In order to supply the driving signal to the electrode, it may be preferable that the pad areas of the scan electrode and the sustain electrode are located at substantially the same area.

For example, as in the case of FIG. 5, the scan electrodes Y1 to Yn and the sustain electrodes Z1 to Zn may be formed on one side of the panel (left side in FIG. 5).

In this case, as in the case of FIG. 6, the first, second, third, and fourth plasma display panels 100 of the 1-2, 2-2, 3-2, and 4-2 driving units 102, 112, 122, and 132 are respectively used. 130 may be connected to the scan electrode and the sustain 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.

The address electrodes 213 and X are formed on the rear substrate 211, and the address electrodes 213 and X are covered on the upper side of the rear substrate 211 on which the address electrodes 213 and X are formed. A lower dielectric layer 215 may be formed that insulates X).

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.

An image frame for implementing gradation of an image in a plasma display panel is described below.

Referring to FIG. 8, 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 through SF8 as shown in FIG. 8, and each of the eight subfields SF1 through 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. 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.

In FIG. 8, only one image frame is composed of eight subfields, and is described and described. 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. 8, 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.

The driving waveforms for driving the respective plasma display panels 100 to 130 are as follows.

Referring to FIG. 9, in a 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 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.

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 least one of the front substrate 201 and the rear substrate 211 may be prevented from excessively protruding from the cut portion as illustrated in FIGS. 11B and 11C, 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 11 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.

15 to 44 are views for explaining the multi-plasma display device according to the present invention in more detail. In the following, description of the parts described in detail above will be omitted.

In addition, hereinafter, the case of the first panel 100 and the second panel 110 will be described as an example, but the following contents may be applied to the case of two adjacent panels. For example, the following descriptions are made of the first panel 100 and the third panel 120, the second panel 110 and the fourth panel 130, or the third panel 120 and the fourth panel 130. In the case of the same it is possible to apply.

15 and 16, the first panel 100 and the first panel 100 in the region between the first panel 100 and the second panel 110 adjacent to each other in the first direction DR1, that is, in the core region Seam. The edges of the front substrates 201A and 201B of the second panel 110 may be cut.

The interval between the front surface of the front substrate 201A of the first panel 100 and the front surface of the front substrate 201B of the second panel 110 is referred to as the first interval D2, and the solid layers 400A, In the region adjacent to 400B, the distance between the front substrate 201A of the first panel 100 and the front substrate 201B of the second panel 110 is defined as the second distance D1 in the first direction DR1. Let's assume

Here, the first interval D2 may be greater than the second interval D1.

That is, the first and second panels 100 and 110 may include a portion in which the widths of the front substrates 201A and 201B decrease in the first direction DR1.

In other words, in the region where the first panel 100 and the second panel 110 are adjacent to each other, the front substrates 201A and 201B of the first and second panels 100 and 110 are adjacent to the real layers 400A and 400B. It may include a portion of the width decreases in the first direction DR1 toward the front of the front substrate 201A, 201B in the region.

Here, the portion where the width of the front substrates 201A and 201B decreases in the first direction DR1 may be referred to as the reduced portions 500A and 500B. The reduced portion of the first panel 100 may be referred to as a first reduced portion 500A, and the reduced portion of the second panel 110 may be referred to as a second reduced portion 500B.

The first reduction portion 500A in the second direction DR2 may overlap at least one discharge cell in the first panel 100, and the second reduction portion 500B in the second direction DR2 may be the second. The panel 110 may overlap at least one discharge cell.

In addition, the width L2 of the first reduction portion 500A in the first direction DR1 may be larger than the width L1 of the seal layer 400A. This may be equally applied to the second panel 110.

In this case, as in the case of FIG. 17, light generated in the first and second cells C1 and C2 of the first panel 100 is inclined to the inclined surface of the first reduction portion 500A of the first panel 100. It may be refracted to travel forward of the first panel 100. This may be equally applicable to the second panel 110.

