FIG. 2 is an internal block diagram of the controller shown in FIG. 11.

Referring to FIG. 2, the controller 170Q may include a demultiplexer 310Q, an image processor 320Q, an OSD generator 340Q, a mixer 350Q, a frame rate converter 355Q, and a formatter 360Q. It may include. In addition, the apparatus may further include a voice processor (not shown) and a data processor (not shown).

The demultiplexer 310Q demultiplexes the input stream. For example, when an MPEG-2 TS is input, it may be demultiplexed and separated into video, audio, and data signals, respectively. Here, the stream signal input to the demultiplexer 310Q may be a stream signal output from the tuner 110Q, the demodulator 120Q, or the external device interface unit 135Q.

The image processor 320Q may perform image processing of the demultiplexed image signal. To this end, the image processor 320Q may include an image decoder 325Q and a scaler 335Q.

The video decoder 325Q decodes the demultiplexed video signal, and the scaler 335Q performs scaling to output the resolution of the decoded video signal on the display unit 180Q.

The video decoder 325Q may include decoders of various standards.

For example, when the demultiplexed video signal is an encoded video signal of MPEG-2 standard, it may be decoded by an MPEG-2 decoder.

Also, for example, when the demultiplexed video signal is a digital video broadcasting (DMB) scheme or an encoded video signal of H.264 standard according to DVB-H, it may be decoded by an H.264 decoder.

On the other hand, the video signal decoded by the image processor 320Q is input to the mixer 350Q.

The OSD generator 340Q generates an OSD signal according to a user input or itself. For example, based on a control signal from the user input interface unit 150Q, a signal for displaying various types of information on a screen of the display unit 180Q as a graphic or text may be generated. The generated OSD signal may include various data such as a user interface screen, various menu screens, widgets, and icons of the broadcast signal receiver 100Q.

For example, the OSD generator 340Q may generate a signal for displaying broadcast information based on subtitles or EPGs of a broadcast video. Alternatively, the OSD generator 340Q may generate a cursor according to a user's input.

The mixer 350Q may mix the OSD signal generated by the OSD generator 340Q and the decoded image signal processed by the image processor 220Q. The mixed signal is provided to the formatter 360Q. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image. For example, the cursor generated by the OSD generator 340Q may be displayed on the display 180Q.

The frame rate converter (FRC) 355Q may convert a frame rate of an input video. For example, a 60Hz frame rate is converted to 120Hz or 240Hz. When converting a frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame or insert a third frame predicted from the first frame and the second frame between the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or three predicted frames. On the other hand, it is also possible to maintain the input frame rate without additional conversion.

The formatter 360Q receives the output signal of the frame rate converter 355Q, changes the format of the signal to be suitable for the display unit 180Q, and outputs the signal. For example, the R, G, B data signals may be output, and the R, G, B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.

The voice processor (not shown) in the controller 170Q may perform voice processing of the demultiplexed voice signal. To this end, the voice processing unit (not shown) may include various decoders.

The speech processing unit (not shown) in the controller 170Q may decode the demultiplexed speech signal when the speech signal is encoded. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, or an MPEG 4 decoder, or an AAC decoder, or an AC-3 decoder.

In addition, the voice processing unit (not shown) in the controller 170Q may process base, treble, volume control, and the like.

The data processor (not shown) in the controller 170Q may perform data processing of the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, it may be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme, and may include DVB-Service Information (DVB-SI) in the case of the DVB scheme. .

The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, that is, the header (4 bytes) of the MPEG-2 TS.

In addition, the remote control apparatus 200Q may include an IR module 223Q capable of transmitting and receiving a signal with the broadcast signal receiver 100Q according to the IR communication standard.

In the present embodiment, the remote control device 200Q transmits a signal containing information on the movement of the remote control device 200Q and the like to the broadcast signal receiver 100Q through the RF module 221Q.

In addition, the remote control apparatus 200Q may receive a signal transmitted from the broadcast signal receiver 100Q through the RF module 221Q. In addition, the remote control apparatus 200Q may transmit a command regarding power on / off, channel change, volume change, etc. to the broadcast signal receiver 100Q through the IR module 223Q as necessary.

The user input unit 235Q may include a keypad, a button, a touch pad, and the like. The user may input a command related to the broadcast signal receiver 100Q to the remote controller 200Q by manipulating the user input unit 235Q. When the user input unit 235Q includes a hard key button, the user may input a command related to the broadcast signal receiver 100Q to the remote control apparatus 200Q through a push operation of the hard key button. When the user input unit 235Q includes a touch screen, the user may input a command related to the broadcast signal receiver 100Q to the remote controller 200Q by touching a soft key of the touch screen. In addition, the user input unit 235Q may include various kinds of input means that a user can operate, such as a scroll key or a jog key, and the present embodiment does not limit the scope of the present invention.

The sensor unit 240Q may include an optical sensor that senses light generated at a predetermined position of the display unit 180Q.

In this case, the wireless communication unit 225Q may transmit information about the light detected by the sensor unit 240Q to the user input interface unit 150Q of the broadcast signal receiver under the control of the controller 280Q. For example, the wireless communication unit 225Q may transmit information about a detection time point of light detected by the sensor unit 240Q to the user input interface unit 150Q.

In addition, the sensor unit 240Q may further include a gyro sensor 241Q or an acceleration sensor 243Q.

The gyro sensor 241Q may sense information about the movement of the remote controller 200Q.

For example, the gyro sensor 241Q may sense information about an operation of the remote controller 200Q based on the x, y, and z axes. The acceleration sensor 243Q may sense information about a moving speed of the remote control device 200Q. On the other hand, the distance measuring sensor may be further provided, whereby the distance to the display unit 180Q may be sensed.

The power supply unit 260Q supplies power to the remote control device 200Q. The power supply unit 260Q may reduce power waste by stopping power supply when the remote controller 200Q does not move for a predetermined time. The power supply unit 260Q may resume power supply when a predetermined key provided in the remote control apparatus 200Q is operated.

The storage unit 270Q may store various types of programs and application data required for controlling or operating the remote control apparatus 200Q. If the remote control device 200Q transmits and receives a signal wirelessly through the broadcast signal receiver 100Q and the RF module 221Q, the remote control device 200Q and the broadcast signal receiver 100Q transmit signals through a predetermined frequency band. Send and receive The control unit 280Q of the remote control apparatus 200Q stores information on a frequency band or the like that can transmit and receive a signal wirelessly with the broadcast signal receiver 100Q paired with the remote control apparatus 200Q in the storage unit 270Q. Reference may be made.

The controller 280Q controls various items related to the control of the remote controller 200Q. The control unit 280Q receives a signal corresponding to a predetermined key operation of the user input unit 235Q or a signal corresponding to the movement of the remote control apparatus 200Q sensed by the sensor unit 240Q through the wireless communication unit 225Q. Can be sent to (100Q).

An operation in the touch mode will now be described with reference to FIG. 4.

Referring to FIG. 5, it may be determined whether the touch mode is set (500Q). That is, it is determined whether the broadcast signal receiver 100Q is set to the touch mode according to the user's input.

Here, the user may set the broadcast signal receiver 100Q to the touch mode using the remote control device 200Q.

As a result of the determination, when the touch mode is set to the touch mode, the remote controller 200Q may detect the light generated by the display unit 180Q (510Q). For example, the sensor unit 240Q of the remote control apparatus 200Q may sense light.

Thereafter, the remote controller 200Q may transmit information 520Q on the light detected by the sensor unit 240. For example, the wireless communication unit 225Q of the remote control apparatus 200Q may transmit information about light detected by the sensor unit 240 to the user input interface unit 150Q. Here, the transmitted information may include detection time information of light detected by the center unit 240Q.

Then, in the broadcast signal receiver 100Q, the controller 170Q may calculate / acquire the position information of the touch based on the information received from the user input interface unit 150Q. For example, in the broadcast signal receiver 100Q, the controller 170Q compares the information with the driving information of the display unit 180Q at the time of detecting the light from the user input interface unit 150Q, so that the sensor unit 240Q displays the display unit ( It is possible to detect the pixel Pixel of the display unit 180Q that emits light when the light of the 180Q is sensed.

Subsequently, according to the control of the controller 170Q, a predetermined cursor may be displayed on the screen of the display unit 180Q, that is, the position of the point indicated by the sensor unit 240 (530Q). It is possible to use the OSD signal when displaying the cursor.

For example, as shown in FIG. 5, the cursor 205Q may be displayed at a predetermined position of the display unit 180Q of the broadcast signal receiver 100. Here, the point where the cursor 205Q is located may be a position indicated by the remote control device 200Q.

Thereafter, whether the touch of a predetermined object is made at the point where the cursor is located may be determined (540Q). Alternatively, it is also possible to determine whether an instruction to execute a predetermined instruction is issued.

As a result of the determination, when a touch is made, it is possible to select a corresponding object or execute a corresponding command (550Q).

For example, as shown in (A) and (B) of FIG. 6, the remote control apparatus 200Q of the remote control apparatus 200Q is displayed in a state where the cursor 205Q is displayed at a predetermined position of the display unit 180Q of the broadcast signal receiver 100. When the position is moved, the position of the cursor 205Q may also be moved on the screen of the display unit 180Q.

