Driving circuit for a plasma display panel performing a stable sustain discharge by reducing effects from adjacent display cells

摘要

A driving circuit (102, 105) is provided for a plasma display panel in which a display cell including a first electrode (Yn) and a second electrode (Xn) is selected to light up. The driving circuit applies a first voltage Vs1 to the first electrode and a second voltage Vs2 to the second electrode adjacent to the first electrode to cause a sustain discharge between the first and second electrodes. The driving circuit generates a sustain discharge voltage such that, during the sustain discharge between the first and second electrcdes, an applied voltage Vc to a third electrode adjacent to the first electrode opposite to the second electrode falls within a range Vs2 ≦ Vc < Vs1, and, in this case, when a display cell including the third electrode is selected to light up, the polarity of a wall charge formed on the third electrode becomes positive.
