Description

  The present invention relates to a technique for manufacturing a gas discharge panel using gas discharge such as a plasma display panel (PDP), and more particularly to sealing (sealing) of a panel.

  In manufacturing a conventional PDP (hereinafter also simply referred to as a panel), a panel sealing (sealing) step is included. A space (discharging space) inside the panel is formed by being sandwiched between a pair of front and back substrates (structural structures) that mainly constitute the panel. Seal the specified part outside the panel so that there is no leakage from the space inside the panel, and evacuate and fill the discharge gas while maintaining the airtightness inside the panel through the specified part communicating with the outside of the panel. -A series of processing steps are required for hermetically sealing by enclosing and closing. At this time, as a part to be sealed, basically, a peripheral part (outer edge part) between the substrates of the panel, and a pipe part for exhausting / sealing etc. arranged at any part such as one corner of the panel (Tip tube).

  The chip tube is attached to a hole (a vent hole) of the substrate of the panel for a series of processing steps between the panel internal space and the outside. In the sealing of the peripheral portion of the panel, for example, the sealing material disposed in the peripheral portion between the substrates is fixed by heat treatment. In the sealing of the chip tube, for example, the sealing is performed by heat-treating a sealing material (such as an adhesive) disposed between the hole of the substrate and the end of the chip tube.

  Moreover, in the process of sealing the conventional panel, sealing is assisted by fixing the peripheral part of the panel using, for example, a clip having an elastic structure. Further, the tip tube is also disposed on the outside facing surface at a position corresponding to the hole portion of the substrate, particularly through the sealing material, and is fixed by using a clip.

  Conventionally, the tip tube is also sealed to the hole of the panel at the same time as the sealing of the peripheral portion of the panel.

Japanese Patent No. 3422175 (Patent Document 1) describes a technical example of panel sealing using a pipe part and a clip as described above.
Patent No. 3422175

  In the conventional PDP, the chip tube is fixed to the panel with a clip in order to prevent the chip tube from falling off in the method and structure for sealing the chip tube outside the panel (surface facing the substrate outside). This complicates the structure of a manufacturing apparatus, that is, a machine that performs automatic panel manufacturing operations such as fixing and sealing of substrates, chip tubes, clips, and the like, resulting in high costs.

  In addition, the fixing with the clip related to the sealing of the panel and the tip tube is relatively unreliable due to its shape and mechanism, etc., and there is a possibility of leakage of the sealing portion, thereby reducing the yield. I was invited.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a tube portion (tubular shape) necessary for a process between the inside and the outside of a gas discharge panel such as a PDP. It is an object of the present invention to provide a technique capable of improving the fixing and sealing performance of the member and realizing simplification of the manufacturing apparatus and cost reduction.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows. In order to achieve the above object, the present invention is a technique of a gas discharge panel such as a PDP and a method for manufacturing the same, and includes the following technical means and structure.

  The gas discharge panel is mainly composed of a pair of front and back substrates (substrate structure), and a peripheral portion between the substrates is sealed to form a space inside the panel (discharging space) sandwiched between the substrates. ) Is configured. The front and rear substrates have a first surface facing the inside of the panel, that is, a surface on which a structure such as a partition wall is formed or arranged facing the discharge space, and a second surface facing the outside of the panel, that is, the panel surface or And a back surface. On one substrate (first substrate), a tubular member (chip tube) serving as a tube portion for a processing process between the inside and outside of the panel is attached. The first substrate is provided with a hole (exhaust hole) communicating with the first and second surfaces corresponding to the position where the tubular member is attached. For example, a hole is provided in the periphery of the substrate on the back surface, and the end of the tubular member is attached to the surface near the hole. The tubular member has, for example, a shape having a trunk portion, a first end portion opened on the panel connection side, and a second end portion on the panel non-connection side.

  In this gas discharge panel and its manufacturing method, unlike the conventional configuration in which the tubular member is attached to the outer surface of the panel, the tubular member is formed to the inner surface of the panel through the hole of one substrate (first substrate). It is the structure to which a member is attached. That is, the first end portion having a shape extending outward from the trunk portion of the tubular member is fixed to the first surface side of the hole portion of the first substrate, and the trunk portion and the second portion of the tubular member are passed through the hole portion. It is the structure attached so that the edge part of this may be inserted and it may come out of a panel from the 2nd surface side.

  As the manufacturing method, for example, in the step before the front and rear first and second substrates are connected to face each other, the second end of the tubular member is passed through the hole on the first surface side of the first substrate. Alignment and fixing are performed so that the first portion and the backbone portion come out to the second surface side (outside of the panel) of the first substrate and the first end portion comes to the first surface side. In addition, a second sealing material for connecting them is disposed between the surface of the first substrate near the hole and the surface of the first end of the tubular member.

