Abstract

A method is provided to steadily produce a gas discharge panel, such as a PDP, in which a panel and the top of the barrier ribs are in intimate contact in entirety. First a surrounding unit for the gas discharge panel is formed, then a process for sealing the surrounding unit with a sealing material inserted between two panels at the rim is performed while pressure is adjusted so that pressure inside the surrounding unit is lower than pressure outside. With this construction, the panels constituting the surrounding unit are bonded together while they are pressurized from outside. As a result, a panel and the top of the barrier ribs on the other panel are bonded together while they are in intimate contact in entirety. To fully acquire these effects, it is preferable that the adjustment of pressure starts before the sealing material hardens. During, before, or after the sealing step, an energy such as laser beams or ultrasonic waves may be radiated onto the top of the barrier ribs to bond a panel and the top of the barrier ribs in entirety almost without a gap between them.

Description

Make the encapsulating method and the equipment of high-performance gas discharge panel
The present invention relates to a kind of method of making gas discharge panel, the method for especially bond front panel and rear board.
In recent years, along with to for example growth day by day of high definition TV demand of high-quality large screen television, the display that is suitable for this TV, for example cathode ray tube (CRT), LCD (LCD) and plasm display panel (PDP) constantly development.
CRT has been widely used as television indicator, and its resolution and image quality are very excellent.But along with the increase of screen size, its thickness and weight also increase thereupon.Therefore CRT is not suitable for the large-screen more than 40 inches.The LCD power consumption is little, and can operate under low-voltage.But, makes big lcd screen and exist difficulty technically, and the field-of-view angle of LCD is restricted.
On the other hand, can make the little PDP of the big thickness of screen, 50 inches PDP product is developed out.
PDP has two kinds: once-through type (DC) and AC type (AC).At present, PDP mainly is an AC type, because they are suitable for large-screen.
AC surface discharge type PDP is a kind of typical interchange PDP, generally form by front panel, rear board, they be connected with electrode respectively and make two panels electrode toward each other.Space between front panel and the rear board is blocked rib and is divided into a plurality of spaces.Each of a plurality of spaces between these barrier ribs is all filled by in discharge gas and the red, green, blue fluorescent material any.When causing to each electrode application voltage, drive current when discharge sends ultraviolet light.This ultraviolet excitation fluorescent material.Be subjected to the excited fluorescent material and send red, green, blue.The light of these colors of being sent forms image on screen.
This PDP generally makes according to following technology.On the surface of plate barrier rib is set in the back; Form phosphor layer in the groove between barrier rib; Front panel is lain against on the top of barrier rib, form peripheral cell (front panel and rear board are bonded together, and the inner space is wherein arranged), the edge of peripheral cell, promptly front panel and rear board are sealed with encapsulant; The gas of discharging the inner space forms vacuum; This inner space is full of discharge gas.
Encapsulant generally is thermoplastic low-melting glass.Panel is being put together with before forming peripheral cell, the mixture of low-melting glass and adhesive is being applied to the edge of front panel or rear board by distributor etc.In seal process, by panel being heated to the temperature more than the low-melting glass softening point, make the encapsulant that edges cover applied of peripheral cell simultaneously, panel just is bonded together, with fixing outermost zones such as clips.
But, adopt the PDP of this method manufacturing between its barrier rib and rear board, the slit to be arranged.The slit of the difference on different barrier ribs or each barrier rib is all different.Reason is as follows.(1) in the barrier rib material being placed on the process of making barrier rib on the rear board, the height change of the barrier rib of generation.(2) heating process of carrying out before sealing, in the process that for example curing of barrier rib, fluorescent material, electrode and insulating barrier, and seal glass layer cures temporarily, panel and barrier rib are impaired.
In addition, in the seal process of PDP, the fastened instrument in the edge of front panel and rear board for example clip is fixed, and is subjected to displacement after the location that faces with each other to prevent panel.The leverage but edge this fastening is easy to and between the top, barrier layer of center and front panel, produce the slit.And, because the pressure that fastened tools produced is different, form uneven slit usually.
In the PDP that makes by the seal process that produces this slit, when PDP is activated, produce usually and crosstalk, perhaps between barrier rib and panel, produce noise because of the panel vibration that discharge etc. cause.
The practical new case 1-113948 of Japan discloses a kind of technology, wherein in front plate and rear board be placed with face with each other and bonding before, apply low-melting glass at the top on barrier layer.When the entire top that adopts this technology with front panel and barrier rib is bonded together, even in the inner space during by high pressure filling discharge gas peripheral cell can not expand yet.And the sealed material in the slit between barrier rib and the front panel is filled.Therefore, this technology has solved the problem of vibration.
But, in practice, be difficult to the entire top and the front panel of barrier rib are bonded together.Usually a part of top that also remains barrier rib is not connected.Therefore, this technical deficiency is to solve the problem of pressure.Especially, the barrier rib height on plate in the back leaves mass part and is not connected not simultaneously.When this happens, just can not obtain enough repellences to pressure.
Another traditional method is arranged, wherein a cover front and back panel is heated to seal, place for example stone of weight simultaneously in the central.But this method needs more energy to heat, because the weight on the panel also has been heated.The heating-up temperature of peripheral cell is easy to inhomogeneous.Make large-screen PDP so be difficult to adopt this technology.
Make panel and also have a requirement.General, vacuum pump or aiutage are connected with blast pipe on being connected peripheral cell.By burner or heater blast pipe is reamed subsequently.Need a kind of reliable method to come blast pipe.
An object of the present invention is to provide for example method of PDP of a kind of steady production gas discharge panel, wherein the top of panel and barrier rib all contacts closely.
To achieve these goals, at first, form the peripheral cell of gas discharge panel, then encapsulant is inserted the sealing of carrying out peripheral cell between two panels in edge, adjust pressure simultaneously and make the peripheral cell pressure inside be lower than the pressure of peripheral cell outside.
Adopt the constructive method of said structure, the panel of peripheral cell is bonded together, and they are by from external pressure simultaneously.As a result, the barrier rib top on panel and another panel just is bonded together, and becomes comprehensively contact closely simultaneously.
In order to obtain above-mentioned effect, preferably before sealing material curing, begin to adjust pressure.
The adjustment of pressure can realize by the following method:
(1) form to connect the inside and outside interface channel of peripheral cell, gas is disposed to the outside from the inside of peripheral cell by this interface channel.
(2) use its internal pressure to be lower than the container of peripheral cell internal pressure, reduce the peripheral cell pressure inside.
(3) interrupt the air-flow of peripheral cell between inside and outside; After air-flow interrupts, the peripheral cell pressure inside is adjusted to the pressure (especially reduce the temperature in the peripheral cell, or utilize the gas adsorption effect of gas absorption cell) that is lower than before the air-flow interruption.
(4) after the edge of peripheral cell is sealed, the pressure of peripheral cell outside is modulated to the sealed pressure before in the edge that is higher than peripheral cell.
Can before forming, peripheral cell apply adhesive in the barrier rib top on a panel.The top of another panel and barrier rib is bonded together by adhesive, simultaneously by the edge sealing of encapsulant with peripheral cell.Adopt this constructive method, the barrier rib top on panel and another panel just is bonded together fully, does not wherein have the slit substantially.
