Abstract: This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display. A pixel circuit used to control one or more display elements of a MEMS display apparatus can include a first output node coupled to a first actuator of a display element and a second output node coupled to a second actuator of the display element. The first output node can be coupled to an actuation interconnect via a first pre-charge switch connected in parallel with a first capacitor. The second output node can be connected to the actuation interconnect via a second pre-charge switch connected in parallel with a second capacitor. Energizing the first output node or the second output node can cause the display element to enter or remain in a first state or a second state, respectively.

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: This disclosure provides systems, methods and apparatus for displaying images. Some such apparatus include a transparent substrate, a display element formed on the substrate, a light blocking elevated aperture layer (EAL) supported over the substrate by an anchor formed on the substrate, and an electrical interconnect disposed on the EAL for carrying an electrical signal to the display element. The electrical interconnect can include one or more of a data voltage interconnect, a scan-line interconnect or a global interconnect. In some implementations, a dielectric layer can separate the electrical interconnect from the EAL. The EAL can include an aperture formed through it that corresponds to the display element. In some implementations, a second electrical interconnect disposed on the substrate can be electrically coupled to a plurality of display elements.

Abstract: Provided are a display device that can suppress occurrence of a color breakup as well as occurrence of a false contour, and a control method therefor. In the display device, a plurality of sub-frame periods forming one frame period are divided into a first group to which sub-frame periods with the same length of light transmission periods belong; and a second group to which sub-frame periods with lengths of light transmission periods shorter than those of the sub-frame periods in the first group and different from each other belong. Further, among the sub-frame periods that belong to the first group, sub-frame periods having the light transmission period increase in number from a middle of the one frame period toward a start point and an endpoint of the one frame period in accordance with an increase of the gray level.

Abstract: This disclosure provides systems, methods and apparatus for providing multi-level multi-state shutter assemblies. The shutter assembly includes at least a first shutter at a first height over a substrate and a second shutter at a second height over the substrate. Both the first shutter and the second shutter can be operated in an open or closed state for passing or partially blocking light propagating through an aperture. In some implementations, the shutter assembly can operate in four states: a fully transmissive state, a fully obstructive state and two partially transmissive states based on the open or closed states of the first and second shutters.

Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.
