METHOD OF DRIVING PLASMA DISPLAY PANEL

摘要

A method of driving a plasma display panel capable of improving the contrast with reduced power consumption while suppressing a pseudo-contour. In each of a plurality of subfields divided from a display period of one field, a pixel data writing stage is executed for selectively erasing and discharging wall charges formed in discharge cells in accordance with pixel data to set the discharge cells to light emitting cells and non-light emitting cells, and a light emission sustaining stage is executed for allowing the light emitting cells to sustain light emission for a time corresponding to weighting for each subfield. Also, a simultaneous resetting stage is provided for simultaneously resetting or discharging all discharge cells to form wall charges only in the first subfield in a group of subfields including at least two mutually consecutive subfields, and the erasing discharge is performed only in the pixel data writing stage in any subfield in the group of subfields.
