Title:
PLASMA DISPLAY PANEL DRIVING METHOD AND PLASMA DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/059735
Kind Code:
A1
Abstract:
A plasma display panel driving method and a plasma display device are provided for
making it possible to reduce the occurrence of an initial bright spot immediately after
driving a plasma display panel so that display quality can be improved. To this
end, the driving method sets a plurality of subfields in one field that each have
an initializing period, a writing period and a maintaining period, wherein the
one field period is configured to include at least one of the subfields that applies
a gradually rising-up slope waveform voltage in the initial period to a scanning
electrode and the slope waveform voltage first applied to the scanning electrode
from the commencement of the driving of the plasma display is generated with a
gentler slope than the other slope waveform voltage.
