摘要： Methods are described for selecting reflective layer distances in an inter ferometric 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.
摘要翻译：各种实施例包括经配置以提供改善的饱和度的干涉式调制器装置。在一些实施例中，通过使用具有折射率梯度的多层光学匹配具有不同折射率的两种材料的阻抗来改善饱和度。在各种实施例中，选择多层中的一个或多个层的厚度以提供增加的饱和度。因此，在各种实施例中，具有折射率梯度的多层有助于缩小像素的谐振，使得从像素反射的波长带更小。反过来，包括红色，绿色和蓝色像素的组合的装置可以扩展在操作中由装置反射的颜色的光谱。此外，白人和黑人之间可能会有更好的对比，因为产生了较少的色调。

摘要： This disclosure provides systems, methods and apparatus for writing data to a display. The frame rate is improved by simultaneously and independently writing data to multiple common lines of the display. In some implementations, lines of common color are written simultaneously. In some implementations, more common lines of lower visual importance are written simultaneously than common lines of higher visual importance. In these implementations, colors of higher visual importance can be displayed at a higher resolution to maintain good image quality while still improving frame rate. Display element electrodes may be coupled along common lines in various ways to implement simultaneous writing to multiple common lines.
