Interferometric modulator with dual absorbing layers
First Claim
1. An electromechanical display apparatus, comprising:
- a reflective display pixel includinga reflector;
a first partially transmissive absorbing layer disposed from the reflector, the first absorbing layer and the reflector defining a first gap therebetween, the first gap having a thickness dimension of distance d1;
a second partially transmissive absorbing layer disposed from the first absorbing layer such that the first absorbing layer is between the second absorbing layer and the reflector, the second absorbing layer and the first absorbing layer defining a second gap therebetween, the second gap having a thickness dimension of distance d2; and
wherein at least two of the reflector, the first absorbing layer and second absorbing layer are movable to either increase or decrease the thickness dimension of the first gap and the second gap,wherein the sum of the thickness of the first absorbing layer and the second absorbing layer is between about 3 nm and 12 nm.

Abstract
This disclosure provides systems, methods and apparatus related to an electromechanical display device. In one aspect, an analog interferometric modulator includes a reflective display pixel having a reflector, and a movable first absorbing layer positionable at a distance d1 from the reflector, the first absorbing layer and the reflector defining a first gap therebetween. The apparatus also includes a second absorbing layer disposed at a distance d2 from the first absorbing layer, the first absorbing layer disposed between the second absorbing layer and the reflector, the second absorbing layer and the first absorbing layer defining a second gap therebetween. In addition, at least two of the reflector, the first absorbing layer and second absorbing layer are movable to synchronously either increase or decrease the thickness dimension of the first gap and the second gap.
