First Claim
Patent Images
1. A method of fabricating a display comprising:
- selecting a diffuser having an optical response; and
disposing the diffuser in front of an interferometric modulator array, the interferometric modulator array having an optical response that depends on angle of view,wherein selecting the diffuser comprises substantially matching the optical response of the diffuser and the optical response of the interferometric modulator array to reduce angular color shift with angle-of-view of the display.

8. A method of tailoring optical properties of a display comprising an interferometric modulator having a spectral responsivity and a diffuser having an optical response, the method comprising:
selecting at least one property of the diffuser with reference to the spectral responsivity of the interferometric modulator so as to reduce color shift of the display. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

20. A method of limiting view of a display to authorized viewers, the method comprising:
-
selecting at least one interferometric modulator having a spectral responsivity that depends at least in part on angle of view of the display; reflecting light indicative of an image from the at least one interferometric modulator, the interferometric modulator being configured to at least partially obscure the image from view; and diffusing the reflected light from the at least one interferometric modulator with a diffuser having an optical response, wherein the optical response of the diffuser is configured to so as to decrypt the image. - View Dependent Claims (21)
