Abstract: During a first half of the frame time, the successive odd lines of the first part (10) of the screen are selected simultaneously with the successive even lines of the second part (12) of the screen. During a second half of the frame time, the successive even lines of the first part (10) of the screen are selected simultaneously with the successive odd lines of the second part (12). The information to be displayed during selection is contained in registers (72, 78). The information to be displayed during the following selection are recorded in buffer registers (70, 76) and originate from a source (22) for the odd lines and from a memory (62) for the even lines. This memory (62) records the data to be displayed on the even lines in step with their delivery by the source (22).

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 E1 . . . Ek of one packet Pii'j being connected by switches I1 . . . Ik to a column conductor Cj and to a resistive conductor Rii'j, itself connected between two row conductors Li and Li', with i, i' and j being integers such that i NOTEQUAL i', l
