Meanwhile, a driving method for driving the plasma display panel provided in the display of the image display apparatus will be described below.
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.
10 to 12 illustrate an operation of the plasma display panel in the touch pen mode according to an embodiment of the present invention.
Referring to FIG. 10, in the touch pen mode, at least one of a plurality of subfields forming one frame may be set as a scan subfield.
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). Here, the general subfield is a subfield for video display, that is, video gradation display, and is also referred to as a display subfield in comparison with the scan subfield.
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, in the touch pen mode, when the touch pen type second
Referring to FIG. 11, the scan subfield may include a vertical scan subfield VSSF for detecting the vertical position of the touch position and a horizontal scan subfield HSSF for detecting the 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.
In the vertical scan address period VSAP of the vertical scan subfield VSSF, the touch scan signal TSP descending 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.
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 Y ) And the address electrode X may generate a discharge. In the following description, discharges sequentially generated in the vertical scan address period VSAP are referred to as vertical address discharges as described above.
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.
Meanwhile, the remote controller, for example, the second
For example, in the touch pen mode, it is assumed that the position of the second
In particular, it can be seen that the vertical coordinate of the touch position is Y3 based on the vertical address light sensing timing occurring in the third scan electrode line Y3, and the horizontal address light sensing timing occurring in the second address electrode line X2. Based on this, it can be seen that the horizontal coordinate of the touch position is X2.
The vertical light sensing timing and the horizontal light sensing timing may be calculated based on the scan sustain period SSP, respectively. Accordingly, the coordinate information of the touch position can be obtained simply.
Meanwhile, as in the case of FIG. 11, 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.
On the other hand, unlike the drawing, it is also possible to alternately supply the touch sustain signal TSUS to the scan electrode Y and the sustain electrode Z in the scan sustain period SSP.
The scan sustain period SSP of FIG. 11 may include a synchronous sustain period and an identification sustain period. The scan sustain period may also be referred to as a reference sustain period in other terms.
In FIG. 11, two sync sustain pulses are applied to the scan electrode Y in the sync sustain period, but various examples are possible depending on the setting.
In FIG. 11, an identification sustain pulse is applied to the scan electrode Y after the synchronous sustain pulse, that is, after the second synchronous sustain pulse.
On the basis of such an identification sustain pulse, it is possible to perform vertical coordinate and horizontal coordinate calculation, exactly based on the identification sustain light. For example, as shown in FIG. 12, the vertical coordinate, that is, the Y3 coordinate may be calculated using the time difference between the identification sustain light and the vertical address light corresponding to the Y3 position. Then, the horizontal coordinate, that is, the X2 coordinate can be calculated using the time difference between the identification sustain light and the horizontal address light corresponding to the X2 position.
Of course, in addition to the identification sustain pulse, it is also possible to calculate the horizontal coordinate and the vertical coordinate by further utilizing the synchronous sustain pulse.
