Abstract: A display includes an array of light modulators each having a first actuator and a second actuator. A control matrix includes a circuit having a first state inverter having an output coupled to an input of a second state inverter. A data store capacitor is coupled to an input of the first inverter and configured to store a data voltage corresponding to a future pixel state of the pixel. A first update interconnect is coupled to the first state inverter and configured such that altering a voltage applied to the first update interconnect causes the first actuator to respond to the stored data voltage. A second update interconnect is coupled to the second state inverter and configured such that altering a voltage applied to the second update interconnect causes the second actuator to respond to a voltage state of the first inverter.

Abstract: The systems and methods described herein relate to electronic circuits and methods for control of light sources in displays. The circuit includes a plurality of light sources, for instance light emitting diodes, connected to a common power supply. An illumination control system regulates current to the light sources in coordination with a field sequential color imaging algorithm. The light sources can be illuminated either simultaneously or in a timed sequence.
