摘要： This disclosure provides systems, methods and apparatus for an electromechanical system. In one aspect, an electromechanical interferometric modulator system includes a substrate and a plurality of interferometric modulators (IMODs). At least two different IMOD types correspond to different reflected colors. Each IMOD has an optical stack, an absorber layer, a movable reflective layer, where the movable reflective layer has at least open and collapsed states, and an air gap defined between the movable reflective layer and the optical stack in the open state. The optical stacks define different optical path lengths for each of the different IMOD types by way of different transparent layer thickness and/or material, while the air gap has the same size when in the open state. The IMODs reflect different colors in the closed state and a common appearance in the open state. Use of two absorbers aids in defining the common appearance in the open state and can also improve color saturation.

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light and for determining spacing between light turning features in the light guide. In one aspect, a light intensity profile along a first axis is determined and the pitch of light turning features along that first axis is varied based upon this profile, while the pitch along a second crossing axis (for example, an orthogonal axis) and the sizes of the light turning features remain unchanged. In some implementations, an apparatus includes a light guide having an array of light turning features configured to turn light from at least one light emitter. The light turning features can be non-uniformly spaced apart along a first axis such that pitches vary non-monotonically and, along a second axis that crosses the first axis, the light turning features are spaced apart with substantially the same progression.
