Abstract
This disclosure provides systems, methods and apparatus for a multi-state shutter assembly. The multi-state shutter assembly can be used in an electronic display. The shutter assembly can include a movable light obstructing component. The shutter assembly also can include first and second actuators configured to move the light obstructing component between three states, including a fully light obstructive state, a substantially transmissive state, and a partially transmissive state. At least one of the three states is a neutral state in which both the first and second actuators are in an unactuated state. The shutter assembly also can include a controller configured to control the first and second actuator to selectively move the light obstructing component into each of the three states.
