(manufacture method of plasma display)
Then, use Fig. 2 and Fig. 5 that the manufacture method of the plasma display in the present embodiment is described.Fig. 5 is the flow chart of the manufacture method of the plasma display in the present embodiment.
At first, as shown in Figure 2, the inner surface of substrate 2 forms show electrode 12 and dielectric layer 13 (step 32) in front.In addition, the inner surface of substrate 1 forms addressing electrode 11 and dielectric layer 19 (step 42) overleaf.
Then, form spaced walls 15 and ultraviolet screener wall 24 (step 44) simultaneously on the surface of the dielectric layer 19 of substrate 1 overleaf.The inner surface that its concrete method is a substrate 1 at first overleaf forms the tunicle of ultraviolet absorption material.Specifically, the pasty state ultraviolet absorption material is coated with into 200 μ m left and right thicknesses, dryly forms above-mentioned tunicle by print process etc.Then, laminating film resist (DFR) on the surface of above-mentioned tunicle.Then, with this DFR exposure and development, with the shape formation pattern of spaced walls 15 and ultraviolet screener wall 24.Then, implement sand-blast as mask, with the shape formation pattern of above-mentioned tunicle with spaced walls 15 and ultraviolet screener wall 24 with this DFR pattern.Then, peel off and remove DFR, back substrate 1 is put in the sintering furnace, spaced walls 15 and ultraviolet screener wall 24 are carried out sintering.Thus, form spaced walls 15 and ultraviolet screener wall 24 on the inner surface of substrate 1 overleaf.
In addition, as other method that forms simultaneously, can be before forming addressing electrode 11 and dielectric layer 19, lamination DFR on the inner surface of substrate 1 overleaf.Then with this DFR exposure and development, with the shape formation pattern of spaced walls 15 and ultraviolet screener wall 24.Then, implement sand-blast with this DFR pattern as mask, the back substrate 1 that will contain ultraviolet absorption materials such as glass digs to the 150 μ m left and right sides degree of depth.Then, peel off and remove DFR.Thus, be directly formed to spaced walls 15 and ultraviolet screener wall 24 on the inner surface of substrate 1 overleaf.After this, forming addressing electrode 11 grades gets final product.And, also can form spaced walls 15 and ultraviolet screener wall 24 simultaneously by the method beyond above-mentioned.
Then, at the inboard of the spaced walls of adjacency coating fluorophor 17.
Then, the configuration of the entire circumference of substrate 1 seals material 20 and getter 22 (step 46) overleaf.The configuration of sealing material 20 is undertaken by the encapsulant of coating pasty state.The coating of encapsulant can utilize drops such as distribution (dispenser) method or ink-jet method spue method or print process etc.In addition, the configuration of getter 22 is undertaken by the SrO material piece of pasting about width 3～10mm, about thickness 150 μ m.This SrO material piece can followingly form: join the SrO powder in the mould and at 200～400kgf/cm
2Forming under the pressure, further at N
2In about 30 minutes of about 1200 ℃ of following sintering, form above-mentioned SrO material piece in the atmosphere.
Then, front substrate 2 and back substrate 1 are put in the vacuum apparatus for continous treatment 50, two substrates 1,2 is not exposed to and proceeds to following sealing process under the atmosphere.
At first, in a vacuum back substrate 1 is heated, carry out from the degassing processing and the pump-down process (step 48) of the sealing material 20 that contains resin material.By this heating, can be in the activation processing of carrying out when the degassing of sealing material 20 is handled, carrying out getter 22.In addition, in a vacuum front substrate 2 is heated, carry out handling (step 34) from the degassing of dielectric layer 13 grades.Then, form diaphragm 14 (step 36) by EB vapour deposition process etc. on the inner surface of substrate 2 in front.
And, in order to reduce the power consumption of PDP, the MgO that adopts SrO class materials such as (SrCa) O to substitute is in the past studied as the constituent material of diaphragm 14 recently.This SrO class material is compared with MgO, and moisture absorption is high and have because moisture absorption and the character of variable color.For this problem; by in vacuum apparatus for continous treatment 50 from the degassing treatment process of two substrates 1,2 through the formation operation of over-protective film 14 sealing process until two substrates 1,2, can prevent diaphragm 14 because the variable color that moisture absorption causes and the rising of discharge voltage.
Then, sealing two substrates 1,2 (step 52).Specifically, at first in chamber (chamber), drop into two substrates 1,2, in this chamber, import discharge gas.Then, aim at (contraposition) two substrates 1,2 and carry out temporary fixed.Then, two substrates 1,2 is applied the voltage discharge of wearing out.Further, the electrode of two substrates 1,2 is applied driving voltage and carry out luminescent inspection.Its result removes the back substrate 1 or the front substrate 2 that note abnormalities, fixes between the normal luminous two substrates 1,2 confirming.Specifically, when constituting sealing material 20 by uv curing resin,, when constituting sealing material 20 by heat-curing resin, sealing material 20 is solidified by sealing material 20 is heated by to sealing material 20 irradiation ultraviolet radiations.Thus, under the state in the inside that discharge gas is sealing into two substrates 1,2, sealing two substrates 1,2.
