The invention concerns a drive circuit for a plasma panel consisting of
cells arranged at the intersections of lines and columns, comprising, for
each column of the panel, a column drive unit (14') for selecting the
column by applying a voltage window, the column having a different
capacitance (C2) depending on whether or not the neighboring columns are
selected, each drive unit (14') comprising first elements (T1, C, CS1)
for changing the capacitance in a first predetermined time interval
during the low-to-high transition of the voltage window, and second
elements (T2, 28) for discharging said capacitance in a second
predetermined time interval during the high-to-low transition of the
voltage window, the second elements being controlled on the basis of an
estimation of the capacitance obtained from data (Qi-1, Qi+1) indicating
whether or not the neighboring columns of said columns have been
selected.
