摘要： Systems, methods and apparatus are provided for electromechanical systems devices having a non-uniform gap under a mechanical layer. An electromechanical systems device includes a movable element supported at its edges over a substrate by at least two support structures. The movable element can be spaced from the substrate by a gap having two or more different heights in two or more corresponding distinct regions. The gap has a first height in a first region below the gap, such as an active area of the device, and a second height in a second region adjacent the support structure. In an interferometric modulator implementation, the second region can be encompasses within an anchor region with a black mask.

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 modulator having a waveguide and a microdisk resonator is disclosed. The waveguide has an input port for receiving a light signal of wavelength λ and an output port for transmitting modulated light. The microdisk resonator has a resonance at λ and is coupled to the waveguide between the input and output ports such that at least 10 percent of the light traveling in the waveguide is coupled to the microdisk resonator. The microdisk resonator further includes a material having a first state and a second state, the material absorbing more of the light in the first state than in the second state. The first and second states are selectable by a signal that is applied to the microdisk resonator. In one embodiment, the waveguide and the microdisk resonator occupy different portions of a sheet of material having the various layers used to construct the resonator.

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： Air gap variation in an interferometric modulator over a two-dimensional spatial map of the modulator is determined by acquiring a digital photograph of the modulator. Color parameters of individual pixels in the photograph are determined and compared to a model of color parameters as a function of air gap distance. The model and individual pixel color parameters may be plotted on a color space plot for comparison. The determined distances may be plotted over a two-dimensional spatial map of the interferometric modulator to visualize the mirror curvature and air gap variation.
