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.
