Hereinafter, the front electrodes 202 and 203 are divided into the scan electrode 202 and the sustain electrode 203, and the rear electrode 213 is called an address electrode 213.

The front substrate 201 having the scan electrode 202 and the sustain electrode 203 limits the discharge current of the scan electrode 202 and the sustain electrode 203, and insulates the scan electrode 202 and the sustain electrode 203 from each other. Top dielectric layer 204 may be disposed.

A protective layer 205 may be formed on the front substrate 201 where the upper dielectric layer 204 is formed to facilitate discharge conditions. The protective layer 205 may include a material having a high secondary electron emission coefficient, such as magnesium oxide (MgO) material.

On top of the lower dielectric layer 215, a partition space 212, such as a stripe type, a well type, a delta type, a honeycomb type, etc., is formed on the discharge space, that is, to partition the discharge cells. Can be. Accordingly, the first discharge cell emitting red (R) light, the second discharge cell emitting blue (B) light, and the green (Green) light between the front substrate 201 and the rear substrate 211. : G) A third discharge cell or the like that emits light can be formed.

Referring to FIG. 3, a frame for implementing gray levels of an image may include a plurality of subfields SF1 to SF8.

In addition, the plurality of subfields may include a sustain period for implementing gradation according to an address period and a number of discharges for selecting discharge cells in which discharge cells will not occur or discharge cells in which discharge occurs. Period) may be included.

For example, in case of displaying an image with 256 gray levels, for example, one frame is divided into eight subfields SF1 to SF8 as shown in FIG. 3, and each of the eight subfields SF1 to SF8 is an address. It can include a period and a sustain period.

Alternatively, at least one subfield of the plurality of subfields of the frame may further include a reset period for initialization.

In addition, at least one subfield of the plurality of subfields of the frame may not include a sustain period.

Meanwhile, the weight of the corresponding subfield may be set by adjusting the number of sustain signals supplied in the sustain period. That is, a predetermined weight can be given to each subfield using the sustain period. For example, the weight of each subfield is 2 ⁿ by setting the weight of the first subfield to 2 ⁰ and the weight of the second subfield to 2 ¹ (where n = 0, 1, 2, 3, 4, 5, 6, 7) can be set to increase the ratio. As described above, gray levels of various images may be realized by adjusting the number of sustain signals supplied in the sustain period of each subfield according to the weight in each subfield.

In FIG. 3, only one image frame is composed of eight subfields. However, the number of subfields constituting one image frame may be variously changed. For example, one video frame may be configured with 12 subfields from the first subfield to the twelfth subfield, or one video frame may be configured with 10 subfields.

In addition, in FIG. 3, subfields are arranged in an order of increasing weight in one image frame. Alternatively, subfields may be arranged in an order of decreasing weight in one image frame. Subfields may be arranged regardless.

At least one of the plurality of subfields included in the frame may be a selective erase subfield (SE), and at least one of the plurality of subfields may be a selective write subfield (SW). Do.

If one frame includes at least one selective erase subfield and an optional write subfield, the first subfield or the first and second subfields of the plurality of subfields of the frame are the selective write subfields, It may be desirable for the remainder to be selective erasure subfields.

The selective erasure subfield may include an address period for selecting a discharge cell to be turned off and a sustain period for generating sustain discharge in discharge cells not selected in the address period.

The selective write subfield is a subfield that turns on the discharge cells supplied with the data signal Data to the address electrodes in the address period in the sustain period after the address period.

The selective write subfield may include a reset period for initializing the discharge cells, an address period for selecting the discharge cells to be turned on, and a sustain period for generating sustain discharge in the discharge cells selected in the address period.

4 is a diagram schematically illustrating a method of driving a plasma display panel. The driving waveform to be described below is supplied by the driving unit 110 of FIG. 1.

Referring to FIG. 4, in the reset period RP for initializing at least one subfield among a plurality of subfields of a frame, the reset signal RS is applied to the scan electrode Y. Can supply Here, the reset signal RS may include a rising ramp signal (Ramp-Up: RU) in which the voltage gradually rises and a falling ramp signal (Ramp-Down: RD) in which the voltage gradually falls.

For example, the rising ramp signal RU may be supplied to the scan electrode in the setup period SU of the reset period, and the falling ramp signal RD may be supplied to the scan electrode in the setdown period SD after the setup period. .

When the rising ramp signal is supplied to the scan electrode, a weak dark discharge, that is, setup discharge, occurs in the discharge cell by the rising ramp signal. By this setup discharge, the distribution of wall charges can be uniform in the discharge cells.

