Abstract

Invention concernant un dispositif électrique d'affichage. Dispositif de visualisation à cristal liquide, avec circuit de commande électronique qui excite des électrodes disposées sur les faces opposées du cristal. Des électrodes concentriques sont divisées en segments; des groupes de barres électrodes formant des secteurs de l'affichage coopèrent, pour chaque secteur, avec un segment intérieur et avec un segment extérieur et les barres électrodes d'un secteur sont reliées dans l'ordre inverse aux barres électrodes du secteur suivant Le circuit électronique choisit un ou des segments dans un secteur requis et modifie en conséquence l'ordre de sélection des barres. Application à l'affichage simultané de trois variables.Invention relating to an electrical display device. Liquid crystal display device, with electronic control circuit which excites electrodes arranged on opposite sides of the crystal. Concentric electrodes are divided into segments; groups of electrode bars forming sectors of the display cooperate, for each sector, with an inner segment and with an outer segment and the electrode bars of one sector are connected in reverse order to the electrode bars of the following sector. electronics chooses one or more segments in a required sector and modifies the order of selection of the bars accordingly. Application to the simultaneous display of three variables.