For example, as in the case of FIG. 6B, when the remote controller 200Q is horizontally moved while the cursor 205Q is displayed at a predetermined position of the display unit 180Q, the display unit 180Q is used. The position of the cursor 205Q can also be moved horizontally on the screen.

As such, in the touch mode, the display unit 180Q may display a cursor 205Q indicating a touch position, and move the position of the cursor 205Q or move the cursor 205Q by using the remote controller 200Q. It is possible to select an object indicated by or to execute a predetermined command.

Accordingly, as shown in FIG. 7A, the touch mode may be a mode in which the cursor 205Q is displayed on the display unit 180Q.

In addition, in the normal mode other than the touch mode, the cursor 205Q may not be displayed on the display unit 180Q as in the case of FIG. 7B.

Meanwhile, the display unit 180Q of the broadcast signal receiver of the present invention may be a plasma display panel (PDP). Since the plasma display panel can sequentially supply scan signals to the scan electrodes (Y) disposed on the front substrate and sequentially supply data signals to the address electrodes (X) disposed on the rear substrate, the plasma display panel can be horizontally and vertically touched. It may be easy to detect the location.

Hereinafter, a plasma display apparatus and a multi-plasma display apparatus applied to the broadcast signal receiver of the present invention will be described.

8 to 10 are views for explaining a structure and a driving method of the plasma display panel. Hereinafter, the description of the parts described in detail above will be omitted.

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

In detail, as illustrated in FIG. 8, 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.

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.

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 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 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. 9, 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. 9, 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 value 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. 9, 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. 9, 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.

Here, the selective erasing subfield is a subfield that turns off the discharge cells supplied with the data signal Data to the address electrodes in the address period in the sustain period after the address period.

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

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

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

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

Referring to FIG. 10, 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) 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 SP falling 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 DP 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 Zb 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.

FIG. 10 illustrates an example of a driving waveform used in a general mode other than the touch mode. In the touch mode, at least one of the plurality of subfields of the frame may be set as the scan subfield for the touch. This will be described in detail below.

11 to 70 are views for explaining the operation in the touch mode of the plasma display device according to the present invention in detail. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 11, at least one of a plurality of subfields constituting one frame may be set as a scan subfield in the touch mode. For example, a first subfield and a second subfield among a plurality of subfields of a frame may be used as a scan subfield for detecting a touch position. In addition, the remaining subfields except the scan subfield among the plurality of subfields of the frame may be normal subfields (Normal SF).

In addition, in the normal mode other than the touch mode, the frame does not include the scan subfield, and all subfields included in the frame may be the general subfield.

In other words, as shown in FIG. 5, when the cursor 205Q is displayed on the display unit 180Q, at least one subfield among the plurality of subfields of the frame may be set as a scan subfield.

Referring to FIG. 12, the scan subfield may include a vertical scan subfield VSSF for detecting a vertical position of the touch position and a horizontal scan subfield HSSF for detecting a horizontal position of the touch position.

For example, in the touch mode, the first subfield of the plurality of subfields of the frame may be a vertical scan subfield, and the second subfield may be a horizontal scan subfield.

As such, the vertical scan subfield and the horizontal scan subfield may be continuously arranged in one frame.

Here, only the case where the vertical scan subfield is disposed ahead of the horizontal scan subfield in one frame is illustrated, but it may be possible when the horizontal scan subfield is disposed before the vertical scan subfield. Hereinafter, a case in which the vertical scan subfield is disposed ahead of the horizontal scan subfield will be described as an example.

In the reset period of the vertical scan subfield (hereinafter referred to as scan reset period SRP), the first scan reset signal SRS1 and the second scan reset signal SRS2 may be supplied to the scan electrode Y.

Here, the first scan reset signal SRS1 includes a first scan ramp signal SRU1 and a second scan ramp lamp SRU2 in which the voltage gradually increases. A scan up ramp signal SRU and a first scan down ramp signal SRD1 gradually decreasing in voltage and a second scan down ramp signal SRD2 The falling lamp signal SRD may be included.

The second scan reset signal SRS2 includes a third scan ramp-up signal SRU3 for gradually increasing the voltage and a third scan ramp-down signal for gradually decreasing the voltage. SRD3).

For example, in the first scan setup period SSU1 of the scan reset period SRP, the first scan up ramp signal SRU1 is supplied to the scan electrodes, and then the second scan up ramp signal SRU2 is supplied to the scan electrodes. Can be supplied. In the first scan set-down period SSD1 after the first scan setup period SSU1, the first scan down ramp signal SRD1 and the second scan down ramp signal SRD2 may be sequentially supplied to the scan electrodes.

Here, the slope of the first scan rising ramp signal SRU1, that is, the rate of change in voltage per hour, may be greater than the rate of change in voltage per hour of the second scan rising ramp signal SRU2. In addition, an hourly voltage change rate of the first scan down ramp signal SRD1 may be greater than an hourly voltage change rate of the second scan down ramp signal SRD2.

When the first and second scan up ramp signals are supplied to the scan electrodes, a weak dark discharge, that is, a setup discharge occurs in the discharge cell by the rise 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 first and second scan down ramp signals are supplied to the scan electrodes, 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 first scan set-down period SSD1 of the scan reset period SRP, the first scan sustain reference signal Szb1 having the first sustain reference voltage Vz1 may be supplied to the sustain electrode. In this case, the setdown discharge can be stabilized.

In the second scan setup period SSU2 of the scan reset period SRP, the third scan up ramp signal SRU3 is supplied to the scan electrode, and then, in the second scan set-down period SSD2, the third scan down ramp is supplied to the scan electrode. Signal SRD3 may be supplied.

As such, when the third scan up ramp signal SRU3 and the third scan down ramp signal SRD3 are supplied to the scan electrode, the wall charges in the discharge cell may be more uniformly distributed.

Here, the lowest voltage of the first scan reset signal SRS1, that is, the lowest voltage (-Vy1) of the second scan down lamp signal SRD2 is the lowest voltage of the second scan reset signal SRS2, that is, the third scan down lamp. It is possible to be approximately equal to the lowest voltage (-Vy2) of the signal SRD3.

In the address period (hereinafter referred to as the vertical scan address period VSAP) after the scan reset period of the vertical scan subfield VSSF, the lowest voltage (−) of the second and third scan down ramp signals SRD2 and SRD3 Scan reference voltage Vsc higher than Vy1 and -Vy2 may be supplied to the scan electrode.

In addition, in the vertical scan address period VSAP, the touch scan signal TSP falling from the scan reference voltage Vsc may be supplied to the scan electrode.

Preferably, the touch scan signal TSP may be sequentially supplied to the plurality of scan electrodes Y. Alternatively, the touch scan signal TSP may be supplied to at least two scan electrodes Y at substantially the same time.

Here, the lowest voltage of the touch scan signal TSP is the lowest voltage of the first scan reset signal SRS1, that is, the lowest voltage (-Vy1) of the second scan down ramp signal SRD2 and the second scan reset signal SRS2. It may be preferable that the voltage is lower than the lowest voltage of, i.e., the lowest voltage of the third scan down ramp signal SRD3 (-Vy2).

As such, when the touch scan signal TSP is supplied to the scan electrode Y, the voltages of the address electrode X and the sustain electrode Z may be kept substantially constant.

For example, when the touch scan signal TSP is supplied to the scan electrode Y, the first scan address reference signal Sxb having the first address reference voltage Vx1 is supplied to the address electrode X, The second scan sustain reference signal Szb2 having the second sustain reference voltage Vz2 may be supplied to the sustain electrode Z.

Here, the first address reference voltage Vx1 may be higher than the second sustain reference voltage Vz2. In other words, when the touch scan signal TSP is supplied to the scan electrode Y, the voltage of the address electrode X may be higher than the voltage of the sustain electrode Z.

In addition, the second scan sustain reference signal Szb2 may be partially overlapped with the third scan down ramp signal SRD3.

As such, when the touch scan signal TSP is supplied to the scan electrode Y in the vertical scan address period VSAP, when the voltage of the address electrode X is set higher than the voltage of the sustain electrode Z, the scan electrode Discharge may occur between (Y) and the address electrode (X). Hereinafter, the discharge generated in the vertical scan address period VSAP as described above is referred to as the vertical address discharge.

For example, as in the case of FIG. 13A, the touch scan signal TSP may be sequentially supplied to the plurality of scan electrodes Y1 to Yn, thereby scanning as shown in FIG. 13B. Vertical address discharge may occur between the electrode Y and the address electrode X. FIG.

Here, the vertical address discharge may occur in a plurality of discharge cells arranged side by side in the horizontal direction. For example, when the touch scan signal TSP is supplied to the first scan electrode Y1 among the plurality of scan electrodes Y, discharge may occur in a plurality of discharge cells corresponding to the first scan electrode Y1. When the touch scan signal TSP is supplied to the second scan electrode Y2, discharge may occur in a plurality of discharge cells corresponding to the second scan electrode Y2.

