Description

  The present invention relates to a method for manufacturing a plasma display panel (hereinafter referred to as a panel).

  Panels used in this plasma display device are roughly classified into AC type and DC type in terms of driving, and there are two types of discharge types: surface discharge type and counter discharge type. Due to the simplicity of manufacturing, at present, the mainstream of plasma display devices is a surface discharge type having a three-electrode structure.

  In this surface discharge type plasma display panel structure, at least a pair of substrates whose front sides are transparent are arranged to face each other so that a discharge space is formed between the substrates, and partition walls for dividing the discharge space into a plurality of substrates are arranged on the substrate. In addition, an electrode group is arranged on the substrate so that a discharge is generated in the discharge space partitioned by the barrier ribs, and a discharge gas such as Xe or Ne is sealed in the discharge space to emit red, green, and blue light emitted by the discharge. A plurality of discharge cells are formed by providing phosphors that emit light, and the phosphors are excited by vacuum ultraviolet light having a short wavelength generated by discharge, and red, green, and blue are respectively emitted from red, green, and blue discharge cells. Color display is performed by emitting visible light.

  Such a plasma display device can display at a higher speed than a liquid crystal panel, has a wide viewing angle, is easy to enlarge, and is self-luminous so that the display quality is high. Recently, the flat panel display has attracted particular attention and is used for various purposes as a display device in a place where many people gather and a display device for enjoying a large screen image at home.

  By the way, in such a plasma display device, the discharge characteristics of the panel immediately after its manufacture are affected by the protective film formed in the panel and directly exposed to the discharge space, the impurities attached to the phosphor, etc. However, it cannot be realized with stable performance.

  Therefore, in general, after the panel is manufactured and before the plasma display device is assembled, a predetermined voltage is applied as shown in Patent Document 1 and Patent Document 2 to forcibly discharge for a predetermined time. A process is performed to stabilize the discharge characteristics.

Furthermore, in such a panel manufacturing process, after the panel is manufactured, the glass substrate constituting the front plate and the back plate cracks and breaks during the aging process for stabilizing the characteristics. As shown in Patent Document 3, a heat conducting member is brought into contact with the panel. A technique for performing an aging process while cooling is disclosed.

  By the way, in recent years, in such a plasma display device, the panel itself is increased in size so as to exceed 150 inches diagonally, or multiple chamfering such as cutting out 16 panels of 42 inches diagonally from one mother glass. Progressing.

  However, such a large glass substrate is likely to be warped during panel manufacture due to the influence of residual stress in the manufacturing process. Due to this warpage, when the aging process is performed, the heat conduction member that contacts the panel surface contacts only a part of the panel, and the distribution of heat generated by the aging is not within the panel surface. A phenomenon that becomes uniform occurs.

  The heat generated by aging has a great influence on the degassing action of impure gas or the like adsorbed on the protective film in the panel and the phosphor. For this reason, the heat distribution in the panel surface causes a difference in the in-plane discharge state, causing a problem that display defects such as color unevenness and luminance unevenness after the aging process occur.

  The present invention has an object to prevent display defects such as color unevenness and brightness unevenness of a panel in an aging process under such circumstances.

  In order to solve this problem, the plasma display panel manufacturing method of the present invention is configured such that a front substrate having a plurality of display electrode pairs and a rear substrate are arranged to face each other, and a predetermined voltage is applied to the display electrode pairs. In the method of manufacturing a plasma display panel having a step of performing aging, aging is performed in a state where a heat conductive member is bonded to the front substrate or the back substrate with an adhesive.

  Thereby, even if it is a panel which has curvature due to the residual stress produced in the glass substrate manufacturing process or the panel manufacturing process, aging can be performed with a uniform heat distribution in the panel surface.

  Here, the heat conductive member may be bonded by pressing with a roller in a state in which the warp of the plasma display panel is corrected to a flat surface. Thereby, aging can be performed in a state where the heat conducting member is effectively brought into close contact with the panel.

