Active matrix for liquid-crystal displays

The invention relates to an active matrix for liquid-crystal displays, including several image elements, several address buses (1-1, 1-2, 1-3,..., 1-n), and several data buses (2-1, 2-2, 2-3, 2-4,..., 2-m) perpendicular to the address buses, each address bus comprising two auxiliary address buses (1...

Beschreibung
Zusammenfassung:	The invention relates to an active matrix for liquid-crystal displays, including several image elements, several address buses (1-1, 1-2, 1-3,..., 1-n), and several data buses (2-1, 2-2, 2-3, 2-4,..., 2-m) perpendicular to the address buses, each address bus comprising two auxiliary address buses (1-1', 1-1''; 1-2', 1,2''; 1-3', 1-3'';...; 1,-n', 1-n'') spaced apart from one another, and each data bus comprising two auxiliary data buses (2-1', 2-1'', 2-2', 2-2''; 2-3', 2-3''; 2-4', 2-4'';...; 2-m', 2-m'') spaced apart from one another. Each image element comprises two display electrodes (4', 4''); a first switching means (3', 3'') mounted between each display electrode and a first of the two auxiliary address buses and a corresponding data bus; and a second switching means (3, 3) mounted between each display electrode and a second of the two auxiliary address buses and the corresponding data bus; each auxiliary data bus being separated from the other by at least one display electrode. L'invention concerne une matrice active pour affichages à cristaux liquides, comportant plusieurs éléments d'images, plusieurs bus d'adresses (1-1, 1-2, 1-3,..., 1-n), et plusieurs bus de données (2-1, 2-2, 2-3, 2-4,..., 2-m) perpendiculaires aux bus d'adresses, chaque bus d'adresses comprenant deux bus auxiliaires d'adresses (1-1', 1-1"; 1-2', 1-2"; 1-3', 1-3";...; 1-n', 1-n") espacés l'un de l'autre, et chaque bus de données comprenant deux bus auxiliaires de données (2-1', 2-1"; 2-2', 2-2"; 2-3', 2-3"; 2-4', 2-4";...; 2-m', 2-m") espacés l'un de l'autre. Chaque élément d'image comprend deux électrodes d'affichage (4', 4"); un premier moyen de commutation (3I , 3I I ) monté entre chaque électrode d'affichage et un premier des deux bus auxiliaires d'adresses et un bus de données correspondant; et un second moyen de commutation (3I I I , 3I V ) monté entre chaque électrode d'affichage et un second des deux bus auxiliaires d'adresses et le bus de données correspondant; chaque bus auxiliaire de données étant séparé de l'autre par au moins une électrode d'affichage.
