Each of the plasma display panels 100 to 130 may implement an image using a frame including a plurality of subfields.

5, the first, second, third and fourth plasma display panels 100 to 130 include a plurality of second electrodes 202 (Y) and 203 (Z) crossing the plurality of first electrodes 202 213, and X may be formed on the rear substrate 211.

Here, the first electrodes 202 and 203 may include the scan electrodes 202 and Y and the sustain electrodes 203 and Z, and the second electrode 211 may be referred to as an address electrode.

The discharge currents of the scan electrodes 202 and the sustain electrodes 203 and the sustain electrodes 203 are applied to the front substrate 201 on which the scan electrodes 202 and the sustain electrodes 203 and the sustain electrodes Z are formed. ) And the sustain electrodes 203, Z may be disposed on the lower dielectric layer 204. In this case,

The front substrate 201 on which the upper dielectric layer 204 is formed may be provided with a protective layer 205 for facilitating discharge conditions. The protective layer 205 may include a material having a high secondary electron emission coefficient, for example, a magnesium oxide (MgO) material.

Address electrodes 213 and X are formed on the rear substrate 211 and address electrodes 213 and X are formed on the rear substrate 211 on which the address electrodes 213 and X are formed. The lower dielectric layer 215 may be formed.

Barrier ribs 212 such as a stripe type, a well type, a delta type, and a honeycomb type for partitioning a discharge space, that is, a discharge cell, are formed on an upper portion of the lower dielectric layer 215 . Accordingly, a first discharge cell that emits red (R) light, a second discharge cell that emits blue (B) light, and a second discharge cell that emits green (Green) light are provided between the front substrate 201 and the rear substrate 211, : G) a third discharge cell that emits light, or the like.

On the other hand, in the discharge cell, the address electrode 213 may cross the scan electrode 202 and the sustain electrode 203. That is, the discharge cells are formed at the intersections of the address electrodes 213 with the scan electrodes 202 and the sustain electrodes 203.

A predetermined discharge gas may be filled in the discharge cells partitioned by the barrier ribs 212.

In addition, in the discharge cells partitioned by the barrier ribs 212, a phosphor layer 214 that emits visible light for image display upon address discharge may be formed. For example, a first phosphor layer for generating red light, a second phosphor layer for generating blue light, and a third phosphor layer for generating green light may be formed.

The width and thickness of the address electrode 213 formed on the rear substrate 211 may be substantially constant in width or thickness but may be different from the width or thickness of the inside of the discharge cell outside the discharge cell . For example, the width or thickness inside the discharge cell may be wider or thicker than that outside the discharge cell.

When a predetermined signal is supplied to at least one of the scan electrode 202, the sustain electrode 203, and the address electrode 213, a discharge may occur in the discharge cell. When a discharge is generated in the discharge cell, ultraviolet rays can be generated by the discharge gas filled in the discharge cell, and such ultraviolet rays can be irradiated to the phosphor particles of the phosphor layer 214. Then, the phosphor particles irradiated with the ultraviolet rays emit visible light, so that a predetermined image can be displayed on the screen of the plasma display panel 100.

An image frame for realizing image gradation in a plasma display panel will be described below.

Referring to FIG. 6, a frame for implementing a gray level of an image may include a plurality of subfields (SF1 to SF8).

In addition, a plurality of subfields are divided into an address period for selecting a discharge cell in which a discharge will not occur or a discharge period for selecting a discharge cell in which a discharge occurs, and a sustain period for implementing a gray level according to the number of discharges Period).

For example, when an image is to be displayed at 256 gray levels, one frame is divided into eight subfields (SF1 to SF8) as shown in FIG. 6, and eight subfields (SF1 to SF8) And a sustain period.

