    摘要： Methods are described for selecting reflective layer distances in an interferometric modulator display that result in reduced color sensitivity to temperature and process variation. Colors are selected for interferometric modulator subpixels that correspond to a minimum in the rate that the colors change with respect to reflective layer distance. In some cases, colors are selected that deviate from the minimums in order to obtain a desired target color (e.g., a desired white point).

    摘要： Various embodiments include an interferometric modulator device configured to provide improved saturation. In some embodiments, saturation is improved by optically matching the impedance of two materials with different refractive indices using a multilayer having a refractive index gradient. In various embodiments, the thickness one or more of the layers in the multilayer are selected to provide increased saturation. Accordingly, in various embodiments the multilayer having a refractive index gradient helps to narrow the resonance of a pixel such that the band of wavelengths that are reflected from the pixel is smaller. In turn, a device including a combination of red, green and blue pixels may expand the spectrum of colors that are reflected by the device in operation. Additionally, there may be better contrast between whites and blacks, as darker blacks with less hue are produced.
