That is, in the present invention, if the metal layer is formed on the side of the electrode, and the flexible substrate 500 and the electrode are electrically connected using the metal layer, any type of display panel may be applied.

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 that are parallel to each other, and sustain electrodes 203 and Z, and the second electrode 211 may be referred to as an address electrode 213. .

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 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.

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.

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 that generates red light, a second phosphor layer that generates blue light, and a third phosphor layer that generates 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 because the phosphor particles irradiated with ultraviolet rays emit visible light.

Meanwhile, the electromagnetic shielding layer 250 is further included on the front surface of the plasma display panel. The electromagnetic shielding layer 250 serves to prevent electro-magnetic interference (EMI) by blocking electromagnetic waves generated by the electromagnetic wave generated by the discharge in the discharge cell or the driving signal supplied to the plasma display panel. .

Therefore, the electromagnetic shielding layer 250 is formed of an electrically conductive material to block electromagnetic waves generated in the front direction of the front substrate 201, and may be formed in a mesh form or a thin film form according to its shape.

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.

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. 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.

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 213 (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 213.

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.

Accordingly, the flexible substrate 500 may be located on the side of the plasma display panel.

As such, when the flexible substrate 500 is electrically connected to the short side surface of the panel electrode 213, the size of the portion W1 where an image is not displayed in the plasma display panel may be reduced. That is, the size of the bezel area, which is an area where no image is displayed, may be reduced.

The conductive adhesive layer 430 illustrated in FIG. 4B shows structural stability at the connection portion between the flexible substrate 500 and the panel electrode 213 and the connection portion between the flexible substrate 500 and the electromagnetic shielding layer 250.

Here, the metal that can be applied to the organometallic compound may be a material having high electrical conductivity, such as silver (Ag), gold (Au), palladium (Pd), and the like.

In addition, the organometallic compound may include a material such as an organic solvent and a binder in addition to the metal material.

Examples of organometallic compounds applicable to the present invention include metal compounds including metal alkoxides, metal acetates and metal acid compounds, ethylene glycol, propanediol and derivatives thereof, butanediol and derivatives thereof, pentanediol and its Diols containing derivatives and hexanol are mixed or reacted in a constant molar ratio, and solid and liquid organic metals prepared by using trimethyl phosphate (TMP), triethyl phosphate (TEP) and triphenyl phosphate (TPP) as additives Compound.

The organometallic layer 700 as shown in FIGS. 6C and 6D may be formed using the organometallic compound as described above.

Thereafter, as illustrated in FIG. 6E, the flexible substrate 500 may be disposed on the organic metal layer 700, and pressure may be applied to the flexible substrate 500 at a predetermined temperature.

Here, when the ambient temperature rises above the critical temperature, the chemical bond between the metal material and the carbon is broken in the organic metal compound constituting the organic metal layer 700, and the metal material has a short side surface of the panel electrode 213 and the flexible substrate 500. ) And between the short side surface of the electromagnetic shielding layer 250 and the flexible substrate 500. Accordingly, the conductive adhesive layer 430 is formed between the flexible substrate 500 and the panel electrode 213, and the conductive adhesive layer is formed between the flexible substrate 500 and the electromagnetic shielding layer 250, thereby forming the conductive adhesive layer 430 of FIG. 6F. As described above, the flexible substrate 500, the panel electrode 213, the flexible substrate 500, and the electromagnetic shielding layer 250 may be electrically connected to each other.

7 to 11, various examples of the flexible substrate 500 according to the present invention will be described in more detail.

As shown in FIG. 7A, the flexible substrate 500 according to the present invention includes a base substrate 530, a plurality of connection electrodes 510, and a ground electrode 520.

Here, the base substrate 530 includes a panel connection part 531, a reduction part 533, and a connector connection part 535.

In the panel connection portion 531, a ground electrode 520 is formed in parallel with a plurality of conductive connection electrodes 510 and a plurality of connection electrodes 510. Here, the ground electrode 520 may be formed outside the plurality of connection electrodes 510.