Next, the reset period of the horizontal scan subfield may be omitted.

In the address period of the horizontal scan subfield HSSF (hereinafter referred to as the horizontal scan address period HSAP), the touch data signal TDP may be supplied to the address electrode X. FIG.

Preferably, the touch data signal TDP may be sequentially supplied to the plurality of address electrodes X. Alternatively, the touch data signal TDP may be supplied to at least two address electrodes X at substantially the same time point.

Here, the highest voltage Vx2 of the touch data signal TDP can be approximately equal to the voltage of the data signal supplied to the address electrode X in the address electrode period of the general subfield.

As such, when the touch data signal TDP is supplied to the address electrode X, the voltages of the scan electrode Y and the sustain electrode Z may be kept substantially constant.

For example, when the touch data signal TDP is supplied to the address electrode X, the voltage of the ground level GND may be supplied to the scan electrode Y and the sustain electrode Z, respectively.

As such, when the touch data signal TDP is supplied to the address electrode X in the horizontal scan address period HSAP, when the voltages of the scan electrode Y and the sustain electrode Z are kept constant, the scan electrode ( Discharge may occur between Y) and the address electrode X, or discharge may occur between the sustain electrode Z and the address electrode X. FIG. Hereinafter, the discharge generated in the horizontal scan address period HSAP as described above is referred to as horizontal address discharge.

For example, as in the case of FIG. 14A, the touch data signal TDP may be sequentially supplied to the plurality of address electrodes X1 to Xm, and accordingly, the scan may be performed as shown in FIG. 14B. Horizontal address discharge may occur between the electrode Y and the address electrode X. FIG. Alternatively, although not shown, horizontal address discharge may occur between the sustain electrode Z and the address electrode X. FIG.

Here, the horizontal address discharge may occur in a plurality of discharge cells arranged side by side in the vertical direction. For example, when the touch data signal TDP is supplied to the first address electrode X1 among the plurality of address electrodes X, discharge may occur in a plurality of discharge cells corresponding to the first address electrode X1. When the touch data signal TDP is supplied to the second address electrode X2, discharge may occur in a plurality of discharge cells corresponding to the second address electrode X2.

Meanwhile, the remote controller described above, for example, the remote controller 200Q of FIG. 5, acquires information corresponding to the vertical coordinate of the touch position in the vertical scan address period VSAP, and touches in the horizontal scan address period HSAP. Information corresponding to the horizontal coordinate of the position can be obtained.

For example, when the touch scan signals TSP are sequentially supplied to the plurality of scan electrodes Y1 as in the case of FIG. 13A, discharge may occur sequentially in the vertical direction of the panel.

Here, the remote control device 200Q may sense light generated by the discharge at the time when the discharge occurs at a specific position of the panel. In this case, when the remote control apparatus 200Q compares the information on the time when the light is sensed with the information on the time when the touch scan signal TSP is supplied to the plurality of scan electrodes Y as shown in FIG. 13A. The vertical position on the panel corresponding to the light sensed by the remote control apparatus 200Q may be confirmed.

In addition, when the touch data signals TDP are sequentially supplied to the plurality of address electrodes X1 as in the case of FIG. 14A, discharge may occur sequentially in the horizontal direction of the panel.

Here, the remote control device 200Q may sense light generated by the discharge at the time when the discharge occurs at a specific position of the panel. In this case, when the remote control apparatus 200Q compares the information when the light is sensed with the information about the time when the touch data signal TDP is supplied to the plurality of address electrodes X as shown in FIG. The horizontal position on the panel corresponding to the light sensed by the remote control apparatus 200Q may be confirmed.

For example, as in the case of Fig. 15, assume that the remote control device 200Q indicates a position (Xa, Yb) where the Xa address electrode and the Ya scan electrode intersect on the panel.

In this case, the remote controller 200Q may check the information about the horizontal coordinate of the touch position by detecting light generated by the discharge when the discharge occurs in the plurality of discharge cells corresponding to the Xa address electrode, and the Ya scan electrode. By detecting the light generated by the discharge when the discharge occurs in a plurality of discharge cells corresponding to the information on the vertical coordinate of the touch position can be confirmed.

That is, in the present invention, the vertical left point of the touch position may be acquired by the light generated in the vertical scan address period VSAP, and the horizontal coordinate of the touch position may be obtained by using the light generated in the horizontal scan address period HSAP. .

Meanwhile, as in the case of FIG. 12, at least one of the scan electrode Y and the sustain electrode Z is touched in the scan sustain period SSP between the vertical scan address period VSAP and the horizontal scan address period HSAP. The sustain signal TSUS can be supplied. Preferably, the touch sustain signal TSUS may be alternately supplied to the scan electrode Y and the sustain electrode Z in the scan sustain period SSP.

In other words, after supplying the last touch scan signal TSP in the vertical scan subfield VSSF and before supplying the first touch data signal T in the horizontal scan subfield HSF, the scan electrode Y ) And at least one touch sustain signal TSUS to at least one of the sustain electrode Z.

As such, the touch sustain signal TSUS is supplied to at least one of the scan electrode Y and the sustain electrode Z in the scan sustain period SSP between the vertical scan address period VSAP and the horizontal scan address period HSAP. As a result, a sufficient amount of wall charges can be formed in the discharge cells, thereby making it possible to generate a sufficiently strong horizontal address discharge in the horizontal scan address period (HSAP). Accordingly, it is possible to obtain the touch position more easily and precisely.

Meanwhile, the general subfield may be arranged after the horizontal scan subfield (HSSF). For example, after the horizontal scan subfield HSSF, a general subfield including the reset period RP, the address period AP, and the sustain period SP, for example, the first subfield SF1 may be disposed. . The general subfield has been described in detail with reference to FIG. 10.

Meanwhile, the pre-reset period PRP may be included before the reset period RP of the first subfield SF1. In the pre-reset period PSP, it is possible to supply the falling signal PRD for gradually decreasing the voltage to the scan electrode Y, and to supply the positive signal overlapping the falling signal PRD to the sustain electrode Z. Do. Here, the positive signal can have a predetermined positive voltage Vz3. In other words, after the last touch data signal TDP is supplied from the horizontal scan subfield HSSF, the falling signal PRD is gradually supplied to the scan electrode Y, and the sustain electrode Z is supplied to the sustain electrode Z. It is possible to supply the positive voltage Vz3 overlapping the falling signal PRD. In this case, a sufficient amount of wall charges can be formed in the discharge cell in the pre-reset period PRP of the first general subfield, that is, the first subfield SF1, and accordingly, the first subfield SF1 The reset discharge occurring in the reset period can be stabilized.

In the pre-reset period PRP of the first subfield SF1, the lowest voltage −Vy3 of the falling signal PRD supplied to the scan electrode Y is the lowest voltage − of the second scan falling lamp signal SRD2. Vy1) may be lower than the lowest voltage (−Vy2) of the third scan down ramp signal SRD3.

Referring to FIG. 16, the magnitude of the voltage of the touch scan signal TSP supplied to the scan electrode Y in the vertical scan address period VSAP of the vertical scan subfield VSSF is determined in the address period AP of the general subfield. The voltage of the scan signal SP supplied to the scan electrode may be different.

Preferably, the magnitude of the voltage of the touch scan signal TSP is equal to the scan electrode in the address period AP of the remaining subfields except the vertical scan subfield VSSF and the horizontal scan subfield HSF, that is, the general subfield. Y) may be greater than the magnitude of the voltage of the scan signal SP. In this case, the lowest voltage −V1 of the touch scan signal TSP may be lower than the lowest voltage −V2 of the scan signal SP.

In this case, the intensity of the vertical address discharge can be made stronger.

Referring to FIG. 17, while the touch scan signal TSP is supplied to the plurality of scan electrodes Y in the vertical scan subfield VSSF, the voltage supplied to the address electrode X, that is, the first scan address reference voltage ( Vx1) is higher than the maximum voltage Vd of the data signal DP supplied to the address electrode X in the address period AP of the remaining subfields except the vertical scan subfield and the horizontal scan subfield, that is, the normal subfield. It may be desirable.

In this case, the intensity of the vertical address discharge can be made stronger.

On the other hand, the plurality of touch sustain signals supplied to at least one of the scan electrode Y and the sustain electrode Z in the scan sustain period SSP between the vertical scan address period VSAP and the horizontal scan address period HSAP. TSUS) pulse width may be different from the others. Preferably, the pulse width W2 of the last touch sustain signal TSUS _Last among the plurality of touch sustain signals TSUS may be larger than the pulse width W1 of the remaining touch sustain signals TSUS.

In this case, it is possible to increase the amount of wall charge in the discharge cell, thereby increasing the intensity of the horizontal address discharge occurring in the horizontal scan address period (HSAP).

Alternatively, as in the case of FIG. 19, the last touch sustain signal TSUS _Last among the plurality of touch sustain signals TSUS may include a portion W2a in which the voltage gradually decreases. In other words, the last touch sustain signal TSUS _Last may gradually fall when the voltage falls. In this case, it is possible to further stabilize the horizontal address discharge.

