Abstract: This disclosure provides systems, methods and apparatus for controlling the states of a light modulator used in displays. A display apparatus includes pixels circuit for controlling the state of operation of dual actuator light modulators. The pixel circuit can be implemented using three transistors and a capacitor. In particular, the pixel circuit can include a charge-discharge transistor, a data transistor, and a feedback transistor. The charge-discharge transistor is used to both selectively charge and selectively discharge an output node of the pixel circuit coupled to the light modulator. The data transistor enables loading a data capacitor with data voltage representative of image data. The feedback transistor provides positive feedback to allow the output node to be charged to the actuation voltage via the charge-discharge transistor.
