Five, embodiment

Below, lift preferred embodiment, and conjunction with figs. is described in detail as follows.

Fig. 6 is the PDP structural representation among the present invention the 1st embodiment.The structure of PDP in the present embodiment has been improved a plurality of distributions of keeping electrode (X) and scan electrode (Y) that are arranged on the upper plate 210, and is different with prior art among Fig. 5, repeatedly a pair of electrode (X) and a pair of scan electrode (Y) kept of arranged alternate.That is, adjacent discharge cell up and down (cell) is symmetrical, top discharge cell (cell) keep electrode (X) and below discharge cell (cell), be not scan electrode (Y) but to keep electrode (X) adjacent.

The structure of this present embodiment and keeps in the upper plate 110 that electrode (X) and scan electrode (Y) merely replace repeatedly, and illustrated among Fig. 5, the arrangement of keeping electrode (X) and scan electrode (Y) of PDP of the prior art is obviously different.

Again, form on the lower plate 120, the interlayer of dividing discharge cell (cell) is for all discharge cells (cell), form with vertical interlayer 123 and horizontal interlayer 126, with all discharge cells (cell) be enclosed type (enclosed type), the PDP structure difference of prior art among Fig. 5, only at the horizontal interlayer 226 of the right arranged beneath of adjacent scan electrode (Y), horizontal interlayer is not arranged in right below and keep electrode (X) in the present embodiment.

In sum, keep no horizontal interlayer between the affiliated separately discharge cell up and down (cell) of electrode (X) for adjacent two, form open space, vertical illustrated (stripe) type spacer structure among the structure of interlayer 123 and Fig. 1, prior art such as illustrated lattice type spacer structure is similar among Fig. 5.As the prior art among Fig. 5, horizontal interlayer 226 is set between adjacent two scan electrodes (Y) again.

Fig. 7 and Fig. 8 are respectively among above-mentioned Fig. 5, have the PDP of the lattice type spacer structure of prior art, with the PDP floor map of the spacer structure with the present invention the 1st embodiment.As mentioned above, illustrated among Fig. 8, the PDP in the present embodiment has arranged that repeatedly adjacent two are kept electrode (X) and adjacent two scan electrodes (Y), keep between electrode (X) for adjacent two horizontal interlayer is not set.

Fig. 9 to Figure 11 is the diagram that the PDP structure of the 1st embodiment in the invention described above is compared with illustrated PDP structure of the prior art among Fig. 1 and Fig. 5.Fig. 9 to Figure 11 all shown with the profile status of keeping the direction cutting panel that electrode (X) and scan electrode (Y) intersect vertically.

Fig. 9 is the diagram of bar (stripe) the type spacer structure about Fig. 1.Keeping during the interval (S) as shown in Figure 3 kept pulse (sustain pulse) what keep that electrode (X) and scan electrode (Y) go up alternately negative adding+Vs size, keeps discharge repeatedly.Therefore, as shown in Figure 9, keep the potential difference of between electrode (X) and scan electrode (Y) generation being kept voltage and wall voltage (wallvoltage) addition in the same discharge cell (cell), and respectively belong to adjacent keeping between electrode (X) and scan electrode (Y) of discharge cell (cell) and also will produce potential difference, if the spacing between discharge cell (cell) is big inadequately, then the electric field (electric field) that forms between two discharge cells (cell) will cause misplacing, because above-mentioned electric field, to promote charged particle to enter adjacent cell (cell), promote crosstalk (cross-talk) between cell (cell).

As shown in figure 10, Fig. 5 etc., in the lattice type spacer structure of prior art, laterally interlayer 126 has intercepted adjacent discharge cell (cell), therefore, has certain potential difference even belong to keeping between electrode (X) and scan electrode (Y) of other discharge cell (cell), can not produce yet and misplace electricity or crosstalk (cross-talk), therefore, in the very narrow high definition panel of the spacing between discharge cell (cell), extensively adopt above-mentioned lattice type spacer structure again.

But, spacing between discharge cell (cell) is originally with regard in the very narrow high definition panel construction, along with importing horizontal interlayer 126, as shown in figure 10, its discharge space will be narrower, therefore, the reduction of guiding discharge efficient and power-efficient falls in the loss of the charged particle on the horizontal interlayer 126 adjacent with plasma, laterally interlayer 126 will weaken the electric field between discharge cell (cell), but still there is a potential difference, therefore, promote charged particle to enter horizontal interlayer 126, strengthened the loss of charged particle.

