Abstract: This disclosure provides systems, methods and apparatus for dissipating charge buildup within a display element with a conductive layer. The conductive layer is maintained in electrical contact with a fluid within the display element. The fluid, in turn, remains in contact with light modulators within the display elements. Any charge buildup that may be caused by the filling of the fluid during fabrication of the display device, or during operation of the light modulators can be dissipated by the conductive layer. Thus, by dissipating the charge buildup, the conductive layer reduces or eliminates electrostatic forces due to the charge buildup that may affect the operability of the light modulators. The display can include conductive spacers in an active display region of the display and a spacer-free region that allows the substrates to deform while retaining an electrical connection between the conductive layer and the spacers in the active display region.

Abstract: Systems, methods and methods of manufacture for, among other things, a MEMS display that has a substrate with a first and a second array of apertures. The first and second arrays are, typically, formed on the substrate so that the arrays are adjacent and define a field boundary line that may extend between the two arrays and along a width of the substrate. In at least one array, the apertures that are proximate the field boundary line are placed at locations on the substrate to reduce differences in luminance between one portion of the display and another portion of the display.

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 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.
