Method and device for reflective display with time sequential color illumination

A method of manufacturing an interferometric light modulating device, comprising:

• providing a plurality of pixel elements, each pixel element comprising at least one interferometric light modulator having a spectral response that includes two or more reflectance peaks in the visible spectrum;
• and
• providing a light source configured to selectively illuminate said plurality of pixel elements with light having one or more spectral peaks substantially overlapping said two or more reflectance peaks.

The method of 18, wherein the at least one interferometric light modulator of the plurality of pixel elements each comprising an optical cavity having an open state and a closed state, wherein the at least one interferometric light modulator of the plurality of pixel elements are configured to have essentially the same spectral response in an open state and essentially the same spectral response in a closed state.

An interferometric light modulating device, comprising:

• a plurality of pixel elements, each pixel element comprising an interferometric light modulator switchable between different reflective states;
• and
• an illumination apparatus configured to selectively illuminate the plurality of pixel elements with light of different color at different times.

An interferometric light modulating device, comprising:

• means for interferometrically modulating light switchable between different reflective states;
• and
• means for selectively illuminating said means for interferometrically modulating light with light of different color at different times.
