Abstract
Various reflective display pixels are provided. In one embodiment, among others, a reflective display pixel for modulating the return of incident visible light is provided that includes one or more stacked cells. Each cell includes a fluid containing a light absorbing medium capable of absorbing incident light in at least one specified wavelength band for that cell and a light returning medium capable of selectively returning at least a portion of the light within the specified wavelength band for that cell. In other embodiments, each cell includes a fluid containing a light absorbing medium capable of absorbing incident light in at least one specified wavelength band for that cell and a light returning medium capable of selectively returning at least a portion of visible light outside the specified wavelength band for that cell.