  The linear pressure of the pressure roller may be 1.0 kg / cm to 5.0 kg / cm. Thereby, aging can be performed in a state where the heat conductive member is in close contact with the panel without damaging the partition formed on the back plate.

  According to the method of manufacturing a plasma display panel according to the present invention, the uniformity of the in-plane distribution of the panel temperature during the aging process is improved, and the color unevenness and brightness due to the difference in the in-plane discharge state during the aging process. An effect of preventing the occurrence of display defects such as unevenness can be obtained.

  Hereinafter, although the manufacturing method of the plasma display panel by one Embodiment of this invention is demonstrated using FIGS. 1-6, the aspect of this invention is not limited to this.

  First, the structure of the panel in the plasma display device will be described with reference to FIG. As shown in FIG. 1, the panel is configured by disposing a glass front substrate 1 and a back substrate 2 so as to form a discharge space therebetween. On the front substrate 1, a plurality of scanning electrodes 3 and sustaining electrodes 4 constituting display electrodes are formed in parallel with each other. A dielectric layer 5 is formed so as to cover the scan electrode 3 and the sustain electrode 4, and a protective layer 6 is formed on the dielectric layer 5.

  A plurality of data electrodes 8 covered with an insulator layer 7 are provided on the back substrate 2, and a grid-like partition wall 9 is provided on the insulator layer 7. A phosphor layer 10 is provided on the surface of the insulator layer 7 and on the side surfaces of the partition walls 9. The front substrate 1 and the rear substrate 2 are arranged to face each other so that the scan electrodes 3 and the sustain electrodes 4 and the data electrodes 8 cross each other, and in the discharge space formed between them, for example, neon And a mixed gas of xenon. Note that the structure of the panel is not limited to the above-described structure, and for example, a structure having a stripe-shaped partition may be used.

  FIG. 2 is an electrode array diagram of this panel. N scan electrodes SC1 to SCn (scan electrode 3 in FIG. 1) and n sustain electrodes SU1 to SUn (sustain electrode 4 in FIG. 1) are arranged in the row direction, and m data electrodes D1 to D1 are arranged in the column direction. Dm (data electrode 8 in FIG. 1) is arranged. A discharge cell is formed at a portion where a pair of scan electrode SCi and sustain electrode SUi (i = 1 to n) and one data electrode Dj (j = 1 to m) intersect, and the discharge cell is in the discharge space. M × n are formed.

  FIG. 3 is a circuit block diagram of a plasma display device using this panel. The plasma display device includes a panel 11, an image signal processing circuit 12, a data electrode drive circuit 13, a scan electrode drive circuit 14, a sustain electrode drive circuit 15, a timing generation circuit 16, and a power supply circuit (not shown).

  The image signal processing circuit 12 converts the image signal sig into image data for each subfield. The data electrode drive circuit 13 converts the image data for each subfield into signals corresponding to the data electrodes D1 to Dm, and drives the data electrodes D1 to Dm. The timing generation circuit 16 generates various timing signals based on the horizontal synchronization signal H and the vertical synchronization signal V, and supplies them to each drive circuit block. Scan electrode drive circuit 14 supplies drive voltage waveforms to scan electrodes SC1 to SCn based on timing signals, and sustain electrode drive circuit 15 supplies drive voltage waveforms to sustain electrodes SU1 to SUn based on timing signals. Here, the scan electrode drive circuit 14 and the sustain electrode drive circuit 15 include a sustain pulse generator 17.

  Next, a driving voltage waveform for driving the panel and its operation will be described with reference to FIG. FIG. 4 is a diagram showing drive voltage waveforms applied to the respective electrodes of the panel.

  In the plasma display device according to the present embodiment, one field is divided into a plurality of subfields, and each subfield has an initialization period, an address period, and a sustain period.