After the rising ramp signal is supplied, when the falling ramp signal is supplied to the scan electrode, a weak erase discharge, that is, a setdown discharge, occurs in the discharge cell. By this set-down discharge, wall charges such that address discharge can be stably generated can be uniformly retained in the discharge cells.

In the address period AP after the reset period, the scan reference signal Ybias having a voltage higher than the lowest voltage of the falling ramp signal may be supplied to the scan electrode.

In addition, in the address period, the scan signal Sc that falls from the voltage of the scan reference signal Ybias may be supplied to the scan electrode.

Meanwhile, the pulse width of the scan signal supplied to the scan electrode in the address period of at least one subfield may be different from the pulse width of the scan signal of another subfield. For example, the width of the scan signal in the subfield located later in time may be smaller than the width of the scan signal in the preceding subfield. In addition, the reduction of the scan signal width according to the arrangement order of the subfields can be made gradually, such as 2.6 Hz (microseconds), 2.3 Hz, 2.1 Hz, 1.9 Hz, or 2.6 Hz, 2.3 Hz, 2.3 Hz, 2.1 Hz. .... 1.9 ㎲, 1.9 ㎲ and so on.

As such, when the scan signal is supplied to the scan electrode, the data signal Dt may be supplied to the address electrode X corresponding to the scan signal.

When the scan signal and the data signal are supplied, an address discharge may be generated in the discharge cell to which the data signal is supplied while the voltage difference between the scan signal and the data signal and the wall voltage generated by the wall charges generated in the reset period are added. .

In addition, the sustain reference signal Zbias signal may be supplied to the sustain electrode in the address period in which the address discharge occurs so that the address discharge is effectively generated between the scan electrode and the address electrode.

In the sustain period SP after the address period, the sustain signal SUS may be supplied to at least one of the scan electrode and the sustain electrode. For example, a sustain signal may be alternately supplied to the scan electrode and the sustain electrode.

When such a sustain signal is supplied, the discharge cell selected by the address discharge is added with the wall voltage in the discharge cell and the sustain voltage Vs of the sustain signal, and a sustain discharge, i.e., display between the scan electrode and the sustain electrode when the sustain signal is supplied. Discharge may occur.

In this way, an image can be realized.

First, referring to FIG. 9, at least one address electrode X overlapping the exhaust hole 240 in the longitudinal direction LD of the address electrode X is divided into a plurality of address electrodes X. Can be.

For example, the first and second long sides LS1 and the second long side LS2 of the rear substrate 211 are formed on the rear substrate 211 among the first to ten address electrodes X1 to X10. The first address electrode X1 overlapping the exhaust hole 240 may be divided into a first sub address electrode 910 and a second sub address electrode 902. Here, the first sub address electrode 901 and the second sub address electrode 902 may be divided based on the exhaust hole 240. On the other hand, the second to ten address electrodes X2 to X10 may not be divided.

In this case, the undivided address electrode, for example, the second address electrode X2, is electrically connected to the second connection substrate 702 disposed on the first long side LS1 side of the rear substrate 211. The data signal may be supplied from the connection substrate 702.

On the other hand, the first address electrode X1, which is overlapped with the exhaust hole 240, is electrically connected to the first connection substrate 701 which is different from the second connection substrate 702. The first sub-address electrode 901 of (X1) is electrically connected to the first sub-connecting substrate 701A disposed at the first long side LS1 of the rear substrate 211 of the first connecting substrate 701, The second sub-address electrode 902 of the first address electrode X1 is electrically connected to the second sub-connecting substrate 701B disposed on the second long side LS2 of the rear substrate 211 of the first connecting substrate 701.

In addition, each of the first sub-address electrode 901 and the second sub-address electrode 902 may overlap at least one discharge cell.

For example, as in the case of FIG. 11, a discharge cell disposed at a portion where the first scan electrode Y1 and the first sustain electrode Z1 intersect is called a first discharge cell ① and the second scan electrode. A discharge cell disposed at a portion where Y2 and the second sustain electrode Z2 intersect is called a second discharge cell ②, and a portion where the third scan electrode Y3 and the third sustain electrode Z3 cross each other. The discharge cells arranged in the third discharge cell ③ are referred to as third discharge cells ③, and the discharge cells arranged at the intersections of the fourth scan electrode Y4 and the fourth sustain electrode Z4 are referred to as fourth discharge cells ④. The discharge cell disposed at a portion where the fifth scan electrode Y5 and the fifth sustain electrode Z5 intersect is called a fifth discharge cell ⑤, and the sixth scan electrode Y6 and the sixth sustain electrode Z6 Assume that the discharge cells arranged at the intersections of?) Are the sixth discharge cells (?).

