example 1
[0078] In the driving method of this example, the waveform of the pulse applied to the S electrode during erasing is as follows Figure 7 shown.
[0079] Figure 6A Indicates the state corresponding to the wall charge on the electrode at the end of the sustain discharge of the previous subfield. In the erasing period, the scan electrode and the data electrode are all placed at 0 (V). At this time, the scan electrode and the data electrode are connected to the S electrode The voltage waveform between them is the same as the voltage waveform applied to the S electrode. The wall charge in the discharge cell can be completely erased, such as Figure 6C shown.

[0082] Figure 6A Indicates the state corresponding to the wall charge on the electrode at the end of the sustain discharge of the previous subfield. In the erasing period, the scan electrode and the data electrode are all placed at 0 (V). At this time, the scan electrode and the data electrode are connected to the S electrode The voltage waveform between them is the same as the voltage waveform applied to the S electrode. The wall charge in the discharge cell can be completely erased, such as Figure 6C shown.