  And in the said arrangement | positioning state, the said site | part containing the 1st edge part and 2nd sealing material of a tubular member is fixed by heat processing. That is, the second sealing material is heated to its softening point (T2) or higher and melted, and then solidified by lowering the temperature, so that the first end of the tubular member is a surface near the hole of the first substrate. Connect to. Thereafter, the front and rear first and second substrates are overlapped, and the first sealing material disposed in the peripheral portion of the substrate is heated to the softening point (T1) or more, thereby the panel peripheral portion is Seal. For example, the softening point (T2) of the second sealing material on the tubular member side is configured to be higher than the softening point (T1) of the first sealing material on the panel peripheral side (T2> T1).

  With the above configuration, the first end portion of the tubular member is attached to the first surface side of the first substrate, so that fixing means by a conventional clip or the like is not required, and the tube portion can be fixed and The sealing performance is improved.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows. According to the present invention, in a gas discharge panel such as a PDP, it is possible to improve the performance of fixing and sealing a tube portion required for a process between the inside and outside of the panel, simplifying the manufacturing apparatus, and Cost reduction can be realized.

  In particular, since the tip tube is fixed to the substrate surface on the inner side of the panel, the tip tube does not fall off, for example, when the panel is moved or heat-sealed in the manufacturing apparatus. It becomes unnecessary.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted. FIG. 9 shows a configuration of a prior art example for easy understanding in comparison with the present invention.

(Embodiment 1)
With reference to FIGS. 1-5, the structure of PDP10 in Embodiment 1 of this invention is demonstrated.

<PDP front>
First, in FIG. 1, a schematic configuration viewed from the front (display screen) side of the PDP 10 will be described. The AC type PDP 10 is mainly configured by combining a structure (also referred to as an assembly) of a front substrate 201 and a rear substrate 202, each of which mainly includes a glass substrate and on which an electrode group is formed. A space between the front substrate 201 and the rear substrate 202 is sealed by a panel sealing portion (first sealing material) 203 disposed in the peripheral portion of the panel.

  The display area 110 inside the panel sealing portion 203 is an area where an image is displayed corresponding to an address / display cell matrix constituted by various electrode groups. Outside the panel sealing portion 203, there is a region for electrical connection between the terminals of the electrode group and the external drive circuit side.

  The hole 125 is used in a series of processing steps such as ventilation between the panel internal space and the outside, and is a place where the tip tube (300) is attached. The hole 125 may be provided at any position as long as it is between the display region 110 and the panel sealing portion 203, but in this example, the hole 125 is provided at one corner on the back substrate 202 side. .

  The PDP 10 is further fixedly held with respect to the chassis disposed on the back side thereof, and a circuit unit such as a drive circuit configured on the back side of the chassis is connected to terminals of the electrode group of the PDP 10, so that the PDP device (PDP module) is configured.

<PDP cross section>
Next, referring to FIG. 2, a schematic configuration of a cross section of the PDP 10 will be described. FIG. 2 shows a cross section in the horizontal (row) direction of the PDP 10 of FIG. 1 as an example. The same concept applies to the cross section in the longitudinal (column) direction. FIG. 2 shows a configuration before the tip tube (300) is attached to the PDP 10.

  The discharge space 19 between the front substrate 201 and the rear substrate 202 is sealed by a panel sealing portion 203 disposed and formed in the peripheral portion 120 of the PDP 10. A hole 125 is formed in a part of the back substrate 202 so as to communicate between the inside of the panel and the outside of the panel.

  On the front substrate 201 side, a plurality of X electrodes 11 and Y electrodes 12 that are display electrodes (sustain electrodes) are formed in the lateral direction on the front glass substrate 1 toward the discharge space 19 and extend in the horizontal direction. Further, it is covered with a dielectric layer and a protective layer. Further, on the back substrate 202 side, a plurality of address electrodes 13 used for the address operation are formed to extend in the vertical direction on the inner surface facing the discharge space 19 on the rear glass substrate 2, and further a dielectric layer or the like. Covered by. Furthermore, on the inner surface of the back substrate 202, the barrier ribs 18 that divide the discharge space 19 and structures such as phosphors (not shown) formed between the barrier ribs 18 are formed.

<Example of conventional technology>
Next, in FIG. 9, before describing the characteristics of the present embodiment, the structure and manufacturing method of the PDP of the prior art example will be briefly described. In FIG. 9A, this conventional panel includes a front substrate 201 and a rear substrate 202 combined, and the peripheral portion of the panel is sealed with a panel sealing portion (first sealing material) 203. Inside the panel sealing portion 203, a hole 125 is provided at one corner of the back substrate 202 to communicate with the space 150 inside the panel and the outside.