Accordingly, it is possible to obtain a visual effect in which a predetermined image is realized in the boundary region of the first panel 100 and the second panel 110, that is, the core region, and obtain a visual effect in which the core region becomes smaller. It is possible to.

For example, as shown in FIG. 18A, first and second reduction parts 500A and 500B are formed on the front substrates 201A and 201B of the first panel 100 and the second panel 110. If not, the core regions 140 and 150 may be prominent.

On the other hand, when the first and second reduction portions 500A and 500B are formed on the front substrates 201A and 201B of the first panel 100 and the second panel 110, the case of FIG. 18B is illustrated. As described above, the optical regions in which the core regions 140 and 150 appear faint or small can be obtained.

Accordingly, it is possible to improve the image quality of the image implemented on the screen of the multi-plasma display apparatus.

Referring to FIG. 19, a resin layer 600 may be disposed between the front substrate 201A of the first panel 100 and the front substrate 201B of the second panel 110. Here, the resin layer 600 may include a transparent material and may transmit light.

In detail, a resin material may be applied to the cut portions of the front substrate 201A of the first panel 100 and the front substrate 201B of the second panel 110 to form the resin layer 600.

In other words, the resin layer 600 may be formed in the first reduction portion 500A of the first panel 100 and the second reduction portion 500B of the second panel 110.

The resin layer 600 may include the first resin layer 600A and the second resin layer 600B as in the case of FIG. 20.

The first resin layer 600A is adjacent to the first reduction portion 500A of the front substrate 201A of the first panel 100, and the second resin layer 600B is the front substrate of the second panel 110 ( And may be adjacent to the second reduction portion 500B of 201B.

The first resin layer 600A and the second resin layer 600B may be spaced apart from the predetermined distance D3 in the first direction DR1.

As such, when dividing the resin layer 600 into the first resin layer 600A and the second resin layer 600B, the first panel 100 and the second panel 110 are mounted on the holder in the multi-plasma display device. It may be easy to adjust the position of the first panel 100 and the second panel 110 in one state.

Referring to FIG. 21, filters 220, 221, 222, and 223 may be disposed in front of each plasma display panel 100 to 130. For example, a first filter 220 is disposed in front of the first panel 100, a second filter 221 is disposed in front of the second panel 110, and a front of the third panel 120. The third filter 222 may be disposed in the fourth filter 130, and the fourth filter 223 may be disposed in front of the fourth panel 130.

The first, second, third, and fourth filters 220, 221, 222, and 223 may be glass-type filters including a glass substrate, or may be film-type filters including a resin substrate. Hereinafter, a case in which the first, second, third, and fourth filters 220, 221, 222, and 223 are film filters will be described as an example.

Referring to FIG. 22, the first numerical layer 600A includes the first filter 220 disposed in front of the first panel 100 and the first reduced portion 500A of the front substrate 201A of the first panel 100. ) And the second numerical layer 600B is disposed between the second filter 221 and the front panel 201B of the second panel 110 disposed in front of the second panel 110. It may be arranged between 500B.

In addition, a first adhesive layer 700A is disposed between the front substrate 201A of the first panel 100 and the first filter 220, and the front substrate 201B and the second filter of the second panel 110 are disposed. The second adhesive layer 700B may be disposed between the 221s.

In addition, the first adhesive layer 700A may include a portion positioned between the first resin layer 600A and the first filter 220, and the second adhesive layer 700B may be formed of the second resin layer 600B. It may include a portion located between the second filter 221.

Referring to FIG. 23, a first prism sheet 800A and 800B may be disposed between the first resin layer 600A and the first filter 220 and between the second resin layer 600B and the second filter 221, respectively. ) May be arranged. Here, the prism sheet is positioned between the first prism sheet 800A and the second resin layer 600B and the second filter 221 positioned between the first resin layer 600A and the first filter 220. The second prism sheet 800B may be included.

In addition, the width L3 of the first prism sheet 800A in the first direction DR1 may be larger than the width L1 of the seal layer 400A.

