Abstract:
1. A display comprising: at least one interferometric modulator configured to selectively reflect light incident thereon, the at least one modulator having a first spectral response across substantially the visible light spectrum, the first spectral response further having a spectral peak centered in the green portion of the visible light spectrum; and at least one filter positioned in front of the at least one interferometric modulator so as to receive the selectively reflected light from the at least one interferometric modulator and configured to selectively transmit visible wavelengths associated with magenta light, the filter having a second spectral response characterizing transmission through the filter over the visible spectrum, the second spectral response having two portions corresponding to transmission of red and blue wavelengths and a non-zero reduced portion of the spectrum therebetween, wherein a combination of the at least one interferometric modulator and the at least one filter has a third spectral response lower than the first spectral response of the at least one interferometric modulator due to the at least one filter being configured to remove at least a portion of the said light selectively reflected by the at least one interferometric modulator to output white light, and wherein the at least one interferometric modulator includes a reflective surface and a partially reflective surface defining an optical cavity, the optical cavity having an optical path length that is substantially equal to one half of a wavelength associated with green light.
