Abstract (en)
1. Matrix screen incorporating a layer of material (8) having electrooptical properties, placed between p parallel row electrodes (3) and q parallel column electrodes (4, 6), the row electrodes and column electrodes crossing one another, an image point Xij of the screen being defined by the region of the electrooptical material covered by the row electrode i and column electrode j, in which i and j are integers such that 1 =< i =< p and 1 =< j =< q, characterized in that each row electrode is formed from m first parallel conductive strips (3) of different widths and each column electrode is formed from n second parallel conductive strips (4, 6) of different widths, m and n being positive integers, whereof at least one is >= 2 and in that the material layer (8) is cut over its entire thickness into several zones (10, 12) distributed in matrix-like manner, said zones (10, 12) being defined by the intersection of said first (3) and second (4, 6) conductive strips.