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

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

On the other hand, the number of the sustain signals supplied in the sustain period may be adjusted to set the weight of the corresponding subfield. That is, a predetermined weight can be given to each subfield using the sustain period. For example, the weight of the first subfield is set to 2 ⁰ , and the weight of the second subfield is set to 2 ¹ , so that the weight of each subfield is 2 ⁿ (n = 0, 1, 2, 3, 4, 5, 6, 7). By adjusting the number of the sustain signals supplied in the sustain period of each sub-field in accordance with the weight value in each sub-field, it is possible to implement various image gradations.

Here, in FIG. 6, only one image frame is composed of eight subfields. However, the number of subfields forming one image frame may be variously changed. For example, one video frame may be composed of 12 sub-fields from the first sub-field to the 12th sub-field, or one video frame may be composed of 10 sub-fields.

In FIG. 6, the subfields are arranged according to the increasing order of the weights in one image frame. Alternatively, in one image frame, the subfields may be arranged in decreasing order of weights, The subfields may be arranged regardless of the subfields.

Driving waveforms for driving the respective plasma display panels 100 to 130 will be described below.

7, in a reset period (RP) for initializing at least one sub-field among a plurality of sub-fields of a frame, a 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 whose voltage gradually increases and a falling ramp signal Ramp-Down RD whose voltage gradually falls.

For example, the rising ramp signal RU may be supplied to the scan electrode in the set-up period SU of the reset period, and the falling ramp signal RD may be supplied to the scan electrode during the set-down period SD after the set- .

When a rising ramp signal is supplied to the scan electrode, a weak dark discharge (i.e., setup discharge) occurs in the discharge cell due to the rising ramp signal. By this set-up discharge, the distribution of wall charges (Wall Charge) in the discharge cells can be made uniform.

When a falling ramp signal is supplied to the scan electrode after the rising ramp signal is supplied, a weak erase discharge (setdown discharge) occurs in the discharge cell. Due to the set-down discharge, wall charges can be uniformly left in the discharge cells to such an extent that address discharge can occur stably.

In the address period AP after the reset period, a 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 the address period, the scan signal Sc falling from the voltage of the scan reference signal Ybias may be supplied to the scan electrode.

The pulse width of the scan signal supplied to the scan electrodes in the address period of at least one subfield may be different from the pulse width of the scan signals of the other subfields. For example, the width of the scan signal in the subfields positioned later in time may be smaller than the width of the scan signal in the subfields positioned in front. In addition, the decrease in the scan signal width according to the arrangement order of the subfields can be made progressively, such as 2.6 mu s, 2.3 mu s, 2.1 mu s, 1.9 mu s, or the like, or 2.6 mu s, 2.3 mu s, 1.9 占 퐏, 1.9 占 퐏, and so on.

As described above, 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 such a scan signal and a data signal are supplied, a wall voltage due to wall charges generated in the reset period and a voltage difference between the scan signal and the data signal are added, and an address discharge may be generated in the discharge cell to which the data signal is supplied .

In addition, in the address period in which the address discharge occurs, the sustain reference signal Zbias may be supplied to the sustain electrode in order to effectively generate the address discharge 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, the sustain signal may be alternately supplied to the scan electrode and the sustain electrode.

When the sustain signal is supplied, the wall voltage in the discharge cell and the sustain voltage (Vs) of the sustain signal are added to the discharge cells selected by the address discharge. When the sustain signal is supplied, a sustain discharge is generated between the scan electrode and the sustain electrode Discharge may occur.

A method of manufacturing a multi-plasma display apparatus according to the present invention will be described below.

8, a seal layer 400 is formed on at least one edge of a front substrate 201 and a rear substrate 211 on which an exhaust hole 200 is formed as shown in FIG. The front substrate 201 and the rear substrate 211 can be bonded together.

Thereafter, an exhaust tip (not shown) is connected to the exhaust hole 200, and an exhaust pump (not shown) can be connected to the exhaust tip.

In addition, an impurity gas remaining in a discharge space between the front substrate 201 and the rear substrate 211 can be discharged to the outside by using an exhaust pump, and argon (Ar), neon (Ne), xenon (Xe) Or the like can be injected into the discharge space.

