摘要： Systems, methods and apparatus are provided for controlling launch effects of movable layers in electromechanical systems (EMS) devices. First and second EMS devices with first and second step creating layers are positioned over a substrate and spaced, by different gaps, from the movable layers of the EMS devices. The movable layers of the first and second EMS devices include steps having different heights and/or different edge spacing from the center of an anchoring region of each EMS device. The different steps can provide different launch effects for different EMS devices, and if the same thickness of sacrificial material is used for the different devices, the different launch effects can be responsible for different gap heights in the unbiased conditions.

摘要： This disclosure provides systems, methods and apparatus for reducing image artifacts that arise when a display is exposed to sunlight over time. Various implementations disclosed herein can be implemented to prevent charge injection from inducing a negative offset voltage shift for display elements in the display. In one aspect, a buffer layer is applied to block electrons from being photoelectrically ejected from a movable reflective layer of a display element and into a stationary optical stack of the display element.

摘要： This disclosure provides systems, methods and apparatus for electromechanical systems displays. In one aspect, the display can include a plurality of electromechanical display elements including a first set of electromechanical display elements and a second set of electromechanical display elements. Each electromechanical display element can include a common electrode and a segment electrode. Each of the segment electrodes of the first set of electromechanical display elements can have a first area located under the common electrodes of the first set. Each of the segment electrodes of the second set of electromechanical display elements can have a second area smaller than the first area located under the common electrodes of the second set. In some implementations, an actuation voltage of each electromechanical display element of the first set is approximately the same as an actuation voltage of each electromechanical display element of the second set.

摘要： Systems, methods and apparatuses reduce stress and/or reduce stiffness in a movable layer of an electromechanical systems (EMS) device. Stress or stiffness can be reduced by including one or more compressive stress layers to compensate for the tensile stress exhibited by other layers of the movable layer. The movable layer can include a dielectric core with a first tensile stress layer and a first compressive stress layer on a first side of the dielectric core, and a second tensile stress layer and a second compressive stress layer on a second side of the dielectric core.
