Meanwhile, referring to FIG. 10, the low level section of the timing signal Sf corresponds to the section of the lower level, not the peak section of the detected optical signal S IR .

For example, a falling edge and a rising edge of the timing signal Sf of FIG. 10C may be calculated to set the average value to a low level. That is, it is possible to set the intermediate section between the falling edge and the rising edge to a low level.

Meanwhile, a driving method for driving the plasma display panel included in the display of the image display apparatus will be described below with reference to FIG. 11.
In the plasma display panel, the unit frame for implementing the gray level of the image may include a plurality of subfields.
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.
Alternatively, at least one subfield of the plurality of subfields of the frame may further include a reset period for initialization.
FIG. 11 shows an example of a driving waveform used in a normal mode other than the touch pen mode and the touch pen mode. In the touch pen mode, at least one of the plurality of subfields of the frame may be set as a scan subfield for a touch. This will be described in detail below.
11 and 12, in the touch pen mode, at least one of a plurality of subfields constituting one frame may be set as a scan subfield Scan SF.
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 pen 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 in the case of FIG. 6, when the touch pen
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 pen 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.
Meanwhile, although only the case where the vertical scan subfield is disposed before the horizontal scan subfield in one frame, the figure may be also 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.
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 set-up period SSU2 of the scan reset period SRP, the third scan up ramp signal SRU3 is supplied to the scan electrodes, and then, in the second scan set-down period SSD2, the third scan down ramp is supplied to the scan electrodes. 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.
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.
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.
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). In the following description, discharges sequentially generated in the vertical scan address period VSAP are referred to as vertical address discharges as described above.
For example, as illustrated in FIG. 13A, the touch scan signals TSP may be sequentially supplied to the plurality of scan electrodes Y1 to Yn. As a result, as shown in FIG. 13B, the scan electrodes Y may be provided. ) And the address electrode X, vertical address discharge may occur sequentially for each scan electrode line Y.
That is, 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 line Y1, and Subsequently, 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 line Y2.
Next, the reset period of the horizontal scan subfield HSSF 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.
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.
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 Y And discharge may occur between the sustain electrode Z and the address electrode X. 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. 15A, the touch data signal TDP may be sequentially supplied to the plurality of address electrodes X1 to Xm, and as a result, the scan electrode (see FIG. 15B) may be applied. Horizontal address discharge may occur sequentially between the address electrode lines X, between Y) and the address electrode X, or between the sustain electrode Z and the address electrode X.
That is, 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 line X1. Thereafter, 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 line X2.
Meanwhile, the remote controller described above in detail, for example, the
For example, in the touch pen mode, it is assumed that the position of the
In particular, it can be seen that the vertical coordinate of the touch position is Y3 based on the vertical address light sensing timing Tk3 generated in the third scan electrode line Y3, and the horizontal address generated in the second scan electrode line X2. Based on the light detection timing T02, it can be seen that the horizontal coordinate of the touch position is X2.
The vertical light sensing timing Tk3 and the horizontal light sensing timing T02 may be calculated based on the scan sustain period SSP, respectively. Accordingly, the coordinate information of the touch position can be obtained simply. Coordinate information acquisition is described in detail with reference to FIG. 16.
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.
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. .
Referring to FIG. 17, the driving waveforms Vx and Vy of FIG. 17 briefly illustrate a waveform applied to a scan electrode and a waveform applied to an address electrode in the scan subfield Scan SF of FIG. 12. That is, the driving waveforms in the vertical scan subfield VSSF, the scan sustain period SSP, and the horizontal scan subfield HSSF in Fig. 12 are briefly shown.
The scan sustain period SSP of FIG. 12 may include the synchronous sustain period Tss and the identification sustain period Tis of FIG. 17. The scan sustain period (SSP) may also be referred to as a reference sustain period in other terms.
In FIG. 17, four sync sustain pulses are applied to the scan electrode Y in the sync sustain period Tss, but various examples are possible depending on the setting. In FIG. 17, an identification sustain pulse is applied to the scan electrode Y after the synchronous sustain pulse, that is, after the fourth synchronous sustain pulse.
For example, as shown in FIGS. 12 and 16, two sync sustain pulses may be applied to the scan electrode Y and the sustain electrode, and an identification sustain pulse may be further applied to the scan electrode Y. have.
As described above, when the scan pulse Tsp is applied to the scan electrode Y in the vertical scan subfield VSSF, vertical address discharge occurs in the corresponding discharge cell. In addition, when four synchronous sustain pulses are alternately applied to the scan electrode Y and the sustain electrode Z in the synchronous sustain period Tss, eight synchronous sustain discharges occur. In addition, in the identification sustain period Tis, when an identification sustain pulse is applied to the scan electrode Y, one identification sustain discharge occurs. When the data signal TDP is applied to the address electrode X in the horizontal scan subfield HSSF, one horizontal address discharge occurs.
In the embodiment of the present invention, an example of a method for obtaining coordinate information will be described on the assumption that the
Here, Ty can represent the period between the scan signal application period in the discharge cell in which the
That is, when Ty is detected, the fixed offset Ty offset and T scan _y_ width Using, it is possible to calculate the final vertical coordinates. Ty can be calculated using the timing difference between the 1st vertical address discharge in a specific discharge cell and the 7th synchronous sustain discharge.
Here, Tx may represent a period between one identification sustain pulse application period and a data signal application period in the discharge cell in which the
That is, when Tx is detected, Tx offset and T scan _x_ width are fixed values. Using, it is possible to calculate the final horizontal coordinates. Tx can be calculated using the timing difference between one identification sustain discharge and the horizontal address discharge in a specific discharge cell.
Comparing
On the other hand, unlike the drawing, Tx offset And Tx offset Can be set by various methods. For example, when the starting point of Tx is the point of time when the fourth synchronous sustain pulse is applied, the Tx offset It may also mean a period between the time of applying the synchronous sustain pulse to the start of the horizontal scan subfield (HSSF).
On the other hand, the
On the other hand, the period between the fourth synchronous sustain pulse application time and the identification sustain application time point in the drawing is set to Tm, and when the
The present invention can be applied without being limited to the number of synchronous sustain pulses applied in the synchronous sustain period Tss.
For example, in the synchronous sustain period Tss, two synchronous sustain pulses may be alternately applied to the scan electrode Y and the sustain electrode Z. FIG.
In this case, two synchronous sustain pulses applied to the sustain electrode may serve as second and fourth synchronous sustain pulses among the synchronous sustain pulses applied to the scan electrode of FIG. 17.
Referring to FIG. 18A, when the
According to the exemplary embodiment of the present invention, the
At this time, in order to distinguish which discharge cell of which panel among the plurality of plasma display panels detects infrared light, it is possible to set the period between the synchronization sustain pulse and the identification sustain pulse differently for each panel as shown in FIG. 18B. Do.
That is, the waveform shown in FIG. 18B is applied to the scan electrode Y in the scan sustain period SSP, and the
On the other hand, in order to distinguish the panel, various settings are possible in addition to the period division.
FIG. 18C illustrates that the pulse widths W1 and W2 of the identification sustain are different for the
18C and 18D have different pulse widths or pulse sizes in order to distinguish them from different panels, so that the length and intensity of the actual identification sustain discharge section are changed. Accordingly, in the
