摘要：Methods and apparatus are described by which charge may be delivered to an array of electromechanical devices (e.g., MEMS or NEMS) driven in parallel such that only a desired number of the devices are actuated. Specific embodiments relate to visual displays implemented using interferometric modulators (IMODs). In particular, spatial half-toning techniques for achieving grayscale in such displays are described that are not characterized by the power penalty associated with conventional spatial half-toning techniques.
