Abstract
The method is for controlling a plasma matrix screen, including sequential selection of rows of the matrix and, for a selected row, deselection of a plurality of columns of the matrix which were previously selected during the selection of a previous row. To avoid excessive steepness of the falling edges of the column potentials, the previously selected columns are non-simultaneously deselected.
