Method and apparatus for driving plasma display panel operating with middle discharge mode in reset period

A method for driving a plasma display panel includes applying an erasing pulse, a reset pulse and a scan pulse respectively in each of an erasing period, a reset period and a scan period. In a reset period, a reset pulse with a waveform of a sloped ramp pulse is applied to the scan electrode. The sl...

Zusammenfassung:A method for driving a plasma display panel includes applying an erasing pulse, a reset pulse and a scan pulse respectively in each of an erasing period, a reset period and a scan period. In a reset period, a reset pulse with a waveform of a sloped ramp pulse is applied to the scan electrode. The sloped ramp pulse induces a discharge between the scan electrode and the address electrode in the middle of the period while the pulse voltage increases. This prevents extremely high discharges between the scan electrode and the address electrode and improves the contrast of the display. An apparatus that implements such method is also disclosed.
