One embodiment of a display system includes a first array that defines multiple reflective devices each movable between an inactive position to reflect light to a light dump and an active position to reflect light to an imaging region, a second array that defines multiple reflective devices each movable between an inactive position to reflect light to the light dump and an active position to reflect light to the imaging region, and an activation device that projects an activation beam to the devices to move individual ones of the devices between the active position and the inactive position, wherein the first array, the second array and the activation device are housed within a single vacuum enclosure.

An apparatus of one embodiment of the invention is disclosed that includes a number of micro-electromechanical (MEM) devices, a charge source, and at least one discharge path. Each MEM device has a plurality of different states based on a charge induced thereon. The charge source is to induce the charge thereon such that the MEM devices each enter one of the states. The at least one discharge path is for the plurality of MEM devices, and along which the charge induced thereon is dischargeable.
