A display apparatus comprises an array of pixels including a transparent substrate, and a plurality of MEMS-based light modulators; and a control matrix disposed on the substrate. The control matrix includes, for a pixel in the array of pixels, i) a writc-enabling interconnect for enabling the pixel to respond to a data voltage, ii) an actuation voltage interconnect for providing a voltage sufficient to actuate the pixel, iii) a first switch for selectively governing the application of the voltage provided by the actuation voltage interconnect to the pixel, and iv) a data voltage interconnect for controlling the first switch. The control matrix thereby regulates the application of the actuation voltage across an actuator included in a respective light modulator, thereby empowering the light modulator to change states to form an image.