In this way, the discharge space between the front substrate 201 and the rear substrate 211 can be sealed.

9 (a), the front substrate 201 and the rear substrate 211 are joined together, and a part of the front substrate 201 and the rear substrate 211 is cut along a predetermined cutting line CL1 . Here, grinding can be performed together.

9 (b), it is possible to prevent at least one of the front substrate 201 and the rear substrate 211 from being excessively protruded. Thus, the size of the portion where the image is not displayed Can be reduced.

Meanwhile, it is also possible to cut the seal layer 400 together in the process of cutting off the front substrate 201 and the rear substrate 211 as shown in FIG. 9 (a). As described above, if the seal layer 400 is cut, the size of the portion where the image is not displayed can be further reduced.

Thereafter, a flexible substrate such as a TCP (Tape Carrier Package) or an FPC (Flexible Printed Circuit) is electrically connected to the exposed sides of the electrodes 202 and 203 as shown in FIG. 9 (b) A drive signal can be supplied.

When a plurality of plasma display panels manufactured by the above-described method are disposed adjacent to each other and fixed, the multi-plasma display device can be completed.

FIGS. 10 to 20 are views for explaining the driving method of the multi-plasma display apparatus in more detail. Hereinafter, the description of the parts described in detail above will be omitted.

It is possible to change the data in the boundary area between two adjacent plasma display panels.

For example, as shown in FIG. 10, when the first panel 100 and the second panel 110 are adjacent to each other, data can be manipulated in the boundary area between the first panel 100 and the second panel 110 It is.

The area adjacent to the second panel 110 in the first panel 100 is referred to as a first area A1 and the area adjacent to the first panel 100 in the second panel 110 is referred to as a second area A2 The data in the first area A1 and the data in the second area A2 can be changed differently. Here, the first area A1 and the second area A2 may include at least one discharge cell.

10, the area including the outermost discharge cell closest to the second panel 110 in the first panel 100 is referred to as a first area A1, and the area including the outermost discharge cell in the second panel 110 is referred to as a first area The data of the first area A1 and the data of the second area A2 can be exchanged when the area including the outermost discharge cell closest to the first panel 100 is referred to as a second area A2. In other words, a data signal supplied to the outermost address electrode Xm closest to the second panel 110 among the plurality of address electrodes arranged in the first panel 100 is divided into a plurality of The data signal supplied to the outermost address electrode X1 closest to the first panel 100 among the address electrodes of the first panel 100 is changed. The meaning of exchanging the data signal is that the data signal to be supplied to the outermost address electrode Xm of the first panel 100 is supplied to the outermost address electrode X1 of the second panel 110, The data signal to be supplied to the outermost address electrode X1 of the panel 110 may be supplied to the outermost address electrode Xm of the first panel 100. [

That is, a part of data corresponding to the first panel 100 is supplied to the second panel 110, and a part of the data corresponding to the second panel 110 is supplied to the first panel 100.

For example, when the case of FIG. 3 is connected to the case of FIG. 10, the first driving unit 101 disposed on the rear surface of the first plate 300 disposed on the rear surface of the first panel 100, A part of the data corresponding to the second panel 110 is supplied to the address electrodes of the first panel 100 and the second panel 310 disposed on the back of the second panel 110, 1 driver 111 supplies a part of the data corresponding to the first panel 100 to the address electrode of the second panel 110. [

In this case, the image displayed on the screen of the multi-plasma display device will be described below.

Assume that an image of a predetermined pattern as shown in FIG. 11 (a) is implemented over the first panel 100 and the second panel 110.

In this case, a part of the data of the first panel 100 is supplied to the second panel 110 as shown in (b) of FIG. 11, so that an image to be displayed on the first panel 100 is supplied to the second panel 110 And an image to be displayed on the second panel 110 may be displayed on the first panel 100. [ That is, a part of data corresponding to the first panel 100 and a part of data corresponding to the second panel 110 are exchanged with each other.

In this case, an image as shown in FIG. 11C can be implemented.

