  • Publication number: 20030107327
    Abstract: 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, said column having a different capacitance (C2) depending on whether or not the neighbouring columns are selected, each drive unit (14′) comprising first means (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 means (T2, 28) for discharging said capacitance in a second predetermined time interval during the high-to-low transition of the voltage window, the second means being controlled on the basis of an estimation of said capacitance obtained from data (Qi−1, Q i+1?) indicating whether or not the neighbouring columns of said columns have been selected.

  • Publication number: 20030057852
    Abstract: The invention concerns a method for controlling a matrix plasma panel cells, consisting of cells (4) arranged at the intersections of lines (6) and columns (8), comprising a step which consists in sequentially applying to each line an activating potential and, during a line activation, in applying an activation potential to selected columns, wherein while a line is being activated, the selected columns are activated non-simultaneously.
