Abstract
An AC-type PDP in which adjacent two scanning lines share one sustain discharge electrode and a discharge separator for separating surface discharges in the adjacent scanning lines is driven as follows. In a writing period (O ), the voltages at odd-numbered sustain discharge electrodes (J ) are set to the voltage (H) and the voltages at even-numbered sustain discharge electrodes (J ) are set to the voltage (M). At selection of odd-numbered scanning lines (S ) in descending order, when image data (W) according to the scanning line (S ) is applied to an address electrode ( ), the voltages at the sustain discharge electrodes (J and J ) are changed to the voltages (M and L), respectively. In a polarity reverse period (RV), after a voltage (Voff) is applied to all the address electrodes ( ) and the voltages at the sustain discharge electrodes (J and J ) are changed from the voltage (M) to the voltages (L and H), respectively, the voltages at the sustain discharge electrodes (J and J ) are returned to the voltage (M). In a writing period (E ), even-numbered scanning lines (S ) are selected in ascending order conversely to the order in the writing period (O ). With this operation, it is possible to enhance a display contrast, reduce a reactive power and stabilize a writing discharge.
