Technical field

The present invention relates to a kind of plasma panel (PDP), more specifically be, relate to having and prevent extraneous light reflection plasma panel with the structure that improves Display Contrast.

Background technology

PDP is generally a kind of display device, and the excited by vacuum ultraviolet fluorescent material that is produced by the gas discharge that takes place in discharge cell manifests predetermined picture therein.Because PDP (even screen sizes) may realize high-resolution, a plurality of people believe that PDP will become main plane of future generation display structure.

With reference to Figure 24, in traditional PD P, address electrode 101 is to form along the direction (directions X among the figure) on the metacoxal plate 100.Form dielectric layer 103 on the whole surface of metacoxal plate 100, wherein address electrode 101 is positioned on the metacoxal plate 100 so that dielectric layer 103 overlay address electrodes 101.Spaced walls 105 is formed on the dielectric layer by strip pattern and on corresponding to the position between the address electrode 101.Between spaced walls 105, form red, green and blue look fluorescence coating 107.

Prebasal plate 110 with metacoxal plate 100 facing surfaces on form the discharge that realizes by a pair of transparency electrode and bus electrode and keep electrode 112,113.Arrange discharge along the direction (Y direction) that is substantially perpendicular to the address electrode 101 of metacoxal plate 100 and keep electrode 112,113.On the whole surface of prebasal plate 110, form dielectric layer 116, form on prebasal plate 110 wherein electrode 112,113 is kept in discharge keeps electrode so that dielectric layer 116 coverings are discharged.Form MgO protective layer 118 and cover whole dielectric layer 116.

The zone that the address electrode 101 of metacoxal plate 100 and the discharge of prebasal plate 110 are kept between electrode 112,113 intersections becomes the zone that forms discharge cell.Be full of discharge gas in each discharge cell.

Keep in address electrode 101 and discharge and to apply address voltage Va between one of electrode 112,113 and come the calculated address discharge, thereby and be chosen in wherein the discharge cell that illumination takes place, keep to apply between the electrode 112,113 in a pair of discharge then and keep voltage Vs and keep discharge.Vacuum ultraviolet (VUV) the activating fluorescent layer that produce this moment sends visible light and realizes that image shows so that pass transparent prebasal plate 110.

Yun Hang PDP has and shows contrast ratio light-room contrast (brightroom contrast) and darkroom contrast (dark room contrast) to a certain extent in this way.The light-room contrast is meant when display screen is outside and has contrast when being subjected to influencing of this extraneous light more than or equal to the light source of 150lux and this PDP.Darkroom contrast is meant the contrast when display screen is outside when existing the light source that is less than or equal to 21lux and this PDP not to be subjected to influencing of this extraneous light substantially.

In traditional PD P, prebasal plate 110 is made by transparent glass material so that unavoidably produce the extraneous light reflection.When penetrating prebasal plate 110, arrive discharge cell, and when on fluorescence coating 107 or dielectric layer 116, being reflected, the reflection of extraneous light just takes place from the display screen light from outside.Extraneous light also can directly reflect on the outer surface of prebasal plate 110.

Externally light penetration prebasal plate 110 has just increased the brightness of black background with forming under the situation of reflection on fluorescence coating 107 or the dielectric layer 116.This has just reduced the darkroom contrast of screen.When extraneous light directly from the outer surface reflex time of prebasal plate 116, the part screen with regard to crested and can not see.This has just caused the light-room contrast's of screen decline.

Thereby, keep between the electrode 112,113 to form optical screen film in the discharge of traditional PD P, to hinder the light that enters by prebasal plate 110 and to prevent that it is reflected.This is the generic configuration among the PDP.United States Patent (USP) NO.5952782 and NO.6200182 disclose the PDP that uses this optical screen film between prebasal plate and fluorescence coating.

Yet, thereby along with optical screen film and contiguous region of discharge are set, in order to the material that hinders light discharging action is caused negative effect in the optical screen film on the inner surface of prebasal plate, make and can not normally discharge.In addition, optical screen film can not prevent from the reflection of the outer surface of prebasal plate.When PDP is placed the room that has used fluorescent lamp or other these type of high-intensity lighting systems, just may have problems (for example, significant reflection), thus can not prevent light-room contrast's reduction.