  In the initializing period of the first subfield, the data electrodes D1 to Dm and the sustain electrodes SU1 to SUn are held at 0 (V), and from the voltage Vi1 (V) that is lower than the discharge start voltage with respect to the scan electrodes SC1 to SCn. A ramp voltage that gradually increases toward the voltage Vi2 (V) exceeding the discharge start voltage is applied. Then, the first weak initializing discharge is caused in all the discharge cells, negative wall voltages are stored on scan electrodes SC1 to SCn, and positive walls on sustain electrodes SU1 to SUn and data electrodes D1 to Dm. The voltage is stored. Here, the wall voltage on the electrode refers to a voltage generated by wall charges accumulated on the dielectric layer or the phosphor layer covering the electrode.

  Thereafter, sustain electrodes SU1 to SUn are maintained at positive voltage Vh (V), and a ramp voltage that gradually decreases from voltage Vi3 (V) to voltage Vi4 (V) is applied to scan electrodes SC1 to SCn. Then, the second weak initializing discharge is caused in all the discharge cells, the wall voltage between scan electrodes SC1 to SCn and sustain electrodes SU1 to SUn is weakened, and the wall voltage on data electrodes D1 to Dm is reduced. Is also adjusted to a value suitable for the write operation.

  In the subsequent address period, scan electrodes SC1 to SCn are temporarily held at Vr (V). Next, negative scan pulse voltage Va (V) is applied to scan electrode SC1 in the first row, and data electrode Dk (k = 1 to 1) of the discharge cell to be displayed in the first row among data electrodes D1 to Dm. A positive write pulse voltage Vd (V) is applied to m). At this time, the voltage at the intersection between the data electrode Dk and the scan electrode SC1 is obtained by adding the wall voltage on the data electrode Dk and the wall voltage on the scan electrode SC1 to the externally applied voltage (Vd−Va) (V). And the discharge start voltage is exceeded. Then, an address discharge occurs between data electrode Dk and scan electrode SC1 and between sustain electrode SU1 and scan electrode SC1, and a positive wall voltage is accumulated on scan electrode SC1 of this discharge cell, and on sustain electrode SU1. And a negative wall voltage is also accumulated on the data electrode Dk.

  In this manner, an address operation is performed in which address discharge is caused in the discharge cells to be displayed in the first row and wall voltage is accumulated on each electrode. On the other hand, the voltage at the intersection of the data electrodes D1 to Dm and the scan electrode SC1 to which the address pulse voltage Vd (V) is not applied does not exceed the discharge start voltage, so that address discharge does not occur. The above address operation is sequentially performed until the discharge cell in the nth row, and the address period ends.

  In the subsequent sustain period, positive sustain pulse voltage Vs (V) is applied to scan electrodes SC1 to SCn as a first voltage, and ground potential, that is, 0 (V) is applied to sustain electrodes SU1 to SUn as a second voltage. Apply. In the discharge cell in which the address discharge has occurred at this time, the voltage between scan electrode SCi and sustain electrode SUi is the sustain pulse voltage Vs (V), the wall voltage on scan electrode SCi and the wall voltage on sustain electrode SUi. Is added and exceeds the discharge start voltage. Then, a sustain discharge occurs between scan electrode SCi and sustain electrode SUi, and the phosphor layer emits light due to the ultraviolet rays generated at this time. Then, a negative wall voltage is accumulated on scan electrode SCi, and a positive wall voltage is accumulated on sustain electrode SUi. At this time, a positive wall voltage is also accumulated on the data electrode Dk.

  In the discharge cells in which no address discharge has occurred in the address period, no sustain discharge occurs, and the wall voltage at the end of the initialization period is maintained. Subsequently, 0 (V) that is the second voltage is applied to scan electrodes SC1 to SCn, and sustain pulse voltage Vs (V) that is the first voltage is applied to sustain electrodes SU1 to SUn. Then, in the discharge cell in which the sustain discharge has occurred, the voltage between the sustain electrode SUi and the scan electrode SCi exceeds the discharge start voltage, so that the sustain discharge occurs again between the sustain electrode SUi and the scan electrode SCi, Negative wall voltage is accumulated on sustain electrode SUi, and positive wall voltage is accumulated on scan electrode SCi.