In the sealing step or then seal step, to the top of barrier rib emittance for example laser beam or ultrasonic wave, so that the top of panel and barrier rib is bonding.Adopt this method, also the barrier rib top on panel and another panel can be bonded together fully, wherein do not have the slit substantially.
Preferably when exerting pressure, the fastened tools counter plate of clamping panel seals step, to guarantee sealing effectiveness more.In this case, more preferably the resistance to deformation parts are set, are out of shape because of the pressure of fastened tools to prevent panel in the fastened instrument of the panel part of exerting pressure.
Also preferably when being provided with the resist displacement parts that prevent the panel relative displacement, peripheral cell seals.More preferably parts that in face plate edge is provided with anti-encapsulant, flow, thus prevent that encapsulant from flowing into the interior zone of peripheral cell.
In order reliably also easily to ream blast pipe: the hold assembly that can on blast pipe, connect heating element; The hold assembly of this heating element heater block in the place's clamping of distance blast pipe preset distance; Under this condition, start heating element.

In this embodiment, Xe accounts for 5% of discharge gas volume, and the charging pressure of filling discharge gas is the 500-800 torr.
Start PDP to come show image by the circuit block that is connected PDP as shown in Figure 2.
Below describe sealing, exhaust and the discharge gas filling process of embodiment of the present invention 1-10 in detail.Embodiment 1
In the present embodiment, when carrying out seal process, gas is discharged from the inner space of peripheral cell by vacuum pump.
Fig. 3 is the sectional view of the water-tight equipment 50 of this embodiment.Fig. 4 is the perspective view of water-tight equipment 50 shown in Figure 3.
Water-tight equipment composed as follows: combustion furnace 51, be used to lay and heat peripheral cell 40, the front panel 10 and the rear board 20 of this peripheral cell are placed on together; And the vacuum pump 52 that is arranged on combustion furnace 51 outsides.
Combustion furnace 51 is by heater 55 heating.Can be set at temperature desired by the internal temperature of controlling combustion furnace 51.
Utilize water-tight equipment 50 to carry out following seal process.
Shown in Fig. 3 and 4, in advance the edge outside the viewing area of plate 20 forms exhaust outlet 21a in the back.
Apply the thickener that is mixed with encapsulant to one of them or whole edge on plate 10 and rear board 20 surfaces opposite to each other in front.Cure the thickener that applied to form sealant 41.In this embodiment, the softening point low-melting glass that is lower than barrier rib 24 and insulating barrier 23 is used as encapsulant.
For example the low melting point glass paste material package is drawn together 80% low-melting glass material (370 ℃ of softening points), 5% ethyl cellulose adhesive and 15% isoamyl acetate.Sealant 41 can apply thickener by distributor and form.
Front panel 10 and rear board 20 are suitably located facing with each other, and are placed on together to form peripheral cell 40.The edge of peripheral cell 40 is fastening by clip 42, thereby panel can displacement.
Peripheral cell 40 is placed on the inside of combustion furnace 51.Pipe 26 is connected to the exhaust outlet 21a of peripheral cell 40, and vacuum pump 52 connects them.Preferably, manage 26 fastened instruments for example the clip (not shown) be fixed on the rear board 20.
In this embodiment, front panel 10 is placed under the rear board 20 connection to be easy to manage 26.But the position of panel also can be conversely.And peripheral cell can be vertically set in the combustion furnace, as long as panel 10 and 20 can not be produced with displacement and fixedly secure.
Pipe 26 is made by the glass that can bear seal temperature.The pipe 26 exhaust outlet 21a from peripheral cell 40 extend upward, and in certain intermediate point bending, extend and protrusion to the outside by the hole 51a that forms at combustion furnace 51 walls from combustion furnace 51.Pipe 26 expands in its edge's (being called adjoining edge) that is connected to exhaust outlet 21a, and the diameter of adjoining edge is greater than the diameter of exhaust outlet 21a.
Between pipe 26 adjoining edge and rear board 20, add adhesive 26a in advance, thereby they are sealed airtightly.In this embodiment, adhesive 26a and sealant 41 are used identical materials.
The end of pipe 26 is connected to vacuum pump 52.
The inside of combustion furnace 51 is heated to seal temperature (for example 450 ℃), and this temperature is a little more than the softening point of encapsulant.The combustion furnace temperature inside kept 10-30 minute at seal temperature.Combustion furnace 51 inside are cooled then, are lower than the softening point of encapsulant until temperature.Be bonded in together by this process panel 10 and 20.In seal process, gas is discharged from peripheral cell 40 by vacuum pump 52.
Preferably after having reached the softening point of encapsulant, combustion furnace 51 inside begin above-mentioned exhaust process.This is because be not high in the air impermeability of the edge between panel 10 and 20 before combustion furnace 51 inside reach the encapsulant softening point, in case reach softening point, adhesive 26a is softening with gas tight seal pipe 26 and exhaust outlet 21a, and the edge of panel 10 and 20.Therefore, when these parts by after the gas tight seal with gas when peripheral cell 40 is discharged, peripheral cell 40 pressure inside are lowered, and have produced high vacuum (several torr).
After gas is discharged in the inner space of peripheral cell 40, panel 10 is applied identical pressure with 20 from the outside.Regulate the exhaust that vacuum pump 52 carries out, thus peripheral cell 40 pressure inside by with about 5 torrs/minute speed reduce.
When surface 10 when 20 are applied identical pressure from the outside, the top of the barrier rib 24 on the plate 20 and front panel 10 are bonded in together in the back, their become comprehensively contact closely simultaneously, as shown in Figure 3.When the inside of combustion furnace under this condition was cooled, encapsulant also was cooled to the temperature that is lower than its softening point, had caused the sealing of peripheral cell 40.Therefore, in the peripheral cell after seal process, the top of barrier rib 24 becomes all sidedly each other with front panel 10 and definitely contacts.
The adhesive 26a that pipe 26 and rear board 20 are also hardened seals airtightly.
After peripheral cell 40 sealings, remove clip 42, carry out following vacuum exhaust process then.
In the vacuum exhaust process, peripheral cell 40 is placed in the combustion furnace to carry out vacuum exhaust, and vacuum pump is connected to pipe 26, and the inside of combustion furnace is remained on exhaust temperature (for example 350 ℃), this temperature is a little less than the softening point of encapsulant, and the maintenance regular hour (for example 1 hour).
In next procedure, i.e. discharge gas filling process, discharge gas vapour bottle are connected to pipe 26, and the discharge gas of the inner space of unit 40 supply to the periphery is under the charging pressure (for example 400 torrs) until this inner space.When burned or heat fused is reamed when pipe 26 base portion, exhaust outlet 21a sealed (seeing embodiment 14).
Above-mentioned technology can change another kind of technology into, wherein carries out seal process, vacuum exhaust process and the discharge gas filling process of peripheral cell 40 in a firing equipment continuously.For example, in water-tight equipment 50, prepare to provide the vapour bottle of discharge gas, make it be connected to pipe 26.Then, after seal process, peripheral cell 40 is arranged in the combustion furnace 51.Combustion furnace 51 is cooled to exhaust temperature, utilizes vacuum pump 52 to discharge gas from peripheral cell then.In addition, the vapour bottle can be connected to pipe 26, is used to provide discharge gas.
