Display circuit incorporating data feedback loop

摘要

This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display device. The state of operation of the light modulator can be controlled by the pixel circuit based on a data voltage stored in a data storage element of the pixel circuit. The pixel circuit includes an actuation circuit for providing an actuation voltage to the light modulator and a feedback circuit for providing a positive feedback voltage from an output node of the actuation circuit to an input node of the actuation circuit. In some implementations, the feedback circuit includes the data storage element connected between the input node and the output node.
