Hybrid color synthesis for multistate reflective modulator displays

A display device comprising:

• first means for optically modulating light between at least a first color, a second color, and a third color;
• second means for optically modulating light between the first color, the second color, and the third color;
• first means for filtering light modulated by the first modulating means;
• and
• second means for filtering light modulated by the second modulating means, wherein the first filtering means has a different spectral transmittance than the second filtering means.

A method of generating an image, the method comprising:

• providing a display device comprising a plurality of optical modulators comprising a first set of optical modulators and a second set of optical modulators, each optical modulator of the plurality of optical modulators configured to be selectively switched among at least a first state, a second state, and a third state, each state having a different spectral reflectance, and a filter on a reflective side of the plurality of optical modulators, the filter comprising 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 having a different spectral transmittance than the second set of filter elements;
• directing light from a light source onto the display device;
• and
• selectively switching the plurality of optical modulators between the states.