That is, a part of the image of the first panel 100 and a part of the image of the second panel 110 are mixed with each other at the boundary between the first panel 100 and the second panel 110. In this case, the image implemented at the boundary portion between the first panel 100 and the second panel 110 may be relatively blurry. As described above, the image formed at the center portion of the first panel 100 and the center portion of the second panel 110 is clear, whereas the blurred image is formed at the boundary portion between the first panel 100 and the second panel 110 It is possible to obtain a visual effect in which the boundary between the first panel 100 and the second panel 110 is reduced.

As described above, when the method of mixing the image of the first panel 100 and the image of the second panel 110 at the boundary portion between the first panel 100 and the second panel 110 is used, It is possible to obtain a visual effect in which the boundary between the first panel 100 and the second panel 110 is reduced.

A case where a dummy discharge cell (DC) is formed in a dummy area DA outside the active area AA will be described below.

The effective area AA is a region in which an image is formed by a discharge occurring in the discharge cell, and a phosphor layer, a scan electrode, a sustain electrode, and an address electrode may be formed in each discharge cell in the effective area AA .

At least one dummy discharge cell DC may be disposed in the dummy area outside the effective area AA. The dummy area is an area where the image is not substantially displayed, and no discharge is generated in the dummy discharge cell, or a phosphor layer is not formed even if a discharge is generated, so that visible light may not be generated. Alternatively, the dummy area DA may be covered by a black frame disposed on the front surface of the panel.

Since no image is implemented in the dummy area DA, there is no need to change the data supplied to the dummy discharge cells DC or there is no need to supply data to the dummy discharge cells DC.

12, even in the case where the dummy discharge cells DC are arranged in the dummy area DA outside the effective area AA, at least the outermost discharge cells in the effective area AA of the first panel 100 It may be preferable to exchange data to be supplied and data supplied to at least the outermost discharge cells in the effective area AA of the second panel 110 adjacent to the first panel 100. [

In addition, when the dummy area DA is disposed outside the effective area AA, the outermost address electrode may be disposed in the dummy area DA. For example, as shown in FIG. 12, the Xm-1 address electrode and the Xm address electrode may be disposed in the dummy area DA of the first panel 100. FIG. In addition, the X1 address electrode and the X2 address electrode may be disposed in the dummy area DA of the second panel 110. [

The data signal supplied to the outermost address electrode Xm-2 closest to the second panel 110 in the effective area AA of the first panel 100 It may be preferable to exchange data signals supplied to at least the outermost address electrode X3 closest to the first panel 100 within the effective area AA of the second panel 110. [

13, the data signal supplied to the plurality of address electrodes adjacent to the second panel 110 among the plurality of address electrodes of the first panel 100 is supplied to the address electrodes of the plurality of address electrodes of the second panel 110 It is also possible to exchange data signals supplied to a plurality of address electrodes adjacent to one panel 100.

For example, among the plurality of address electrodes of the first panel 100, from the outermost address electrode Xm adjacent to the second panel 110 to the farthest address electrode Xm, further five address electrodes are provided in the direction away from the second panel 110, That is, the data signal supplied to the address electrodes Xm-1 to Xm-5 is applied from the outermost address electrode X1 adjacent to the first panel 100 among the plurality of address electrodes of the second panel 110 to the first panel 100 The data signal supplied to the five address electrodes, that is, the address electrodes X2 to X6, can be exchanged.

Although only the case of exchanging the data signal of the six address electrodes in each panel is described here, the number of the address electrodes to which the data signal is exchanged can be changed.

Alternatively, it is possible to select a discharge cell for exchanging a data signal in one address electrode.

For example, as in the case of FIG. 14, data signals of one discharge cell can be exchanged between the first panel 100 and the second panel 110 in the longitudinal direction of the address electrodes. Specifically, the data of the discharge cells intersecting with Xm-2, Xm-1, and Xm address electrodes among the discharge cells corresponding to the Ya scan electrode in the first panel 100 correspond to the Ya scan electrode in the second panel 110 X2, and X3 among the discharge cells that are adjacent to the address electrodes X1, X2, and X3.

