摘要： A driving method includes generating an address discharge in selected cells out of discharge cells and setting the selected cells to either an emission enable state or a non-emission state in an address period which is set in each subfield period. The driving method also includes generating sustaining discharge in discharge cells being set to the emission enable state by applying at least one discharge sustaining pulse P+ between a scanning electrode and a common electrode constituting each row electrode pair, in a discharge sustaining period following the address period. The driving method also includes decreasing the applied voltage between the scanning electrode and common electrode in steps when a final applied pulse P+ out of the discharge sustaining pulses falls.

摘要： When a sustain discharge corresponding to the display light is repeatedly produced by applying a drive pulse to a PDP which includes a fluorescent layer in the discharge cells, the drive pulse waveform is adjusted in accordance with the total number of sustain discharges. Furthermore, an auxiliary pulse of the same polarity as that of the sustain pulse is applied to the column electrodes in a period from after the application of a final scan pulse in the address process until the application of a leading sustain pulse. A period from the final sustain pulse until the time of the application of the leading pixel data pulse which is applied first in the write address process of the one subfield of the subsequent frame is made 1 millisecond (msec) or more.

摘要： It is an object to provide a driving method of a plasma display panel, whereby a dark contrast can be improved while suppressing an erroneous discharge. In a resetting step in a first unit display period, while a first reset pulse having a predetermined peak electric potential is applied to one of first row electrodes of row electrode pairs formed in the PDP, a second reset pulse having a peak electric potential smaller than that of the first reset pulse is applied to the other of the first row electrodes. In the resetting step in a second unit display period subsequent to the first unit display period, a second reset pulse is applied to each of the one and the other of the first row electrodes.

摘要： When a discharge start voltage takes a normal value under the normal temperature, priming discharge starts at a time t1. In this case, at a time t3 that is later than the time t1 by a predetermined time t, a sustain driver control signal Ssud2 is raised to put a sustain electrode into the floating state to stop the priming discharge. When the discharge start voltage takes a higher value than usual under the high temperature, the priming discharge starts at a time t2. In this case, at a time t4 that is later than the time t2 by the predetermined time t, the sustain driver control signal Ssud2 is lowered to put the sustain electrode into the floating state to stop the priming discharge. With such a configuration, provided is a plasma display device capable of implementing excellent and stable display quality while maintaining constant, even if a discharge start voltage varies, the charge state in display cells after a priming period, and a drive method for such a plasma display device.
摘要翻译：当放电启动电压在正常温度下正常值时，启动放电在时间t 1开始。在这种情况下，在比时刻t 1晚了规定时间t的时刻t 3，维持驱动控制信号Ssud2上升，使维持电极成为浮置状态，停止引发放电。当放电开始电压在高温下比通常值高时，启动放电在时间t 2开始。在这种情况下，在比时刻t 2晚了规定时间t的时刻t 4，维持驱动控制信号Ssud2降低，使维持电极成为浮置状态，停止引发放电。通过这样的结构，即使放电开始电压发生变化，能够实现优异且稳定的显示质量，同时保持恒定的等离子体显示装置，在启动周期之后的显示单元中的电荷状态，以及这种等离子体的驱动方法显示设备。

摘要： Disclosed is a method of driving a plasma display panel. In this method, one field corresponding to one image is divided into a plurality of sub-fields, and at least one second sub-field is arranged after a first sub-field. In the first sub-field, the method comprises a first step of forming wall charges with negative polarity near the scanning electrode and forming wall charges with positive polarity near the common electrode and the data electrode; a second step of adjusting an amount of the wall charges with negative polarity near the scanning electrode and an amount of the wall charges with positive polarity near the common electrode and the data electrode; a third step of generating a writing discharge in a selected display cell of the display cells; a fourth step of generating light emission for display; and a fifth step of erasing a part of the wall charges in the display cell which emits light in the fourth step. In the second sub-field, the method comprises the same steps as the third, fourth and fifth steps. A potential difference between a scanning electrode and a common electrode in each of the fifth steps in the first and second sub-fields is set to be smaller than a potential difference between a scanning electrode and a common electrode in each of the third steps in the first and second sub-fields.
