Abstract: This disclosure provides systems, methods and apparatus for modulating light to form an image on a display. A light modulator in the display may include a substrate, a shutter, a first actuator and a second actuator. The shutter can be configured to selectively obstruct an optical path through the substrate. The first actuator can be configured to move the shutter in a first direction along a first axis in a plane substantially parallel to a plane defined by the substrate, thereby moving the shutter from a first state to a second state. The second actuator can be configured to move the shutter in a second direction along a second axis. The second axis can be substantially orthogonal to the first axis and also within a plane parallel to the substrate. In some implementations, moving the shutter along the second axis moves the shutter into a third state.

Abstract: This disclosure provides systems, methods and apparatus for providing multiple dielectric coatings for a shutter assembly. The multiple dielectric coatings include an outer dielectric coating and one or more inner dielectric coatings. The outer dielectric coating has an electrical trap density that is lower than electrical trap densities of the one or more inner dielectric coatings. The lower electrical trap density reduces the amount of charge buildup over various surfaces of the shutter assembly. This reduction in charge buildup also reduces electrostatic forces that may cause incorrect operation of the shutter assembly.

Abstract: Systems, apparatuses and methods are provided for increasing the aperture ratio of a display by increasing the total travel distance of respective light modulating bodies in a display while maintaining fast switching speeds. Increasing the total travel distance allows for a larger aperture ratio in a display, which provides greater power savings and increased display brightness. The total travel distance of a light modulating body includes the distance the body travels from an open position to a closed position, and vice-versa. In one example, the travel distance of a light modulating body (e.g., any of the light modulators as described above) is asymmetric: from a neutral position, the body travels a greater distance in a first direction than in a second direction.
