Abstract:

This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display. A pixel circuit used to control one or more display elements of a MEMS display apparatus can include a first output node coupled to a first actuator of a display element and a second output node coupled to a second actuator of the display element. The first output node can be coupled to an actuation interconnect via a first pre-charge switch connected in parallel with a first capacitor. The second output node can be connected to the actuation interconnect via a second pre-charge switch connected in parallel with a second capacitor. Energizing the first output node or the second output node can cause the display element to enter or remain in a first state or a second state, respectively.