The reduction part 533 is formed by extending the plurality of connection electrodes 510 from the panel connection part 531 so that the distance between the edge connection electrodes disposed at both outermost sides of the plurality of connection electrodes 510 is gradually reduced. In addition, the ground electrode 520 may be formed to extend from the panel connection part 531 in parallel to the outside of the plurality of connection electrodes 510.

In the connector connection portion 535, the plurality of connection electrodes 510 are formed to extend in parallel with each other from the reduction part 533, and the ground electrode 520 extends from the reduction part 533 so as to be connected to the plurality of connection electrodes 510. It can be formed side by side.

Here, forming the connection electrode 510 connected to the panel electrode 213 and the ground electrode 520 connected to the electromagnetic shielding layer 250 together on the flexible substrate 500 may form the flexible substrate 500 in plasma. When the panel electrode 213 is connected to the connection electrode 510 in the process of connecting to the short side of the display panel, the electromagnetic shielding layer 250 is grounded by connecting the ground electrode 520 to the electromagnetic shielding layer 250 together. In addition to reducing the additional process of GND, the cost can be reduced by making the ground (GND) through the flexible substrate 500 without forming a separate additional conductive layer for grounding the electromagnetic shielding layer 250. It has an effect.

On the other hand, the ground electrode 520 formed in the panel connector 531 is formed to protrude more than the plurality of connection electrodes 510 formed in the panel connector 531. This is because the panel electrodes 213 and the electromagnetic shielding layer 250 are formed at different positions in the plasma display panel as shown in FIGS. 4C and 6F.

In more detail, when the panel electrode 213 is the address electrode 213, the panel electrode 213 is formed on the rear substrate, and the electromagnetic shielding layer 250 is formed on the front substrate 201. In this case, the ground electrode 520 of the flexible substrate 500 connecting with the electromagnetic shielding layer 250 is formed to protrude more than the connection electrode 510 of the flexible substrate 500 connected with the panel electrode 213. When connecting to the electromagnetic shielding layer 250 and the ground electrode 520 it can be more easily connected. Therefore, the length of the ground electrode 520 formed on the panel connection part 531 may also be longer than the length of each of the plurality of connection electrodes 510 formed on the panel connection part 531 as shown in FIG. 7B. .

The ground electrode 520 may be positioned at the outer side of the plurality of connection electrodes 510 more than the edge connection electrode 510 disposed at the outermost side. As shown in FIG. 6B, when the outer portion of the plasma display panel is ground and cut, the plurality of panel electrodes 213 that are gradually narrowed in the outer portion of the plasma display panel are formed on one flexible substrate. This is to connect the connecting electrodes 510 and to connect the ground electrode 520 to the electromagnetic shielding layer 250 through the panel electrodes 213a and 213b having a wide width.

In addition, as illustrated in FIGS. 7B and 7C, the length LG1 of the ground electrode 520 formed in the panel connection part 531 is equal to the length of the ground electrode 520 formed in the connector connection part 535. Longer than LG3).

In addition, as shown in FIGS. 7B and 7C, the width of the ground electrode 520 formed in the panel connection part 531 is the ground electrode 520 formed in the panel connection part 531 or the connector connection part 535. You can make it larger than the width of). In this way, the ground electrode 520 formed in the panel connection portion 531 has a large width WG1 so that the area of the portion connected to the electromagnetic shielding layer 250 is relatively large, thereby reducing the sheet resistance, and the panel connection portion 531. ) Or the ground electrode 520 formed at the connector connection portion 535 is to relatively reduce the width (WG2, WG3) in order to reduce the size of the flexible substrate. In addition, the ground electrode 520 formed on the connector connection part 535 does not need to increase the width WG3 because the widths of the connection terminals of the connector are equal to each other when the connector and the connector are fastened.

