Abstract
L'invention concerne un dispositif pour l'affichage de données représentatives de grandeurs. Ce dispositif comprend essentiellement une graduation chiffrée, et un index lumineux généré directement à partir de signaux numériques, cet index pouvant prendre différentes positions le long de ladite graduation. Le dispositif selon l'invention permet l'affichage de grandeurs telles que des valeurs de consigne, des résultats de calcul ou même des valeurs de mesure.
