Abstract
Embodiments include methods and devices for controlling the spectral profile and color gamut of light produced by an interferometric display. Such devices include illuminating a display with selected wavelengths of light. Embodiments also include a display comprising separate sections that output different predetermined colors of light. Other embodiments include methods of making the aforementioned devices.

A display comprising:
- at least one interferometric modulator configured to selectively reflect light having a characteristic color, said modulator having a spectral response characterized by a first spectral peak;
- and
- at least one color filter having a spectral response characterized by a second spectral peak, said filter configured to filter said selectively reflected light to output light characterized by a third spectral peak,
- wherein said third spectral peak has a spectral width that is narrower than the spectral width of the first spectral peak.