  Thereafter, similarly, by applying sustain pulses of the number corresponding to the luminance weight alternately to scan electrodes SC1 to SCn and sustain electrodes SU1 to SUn, the sustain discharge continues in the discharge cells that have caused the address discharge in the address period. Done. Thus, the maintenance operation in the maintenance period is completed.

  The operations in the initialization period, address period, and sustain period in the subsequent subfield are substantially the same as those in the first subfield, and thus description thereof is omitted.

  Next, a method for manufacturing a panel will be described. First, the scan electrode 3 and the sustain electrode 4 are formed on the front substrate 1. These are composed of a transparent electrode, a metal bus electrode, and a black electrode, and each is formed by patterning using a photolithography method or the like. The transparent electrode is formed by using a thin film process or the like, and the metal bus electrode is solidified by baking a paste containing a silver material at a desired temperature. In the same step, the black electrode is formed by screen printing a paste containing a black pigment or by forming a black pigment on the entire surface of the glass substrate and then patterning and baking using a photolithography method.

  Next, a dielectric paste is applied on the front substrate 1 by a die coating method so as to cover the scan electrodes 3 and the sustain electrodes 4 to form a dielectric paste layer (dielectric material layer). After the dielectric paste is applied, the surface of the applied dielectric paste is leveled by leaving it to stand for a predetermined time, so that a flat surface is obtained. Then, the dielectric layer 5 is formed by baking and solidifying the dielectric paste layer. The dielectric paste is a paint containing a dielectric material such as glass powder, a binder and a solvent. Next, a protective layer 6 made of magnesium oxide (MgO) is formed on the dielectric layer 5 by vacuum deposition. Through the above steps, predetermined components are formed on the front substrate 1 to complete the front plate.

  On the other hand, the back plate is formed as follows. First, the composition for the data electrode 8 is formed by a method of screen printing a paste containing a silver (Ag) material on the back substrate 2 or a method of forming a metal film on the entire surface and then patterning using a photolithography method. A data layer is formed, and the data electrode 8 is formed by firing the material layer at a desired temperature. Next, a dielectric paste is applied on the rear glass substrate on which the data electrodes 8 are formed by a die coating method or the like so as to cover the data electrodes 8 to form a dielectric paste layer. Thereafter, the dielectric paste layer is fired to form the insulator layer 7. The dielectric paste is a paint containing a dielectric material such as glass powder, a binder and a solvent.

  Next, a partition wall forming paste containing a partition wall material is applied on the insulator layer 7 by a screen printing method, a die coating method, or the like, and patterned into a predetermined shape to form a partition wall material layer, and then fired. A partition wall 9 is formed. Here, as a method of patterning the partition wall paste applied on the insulator layer 7, a photolithography method or a sand blast method can be used. Next, the phosphor layer 10 is formed by applying and baking a phosphor paste containing a phosphor material on the insulator layer 7 between the adjacent barrier ribs 9 and on the side surfaces of the barrier ribs 9. Through the above steps, a back plate having predetermined components on the back substrate 2 is completed.

  In this way, the front plate and the back plate provided with the predetermined constituent members are accurately opposed to each other so that the scanning electrode 3 and the data electrode 8 are orthogonal to each other, and the periphery thereof is sealed with a glass frit, and the discharge space. A panel is completed by enclosing a discharge gas containing Ne, Xe or the like.

  Thereafter, for the purpose of stabilizing the discharge voltage, aging is performed by applying a predetermined voltage to scan electrode 3 and sustain electrode 4.

  Next, the aging process according to this embodiment will be described in detail. 6 (a) and 6 (b) show a state in which an aging process is performed in the method of manufacturing a plasma display panel according to the first embodiment of the present invention. FIG. 6 (a) is a sectional view, and FIG. b) is a top view.

  The panel 101 manufactured by the above manufacturing method is placed on the aging unit table 104, and an aging process is performed in which display driving is performed by applying a driving waveform with a predetermined frequency and a predetermined voltage to the scanning electrodes and sustaining electrodes of the panel.