In this case, the second address electrode X2 may be commonly overlapped with the first to sixth discharge cells ①②③④⑤⑥ corresponding to the second address electrode X2. That is, the second address electrode X2 can supply a data signal to the first to sixth discharge cells ①②③④⑤⑥. In addition, the data signal supplied to the first to sixth discharge cells ①②③④⑤⑥ may be supplied from the second connection substrate 702.

On the other hand, the first sub-address electrode 901 of the first address electrode X1 overlaps the first to third address electrodes ①②③ corresponding to the first address electrode X1 and the first address electrode X1.

The data signal can be supplied to the cell (④⑤⑥). In addition, the data signal supplied to the first to third discharge cells ①②③ may be supplied from the first sub-connecting substrate 701A of the first connecting substrate 701 and supplied to the fourth to sixth discharge cells ④⑤⑥. The data signal may be supplied from the second sub-connecting substrate 701B of the first connecting substrate 701.

In detail, as in the case of FIG. 12, when it is assumed that the scan signals Sc are sequentially supplied to the first to sixth scan electrodes Y1 to Y6, the second connection substrate 702 discharges the first to sixth discharges. The data signal may be supplied to the cells ①②③④⑤⑥ in order to correspond to the scan signal Sc in sequence. In addition, the first sub-connecting substrate 701A of the first connecting substrate 701 supplies the data signal to the first sub-address electrode 901 of the first address electrode X1 sequentially corresponding to the scan signal Sc. In addition, the second sub-connecting substrate 701B of the first connecting substrate 701 may supply the data signal to the second sub-address electrode 902 in order to correspond to the scan signal Sc.

In this case, a portion that is hard to generate a discharge and is seen as a defect on the screen may be an A1 region as in the case of FIGS. 10 to 11.

Meanwhile, unlike the present invention, when the address electrode X overlapping the exhaust hole 240 is not divided, as shown in FIG. 13, the connection boards 701 and 702 are formed on one side of the rear substrate 211. Can be placed on. For example, the first substrate 701 and the second substrate 702 may be disposed on the first long side LS1 of the rear substrate 211, and a data signal may be supplied to each address electrode X. FIG. have.

More specifically, as in the case of FIG. 14, even when the first address electrode X1 overlaps the exhaust hole 240, the first connecting substrate 701 is connected to one side of the first address electrode X1 and is formed. The data signal can be supplied to the one address electrode X1.

In this case, the data signal may not be supplied to a portion of the first address electrode X1 disposed on the opposite side of the first connection substrate 701 based on the exhaust hole 240. This is because part of the first address electrode X1 may be removed in the process of forming the exhaust hole 240.

As a result, a defect in which an image is not displayed may occur in the area A2 of FIGS. 13 to 14.

Previously, when comparing the size of the area A1 of FIGS. 10 to 11 and the area A2 of FIGS. 13 to 14 (that is, comparing the size of defects), the size of the area A1 of FIGS. It can be seen that is smaller than the size of the A2 region of FIGS. 13 to 14. That is, the present invention can reduce the size of screen defects in which an image is not displayed.

Meanwhile, the lengths of the address electrodes divided by the exhaust holes 200 and the non-divided address electrodes are compared as follows.

Referring to FIG. 15, the total length L1 + L2 of the first address electrode X1 divided by the exhaust hole 240 may be different from the length L4 of the second address electrode X2 that is not divided.

Alternatively, the length L1 of the first sub-address electrode 901 of the first address electrode X1 and the length L2 of the second sub-address electrode 902 may be the length L4 of the second address electrode X2. Can be less than

In addition, the length L1 of the first sub-address electrode 901 and the length L2 of the second sub-address electrode 902 may vary according to the position of the exhaust hole 240. For example, the first sub address electrode 901 is disposed between the first long side LS1 of the rear substrate 211 and the exhaust hole 240, and the second sub address electrode 902 is the rear substrate 211. When disposed between the second long side LS2 of the second side and the exhaust hole 240, the gap D1 between the exhaust hole 240 and the first long side LS1 of the rear substrate 211 is defined as the exhaust hole ( The length L10 of the first sub-address electrode 901 and the length of the second sub-address electrode 902 (if different from the distance D2 between the 240 and the second long side LS2 of the rear substrate 211). L2) may be different.