Above-mentioned technology also can be replaced by another technology generations, wherein uses continuous heating equipment to carry out seal process, vacuum exhaust process and discharge gas filling process continuously.For example, vacuum pump and discharge gas vapour bottle, and peripheral cell 40 is added on the dolly that an energy moves in the continuous burning stove.Can utilize vacuum pump to discharge gas, and utilize discharge gas vapour bottle to fill discharge gas, in the continuous burning stove, peripheral cell be heated simultaneously to peripheral cell from peripheral cell.The effect of this method
In routine techniques, the edge of peripheral cell 40 is fastening by clip, and does not have the pressure differential of peripheral cell between inside and outside, does not exert pressure in the central area of peripheral cell.The result is that the barrier rib top on front panel 10 and the rear board 20 is partly bonded together each other discretely.On the contrary, in this embodiment, sealant 41 sclerosis, panel 10 and 20 is applied equal pressure from the outside simultaneously.This makes panel be bonded in together, does not almost have the space between front panel 10 and the barrier rib top.
Therefore the manufacture method of this embodiment is easy to make the PDP with excellent display quality, does not produce vibration when they start substantially.
In order to obtain above-mentioned effect, should start vacuum pump 52, between peripheral cell 40 is inside and outside, to produce pressure differential before beginning sclerosis at softening sealant 41.But extremely finish in the initial of seal process, do not need the operation of vacuum pump 52.For example can obtain this pressure differential by after sealant 41 is softening, starting vacuum pump 52.
In addition, when panel bondd, because inside and outside pressure differential, panel 10 and 20 was pressed each other mutually, utilizes pressure differential sealed periphery unit 40 simultaneously.As a result, by preventing that 42 applied pressures of the required clip of panel displacement just can be lower than the pressure in the conventional method.
Should be pointed out that and to use clip 42 to prevent the displacement of panel 10 and 20.But, use clip to guarantee to prevent displacement.In addition, owing to the clip 42 also sealant 41 at pressed surface panel edges place.Because this pressure, when encapsulant was softening, it is evenly diffusion on the edge.Just sealed the edge airtightly.
Can use different materials as adhesive 26a and sealant 41.But, when as in this embodiment when using identical low-melting glass, sealant 41 and adhesive 26a be softening and sclerosis in the identical time.This means, the sealing of peripheral cell 40 and manage 26 and the gas tight seal of the exhaust outlet 21a of rear board 20 be simultaneously.The change of this embodiment
In this embodiment, use low-melting glass, when adhesive 26a is softening, reduce peripheral cell 40 pressure inside as adhesive 26a.In this case, adhesive 26a may flow into exhaust outlet 21a, thus the sealing between the exhaust outlet 21a of destruction pipe 26 and rear board 20.
In order to prevent the problems referred to above, can use the glass ceramics of crystallization under the temperature lower than sealant 41.This glass ceramics generally is PbO-ZnO-B 2O 3Frit glass.
Glass ceramics in a single day be heated to flow crystallization then and solidify after, even be heated to FCTA temprature once more at it, it can not soften yet.Therefore, because used glass ceramics, just solved above-mentioned problem about sealing as adhesive 26a and slow heating peripheral cell 40.Utilize this mode, glass ceramics can be cured before sealant 41 softens.
By use softening point a little more than the glass of sealant 41 as adhesive 26a, can obtain identical effect.
Using not can be at the softening material (for example softening point is much higher than the glass or the ceramic binder of sealant 41) of the temperature of panel bonding as adhesive 26a, will manage the 26 exhaust outlet 21a that are connected to rear board 20 in advance, can address the above problem.Embodiment 2
This embodiment and embodiment 1 difference are, in seal process, panel 10 and 20 faced with each other and place and form after the peripheral cell 40, sealant 41 outsides of the formation of the edge between panel 10 and 20 form outer sealing layers 43 again, shown in Fig. 5 A and 5B.
Utilize said structure, if defectiveness is gone back in the sealing of sealant 41, this defective can be covered by outer containment layer 43, thereby has guaranteed seal process more.In addition, outer containment layer 43 has reduced the gap between barrier rib top and the front panel 10.
The formation of outer containment layer 43 provides other effect.For example, outer containment layer 43 had been fixed panel 10 and 20 before softening, and prevented that them from leaving original position.And, even before sealant 41 or outer containment layer 43 are softening, also kept inner space air impermeability to a certain degree.As a result, discharge the gas of inner space, can exert pressure to panel 10 and 20 by driving vacuum pump 52.
In order to obtain above-mentioned effect, preferably use identical materials for sealant 41 and outer containment layer 43.For example, the thickener that comprises encapsulant (low-melting glass) that is used as sealant 41 can be applied to sealant 41 outsides of peripheral cell 40, to form outer containment layer 43.
And sealant 41 can form by applying ceramic binder.Embodiment 3
The difference of this embodiment and embodiment 1 is that in plate 10 and the rear board 20 or whole edges form in the zone of sealant 41 in front, form the rib 44 of stream in the anti-encapsulant, as shown in Figure 6A.
By being pre-formed the rib 44 that flows in the anti-encapsulant, when sealant in seal process 41 has melted, and peripheral cell 40 pressure inside can prevent that sealant 41 from flowing into viewing areas when being lower than outside pressure.
The rib 44 of stream has the height roughly the same with barrier rib 24 in the preferred anti-encapsulant.This be because: when rib 44 was higher than barrier rib 24, the gap was formed on the top of plate 10 and barrier rib 24 in front; When rib 44 is more much lower than barrier rib 24, prevent that the effect of stream in the encapsulant from just can not obtain.
The straightforward procedure that forms the rib 44 of stream in the anti-encapsulant is to use barrier rib 24 identical materials on the back glass substrate 21 with rear board 20, forms simultaneously with it, shown in Fig. 6 B.Embodiment 4
The difference of this embodiment and embodiment 1 is, in seal process from the outside to the periphery unit 40 exert pressure, producing peripheral cell 40 pressure differential between inside and outside, and in embodiment 1, reduce internal pressure from the inner space exhaust of peripheral cell.
To achieve these goals, not comprising vacuum pump 52 in the water-tight equipment of this embodiment, may be the combustion furnace 51 of gas tight seal but compression pump 53 is connected to, as shown in Figure 7 in this embodiment.
In the seal process of this embodiment, peripheral cell 40 is utilized compression pump 53 to exert pressure to the inside of combustion furnace 51 by heating in combustion furnace 51 and sealing simultaneously, and the end of pipe 26 is opened to discharge gas from combustion furnace 51.
The above-mentioned encapsulating method of peripheral cell 40 provides the effect identical as enforcement scheme 1, because it is sealed when peripheral cell 40 is accepted ambient pressure.Especially, when carrying out seal process, the internal pressure of peripheral cell 40 remains on atmospheric pressure substantially, and the pressure of peripheral cell 40 outsides is high pressure.Embodiment 5
In this embodiment, use is carried out the sealing of peripheral cell 40 as the water-tight equipment in the enforcement scheme 4 50.But the pipe 26 of this embodiment is linear, does not stretch out combustion furnace 51, its end seal, as shown in Figure 8.
Fig. 9 A is presented at the sealant 41 softening states of peripheral cell 40 before in the seal process, and wherein peripheral cell 40 is sealed by sealant 41, the state after Fig. 9 B demonstration sealant 41 is softening.The seal process of this embodiment is described below with reference to Fig. 9 A and 9B.
