1. A device, comprising:
- a movable membrane including a partially reflective mirror;
a substrate positioned on a first side of the movable membrane; and
a light source positioned on a second side of the movable membrane and configured to emit light incident on the second side of the movable membrane,wherein the movable membrane is configured to move from a first position to a second position,wherein with the movable membrane in the first position visible light of a desired wavelength range passes through the movable membrane and through the substrate, andwherein with the movable membrane in the second position substantially all of the visible light of the desired wavelength range is blocked.

Abstract
A transmissive micromechanical device includes a substrate, an optical stack over the substrate and a moveable membrane over the optical stack. The moveable membrane may include a partially reflective mirror and be configured to move from a first position to a second position. When the movable membrane is in the first position the transmissive micromechanical device is configured to pass light of a predetermined color and when the movable membrane is in the second position, the micromechanical device is configured to block substantially all of light incident on the substrate.

18. A transmissive display, comprising:
-
a transparent substrate; a first reflecting layer disposed on a first surface of the transparent substrate; a movable membrane including a second reflecting layer, wherein the second reflecting layer and the first reflecting layer form a variable optical cavity; and a light source, wherein the movable membrane is positioned between the light source and the transparent substrate, and wherein the light source is configured to emit light incident on the movable membrane, wherein the variable optical cavity is adjusted as the movable membrane moves from a first position to a second position, and wherein when the movable membrane is in the first position, the movable membrane allows transmission of wavelengths in the range of ultraviolet or infrared light, and absorbs substantially the entire wavelength range of incident visible light. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
