Abstract

A method of providing control signals for resetting mirror elements (10,20) of a digital micro-mirror device (DMD) having reset groups (FIG. 4), or for resetting moveable elements of other micro-mechanical devices that operate with similar principles. A bias voltage is applied to the mirrors and their landing sites, and an address voltage is applied under the mirrors. (FIG. 3). The address voltage is held at an intermediate level except during a reset period. During this reset period, the address voltage is increased. Also, during reset, the bias applied to mirrors to be reset is pulsed and offset, and the bias applied to mirrors not to be reset is increased. (FIGS. 5 and 6).