At first, soften sealant 41 by heating peripheral cell 40 in combustion furnace 51, the pressure in the combustion furnace 51 remains on atmospheric pressure simultaneously, and compression pump 53 is not opened.
Shown in Fig. 9 A, before sealant 41 softened, gas can flow into and outflow from peripheral cell 40.Therefore, when sealant 41 softened, pressure inside was basic identical with atmospheric pressure.
After sealant 41 and adhesive 26a were softening, compression pump 53 was opened, and exerts pressure in combustion furnace 51.
Shown in Fig. 9 B, after sealant 41 and adhesive 26a were softening, the air-flow between inside and outside the peripheral cell was blocked.When exerted pressure under these conditions in the inside of combustion furnace 51, the inner space of peripheral cell 40 keeps identical with atmospheric pressure substantially, and the pressure of peripheral cell 40 outsides is higher than internal pressure simultaneously.
When the inside of combustion furnace 51 by in above-mentioned high pressure cooling the time, sealant 41 sclerosis, peripheral cell 40 is by in sealing in external pressure.
Can know that from above description the method for this embodiment provides the effect identical as enforcement scheme 1.
Carry out the vacuum exhaust process after the above-mentioned seal process, wherein manage 26 end and cut and open, vacuum pump is connected to this end, and gas space is internally discharged by vacuum pump, to produce vacuum.Embodiment 6
This embodiment is basic identical with embodiment 5, difference is to reduce the internal pressure of peripheral cell 40, and the pressure of peripheral cell 40 outsides is adjusted to atmospheric pressure, and in embodiment 5, the pressure of peripheral cell 40 outsides is raised, peripheral cell 40 pressure inside are maintained at atmospheric pressure, to produce peripheral cell 40 pressure differential between inside and outside.
The structure of the water-tight equipment 50 of this embodiment as shown in Figure 8, difference is to replace compression pump 53 with vacuum pump.
In the seal process of this embodiment, at first open vacuum pump to reduce the pressure in the combustion furnace 51, heating peripheral cell 40 remains on low pressure with the pressure in the combustion furnace 51 simultaneously with softening sealant 41.
Before sealant 41 softened, gas can flow into and outflow from peripheral cell 40.As a result, the inner space of peripheral cell 40 also is in the pressure of reduction when sealant 41 is softening.
After sealant 41 and adhesive 26a are softening, stop vacuum pump, thereby be increased to atmospheric pressure in combustion furnace 51 pressure inside.In this stage, the material that the air-flow between peripheral cell 40 is inside and outside has been softened stops.As a result, the pressure in peripheral cell 40 outsides is higher than pressure inside.
When the inside of combustion furnace 51 is cooled off under these conditions, sealant 41 sclerosis, and at peripheral cell by sealed in external pressure.
The method that is appreciated that this embodiment from foregoing description also provides the effect same with embodiment.Embodiment 7
In this embodiment, the container that its inside is in low pressure is connected to peripheral cell, is disposed to container from this peripheral cell with when keeping the inner low pressure of peripheral cell at gas, and this peripheral cell is sealed.
Figure 10 is the perspective view that utilizes this embodiment sealed periphery unit 40.
In embodiment 1, the edge outside plate 20 viewing areas opens exhaust outlet 21a in the back in advance.And in this embodiment, open exhaust outlet 21b and 21a at the edge.
As implement the scheme 1, plate 10 and rear board 20 lip-deep one or the whole edge that face with each other form sealant 41 in front.Front panel 10 and rear board 20 are suitably located facing with each other, and are placed on together to form peripheral cell 40.The edge of peripheral cell 40 is fastening by clip 42, thereby panel can displacement.
Low internal pressure vessel 70 is connected to the exhaust outlet 21a of peripheral cell 40.The terminal sealed pipe 26 of its of embodiment 5 is connected to exhaust outlet 21a.
Low internal pressure vessel 70 is identical with pipe 26, all is to be made by the glass that can bear seal temperature, and is composed as follows: container body 71; Joint 72 stretches out from container body 71, and is connected to exhaust outlet 21a.Container body 71 is cut off layer 73 gas tight seal (Figure 13 A) by air-flow, and this air-flow cuts off layer 73 and forms in the joint 72 of blocking-up air-flow, and container body 71 pressure inside are maintained at the pressure of reduction.
Adhesive 74 is applied to the joint of the exhaust outlet 21a of joint 72 and rear board 20 in advance.Adhesive 26a is applied to the joint of the exhaust outlet 21b of pipe 26 and rear board 20 in advance.These engage part and are sealed by adhesive airtightly.In this embodiment, the material as sealant 41 also can be used as adhesive 26a and 74.
Be used as air-flow as the material of sealant 41 or its softening point a little more than the low-melting glass of sealant 41 and cut off layer 73, soften simultaneously or after it with sealant 41 and adhesive 26a and 74 thereby layer 73 is basic.
Now, with reference to figure 11A and Figure 11 B the manufacture method of hanging down internal pressure vessel 70 is described.The employing processed glass product for example method of flask is made container body 71 and joint 72.It should be noted that except joint 72 container body 71 is provided with blast pipe 72a, be used for exhaust to produce vacuum.
Shown in Figure 11 A, joint 72 is filled with the thickener that comprises low-melting glass cuts off layer 73 as air-flow material.Air-flow cuts off layer 73, and for example gas burner is softening and make it sclerosis again and form by the thickener heater via.
Shown in Figure 11 B, vacuum pump is connected to blast pipe 72a, utilizes vacuum pump that gas is discharged to produce certain vacuum from container 71.
Shown in Figure 11 C, utilize gas burner to ream blast pipe 72a then, to keep certain vacuum in container body 71, vacuum pump is connected on the blast pipe 72a.
Said process has been finished low internal pressure vessel 70, and its container body 71 has certain vacuum.
Figure 12 represents sealed periphery unit 40 employed band transmission type firing equipments in this embodiment.
Band transmission type firing equipment 60 comprises: the combustion furnace 61 of heating panel, the conveyer belt 62 of transmission peripheral cell 40; The a plurality of heaters 63 that in combustion furnace 61, are provided with along direction of transfer.
Can adjust by a plurality of heaters 63 at inlet 64 and the temperature that exports a plurality of points between 65.Under this structure, peripheral cell 40 can be heated with desirable Temperature Distribution or be cooled off.
Figure 13 A to 13C represents the variation of the state of peripheral cell 40.
The peripheral cell 40 that has low internal pressure vessel 70 and pipe 26 is utilized firing equipment 60 to carry out as lower seal.
Peripheral cell 40 is placed on the conveyer belt 62 of firing equipment 60, and is transmitted in combustion furnace 61.Peripheral cell 40 is heated to and is set at the seal temperature that cuts off the softening point of layer 73 a little more than air-flow, transmits in combustion furnace 61 simultaneously.This adds the speed of pining for the temperature rising is for example 10 ℃/minute.
When the temperature of peripheral cell 40 was lower than the softening point of sealant 41, gas can be at peripheral cell 40 by sealant 41 inflow and outflows.On the other hand, as shown in FIG. 13A, keep the vacuum to a certain degree in the container body 71, because Jin Chu gas is stopped by air-flow cut-out layer 73 from the outside.
