One of two scanning electrodes or a sustaining electrode is arranged in a dividing wall or is arranged on the side wall of the dividing wall through changing a configuration structure of traditional three electrodes, and the two scanning electrodes share the sustaining electrode arranged on the dividing wall so as to reach the purpose of manufacturing the alternating-current plasma display panel with high definition and high precision.
Description
Technical field
The present invention relates to a kind of ac plasma display panel, particularly relate to the ac plasma display panel that two scan electrodes shared are kept electrode.
Background technology
Fig. 1 is the sectional view that shows conventional AC plasma display structure.This ac plasma display panel (AC Plasma Display Panel; Be designated hereinafter simply as AC PDP), can be divided into superstructure and substructure.With regard to superstructure, on the surface of front glass substrate 1, form a pair of upper electrode 4, respectively as scan electrode (Y) with keep electrode (X), on upper electrode 4, adopt such as methods such as print process formation conductive layer 2.In addition, on conductive layer 2, be formed with protective seam 3.With regard to substructure, on the glass substrate 11 of back, form lower electrode 12, as address (address) electrode.Constitute a discharge space between above-mentioned front glass substrate 1 and the back glass substrate 11, in above-mentioned discharge space, be formed with dividing wall 6, to avoid the cross-talk (cross talk) between the adjacent plasma display unit and to interfere with each other.In addition, be coated with phosphor body 8 on dividing wall 6 and the lower electrode 12, then be filled with discharge gas in the above-mentioned discharge space, for example helium (He), neon (Ne).
During above-mentioned AC PDP is keeping (sustaining period), when applying driving voltage to top electrode 4, having plasma discharge region 5 between upper electrode 4 forms, wherein plasma discharge region (is roughly parallel to front glass substrate 1, and) near plane, and meeting generating plane discharge generation ultraviolet ray 7, and then excite phosphor body 8 to make it luminous.
Among traditional AC PDP, each upper electrode 4 (being X or Y electrode) is made of transparency electrode (for example ITO) and bus electrode (for example Cr/Al/Cr or Cr/Cu/Cr).Because bus electrode is not a transparent material, therefore can influence the aperture opening ratio of AC PDP.
Among traditional AC PDP, because plasma discharge region 5 is roughly parallel to front glass substrate 1, therefore in the ultraviolet ray 7 that interdischarge interval sent, can't be dispersed in effectively in the discharge space between above-mentioned front and back glass substrate (1,11), so can influence the visible light luminescence efficiency of phosphor body.
Among traditional AC PDP, upper electrode 4 (being X and Y electrode) generally all is arranged on the front glass substrate 1, if adjust the words in the gap (Gap) of X and Y electrode according to request for utilization, then certainly will also to adjust the spacing (Pitch) between the dividing wall 6, so be unfavorable for the adjustment of X and Y electrode separation.In addition, when strengthening X and Y electrode gap (Gap), also strengthened the spacing (Pitch) of dividing wall 6, with regard to display unit (Display Unit) for regard to the AC PDP of fixed measure, because the pixel cell on the address electrode direction reduces, therefore can reduce the whole resolution of AC PDP, quite unfavorable for the making of the AC PDP of high-resolution, high precision.
