ABSTRACT:
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.
