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.
