Abstract:
1. A circuit for controlling an array of cells of a plasma screen, each cell of the array of cells being disposed at a corresponding intersection of one of a plurality of lines and one of a plurality of columns, comprising: a plurality of line control blocks, each line control block configured to apply a line activation signal to a corresponding one of the plurality of lines; and a plurality of column control blocks, each column control block configured to apply a column activation signal to a corresponding one of the plurality of columns, and each column control block comprising a delay device adapted to control application of the activation signal to the column corresponding to the control block, a first of the plurality of column control blocks configured to provide a first delay in applying the activation signal to the column of the plasma screen corresponding to the first control block and a second of the plurality of column control blocks configured to provide a second delay in applying the activation signal to the column of the plasma screen corresponding to the second control block, the first delay being different than the second delay.