When the temperature of peripheral cell 40 owing to heating reaches the softening point of sealant 41, sealant 41 is just softening.Softening sealant 41 gas tight seals panel 10 and 20 edge.Simultaneously, adhesive 26a and 74 softens.As a result, the joint of low internal pressure vessel 70 and rear board 20 and manage 26 and the joint of rear board 20 also sealed airtightly.
Said process has cut off the inner space of peripheral cell 40 and the air-flow between the space outerpace.Especially, between container association that peripheral cell 40 and low internal pressure vessel 70 constitutes inside and outside, interrupt air-flow.
Air-flow cuts off layer 73 substantially when sealant 41 is softening or softening afterwards.When everything took place, because kept vacuum to a certain degree in container body 71, air-flow cut off layer 73 and enters the air-flow of container body 71 by the pressure differential at its opposite side place and from peripheral cell 40 inner spaces and destroy.
The pressure that this has reduced peripheral cell 40 inner spaces makes panel 10 and 20 by from external pressure.
This is exerted pressure and has reduced the slit at front panel 10 and barrier rib 24 tops, shown in Figure 13 C.
Stay peripheral cell 40 and stand seal temperature (for example 30 minutes), cool off then and shift out combustion furnace 61.When peripheral cell 40 is cooled to the softening point that is equal to or less than sealant 41, sealant 41 sclerosis, panel 10 and 20 is by from external pressure simultaneously, and promptly the slit between the top of front panel 10 and barrier rib 24 diminishes simultaneously.
When the heating process of firing equipment 60 finished, joint 72 burned devices reamed to stop exhaust outlet 21b.The end of pipe 26 is cut off, and vacuum tube is connected to pipe 26.Gas is discharged from the inner space of peripheral cell 40, to produce vacuum in the inner space.The effect of the seal process of this embodiment
In this embodiment, as enforcement scheme 1, panel 10 and 20 is bonded in together that they are exerted pressure on an equal basis from the outside simultaneously.The top that is panel 10 and 20 bonded while front panels 10 and barrier rib 24 becomes to contact closely all sidedly.
In embodiment 1, vacuum pump is connected to peripheral cell 40.In embodiment 3-5, the pressure in combustion furnace is lowered or raises.This embodiment does not have such requirement.Under this structure, be easy to use continuous heating equipment for example firing equipment 60 carry out continuous seal and handle.
In the process of making low internal pressure vessel 70, the capacity of preferred container main body 70 and vacuum degree be confirmed as making in the peripheral cell 40 pressure air-flow cut off layer 73 destroyed after between the 10-600 torr.This is because when the pressure in the peripheral cell 40 was lower than 10 torrs, sealant 41 may be destroyed by the pressure differential at its opposite side place; When the pressure in the peripheral cell 40 during greater than 600 torrs, pressure is weak to very little effect only is provided.The change of this embodiment
In this embodiment, air-flow cuts off layer 73 and is made by low-melting glass, thereby it melts because of the heating in the seal process.But air-flow cuts off the material that layer 73 can melt or dissolve by applying light for example or ultrasonic energy and makes.In this case, in seal process energy for example light or ultrasonic wave are applied to this air-flow and cut off layer 73.
For example, air-flow cuts off layer 73 and is made by phenolic resins, and light is radiated in seal process on this phenolic resins.This process can be operated by the mode identical with the present embodiment, and identical effect is provided.Embodiment 8
In this embodiment, seal process is following carries out.Peripheral cell 40 is heated to high temperature, and sealed, thereby the air-flow between inner space and space outerpace is interrupted, and peripheral cell 40 is cooled then, and the pressure in the inner space is lowered, to produce the pressure differential of peripheral cell between inside and outside.
Figure 14 is illustrated in the band transmission type firing equipment that uses in the seal process of this embodiment.Figure 15 is illustrated in the seal process peripheral cell 40 and is placed in the band transmission type firing equipment.
In the seal process of this embodiment, the linear pattern pipe 26 that its end is opened is connected to the exhaust outlet 21a (Figure 15) of peripheral cell 40.Peripheral cell 40 is sealed by band transmission type firing equipment 80 as shown in figure 14.
Firing equipment 80 has the structure identical with the employed firing equipment of embodiment 7 60, but places a burner 81 in combustion furnace 61.This burner 81 is used to heat the end with sealed tube 26.The position of burner 81 in combustion furnace 61 is set at the peripheral cell 40 that conveyer belt 62 transmits in the combustion furnace 61 and arrives maximum temperature (peak temperature) part.
The peripheral cell 40 that has pipe 26 is heated equipment 80 to carry out as lower seal.
Peripheral cell 40 is placed on the conveyer belt of firing equipment 80, and is transmitted in combustion furnace 61.Peripheral cell 40 is heated to the seal temperature (for example 5000 ℃) that is set at the softening point (for example 380 ℃) that is higher than sealant 41, transmits in combustion furnace 61 simultaneously.This adds the speed of pining for the temperature rising is for example 10 ℃/minute.
Stay peripheral cell 40 and stand peak temperature (for example 10 minutes), managing 26 end then is heated and melts with burned device 81 and ream, in this stage, inner space and the air-flow between the space outerpace at peripheral cell 40 have been interrupted because sealant 41 and adhesive 26a melt, shown in Figure 19 B in the enforcement scheme 5.Be that the inner space is sealed airtightly.
Be cooled through after the burner 81 at peripheral cell 40, in combustion furnace 61, transmit simultaneously, shift out combustion furnace 61 then.Pressure and absolute temperature in the gas tight seal space proportional (Bolye-Charles law).As a result, the pressure of peripheral cell 40 inner spaces is thereupon the reduction of temperature and descend.This produces pressure differential between inner space inside and outside, make panel 10 and 20 by from external pressure.When the peripheral cell 40 that is moved out of combustion furnace was further cooled softening point to sealant 41, sealant 41 and adhesive 26a began sclerosis.Be that panel 10 and 20 is bonded, the slit between the top of plate 10 and barrier rib 24 is little in front.Pipe 26 also is bonded to rear board 20.
Is the vacuum exhaust process after the seal process as above, wherein manages 26 end and be cut off and open that vacuum pump is connected to this end, gas is discharged to produce vacuum in the space internally by vacuum pump.The effect of this embodiment seal process
In this embodiment, as enforcement scheme 1, panel 10 and 20 is bonded in together that they are exerted pressure on an equal basis from the outside simultaneously.The top that is panel 10 and 20 bonded while front panels 10 and barrier rib 24 becomes to contact closely all sidedly.Under this structure, be easy to use continuous heating equipment for example firing equipment 80 carry out the continuous seal step.
Should be pointed out that in order to produce enough effects, need be when sealant 41 sclerosis between the outside of peripheral cell 40 and internal pressure, have enough pressure differentials.The end of pipe can (peak temperature) be cut off under high 10 ℃ and preferred high tens ℃ temperature than the softening point of sealant 41 thus.The change of this embodiment
In this embodiment, 81 heating of pipe 26 terminal burned device and sealing are to be breaking at peripheral cell 40 air-flow between inside and outside.But also can use following method.
