METHOD AND DEVICE FOR GENERATING WHITE IN AN INTERFEROMETRIC MODULATOR DISPLAY
First Claim
1. An array of interferometric modulators configured to appear to have a white color, the array comprising:
- a first plurality of color interferometric modulators wherein each modulator reflects a first color light; and
a second plurality of color interferometric modulators wherein each modulator reflects a second color light,wherein the combined reflected light from only the first plurality of color interferometric modulators and only the second plurality of color interferometric modulators appears substantially white.

Abstract
Various embodiments of the invention relate to methods and systems for generating the color white in displays created from interferometric modulators and more specifically, to the generation of the color white through the use of reflected light at two wavelengths. In one embodiment, a display device displays the color white. The color white is generated by reflecting light from two pluralities of interferometric modulator types. The first modulator type reflects colored light at a specific wavelength. The second modulator type reflects colored light selected to be at a wavelength complementary to the first. The combined light reflected from the two types appears white in the display.
