    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 translation: 本公开提供了用于为快门组件提供多个电介质涂层的系统，方法和装置。 多个电介质涂层包括外部电介质涂层和一个或多个内部电介质涂层。 外部电介质涂层具有低于一个或多个内部电介质涂层的电阱密度的电阱密度。 较低的电子阱密度减少了在快门组件的各个表面上积累的电荷量。 电荷累积的减少也减少了可能导致快门组件错误操作的静电力。

    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.

    Abstract: This disclosure provides systems, methods and apparatus for shutter-based EMS light modulators controlled by electrode actuators that include a compliant inner beam electrode positioned between a movable beam electrode and a fixed beam electrode. A first voltage is applied to the movable beam electrode, and a sufficiently different voltage is applied to one of the compliant beam electrode and the fixed outer beam electrode. During actuation, the movable beam electrode is drawn towards the compliant inner beam electrode, while the combination of the movable beam electrode and the compliant inner beam electrode are further drawn to the fixed beam electrode.

    Abstract: This disclosure provides systems, methods and apparatus for incorporating tip-gap adjustment features (TGAF) in actuators of shutter assemblies. The TGAF are incorporated into a drive beam of the actuator during the formation of the shutter assembly over a mold. The TGAF are configured such that they develop a mechanical stress or stress gradient. When the shutter assembly is released from the mold, the stress or stress gradient in the TGAF bend the drive beam such that a tip-gap between the drive beam and a load beam of the actuator is reduced. The reduced tip-gap, in turn, reduces an actuation voltage needed to actuate the shutter assembly.

    Abstract: An electromechanical device includes a movable body that is movable along an axis of a direction of motion. The device also includes an actuator beam and a compliant support beam arranged to support the movable body. The compliant support beam includes a first end connected to an anchor and an actuating portion extending from the anchor and in a direction that is transverse to the axis of the direction of motion and away from the anchor. The actuating portion is also arranged adjacently and spaced apart from the actuator beam. The compliant support beam also includes a connector portion that is contiguous with the actuating portion and coupled to the movable body. The connector portion extends at least partially back toward the anchor while being arranged adjacently and spaced apart from the actuating portion.
