Abstract

This disclosure provides systems, methods and apparatus for addressing an array of pixels in a display. In one aspect, an electromechanical device includes a movable element coupled between a first and second actuator, and a charge distribution circuit arranged to electronically couple the first actuator to the second actuator and capable of equalizing a potential between the first actuator and the second actuator. In certain implementation, a method for addressing an array of pixels in a display, where a given pixel in the array of pixels includes a light modulator coupled between first and second actuator capacitors, includes equalizing a potential between the first actuator capacitor and the second actuator capacitor prior to discharging and re-charging the actuator capacitors. Equalizing a potential may include transferring charge from one actuator capacitor to another actuator capacitor until the voltage across each actuator capacitor is approximately equal.
