 formation with resolution VGA level, has 60～180 μ m with interior length.
And the data electrode that forms on the back substrate is divided into roomy bigger X1 of width and narrow less X2 of width.At this moment, the Breadth Maximum of roomy X1 of above-mentioned data electrode compare with the Breadth Maximum of elongated portion 42c1, the 42c2 of transparency electrode be approximately its 75% to 150%, the Breadth Maximum of narrow X2 of data electrode compare with the Breadth Maximum of elongated portion 42c1, the 42c2 of transparency electrode be approximately its 5% to 75%.
In addition, roomy X1 of above-mentioned data electrode can not carry out the formation in hole, and forms the electrode with width bigger than above-mentioned narrow X2 width, and can be used as and contain porose electrode and form between a plurality of narrow X3.
Further, the width d ' of above-mentioned roomy X1 can have different width, for example according to the flash-over characteristic in R, B, the G discharge cell at least more than one discharge cell, the width d ' of above-mentioned roomy X1 can form the order of B＞G＞R, also can form the order of B＞R＞G.
As shown in the figure, link above-mentioned a plurality of narrow X3 and when forming roomy X1, width d1, the d2 of each narrow X3 compare with the Breadth Maximum of above-mentioned transparency electrode elongated portion 42c1,42c2 be its 1% to 30%.