In the first panel 100, data of the discharge cells intersecting with Xm-2, Xm-1, and Xm address electrodes among the discharge cells corresponding to the Ya + 1 scan electrode and data of Ya + 1 scan The data of the discharge cells crossing the X1, X2, and X3 address electrodes among the discharge cells corresponding to the electrodes can be maintained as they are. That is, data is not exchanged.

2, Xm-1, and Xm among the discharge cells corresponding to the Ya + 2 scan electrodes in the first panel 100, data of the discharge cells intersecting with the address electrodes Ya + 2 X2, and X3 among the discharge cells corresponding to the electrodes.

The data exchange between the first panel 100 and the third panel 120 adjacent to each other in the direction parallel to the scan electrodes will be described below. Hereinafter, the description of the parts described in detail above will be omitted.

[

When the dummy area DA is disposed outside the effective area AA at the boundary between the first panel 100 and the third panel 120, the outermost scan electrode may be disposed in the dummy area DA. have. For example, as shown in FIG. 16, a Yn scan electrode may be disposed in the dummy area DA of the first panel 100. FIG. In addition, a Y1 scan electrode may be disposed in the dummy area DA of the third panel 120. FIG.

The discharge cells corresponding to the outermost scan electrode Yn-1 closest to the third panel 120 in the effective area AA of the first panel 100 The data signal to be supplied is exchanged with a data signal supplied to a discharge cell corresponding to at least the outermost scan electrode Y2 closest to the first panel 100 in the effective area AA of the third panel 120 Which may be desirable.

Alternatively, as in the case of FIG. 17, data signals of one discharge cell may be exchanged between the first panel 100 and the third panel 120 in the longitudinal direction of the scan electrodes. In detail, the data of the discharge cells crossing the address electrodes X1, X3, and X5 among the discharge cells corresponding to the Yn and Yn-1 scan electrodes in the first panel 100 are applied to the Y1 and Y2 scan electrodes X3, and X5 among the discharge cells corresponding to the address electrodes X1, X3, and X5.

In the first panel 100, data of the discharge cells crossing the X2, X4, and X6 address electrodes among the discharge cells corresponding to Yn and Yn-1 scan electrodes and data of the discharge cells crossing the Y1 and Y2 scan electrodes in the third panel 120 The data of the discharge cells crossing the X2, X4, and X6 address electrodes of the corresponding discharge cells can be maintained as it is.

The contents of FIG. 18 have been fully described by the foregoing description.

On the other hand, in a selected subfield among a plurality of subfields, data may be exchanged at boundary portions of adjacent two plasma display panels, and data may not be exchanged in the remaining subfields.

For example, as shown in FIG. 19, when one frame is composed of a total of eight subfields SF1 to SF8, data is exchanged in the first to fourth subfields SF1 to SF4, To 8 subfields SF5 to SF8, data may not be exchanged.

Preferably, data is exchanged in any of the A subfields among the plurality of subfields of one frame, and data is not exchanged in the B subfield having a higher weight than the A subfield. This is because the amount of data corresponding to the A subfield having a low weight may be larger than the amount of data corresponding to the B subfield. That is, since the A subfield has a lower weight than the B subfield, the possibility of being selected when implementing a predetermined gray level is higher than that of the B subfield.

As described above, it is more likely to exchange data in a low-gradation sub-field having a high possibility of being selected to obtain the effect of making the size of the boundary portion of the adjacent plasma display panel smaller.

Alternatively, as shown in FIG. 20, data may be exchanged in any of a plurality of frames, and data may not be exchanged in the remaining frames. Preferably, data can be exchanged according to a predetermined period. For example, it is possible to exchange data in every one frame or exchange data in one frame every three frames.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

It should be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, And all changes or modifications derived from equivalents thereof should be construed as being included within the scope of the present invention.
