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.

Abstract: An illumination device, comprising a reflective optical cavity (2104, 2116) including a plurality of light-transmissive regions (2108) through which light can escape the reflective optical cavity (2104, 2116); a light source (2118) arranged to introduce the light into the reflective optical cavity (2104, 2116); a plurality of light modulators (2102), each having at least first and second states, wherein, in the first state, a light modulator (2102) obstructs a corresponding light-transmissive region (2108) thereby preventing light introduced into the reflective optical cavity (2104, 2116) from illuminating an image pixel that corresponds to the light-transmissive region (2108), and in the second state, the light modulator (2102) allows light escaping the reflective optical cavity (2104, 2116) through the corresponding light-transmissive region (2108) to illuminate the image pixel corresponding to the light-transmissive region (2108).