The end of pipe 26 is filled with low-melting glass in advance, and its softening point is a little less than above-mentioned peak temperature.Under this arrangement, low-melting glass is the just softening also end of sealed tube before peripheral cell arrives peak temperature, has omitted the needs with burner 81 combustion tube ends.When the temperature of peripheral cell 40 begins when peak temperature descends, softening rapidly at the low-melting glass that pipe is terminal.When the temperature of peripheral cell 40 further descends and reaches the softening point of sealant 41, just produced the pressure differential between peripheral cell 40 outsides and the inside.The effect of this embodiment can be produced by this change as a result.
Perhaps, as enforcement scheme 7, open exhaust outlet 21b and exhaust outlet 21a in the back in the plate 20, the linear pattern pipe 26 of its end seal is connected to exhaust outlet 21b.Herein, exhaust outlet 21a still opens, and does not connect anything.
When peripheral cell 40 reached peak temperature, its softening point was splashed in the exhaust outlet 21a a little less than the low-melting glass of this peak temperature, with sealing exhaust outlet 21a.In this case, as above-mentioned change, begin after peak temperature descends at peripheral cell 40, low-melting glass hardens rapidly.When the temperature of peripheral cell 40 further descends and reaches the softening point of sealant 41, just produced the pressure differential between peripheral cell 40 outsides and the inside.The effect of this embodiment also can be produced by this change as a result.Embodiment 9
In this embodiment, use the container association that constitutes by peripheral cell 40 and container.In the sealing process, heating container association is to high temperature, and the air-flow between this container association outside and inside is interrupted at this high temperature, and peripheral cell is cooled simultaneously that the peripheral cell internal pressure is a low pressure, and peripheral cell is sealed as a result.
Figure 16 A to 16C represents the sealing of the peripheral cell 40 of this embodiment.
Shown in Figure 16 A, comprise putting together and wherein having the front panel 10 of sealant 41 and the peripheral cell 40 of rear board 20 to be placed in the combustion furnace 51, as enforcement scheme 1.The difference of this embodiment and embodiment 1 is that the container 90 that its end is opened is connected to the exhaust outlet 21a of rear board 20, has replaced pipe 26.
Container 90 is composed as follows: container body 91; Joint 92 from container body 91 stretches out connects container body 91 and exhaust outlet 21a; Extension 93,91 extend along the direction opposite with joint from container body, and its end is opened.
In the initial device of seal process, container 90 is connected to exhaust outlet 21a, and container body 91 exposes the outside at combustion furnace 51 to the open air.Between joint 92 and rear board 20, apply adhesive 94 in advance, thereby the joint of container 90 and rear board 20 is sealed airtightly.In this embodiment, be used for sealant 41 identical materials, as adhesive 94.
The electric heater 95 of heating container main body 91 is connected to container body 91.
Before above-mentioned initial installation was finished, peripheral cell 40 was heated above the temperature (for example 480 ℃, add at this to pine for rate of rise in temperature be for example 10 ℃/minute) of sealant 41 softening points in combustion furnace 51.Simultaneously, container body 91 is heated to selected temperature (for example 200 ℃) by electric heater 95.The terminal burned device sealing of extension 93 then.
Herein, shown in Figure 16 B, the end of extension 93 is sealed, and sealant 41 and adhesive 94 are softening.As a result, the air-flow of air-flow between peripheral cell 40 outsides and inside and container body 91 inside and outside (spaces in the combustion furnace 51) is interrupted.
Turn off electric heater 95 then, with cooled containers main body 91, peripheral cell 40 is maintained at the temperature of the softening point that is higher than sealant 41 in combustion furnace 51 simultaneously, shown in Figure 16 C.
The temperature of container body 91 reduces the reduction that has caused the pressure in the container body 91, and this has caused the reduction of the pressure in the peripheral cell 40.Therefore, as embodiment 8, between the outside of peripheral cell 40 and inside, produce pressure differential.Make panel 10 and 20 by from external pressure.
Temperature in the combustion furnace 51 descends then.When peripheral cell 40 is cooled to the softening point of sealant 41, sealant 41 and adhesive 94 sclerosis.Be that panel 10 and 20 is bonded, leave small gap between the top of front panel 10 and barrier rib 24.Container 90 also is bonded to rear board 20.
After the above-mentioned seal process is the vacuum exhaust process, and wherein the end of extension 93 is cut off and opens, and vacuum pump is connected to this end, and gas is discharged to produce vacuum in the space internally by vacuum pump.The effect of this embodiment seal process
In this embodiment, as embodiment 8, panel 10 and 20 is bonded in together, and the top of front panel 10 and barrier rib 24 becomes to contact closely all sidedly simultaneously.
In embodiment 8, peripheral cell 40 self is cooled with reduction pressure, and in this embodiment, the pressure of peripheral cell 40 inner spaces reduces because of the temperature of container 90, and its temperature that is arranged so that of this container 90 can be separated adjustment.As a result, different with embodiment 8, peripheral cell 40 does not need to be heated to the temperature that is much higher than sealant 41 softening points.In this embodiment, it is just enough that peripheral cell 40 is heated to the temperature identical or higher with the softening point of sealant 41.Embodiment 10
In this embodiment, use continuous heating equipment to heat the described container of embodiment 9 association.In the sealing process, container association is heated to high temperature, and the air-flow between container association is inside and outside is interrupted at high temperature, and peripheral cell is cooled, and the pressure in the peripheral cell is low pressure simultaneously, and peripheral cell is sealed as a result.
Figure 17 represents the band transmission type firing equipment of sealed periphery unit 40 uses in this embodiment.Figure 18 is illustrated in the seal process peripheral cell 40 and is placed in the band transmission type firing equipment.
In the seal process of this embodiment, as embodiment 8, be heated by the peripheral cell 40 that adhesive 94 is connected with container 90 by exhaust outlet 21a, in firing equipment 100, transmit simultaneously, thereby peripheral cell 40 is sealed, as shown in figure 17.
Firing equipment 100 has the structure identical with the firing equipment that uses 80 in the embodiment 8, but the burner 101 of extension 93 ends of airtight container 90 is set in the combustion furnace 61.This burner 101 position in combustion furnace 61 is set at the peripheral cell 40 that is transmitted by conveyer belt 62 and arrives the zone that is equal to or greater than seal temperature (softening point of sealant 41) in combustion furnace 61.
In firing equipment 100, top board 61a is reduced to the height between burner and the outlet.Top board 61a has groove 61b, thereby the joint 92 of container 90 can pass through it when peripheral cell 40 transmits on tape.Top board 61a also has window 61c, thereby container body 91 can pass through it when peripheral cell 40 transmits on tape.
The peripheral cell 40 that has container 90 is placed on the conveyer belt 62 of firing equipment 100, and is transmitted in combustion furnace 61.Peripheral cell 40 is heated to seal temperature, and is left at seal temperature and bears a period of time.Terminal burned device 101 heating of extension 93 are with sealed simultaneously.
In this stage, peripheral cell 40 is in the identical state of Figure 16 B of embodiment 9.The end that is extension 93 is sealed, and sealant 41 and adhesive 94 are softening.As a result, air-flow between peripheral cell 40 inside and outside and the air-flow between container body 91 inside and outside are interrupted.
After passing through burner 101, peripheral cell 40 is maintained at and the identical or higher temperature of sealant 41 softening points, because it is moved in the combustion furnace 61, simultaneously being cooled, because it is in the outside of combustion furnace 61 (on the top board 61a) by container body 91 after the window 61c.
