1 to 3 are views for explaining the structure and driving method of the plasma display panel.

The plasma display panel may implement an image in a frame including a plurality of subfields.

In detail, as illustrated in FIG. 1, the plasma display panel includes a rear substrate 211 on which a plurality of second electrodes 213 and X intersect the plurality of first electrodes 202 (Y) and 203 (Z). can do.

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

On the front substrate 201 where the scan electrodes 202 and Y and the sustain electrodes 203 and Z are formed, the discharge currents of the scan electrodes 202 and Y and the sustain electrodes 203 and Z are limited and the scan electrodes 202 and Y are restricted. ) And an upper dielectric layer 204 may be arranged to insulate between the sustain electrodes 203 and Z.

A protective layer 205 may be formed on the front substrate 201 on which 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.

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).

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.

The partition 212 may include a first partition 212b and a second partition 212a, and a height of the first partition 212b and a height of the second partition 212a may be different from each other.

In the discharge cell, the address electrode 213 may cross the scan electrode 202 and the sustain electrode 203. That is, the discharge cell is formed at the point where the address electrode 213 crosses the scan electrode 202 and the sustain electrode 203.

A predetermined discharge gas may be filled in the discharge cell partitioned by the partition wall 212.

In addition, a phosphor layer 214 that emits visible light for image display may be formed in the discharge cells partitioned by the partition wall 212. 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.

In addition, the address electrode 213 formed on the rear substrate 211 may have substantially the same width or thickness, but the width or thickness inside the discharge cell may be different from the width or thickness 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, discharge may occur in the discharge cell. As such, when discharge is generated in the discharge cell, ultraviolet rays may be generated by the discharge gas filled in the discharge cell, and the ultraviolet rays may be irradiated onto the phosphor particles of the phosphor layer 214. Then, a predetermined image may be displayed on the screen of the plasma display panel 100 by the phosphor particles irradiated with ultraviolet rays to emit visible light.

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

Referring to FIG. 2, a frame for implementing gray levels of an image may include a plurality of subfields SF1 to SF8.

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. 2, 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. 2, 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. 2, 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 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.

A driving waveform for driving the plasma display panel is as follows.

Referring to FIG. 3, 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.

Thin enough Therefore, hereinafter, it will be described on the assumption that the upper dielectric layer 204 and the seal layer 400 are in contact with each other.

In addition, as shown in FIG. 4, one side of the panel may be sealed by a glass material as indicated by A. FIG. In other words, as in area A of FIG. 4, the glass layer 600 may be disposed on the side surfaces of the seal layer 400, the upper dielectric layer 204, the lower dielectric layer 215, and the address electrode 213. In other words, the glass layer 600 may be disposed on the surfaces of the seal layer 400, the upper dielectric layer 204, the lower dielectric layer 215, and the address electrode 213 in a direction from the one side of the panel toward the outside of the panel.

As described above, the glass layer 600 is disposed at one end of the address electrode 213, and the other end thereof may be exposed to the outside of the seal layer 400. The same applies to the scan electrode 202 and the sustain electrode 203.

Looking at the manufacturing method of the plasma display panel according to the present invention.

Looking at Figure 5, as shown in (a), it is possible to form a seal layer 400 on the edge of the back substrate 211.

Here, although only the case of forming the seal layer 400 on the back substrate 211 is shown, it is possible to form the seal layer 400 on at least one of the front substrate 201 and the back substrate 211.

Thereafter, as illustrated in FIG. 5B, the front substrate 201 and the rear substrate 211 may be bonded to each other.

Thereafter, as illustrated in FIG. 5C, the exhaust tip 220 may be connected to the exhaust hole 200, and the exhaust pump 230 may be connected to the exhaust tip 220. In addition, by using the exhaust pump 230, the impurity gas remaining in the discharge space between the front substrate 201 and the rear substrate 211 can be discharged to the outside, and argon (Ar), neon (Ne), xenon Discharge gas such as (Xe) can be injected into the discharge space.

Thereafter, as illustrated in FIG. 6A, the front substrate 201 and the rear substrate 211 of the outer portion of the seal layer 400 may be cut according to a predetermined cutting line CL. Preferably, when cutting the outer portion of the seal layer 400, a portion of the seal layer 400 may also be cut together. In this case, the size of the bezel area may be reduced by reducing the size of the portion where the image is not displayed.

In addition, it may be preferable to use heat or a laser beam in the cutting process of FIG. That is, a portion of the front substrate 201, the rear substrate 211 and the seal layer 400 is cut at one side of the panel by irradiating heat or a laser beam.

For example, as shown in FIG. 7, the panel may be cut in the lateral direction using a cutting device 700 that emits a hot wire or a laser beam. B is indicated in the moving direction of the cutting device 700.

Alternatively, as shown in FIG. 8, the cutting device 700 is used to cut in the direction from the front substrate 201 to the rear substrate 211 or to the front substrate 201 from the rear substrate 211 as opposed to FIG. 8.

After the injection, the outer portion of the seal layer 400 may be cut using an ultrasonic cutter or a diamond cutter.

In addition, it is possible to perform the grinding (Grinding) process to trim the cut surface after the cutting process.

In the plasma display panel manufactured in this manner, as shown in FIG. 9A, a crack 900 may occur on the front substrate 201 and the rear substrate 211 due to the physical properties of the glass material. Such a crack 900 may cause a decrease in the strength of the front substrate 201 and the rear substrate 211 to deteriorate structural reliability.

On the other hand, when the front substrate 201 and the rear substrate 211 is cut using heat or a laser beam as in the present invention, it is possible to prevent the occurrence of cracks as shown in Figure 9 (b), accordingly The fall of the strength of a panel can be prevented.

In addition, when the heat or laser beam is used, a portion of the front substrate 201 and the rear substrate 211 may be cut without generating cracks as shown in FIG. 9 (b). It is possible to increase the size of the cut portion compared to the case. Accordingly, the size of the bezel area can be further reduced.

The flexible circuit substrate 420 may electrically connect the driving board 410 and the scan electrodes or the sustain electrodes 202 and 203. The flexible substrate 420 may be flexible to bend, and may include a predetermined circuit pattern. The flexible substrate 420 may include a tape carrier package (TCP), a flexible printed circuit (FPC), or the like.

One side of the flexible board 420 may be connected to the connector 411 of the driving board 410, and the other side of the flexible board 420 may be the scan pad electrode 202P or the sustain electrode (the scan electrode 202). It may be electrically connected to the sustain pad electrode 203P of 203. Accordingly, the driving board 420 and the scan electrode 202 or the sustain electrode 203 may be electrically connected.

In addition, the first portion of the first width T1 and the third portion of the third width T3 may be alternately disposed.

As such, when the first portion of the first width T1 and the third portion of the third width T3 are alternately arranged, even when the scan pad electrode 202P and the sustain pad electrode 203P are disposed adjacent to each other. It is possible to more easily prevent the scan pad electrode 202P and the sustain pad electrode 203P from being electrically connected. In addition, the scan driver and the scan pad electrode 202P may be electrically connected more easily, and the sustain driver and the sustain pad electrode 203P may be electrically connected more easily.