The prism sheets 800A and 800B may include a prism portion 810 that refracts incident light.

The prism portions 810 of the prism sheets 800A and 800B may be located at the filters 220 and 221.

As in the case of FIG. 24, the light incident at the angle of θ1 from the panels 100 and 110 to the prism sheets 800A and 800B enters the prism sheets 800A and 800B, and the traveling angle decreases to θ2, again. The propagation angle may be approximately right angle while passing through the prism portion 810 of the prism sheets 800A and 800B.

In addition, in the second direction DR2, the first and second prism sheets 800A and 800B may overlap at least one discharge cell.

In this case, as in the case of FIG. 25, the light generated in the first and second cells C1 and C2 of the first panel 100 is applied to the inclined surface of the first reduction portion 500A of the first panel 100. It is possible to be refracted and advance toward the front of the first panel 100, and then the traveling angle becomes approximately right angle while passing through the first prism sheet 800A. This may be equally applicable to the second panel 110.

Accordingly, it is possible to obtain a visual effect in which the boundary region of the first panel 100 and the second panel 110, that is, the core region, becomes smaller.

Referring to FIG. 26, the first reduction portion 500A in the first direction DR1 extends by a predetermined length D4 more than the first prism sheet 800A in the direction toward the center of the first panel 100. It may include. In addition, the first resin layer 600A in the first direction DR1 may also include a portion extending further by a predetermined length than the first prism sheet 800A in the direction toward the center of the first panel 100. The same may be applied to the second panel 110.

In such a case, it is possible to prevent excessive screen distortion by the first prism sheet 800A.

Referring to FIG. 27, a portion of the first prism sheet 800A extending in the first direction DR1 extends by a predetermined length D5 in a direction away from the center of the first panel 100 than the first reduction portion 500A. It may include. The same may be applied to the second panel 110.

In this case, the visual effect of the smaller size of the core region can be further increased.

Referring to FIG. 28, the prism sheet 800 may be located in an area between two adjacent panels.

For example, between the first panel 100 and the second panel 110 adjacent to each other in the first direction DR1, the first panel 100 and the third panel 120 adjacent to the second direction DR2 to each other. Between the second panel 110 and the fourth panel 130 adjacent to each other in the second direction DR2, and the area between the third panel 120 and the fourth panel 130 adjacent to the first direction DR1. It may be possible for the prism sheet 800 to be disposed.

Referring to FIG. 29, reflective layers 900A and 900B may be disposed on rear surfaces of the rear substrates 211A and 211B of the first and second panels 100 and 110. Preferably, the first reflective layer 900A is attached to the rear surface of the rear substrate 211A of the first panel 100, and the second reflective layer 900B is the rear surface of the rear substrate 211B of the second panel 110. It is possible to be attached to.

The reflective layers 900A and 900B may reflect light generated from the first and second panels 100 and 110 so that the size of the core area SA between two adjacent plasma display panels may be reduced optically. .

The first and second reflective layers 900A and 900B may be disposed in an area overlapping the seal layers 400A and 400B for bonding the front substrates 201A and 201B and the rear substrates 211A and 211B.

The first and second reflective layers 900A and 900B may be mirrors that reflect incident light.

Although not shown, in order to attach the first and second reflective layers 900A and 900B to the rear substrates 211A and 211B, an adhesive layer is provided between the first and second reflective layers 900A and 900B and the rear substrates 211A and 211B. Can be formed. Here, it may be preferable that the adhesive layer has light transmittance for effective light reflection of the first and second reflective layers 900A and 900B.

Alternatively, the first and second reflective layers 900A and 900B may be coated on the rear substrates 211A and 211B. For example, although not shown, coating may be performed by applying a reflective material to the back substrates 211A and 211B using a predetermined coating means. Here, the reflective material may be a mixture of a material capable of reflecting light, such as a metal material, in a solvent. In addition, the reflective material may include a pigment.

Thereafter, when the coated reflective material is dried, first and second reflective layers 900A and 900B may be formed.

