ABSTRACT:
The invention relates to a matrix display provided with a coupling compensation device between the rows and columns. The matrix display comprises a material, whose optical characteristic can be modified, said material being interposed between a group of row electrodes and a group of column electrodes, whose intersections X.sub.i Y.sub.j are the addressable points of the matrix display. It also comprises at least one compensation electrode and means for raising said compensation electrode to an appropriate potential for eliminating parasitic charges appearing on the row electrodes.
