Method and apparatus for driving plasma display panel using selective write and selective erase

A method of driving a plasma display panel that selects cells in use of selective writing sub-fields and selective erasing sub-fields arranged within one frame period, sustains a discharge for the selected cells in use of a sustaining pulse, and has a plurality of scanning electrodes, a plurality of sustaining electrodes and a plurality of address electrodes, comprising steps of:

• setting an erasing initialization pulse with a pulse width wider than the sustaining pulse;
• and
• applying the erasing initialization pulse to the plasma display panel before the selective erasing sub-field.

A method of driving a plasma display panel that selects cells in use of selective writing sub-fields and selective erasing sub-fields arranged within one frame period, sustains a discharge for the selected cells in use of a sustaining pulse, and has a plurality of scanning electrodes, a plurality of sustaining electrodes and a plurality of address electrodes, comprising steps of:

• setting an erasing initialization pulse with a voltage higher than the sustaining pulse;
• and
• applying the erasing initialization pulse to the plasma display panel before the selective erasing sub-field.

A driving apparatus of a plasma display panel that selects cells in use of selective writing sub-fields and selective erasing sub-fields arranged within one frame period, and has a plurality of scanning electrodes, a plurality of sustaining electrodes and a plurality of address electrodes, comprising:

• a first scanning circuit for selecting an on-cell by applying a first scanning voltage to a scanning electrode to generate a writing discharge in the selective writing sub-field;
• and
• a second scanning circuit for selecting an off-cell among the on-cells by applying a second scanning voltage, which is different from the first scanning voltage, to the scanning electrode to generate an erasing discharge in the selective erasing sub-field.
