First Claim
Patent Images
1. A device, comprising:
- a substrate; and
an array of reflective elements arranged on the substrate to form at least a portion of a mirror surface that specularly reflects incident light in at least one wavelength band, each element comprising;
a partially reflective layer; and
a substantially reflective layer separated from the partially reflective layer by a predetermined space, wherein the space defines an interferometric cavity;
wherein one or more of the elements are configured to be selectably reflective.

Abstract
A specular interferometric modulator array is configured to be at least partially selectably reflective. As such, the array forms a mirror surface having the capability of displaying information to the user while simultaneously being used as a specular mirror. The displayed information may be based on information from an external source, may be programmable, and may be based on user input.