Referring to FIG. 20, the voltage of the touch data signal TDP supplied to the address electrode X in the horizontal scan address period HSAP of the horizontal scan subfield HSSF is determined in the address period AP of the general subfield. The voltage of the data signal DP supplied to the address electrode may be different.

Preferably, the magnitude of the voltage of the touch data signal TDP is the address electrode in the address period AP of the remaining subfields except the vertical scan subfield VSSF and the horizontal scan subfield HSSF, that is, the general subfield. It may be greater than the magnitude of the voltage of the data signal DP supplied to X). In this case, the maximum voltage Vx2 of the touch data signal TDP may be higher than the maximum voltage Vd of the data signal DP.

In this case, the intensity of the horizontal address discharge can be made stronger.

Meanwhile, in the scan sustain period SSP, the voltage in the horizontal scan subfield HSSF of one of the electrodes to which the last touch sustain signal TSUS _Last of the scan electrode Y or the sustain electrode Z is supplied is the other one. It may be lower than the voltage in the horizontal scan subfield (HSSF) of the electrode of.

For example, as shown in FIG. 21, when the last touch sustain signal TSUS _Last is supplied to the scan electrode Y in the scan sustain period SSP, the horizontal scan address period HSAP of the horizontal scan subfield HSSF. The voltage (-V3) of the scan electrode (Y) at may be lower than the voltage (GND) of the sustain electrode (Z).

In this case, the intensity of the horizontal address discharge can be made stronger.

Alternatively, as in the case of FIG. 22, when the last touch sustain signal TSUS _Last is supplied to the scan electrode Y in the scan sustain period SSP, the horizontal scan address period HSAP of the horizontal scan subfield HSSF. The voltage (-V3) of the scan electrode Y at is lower than the voltage at the ground level GND, and the voltage Vz5 of the sustain electrode Z is higher than the voltage at the ground level GND.

In this case, the intensity of the horizontal address discharge can be made stronger.

Or, as in the case of FIG. 23, when the last touch sustain signal TSUS _Last is supplied to the sustain electrode Z in the scan sustain period SSP, as in the case of FIG. 24, the horizontal scan subfield HSSF. A horizontal address discharge may occur between the sustain electrode Z and the address electrode X in the horizontal scan address period H SAP.

In this case, the voltage of the scan electrode Y and the voltage of the sustain electrode Z in the horizontal scan address period HSAP can be substantially the same as the voltage of the ground level GND.

Alternatively, as in the case of FIG. 25, when the last touch sustain signal TSUS _Last is supplied to the sustain electrode Z in the scan sustain period SSP, the voltage of the sustain electrode Z in the horizontal scan address period HSAP. It is possible that Vz6 is lower than the voltage GND of the scan electrode Y. Even in this case, it is possible to stabilize the horizontal address discharge.

Meanwhile, as in the case of FIG. 26, the scan sustain period SSP may be omitted between the vertical scan subfield VSSF and the horizontal scan subfield HSSF.

This may be the case where a sufficient amount of wall charge is formed in the discharge cell in the vertical scan subfield VSSF to generate a sufficiently stable horizontal address discharge in the subsequent horizontal scan subfield HSSF.

For example, as in the case of FIG. 16, the magnitude of the voltage of the touch scan signal TSP is greater than that of the scan signal SP, and as in the case of FIG. 17, the scan is performed in the vertical scan address period VSAP. When the touch scan signal TSP is supplied to the electrode Y, the voltage Vx1 of the address electrode X is supplied to the address electrode X in the address period AP of the general subfield. The scan sustain period SSP may be omitted between the vertical scan subfield VSSF and the horizontal scan subfield HSSF when the voltage Vd is higher than.

In this case, in order to stabilize the horizontal address discharge in the horizontal scan address period HSAP, the maximum voltage Vx2 of the touch data signal TDP is higher than the maximum voltage Vd of the data signal DP as in the case of FIG. 20. As shown in FIG. 21, the horizontal scan subfield HSSF of one of the electrodes to which the last touch sustain signal TSUS _Last of the scan electrode Y or the sustain electrode Z is supplied in the scan sustain period SSP. It may be desirable for the voltage at to be lower than the voltage at the horizontal scan subfield (HSSF) of the other electrode.

Meanwhile, as in the case of FIG. 27A, the data signal DP supplied to the address electrode in the address period AP of the general subfield maintains the first rising period rp1 and the maximum voltage at which the voltage rises. The first sustain period mp1 and the first falling period fp1 at which the voltage falls may be included.

In addition, as in the case of FIG. 27B, the touch data signal TDP supplied to the address electrode X in the horizontal scan address period HSAP has a second rising period rp2 and a maximum voltage at which the voltage increases. It may include a second sustain period (mp2) for maintaining a and a second falling period (fp2) that the voltage falls.

Here, the length of the second rising period rp2 of the touch data signal TDP may be shorter than the length of the first rising period rp1 of the data signal DP, and the second falling period of the touch data signal TDP. The length of fp2 may be shorter than the length of the first falling period fp1 of the data signal DP.

To this end, the present invention may include a driving circuit having the configuration as shown in FIG. The driving circuit of FIG. 28 may be a driving circuit for supplying the touch data signal TDP or the data signal DP to the address electrode X. 28 to 30, it is assumed that the maximum voltage of the touch data signal TDP and the maximum voltage of the data signal DP are the same.

The data drive integrated circuit unit 800 is preferably formed as a module independent of the data voltage supply controller 810 and the energy recovery circuit unit 820. For example, it is preferable to be formed in the form of one chip on a tape carrier package (TCP).

In addition, the data drive integrated circuit unit 800 may include a top switch unit Qt and a bottom switch unit Qb.

Here, one end of the top switch unit Qt may be commonly connected to the data voltage supply controller 810 and the energy recovery circuit unit 820, and the other end thereof may be connected to one end of the bottom switch unit Qb.

In addition, the other end of the bottom switch unit Qb is grounded GND, and between the other end of the top switch unit Qt and one end of the bottom switch unit Qb (the second node, n2) is connected to the address electrode X. Can be connected.

The energy recovery circuit unit 820 may include an energy storage unit 821, an energy supply control unit 822, an energy recovery control unit 823, and an inductor unit 824.

The energy storage unit 821 includes an energy storage capacitor unit C, and stores the energy to be supplied to the address electrode X of the plasma display panel by using the energy storage capacitor unit C, and also displays the plasma display. The reactive energy recovered from the panel can be stored.

The energy supply control unit 822 includes an energy supply control switch unit Q2, and from the energy storage capacitor unit C to the address electrode X of the plasma display panel using the energy supply control switch unit Q2. It is possible to form a supply path of the supplied energy.

The energy supply controller 822 may be connected to one end of the capacitor C for energy storage.

The energy supply control unit 822 may further include a reverse current prevention diode unit D1 for preventing a reverse current from flowing through the energy supply control switch unit Q2 to the energy storage unit 821. have.

The energy recovery control unit 823 includes an energy recovery control switch unit Q3, and uses the energy recovery control switch unit Q3 from the address electrode X of the plasma display panel to the energy storage capacitor unit C. A recovery path of the recovered energy can be formed.

One end of the energy recovery control unit 823 may be commonly connected to the above-described energy storage capacitor unit C and the energy supply control unit 822.

The energy recovery control unit 823 may further include a reverse current prevention diode unit D2 for preventing a reverse current from flowing from the energy storage unit 821 to the energy recovery control switch unit Q3.

The inductor unit 824 includes a resonant inductor L, and the energy stored in the above-described energy storage unit 821 using the resonant inductor L is the address electrode X of the plasma display panel through LC resonance. ) And the reactive energy of the plasma display panel may be recovered to the energy storage unit 821 through LC resonance.

Here, FIG. 28 illustrates only an example of the data driver of the plasma display device of the present invention, and the present invention may not be limited to FIG. 28.

The operation of the driving unit of FIG. 28 will be described with reference to FIGS. 29 to 30 as follows.

29 to 30 are views for explaining the operation of the driving circuit according to the present invention of FIG.

First, referring to FIG. 29, an operation timing of a driving circuit for supplying the touch data signal TDP as shown in FIG. 27B to the address electrode X is shown.

For example, in the second rising period rp2, the data voltage supply control switch Q1 of the data voltage supply controller 810 and the top switch Qt of the data drive integrated circuit 800 may be turned on. Turn-On).

In this case, the data voltage Vd supplied by the data voltage source may be supplied to the address electrode X through the B1 path Path B1 via the top switch unit Qt. Accordingly, the length of the second rising period rp2 of the touch data signal DP may be shortened relatively.

Thereafter, when the data voltage Vd is continuously supplied to the address electrode X through the top switch unit Qt in the second sustain period mp2, the voltage of the touch data signal TDP is the maximum voltage, that is, the data voltage ( Vd) can be maintained.

Thereafter, in the second falling period fp2, the data voltage supply control switch Q1 of the data voltage supply controller 810 and the top switch Qt of the data drive integrated circuit 800 are turned off. Off). In addition, the bottom switch unit Qb of the data drive integrated circuit unit 800 may be turned on.