The temperature of container body 91 reduces the reduction that has caused the pressure in the container body 91, and this has caused the reduction of the pressure in the peripheral cell 40, as the state of the embodiment 9 shown in Figure 16 c.This produces pressure differential between the outside of peripheral cell 40 and inside.Make panel 10 and 20 by from external pressure.
When peripheral cell 40 is cooled to the softening point of sealant 41, sealant 41 and adhesive 94 sclerosis.Be that panel 10 and 20 is bonded, leave small gap between the top of front panel 10 and barrier rib 24.Container 90 also is bonded to rear board 20.Peripheral cell 40 is moved out of combustion furnace 61 then.
After the above-mentioned seal process is the vacuum exhaust process, and wherein the end of extension 93 is cut off and opens, and vacuum pump is connected to this end, and gas is discharged to produce vacuum in the space internally by vacuum pump.
Preferably during the temperature in keeping combustion furnace 61, window 61c is provided with adjustment doors, and this adjustment doors is just opened during by window 61c at container body 91.The change of inner space decompression method

This embodiment and embodiment 1 are basic identical, but before forming peripheral cell 40, form articulamentum 45 in the back on the top of the barrier rib 24 on the plate 20.Articulamentum 45 connects barrier rib 24 and front panel 10.
Be used for the material of articulamentum 45 and should not can the operation of PDP be produced bad influence, and need have the ability that connects barrier rib 24 and front panel 10.In this embodiment, the low-melting glass that is used for sealant 41.
Contain the thickener that connects material (low-melting glass), cure the thickener that is applied then and form articulamentum 45 by adopting method for printing screen to apply to the top of barrier rib 24.
Form articulamentum 45 at first, as mentioned above.Between peripheral cell 40 outsides and inside, produce pressure differential then, make pressure inside be lower than external pressure, as embodiment 1.This makes airtight 10 and 20 to be exerted pressure from the outside with being equal to.In this stage, the top of front panel 10 and barrier rib 24 becomes to contact closely all sidedly.When sealant 41 and articulamentum 45 hardened under this condition, front panel 10 closely was connected with the top of barrier rib 24.
The PDP that adopts the method for this embodiment to make, wherein the top of front panel 10 and barrier rib 24 is connected comprehensively, just limits the vibration that PDP starts and improves the PDP display effect, and it is better than the PDP of embodiment 1 greatly.
In this embodiment, the technology that forms articulamentum 45 in advance on the top of barrier rib 24 is based on that embodiment 1 describes.But this technology also can be used for embodiment 2-10.When in embodiment 2-10, on the top of barrier rib 24, forming articulamentum 45, just limit the vibration that PDP starts and improve the PDP display effect, adopt the PDP of these method manufacturings to be better than the PDP that in embodiment 2-10, makes greatly, because the top of front panel 10 and barrier rib 24 becomes to be connected all sidedly, and can fill discharge gas at high pressure for the inner space.Embodiment 12
This embodiment is basic identical with embodiment 1, but before seal process, and plate 10 and rear board 20 one of them or two edges will form near formation resistance to deformation ribs 46 zone of sealant 41 in front, shown in Figure 20 A and 20B.
In the embodiment shown in Figure 20 A, along the outside formation resistance to deformation rib 46 of sealant 41.In the embodiment shown in Figure 20 B, outside and the inside along sealant 41 forms resistance to deformation rib 46a and 46b respectively.
Adopt this layout,, also can prevent their distortion even when panel 10 and 20 is exerted pressure by clip 42 at its edge.
When this resistance to deformation rib does not form near sealant 41, when sealant 41 is softening in seal process, as described below the acting on panel 10 and 20 of pressure that provides by clip 42.Shown in Figure 20 D, at the edge of peripheral cell 40, panel 10 and 20 is easy to because of close to each other the distortion (direction shown in the arrow A in the drawings).When these took place, panel 10 and 20 was easy to be out of shape (in the drawings direction arrow B shown in) because of distance each other by leverage in the center.This effect is not preferred, because they have widened the slit between front panel and barrier rib 24 tops.
On the other hand, when forming resistance to deformation rib 46 as mentioned above, even when sealant 41 is softening in seal process, panel 10 and 20 also can not produce distortion because of the pressure of clip 42.
Therefore it can strengthen the effect that reduce in the slit between front panel 10 and barrier rib 24 tops.
Perhaps, can make the pressure spot of each clip be placed in face plate edge inside, especially make clip 42 be pressed in the image viewing area, and prevent panel 10 and 20, shown in Figure 20 C because the pressure of clip 42 produces distortion by clip 42 is set.
In the embodiment shown in Figure 20 B,, also has the effect that prevents softening sealant 41 inflow viewing areas when externally pressure is higher than internal pressure along the inside and outside formation resistance to deformation rib of sealant 41.Be that resistance to deformation rib 46b is also as the rib 44 that flows in the anti-encapsulant of describing in embodiment 3.
When panel 10 and 20 is placed on when facing with each other together, the resistance to deformation rib 46 that is preferably formed has the height identical with barrier rib 24.
This be because: when rib 46 is higher than barrier rib 24, produce the slit between plate 10 and barrier rib 24 tops in front; When rib was significantly less than barrier rib 24, just expectability did not have the effect that prevents panel 10 and 20 distortion.
A kind of straightforward procedure that forms resistance to deformation rib 46 is, uses barrier rib 24 identical materials on the back glass substrate 21 with rear board 20, and formation synchronous with it is as forming the rib 44 that flows in the anti-encapsulant.
Figure 21 A-21F is the part front view, is illustrated in the shape of the resistance to deformation rib 46 that forms on the rear board 20.In these figure, hatched example areas C indicates to form the zone of sealant 41.
In Figure 21 A, resistance to deformation rib 46a and 46b form with straight line along the outside of hatched example areas C and inside.
In Figure 21 B, a plurality of resistance to deformation ribs form in the hatched example areas C that intersects with them with the gap of rule.
In Figure 21 C, a plurality of resistance to deformation ribs form in hatched example areas C at random.
In Figure 21 D, a plurality of short resistance to deformation rib 46a oblique formation in hatched example areas C, resistance to deformation rib 46b forms with straight line along zone C inside.
In Figure 21 E, resistance to deformation rib 46a forms with dash line along hatched example areas C outside, and resistance to deformation rib 46b forms with straight line parallel along zone C inside.
In Figure 21 F, a plurality of resistance to deformation rib 46a form in the hatched example areas C that intersects with them with the gap of rule, and resistance to deformation rib 46b forms with straight line parallel along zone C inside.The change of this embodiment
The technology of Pi Luing for example forms the technology of resistance to deformation rib 46 or presses the technology of image viewing area can be used to the seal process of general manufacturing PDP by clip in the above-described embodiment, be not limited to peripheral cell and produce the seal process of pressure differential between inside and outside, thereby pressure inside is lower than external pressure.Embodiment 13
In this embodiment, energy by radiation consumingly at the barrier rib top with the top and the front panel of the barrier rib that after carrying out seal process, bonds according to a kind of mode among the above-mentioned embodiment 1-10.
Figure 22 A-22C represents the process by laser beam radiation bonding barrier rib top and front panel.
