Wherein, intermediate glass substrate 106 comprises: be formed on the intermediate glass real estate and show the lip-deep public addressing electrode 162 of glass substrate, the opaque medium layer that covers public addressing electrode, barrier, and phosphor powder layer to first; And be formed on intermediate glass substrate 106 towards second show glass substrate 104 lip-deep barrier and phosphor powder layer.
Wherein, First shows that glass substrate 102 comprises that being arranged on first shows first show electrode 122 on the glass substrate 102,122 ', first transparent dielectric layer 124, and first protective seam 126; Second shows that glass substrate 104 comprises that being arranged on second shows second show electrode 142 on the glass substrate, 142 ', second transparent dielectric layer 144, and second protective seam 146; Wherein, Between the intermediate glass substrate 106 and first protective seam 126, form first discharge space, between the intermediate glass substrate 106 and second protective seam 146, form second discharge space.
Wherein, the thickness of intermediate glass substrate is 100 microns to 300 microns.First shows that glass substrate and second shows that the structure of glass substrate can be identical.
Structure according to the plasma display system of the embodiment of the invention is three parallel glass substrates, wherein first show on the glass substrate with the second demonstration glass baseplate surface on structure identical, be manufactured with show electrode, the addressing electrode on the shared Intermediate substrate.Show on the glass substrate with second first then to show that symmetrical show electrode on the glass substrate links to each other and addressing electrode is connected to same set of driving circuit together, realize the synchronous demonstration of front and back display screen.The present invention with existing double-sided plasma display in comparison, has simplified technological process owing to adopt public addressing electrode, has shortened operation, and yields is high, and cost of manufacture is low.
For achieving the above object, in an embodiment of the present invention, can realize through following technical scheme.Double-sided plasma display device of the present invention is selected three glass substrates for use, and wherein first shows that glass substrate and second shows that the structure on the glass substrate apparent surface is identical: make transparent display electrode, transparent dielectric layer, protective seam; Middle glass substrate is extremely thin, has only about the 100-300 micron, and the surface makes public addressing electrode above that; The opaque medium layer, barrier, fluorescent powder; Constitute discharge space with the first demonstration glass substrate, only make barrier, fluorescent powder at its lower surface; And the glassy layer of substrate own can serve as dielectric layer, and barrier in the above and phosphor powder layer and second show that glass substrate constitutes discharge space.Show that with first the show electrode and second of glass substrate shows that the show electrode correspondence of glass substrate couples together then; Addressing electrode on shared Intermediate substrate is connected on the drive unit; Drive first simultaneously and show that the display screen that glass substrate, second shows that glass substrate and intermediate glass substrate are formed carries out the image display driver, circuit arrangement is made up of XY driving, power supply, interface, support and aluminium sheet etc.Like this, receive the picture signal of coming and to drive the display screen that the first demonstration glass substrate, second shows glass substrate and intermediate glass substrate composition respectively simultaneously through driving circuit, to reach the purpose of plasma panel double-sided display.
Double-sided display plasma panel according to an embodiment of the invention; Its first demonstration glass substrate and second shows that the making of glass substrate is the same with traditional plasma panel making; Existing technology capable of using; Different is the making of the substrate in middle layer, and first shows that glass substrate and second shows two shared addressing electrodes of discharge space of glass substrate.And, adopt a cover drive circuit system, simple in structure, easy to make, process route is short, can realize cost degradation.The double-sided plasma display device that is made into can be applied to the place that airport lounge, railway station Waiting Lounge, megastore, stock market etc. show public information, saves the space.
Still with reference to figure 1 and Fig. 2 embodiments of the invention are described.Fig. 1 and Fig. 2 are respectively part three-dimensional structure diagram and the outboard profiles according to the double-sided display plasma display of the embodiment of the invention.Structure comprises that first shows that glass substrate 102, the second shows glass substrate 104 and Intermediate substrate 106.First shows that glass substrate 102 and second shows that the structure of glass substrate 104 is identical, comprises show electrode 122,122 ' and 142,142 ' respectively, transparent dielectric layer 124,144, protective seam 126,146; The structure of Intermediate substrate 106 is: with the first demonstration glass substrate, 102 facing surfaces opaque medium layer 164 is arranged, addressing electrode 162, and thin glass layer 166, the thickness of glass have only about the 200-300 micron; In addition, phosphor powder layer 130,150 is all arranged on the two sides of Intermediate substrate 106, and barrier 128,148.Constitute discharge space 168 between protective seam 126 and the opaque medium 164; Constitute discharge space 170 between protective seam 146 and the thin glass layer 166; Here, thin glass layer 166 has played the effect of dielectric layer, because the opacity of dielectric layer 164; Can eliminate influencing each other of tow sides phosphor powder layer 130,150.Two discharge space 168,170 shared addressing electrodes 162.Then, the show electrode 122 of correspondence is connected with 142,122 ' is connected with 142 ', constitutes a pair of XY electrode, and other counter electrode connected mode is also like this.The show electrode that connects is connected to drive unit with shared addressing electrode; Like this; Can show that to first the display screen that glass substrate, second shows that glass substrate and intermediate glass substrate are formed drives, and shows identical image simultaneously once the cover driving circuit.Simultaneously owing to adopted same set of driving circuit device, two-sided picture shows signal is stable, practices thrift circuit one cover than two single face plasma displays, and public addressing electrode has shortened process route, and corresponding cost just can reduce.Still all has remarkable advantages technically in production.Plasma display system according to the embodiment of the invention is widely used, and the double-sided display propagation amount of resting doubles, and audient's number also can double, and is particularly suitable for being placed in the public place as large-scale display device, also can be used as home-use partition decoration etc.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