Preferably, the distance D1 between the exhaust hole 240 and the first long side LS1 of the rear substrate 211 is a distance between the exhaust hole 240 and the second long side LS2 of the rear substrate 211. In the case of larger than D2, the length L1 of the first sub address electrode 901 may be longer than the length L2 of the second sub address electrode 902.

In addition, one of the first sub-address electrode 901 and the second sub-address electrode 902 of the first address electrode X1 may extend further than the second address electrode X2. For example, as shown in FIG. 16, the first sub-address electrode 901 and the second address electrode X2 of the first address electrode X1 are disposed on the first long side LS1 side of the rear substrate 211. Respectively, the second sub-address electrode 902 of the first address electrode X1 is connected to the first sub-connecting substrate 701A or the second connecting substrate 702 and the second long side LS2 of the rear substrate 211. When the second sub-connecting substrate 701B is connected to the second sub-connecting substrate 701B, the second sub-address electrode 902 is further extended by S1 toward the second long side LS2 of the rear substrate 211 compared to the second address electrode X2. Can be extended.

Here, the length S1 of the portion where the second sub-address electrode 902 extends relative to the second address electrode X2 is the first sub-address electrode 901 and the second sub as in the case of FIG. 15. When the length L1 of the first sub-address electrode 901 and the length L1 of the second sub-address electrode L2 are smaller than the distance L3 between the address electrodes 902, the second address electrode It may be smaller than the length of (L4).

On the other hand, the length S1 of the portion in which the second sub-address electrode 902 extends relative to the second address electrode X2 is equal to the distance between the first sub-address electrode 901 and the second sub-address electrode 902. When larger than L3, the sum L1 + L2 of the length L1 of the first sub-address electrode 901 and the length of the second sub-address electrode L2 may be greater than the length of the second address electrode L4. have.

Meanwhile, as in the case of FIG. 17, the exhaust hole 240 is formed in an active area (AA) in which an image is displayed by forming discharge cells partitioned by the partition wall 212, and the exhaust hole 240 is formed in the exhaust hole 240. It is possible to overlap with at least two discharge cells in the length direction of the address electrode X. As such, when the exhaust hole 240 is formed in the effective area AA, the size of the bezel area BA in which an image is not displayed may be reduced.

In this case, the first sub-address electrode 901 is disposed in one of the two discharge cells overlapping the exhaust hole 240 in the longitudinal direction of the address electrode X, and the second sub-address electrode 902 in the other one. ) May be arranged.

For example, as shown in FIG. 18, when the first discharge cell 1800 and the second discharge cell 1810 disposed adjacent to each other in the longitudinal direction of the address electrode X overlap the exhaust hole 240. The first sub-address electrode 901 may be disposed in the first discharge cell 1800, and the second sub-address electrode 902 may be disposed in the second discharge cell 1810.

In addition, the size of the portions AR1 and AR2 overlapping the exhaust hole 240 in each of the first discharge cell 1800 and the second discharge cell 1810 is the first discharge cell 1800 and the second discharge cell ( It may be desirable to be less than half the total size of 1810). For example, when the length of the first discharge cell 1800 in the longitudinal direction of the address electrode X is B, the area AR1 where the first discharge cell 1800 and the exhaust hole 240 overlap is defined as It may be desirable not to exceed half of the length of one discharge cell 1800, that is, the B / 2 point. In addition, when the length of the second discharge cell 1810 in the longitudinal direction of the address electrode X is B1, the area AR2 where the second discharge cell 1810 and the exhaust hole 240 overlap is a second discharge. It may be desirable not to exceed half the length of the cell 1810, ie, the B1 / 2 point.

In this case, an image may be displayed by discharge occurring in the first and second discharge cells 1800 and 1810. Accordingly, the size of the screen defect can be further reduced.

In addition, as shown in FIG. 19, the exhaust hole 240 may overlap the first, second, third, and fourth discharge cells 1900, 1910, 1920, and 1930 of the plurality of discharge cells. Here, the first discharge cell 1900 and the second discharge cell 1910 are disposed adjacent to each other in the longitudinal direction LD of the address electrode X, and the third discharge cell 1920 and the fourth discharge cell 1930 are disposed. In addition, the address electrodes X may be disposed adjacent to each other in the longitudinal direction.

