Abstract
A display device including a plurality of optical modulators and a plurality of filter elements on a reflective side of the plurality of optical modulators is provided. The plurality of optical modulators includes a first set of optical modulators and a second set of optical modulators. Each optical modulator of the plurality of optical modulators is configured to be selectively switched among at least a first state, a second state, and a third state. Each state has a different spectral reflectance. The plurality of filter elements includes a first set of filter elements corresponding to the first set of optical modulators and a second set of filter elements corresponding to the second set of optical modulators. The first set of filter elements has a different spectral transmittance than the second set of filter elements.
