    摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, a passivation layer is attached to the light guide of an illumination device. The passivation layer may be an optically transparent moisture barrier and may have a thickness and refractive index which allows it to function as an anti-reflective coating. The passivation layer may protect moisture-sensitive underlying features, such as metallized light turning features that may be present in the light guide. The light turning features may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

    摘要： Disclosed herein are methods and systems for testing the electrical characteristics of reflective displays, including interferometric modulator displays. In one embodiment, a controlled voltage is applied to conductive leads in the display and the resulting current is measured. The voltage may be controlled so as to ensure that interferometric modulators do not actuate during the resistance measurements. Also disclosed are methods for conditioning interferometric modulator display by applying a voltage waveform that causes actuation of interferometric modulators in the display.

    摘要： Methods of making MEMS devices including interferometric modulators involve depositing various layers, including stationary layers, movable layers and sacrificial layers, on a substrate. Apertures are formed in one or more of the various layers so as to form a non-planar surface on the movable and/or the stationary layers. Other layers may be formed over the formed apertures. Removal of the sacrificial layer from between the resulting non-planar movable and/or stationary layers results in a released MEMS device having reduced contact area and/or a larger surface separation between the movable and stationary layers when the MEMS device is actuated. The reduced contact area results in lower adhesion forces and reduced stiction during actuation of the MEMS device. These methods may be used to manufacture released and unreleased interferometric modulators.

    摘要： Interferometric modulators having a separable modulator architecture are disclosed having a reflective layer suspended from a flexible layer over a cavity. The interferometric modulators have one or more anti-tilt members that inhibit undesirable movement of the reflective layer, such as curling and/or tilting. The stabilization of the reflective layer by the anti-tilt members can improve the quality of the optical output of the interferometric modulators, as well as displays comprising such interferometric modulators.

    摘要： Methods and systems for determining power consumption in displays are described. In some cases, the power may be determined by determining the capacitance of each pixel in the display, where the capacitance may be different for pixels in bright and dark states and for pixels of different color.
