Method and device for corner interferometric modulation
First Claim
1. A display, comprisinga first light-transmissive substrate portion, said first substrate portion comprising a first surface and a second surface;
- a second light-transmissive substrate portion fixed relative to the first substrate portion, said second substrate portion comprising a first surface and a second surface, wherein said first surface of said second substrate portion is oriented at a first non-zero angle to the first surface of the first substrate portion;
at least a first reflective element supported by the second surface of the first substrate portion, wherein said first reflective element has a first reflectivity which changes in response to a first signal, wherein the first reflectivity of the first reflective element comprises a range of wavelengths reflected from said first reflective element, said range of wavelengths changing in response to said first signal; and
at least a second reflective element supported by the second surface of the second substrate portion.

Abstract
A display is described, wherein the display includes surfaces arranged at a non-zero angle to one another. A least one of the surfaces may include an interferometric modulator. Compensation for color shift can be provided through the use of two or three surfaces arranged at an angle to one another, the surfaces having similar interferometric modulators. Methods of making such a display are also described. A brighter display can be provided through the use of three surfaces arranged orthogonally to one another, where each of the surfaces has an interferometric modulator which reflects a different color of light. Either additive or subtractive methods can be used to generate light of a particular color.
