Title:
PLASMA DISPLAY PANEL DRIVE METHOD AND PLASMA DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/099891
Kind Code:
A1
Abstract:
A plasma display panel drive method and a plasma display device for displaying
an image with a high quality by stabilizing the initializing electric discharge.
In the plasma display panel drive method, one field period is composed of sub-fields,
in the initialization period of at least one sub-field, all-cell initialization
for initializing all the discharge cells for displaying an image, the sub-fields
are so controlled that a write operation is performed in the discharge cells or
any write operation is not performed, a control is made so that there are a plurality
of predetermined sub-fields during which a write operation is performed only
when a write operation is performed in at least one sub-field after the all-cell
initialization thereby to display gradation, an abnormal charge erasing period
during which a rectangular waveform voltage is applied to scan electrodes (SC1
to SCn) is provided after the initialization period of at least one sub-field
out of the predetermined sub-fields.