The color characteristics of red, green and blue look fluorescence coating has been determined the colour temperature of screen.Thereby the fluorescent material of these different colours layers of using in legacy system has different fluorescent material efficient and changes the brightness ratio.Thereby in order to improve colour temperature, the fluorescent material that has minimum brightness ratio in just must these the three kinds of colors to fluorescent material compensates.

In traditional PD P, be to carry out gamma (gray scale) compensation, to reduce the peak value of different colours in order to the usual way that carries out this color compensating.This is to not having the color of minimum brightness ratio, and for example red and green (for this example, supposing that blueness has minimum brightness ratio) carries out that the analog picture signal digitlization carries out before.The umber of pulse of keeping of the maximum brightness of therefore, expression redness and green just is brought down below blue quantity.In addition, the discharge cell that will comprise the fluorescence coating of the color that shows minimum brightness ratio is made maximum, and reduces to comprise the size of discharge cell capacity of the fluorescence coating of other two kinds of colors.This has further improved colour temperature.

Yet, in the above-mentioned method of utilizing grey level compensation, do not use the highest green and red brightness needed all 255 keep pulse.Thereby, for brightening gradually or the image of deepening, the green in the image and redly just show this variation not according to gradual manner by incremental mode.In addition, along with adopting the different size discharge cell, the possibility that misplaces electricity has just increased, and the required voltage range of stabilized driving has just been dwindled.

Comprise according to the plasma panel (PDP) of first embodiment and to be configured to by predetermined space substantially parallel first substrate 2 and second substrate 4.Non-discharge area 10 and

discharge cell

8R, 8G, 8B are defined by the spaced walls 6 between first substrate 2 and second substrate 4.

A plurality of address electrodes 12 are along second substrate 4, form with a direction (directions X among the figure) on first substrate, 2 facing surfaces.As example, address electrode 12 is to form by the strip pattern with 12 identical predetermined spaces of neighbor address electrode.The dielectric layer 14 of overlay address electrode 12 is formed on second substrate 4.

Spaced walls 6 defines a plurality of

discharge cell

8R, 8G, 8B and non-discharge area 10 in the slit of 4 of first substrate 2 and second substrates.In one embodiment, spaced walls 6 is formed on the dielectric layer 14, and this dielectric layer 14 is configured on second substrate 4 as mentioned above.

Discharge cell

8R, 8G, 8B represent such zone, to discharge gas wherein being provided and keeping voltage and can be expected at gas discharge wherein takes place by applying address voltage and discharge.Non-discharge area 10 is such zones, does not apply voltage therein so that be not desirably in gas discharge (for example, illumination) wherein takes place.Non-discharge area 10 is such zone, its size at least with the Y direction on being of uniform thickness of spaced walls 6.

With reference to Fig. 1 and 2, in by the center of passing each

discharge cell

8R, 8G, 8B and discharge cell abscissa H that arranges by directions X and Y direction respectively and ordinate V institute area surrounded, form the non-discharge area 10 that defines by spaced walls 6.In one embodiment, non-discharge area 10 is placed in the middle between adjacent abscissa H and adjacent ordinate V.In other words, in one embodiment every pair along directions X adjacent in twos discharge

cell

8R, 8G, 8B and another this type of is had common non-discharge area 10 along Y direction

adjacent discharge cell

8R, 8G, 8B.This structure that utilization is realized by spaced walls 6, each non-discharge area just has independently cellular construction.

Spaced walls 6 is defining

discharge cell

8R, 8G, 8B on address electrode 12 (directions X) direction with on the direction (Y direction) that is basically perpendicular to address electrode 12 formation

directions.Discharge cell

8R, 8G, 8B form in the mode that helps most gaseous diffusion.Particularly, when when increasing on the direction (directions X) of distance at configuration address electrode 12 at each

discharge cell

8R, 8G, 8B center, the width of each

discharge cell

8R, 8G, 8B end reduces along the Y direction.That is to say, as shown in Figure 1, according to when from the increase of the distance at

discharge cell

8R, 8G, 8B center end width W e being reduced to the mode of certain point, the width W c at

discharge cell

8R, 8G, 8B middle part is greater than the width W e of

discharge cell

8R, 8G, 8B end.Therefore, in first embodiment, up to reaching the precalculated position, spaced walls 6 is sealed

discharge cell

8R, 8G, 8B on this position by trapezoidal shaping for

discharge cell

8R, 8G, 8B.This causes each

discharge cell

8R, 8G, 8B to have octagonal integral planar shape.