In addition, the first discharge cell 1900 and the third discharge cell 1920 are disposed adjacent to each other in the width direction WD of the address electrode X, and the second discharge cell 1910 and the fourth discharge cell 1930 are disposed. In addition, the address electrodes X may be disposed adjacent to each other in the width direction WD.

In this case, the sub-discharge electrodes 901a and 902a divided by the exhaust holes 240 are disposed in the first discharge cell 1900 and the second discharge cell 1910, and the third discharge cell 1920 and the fourth discharge cell 1910 are disposed. Sub-address electrodes 901b and 902b divided by the exhaust hole 240 may be disposed in the discharge cell 1930. That is, a plurality of address electrodes Xa and Xb are divided by the exhaust holes 240.

In the case of FIG. 19, since one exhaust hole 240 overlaps with four discharge cells 1900 to 1930, even if the size of the exhaust hole 240 is increased, an excessive increase in the size of the screen defect can be suppressed. Alternatively, the size of the areas AR10 to AR13 overlapping the exhaust hole 240 in the first, second, third, and fourth discharge cells 1900 to 1930 may be reduced, thereby reducing the size of screen defects.

In addition, as in the case of FIG. 20, the exhaust hole 240 may overlap the first, second, third, fourth, fifth, and sixth discharge cells 2000 to 2050 of the plurality of discharge cells. Here, the first discharge cell 2000 and the second discharge cell 2010, the third discharge cell 2020 and the fourth discharge cell 2030, the fifth discharge cell 2040 and the sixth discharge cell 2050 Each of the address electrodes X may be disposed adjacent to each other in the longitudinal direction LD.

In addition, the first discharge cell 2000, the third discharge cell 2020, and the fifth discharge cell 2040 are disposed adjacent to each other in the width direction WD of the address electrode X, and the second discharge cell 2010 is disposed. The fourth discharge cell 2030 and the sixth discharge cell 2050 may also be disposed adjacent to each other in the width direction WD of the address electrode X.

In this case, sub-address electrodes 901a1 and 902a1 divided by the exhaust holes 240 are disposed in the first discharge cell 2000 and the second discharge cell 2010, and the third discharge cell 2020 and the fourth discharge cell 2000 are disposed. The sub-address electrodes 901b1 and 902b1 divided by the exhaust holes 240 are disposed in the discharge cells 2030, and the exhaust holes 240 are disposed in the fifth and sixth discharge cells 2040 and 2050. The divided sub-address electrodes 901c1 and 902c1 may be disposed.

20, even if one exhaust hole 240 overlaps the plurality of discharge cells 2000 to 2050, even if the size of the exhaust hole 240 is increased, an excessive increase in the size of the screen defect can be suppressed. Alternatively, the size of the areas AR20 to AR25 overlapping the exhaust hole 240 in each discharge cell 2000 to 2050 may be reduced, thereby reducing the size of screen defects.

In addition, in the case of FIG. 20, the size of the regions AR22 and AR23 in which the third discharge cell 2020 and the fourth discharge cell 2030 overlap the exhaust hole 240 may be the size of the first discharge cell 2000, The second discharge cell 2010, the fifth discharge cell 2040, and the sixth discharge cell 2050 may be larger than the size of the areas AR20, AR21, AR24, and AR25 overlapping the exhaust hole 240.

In this case, the sub-address electrode 901a1 disposed in the first discharge cell 2000 and the sub-address electrode 901c1 disposed in the fifth discharge cell 2040 are the sub-address disposed in the third discharge cell 2020. The electrode may be extended by a predetermined length S10 or S11 than the electrode 901b1. In this case, the total length of the sub address electrode 901a1 disposed in the first discharge cell 2000 and the sub address electrode 901c1 disposed in the fifth discharge cell 2040 is disposed in the third discharge cell 2020. It may be longer than the total length of the sub-address electrode 901b1.

In addition, the sub-address electrode 902a1 disposed in the second discharge cell 2010 and the sub-address electrode 902c1 disposed in the sixth discharge cell 2050 have a sub-address electrode disposed in the fourth discharge cell 2030 ( It may extend by a predetermined length (S12, S13) than 902b1). In this case, the total length of the sub address electrode 902a1 disposed in the second discharge cell 2010 and the sub address electrode 902c1 disposed in the sixth discharge cell 2050 is disposed in the fourth discharge cell 2030. It may be longer than the total length of the sub-address electrode 902b1.

