Abstract: Systems and apparatuses for hybrid micro-driver architectures having time multiplexing for driving displays are described. In one embodiment, a display (e.g., hybrid display architecture) includes a backplane and a micro-driver circuitry that is coupled to the backplane. The backplane includes circuitry (e.g., sample and hold circuitry) for sampling and holding analog data and for time multiplexing analog data. The micro-driver circuitry includes at least a capacitor of a ramp generator for generating a ramp voltage based on the analog data of the backplane and drive circuitry to cause at least one emission pulse for emitting a display element.
