Matrix display device with multiple screen electrodes

摘要

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 xi in which i is an integer such that 1
