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.

Abstract: This disclosure provides systems, methods and apparatus for improving the reliability of dual actuator light modulators by equalizing voltages provided to the two actuators of the light modulator. A pixel circuit for driving the dual actuator light modulator can include a data loading circuit coupled to an actuation circuit. The data loading circuit is utilized to store data received from a controller for a pixel associated with the light modulator. The actuation circuit is utilized to control a first actuator and a second actuator of the dual actuator light modulator based on the data stored by the data loading circuit. The actuation circuit includes a first stabilization capacitor and a second stabilization capacitor for stabilizing voltages provided to the first and second actuators. The actuation circuit also includes an equalization switch for equalizing voltages provided to the first and second actuators.

Abstract: A display apparatus includes an array of light modulators. Each light modulator has a first actuator configured to drive the light modulator into a first state and a second actuator configured to drive the light modulator into a second state. The display apparatus also includes a control matrix including, for each light modulator in the array, a single actuation voltage interconnect. The actuation voltage interconnect is configured to apply a first drive voltage to the first actuator of the light modulator and apply a second drive voltage to the second actuator of the light modulator. In addition, the actuation voltage interconnect is configured to control application of a data voltage to a latch circuit to control the application of the first and second drive voltages to the first and second actuators.