As shown in FIG. 21, the barrier rib 212 may include the front electrodes 202 and 203, a horizontal barrier rib 212a and a vertical barrier rib 212b parallel to the address electrode X. FIG.

In this case, the exhaust hole 240 may overlap an area where the horizontal bulkhead 212a and the vertical bulkhead 212b cross each other.

In addition, the partition wall 212 may be omitted in the region where the exhaust hole 240 is formed.

Alternatively, as shown in FIG. 22, the exhaust hole 240 overlaps an area where the horizontal bulkhead 212a and the vertical bulkhead 212b intersect, while the exhaust hole 240 has the horizontal bulkhead 212a and the vertical bulkhead 212b. ) May be formed in the overlapping area.

On the other hand, one connection substrate may be electrically connected to the plurality of address electrodes (X). For example, as shown in FIG. 23, the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301 are connected to the X1 to Xa address electrodes of the plurality of address electrodes, and the second connecting substrate 2310. May be connected to Xa + 1 to Xb address electrodes among the plurality of address electrodes.

In this case, Xa + 1 to Xb address electrodes connected to the second connection substrate 2310 that do not overlap the exhaust hole 240 may not be divided.

On the other hand, the X1 to Xa address electrodes connected to the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301 overlapping the exhaust hole 240 may be divided.

Here, all of the X1 to Xa address electrodes connected to the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301 may not overlap the exhaust hole 240.

For example, when Xa of FIG. 23 is X10, that is, when X1 to X10 address electrodes of the plurality of address electrodes are connected to the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301, X1 to X10. The X4, X5, and X6 address electrodes of the address electrodes may overlap the exhaust hole 240, and the remaining X1, X2, X3, X7, X8, X9, and X10 address electrodes may not overlap the exhaust hole 240.

In this case, the X4, X5, and X6 address electrodes overlapping the exhaust hole 240 are divided, and the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301 are not overlapped with the exhaust hole 240. X1, X2, X3, X7, X8, X9, and X10 address electrodes connected to the same may also be divided. That is, at least one of the plurality of address electrodes does not overlap the exhaust hole 240 but may be divided.

In this case, the driving of supplying the data signal to the X1 to X10 address electrodes may be easier by dividing the address electrodes in units of the connecting substrate.

Also, the total lengths L10 + L11 of the X4, X5, and X6 address electrodes overlapping the exhaust holes 240 among the divided address electrodes are not overlapped with the exhaust holes 240, but are divided X1, X2, X3. , X7, X8, X9, and X10 may be smaller than the total length (L20 + L21) of the address electrode. More specifically, the length L10 of the first sub-address electrode 2410 of the X4, X5, and X6 address electrodes is the first sub-address electrode 2420 of the X1, X2, X3, X7, X8, X9, and X10 address electrodes. It may be smaller than the length (L20) of. Alternatively, the length L11 of the second sub-address electrode 2411 of the X4, X5, and X6 address electrodes may be the length of the second sub-address electrode 2421 of the X1, X2, X3, X7, X8, X9, and X10 address electrodes. It may be smaller than the length (L21).

In addition, as shown in FIGS. 23 and 25, X1 to X10 address electrodes connected to the first sub-connecting substrate 2300 and the second sub-connecting substrate 2301 are Xa + connected to the second connecting substrate 2310. It may include a portion extending by S20 than the 1 ~ Xb address electrode. This has been described in detail with reference to FIG. 16. Alternatively, the X1 to X10 address electrodes may not extend beyond the Xa + 1 to Xb address electrodes, and the ends thereof may be disposed at substantially the same positions.

In addition, the positions of the address electrodes divided into the plurality of sub-address electrodes among the address electrodes that do not overlap the exhaust hole 240 among the plurality of address electrodes will be described below.

For example, in Fig. 25, the X10 address electrode and the Xb address electrode will be compared. Here, both the X10 address electrode and the Xb address electrode do not overlap the exhaust hole 240.

Since the X10 address electrode is disposed between the exhaust hole 240 and the Xb address electrode, the distance D10 between the exhaust hole 240 and the X10 address electrode may be smaller than the distance D20 between the Xb address electrode and the exhaust hole 240. have. In this case, the X10 address electrode closer to the exhaust hole 240 may be divided.

In FIG. 25, when the X1 to X10 address electrodes do not extend beyond the Xa + 1 to Xb address electrodes, the length L30 of the Xa + 1 to Xb address electrodes is the total length L20 + L21 and L10 of the X1 to X10 address electrodes. + L11, L40 + L41).

