摘要： Discharge for detecting the position coordinates of an electronic pen is caused stably, and the position coordinates are detected accurately. For this purpose, in a driving method of an image display device, an image display subfield, a y-coordinate detection subfield, and an x-coordinate detection subfield are included in one field. In the x-coordinate detection subfield, an x-coordinate detection waiting period is set in which a voltage higher than an x-coordinate detection voltage is applied to the scan electrodes and a voltage lower than the voltage of x-coordinate detection pulses is applied to the data electrodes. After the x-coordinate detection waiting period, the x-coordinate detection voltage is applied to the scan electrodes, and the x-coordinate detection pulses are sequentially applied to the data electrodes.

摘要： In a plasma display apparatus, contrast is enhanced and a stable address discharge is caused. For this purpose, one of a forced initializing operation and a selective initializing operation is performed in initializing periods. A specified-cell initializing subfield and a selective initializing subfield are set in one field. In the specified-cell initializing subfield, the forced initializing operation is performed on specified discharge cells and the selective initializing operation is performed on the other discharge cells. In the selective initializing subfield, the selective initializing operation is performed on all the discharge cells. In the selective initializing period, a down-ramp waveform voltage is applied to the scan electrodes and a positive voltage is applied to the data electrodes. In the selective initializing subfield, based on the load calculated in the address period of the immediately preceding subfield, the minimum voltage of the down-ramp waveform voltage is controlled.

摘要： Image display quality in the plasma display apparatus can be enhanced by allowing a stable address operation. For this purpose, the plasma display apparatus includes a scan electrode driver circuit. The scan electrode driver circuit generates driving voltages to be used in a subfield method and applies the driving voltages to scan electrodes. At the end of each sustain period, the scan electrode driver circuit performs the following operation. The scan electrodes are applied with a first ramp waveform voltage that rises from a base electric potential to a first electric potential. Subsequently, the electric potential of the scan electrodes is set to a second electric potential equal to or lower than the first electric potential.

摘要： Sharp contrast is achieved while the driving time in displaying a 3D image on a plasma display panel is shorted. For this purpose, an all-cell initializing subfield for applying up-ramp waveform voltage and down-ramp waveform voltage to a scan electrode in the initializing period is set as the first subfield of one field. The plasma display panel is driven by one of 3D drive and 2D drive. A gradient of at least one of the up-ramp waveform voltage and the down-ramp waveform voltage in the all-cell initializing period during the 3D drive is set to be steeper than a gradient of the one waveform voltage in the all-cell initializing period during the 2D drive. A shutter opening/closing timing signal is generated so that both of a right-eye timing signal and a left-eye timing signal are in the OFF state in the all-cell initializing period during the 3D drive.

摘要： Stable address discharge is caused even in a plasma display panel where the definition is enhanced and the screen is enlarged. For this purpose, in a driving method of a plasma display panel, the image display region of the panel is divided into a plurality of partial display regions each of which includes a plurality of consecutively arranged scan electrodes. In each partial display region, a sequential address operation of sequentially applying scan pulses to the scan electrodes based on the arranging sequence of the scan electrodes on the panel is performed in the address period. To the scan electrode to which a scan pulse is to be firstly applied in the address period, a scan pulse of which the pulse width is set longer than that of the scan pulse to be applied to the other scan electrodes is applied.

摘要： A stable address discharge is caused by preventing an increase in the necessary scan pulse voltage (amplitude), and thereby achieves high image display quality. For this purpose, the image display area of a plasma display panel is divided into a plurality of regions, and a partial light-emitting rate is detected in each region. The partial light-emitting rate in a current subfield is set as a first partial light-emitting rate. The partial light-emitting rate used for magnitude comparison between the partial light-emitting rates in a subfield identical with the current subfield in a field immediately preceding the field to which the current subfield belongs to is set as a second partial light-emitting rate. The absolute value of the difference between the first partial light-emitting rate and the second partial light-emitting rate is calculated in each region. In the region where the value is equal to or larger than a light-emitting rate threshold value, the first partial light-emitting rate is used for the magnitude comparison between the partial light-emitting rates in the current subfield. In the region where the value is smaller than the light-emitting rate threshold value, the second partial light-emitting rate is used for the magnitude comparison between the partial light-emitting rates in the current subfield.

摘要： A stable address discharge is caused to enhance the image display quality. For this purpose, a plasma display panel, a scan electrode driving circuit, and a partial light-emitting rate detecting circuit are provided. The scan electrode driving circuit performs an address operation by applying a scan pulse to scan electrodes in address periods.

In a predetermined subfield where the number of sustain pulses is smaller than the number of sustain pulses in the immediately preceding subfield, the scan electrode driving circuit changes the order of applying the scan pulse to the scan electrodes, according to the partial light-emitting rates in the immediately preceding subfield.
