ABSTRACT:
An apparatus for use with a digital micro-mirror includes a hinge disposed outwardly from a substrate and capable of at least partially supporting a micro-mirror disposed outwardly from the hinge. The micro-mirror capable of being selectively transitioned between an on-state position and an off-state position based at least in part on a bias voltage received by a conductive conduit. The apparatus also includes a conductive layer disposed inwardly from the at least one micro-mirror. In one particular embodiment, the conductive layer enables a conductive path for the bias voltage substantially inwardly from a periphery of the micro-mirror.