Alternatively, as shown in FIG. 25, when the X1 to X10 address electrodes include a portion extending by S20 more than the Xb address electrode, S20 is the first sub-address electrode 2410 of the X5 address electrode divided into the exhaust hole 240. If the distance between the second sub-address electrode 2411 and the second sub-address electrode 2411 is larger than the sum of the length L10 of the first sub-address electrode 2410 of the X5 address electrode and the length L11 of the second sub-address electrode 2411 ( L0 + L11 may be greater than the length L30 of the Xb address electrode.

Alternatively, when the X1 to X10 address electrodes include a portion extending by S20 more than the Xb address electrode, S20 is the first sub-address electrode 2410 and the second sub of the X5 address electrode divided into the exhaust hole 240. The distance between the first sub address electrode 2420 and the second sub address electrode 2421 of the X1 address electrode but smaller than the distance between the address electrode 2411 and the first sub address electrode 2510 and the second of the X10 address electrode. When larger than the interval between the sub-address electrodes 2511, the sum L0 of the length L10 of the first sub-address electrode 2410 of the X5 address electrode and the length L11 of the second sub-address electrode 2411 (L0 + L11). Is smaller than the length L30 of the Xb address electrode, but the length L30 of the Xb address electrode is equal to the lengths L20 and L40 and the second subaddress of the first subaddress electrodes 2420 and 2510 of the X1 and X10 address electrodes. Length L2 of the electrodes 2421 and 2511 1, L41 may be less than the sum (L40 + L41, L20 + L21).

That is, (L40 + L41, L20 + L21)> L30> (L10 + L11).

26 to 31 are diagrams for describing the multi-plasma display panel and the multi-plasma display device. Hereinafter, a description thereof will be omitted for the parts described above in detail. For example, the features of the plasma display panel and the plasma display apparatus described above in detail with reference to FIGS. 1 to 25 may be applied to the following multi-plasma display panel and the multi-plasma display apparatus.

Referring to FIG. 26, as shown in (a), the multi-plasma display panel 10 may include a plurality of plasma display panels 100, 110, 120, and 130 disposed adjacent to each other.

The first-first driving unit 101 and the second-first driving unit 102 may supply driving signals to the first panel 100 among the plurality of plasma display panels 100 to 130. Here, the first-first driving unit 101 and the first-second driving unit 102 may be merged into one integrated driving unit.

In addition, the 2-1 driving unit 111 and the 2-2 driving unit 112 may supply driving signals to the second panel 110.

As described above, it is possible to set different driving units to supply driving signals to the plasma display panels 100, 110, 120, and 130, respectively.

In FIG. 26, each driving unit may be a driving board.

In addition, in the multi-plasma display device according to the present invention, as shown in FIG. 27, the first frame 200A is disposed on the rear surface of the first panel 100, that is, on the rear surface of the rear substrate of the first panel 100. The second frame 200B is disposed on the rear surface of the second panel 110, the third frame 200C is disposed on the rear surface of the third panel 120, and the fourth frame is disposed on the rear surface of the fourth panel 130. The frame 200D may be disposed.

The driving units 20A to 20D for supplying driving signals to the first, second, third and fourth panels 100 to 130 may be disposed on the rear surfaces of the first, second, third and fourth frames 200A to 200D.

In addition, as shown in FIG. 26, a seam area SA, 140, 150 may be formed between two adjacent plasma display panels. The core regions 140 and 150 may be referred to as a region between two adjacent plasma display panels.

Since the multi-plasma display panel 10 implements an image by arranging the individual plasma display panels 100 to 130 adjacent to each other, the core regions 140 and 150 are formed between two adjacent plasma display panels 100 to 130. Can be formed.

In each of the plasma display panels 100 to 130 included in the multi-plasma display panel 10 according to the present invention, the exhaust hole 240 may be formed in the effective area AA as described above.

Accordingly, the size of the core regions 140 and 150 in which images of the multi-plasma display panel 10 in which the plurality of plasma display panels 100 to 130 are disposed adjacent to each other is not displayed may be reduced. Therefore, since a more natural image can be realized in the multi display panel according to the present invention, the plasma display panel and the plasma display apparatus described in detail with reference to FIGS. 1 to 25 may be preferably applied to the multi plasma display panel and the multi plasma display apparatus. will be.