The width L1 of the seal layers 400A and 400B and the width L4 of the first and second reflective layers 900A and 900B may be different in the first direction DR1. Preferably, the width L4 of the first and second reflective layers 900A and 900B in the first direction DR1 may be larger than the width L1 of the seal layers 400A and 400B.

In addition, the first and second reflective layers 900A and 900B may overlap the partitions 212A and 212B in the second direction DR2. Preferably, the first and second reflective layers 900A and 900B may overlap the discharge cells partitioned by the partition walls 212A and 212B. Here, that the first and second reflective layers 900A and 900B overlap the discharge cells may mean that the first and second reflective layers 900A and 900B overlap the phosphor layers 214A and 214B. In this case, as in the case of FIG. 30, the first and second reflective layers 900A and 900B can more effectively reflect light generated in the discharge cells. In FIG. 30, the light reflection path is indicated by a dotted line.

In addition, the width L4 of the first and second reflective layers 900A and 900B in the first direction DR1 may be smaller than the width L3 of the first and second prism sheets 800A and 800B.

In this case, it is possible to reduce the possibility that the light reflected by the first and second reflective layers 900A and 900B does not pass through the first and second prism sheets 800A and 800B, thereby suppressing deterioration of the image quality of the image by the reflected light. have.

In addition, in the first direction DR1, the width L2 of the first and second reduction parts 500A and 500B may be greater than the width L4 of the first and second reflective layers 900A and 900B.

In addition, the reflective layer 900 may be located in an area between two adjacent plasma display panels. For example, as in the case of FIG. 31, the reflective layer 900 may include a first panel adjacent in the second direction DR2 between the first panel 100 and the second panel 110 adjacent in the first direction DR1. Between the panel 100 and the third panel 120, between the second panel 110 and the fourth panel 130 adjacent in the second direction DR2 and the third panel adjacent in the first direction DR1 ( It may be possible to be disposed in an area between the 120 and the fourth panel 130.

Referring to FIG. 32, a light guide plate 1400 may be disposed between the adjacent first panel 100 and the second panel 110.

The light guide plate 1400 may include a portion located between the first resin layer 600A and the second resin layer 600B in the first direction DR1.

The light guide plate 1400 may be exposed to the side surface. In other words, the user may visually sense the side surface of the light guide plate 1400 in front of the multi-plasma display device according to the present invention.

The light guide plate 1400 may change a traveling direction of incident light.

For example, as in the case of FIG. 33, when the light source 1420 disposed on the side of the light guide plate 1400 emits light toward the side of the light guide plate 1400, the light guide plate 1400 is separated from the light source 1420. The incident light can diverge forward. To this end, the light guide plate 1400 may include a plurality of reflective particles 1410 for scattering incident light. In FIG. 33, the light traveling direction is indicated by an arrow.

When the light guide plate 1400 having the above characteristics is disposed between the first panel 100 and the second panel 110, as shown in FIG. 34, light generated inside the panel and exiting to the side of the panel is emitted. The light guide plate 1400 may travel toward the side of the light guide plate 1400, that is, in front of the panel.

Meanwhile, the light generated inside the panel and exiting to the side of the rear substrate 211 of the panel may travel to the rear of the panel by the light guide plate 1400. As such, the light propagated to the rear of the panel by the light guide plate 1400 has a relatively low contribution to obtaining a visual effect in which a predetermined image is realized in the core region.

Accordingly, as shown in FIG. 35, the light guide plate 1400 overlaps the front substrates 201A and 201B and the rear substrates 211A and 211B in the first direction DR1, and the light guide plate 1400 and the front surface thereof. The width L5 of the portion where the substrates 201A and 201B overlap may be greater than the width L6 of the portion where the light guide plate 1400 and the rear substrates 211A and 211B overlap.

Alternatively, as shown in FIG. 36, the light guide plate 1400 overlaps the front substrates 201A and 201B and the seal layers 400A and 400B in the first direction DR1 and does not overlap the rear substrates 211A and 211B. It is possible not to.

