Abstract
A method and device for manipulating color in a display includes a display in which one or more of the pixels includes one or more display elements, such as interferometric modulators, configured to output colored light and one or more display elements configured to output white light. Other embodiments include methods of making such displays. In addition, embodiments include color displays configured to provide a greater proportion of the intensity of output light in green portions of the visible spectrum in order to increase perceived brightness of the display.
