Initialization
Fig. G
To clear any remaining electric charge into the pixel, trape-
zoid voltage is applied between the scan and sustain elec-
trodes.
Plasma discharge is started but the discharge become small
gradually.
Then any electric charge is cleared.

Data Pulse which is positive polarity is input to data electrode
and Scan pulse which is negative polarity is input to scan
electrode simultaneously.
That means sum of data and scan pulses voltage is applied
between two electrodes as discharge start voltage.
Discharge is started into the pixel and gas is ionized.
During discharging ion is charged on the scan electrode side
and electron is charged on data electrode side.