  In this aging process, the panel 101 is disposed on the aging unit table 104 with the back plate side facing down. A scanning electrode driving unit (not shown), a sustain electrode driving unit (not shown), and an address electrode driving unit (not shown) are connected to terminals drawn out at both ends of the panel, and predetermined electrodes are connected to the respective electrodes. Apply voltage.

  At this time, a drive voltage having an aging voltage waveform that periodically changes with a predetermined waveform is applied to each scan electrode from the scan electrode driving unit. Further, a similar drive voltage whose phase is shifted from the drive voltage applied to the scan electrode by a half cycle is applied to each sustain electrode from the sustain electrode driver.

  In the present invention, a voltage of 200 V is generated from the DC power source 105, and a voltage waveform ringed by the LC resonance circuit 106 is applied at a frequency of 45 kHz as an aging voltage waveform including an alternating voltage component. A rectangular pulse may be applied for the purpose of adapting to the panel characteristics.

  A waveform was not applied to the address electrode terminals formed on the back plate, and the potential was set to the GND potential. In the case of performing counter discharge, a predetermined voltage may be applied to the address electrode terminal at a predetermined frequency.

  Next, after confirming that the scanning electrode terminal and the sustain electrode terminal are in complete contact with the electrode and there is no display defect area due to poor contact, the waveform application is temporarily stopped and the panel 101 is adsorbed to the aging unit base 104 (adsorption) A mechanism is not shown), and a heat conductive sheet 102 having a thickness of 0.5 mm on the front plate surface side and a thickness of 10 μm on the side in contact with the panel is disposed on the panel 101.

  Next, as shown in FIG. 6 (a), a heat conductive sheet 102 disposed on the panel front plate with a pressure roller 103 is applied over the entire surface at a roller linear pressure of 1.0 kg / cm to 5.0 kg / cm. The heat conductive sheet 102 on the front plate side is bonded to and adhered to the panel 101. After bonding, it is possible to prevent cracking due to deformation of the glass substrate due to heat generation from the panel 101 during the aging process when the panel is released from adsorption.

  In this manner, the waveform is continuously applied until the aging process is completed in a state where the heat conductive sheet 102 is in close contact with the panel front plate.

  With this configuration, the heat generated by the discharge of the panel 101 during the aging process is uniformly released into the space through the heat conductive sheet 102 on the front plate side. In this way, the panel 101 is uniformly cooled in the plane. Further, when a metal cooling fin or the like is brought into close contact with the heat conductive sheet 102, the heat dissipation effect is improved. In addition, it is desirable from the viewpoint of physical distribution that the heat conductive sheet 102 is peeled off before the panel 101 is transferred to the next process.

  As described in the above embodiment, in the present invention, the plasma display panel in which different warpages are generated at the time of aging is installed in an aging unit having means for uniformly cooling the surface, and the in-plane of the panel Since the aging process is performed while maintaining a uniform temperature distribution, it is possible to prevent the occurrence of display defects such as color unevenness and brightness unevenness due to differences in the in-plane discharge state during the aging process. It is done.

  In the embodiment of the present invention, the heat conductive sheet is bonded only to the front plate side. However, the heat conductive sheet is installed on the front plate side aging stand side, the heat conductive sheet is arranged on the back plate side, and pressure is applied. By sticking a heat conductive sheet to both sides on the side and the back plate side, the purpose of improving the uniformity of the in-plane temperature distribution can be achieved, and the same effect can be obtained.

  Moreover, in this invention, although the heat conductive sheet is bonded by the linear pressure of a pressure roller 1.0kg / cm-5.0kg / cm, the linear pressure to press is optimal from the difference of the elasticity of a heat conductive sheet, etc. It can also be changed to a value.

  As described above, according to the plasma display panel manufacturing method of the present invention, the uniformity of the in-plane temperature distribution during the aging process is improved, and the occurrence of display defects such as color unevenness and brightness unevenness is suppressed. The manufacturing yield of the plasma display panel can be improved.