In this case, since the address electrode X is grounded, the voltage of the ground level GND is supplied to the address electrode X through the B2 path Path B2, so that the voltage of the address electrode X may drop.

Accordingly, the length of the second falling period fp2 of the touch data signal TDP may be relatively short.

Next, referring to FIG. 30, an operation timing of a driving circuit for supplying the data signal DP as shown in FIG. 27A to the address electrode X is illustrated.

For example, in the first rising period rp1, the data voltage supply control switch Q1 of the data voltage supply controller 810 and the bottom switch Qb of the data drive integrated circuit 800 may be turned off. The top switch unit Qt of the data drive integrated circuit unit 800 and the energy supply control switch unit Q2 of the energy supply control unit 822 of the energy recovery circuit unit 820 may be turned on.

Then, the energy stored in the energy storage capacitor unit C of the energy storage unit 821 passes through the energy supply control unit 822, the inductor unit 824, and the top switch unit Qt of the data drive integrated circuit unit 800. The A1 path is supplied to the address electrode X of the plasma display panel through the path A1.

At this time, the voltage of the energy supplied to the address electrode X of the plasma display panel rises gently as in the period d1 due to the occurrence of LC resonance in the inductor unit 824. That is, a voltage gradually rising to the address electrode X is supplied.

Accordingly, the length of the first rising period rp1 of the data signal DP may be longer than the length of the second rising period rp2 of the touch data signal TDP.

Subsequently, in the first sustain period mp1, the data voltage supply control switch Q1 of the data voltage supply controller 810 may be turned on.

Then, when the data voltage Vd is continuously supplied to the address electrode X through the top switch unit Qt, the voltage of the data signal DP may maintain the maximum voltage, that is, the data voltage Vd.

Thereafter, in the first falling period fp1, the energy recovery control switch Q3 of the energy recovery control unit 823 of the energy recovery circuit unit 820 is turned on, and the top switch unit Qt of the data drive integrated circuit unit 800 is turned on. ) Is on.

In addition, the energy supply control switch unit Q2 of the energy recovery circuit unit 820, the data voltage supply control switch unit Q1 of the data voltage supply control unit 810, and the bottom switch unit Qb of the data drive integrated circuit unit 800. Are off respectively.

Then, the reactive energy of the address electrode X is determined by the top switch unit Qt, the inductor unit 824, and the energy recovery control unit 823 of the data drive integrated circuit unit 800. It may be recovered in the unit (C).

In this case, the voltage of the address electrode X may gradually decrease due to the occurrence of LC resonance in the inductor unit 824. That is, a voltage that gradually falls to the address electrode X is supplied.

Accordingly, the length of the first falling period fp1 of the data signal DP may be longer than the length of the second falling period fp2 of the touch data signal TDP.

As such, the length of the second rising period rp2 of the touch data signal TDP is shorter than the length of the first rising period rp1 of the data signal DP, and the second falling period of the touch data signal TDP ( When the length of fp2 is shorter than the length of the first falling period fp1 of the data signal DP, it is possible to increase the intensity of the vertical address discharge and the horizontal address discharge to improve the detection efficiency and precision of the touch position. .

Meanwhile, another example of the structure of the general subfield disposed after the vertical scan subfield VSSF and the horizontal scan subfield HSSF will be described with reference to FIG. 31. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 31, the first general subfield subsequent to the horizontal scan subfield HSSF, that is, the first subfield SF1 has a pre-reset period PRP, a reset period RP, an address period AP, and a sustain. It may include a period SP.

In the reset period RP, the first reset signal RS1 and the second reset signal RS2 may be supplied to the scan electrode Y.

Here, the first reset signal RS1 may include a rising ramp signal including a first rising ramp signal RU1 and a second rising ramp signal Second Ramp-Up RU2 in which the voltage gradually increases. RU) and a falling ramp signal RD including a first falling ramp signal RD1 and a second falling ramp signal RD2 in which the voltage gradually decreases. .

The second reset signal RS2 may include a third ramp signal RU3 in which the voltage gradually rises, and a third ramp lamp RD3 in which the voltage gradually falls. Can be.

For example, the first rising ramp signal RU1 may be supplied to the scan electrode and the second rising ramp signal RU2 may be supplied to the scan electrode in the first setup period SU1 of the reset period RP. . In the first set-down period SD1 after the first setup period SU1, the first falling ramp signal RD1 and the second falling ramp signal RD2 may be sequentially supplied to the scan electrode.

Here, the slope of the first rising ramp signal RU1, that is, the rate of change in voltage per hour may be greater than the rate of change in voltage per hour of the second rising ramp signal RU2. In addition, an hourly voltage change rate of the first falling ramp signal RD1 may be greater than an hourly voltage change rate of the second falling ramp signal RD2.

When the first and second rising ramp signals are supplied to the scan electrodes, a weak dark discharge, that is, a setup discharge occurs in the discharge cells 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 first and second falling ramp signals are supplied to the scan electrodes, 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 first set-down period SD1 of the reset period RP, the tenth sustain reference voltage Vz10 may be supplied to the sustain electrode. In this case, the setdown discharge can be stabilized.

In the second set-up period SU2 of the reset period RP, the third rising ramp signal RU3 is supplied to the scan electrode, and in the second set-down period SD2, the third falling ramp signal RD3 is supplied to the scan electrode. Can be supplied.

As such, when the third rising ramp signal RU3 and the third falling ramp signal RD3 are supplied to the scan electrode, the wall charges in the discharge cell may be more uniformly distributed.

Here, the first reset signal RS1 may be substantially the same as the first scan reset signal SRS1 of FIG. 12. For example, the maximum and minimum voltages of the first reset signal RS1 may be substantially the same as the maximum and minimum voltages of the first scan reset signal SRS1 of FIG. 12.

In addition, the second reset signal RS2 may be substantially the same as the second scan reset signal SRS2 of FIG. 12.

In the address period after the reset period RP, the scan signal SP may be sequentially supplied to the scan electrode Y. In addition, when the scan signal SP is supplied to the scan electrode Y, the data signal DP may be supplied to the address electrode X. FIG. Accordingly, address discharge may occur in the discharge cell.

In the sustain period SP after the address period AP, the sustain signal SUS may be supplied to at least one of the scan electrode Y and the sustain electrode Z. FIG.

Subsequently, in the second subfield SF2 successive to the first subfield SF1, the fourth ramp lamp RD4 in which the ramp ramp is gradually supplied without supplying the ramp lamp signal to the scan electrode Y in the reset period. Can be supplied. In this case, since the reset discharge can be sufficiently generated in the reset period of the second subfield SF2 by using the wall charges formed in the sustain period SP of the first subfield SF1, the second subfield SF2. It is considered that the rising ramp signal is omitted in the reset period.

On the other hand, in the vertical scan address period VSAP of the vertical scan subfield VSFF, it is possible to generate a vertical address discharge between the scan electrode Y and the sustain electrode Z. Hereinafter, the description of the parts described in detail above will be omitted.

That is, as described with reference to FIG. 5, the remote control apparatus 200Q of the broadcast signal receiver according to the present invention includes the scan electrode Y and the sustain electrode Z in the vertical scan address period VSAP of the vertical scan subfield VSSF. Is sensed by the discharge generated between the < RTI ID = 0.0 >), < / RTI > ) And light by the discharge generated between the address electrode (X) can be detected.

In other words, in the broadcast signal receiver according to the present invention, the vertical coordinate of the touch position is a discharge generated between the scan electrode Y and the sustain electrode Z in the vertical scan address period VSAP of the vertical scan subfield VSSF. In the horizontal scan address period (HSAP) of the horizontal scan subfield (HSSF), a discharge generated between the scan electrode (Y) and the address electrode (X) or between the sustain electrode (Z) and the address electrode (X) is obtained. It is possible to acquire the horizontal coordinate of the touch position by the discharge which arises.

For this purpose, as in the case of FIG. 32, the voltage of the sustain electrode Z is greater than the voltage of the address electrode X while the touch scan signal TSP is supplied to the scan electrode Y in the vertical scan address period VSAP. Can be higher. For example, the second scan sustain reference signal having the second sustain reference voltage Vz2 is supplied to the sustain electrode Z while the touch scan signal TSP is supplied to the scan electrode Y in the vertical scan address period VSAP. (Szb2) can be supplied. In addition, the voltage of the ground level GND may be supplied to the address electrode X.

In this case, as shown in FIG. 33, when the touch scan signal TSP is supplied to the scan electrode Y in the vertical scan address period VSAP, a vertical address discharge is generated between the scan electrode Y and the sustain electrode Z. FIG. May occur.

In addition, in the horizontal scan address period HSAP of the horizontal scan subfield HSSF after the vertical scan subfield VSSF, the scan electrode Y and the address electrode X or the sustain electrode Z and the address electrode X are It is possible to generate a horizontal address discharge in between.

As such, vertical address discharge is generated between the scan electrode Y and the sustain electrode Z in the vertical scan address period VSAP, and the scan electrode Y and the address electrode X or in the horizontal scan address period HSAP. When the horizontal address discharge is generated between the sustain electrode Z and the address electrode X, the horizontal address discharge can be further stabilized.