At first, front panel 10 and rear board 20 are placed on together forming peripheral cell 40, and softening and subsequently the sclerosis of panel by sealant 41 is and bonded, and the method for employing is the method (Figure 22 A) described in the embodiment 1-10.
The second, shown in Figure 22 B, by the front panel 10 of the peripheral cell 40 that formed, laser beam is radiated to the top of barrier rib from laser process equipment 200.
As described below, laser process equipment 200 comprises a plurality of parts, its laser beam radiation as described below.YAG laser oscillator 201 is to laser head 203 pulse that gives off laser beam, and the vertical and level (directions X in Figure 22 B and Y direction) of laser head 203 scans workpiece (peripheral cell 40) simultaneously.Convergent lens 204 is arranged in the laser head 203, and the convergent laser bundle becomes ellipse light spot to the surface of workpiece.
When laser beam was radiated through the top of barrier rib, this top was heated above the temperature of the softening point (for example 500-600 ℃) of barrier rib material consumingly.When these took place, this material softening (fusion) was with after-hardening.This makes the top adhesive of front panel and barrier rib be in the same place, because they have become close contact by this.
Therefore, length direction along peripheral cell 40 moves laser beam radiation on the barrier rib top by scanning direction barrier rib top shown in Figure 22 B arrow, and the top of front panel and barrier rib is bonded together (hatched example areas among the figure is represented bonded areas) all sidedly.
Figure 22 C represents the sequence in the spot bond zone (hatched example areas among the figure) that forms by the intermittent radiation laser beam.But bonded areas can be by with very short laser beam radiation discontinuously or continuous radiation laser beam and straight line forms.
Even between peripheral cell 40 is inside and outside, not having pressure differential, the top of front panel and barrier rib also can form by laser beam radiation as mentioned above.But, preferably under the pressure that keeps the peripheral cell inner space is lower than the pressure status of space outerpace, carry out seal process, as implementing as described in scheme 1-5 and the 7-10.This is because of the top of front panel and barrier rib and bonds together that their become contact closely simultaneously.
Figure 23 is the perspective view of specific laser process equipment 200.
Laser process equipment 200 shown in Figure 23 is gate-types.In this laser process equipment 200, platform 202 is supported for and can moves at directions X, as shown in figure 23.Form arched door 210 and stride across platform 202.Laser blowtorch 211 is supported on the arched door 210 moving in the Y direction.Laser blowtorch 211 and platform 201 are accurately driven by the stepping motor (not shown).
Peripheral cell 40 is fixed on the platform 202 by vacuum chuck mechanism.
Laser head 203 is fixed on the laser blowtorch 211.The fiber optic cables 212 that the laser beam that sends from laser oscillator 201 is made by quartz glass are directed to laser head 203.Preferably, laser oscillator 201 is achieved in that the YAG laser oscillator 201 that can send strong beam at short notice; Or CO 2Laser oscillator.The output of laser oscillator is 10mW for example.
At first, peripheral cell 40 is placed on the platform 202, makes each barrier rib extend along directions X, as shown in figure 23.By move the hot spot of laser beam radiation along directions X at the top of barrier rib, first barrier rib is bonded on the front panel then.This hot spot moves along the Y direction according to the spacing of barrier rib.Barrier rib for remainder repeats this process, and is bonded until the entire top of barrier rib.The effect of this embodiment
In this embodiment, the top of front panel and barrier rib is all bonded together.As a result, be limited in vibration and the effect of improving the PDP display quality and the embodiment 11 same excellences that PDP starts.
The experimental result that drives the PDP of this embodiment manufacturing of employing and carry out shows the resonance that barrier rib and front panel can not take place, and this resonance exists in traditional product.And the result shows that the noise level of the PDP of this embodiment is 1/10th of a traditional product, does not crosstalk between the chamber.
This embodiment also has another and different advantages such as embodiment 11, and promptly the top adhesive of front panel and barrier rib need not the top coating adhesive to barrier rib together, and the result has simplified manufacturing process.
According to the method for this embodiment, the top of front panel and barrier rib is blocked the material of rib rather than adhesive and bonds together.This has brought advantage.When the image viewing area of PDP comprised adhesive, adhesive can discharge impurity and enter discharge gas.But, in the PDP of this embodiment manufacturing, just do not have this possibility.
But, also can form articulamentum 45 at the top of barrier rib 24 in advance as embodiment 11, after forming peripheral cell 40, laser beam radiation is with the top of bonding front panel and barrier rib, as this embodiment on articulamentum 45 then.This method has been guaranteed bonding, although can not obtain above-mentioned advantage.
Note more safely to bond when the material that improves laser beam absorption for example during the material mixing of black filler and articulamentum 45.The change of this embodiment

Controller 208 also utilizes the barrier rib positional information of being stored and at Y directional trim laser head 203, thereby when laser head 203 during at directions X scanning barrier rib, bombardment with laser beams is in the accurate center of each barrier rib.
Even this arrangement has guaranteed that laser beam also can be radiated through the center of each barrier rib when barrier rib 24 lacks for shaped form (snakelike) or part, front panel and barrier rib are highly precisely bondd as a result.
Perhaps, utilize laser process equipment shown in Figure 24 200, intensity of laser beam can be regulated by the width of monitoring barrier rib or the reflectivity of laser beam.
When soften because of laser beam radiation at the top of barrier rib, think that barrier rib is wide more or reflectivity is high more, the temperature that raises because of laser emission is few more, and bonded areas is more little.On the contrary, when articulamentum forms at the top of barrier rib, can when barrier rib is wideer, increase bonded areas, also increase because connect the consumption of material.Therefore, when the radiation intensity of laser beam fixedly the time, bond state (zone of barrier rib fusion) is easy to each position at barrier rib top is changed with the width of rib or the change of reflectivity.
By control the radiation intensity or the angle of radiation of laser beam according to the width that monitors at the top of barrier rib or the reflectivity that monitors, can address the above problem.
In this embodiment, carry out after seal process because of the bonding process that laser beam radiation bonds at the top of front panel 10 and barrier rib 24, and the peripheral cell pressure inside keeps below outside pressure in the sealing process.But the bonding process can be carried out after the seal process of routine.Although in this case, bonding is considered to poorer than this embodiment, because they are bonded, between the top of plate 10 and barrier rib more slit is arranged in front simultaneously.
In this embodiment, carry out after seal process because of the bonding process that laser beam radiation bonds at the top of front panel 10 and barrier rib 24.But it is should the bonding process can before seal process, carry out, or parallel with it.
When the bonding process was carried out before seal process, for whole panels, preferably the edge of peripheral cell 40 is sealed by the outer containment layer as enforcement scheme 2, and panel is bonded then, discharges gas to reduce internal pressure from the inner space of peripheral cell 40 simultaneously.
In this embodiment, the top of barrier rib or adhesive are softened (fusion) by the bombardment with laser beams on it.But can be because of the ultrasonic wave for example of emittance on the top of barrier rib, or utilize the powerful heating of heater front panel 10, and make the top of barrier rib or adhesive softening.
Perhaps, can be by front panel and rear board be put together, front panel has been heated and has surrounded the softening point of barrier rib 24 simultaneously, makes the top of barrier rib or adhesive contact with front panel 10, and front panel is softened with bonding front panel and barrier rib, and forms peripheral cell 40.Embodiment 14