  An end portion (first end portion) of one opening of the tip tube 300 is attached to an outward facing surface in the vicinity of the hole portion 125 in the back substrate 202. The first end portion (base end portion) of the tip tube 300 on the panel connection side corresponds to the fixing to the outward facing surface in the vicinity of the hole 125, for example, a flange (flange) shape as shown in FIG. Or have a flare shape. A second sealing material 303 serving as a tip tube sealing portion is interposed between the outward facing surface in the vicinity of the hole portion 125 and the surface of the first end portion of the tip tube 300, and the second sealing material. By fixing 303, the tip tube 300 and the back substrate 202 are sealed.

  Through the tip tube 300 and the hole 125, a process such as evacuation and discharge gas filling is performed on the space 150 inside the panel. Eventually, the end (second end) of the other opening of the tip tube 300 is closed (chip off), so that the space 150 inside the panel corresponding to the discharge space 19 is closed.

  When the tip tube 300 is attached, the second substrate 303 and the tip tube 300 are aligned and fixed with respect to the hole 125 by arranging the rear substrate 202 having the hole 125 on the upper side. At that time, the tip tube 300 and the second sealing material 303 are fixed to the rear substrate 202 of the panel using a clip. As shown in FIG. 9B, the region excluding a part of the first end portion (collar portion) of the tip tube 300 is sandwiched and fixed together with the rear substrate 202 and the front substrate 201 by the clip support portion 400. . The main body (main part) of the tip tube 300 is inserted through the insertion part of the clip. After the tip tube 300 and the rear substrate 202 are sealed with the second sealing material 303, the clip is removed.

  The first end portion of the tip tube 300 is generally fixed by the clamping force of the clip, but the weight for fixing the clip to the region of the first end portion of the tip tube 300 from the shape and mechanism of the clip. Are not evenly added. That is, conventionally, the fixing performance of the tip tube 300 is not 100%.

  Although the above process can be performed almost automatically using a manufacturing apparatus, the fixing work using a clip is relatively complicated, and the manufacturing apparatus is complicated, and the cost is high.

<Tip tube and hole>
Next, a characteristic configuration of PDP 10 in the first exemplary embodiment of the present invention will be described with reference to FIGS. FIG. 3A shows a cross section in a state where the tip tube 300 is attached to the hole 125 of the PDP 10. FIG. 3B shows a configuration example of the tip tube 300 corresponding to FIG.

  3A, in the PDP 10, the tip tube 300 is connected to the back substrate 202 on the side provided with the hole 125 from the first surface (a) side facing the space 150 and the structure inside the panel. It is attached so as to pass through 125 toward the second surface (b). The chip tube 300 is sealed by fixing the second sealing material 303 between the chip tube 300 and the back substrate 202 by heat treatment. In addition, the front substrate 201 side is overlapped with the rear substrate 202 to which the chip tube 300 is attached, and the first sealing material 203 disposed between the substrates of the peripheral portion 120 is heat-treated, so that the peripheral portion of the panel is Sealed.

  FIG. 3B shows the shape of the tip tube 300. The tip tube 300 includes a trunk portion 301 which is a tube body having a predetermined diameter, a collar portion 302 which is a first end portion on the panel connection side, and a second end on the panel non-connection side (external pipe connection side). Part 308. The tip tube 300 is made of, for example, glass, ceramic, metal, or the like. The first end portion of the tip tube 300 has a collar portion 302 that extends outward from the trunk portion 301 so that the connection area with the back substrate 202 is increased in order to increase the strength of the connection with the back substrate 202 side. The connecting surface of the collar portion 302 to the back substrate 202 side (the overhang portion 204) is flat.

  In FIG. 3A, in the configuration of the first embodiment, the flange 302 which is the first end of the tip tube 300 is attached to the first surface (a) side of the hole 125 of the back substrate 202. Corresponding structure is provided with a counterbore part (concave part) 126 by counterbore processing. The counterbore part 126 has a diameter larger than the diameter of the hole 125 on the second surface (b) side, its bottom surface is parallel to the back substrate 202 surface, and its side surface is vertical. Corresponding to the counterbore part 126, the vicinity of the hole part 125 of the back substrate 202 is an overhang part (hook part) 204.

  Further, for example, the diameter (R1) of the counterbore portion 126 of the hole portion 125 is configured to be slightly larger than the diameter (R2) of the collar portion 302 of the tip tube 300. Further, the diameter (R3) of the hole portion 125 is configured to be slightly larger than the diameter (R4) of the trunk portion 301 of the tip tube 300.