In addition, the width WG1 of the ground electrode 520 formed in the panel connector 531 may be the width of the connection electrode 510 formed in the panel connector 531 or the width of the connection electrode 510 formed in the connector connector 535. It can be made larger than WC3). By doing so, the width WG1 of the ground electrode 520 connected to the electromagnetic shielding layer 250 in the panel connection portion 531 is relatively larger, so that the larger area of the ground electrode 520 becomes the electromagnetic shielding layer 250. This is because the contact resistance between the electromagnetic shielding layer 250 and the ground electrode 520 can be minimized.

In addition, the width WG3 of the ground electrode 520 formed in the connector connector 535 may be the same as the width WC3 of each of the plurality of connection electrodes 510 formed in the connector connector 535. In this way, the connector connecting portion 535 of the flexible substrate 500 on which the connecting electrode 510 and the ground electrode 520 are formed may be naturally fastened to the connector having the same width as each terminal.

In addition, the gap DCG1 between the edge connection electrode 510 and the ground electrode 520 in the panel connection part 531 is larger than the gap DC1 between the plurality of connection electrodes 510 formed in the panel connection part 531. Can be formed. In this manner, the ground electrode 520 and the connection electrode 510 can be sufficiently spaced apart, and the connection electrode 510 can be prevented from being shorted by the ground electrode 520.

In addition, the gap DCG3 between the edge connection electrode 510 and the ground electrode 520 in the connector connection part 535 is greater than the gap between the plurality of connection electrodes 510 formed in the connector connection part 535 (DC3). Can be. By doing in this way, the ground electrode 520 and the connection electrode 510 can be easily distinguished by the eyes at the connector connection part 535, and the work can be easily and accurately connected when connecting the connector of the connector and the flexible board 500 to each other. There is an effect that can lead to.

In addition, as shown in FIG. 7A, a flexible integrated circuit (IC) may be mounted on the flexible substrate 500. Therefore, the data signal supplied to each of the panel electrodes 213 can be controlled through the data IC.

In FIG. 7, the data IC is mounted on the flexible substrate 500 as an example. However, when the flexible substrate 500 is connected to the scan electrode 202 or the sustain electrode 203, the data IC is omitted. Can be.

In addition, in FIG. 7, only one base substrate 530 of the flexible substrate 500 is illustrated as an example. However, as illustrated in FIG. 8, a plurality of base substrates 530 of the flexible substrate 500 may be used. It is possible.

Specifically, FIG. 8A illustrates a plurality of connection electrodes 510 formed on the first base substrate 530a and the second base substrate 530b electrically separated from each other in the flexible substrate 500. 8 (b) shows a state in which the plurality of connection electrodes 510 formed on the first base substrate 530a and the second base substrate 530b are electrically connected to each other.

As shown in FIGS. 8A and 8B, the flexible substrate 500 includes a first base substrate 530a and a second base substrate 530b, and includes a first base substrate 530a and a second substrate. In the base substrate 530b, a plurality of conductive connection electrodes 510 and a ground electrode 520 may be formed outside the plurality of connection electrodes 510.

More specifically, in the flexible substrate 500 according to the present invention, the first base substrate 530a and the second base substrate 530b having the plurality of connection electrodes 510 are formed as shown in FIG. ), Wherein the first base substrate 530a includes a first panel connector 531a, a first reduction part 533a, and a first substrate connector 535a, and the second base substrate 530b The second substrate connector 531b, the second reducer 533b, and the connector connector 535b may be included.

As shown in FIG. 8A, the flexible substrate 500 includes a plurality of connection electrodes 510 of the first substrate connection part 535a and a plurality of connection electrodes 510 of the second substrate connection part 531b. Are overlapped and electrically connected to each other, and the first substrate connection part 535a of the first base substrate 530a and the second substrate connection part 531b of the second base substrate 530b may be formed to be separated from each other.

In this case, the thickness d1 ′ of the portion in which the connecting electrodes 510 of the first and second substrate connecting portions 535a and 531b overlap each other is defined as the thickness of the portion in which the connecting electrodes 510 do not overlap each other. It can be formed thinner than d2). Here, in FIG. 8D, an example is directly connected between the plurality of connection electrodes 510 of the first substrate connection part 535a and the plurality of connection electrodes 510 of the second substrate connection part 531b without another adhesive layer. Although illustrated as, alternatively, it may be electrically connected through another adhesive layer.