Thereby the spaced walls 6 that defines non-discharge area 10 and

discharge cell

8R, 8G, 8B in a manner described comprises the first spaced walls parts 6a and

definite discharge cell

8R, 8G, 8B end that is parallel to address electrode 12 and the second spaced walls parts 6b that is not parallel to address electrode 12.In first embodiment, the second spaced walls parts 6b forms: extend to a bit by being predetermined angular with the first spaced walls parts 6a, extend on the Y direction then and pass address electrode 12.Therefore, by forming the second spaced walls parts 6b along being X-shaped between

discharge cell

8R, 8G adjacent on the direction of address electrode 12, the 8B basically.The second spaced walls parts 6b can also come the discharge cell of separating adjacent diagonally with non-discharge area therebetween.

Deposition red (R) in

discharge cell

8R, 8G, 8B, green (G) and blue (B) look fluorescent material are to form

fluorescence coating

16R, 16G, 16B respectively.

With reference to Fig. 3, when the degree of depth at discharge cell 8R two ends when discharge cell 8R centre distance the increases direction along address electrode 12 reduces.That is to say that along with when reducing from the distance at this center depth D e when directions X increases, the depth D e of discharge cell 8R end is less than the depth D c at discharge cell 8R middle part.Form the discharge cell 8G of other colors by the mode identical with

discharge cell

8R, 8B, thus move by identical mode.

For first substrate 2, first substrate 2, with second substrate, 4 facing surfaces on form a plurality of discharges and keep electrode 22.Discharge is kept electrode 22 and is included in last scan electrode 18 and the show electrode 20 that extends of the direction (Y direction) that is basically perpendicular to address electrode 12 directions (directions X).In addition, formation dielectric layer 24 covers discharge and keeps electrode 22 on the whole surface of first substrate 2, and forms MgO protective layer 26 on dielectric layer 24.

Scan electrode 18 and show electrode 20 comprise the bus electrode 18a, the 20a that form by strip pattern respectively and extend out and the projection electrode 18b, the 20b that form from

bus electrode

18a, 20a respectively.For every

capable discharge cell

8R, 8G, 8B along the Y direction, bus electrode 18a stretches into the end of

discharge cell

8R, 8G, 8B, and bus electrode 20a stretches into the other end of

discharge cell

8R, 8G, 8B.Therefore, each

discharge cell

8R, 8G, 8B have a bus electrode 18a and a bus electrode 20a who places on the other end who places on the end.

That is to say, for every

capable discharge cell

8R, 8G, 8B along the Y direction, projection electrode 18b and corresponding bus electrode 18a overlaid and stretch into the zone of

discharge cell

8R, 8G, 8B from this bus electrode 18a.Projection electrode 20b and corresponding bus electrode 18b overlaid and stretch into the zone of

discharge cell

8R, 8G, 8B from this bus electrode 18b.Thereby, in corresponding to each zone of each

discharge cell

8R, 8G, 8B, form a projection electrode 18b and a projection electrode 20b in twos relatively.

Projection electrode 18b, the near-end of 20b (for example,

projection electrode

18b, 20b link to each other with

bus electrode

18a, 20a and from its extended spot) form corresponding to the shape of

discharge cell

8R, 8G, 8B end.That is to say, when from the distance at

discharge cell

8R, 8G, 8B center when directions X increases, corresponding thereby the width of

projection electrode

18b, 20b near-end reduces along the Y direction with the shape of

discharge cell

8R, 8G, 8B end.

By having the transparency electrode of good light transmissivity, for example ITO (tin indium) electrode is realized projection electrode 18b, 20b.In one embodiment, such as silver (Ag), the metal material of aluminium (Al) and copper (Cu) is made

bus electrode

18a, 20a.

On

second substrate

4 and 6 zones of spaced walls, the extraneous light absorption piece is set corresponding to non-discharge area.The extraneous light absorption piece is configured to the contiguous dielectric layer 14 that is formed at second substrate 4.In first embodiment, extraneous light absorption piece 28 is formed on the dielectric layer 14 zone corresponding to non-discharge area 10 to minimize the reflecting brightness of PDP.

