- FIG. 1 is an exploded perspective view showing a panel structure according to an embodiment of the present invention.
- the panel 1 has a front substrate 2 and a rear substrate 3 arranged to face each other.
- the front substrate 2 has a plurality of pairs of scan electrodes 5 and sustain electrodes 6 which are paired as display electrodes on the front glass plate 4 in parallel with each other.
- a dielectric layer 7 is formed so as to cover scan electrode 5 and sustain electrode 6, and a protective layer 8 is formed on dielectric layer 7 so as to cover the surface. Discharge traces described later are formed on the surface of the protective layer 8 by aging.
- On the back substrate 3, a plurality of data electrodes 10 are formed on a back glass plate 9 in parallel with each other, and a dielectric layer 11 is formed so as to cover the data electrodes 10.
- a plurality of partitions 12 are formed on the dielectric layer 11 in parallel with the data electrodes 10, and the phosphor layers 13 are formed on the surface of the dielectric layer 11 and the side surfaces of the partitions 12. . Further, a discharge gas is sealed in a discharge space 14 sandwiched between the front substrate 2 and the rear substrate 3.
- FIG. 2 is an electrode array diagram of panel 1 according to the embodiment of the present invention.
- Data electrodes 10 to 10 m in m columns are arranged in the column direction, and n rows of scanning electrodes are arranged in the row direction.
- (Scan electrode 5 in FIG. 1) and sustain electrode 6 i S n in n rows are alternately arranged.
- the gap formed by the scan electrode 5 and the sustain electrode 6 for each discharge cell 18 is called a discharge gap 20, and the gap between the discharge cells, that is, the scan electrode 5;
- the gap created by electrode 6 is called adjacent gap 21.
- FIG. 3A is a diagram schematically showing discharge marks (spatter marks during aging) observed on the surface of the protective layer after the panel was split after aging treatment of the panel according to the embodiment of the present invention. Shows a spaghetti mark.
- the discharge trace on the scan electrode 5 side spreads over almost the entire width of the electrode, whereas the discharge trace on the sustain electrode 6 side is a region close to the scan electrode 5 forming a pair as a display electrode, that is, a discharge gap 20. It is characterized by being localized in the side region. That is, the discharge trace on the sustain electrode 6 side is formed narrower than the discharge trace on the scan electrode 5 side.
- the surface of the protective layer 8 is sputtered by aging, but the amount is very small. Therefore, it is generally difficult to observe a discharge trace generated by aging with a normal optical microscope.
- a scanning electron microscope (SEM) that responds sensitively to the surface shape of the material is suitable for observing these discharge marks. The SEM scans the sample surface with the electron beam and observes the secondary electron image emitted from the sample surface.
- the surface of the MgO film that forms the protective layer has irregularities of several tens nm to 100 nm immediately after film formation, and when the surface of the protective layer is sputtered by aging, these minute irregularities become smoother. .
- the reasons for forming asymmetric discharge traces on the scan electrode 5 side and the sustain electrode 6 side are as follows.
- FIG. 3B is a diagram schematically showing discharge traces necessary for reducing and stabilizing a discharge starting voltage in a sustain discharge.
- a rectangular voltage pulse is applied between the scan electrode 5 and the sustain electrode 6 to generate a discharge. Therefore, a discharge occurs between the two electrodes near the discharge gap 20. Therefore, it is necessary that this part is sufficiently aged, that is, the surface of the protective layer in this part is sufficiently sputtered.
- the surface of the protective layer is sprinkled as in the case of aging, and the shape change of the protective layer surface due to the spatter appears as a change in the sustain discharge voltage, and the display characteristics Because it has a bad influence on In order to prevent such a state, aging of the discharge gap 20 side of both the scanning electrode 5 and the sustaining electrode 6 is prioritized, and the discharge is performed so that there is almost no change in the shape of the protective layer surface during the sustaining discharge during panel operation. It is necessary to make the discharge trace on the gap 20 side somewhat deeper than the discharge trace on the adjacent gap 21 side. Conversely, it can be said that a stable sustain discharge can be obtained without performing strong aging such that a deep discharge mark is formed in the region on the adjacent gap 21 side.
- FIG. 3C is a diagram schematically showing a discharge trace necessary for reducing and stabilizing a discharge starting voltage in a write discharge.
- Write discharge occurs between the scan electrode 5 and the data electrode 10. Therefore, in order to stabilize the driving voltage during writing without fluctuation during the panel operation, the entire surface of the scan electrode 5 side facing the data electrode 10 is aged, and the entire surface of the scan electrode 5 side is uniformly sputtered. It is desirable to have a discharge trace after sunset. In other words, aging (in other words, formation of discharge marks) on the sustain electrode 6 side is not so important as far as writing discharge is concerned.
- FIG. 3D is a diagram schematically illustrating an example of the distribution of the depth of the discharge trace of the panel according to the embodiment of the present invention.
- the depth of the discharge trace due to aging discharge does not take a binary distribution as shown in Fig. 3A, but is distributed continuously as shown in Fig. 3D.
- the discharge traces in the region far from the paired scan electrode 5 as the display electrode are formed shallower than the discharge traces in the region near the paired scan electrode 5 as the display electrode. Have been.
- the spatter of the protective layer 8 can be minimized, so that the life of the panel can be extended, and in addition, the time required for the aging can be shortened, and the power consumption can be reduced. It can also increase efficiency.
- FIGS. 4A and 4B are diagrams showing an example of a paging waveform for forming an asymmetric discharge trace in the embodiment of the present invention, which includes an alternating voltage component between scan electrode 5 and sustain electrode 6.
- Apply voltage As shown in FIG. 4A, the voltage waveform applied to the scan electrode 5 has a sharp fall and a gentle slope.
- the voltage waveform applied to the sustain electrode 6 has a steep rise and a gentle slope as shown in FIG. 4B. Note that both the rising of the voltage waveform applied to the scanning electrode 5 and the falling of the voltage waveform applied to the sustain electrode 6 have a gentle slope, but either one has a gentle slope. You can.
- the voltage waveform applied to the data electrode 10 is not shown, but may be left open or set to the ground potential.
- FIG. 4C is a diagram schematically showing a waveform of light emitted from the panel detected by the photosensor according to the embodiment of the present invention.
- a strong discharge occurs at a sharp voltage change timing and a weak discharge occurs at a gentle voltage change timing.
- the scanning electrode 5 side becomes a cathode, so that positive ions fly and spatter strongly on the surface of the protective layer 8.
- electrons fly on the sustaining electrode 6 side, but the electrons are light. Therefore, the protective layer 8 on the sustain electrode 6 side is not strongly spattered.
- the subsequent weak discharge is a discharge localized around the discharge gap 20.
- the AC-type three-electrode PDP requires aging for two major discharge modes, sustain discharge and write discharge, but is shown in Fig. 3A by performing minimum aging. Such ideal discharge marks are formed on the protective layer 8. Conversely, by designing an aging waveform and an aging device so as to form discharge marks as shown in FIG. 3A, a panel with a long life can be provided. As described above, since the plasma display panel of the present invention has a small discharge mark during aging, it can provide a plasma display panel with a long life. Industrial applicability
- the panel and its aging method of the present invention can provide a panel with a long life because discharge traces are formed small during aging, and are useful as an AC type plasma display panel and its aging method. is there