9 illustrates an example in which a plurality of flexible substrates 500 according to the present invention are attached to the side of the display panel.

As shown in FIG. 9A, a plurality of flexible substrates 500 may be attached perpendicularly to the X direction in which a short side surface of the address electrode 213 of the display panel is formed, and the scan electrode or the sustain of the display panel may be attached. Short sides of the electrodes 202 and 203 may be attached perpendicularly to the Y direction in which they are formed. In this case, a data IC 570 is formed on the flexible substrate 500 attached perpendicularly to the X direction of the display panel, so that the data signal supplied to each address electrode 213 in the address period of the subfield is formed. You can control the input. In addition, the data IC 570 may not be formed on the flexible substrate 500 attached to the Y direction of the display panel.

Here, the gap DC1 between the plurality of connection electrodes 510 formed in the panel connection part 531 is equal to the distance DP between the end surfaces of the plurality of panel electrodes 213 as shown in the drawing, and the panel connection part ( The width WC1 of each of the plurality of connection electrodes 510 formed on the plurality of connection electrodes 510 may be the same as the width WP of each of the short side surfaces of the panel electrodes 213, but differently between the connection electrodes 510. The gap DC1 is narrower than the gap DP between the short side surfaces of the panel electrodes 213, and the width WC1 of each of the plurality of connection electrodes 510 formed in the panel connection part 531a has a plurality of panel electrodes 213. It may be larger than the width WP of each of the short sides.

By doing so, when connecting the connecting electrode 510 to the short side of the panel electrode 213, even if there is a slight alignment error, the short side of the panel electrode 213 is located within the width of the connecting electrode 510. By doing so, there is an effect that can minimize the defect.

In addition, the width WG1 of the ground electrode 520 formed at the panel connection portion 531 is the largest of the intervals between the plurality of panel electrodes 213, as shown in FIGS. 9B and 9C. It can be formed smaller than the interval (MDP). In this way, a structure extending from the side surface of the plasma display panel to the short side surface of the panel electrode 213 to be electrically connected to the electromagnetic shielding layer 250 can be formed.

FIG. 10 is a diagram for describing various ways in which the flexible substrate 500 according to the present invention may be connected to a short side of a display panel.

More specifically, as shown in FIGS. 12A and 12B, a portion of the panel electrode 213 protrudes toward the side of the display panel and is bent toward the rear substrate 211 to partially face the panel electrode 213. The connection electrode 510 is directly connected to a portion of the electromagnetic shielding layer 250 in a state in which a portion of the electromagnetic shielding layer 250 protrudes toward the side of the display panel and is bent toward the short side of the front substrate 201. Ground electrode 520 may be directly connected to. In addition, although not shown, the connection electrode 510 may be connected to a part of the side of the panel electrode 213 while a part of the panel electrode 213 protrudes toward the side of the display panel to be bent toward the front substrate 201. will be. In this case, the panel connection part 531 is not parallel to the short side surface of the panel electrode 213 or the short side surface of the electromagnetic shielding layer 250, and the short side surface of the front substrate 201 and the short side surface of the rear substrate 211. It is placed side by side.

In this case, the surface contact of the panel electrode 213 and the connection electrode 510 and the surface of the electromagnetic shielding layer 250 and the ground electrode 520 are relatively increased, so that the sheet resistance of the contact surface may be relatively reduced. It is effective.

In addition, as shown in (c) and (d) of FIG. 10, a portion of the panel electrode 213 and a portion of the electromagnetic shielding layer 250 protrude to the side of the display panel to further reduce the sheet resistance of the contact surface. After forming the conductive adhesive layer such as ACA or ACF described above on the bent portion of the panel electrode 213 and the bent portion of the electromagnetic shielding layer 250, the conductive adhesive layer is formed to connect with the panel electrode 213. The electrode 510 may be electrically connected to each other, and the electromagnetic shielding layer 250 and the ground electrode 520 may be electrically connected to each other.