Fig. 4 is the cutaway view along Fig. 1 cathetus B-B.Extraneous light absorption piece 28 is made by black layer or dark shade (dark shade) layer that approaches black.As mentioned above, extraneous light absorption piece 28 is placed on the dielectric layer 14 between second substrate 4 and spaced walls 6.If desired, as shown in Figure 5, extraneous light absorption piece 28 can be configured in the groove 14a that is formed in the dielectric layer 14.If used structure as shown in Figure 5, just eliminated the difference in height between dielectric layer 14 and the extraneous light absorption piece 28, thereby whole dielectric layer 14 and extraneous light absorption piece 28 are exactly flat.

Edge along first substrate 2 and second substrate 4 provides frit, and under the state of filling discharge gas (being generally the Ne-Xe mist) between first substrate 2 and second substrate 4 with its sealing.

If in the partial discharge unit, for example apply address voltage Va between the address electrode 12 of discharge cell 8R and the scan electrode 18, the address discharge just takes place in discharge cell 8R.Thereby, on the dielectric layer 24 of keeping electrode 22 is discharged in covering, accumulate interface charge, thereby select specific discharge cell 8R.

Subsequently, if between the scan electrode 18 of selected discharge cell 8R and show electrode 20, apply and keep voltage Vs, just excite plasma discharge in the slit between scan electrode 18 and show electrode 20, and send VUV light by being activated at the Xenon that produces in the plasma discharge process.The fluorescence coating 16R of this VUV light excitation discharge cell 8R, thus predetermined picture shown.

, disappear then to be roughly arc by the plasma discharge of keeping voltage Vs generation to the scattering of the perimeter of discharge cell 8R.In first embodiment, it is corresponding with this type of scattering phase of plasma discharge to form each

discharge cell

8R, 8G, 8B.Thereby, effective continuous discharge takes place on the whole zone of

discharge cell

8R, 8G, 8B, thereby increases discharging efficiency.

In addition, when near the perimeter of

discharge cell

8R, 8G, 8B, just increased, thereby increased illumination efficiency with fluorescence coating 16R, the 16G of corresponding region of discharge, the area of 16B contact.Equally, non-discharge area 10 absorbs the heat that sends from

discharge cell

8R, 8G, 8B and this heat is discharged outside the PDP, thereby improves the heat dissipation characteristics of PDP.

Along with extraneous light absorption piece 28 is installed in first embodiment, the extraneous light that enters PDP by first substrate 2 just has been absorbed, thereby has reduced the reflecting brightness of this PDP.Finally, improved the light-room contrast of screen.

Describe with reference to Fig. 6-10 pair of manufacturing below according to the PDP of first embodiment.

At first, will be printed on second substrate according to strip pattern such as the conductive paste of silver (Ag) cream with reference to Fig. 6.Drying is also fired this conductive paste and is come calculated address electrode 12.Stamp insulating material then on whole surface second substrate 4, that formed address electrode 12, subsequent drying is also fired this insulating material to form dielectric layer 14.

Subsequently,, on dielectric layer 14, will form the area deposition blacking of non-discharge area, to form extraneous light absorption piece 28 with reference to Fig. 7.As example, comprise MnO by at first producing ₂, traditional paint vehicle, organic bond and frit blacking, on dielectric layer 14, print then, dry and fire this blacking and form extraneous light absorption piece 28.

In another embodiment,, in dielectric layer 14, form groove 14a, then blacking is deposited among the groove 14a, to form the extraneous light absorption piece corresponding to the zone that will form non-discharge area with reference to Fig. 8.

Subsequently, with reference to Fig. 9, on dielectric layer 14, form spaced walls 6, to define non-discharge area 10 and

discharge cell

8R, 8G, 8B.Can on dielectric layer 14, spaced walls 6 be printed to required pattern, then it be carried out drying and fire.Perhaps, the spaced walls material can be deposited on the whole dielectric layer 14, sandblasting subsequently to handle removes institute's favored area, thereby and forms the spaced walls 6 that defines (becoming required pattern) non-discharge area 10 and
