Abstract

This disclosure provides systems, methods and apparatus related to an electromechanical display device. In one aspect, an analog interferometric modulator (AIMOD) includes a reflective display pixel having a movable reflective layer and a stationary absorber layer, the reflective layer and absorber layer defining a cavity therebetween. A color notch filter may be employed to produce an improved white state. In some implementations, the color notch filter is positioned on a side of the substrate opposite the absorber layer. In some other implementations, the color notch filter is positioned between the substrate and the movable reflective layer.

First claim

What is claimed is:

1. A device, comprising:
an analog interferometric modulator (AIMOD) including
a substrate having a forward side that is exposed to receive incident light and a rearward side opposite the first side;
a first electrode disposed rearward of the substrate;
an absorber disposed rearward of the substrate;
a second electrode rearward of the first electrode and the absorber such that there is a cavity between the second electrode and the first electrode;
a re…
