Title:
PLASMA DISPLAY PANEL DRIVING METHOD AND PLASMA DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/142254
Kind Code:
A1
Abstract:
A plasma display panel driving method and a plasma display apparatus wherein the
number of write errors can be further reduced and excellent picture quality can
be achieved. According to the plasma display panel driving method, a plurality of
scan electrodes is divided into two scan electrode groups of odd and even rows, and
the write interval of each of subfield intervals is divided into first and second
sub-intervals (Ta,Tb) to which the respective scan electrode groups are assigned.
During each of the sub-intervals (Ta,Tb), the scan electrodes are sequentially
selected in such a manner that a selection potential (Vb) and a first non-selection
potential (Vs) are applied to the scan electrodes of the scan electrode groups.
A write potential (Vw) is applied to data electrodes (D1-Dm) to be selected in
synchronism with the selection of the scan electrodes. It is arranged that a
time (ta) in which the selection potential (Vb) is applied during the first sub-interval
(Ta) be shorter than a time (tb) in which the selection potential (Vb) is applied
during the second sub-interval (Tb). During the first sub-interval (Ta), a
second non-selection potential (Vx) higher than the first non-selection potential
(Vs) is applied to the scan electrodes (SCNb) of scan electrode groups assigned
to the second sub-interval (Tb).