  When the tip tube 300 is attached, the second sealing material 303 is disposed on the overhanging portion 204 corresponding to the bottom surface of the counterbore portion 126 in the back substrate 202, and on the first end portion of the tip tube 300. A certain collar portion 302 is placed so as to be caught. The trunk portion 301 and the second end portion 308 of the tip tube 300 pass through the hole 125 from the first surface (a) side and come out vertically to the second surface (b) side. For example, in the arrangement state of FIG. 3A, the flange portion 302 of the tip tube 300 has a shape that is hooked on the overhang portion 204, so that it does not fall out downward.

  Further, in the sealed state of the tip tube 300, the flange portion 302 with respect to the counterbore portion 126 has an upper surface facing the inside of the panel, for example, substantially the same height or lower than the first surface (a) of the back substrate 202. Configure to fit. For example, the thickness of the collar portion 302 is configured to be 1 mm or less.

<Manufacturing method>
Next, in FIG. 4 and FIG. 5, a manufacturing method of the PDP 10 according to the first embodiment, particularly a series of steps related to panel sealing will be described.

  First, in FIG. 4A, a back substrate 202 having a hole 125 with a counterbore 126 as shown in FIG. 3A is formed. The first sealing material 203 is disposed around the rear substrate 202, but this may be performed later.

  Next, in FIG. 4B, the second sealing material 303 is disposed on the overhanging portion 204, which is the bottom surface of the counterbore portion 126 of the hole portion 125 in the back substrate 202, by coating or molding. For the first sealing material 203 and the second sealing material 303, for example, a material mainly made of low-melting glass is used. As the second sealing material 303, for example, a member solidified by a preform according to the shape of the first end of the tip tube 300 may be used.

  Next, in FIG. 4C, the tip tube 300 is attached to the hole 125 in the back substrate 202. That is, the second end 308 and the backbone 301 of the tip tube 300 are inserted from the first surface (a) side of the hole 125, and the flange 302 serving as the first end is located on the overhanging portion 204. The second sealing material 303 is sandwiched between them.

  Next, in FIG. 4D, the tip tube 300 is sealed by the heat treatment of the second sealing material 303 in the hole 125 in the back substrate 202. That is, the second sealing material 303 is heated to its softening point (T2) or higher and melted, and then solidified by cooling. Here, a case is shown in which the upper surface of the collar portion 302 of the tip tube 300 fits below the first surface (a).

  Next, in FIG. 5E, the front substrate 201 with the first sealing material 203 sandwiched between the peripheral portion 120 and the rear substrate 202 to which the tip tube 300 is attached as shown in FIG. 4D. Align the sides and overlap.

  Next, in FIG. 5F, the peripheral portion of the panel is sealed by heat treatment of the first sealing material 203. That is, the first sealing material 203 is heated to its softening point (T1) or higher and melted, and then solidified by cooling. Thereby, the space 150 inside the panel is in a state of communicating with the outside only by the hole 125. Then, an external pipe is connected to the second end 308 of the tip tube 300. In this state, the space 150 inside the panel is evacuated and filled with a discharge gas. By disposing the tip tube 300 and the panel in the furnace, various heat treatments and exhaust / exhaust treatments are performed.

  Next, in FIG. 5G, the second end 308 of the tip tube 300 is turned into an end portion (closed portion) 309 that is sealed off and closed using a burner or the like. As a result, the space 150 inside the panel is finally completely hermetically sealed, and the assembly of the PDP 10 is completed.

  In the above configuration, the softening point (T2) of the second sealing material 303 for sealing the tip tube 300 is the softening point (T1) of the first sealing material 203 for sealing the periphery of the panel. It is desirable to make it higher (T2> T1). Since the second sealing material 303 is heat-treated and sealed earlier than the first sealing material 203, the temperature of the first sealing material 203 is higher than T1 and higher than T2 when the first sealing material 203 is heated later. Make it smaller.

  Further, in the above manufacturing method, the chip tube 300 is sealed as shown in FIG. 4D and then the peripheral portion of the panel is sealed as shown in FIG. 5F. A method of performing sealing of the peripheral portion in the same process is also possible. That is, both the first sealing material 203 and the second sealing material 303 including the first sealing material 203 and the second sealing material 303 are heat-treated at a time in a state where they are aligned and arranged to melt and fix both of them.

