Abstract
(EN)
A light modulator device includes a first electrical conduit, a second electrical conduit electrically isolated from the first conduit, a first display element, and a second display element. The first display element is in an actuated state when a voltage difference between the first conduit and the second conduit has a magnitude greater than a first actuation voltage and is in a released state when the voltage difference has a magnitude less than a first release voltage. The second display element is in an actuated state when the voltage difference has a magnitude greater than a second actuation voltage and is in a released state when the voltage difference has a magnitude less than a second release voltage. Either the actuation voltages are substantially equal and the release voltages are different, or the actuation voltages are different and the release voltages are substantially equal.

L'invention concerne un dispositif modulateur optique comprenant un premier conduit électrique, un deuxième conduit électrique, isolé électriquement du premier conduit, un premier élément d'affichage, et un deuxième élément d'affichage. Le premier élément d'affichage est dans un état actionné lorsqu'une différence de tension entre le premier conduit et le deuxième conduit a une magnitude supérieure à une première tension d'actionnement et est dans un état relâché lorsque la différence de pression a une magnitude inférieure à une première tension de relâchement. Le deuxième élément d'affichage est dans un état actionné lorsque la différence de tension a une magnitude supérieure à une deuxième tension d'actionnement et est dans un état relâché lorsque la différence de tension a une magnitude inférieure à une deuxième tension de relâchement. Soit les tensions d'actionnement sont sensiblement égales et les tensions de relâchement sont différentes, soit les tensions d'actionnement sont différentes et les tensions de relâchement sont sensiblement égales.