In other words, when the vertical address discharge is generated between the scan electrode Y and the sustain electrode Z in the vertical scan address period VSAP, the wall formed on the address electrode X during the vertical scan address period VSAP. The charge can be maintained without being consumed. Accordingly, since the amount of wall charges to be used in the horizontal address discharge occurring in the horizontal scan address period HSAP can be secured sufficiently, the intensity of the horizontal address discharge can be sufficiently strong.

In this case, it is possible to make the voltage of the sustain electrode Z higher than the voltage of the sustain electrode Z in the address period AP of the general subfield in the horizontal scan address period HSAP to further stabilize the horizontal address discharge. Do.

For example, as in the case of FIG. 34, the voltage of the sustain electrode Z is applied to the second sustain reference voltage Vz2 while the touch scan signal TSP is supplied to the scan electrode Y in the vertical scan address period VSAP. ) May be higher than the voltage Vzb of the sustain electrode Z in the address period AP of the general subfield.

Here, the second sustain reference voltage Vz2 is a voltage of the sustain signal SUS supplied to at least one of the scan electrode Y and the sustain electrode Z in the sustain period SP of the general subfield, that is, the sustain voltage Vs. Approximately the same as

Meanwhile, the touch scan signals TSP supplied to at least two scan electrodes Y in the vertical scan address period VSAP of the vertical scan subfield VSSF may overlap. Hereinafter, the description of the parts described in detail above will be omitted.

For example, as in the case of FIG. 35, the touch scan signals TSP supplied to at least two scan electrodes Y disposed adjacent to each other may overlap each other. In FIG. 35, two adjacent scan electrodes Y, for example, the touch scan signal TSP supplied to the first scan electrode Y1 and the touch scan signal TSP supplied to the second scan electrode Y2 are Although only the case of overlapping with each other is described, it may be possible that the touch scan signals TSP supplied to the adjacent three and four scan electrodes Y overlap each other. Hereinafter, for convenience of description, the case where the touch scan signals TSP supplied to two adjacent scan electrodes Y overlap each other will be described as an example.

Preferably, the touch scan signal TSP may be supplied to the first scan electrode Y1 and the second scan electrode Y2 at the same time. In other words, the touch scan signal TSP supplied to the first scan electrode Y1 and the touch scan signal TSP supplied to the second scan electrode Y2 may be synchronized.

As such, when the touch scan signals TSP supplied to the at least two scan electrodes Y overlap, the length of the vertical scan address period VSAP may be reduced. Accordingly, the length of the general subfield SF may be increased, so that an image may be advantageous in implementing grayscale.

Referring to FIG. 36, when the first, second, third, and fourth scan electrodes Y1 to Y4 of the plurality of scan electrodes Y are assumed, the first touch scan signal TSP1 supplied to the first scan electrode Y1 is illustrated. ) May overlap the second touch scan signal TSP2 supplied to the second scan electrode Y2.

On the other hand, the second touch scan signal TSP2 supplied to the second scan electrode Y2 and the third touch scan signal TSP3 supplied to the third scan electrode Y3 may be spaced apart from each other by Δt. have.

Alternatively, as in the case of FIG. 37, the first touch scan signal TSP1 supplied to the first scan electrode Y1 partially overlaps the second touch scan signal TSP2 supplied to the second scan electrode Y2. May be partially overlapped.

The second touch scan signal TSP2 supplied to the second scan electrode Y2 and the third touch scan signal TSP3 supplied to the third scan electrode Y3 may be spaced apart from each other by Δt2 in time. . Δt1 may be greater than Δt2.

The TSP may partially overlap the touch scan signal TSP supplied to the fourth scan electrode Y4.

Alternatively, the overlapping degree of two touch scan signals TSP may be different from the overlapping degree of two other touch scan signals TSP.

For example, as in the case of FIG. 40, the first touch scan signal TSP1 supplied to the first scan electrode Y1 is entirely up to the second touch scan signal TSP2 supplied to the second scan electrode Y2. The second touch scan signal TSP2 supplied to the second scan electrode Y2 and the third touch scan signal TSP3 supplied to the third scan electrode Y3 may partially overlap each other.

The second touch scan signal TSP2 supplied to the second scan electrode Y2 and the third touch scan signal TSP3 supplied to the third scan electrode Y3 may overlap each other by Δt5. Here,? T4 can be larger than? T5.

Meanwhile, the touch data signal TDP supplied to at least two address electrodes X may be overlapped in the horizontal scan address period HSAP of the horizontal scan subfield HSSF. Hereinafter, the description of the parts described in detail above will be omitted.

For example, as in the case of FIG. 41, the touch data signals TDP supplied to at least two address electrodes X disposed adjacent to each other may overlap each other. In FIG. 41, the touch data signal TDP supplied to two adjacent address electrodes X, for example, the first address electrode X1 and the touch data signal TDP supplied to the second address electrode X2 are Although only the case of overlapping with each other is described, it may be possible that the touch data signals TDP supplied to the adjacent three and four address electrodes X overlap each other. For convenience of explanation, a case where the touch data signals TDP supplied to two adjacent address electrodes X overlap each other will be described as an example.

Preferably, the touch data signal TDP may be supplied to the first address electrode X1 and the second address electrode X2 at the same time. In other words, the first touch data signal TDP1 supplied to the first address electrode X1 and the second touch data signal TDP2 supplied to the second address electrode X2 may be synchronized.

As such, when the touch data signals TDP supplied to the at least two address electrodes X overlap, the length of the horizontal scan address period HSAP can be reduced. Accordingly, the length of the general subfield SF may be increased, so that an image may be advantageous in implementing grayscale.

Referring to FIG. 42, assuming the first, second, third, and fourth address electrodes X1 to X4 among the plurality of address electrodes X, the first touch data signal TDP1 supplied to the first address electrode X1. ) May overlap the second touch data signal TDP2 supplied to the second address electrode X2. For example, the first touch data signal TDP1 supplied to the first address electrode X1 may be fully overlapped with the second touch data signal TDP2 supplied to the second address electrode X2. have.

The second touch data signal TDP2 supplied to the second address electrode X2 and the third touch data signal TDP3 supplied to the third address electrode X3 may be spaced apart from each other by Δt10 in time. . Δt11 may be greater than Δt10.

Alternatively, as in the case of FIG. 44, the touch data signals TDP supplied to the first, second and third address electrodes X1 to X3 may overlap each other.

Alternatively, the touch data signals TDP supplied to the adjacent address electrodes X may be partially overlapped sequentially.

The touch data signal TDP supplied to the second address electrode X2 partially overlaps the touch data signal TDP supplied to the third data electrode X3, and the touch data signal supplied to the third address electrode X3. The TDP may partially overlap the touch data signal TDP supplied to the fourth address electrode X4.

Alternatively, the overlapping degree of two touch data signals TDP may be different from the overlapping degree of two other touch data signals TDP.

For example, as in the case of FIG. 46, the first touch data signal TDP1 supplied to the first address electrode X1 and the second touch data signal TDP2 supplied to the second address electrode X2 are entirely. The second touch data signal TDP2 supplied to the second address electrode X2 and the third touch data signal TDP3 supplied to the third address electrode X3 may partially overlap each other.

In other words, the first touch data signal TDP1 supplied to the first address electrode X1 may overlap the second touch data signal TDP2 supplied to the second address electrode X2 in time by Δt14. The second touch data signal TDP2 supplied to the second address electrode X2 and the third touch data signal TDP3 supplied to the third address electrode X3 may overlap in time by Δt15. (DELTA) t14 can be larger than (DELTA) t15 here.

On the other hand, as shown in Figure 47, in the plasma display panel according to the present invention the number of address electrodes (X1 ~ Xm) arranged side by side in the horizontal direction of the panel is the scan electrodes (Y1 ~ ~) arranged in parallel in the longitudinal direction of the panel May be more than the number of Yn). Accordingly, the length of the horizontal scan address period HSAP may be longer than the length of the vertical scan address period VSAP.

In consideration of this, overlapping at least two touch data signals TDP with each other in the horizontal scan address period HSAP is compared to overlapping at least two touch scan signals TSP with each other in the vertical scan address period VSAP. It may be effective to reduce the length of the subfield.

Accordingly, as shown in FIG. 47B, the touch data signals TDP supplied to two adjacent address electrodes X overlap each other, and as shown in FIG. 47A, two adjacent scans It is possible to prevent the touch scan signal TSP supplied to the electrode Y from overlapping.

Alternatively, the number of overlapping touch data signals TDP may be larger than the number of overlapping touch scan signals TSP. For example, as in the case of FIG. 47B, the touch data signals TDP supplied to the first, second, and third address electrodes X1, X2, and X3 overlap each other, and as shown in FIG. 48A. As in the case, the touch scan signals TSP supplied to the first and second scan electrodes Y1 and Y2 may overlap each other.

Alternatively, the touch scan signals TSP supplied to at least two scan electrodes Y that are not adjacent to each other may overlap each other.

