Patent ID: 7385762

Claim:
A device comprising: an array of at least two interferometric modulators, each interferometric modulator comprising: a substrate; an optical layer positioned over the substrate, the optical layer being at least partially transmissive to incident light; a mirror positioned over the substrate and movable between a first position spaced from the optical layer by a first distance and a second position spaced from the optical layer by a second distance, the first distance being greater than the second distance, and the mirror having a surface facing away from the substrate, wherein light reflected by the interferometric modulator is interferometrically modulated; and at least one stationary member contacting the surface of the mirror when the mirror is in the first position, wherein the at least one stationary member is configured to inhibit movement of at least a portion of the mirror when the mirror is in the first position; wherein the stationary members of the at least two interferometric modulators contact the surface of each respective mirror at a different first distance from the optical layer when the mirrors are in the first position.
