Abstract
Methods, systems, and apparatus for resetting a micro-mirror devices. In one aspect, a micro-mirror device includes a mirror plate tiltable about a hinge, two electrodes located on different sides of the hinge, a memory storing state data for the electrodes, and a state modifier operable to receive the state data for the electrodes from the memory and, during a reset of the mirror plate, change the state for at least one of the electrodes from the state specified by the state data stored in memory to a different state.