For example, as in the case of FIG. 49, the Yb scan electrode of the plurality of scan electrodes Y may be disposed between the Ya scan electrode and the Yc scan electrode. In this case, the touch scan signal TSP supplied to the Ya scan electrode and the touch scan signal TSP supplied to the Yc scan electrode may overlap each other. In addition, the touch scan signal TSP supplied to the Ya scan electrode and the touch scan signal TSP supplied to the Yc scan electrode may not overlap the touch scan signal supplied to the Yb scan electrode.

The above case may be applied when the touch scan signal TSP is sequentially supplied from each of the divided regions when the panel is divided into a plurality of regions.

For example, as in the case of FIG. 50A, among the plurality of scan electrodes Y, Y1 to Y (n / 2) scan electrodes are defined as the first scan electrode group G1 and Y ((n / 2). +1) to Y (n) scan electrodes may be divided into a second scan electrode group G2.

In this case, the touch scan signal TSP is sequentially supplied from the Y1 scan electrode to the Y (n / 2) scan electrode among the scan electrodes Y1 to Y (n / 2) of the first scan electrode group G1, From the scan electrodes Y ((n / 2) +1) to Y (n) of the second scan electrode group G2 to the scan electrodes Y ((n / 2) +1) to Y (n) It is possible to supply the touch scan signal TSP.

In this case, the touch scan signal TSP supplied to the Y1 scan electrode may overlap the touch scan signal TSP supplied to the Y ((n / 2) +1) scan electrode.

As described above, when the panel is divided into a plurality of regions and the touch scan signal TSP is sequentially supplied to the plurality of scan electrodes Y in each region, the length of the vertical scan address period VSAP can be reduced.

51, the touch scan signal TSP1 supplied to the Y1 scan electrode is the touch scan signal TSP ((n / 2) +1 supplied to the Y ((n / 2) +1) scan electrode. It is possible that the touch scan signal TSP1 supplied to the Y1 scan electrode does not overlap the touch scan signal TSP2 supplied to the Y2 scan electrode while overlapping with)).

Alternatively, as in the case of FIG. 52, the touch scan signal TSP1 supplied to the Y1 scan electrode is the touch scan signal TSP ((n / 2) +1 supplied to the Y ((n / 2) +1) scan electrode. )), While the touch scan signal TSP ((n / 2) +1) supplied to the Y ((n / 2) +1) scan electrode is overlapped by Δt22, the touch scan signal ( TSP2) may be spaced apart in time by Δt23. Δt22 may be larger than Δt23.

Alternatively, the direction in which the touch scan signal TSP is supplied from each scan electrode group may be changed.

For example, as in the case of FIG. 53, touch scan is sequentially performed from the Y1 scan electrode to the Y (n / 2) scan electrode among the scan electrodes Y1 to Y (n / 2) of the first scan electrode group G1. The signal TSP is supplied and Y ((n / 2) from the Y (n) scan electrode of the scan electrodes Y ((n / 2) +1) to Y (n) of the second scan electrode group G2 It is possible to sequentially supply the touch scan signal TSP to the scan electrode.

Alternatively, as in the case of FIG. 54, the touch scan signal (sequentially from the Y (n / 2) scan electrode to the Y1 scan electrode among the scan electrodes Y1 to Y (n / 2) of the first scan electrode group G1) may be sequentially applied. TSP is supplied and Y ((n / 2) +1) from the scan electrodes Y ((n / 2) +1) to Y (n) of the second scan electrode group G2 to Y ( n) It is possible to sequentially supply the touch scan signal TSP to the scan electrode.

In the above, the case in which the plurality of scan electrodes Y is divided into two scan electrode groups G1 and G2 has been described. However, the number of scan electrode groups may be variously changed.

For example, as in the case of FIG. 55A, among the plurality of scan electrodes Y, Y1 to Y (n / 3) scan electrodes are defined as the first scan electrode group G1 and Y ((n / 3). Dividing the +1) to Y (2n / 3) scan electrodes into the second scan electrode group G2 and the Y ((2n / 3) +1) to Y (n) scan electrodes into the third scan electrode group G3 can do. In the panel, an area corresponding to the first scan electrode group G1 is referred to as a first area, an area corresponding to the second scan electrode group G2 is referred to as a second area, and corresponds to a third scan electrode group G3. The region to be referred to as a third region.

Here, as in the case of FIG. 55B, sequentially from the Y1 scan electrode to the Y (n / 3) scan electrode among the scan electrodes Y1 to Y (n / 3) of the first scan electrode group G1. The touch scan signal TSP is supplied and Y ((n / 3) +1 of the scan electrodes Y ((n / 3) +1) to Y (2n / 3)) of the second scan electrode group G2. ) The touch scan signal TSP is sequentially supplied from the scan electrode to the Y (2n / 3) scan electrode, and the scan electrodes Y ((2n / 3) +1) to Y (of the third scan electrode group G3 are sequentially supplied. It is possible to sequentially supply the touch scan signal TSP from the Y ((2n / 3) +1) scan electrode to the Y (n) scan electrode.

In this case, the touch scan signal TSP supplied to the Y1 scan electrode, the Y ((n / 3) +1) scan electrode, and the Y ((2n / 3) +1) may overlap each other.

Alternatively, as in the case of FIG. 56, the touch scan signal TSP1 supplied to the Y1 scan electrode is the touch scan signal TSP ((n / 2) +1 supplied to the Y ((n / 2) +1) scan electrode. )) And touch scan signal TSP2 supplied to the Y2 scan electrode and touch scan signal TSP ((n / 2) +1) supplied to the Y ((n / 2) +1) scan electrode. ) Can overlap by? T31. Here,? T30 can be larger than? T31.

In addition, the touch scan signal TSP1 supplied to the Y1 scan electrode may not overlap the touch scan signal TSP2 supplied to the Y2 scan electrode.

In this case, the start point of discharge generated by the touch scan signal TSP1 supplied to the Y1 scan electrode and the touch scan signal TSP ((n / 2) supplied to the Y ((n / 2) +1) scan electrode The starting point of the discharge generated by +1)) may be different. Accordingly, in the broadcast signal receiver according to the present invention, the discharge generated by the touch scan signal TSP1 supplied to the Y1 scan electrode and the touch scan signal TSP (supplied to the Y ((n / 2) +1) scan electrode are provided. Since the discharge generated by (n / 2) +1)) can be distinguished and confirmed, it is possible to easily check whether the touch position is located in the first region or the second region on the panel.

Alternatively, the touch data signals TDP supplied to at least two address electrodes X which are not adjacent to each other may overlap each other.

For example, as in the case of FIG. 57, an Xb address electrode among the plurality of address electrodes X may be disposed between the Xa address electrode and the Xc address electrode. In this case, the touch data signal TDP supplied to the Xa address electrode and the touch data signal TDP supplied to the Xc address electrode may overlap each other. In addition, the touch data signal TDP supplied to the Xa address electrode and the touch data signal TDP supplied to the Xc address electrode may not overlap with the touch data signal TDP supplied to the Xb address electrode.

The above case may be applied to a case in which the touch data signal TDP is sequentially supplied from each of the divided regions when the panel is divided into a plurality of regions.

For example, as in the case of FIG. 58A, X1 to X (m / 2) address electrodes among the plurality of address electrodes X are selected from the first address electrode group G10 and X ((m / 2). The +1) to X (m) address electrodes can be divided into the second address electrode group G11. In the panel, a region corresponding to the first address electrode group G10 may be referred to as a first region, and a region corresponding to the second address electrode group G11 may be referred to as a second region.

In this case, the touch data signal TDP is sequentially supplied from the X1 address electrode to the X (m / 2) address electrode among the address electrodes X1 to X (m / 2) of the first address electrode group G10, From the address electrodes X ((m / 2) +1) to X (m) of the second address electrode group G11, sequentially from the X ((m / 2) +1) address electrodes to the X (m) address electrodes It is possible to supply the touch data signal TDP.

In this case, the touch data signal TDP supplied to the X1 address electrode can overlap the touch data signal TDP supplied to the X ((m / 2) +1) address electrode.

As described above, when the panel is divided into a plurality of regions and the touch data signals TDP are sequentially supplied to the plurality of address electrodes X in each region, the length of the horizontal scan address period HSAP can be reduced.

Meanwhile, as in the case of FIG. 59, the touch data signal TDP1 supplied to the X1 address electrode is the touch data signal TDP ((m / 2) +1 supplied to the X ((m / 2) +1) address electrode. It is possible that the touch data signal TDP1 supplied to the X1 address electrode does not overlap the touch data signal TDP2 supplied to the X2 address electrode while fully overlapping with)).

Alternatively, as in the case of FIG. 60, the touch data signal TDP1 supplied to the X1 address electrode is the touch data signal TDP ((m / 2) +1 supplied to the X ((m / 2) +1) address electrode. )), While the touch data signal TDP ((m / 2) +1) supplied to the X ((m / 2) +1) address electrode is overlapped by Δt33, the touch data signal ( TDP2) may be spaced apart in time by Δt34. DELTA t33 can be larger than DELTA t34.

Alternatively, the direction in which the touch data signal TDP is supplied from each address electrode group may be changed.

