Abstract: An electro-optic medium comprises at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli. The medium allows for development of differing colors in differing areas of the medium, thus allowing formation of intrinsic color within differing areas of a single layer of the same electro-optic medium. In an electrophoretic medium, the colors may be developed within the electrophoretic particles or within the fluid in which the particles are dispersed.

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.

The second offset lowers the output of the driver circuit to prevent the excess optical output of the transmitter optical module.
