摘要： Various implementations described herein involve interferometric modulators (IMODs), which may be single-mirror IMODs (SMIs). Such IMODs may include an absorber stack and a mirror stack. The absorber stack and the mirror stack may define a gap therebetween and may be capable of being positioned in a plurality of positions relative to one another to form a plurality of gap heights. A hinge area may physically connect the mirror stack and an anchor area. Some such IMODs have hinge areas without any metal layer. However, the hinge area may be capable of forming an electrical connection with at least one metal layer of the mirror stack. For example, such IMODs may have a hinge area that includes a non-metal conductor.
