ABSTRACT:
A matrix display device applicable to liquid crystal displays comprises a display material having an optical property inserted between two insulating walls. On the inner face of one of the walls (1) are arranged n row conductors, m column conductors, p resistive conductors and p.k electrodes grouped into p=m.(n-1) packets of k electrodes each, the electrodes E.sub.1 . . . E.sub.k of one packet P.sub.ii'j being connected by switches I.sub.1 . . . I.sub.k to a column conductor C.sub.j and to a resistive conductor R.sub.ii'j, itself connected between two row conductors L.sub.i and L.sub.i', with i, i' and j being integers such that i.noteq.i', l.ltoreq.i<n, l<i.ltoreq.n and l.ltoreq.i.ltoreq.m. On the inner face of the other wall is placed a counterelectrode. A process for controlling the display device is also disclosed. The invention more particularly applies to liquid crystal display devices.