On the other hand, illustrated among Figure 11, in the spacer structure of the present invention the 1st embodiment, belong to that two of adjacent two discharge cells (cell) keep electrode (X) and two scan electrodes (Y) are adjacent separately.Therefore, keep interdischarge interval (S) among Fig. 3, each is thought highly of oneself and adds identical current potential to keep electrode (X) and scan electrode (Y), does not therefore have potential difference, and the electric field between discharge cell (cell) significantly reduces.

Therefore, in the structure of the present invention the 1st embodiment, portion arranges horizontal interlayer 226 between electrode (X) even keep at adjacent two, misplaces electricity or the possibility of crosstalk (cross-talk) also significantly reduces.Again, do not arrange horizontal interlayer, can reduce the loss of charged particle on the interlayer, can improve discharging efficiency and power-efficient in adjacent keeping between electrode (X).

At this moment, misplace electricity or crosstalk (cross-talk) between the adjacent cell (cell) that causes for the diffusion that suppresses priming particle (priming particle), two adjacent spacings of keeping between electrode (X) should reach more than about 80um.

Adjacent two scan electrodes (Y), (S) also added identical current potential by negative during the keeping in Fig. 3, therefore there is not potential difference, but during (W) between positioning area, because bearing, moment adds scanning impulse, therefore each scan electrode (Y) is selected successively with the run in form of (line by line) of row, along with negative being added on the keeper electrode of position pulse that will be synchronous with above-mentioned scanning impulse, will note down data in the discharge cell (cell) that links to each other with the row of respective scanned.Therefore, keep can not bear in two scan electrodes (Y) adjacent during the interval and add identical current potential.Therefore, between adjacent two scan electrodes (Y), as shown in figure 11, arrange horizontal interlayer 226, prevent to misplace crosstalk (cross-talk) between electricity and discharge cell (cell).

Figure 12 is the schematic diagram of PDP panel construction among the 2nd embodiment of the present invention.Among illustrated the 2nd embodiment, horizontal interlayer 327 is also arranged in adjacent keeping between electrode (X), and the height of above-mentioned horizontal interlayer 327 (h2) is lower than the height (h1) of the horizontal interlayer (326) between adjacent scan electrode (Y).

Like this, neither crosstalk (cross-talk) can also obtain maximum power-efficient, can adjust the height of horizontal interlayer (327) in optimum range according to discharge cell (cell) spacing that is fit to the panel specification.Again, identical with the lattice type spacer structure of Fig. 5 because have horizontal interlayer 327, the spray area of fluorophor strengthens, and can improve twice.

When Figure 13 is to use PDP structure among the present invention, the layout plan of black matrix (black matrix).

Adjacent two scan electrodes (Y) and two keep between electrode (X) with having or not of separately interlayer irrelevant, on upper plate 210, suitably arrange black matrix (black matrix) (B), prevent from the light that exposes the slit between discharge cell (cell) to obtain good contrast with this.At this moment, black matrix (black matrix) (B) is used common materials such as the resin material that contains black pigment or black belt, is arranged on the upper plate.

In sum; though the present invention about the high-definition plasma display panel structure that enlarges discharge space and the plasma display system that utilizes this technology with preferred embodiment openly as above; right its is not in order to limit the present invention; any those skilled in the art; under the situation that does not break away from the spirit and scope of the present invention; can carry out various changes and modification, so protection scope of the present invention is as the criterion when looking the claim restricted portion that is proposed.

Use the technology among the present invention to obtain, can prevent crosstalk (cross-talk) between adjacent cell (cell), reduce the loss of charged particle, improve discharging efficiency and power-efficient, have the Plasmia indicating panel of satisfactory texture.

Especially, the present invention can use effectively in high-definition plasma body display floater, uses the panel construction among the present invention, can improve the layout of arrangement of electrodes and horizontal interlayer, increases discharge space as far as possible.

Again, use the horizontal spacer structure such as difference among the present invention the 2nd embodiment, will get the interior to the limit discharge space that increases, the Plasmia indicating panel of sufficient brightness can also be provided simultaneously.
