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.
