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.