  As described above, according to the first embodiment, the first end of the tip tube 300 is fixed and sealed to the first surface (a) side on the inner side of the panel, for example, a panel in a manufacturing apparatus. The tip tube 300 does not drop off during movement or heat sealing, and a conventional fixing means such as a clip becomes unnecessary. Therefore, compared to the above-described prior art example, the manufacturing apparatus can have a simple structure, and the apparatus cost and the manufacturing cost can be reduced.

(Embodiment 2)
Next, a characteristic configuration of PDP 10 according to the second exemplary embodiment of the present invention will be described with reference to FIG. The basic configuration of the PDP 10 of the second embodiment is the same as that of the first embodiment, and the shapes of the hole 125 and the tip tube 300 are different.

  In the second embodiment, the hole 125 of the back substrate 202 is formed by machining as a tapered portion 127 that becomes a portion that hooks and holds the first end of the tip tube 300. The side surface of the hole portion 125 is configured as an inclined surface-shaped protruding portion 205 corresponding to the tapered portion 127. Correspondingly, the first end portion of the tip tube 300 has a shape having a flare portion 304 that is hooked to the protruding portion 205 of the hole portion 125. The flare portion 304 has a shape in which the diameter thereof is constantly increased as it reaches the end of the tip tube 300. The flare portion 304 has an angle of a certain degree or more with respect to the axial direction of the trunk portion 301 in order to be attached by catching. Between the surface of the overhanging portion 205 and the outer surface of the flare portion 304, the second sealing material 303 is disposed in a corresponding shape and fixed by heat treatment.

  In the first embodiment, a counterbore process is required for the back substrate 202, but in the second embodiment, a counterbore process is not required by using the tapered hole 125 and the tip tube 300 having a shape corresponding thereto. It was.

  The flare 304, which is the first end of the tip tube 300, is fixedly held with respect to the back substrate 202 by the shape of the tapered portion 127 and the flare 304, so that the tip tube 300 is fixed as in the first embodiment. Get the effect you can.

  In the third embodiment, the first end portion of the tip tube 300 is based on the shape of the flare portion 304 as in the second embodiment, and a part thereof (the butting portion 305) is a space 150 inside the panel. In this shape, it is fixed to and pressed against the inner surface of the front substrate 201.

  When the space 150 inside the panel is in a decompressed state and the second sealing material 303 is not fixed, a force drawn into the inside of the panel (upward in FIG. 7) acts on the tip tube 300. . In order to cope with this, it is conceivable to provide a function of fixing the tip tube 300 on the manufacturing apparatus side, but this is expensive. In this configuration, in order to cope with the above-described action, a part of the first end portion (the abutting portion 305) of the tip tube 300 is in contact with the inwardly facing surface of the front substrate 201 in advance.

  In the structure of the PDP 10, the softening points (T1, T2) of the first and second sealing materials (203, 303) are designed to be the same or T2 <T1. Alternatively, as a manufacturing method, the second in the vicinity of the tip tube 300 and the hole 125 is higher than the panel sealing temperature (t1), which is the temperature at which the first sealing material 203 is heated in the peripheral portion 120. The tip tube sealing temperature (t2), which is the ultimate maintenance temperature at the time of heating the sealing material 303, is set higher.

  According to the third embodiment, in addition to the same effects as those of the second embodiment, the front substrate 201 functions as a stopper for fixing and stopping the pull-in to the force pulled into the panel acting on the tip tube 300. Thus, the fixing performance of the tip tube 300 can be further improved.

(Embodiment 4)
Next, a characteristic configuration of PDP 10 according to the fourth exemplary embodiment of the present invention will be described with reference to FIG. The basic configuration of the PDP 10 of the fourth embodiment is the same as that of the first embodiment, the shape of the tip tube 300 is the same as that of the second embodiment, and the shapes of the holes 125 and the like are different.

  In the fourth embodiment, the hole portion 125 of the back substrate 202 is configured as a partially tapered portion 128 that is tapered only on the first surface (a) side and the second surface (b) side is perpendicular to the side surface. Yes. A side surface of the hole portion 125 of the back substrate 202 is configured as a partially inclined surface-shaped protruding portion 206 corresponding to the partially tapered portion 128. This portion is a portion that hooks and holds the first end portion (flared portion 304) of the tip tube 300 as in the second embodiment. A second sealing material 306 is disposed in a corresponding shape between a partially inclined surface of the overhang portion 206 and the outer surface of the flare portion 304, and is fixed by heat treatment.

  According to the fourth embodiment, the effect of fixing the tip tube 300 is obtained as in the second embodiment.

  The shape of the first end portion of the tip tube 300 is not limited to the collar portion 302 and the flare portion 304 but is fixed to the hole 125 of the rear substrate 202 by being caught on the first surface (a) side. Anything is valid.
