ABSTRACT:
By varying the spacing between two surfaces, one of which is disposed in front of the other, an interferometric modulator selectively creates constructive and/or destructive interference between light waves reflecting off the two surfaces. The desired spacing can be achieved by deforming one or both surfaces. A heating element associated with a particular surface causes the deformation by heating the material that forms one or both of the surfaces. By varying the amount of applied heat, the amount of deformation is varied, thus allowing the distance between the surfaces to be controlled and thereby creating constructive and/or destructive interference as desired.