For example, as in the case of FIG. 61, touch data sequentially from the X1 address electrode to the X (m / 2) address electrode among the address electrodes X1 to X (m / 2) of the first address electrode group G10. The signal TDP is supplied, and from the address electrodes X ((m / 2) +1) to X (m) of the second address electrode group G11 to the X ((m / 2) It is possible to sequentially supply the touch data signal TDP to the address electrode.

Alternatively, as in the case of FIG. 62, the touch data signal (sequentially from the X (m / 2) address electrode to the X1 address electrode among the address electrodes X1 to X (m / 2) of the first address electrode group G10) may be sequentially obtained. TDP) and X ((m / 2) +1) from the address electrodes X ((m / 2) +1) to X (m) of the second address electrode group G11 to X ( m) It is possible to sequentially supply the touch data signal TDP to the address electrode.

In the above, the case where the plurality of address electrodes X is divided into two address electrode groups G10 and G11 has been described. However, the number of address electrode groups may be variously changed.

For example, as in the case of FIG. 63A, X1 to X (m / 3) address electrodes among the plurality of address electrodes X are selected from the first address electrode group G10 and X ((m / 3). The +1) to X (2m / 3) address electrodes are divided into the second address electrode group G11, and the X ((2m / 3) +1) to X (m) address electrodes are divided into the third address electrode group G12. can do. In the panel, an area corresponding to the first address electrode group G10 is called a first area, and an area corresponding to the second address electrode group G11 is called a second area, and corresponds to the third address electrode group G12. The region to be referred to as a third region.

Here, as in the case of FIG. 63B, sequentially from the X1 address electrode to the X (m / 3) address electrode among the address electrodes X1 to X (m / 3) of the first address electrode group G10. The touch data signal TDP is supplied and X ((m / 3) +1 of the address electrodes X ((m / 3) +1) to X (2m / 3)) of the second address electrode group G11. The touch data signal TDP is sequentially supplied from the address electrode to the X (2m / 3) address electrode, and the address electrodes X ((2m / 3) +1) to X (of the third address electrode group G12 are sequentially supplied. m)), it is possible to sequentially supply the touch data signal TDP from the X ((2m / 3) +1) address electrode to the X (m) address electrode.

In this case, the touch data signal TDP supplied to the X1 address electrode, the X ((m / 3) +1) address electrode, and the X ((2m / 3) +1) may overlap each other.

Alternatively, as in the case of FIG. 64, the touch data signal TDP1 supplied to the X1 address electrode is the touch data signal TDP ((m / 2) +1 supplied to the X ((m / 2) +1) address electrode. )) And touch data signal TDP2 supplied to the X2 address electrode and touch data signal TDP ((m / 2) +1) supplied to the X ((m / 2) +1) address electrode. ) Can overlap by? T41. Here,? T40 can be larger than? T41.

In addition, the touch data signal TDP1 supplied to the X1 address electrode may not overlap with the touch data signal TDP2 supplied to the X2 address electrode.

In this case, the start point of the discharge generated by the touch data signal TDP1 supplied to the X1 address electrode and the touch data signal TDP ((m / 2) supplied to the X ((m / 2) +1) address electrode. The starting point of the discharge generated by +1)) may be different. Accordingly, in the broadcast signal receiver according to the present invention, the discharge generated by the touch data signal TDP1 supplied to the X1 address electrode and the touch data signal TDP (supplied to the X ((m / 2) +1) address electrode are provided. Since the discharge generated by (m / 2) +1)) can be distinguished and confirmed, it is possible to easily check whether the touch position is located in the first region or the second region on the panel.

On the other hand, as described with reference to FIG. 47, in the plasma display panel according to the present invention, the number of address electrodes X1 to Xm arranged side by side in the horizontal direction of the panel is equal to the number of scan electrodes Y1-side arranged in the vertical direction of the panel. It may be larger than the number of Yn), and thus the length of the horizontal scan address period HSAP may be longer than the length of the vertical scan address period VSAP.

Considering this, as in the case of FIG. 65, in the horizontal scan address period HSAP, the touch data signal TDP is sequentially supplied to the plurality of address electrodes of the first address electrode group G10 and the second address electrode group is provided. It is possible to sequentially supply the touch data signal TDP to the plurality of address electrodes of G11, and in the vertical scan address period VSSF, the touch scan signal TSP is sequentially applied to the plurality of scan electrodes Y1 to Yn. May be possible.

Meanwhile, the supply direction / supply order of the touch scan signal TSP may be different in the vertical scan address period VSAP in different frames. In addition, the supply direction / supply order of the touch data signal TDP in the horizontal scan address period HSAP may be different in different frames.

For example, as in the case of FIG. 66A, the first subfield SF1 and the second subfield SF2 among the plurality of subfields are scanned in the first frame Frame1 among the plurality of frames. Can be set to In detail, in the first frame Frame1, the first subfield SF1 of the plurality of subfields is set as the vertical scan subfield VSSF, and the second subfield SF2 is set as the horizontal scan subfield HSSF. Can be set.

In addition, as illustrated in FIG. 66B, in the second frame Frame2, the first subfield SF1 of the plurality of subfields is set as the vertical scan subfield VSSF, and the second subfield SF2 is set. Can be set to the horizontal scan subfield (HSSF).

Here, the supply order of the touch scan signals TSP supplied to the plurality of scan electrodes Y in the vertical scan address period VSAP of the vertical scan subfield VSSF of the first frame F1 is the second frame F2. In the vertical scan address period VSAP of the vertical scan subfield VSSF of FIG. 3, the touch scan signal TSP may be different from the supply order of the touch scan signals TSP.

For example, as illustrated in FIG. 66C, the touch scan signal TSP is applied from the Y1 scan electrode to the Yn scan electrode in the vertical scan address period VSAP of the vertical scan subfield VSSF of the first frame F1. It is possible to supply sequentially, and in the vertical scan address period VSAP of the vertical scan subfield VSSF of the second frame F2 as shown in FIG. 66D, the Yn scan electrode is different from that of the first frame F1. To the Y1 scan electrode, the touch scan signal TSP may be sequentially supplied.

In other words, in the first frame F1, the supply point of the touch scan signal TSP supplied to the Y1 scan electrode among the plurality of scan electrodes Y is the supply point of the touch scan signal TSP supplied to the Yn scan electrode. On the contrary, in the second frame F2, the supply point of the touch scan signal TSP supplied to the Yn scan electrode among the plurality of scan electrodes Y is the supply point of the touch scan signal TSP supplied to the Y1 scan electrode.

Each of the touches may be detected at 100 to 130.

In order to prevent the malfunction of the acquisition of the touch position, it is possible to include identification information for identifying each plasma display panel included in the multi-plasma display device in the scan subfield.

Preferably, the number or arrangement pattern of the touch sustain signals TSUS corresponding to each plasma display panel included in the multi-plasma display device may be different from each other.

For example, as in the case of FIG. 78A, the vertical scan address period VSAP and the horizontal scan address period HSAP of the first panel 100 among the plurality of plasma display panels included in the multi-plasma display apparatus are shown. A total of five touch sustain signals TSUS may be supplied to the scan electrode Y and the sustain electrode Z in the scan sustain period SSP therebetween.

Here, as in the case of FIG. 77A, the remote controller 200Q acquires information corresponding to the vertical coordinates of the touch position (for example, information on the light detection time point) in the vertical scan address period VSAP. Thereafter, in the horizontal scan address period HSAP, three times of light generated by the touch sustain signal TSUS having the pattern as shown in FIG. 78B can be detected before acquiring the information corresponding to the horizontal left end of the touch position. have.

For example, as in the case of FIG. 80A, a vertical scan address period VSAP and a horizontal scan address period corresponding to the first panel 100 of a plurality of plasma display panels included in the multi-plasma display apparatus are shown in FIG. In the scan sustain period SSP between the HSAPs, the total touch sustain signals TSUS may be supplied to the scan electrode Y and the sustain electrode Z. For example, the first touch sustain signal TSUS1, the third touch sustain signal TSUS3, and the fifth touch sustain signal TSUS5 are supplied to the scan electrode Y in the scan sustain period SSP, and the sustain electrode ( The second touch sustain signal TSUS2 and the fourth touch sustain signal TSUS4 can be supplied to Z).

Here, the interval between the first touch sustain signal TSUS1 and the second touch sustain signal TSUS2, that is, the time difference Δt50 may be greater than the time difference between two adjacent touch sustain signals TSUS. . For example, the time difference Δt50 between the first touch sustain signal TSUS1 and the second touch sustain signal TSUS2 is the time between the third touch sustain signal TSUS3 and the fourth touch sustain signal TSUS4. It may be larger than the difference Δt 51.

In this case, the time required for the discharge to occur by the second touch sustain signal TSUS2 after the discharge is generated by the first touch sustain signal TSUS1 is generated by the third touch sustain signal TSUS3. Thereafter, it may be longer than the time required for discharge to be generated by the fourth touch sustain signal TSUS4.

It may be greater than a time difference between the touch sustain signal TSUS2 and the third touch sustain signal TSUS3.