(fuchsin(e)test, ageing test)
The present inventor carries out the fluctuation that discharge voltage is measured in fuchsin(e)test for PDP in the above-mentioned present embodiment and PDP of the prior art.PDP in the present embodiment comprises getter 22 and ultraviolet screener wall 24 as shown in Figure 2.Specifically, as getter 22, adopt at N
2The sheet getter that sintering SrO obtains in the gas.In addition, as the constituent material of ultraviolet screener wall 24, adopt the PbOB identical with spaced walls 15
2O
3SiO
2, form ultraviolet screener wall 24 simultaneously with spaced walls 15.And sealing material 20 adopts uv curing resin.In addition, as diaphragm 14, form the thickness 8000 that contains SrO20mol%CaO by the EB vapour deposition process
Tunicle.In addition, as discharge gas, enclose Ne4%Xe gas with 400Torr.
Therewith relatively, PDP of the prior art is for removing the PDP of getter 22 and ultraviolet screener wall 24 among the PDP from present embodiment.
Fuchsin(e)test is studied the standing time and the relation of discharge sustaining voltage by carrying out placing PDP under 85 ℃ in the thermostat of humidity 95%.
Fig. 6 A and Fig. 6 B are the fuchsin(e)test result curve figure of PDP, and Fig. 6 A is the situation of the PDP in the present embodiment, and Fig. 6 B is the situation of PDP of the prior art.And in the following curve chart, in the PDP that contains 300 two-dimensional matrix discharge cells (cell), making whole discharge cells necessary driving voltage that begins to discharge is final discharge cell point modulating voltage.In addition, when the state that whole discharge cells are lit a lamp slowly reduced driving voltage, the voltage that initial discharge cell is turned off the light was the first discharge cell light-off voltage.
Under the situation of PDP of the prior art shown in Fig. 6 B, the first discharge cell light-off voltage and final discharge cell point modulating voltage significantly increase under the placement of short time.Think that this is because the moisture in the thermostat sees through the inside that the sealing material invades PDP, has reduced the purity of discharge gas.
Therewith relatively, under the situation of the PDP in the present embodiment shown in Fig. 6 A, even obtained increasing standing time voltage fluctuation also in 5V, can problematic result in practicality.Think that this is that the purity that has suppressed discharge gas reduces owing to the moisture that invades the inside of PDP through the sealing material is adsorbed by getter.
In addition, the present inventor carries out ageing test for the PDP in the present embodiment and PDP of the prior art the fluctuation of discharge voltage is measured.As the PDP in the present embodiment,, adopt the PDP that removes getter in order to confirm the effect of ultraviolet screener wall.In addition, as PDP of the prior art, adopt the PDP that removes ultraviolet screener wall and getter.
Ageing test is undertaken by at room temperature in the atmosphere of humidity 50% PDP being applied long-time voltage, and the ageing time and the relation of discharge sustaining voltage are investigated.
Fig. 7 A and Fig. 7 B are the ageing test result curve figure of PDP, and Fig. 7 A is the situation of the PDP in the present embodiment, and Fig. 7 B is the situation of PDP of the prior art.
Under the situation of PDP of the prior art shown in Fig. 7 B, the discharge sustaining voltage raise when ageing time increased, and final discharge cell point modulating voltage increases 30V approximately after 2000 hours the burin-in process.Think that this is because the sealing material is incided in the ultraviolet ray of the discharge generation by PDP for a long time, the resin material that the sealing material contains is decomposed, the foreign gas of CH class is released to PDP inside, has reduced the purity of discharge gas.
Therewith relatively, under the situation of the PDP in the present embodiment shown in Fig. 7 A, even after carrying out 2000 hours aging, voltage raises also below 10V.Think that this is because the ultraviolet ray of the discharge generation by PDP is absorbed by the ultraviolet screener wall, prevent that thus foreign gas from discharging from the sealing material, thereby the purity that has suppressed discharge gas reduces.
As mentioned above, the PDP in the present embodiment has the structure that forms getter along interior all continuously or intermittentlies of sealing material.According to this structure, owing to can suppressing to be sealing into the purity reduction of the discharge gas between a pair of substrate by getter absorption by the foreign gas that seals material release and through sealing the foreign gas that material is invaded.Therefore, can suppress the rising of discharge voltage.
In addition, owing to can adsorb foreign gas, can prevent that foreign gas is had hygroscopic diaphragm absorption by getter.Thus, the reduction of the secondary electron yield of substrate surface can be suppressed, the rising of discharge voltage can be suppressed.Further, can not be trapped between substrate from the foreign gas of diaphragm disengaging, can be adsorbed by getter at the voltage that applies the stipulated time between substrate (initial burin-in process).Thus, the disengaging of foreign gas can be promptly finished, initial ageing treatment time can be shortened.
In addition, the PDP in the present embodiment has the structure that forms the ultraviolet screener wall along the interior week of above-mentioned sealing material continuously.According to this structure,, can prevent to incide the sealing material because the ultraviolet ray that produces in the inside of sealing panel is absorbed by the ultraviolet screener wall.Thus, can suppress foreign gas and discharge, can suppress the rising of discharge voltage from the sealing material.
And technical scope of the present invention is not limited by the respective embodiments described above, comprises the mode of the respective embodiments described above being carried out various changes without departing from the spirit and scope of the present invention yet.
That is, concrete material of enumerating in each execution mode or structure etc. only are an example, can carry out appropriate change.
