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： A microelectromechanical (MEMS) device includes a substrate, an actuation electrode over the substrate, a reflective layer over the actuation electrode, and a support layer between the actuation electrode and the reflective layer. The reflective layer includes at least one aperture through the reflective layer. The support layer includes a recess between the actuation electrode and the at least one aperture. Upon application of a control signal to the device, at least a first portion of the reflective layer is configured to move into the recess and at least a second portion of the reflective layer is configured to remain stationary. The reflectivity of the MEMS device is dominantly modulated by changing a phase difference between light reflected from the first portion and light reflected from the second portion.

摘要： This disclosure provides systems, methods and apparatus for providing white light color output from an electromechanical systems (EMS) device with reduced likelihood of stiction. In one aspect, interferometric modulators are configured to provide a white color output while having a non-zero modulator gap dimension. Such a feature can reduce problems associated with zero modulator gap dimensions such as stiction. Various methodologies can be used to yield such a non-zero modulator gap and a white color output. In some implementations, for example, an optical element that introduced wavelength dependent phase shift is used. In some implementations this wavelength dependent phase shifting optical element includes a stack of color filters, a hologram, a diffraction grating, or layers of material having specific thicknesses and wavelength dependent indices of refraction.

摘要： A field-sequential color architecture is included in a reflective mode display. The reflective mode display may be a direct-view display such as an interferometric modulator display. In some implementations, the reflective mode display may include three or more different subpixel types, each of which corresponds to a color. In some such implementations, the colors include primary colors. Data for each color may be written sequentially to subpixels for that color, while subpixels of the remaining colors are written to black. Alternatively, data for each color may be written sequentially to all subpixels of the display. Flashing of a corresponding colored light, e.g., from a front light of the display, may be timed to immediately follow a process of writing data for that color.
