ABSTRACT:
The invention relates to a matrix display device with a plurality of sets of electrodes as well as to the process for controlling the same.
The device comprises two insulating walls and by a material having a plurality of zones distributed in matrix-like manner and inserted between a first system of electrodes covering one of the two walls and defining p control columns and a second system of electrodes covering the other wall, constituted by parallel conductive strips, and defining q control lines, the column x.sub.i in which i is an integer such that 1.ltoreq.i.ltoreq.p and row y.sub.j in which j is an integer such that 1.ltoreq.j.ltoreq.q defining a zone x.sub.i y.sub.j of the material. The first system is constituted by a solid layer of electrodes and n sets of electrodes, which are electrically insulated from one another. The electrodes of this system being grouped in such a way that each group of electrodes corresponds to a single control row.