The manufacturing method of the resin layer 600 will be described below with reference to the accompanying drawings.

First, as in the case of FIG. 37A, a portion of the front substrate 201 may be cut. For example, the reduction portion 500 may be formed by cutting the edge region of the front surface of the front substrate 201 using a method such as laser cutting or ultrasonic cutting.

Thereafter, as shown in FIG. 37B, the resin material layer 1500 may be formed by applying a resin material to the cut portion of the front substrate 201, that is, the reduced portion 500.

Thereafter, the resin material layer 1500 may be irradiated with ultraviolet rays (Ultraviolet Ray, UV) to cure the resin material layer 1500 to form the resin layer 600.

Thereafter, as in the case of FIG. 37C, the prism sheet 800 and the filter 220 may be disposed on the resin layer 600 or the front substrate 201.

The resin layer 600, that is, the first and second resin layers 600A and 600B may include the front substrates 201A and 201B, the seal layers 400A and 40B, and the rear substrates of the first and second panels 100 and 110. It is possible to contact with 211A, 211B). In this case, the first and second resin layers 600A and 600B can prevent corrosion of the seal layers 400A and 400B and electrodes not shown, and protect the side surfaces of the first and second panels 100 and 110 from damage. can do.

As described above, as the resin layer 600 is formed by curing the resin material layer 1500 using UV, the resin layer 600 may have a convex shape as shown in FIG. 38. .

Accordingly, in the first direction DR1, the first and second resin layers 600A and 600B protrude further by a predetermined length T1 than the rear substrates 211A and 211B of the first and second panels 100 and 110. It may include a portion to be.

In addition, in the second direction DR1, the first and second resin layers 600A and 600B protrude further by a predetermined length T2 than the front substrates 201A and 201B of the first and second panels 100 and 110. It is also possible to include parts.

In this case, as in the case of FIG. 39, the filter 220 may protrude more than the periphery by a predetermined length T3 in the region overlapping the resin layer 600 in the second direction DR2 by the resin layer 600. Can be.

In addition, the other end of the electrode 1610 of the flexible substrate 1600 may be connected to a connector 1710 disposed on the frame 300 disposed behind the rear substrate 211, as shown in FIG. 41. .

Here, the connector 1710 may be connected to a driving board (not shown). Accordingly, the driving signal generated by the driving board may be supplied to the first electrodes 202 and 203 via the connector 1710 and the flexible substrate 1600.

A part of the flexible substrate 1600 may be covered by the resin layer 600. In other words, the resin layer 600 may include a portion covering a part of the flexible substrate 1600.

In addition, the flexible substrate 1600 in the first direction DR1 may include a portion overlapping the front substrate 201, the seal layer 400, and the rear substrate 211.

On the other hand, the resin layer 600 may be formed around the front substrate 201. For example, as shown in FIG. 43, when the viewer observes the resin layer 600 from the front of the panel, the resin layer 600 is placed at the edge of the front surface of the front substrate 201. It may appear to form.

Meanwhile, the at least one flexible substrate 1600 may be located between two adjacent panels. This will be described with reference to FIG. 44 as follows.

As shown in FIG. 44, the first panel 100 and the second panel 110 may include a second long side LS2 opposed to the first long side LS1 and the first long side LS1. ), A first short side SS1 adjacent to the first long side LS1 and a second long side LS2, and a second short side SS2 opposed to the first short side SS1. can do.

In addition, the second short side SS2 of the first panel 100 and the first short side SS1 of the second panel 110 may be disposed to face each other. In this case, the core area SA may be formed between the second short side SS2 of the first panel 100 and the first short side SS1 of the second panel 110.

In this case, as shown in FIG. 44B, the first flexible substrate 1600A connected to the first panel 100 may be located at the second short side SS2 side of the first panel 110. That is, the first flexible substrate 1600A may be located between the first panel 100 and the second panel 110.
