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.
