First Claim
1. A static interferometric image device comprising:
- a substrate including a first surface, the substrate including a lattice structure defining cavities having substantially the same depth as one another;
an absorber layer formed over the first surface;
a stationary reflective layer formed over the first surface, the reflective layer being vertically spaced apart from the absorber layer; and
a plurality of solidified optical fillers formed in the cavities, the plurality of solidified optical fillers being interposed between the absorber layer and the reflective layer, the plurality of solidified optical fillers being formed of an at least partially transparent material, the plurality of solidified optical fillers being positioned laterally adjacent to one another to form an array over the first surface of the substrate, wherein the plurality of solidified optical fillers are configured to define a pattern of different optical pathlengths between the absorber layer and the reflective layer, based on an image which the static interferometric image device is configured to display.

Abstract
A static interferometric image device including a plurality of solidified liquid layers is formed over a substrate by an inkjet process such that the layers are lateral to one another. In some embodiments, the substrate includes pre-defined cavities, and the liquid layers are formed in the cavities. In other embodiments, the substrate includes a substantially planar, stepped, or continuously transitioning surface, and the solidified liquid layers are formed on the surface. Optical fillers or spacers are provided for defining interferometric gaps between absorbers and reflectors in the display device, based at least partially on an image that the display device is designed to display.