In addition, in each of the plasma display panels 100 to 130 included in the multi-plasma display panel 10 according to the present invention, the exhaust hole 240 is formed in the effective area AA while overlapping the exhaust hole 240. The address electrode may be divided into sub address electrodes. In addition, the divided sub-address electrodes may be supplied with data signals from different sub-connecting substrates. Accordingly, although the exhaust hole 240 is formed in the effective area AA, screen defects can be reduced.

The manufacturing method of the multi-plasma display panel is as follows.

Referring to FIG. 28, as in the method of FIG. 5, the front substrate 201 and the rear substrate 211 are bonded to each other after sealing the discharge space between the front substrate 201 and the rear substrate 211. A portion of the substrate 201 and the back substrate 211 may be cut along the predetermined cutting line CL. Here, it is possible to perform grinding along with cutting. For example, one long side and one short side of the front substrate 201 and the rear substrate 211 may be cut and ground.

Then, at the cutting portion as shown in FIGS. 28B and 28C, at least one of the front substrate 201 and the rear substrate 211 may be prevented from excessively protruding, thereby displaying an image. It can reduce the size of the parts that are not.

In addition, as shown in (b) and (c) of Figure 28 it is also possible to cut the seal 400 together in the process of cutting a part of the front substrate 201 and the rear substrate 211. As such, when the actual portion 400 is cut, the size of the portion where the image is not displayed may be further reduced.

A multi-plasma display panel may be manufactured by arranging a plurality of plasma display panels manufactured by the method as illustrated in FIG. 28 adjacent to each other.

For example, as in the case of FIG. 29, it is possible to arrange the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 in a 2 × 2 matrix form. Do.

In addition, it may be preferable to arrange the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 so that the cutting surfaces are adjacent to each other.

For example, the first panel 100, the second panel 110, the third panel 120, and the fourth panel 130 may be cut at the second short side SS2 and the second long side LS2, respectively. Grinding process can be performed.

In addition, the first panel 100 and the second panel 110 are disposed such that the second short side SS2 of the first panel 100 and the second short side SS2 of the second panel 110 are adjacent to each other. The third panel 120 and the fourth panel 130 may be disposed such that the second short side SS2 of the third panel 120 and the second short side SS2 of the fourth panel 130 are adjacent to each other.

In addition, the first panel 100 and the third panel 120 are disposed such that the second long side LS2 of the first panel 100 and the second long side LS2 of the third panel 120 are adjacent to each other. It is possible to arrange the second panel 110 and the fourth panel 130 such that the second long side LS2 of the second panel 110 and the second long side LS2 of the fourth panel 130 are adjacent to each other. .

In the multi-plasma display panel according to a comparative example different from the present invention, the observer may recognize that the image implemented in the multi-plasma display panel 10 appears discontinuously by the seam areas 140 and 150.

On the other hand, as in the case of FIG. 29 of the present invention, when the first panel 100, the second panel 110, the third panel 120 and the fourth panel 130 are disposed so that the cutting surface adjacent to each other In addition, the size of the core regions 140 and 150 of the multi-plasma display panel 10 may be reduced, thereby realizing a more natural image.

Here, the case in which the first panel 100, the second panel 110, the third panel 120 and the fourth panel 130 are arranged in a 2 × 2 matrix form is described. It is possible to arrange a plurality of panels in various forms such as 1 × 2 matrix form or 2 × 1 matrix form.

For example, or as in the case of FIG. 30, it is possible to arrange the panels in the form of a 4 × 4 matrix. Here, an example of a 4x4 matrix form is described, but a matrix form of 3x3 or more may be applied substantially the same.

As such, when configuring a multi-plasma display panel using a larger number of panels, it is possible to arrange the panels in substantially the same pattern.

The first panel 1000, the second panel 1010, the fifth panel 1100, and the sixth panel 1110 of the first to sixteenth panels 1000 to 1330 arranged in a 4 × 4 matrix form in FIG. 30 are illustrated. A case is described as an example of FIG. 31.

Referring to FIG. 31, the first panel 1000 and the second panel 1010 are disposed adjacent to each other in the first direction, and the first panel 1000 and the fifth panel 1100 intersect the first direction. The sixth panel 1110 and the second panel 1010 are disposed adjacent to each other in two directions, and the sixth panel 1110 and the fifth panel 1100 are disposed adjacent to each other in the second direction. It can be arranged adjacent to each other.

In addition, in the first panel 1000, the second panel 1010, the fifth panel 1100, and the sixth panel 1110, the first and second short sides SS1 and SS2, and the first and second long sides LS1, The cutting and grinding process may be performed at the LS2) side.
