An apparatus includes a plurality of display elements arranged in an array and a control matrix coupled to the plurality of display elements to communicate data and drive voltages to the display elements. For each display element, the control matrix includes an actuation circuit coupling a voltage source to the display element. The control matrix is configured to apply an actuation voltage to an actuator of the display element throughout an actuation stroke of the actuator and to initiate the actuation of the actuator after a pre-charging signal that initiated the application of the actuation voltage to the actuator has been deactivated.

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.
